Anaphylactic Shock Critical Care Case Study

Anaphylactic Shock Critical Care Case Study Introduction (200 Words) In this project a medical case is going to be studied deeply with literature support as a case study. My topic is about an anaphylactic shock that happened to patient in hospital while I was doing my clinical placement it is a very interesting case to be considered. An evidence-based information will be provided and identified such as: the definition, the symptoms, the diagnostic features and tests, the progress and the treatment and alternatives. The benefits behind studying a case is effectiveness of delivering the information. As stated by Davis and Wilcock, 2014 that it allows the application of theoretical concepts to be demonstrated and will encourage an active learning, increasing the student enjoyment and interest of the topic and their desire to learn and it also provide a developmental key in learning skills such as problem solving, communication and team work. It is an enjoyable and challenging way of studying filled with evidence-based practice that will enhance the level of doing researches and studies that will help in future studies. Nursing Assessment (300 words) The patient has been received in Accident Emergency in resuscitation room (RR). J.A.M 52 years old Bahraini female. The patient had an insect bite in that day while she was walking in public walking area, she stopped walking and itching occurred all over the body. While driving home after the insect bite the patient felt drowsy and hit another car near her house and loss consciousness. J.A.M was brought to the unit by 999 ambulance fully awake, well oriented, alert, afebrile, no respiratory difficulties, no complains of pain, skin is warm and dry, pallor and shivering with rash on the face gave history of feeling nauseated and vomited 4 times. Vital signs Checked and recorded Temperature 37.4C, Spo2 98%, Pulse 118/Minute, BP 145/43, HGT 7.6 Mmol/L. The skin was mainly involved representing pale colour and rash on the face, the cardiovascular system represents tachycardia, and the immune system is responsible for this reaction against the insect bite. The patient denies any chest pai n, denies shortness of breath, the patient is known case of dyslipidemia on tablet Lipitor, no other history of other illness, no history of surgery and no history of any allergy. The patient can handle the basics of activity daily living such as eating, bathing, toileting, dressing and she is able walk and get out of the bed but she is not able to perform certain activities such as food preparation, housekeeping and driving a car. After the acute symptoms have been treated the family should be given health education about how to prevent possible future allergic reaction and the importance of seeking help as quick as possible if they do not know how to deal with the situation. Physical examination was done for cardiovascular system representing chest is equal in shape, no bounding or heaving, no lifting with heartbeat. Upper lower extremities are normal in color and capillary refill within 3 seconds, skin is warm periphery with no edema. S1 is heard in all sites and S2 is heard all sites but louder at base and tachycardia observed. Skin is pale, dry, soft, warm. No edema, lesions or odor, good turgor, no signs of insect bite, rashes on face. Medical Diagnosis and other pertinent medical information (500 words) When received the patient the physician has requested ECG, blood tests as following: Full blood count, Cardiac enzymes, Liver function test, Electrolytes, serum, PT + APTT, ESR. Some of the results was not approved but most of the results were normal, this table shows the most important values and abnormal findings: Date Diagnostic Test Rationale Findings 12/11/14 Electrocardiography (ECG) Can be examined to detect dysrhythmias and alternations in conduction indicative of myocardial damage, enlargement of the heart or drug effects. (Kozier and Berman, 2012) The result is Normal valves, no vegetation observed, the heart produces rapid electrical signal, tachycardia. 12/11/14 Complete blood count (CBC) The CBC identifies the total number of blood cells (Leukocytes, erythrocytes and platelets) as well as the haemoglobin, haematocrit (percentage of blood volume consisting of erythrocytes), and RBC indices. Because cellular morphology (shape and appearance of the cells) is particularly important in accurately diagnosing most hematologic disorders, the blood cells involved must be examined. (Brunner and Smeltzer, 2010) The results are normal except: WBC: 24.5 High. Platelet count: 536 High. Red cell size 20.6 High. Haemoglobin: 8.5 Low. Haematocrit: 0.27 Low. Mean cell volume, Hb, Haemoglobin Con are Low. Band forms: 15. 12/11/14 Fluid (Urea) Electrolytes Fluid and electrolyte balance is a dynamic process that is crucial for life and homeostasis. Potential and actual disorders of fluid and electrolyte balance occur in every setting, with every disorder, and with a variety of changes, that affect healthy people, (e.g., increased fluid and sodium loss with strenuous exercise and high environmental temperature, inadequate intake of fluid and electrolytes) as well as those who are ill. (Brunner and Smeltzer, 2010) Patient Fluid (Urea) electrolytes results are normal. 12/11/14 Serum Initial diagnostic test begin with serum laboratory studies, including but not limited to CBC, complete metabolic panel, prothrombin time/partial thromboplastic time, triglycerides, liver function tests, amylase, and lipase. Studies such as carcinoembrynoic antigen (CEA) and cancer antigen (CA). (Brunner and Smeltzer, 2010) Liver function test are normal. Cardiac enzymes are normal. Creatinine is normal. The patient was diagnosed as having an anaphylactic shock, the case was chosen because it is very common and could happen to anyone by exposure to an allergen of any kind which is in this case an insect bite. The community may not be aware about how dangerous is developing a serious reaction from a small allergen such as insect bite. The statistics was not specified in Bahrain but in some countries worldwide: â€Å"Systemic allergic reactions to insect stings are reported by 0.3% to 7.5% of persons in the United States and Europe’’. (Ruà «ff et al., 2009) An anaphylactic reaction is an acute systematic hypersensitivity that occurs within seconds or minutes after exposure to an allergen or foreign substance. It is a result of the relationship between Antigen and Antibody, The immunoglobin E is the responsible for human allergic reaction. The person may have a hypersensitivity to the venoms of insects (hymenoptera), stings in any part of the body can trigger anaphylaxis . The