It can arise not only from pathology afecting any of the structures located within the pelvis and lower abdomen, but also related areas such as the skeletal system, nerves or muscles. When a specifc pathophysiological cause is identifed, management is tailored to this. However, for some women the underlying cause of their pelvic pain will never be identifed and this can be challenging. In these instances, a multi-disciplinary approach should be used for both assessment and optimal management, to reduce the risk of fragmented care. This article focuses on the general strategies of management, rather than the treatment options for each of the multiple conditions that can contribute to chronic pelvic pain. Ten years ago, I would have psychosocial distress and sexual dysfunction, risk being told you that no one knew anything about pelvic pain. Today, I labelled as difcult or needy and may struggle to be can tell you that we have learned a lot in the last few years. There believed when accessing healthcare services is still a great deal to be learned.

To be taken seriously as a patient with genuine pain the hidden nature of pelvic pain generates a culture of secrecy which can isolate and embarrass, causing feelings 3. Chronic pelvic pain may for women with or without identifed pathology create tension at work and at home, and have a profound 4. Chronic pelvic pain can arise from pathology afecting any of Women with chronic pelvic pain also have a higher incidence the structures located within the pelvis and lower abdomen, of other chronic pain syndromes, such as bladder pain as well as other structures related to these areas. Malignant disease is often excluded from lists of this type although it is well recognised as a cause of pelvic pain between these conditions. Six months is defned may occur where the brain has difculty discerning where as the cut-of point between acute and chronic pain.

While this is occurring treatment for sinus infection in toddlers buy tinidazole australia, the chief cells release pepsinogen which the strong acid environment converts to the active proteolytic enzyme pepsin antibiotics have no effect on quizlet tinidazole 500 mg cheap. To summarize thus far antibiotics for acne work discount 1000mg tinidazole fast delivery, hydrochloric acid and sodium and/or potassium bicarbonate are produced (an acid and a base) antimicrobial dressings for wounds buy line tinidazole, the acid being pumped into the stomach antibiotics for kidney infection buy 500 mg tinidazole with mastercard, the bicarbonate into the blood stream and many calories of energy are expended antibiotics for dogs with swollen glands tinidazole 1000 mg otc. Pepsin and the acid work together to unfold, or denature, any protein that was consumed during the meal. These two substances attack the amide linkages that join amino acids together in the protein macromolecule. Soon the lower pyloric sphincter opens and this acidic chyme begins to enter the duodenum. First, any glucose in the chyme stimulates the release of a group of very short-lived (half-life is about two minutes) but powerful substances called incretins. Their effects are to increase insulin secretion and inhibit glucagon secretion, increase beta cell mass and insulin gene expression in the pancreas, and to inhibit acid secretion and gastric emptying in the stomach. Figure 1 27 Secretin Inhibits Gastric Acid Production and Stimulates Bicarbonate Production In addition to causing the release of the incretins, the entry of the chyme into the duodenum triggers the release of another powerful hormone called secretin. In this process, bicarbonate (or pancreatic juice) is delivered to the duodenum via the pancreatic duct along with the various pancreatic enzymes. The epithelial cells of the biliary ducts also produce bicarbonate in preparation for the release of bile. The pH of the intestine must be lightly alkaline for the pancreatic enzymes (the lipases, proteases and amylases) to be maximally effective. Balancing this system, again through what we eat and drink, is crucial for optimal health. A study 44 published in 2006 reported the same finding within six days of initiating a diet containing 20 grams or less of carbohydrates per day. The authors, although impressed with the results, could offer no mechanism by which the improvements occur. We believe that it may be the protein that is consumed with a meal that may be the key factor in the observed clinical improvements. In contrast, a meal containing large amounts of carbohydrates and fat with very little protein would not significantly reduce the acid present. The protein blends used in the Ideal Protein Protocol contain large amounts of protein isolates. This narrow range is exquisitely controlled by many mechanisms and involves the lungs, the kidneys, the stomach and the pancreas. For example, the lungs through hyperventilation may expel more carbon dioxide which would exert an alkalizing effect on the blood. The kidneys may adjust the pH of the urine to assist in maintaining acid/base equilibrium. As a rule, these processes are largely autonomic, and we can do relatively little to effect their functioning. Here we can greatly influence the ability to buffer our blood through our choice of foods. These products are produced in a one to one ratio; that is for every one molecule of acid, there is one