signs and symptoms includes Itching, nasal congestion, chest tightness, wheezing, cyanosis, dyspnea, generalized itching over the body, urticarial, tacky or bradycardia, pallor, decreased blood pressure, circulatory failure leading to coma and death, nausea, vomiting and diarrhoea. (Brunner and Smeltzer, 2010) All the required tests has been done to the patient in RR except antibody screening which refers to a special protein that is found on the surface of RBC to check for RH positive or negative. (Mayoclinic.org, 2014) IV cannula inserted once received the patient, Injection Hydrocortisone 300mg IV given, Injection promethazine 50mg IV given, Injection adrenaline 0.5mg s/c given, Injection Ranitidine 50mg IV given. Patient put on Cardiac monitor, Dexamethasone 10mg IV given, old file requested, chest x-ray requested, Paracetamol 1g IV, changed the patient and kept clean, Injection rocephin 2g given on Right Arm. The physician advised to be kept on 1.5 litres of Normal Saline for 12 hours, 2-4 litres of Oxygen on nasal cannula, kept the patient covered with necessary blanket to keep her warm and comfortable. Impact of the condition on the patient’s Quality of Life (200 words) The patient may move on to anaphylaxis which is dangerous fatal stage thus the treatment did a great job in reducing this effect by using drugs such as: epinephrine (Adrenaline) which inhibits the mediator release from mast cell and basophils and protect the patient from upgrading to anaphylaxis. The hydrocortisone prevented relapse or protracted anaphylaxis. Lockey, 2014 states that the oxygen therapy will deliver the required oxygen to the patient which makes her comfortable. Promethazine will act on receptor as antihistamine which will reduce the itching and has a sedation effect will put the patient into more comfort. Ranitidine will prevent gastric acid secretion which reduces the nausea and vomiting. Rocephin is an antibiotic which inhibits the bacterial cell wall synthesis and will lead to cell death (Skidmore-Roth, 2012). Normal saline to maintain hydration of the patient. After receiving the treatment patient is feeling better, nausea and vomiting reduced, itching reduced, t he patient is comfortable with the treatment. Discussion (700 words) The patient treatment started with requesting blood tests which shows any abnormal values to be treated. Brunner and Smeltzer, 2010 advised that treatment starts with removing the causative agent which is the insect venom but the patient did not know the exact site of the bite thus physical examination clarified that there is no proof of an insect bite. Brunner and Smeltzer, 2010 admits that the patient should be given the necessary emergency support of basic life functions which was given already to the patient, Epinephrine was given as vasoconstrictive. Brunner and Smeltzer, 2010 states another drug named Diphenhydramine (Benadryl) included in treatment of this condition to reverse the effect of histamine and reducing the capillary permeability but replacement alternative was given which were Promethazine and Ranitidine that acts on H1 and H2 receptors (Antihistamine) (Skidmore-Roth, 2012). Another medication which was stated by Brunner and Smeltzer, 2010 albuterol through nebuliza tion to reverse the histamine bronchospasm if occurred. Brunner and Smeltzer, 2010 recommended that IV lines should be inserted to provide access to administer fluids and medication, IV cannula was inserted to the patient. They also state that respiratory status is measured by monitoring respiratory rate and if there is any abnormal lung sound and pulse rate any rhythm to be monitored regularly, cardiac monitor was put on the patient to assess the respiratory status and vital signs of the patient. The physical examination of the chest clarify that lung sounds are normal. Oxygen was applied to the patient to help compensate breathing pattern. The patient was assessed for previous allergies or exposure to such antigens and the understanding of the patient about this condition to prevent any future complications. Locky, R. 2014 recommended that the family should be educated about how to avoid the allergen and know the underlying causes of any allergy. Lockey, 2014 recommends that the p atient should be given an auto injector which is a syringe that automatically injects single dose of medication when triggered and to be educated about it and the necessary information such as: dose, expiry date, route of administration. Such device is given to many people that are at high risk of developing anaphylaxis only during an anaphylactic emergency. The patient and the family should be also educated about prevention of exposing to the allergen by wearing protective clothes that is covering all the skin when needed to do such sport in public area and the onset symptoms that occurs when already exposed to such allergen. As stated in Brunner and Smeltzer, 2010 there is early simple management that could be done by the patient or the relative by removing the venom or stinger of the insect when found, wound care to be done using water and soap, scratching to be avoided to prevent histamine, to apply ice on the bite site as it will reduce the swelling and decreases the venom abso rption by the body. In my opinion, the patient should be identified by wearing an allergy warning band that contains emergency information in case if the patient fainted or lose consciousness. The allergy should be documented in the patient file to avoid any further exposure to allergy and to avoid using the venom immunotherapy (VIT) which treats certain medical conditions. The patient should be monitored carefully during hospitalization because any adverse complication may occur suddenly. The patient should be referred to an allergist or immunologist to follow up regularly to maximize the quality of life. Conclusion and recommendations (100 words) An allergic reaction could develop anywhere in the nursing practice such as administering certain drug that the patient allergic to or using and device that has an allergen element. Nurses must highly prioritize the general assessment done when receiving patients specially asking for allergy for any medication or substance or any allergic reaction that occurred in the past, because we held such responsibilities to prevent any fatal complications that occurs because of anaphylactic reaction, shock or anaphylaxis. Nurses must be aware of such symptoms to detect an early reaction which could be preventable as soon as possible. This will be beneficial to the patients and nurses to deliver the maximum health outcomes. References Brunner, L. and Smeltzer, S. (2010). Brunner Suddarths textbook of medical-surgical nursing.

Gypsies in Nineteenth-Century England :: European History Essays

Gypsies in Nineteenth-Century England Missing Works Cited Despite the important role Gypsies played in the nineteenth-century, they were not automatically accepted as equals in society. In fact, from the moment they set foot on European soil, the Gyspies were misunderstood and even feared. These feelings became manifest in prejudices, which led to discriminatory actions. At the same time, however, Victorian society found itself fascinated with these strange Gypsies. The gypsy motif in Jane Eyre reflects the ambiguous attitude of Victorian society toward Gypsies. The depiction of "the Gypsy" at Thornfield Hall and the characters' reactions to her are reflections of prejudices based on the Gypsies' skin color, way of life, and traditions, and are also reflections of discriminatory treatment the Gypsies suffered. Simultaneously, many of the descriptions of the Gypsy are also the product of a romanticized view of Gypsies, which manifests itself works of fiction by many other authors throughout the Victorian Era. The Victorians' initial impression of the Gypsies was not a favorable one. At first, the prejudices against Gypsies had obvious sources. Settled society has always had a fear of foreigners, so naturally, "the earliest response to the 'Egyptian' immigrants was rooted, generally, in a xenophobic fear and mistrust of aliens" (Mayall, "British Gypsies" 8). Besides being mistrusted as foreigners, the Gypsies fell victim to racial prejudice because of the color of their skin. Even long before the nineteenth-century, "the conviction that blackness denotes inferiority was already well-rooted in the Western mind. The nearly black skins of many Gypsies marked them out to be victims of this prejudice" (Kenrick and Puxon 19). Even if Charlotte Bronte never saw a Gypsy, she reflects these perceptions of them in her description of "the Gypsy" that visits Thornfield Hall. The Gypsy's most noticeable feature in Sam's mind as he describes her to the assembled guests is that she is "'almost as black a s a crock'" (217, ch. 18). Later, when Jane goes for her interview with the Gypsy, she notes that her face "looked all brown and black" (221, ch. 19). Since the Gypsy turns out to be Mr. Rochester, and there is no indication that he actually blackened his face for his disguise, it may be that the Gypsy's black skin is an imagined product of the characters' preconceived notions about what Gypsies look like. Whatever the case, the fact that Bronte makes the Gypsy's skin color prominent in the characters' description of her reflects the racial prejudice that existed toward Gypsies in Victorian England.