molecule of bicarbonate produced. To illustrate how proper acid/base balance should work, it is helpful to assign some fictitious values. Then, it would also produce 10 molecules of bicarbonate which would be released in the blood stream. To accomplish this, it must produce at least 6 molecules of bicarbonate (5 to neutralize the acid and 1 to slightly alkalinize the environment). To produce 6 molecules of bicarbonate, it must also release 6 molecules of acid into the blood stream. Because the stomach introduced 10 molecules of bicarbonate into the blood, the addition of 6 molecules of acid here present no problem. The Effects of Drinking Soda We are often asked if diet sodas are permitted on the Ideal Protein Protocol, Diet Coke being, by far, the most popular brand inquired about. High glycemic carbohydrates cause an outpouring of insulin with trans-fats leading to the production of the series two eicosanoids and a large influx of acid, with hardly any protein. How Bicarbonate Buffers the Blood Maintaining the proper concentration of bicarbonate in the blood is hugely important in acid/base homeostasis. The bicarbonate ion is a buffer, a substance that resists changes in pH both increases and decreases. She found that bicarbonate levels steadily declined, until by age 90 they were 18% of what they were at 45. In a study published in February 2008, Arnett showed that osteoclastic activity is directly related to pH. In bone organ cultures, H+-stimulated bone mineral release is almost entirely osteoclast-mediated with a negligible physiochemical component. The pH level of the gastric juice increases (the stomach becomes less acidic), and the patient experiences a relief from the burning sensation; however as the pH continues to rise (to about 4. People attempting protein diets using whole food sources of protein must keep this in mind. In the Ideal Protein Program, patients are required to take alkaline mineral supplements containing calcium, magnesium, and potassium. The patients are also required to consume four cups of fresh vegetables per day, contributing additional alkalizing minerals and anti-oxidants. Ideal Protein participants are further encouraged to use sea salt, pink or gray in color instead of commercially 31 bleached table salt on their foods, which provide a rich source of alkaline minerals, and they are educated on the perils of highly acidic soft drinks. How long term use of these pharmaceuticals impact the overall physiology has not been studied; however, it has been an observation, both in our clinic and in the pharmacy, that many patients taking these medications are also taking a biphosphonate (such as Fosmax, Actonel, or Boniva ). If the body becomes too acidic, perhaps due too insufficient bicarbonate buffering, it must draw on the alkaline mineral reserves of the bones. We believe that a nutritional approach via the Ideal Protein Protocol may well represent a therapeutic alternative for medication intolerant patients. We recommend based on our experience, switching from a proton-pump inhibitor to a H2 antagonist may represent a better therapeutic option. Of course, if these changes are not effective or bring a worsening of symptoms, the proton-pump inhibitor may certainly be re-started. Within seven years of its introduction, Ideal Protein has positioned itself as the premier weight loss protocol in Canada, with well over 1500 establishments. Hopefully, you may begin to see that many of the health benefits of the program go far beyond mere weight loss. Presentation of a New Animal Model and Mechanistic Studies in Human Apo A-1 Transgenic and Control Mice. By addressing obesity with consistent counseling, eating plans and ongoing monitoring, physicians can go beyond treating symptoms and help patients achieve a healthy weight, potentially avoid chronic illnesses and live longer lives. Partnerships work When patients, physicians and employers organize weight management around these principles, they achieve positive results that benefit everyone. To illustrate, Wausau, Wisconsin-based Aspirus Heart and Vascular implemented a pilot weight loss protocol with 50 employees and family members, and the resulting weight loss and improvement in metabolic markers was so significant that the self-insured health system decided to offer it to their entire employee base of 6, 500 people. In a study presented at Obesity Week 2016, Aspirus followed 306 employees who had successfully completed the same medically developed weight loss protocol and analyzed claims costs for these employees from 2013 to 2015. Results from the study, Effect of the Ideal Protein Weight Loss Protocol on Employee Healthcare Costs, indicated an average of $916. These finding indicate that employers can potentially save between $500 and $1000 annually per employee on medical claims. Additionally, payers and employers should develop more focused, local resources to address obesity including hiring trained specialist and dieticians trained in safe, scientifically based weight-management techniques, including low carbohydrate, ketogenic diets. Educating employees about avoiding sugar and excess carbohydrates is also helpful. With collaboration and initiative, physicians and payers can support patients as we together, reverse the tide of obesity and realize the benefits of better health and lower healthcare costs.