Photography and Pinhole Camera

9/20/2011 11H | Rashad C. Collie| The Pinhole Camera| The Pinhole Camera| How to build a pinhole camera Materials needed:1. Ruler 2. Sturdy cardboard box 3. Black tape 4. Black paper 5. Black paint 6. No. 10 sewing needle 7. Craft knife 8. Aluminum foil 9. Film or photographic paper Instructions:1. Make sure your container is light-proof and allows no light leaks. Cover up any holes, cracks or crevices with black tape, but leave an opening such as a flap to insert and remove film. Boxes should be made of durable cardboard or stiff paper, and lids and flaps should close securely. . Black out your camera. Line the inside of the box with black paper to prevent reflections and to protect against unwanted light filtering through. Preventing light seepage is important, as the light you do allow in to the camera should be very controlled. 3. Cut a ? -inch hole opposite the box opening with a craft knife. Make the pinhole by puncturing a number 10 sewing needle through a small square of alum inum foil measuring about 3-by-2 inches, rotating the needle as you push it through. Stop pushing the needle through when it is halfway in. Tape the foil over the ? -inch hole on the inside of the box. Kodak recommends positioning the pinhole 3 to 6 inches from where the film will be placed. 4. Make the shutter by taping a piece of opaque black paper over the pinhole. You can make a shutter from wood or plastic by screwing it onto the body so that it covers the pinhole completely when not in use. 5. Load the film into the box in a completely darkened room. Use a small square of photographic paper or sheet film like Kodak Tri-X Pan Professional Film. A typical box arger than 3-by-4 inches will need film or paper that measures about 2? -by-3? inches; simply cut to size. Load the film so that the shiny (emulsion) side faces the pinhole. Tape the film or paper down at the corners so that it does not come loose. 6. Exposure refers to the amount of time that film or paper is exposed to light when taking the picture. Keep your camera as steady as possible when taking the picture; you may need to set it down on a flat surface. T he exposure time varies from 2 to 8 minutes for photographic paper and from 1 to 8 seconds for film. Choose the lower end of the spectrum for bright light conditions and the higher end for a cloudy day or dim lighting. Develop as normal. How does a pinhole camera work? A pinhole camera is a simple camera without lens and has a small hole to let light in called an aperture. A pinhole camera is an effectively light-proof with a small hole in one side. Light passes through the aperture and projects an upside-down image on the opposite side of the box. The smaller the hole the smaller and sharper the image will be that is projected.

The Truman Show By Peter Weir - 2021 Words

For centuries, man has dreamt of constructing pristine simulated worlds , existing in a separate sphere from our imperfect reality. From the town of Pullman, a company town south of Chicago to Disney World, attempts to force Utopia have failed, falling prey to the complications of people’s personal desires. The Truman Show, directed by Peter Weir, tells us the story of The Truman Show, an elaborate reality show built around the control of one man’s life. Christof, the director, has created an entire living city for Truman, the star of his show, and the only one not in on this whole elaborate fakery. Essentially, Truman is living his life in the simulation of a flawless, archetypal American town, for the entertainment of millions of viewers around the world. Christof, along with countless others obsessed with the idea of controlling part of the world to fit their visions of an ideal reality, have deluded themselves into thinking fictional utopias can exist apart from the undeniable constraints of reality. Their fundamental flaw lies in relying on the assumptions of psychological behaviorism, and the belief that they could perfectly condition the behavior of the inhabitants follow the goals of the community. In order for Christof’s scheme to work, Truman must be unaware that he’s living in a simulation, and be satisfied with the simulated life that’s presented to him. As much as possible, Christof and his crew try to control every element of Truman’s life.

Rating Othello - 1404 Words

Rating Othello Is this Shakespearean tragedy Othello at the top of the rating chart, or is it just near the top? And why? This essay intends to examine various aspects of this subject, along with critical opinion. This play ranks near the top. The Bard’s presentation of emotions, character, of good and evil actions that are down-to-earth – these are sometimes seen as the main reasons for the high ranking of Othello. Louis B. Wright and Virginia A. LaMar in â€Å"The Engaging Qualities of Othello† maintain that the popularity of this play has been consistent for about 400 years because it treats emotions that are universal and persistent in human nature. Its characters do not exist on a plane far removed from†¦show more content†¦(37) Such human wisdom can be found in Iago’s initial words to sleepy Brabantio: â€Å"Zounds, sir, y’are robbed! For shame, put on your gown! / Your heart is burst; you have lost half your soul.† Indeed, the disappearance of Desdemona from home would seem as such to an elderly father. Human wisdom is obvious again and again; for example, when the senator escorts the general to the council, the duke addresses the â€Å"valiant Othello† without even noticing the senator at first: â€Å"I did not see you. Welcome, gentle signior.† As Othello begins his address before council, he employs much wisdom in the first two verses: â€Å"Most potent, grave, and reverend signiors, / My very noble, and approved good masters,† by being as complimentary as possible, it would seem. Shakespeare’s human wisdom no doubt comes partially from his understanding of the workings of man’s mind. He possesses the ability to analyze in a psychological manner. Harry Levin’s General Introduction to The Riverside Shakespeare includes these comments regarding the psychological aspect of Shakespeare’s characters: During the later eighteenth and most of the nineteenth century, Shakespeare’s interpreters practiced what Bernard Shaw liked to call â€Å"Bardolatry.† They all but deified the Bard of Avon because he was the creator of so many characters who could be treated as if they were human beings – could be identified with, psychologized over [myShow MoreRelatedWhat Makes A Good First Impression?1508 Words   |  7 Pagesclear their good names.

An Analysis of Palestrinas Missa Papae Marcelli and...

An Analysis of Palestrinas Missa Papae Marcelli and Vivaldis Four Seasons Giovanni Pierluigi da Palestrina was an Italian Renaissance composer born in either 1525 or 1526 and dead in 1594. His Missa Papae Marcelli was composed in 1562 during the final session of the Council of Trent, wherein the Catholic Church outlined its catechism in opposition to the Protestant errors in Europe. This Mass fell in the middle of Palestrinas career but is considered to be one of his most popular works. Antonio Vivaldi, on the other hand, was an Italian Baroque composer born in 1678 and dead in 1741. One of his most famous pieces is The Four Seasons, which unlike Palestrinas sacred Mass composition is a secular set of four violin concertos. It was composed in 1723, midway through his career, and is meant to represent as its title suggests the seasons of the year. This paper will compare and contrast Palestrinas Renaissance work Missa Papae Marcelli with Vivaldis Baroque work Four Seasons according to form, harmony, tempo, meter, texture, style period, text (if any), absolu te or programmatic meaning, and sacred or secular orientation. Palestrina was appointed head of St. Peters choir by Pope Julius III. The Renaissance was, indeed, a time when the secular was being exalted. Palestrina showed that not all that was considered secular was bad. For example, he convinced some churchmen that polyphony in music was a good thing. Of course, from there secular music took off on a grand course