Finally, suggestions will be provided improve the risk factors associated with obesity.

Suction Good suction is of paramount importance in anaesthesia and resuscitation and for all forms of surgery and intensive care antibiotics for bad uti order 500mg tinidazole overnight delivery. As a resuscitation tool, suction comes second only to a self-inflating bag and mask. When you need suction, it must be instantly available, right by your hand at all times: the sucker must be ready and switched on for any case where a full stomach is suspected or where the airway is being inspected, such as when you are looking for a foreign body or other obstruction the sucker must be ready, but can be turned off, for elective procedures. Never believe that a sucker is working until you have raised the tip to your ear and heard its power. Make sure the suction tubing will not kink when angled and that the suction motor is protected by a reservoir bottle and a filter. Suction in the trachea A small-bore soft sucker is used for tracheal or bronchial suction. Special precautions are needed if sucking in the trachea: the sucker should be sterile, not the same one as used for the pharynx. In children, the sucker should not be a tight fit in the small tracheal tube, otherwise the negative pressure may cause lung collapse. Removal of foreign bodies Removal of foreign bodies is a common job for anaesthetists in developing countries. Children often hide small coins in their mouths which may slip down into the pharynx. After inhalation induction with halothane, a long straight blade laryngoscope is best to go behind the larynx. The child will be apnoeic during pharyngoscopy, so a pulse oximeter should be connected. An object further down in the oesophagus may be out of reach and may require intubation and oesophagoscopy. An assortment of other items may have been inhaled or become lodged in the upper airway: seeds, fish bones, chicken bones, peanuts, bits of plastic, bottle tops and even leeches. For the airway, there are three general situations: Total airway obstruction Partial airway obstruction with an object caught at the larynx Inhaled smaller foreign body further down in the trachea or bronchi. Stand behind the patient, give a sharp upward 13 thrust into the epigastrium (round the front) with both fists to raise intrathoracic pressure and expel the blockage. There is intense irritation for the patient and stridor may be caused by laryngospasm as well as by the object itself. Though theoretically this may push the object further down, in practice that rarely happens. Do not declare the job complete until you are sure everything has been removed and breathing is comfortable and silent. Unfortunately, the commonest situation is for a seed or peanut to be inhaled by a child past the cords and into a bronchus. If a severely anaemic patient is to be subjected to surgery, which may cause blood loss, and to anaesthesia, which may interfere with oxygen transport by the blood, all possible steps must be taken to correct the anaemia preoperatively. If time is limited, it may be possible to do this only by transfusion, after consideration of the possible benefits and risks. The decision to anaesthetize a patient depends on the circumstances and on the urgency of the need for surgery. However, a patient with a ruptured ectopic pregnancy cannot be sent away with iron tablets or even wait for a preoperative blood transfusion. Possibilities include sickle-cell disease, chronic gastrointestinal bleeding from hookworm infection or a duodenal ulcer. Emergency surgery An anaemic patient with an urgent need for surgery has a lower oxygen carrying capacity of the blood than normal. Avoid drugs and techniques that may worsen the situation by lowering the cardiac output (such as deep halothane anaesthesia) or by allowing respiration to become depressed. Blood lost must be replaced with blood, or the haemoglobin concentration will fall further. This degree of hypertension will be associated with clinical signs of left ventricular hypertrophy on chest X-rays and electrocardiograms, retinal abnormality and, possibly, renal damage. Patients whose hypertension has been reasonably well controlled can be safely anaesthetized. After a full assessment of the patient, including obtaining a chest X-ray and an electrocardiogram and measuring serum electrolyte concentrations (especially if the patient is taking diuretic drugs), you may carefully use any suitable anaesthetic technique, with the exception of administering ketamine, which tends to raise the blood pressure. If the patient is receiving treatment with beta blockers, the treatment should be continued, but