Prosthesis in Dentistry

Question: Describe about prosthesis in dentistry. Answer: Introduction Prosthesis in dentistry refers to the process of replacing a single tooth or several teeth as well as missing tissues. If it happens that the teeth are not stable or are missing entirely, they can be restored back by the use of eitherfixed or removable prostheses, a painless solution.In fixed prosthesis, the missing teeth are replaced by the use of bridges or crowns through cementing directly on the teeth. The removable prosthesisfor the teeth are attached to the toothless jaw incase a tooth is totally missing or directly on the teeth or implants, if it is only some teeth which are missing (Li et al., 2013). Under normal circumstances, if one or more teeth are lost this causes the neighboring teeth to move over time. Thus the remaining gaps needs to be filled up early enough while there is still sufficient space to reposition the tooth. If this is not done as early as possible, the body begins to close this gap by moving the nearby teeth and its opposite number on the other jaw. The result of this reposition is occlusion of the mouth, resulting in several consequences for the temporomandibular joints as well as other repercussions on the spine. Protracting and retracting the soft tissues However, the oral cavity is a very difficult area to treat in restorative dentistry since the cheeks, tongue and lips provide difficulties in accessing and visualizing as well as manipulating the instruments to be used for the dental procedures. If not properly used, these instruments can result in the bleeding and injury to the soft tissues.The dental dam provides control and proper access to the tooth for proper preparation and restoration.In case the cervical lesions are at or below the free margin of the gingiva tissues, methods that employ gingival retraction needs to be used. In case the crown or on-lay margins are at or below the free margin, then the tissues needs to be displaces by use of methods that are not likely to cause damage or bleeding to the tissues To protect the soft tissues, I would aspirate and hold the cheek back with my aspirator or I could give the dentist some cotton rolls Ito et al., 2013). In tissue management, therefore, the soft tissues should be placed away from the preparation margins. In the mechanical displacement method, the tissues are physically moved from the tooth aside so that proper visualization as well as treatment can be done. Basically the retraction cord can also be used for this physical displacement. It is preferred by many dentists because it is woven in different sizes and shapes to accommodate the varying thicknesses and diameters of the dental cavity (Zhao et al., 2014). Some other manufacturers have also come up with non-impregnated cords and chemically impregnated cords.Therefore a dentist needs to wear protective latex free gloves when handling these retraction cords. If there is a contamination with latex materials, this can result in an inhibitory effect while setting the vinyl polysiloxane impressions materials leading to gingival tears of the materials used for impression. Importance of shade taking In order to reduce the problems that can arise from selecting of shades in dentistry, it is crucial that the dentists comprehend the art as well as science of shading and color selection. The fact that the appearance of a given color and its perception has both objective and subjective implications may make this process to be difficult. Moreover, the human eye fails to perceive color in a clear, consistent and concise manner due to variation from one person to another (Alshiddi and Richards, 2015). As a result of these differences, the clear understanding of color requires that one understands the dimensions of color accompanied by its value, translucency and specific focus.The inconsistency in the results arising from dental shading due to control of colors has been a problem from time immemorial and hence the need to lay emphasis on this issue. Therefore there needs to be a clear cooperation between the clinician as well as the laboratory technician in the development of better materials to be used for restoration and development of dental adhesives. In addition, these materials should enable the clinician to increase the rate at which translucency and vitality of the teeth becomes after dental restorations. The ceramic restorations should be done while at the same time maintaining optimal color and shading. This is because in the modern world, an attractive smile is an essential part of life as compared to initial perceptions of it being a luxury. This therefore calls for an attractive visual appearance of the person who has undergone dental restoration to be attractive. Therefore determining the color and shading for a dental restoration depends on the environment, illumination and the eyes of the receiver. Importance of laboratory prescription for prosthesis Prosthesis can be prescribed by technicians for instance if the patient lack all teeth and hence this procedure can restore the functions of the mastication using a device which the patient can easily remove and reinsert any time they want. This is because this device replaces all the teeth by use of an acrylic resin support and ceramic teeth. In fact, the more natural the appearance of the dental system is, the closer it resembles that of the face of the respective patient. On the other hand, a partial prosthesis is normally attached to the remaining teeth by the use of hooks. If the dentist uses metallic support structureas anchorage materials, this is referred to as skeletal prosthesis. The charts and records for orthodontic treatment Orthodontic records are needed for carrying out orthodontic treatment plan although the monitoring of the facial growth as well as its development is also of dental clinic importance. Some of the traditionally used charts and records include the intra oral photographs, extra oral photo graphs, dental casts, clinical measurements and radiographic images (Hmmerle et al., 2015).Recently, there has been technological advancement in the digital world as far as dental models are concerned through the application of digital dental set-ups which mimic the actual outcome of the expected orthodontic treatment. Additionally, the application of the three-dimensional imaging on the face has led to development of alternative methods to conduct the documentation of the patient. In order to come up with the final charts or records to be used for a certain patient, it is imperative that the dentist analyzes each record separately for its specific contributions. Range of orthodontic treatments In removable treatment, the removable materials are used to fix the remaining teeth or fill up the spaces left. They consist of a customized plastic base plate with wires and screws attached. They are basically used for simple tooth movement but can also be used for initial stage s of complex treatments (Meyer-Marcotty et al., 2012). The fixed treatment consists of individual brackets which are stuck on the teeth. As a result of this fixing, the tooth movement occurs due to the thin flexible wires as well as elastic bands. The teeth are then slowly moved into their normal positions through little pressure as the wires get adjusted. Orthodontic appliances These instruments, which include interproximal saws, interproximal stripping systems, band seaters, bur kits as well as cutters and pliers, help, ensure practitioners provide patients with exceptional, precise orthodontic care. Several orthodontic instruments are available and differ in functions as well as options. Some are designed for general use, while others are specialized for certain tasks. For instance, the orthodontic cutters can be customized for specific task although they can be also combined with orthodontic pliers. On their own, the orthodontic pliers are to perform arch wire functions such as loop forming, arch wire contouring and torqueing. Other appliances include the bur kits, cutters, band seaters, cassettes and interproximal saws. Orthodontic appliances are of three types- fixed, removable or retainers. Fixed orthodontic appliances- They consist of band cemented to teeth and thin metal wires positions the teeth in the right position. The metal wire is tied to the bands with steel ligature and the bands are made of either metal, ceramic or plastic (Teh et al. 2014). The different stages in fixed orthodontic treatment are as follows: Fitting- In this stage the dentist requires patients records to assess the teeth where fitting is required and metallic spacers to create space for bands and separate back teeth. During the first stage, the X-rays of teeth are taken based on which orthodontist plans treatment for patients. After this fitting is done either by removal of crowded permanent teeth and fitting of braces. Metal or elastic separators are first used to create space for banding teeth and then bands and brackets are bonded to the teeth. Fitting helps in aligning irregular teeth and improving height differentials. For fitting, the dentist requires equipments like adhesive to cement the bond and brackets or archwires are needed to fix bands (Costa et al., 2015). Monitoring- During the monitoring stage, extraction are done after fitting the braces. Working with fixed braces after fitting helps in resolving overbites and closure of space after extractions. Equipments needed by dentist in this stage include rubber bands and brackets with hooks for adjustment. Adjusting- The final stage is the adjustment stage in which adjustment to the braces are done by equipments like changing wires or adding springs or elastics. Finally retainers are used to hold the teeth in new position during debanding appointment (Papageorgiou et al., 2016). Removable braces- This appliance is used when baby teeth are left or when jaw growth needs to be normalized and treatment of lateral incisor cross bite. The removable appliances are retained by dentist by use of equipments like the Adams clasp, Labial arch and the Acrylic Resin framework. Bow is used in removable appliances to retract and retain teeth (Pahkala 2013). The different stages in bonding of removable orthodontic appliances includes the following- Fitting- Fitted resin is used to precisely fix the brackets on cast of teeth. After fixing the brackets on ideal position, a transfer tray is formed on the cast. Monitoring- They are soaked in warm water and trimmed to get the ideal fit for patients. Adjusting- In the final stage, the teeth are isolated and resin is painted in enamel and brackets. The trays (removable devices) are finally removed and brackets get bonded to the teeth (Levrini et al. 2013). The main equipment required in this process is the resin and removable tray that can be used by the dentist. Retainer- Retainers are made of wires or plastic to realign teeth after surgery or fixing braces. Use of retainers in new position helps the periondontal fibers to adapt to changes in bone and reduce any changes in final tooth position. Retainers may be of two types- fixed retainers made of thin wires bonded in the lower or upper front of the teeth and the removable retainers held in place by hook or clasps (Vig 2013). The stages in fixing retainers are- Fitting- An impression of the new teeth is taken on a mold and retainer is fabricated out of wire. Monitoring- After fixing retainers, it is necessary to regular monitor the patients to check for any cavities and cleaning the teeth. Dentist ensures that the retainer is fixed in place. Adjusting- After the new teeth is accurately fixed and aligned, the removable retainer are removed. In case of fixed retainers, they are used to ensure that braces do not shift back to the previous position. These are worn by the patient as specified by the orthodontist. The key equipments needed by dentist in this process include molds, wire, fixing agents to ensure that brace do shift back from its original position (Pahkala 2013). Role of orthodontic nurses An orthodontic nurse is involved in the setting up of the surgery each day and ensures that everything such as patient notes are ready and any work which is required for that that day has been brought from the laboratory (Durkan et al., 2016). They also prepare the required instruments for a particular dental protocol as well as mixing any substances such as composite, bonds, and alginate and glass isonomer. Dental nurses also tidy up the surgery room by disinfection of surfaces and the sterilizationof the dental instruments that have already been used (Dye, 2013). They also make sure that the patients are comfortable before and during dental treatment.