remember that the patient will be unable to compensate for blood loss with a tachycardia, so special attention is needed. It is not safe simply to start antihypertensive drugs the day before an operation. Severely hypertensive patients whose need for surgery is not urgent should be referred. There are, firstly, the problems of anaesthetizing a patient with a severe systemic illness, who may have nutritional problems and abnormal fluid losses from fever combined with a poor oral intake of fluid and water and a high metabolic rate requiring a greater supply of oxygen than normal. Tracheal tubes may quickly become blocked with secretions, so frequent suction may be necessary. In sick patients who cannot cough effectively, a nasotracheal tube may be left in place after surgery or a tracheostomy performed to allow for aspiration of secretions. Contamination of anaesthetic equipment with infected secretions must also be considered. If you have to anaesthetize a patient with tuberculosis, use either a disposable tracheal tube, which you can then throw away, or a red rubber tube which, after thorough cleaning with soap and water, can be autoclaved. If you cannot see how to overcome contamination problems with inhalational anaesthesia, use ketamine or a conduction technique instead. Special inquiry must be made about any former use of steroids, systemically or by inhaler. Any patient who has previously been admitted to hospital for an asthmatic attack should be referred for assessment. The patient with chronic bronchitis has some degree of irreversible airway obstruction. The patient must be told to give up smoking completely at least four weeks before the operation. Simple clinical tests of lung function may be valuable; healthy people can blow out a lighted match 20 cm from the mouth without pursing their lips and can count aloud in a 13 normal voice from 1 to 40 without pausing to draw breath. The nature of the operation is of great importance; elective surgery on the upper abdomen is contraindicated, since respiratory failure in the postoperative period is likely. Conduction anaesthesia combined with intravenous sedation with small doses of diazepam may be a better choice of technique than conduction anaesthesia alone or general anaesthesia. If general anaesthesia is necessary, premedication with an antihistamine such as promethazine, together with 100 mg of hydrocortisone, is advisable. It is important to avoid laryngoscopy and intubation during light anaesthesia, as this is likely to lead to severe bronchospasm. Ketamine is quite suitable for intravenous induction because of its bronchodilator properties. Ether and halothane are both good bronchodilators, but ether has the advantage that, should bronchospasm develop, epinephrine (0. This would be very dangerous with halothane which sensitizes the heart to the dysrhythmic effects of catecholamines. Aminophylline (up to 250 mg for an adult by slow intravenous injection) can be used as an alternative to epinephrine if bronchospasm develops; it is compatible with any inhalational agent. At the end of any procedure that includes tracheal intubation, extubate with the patient in the lateral position and still deeply anaesthetized; the laryngeal stimulation might otherwise again provoke intense bronchospasm. Postoperatively, give oxygen at not more than 1 litre/minute via a nasal catheter. Be careful with opiates, as the patient may be unusually sensitive to respiratory depression. Make a full Low blood sugar is the main preoperative assessment, looking especially for symptoms and signs of intraoperative risk from peripheral vascular, cerebrovascular and coronary disease, all of which are diabetes Monitor blood sugar levels and common in patients with diabetes, as is chronic renal failure. In the short term, the only major theoretical risk is that undetected hypoglycaemia 13 might occur during anaesthesia. Most general anaesthetics, including ether, halothane and ketamine, cause a small and harmless rise in the blood sugar concentration and are therefore safe to use. Thiopental and nitrous oxide have little effect on the blood sugar concentration; no anaesthetic causes blood sugar to fall. As an alternative, if frequent blood sugar measurements are impossible: Put 10 International Units of soluble insulin into 500 ml of 10% glucose to which 1 g of potassium chloride (13 mmol) has been added Infuse this solution intravenously at 100 ml/hour for a normal-sized adult Continue with this regimen until the patient can eat again and then return to normal antidiabetic treatment. However, make regular checks of blood glucose concentration and change the regimen, if necessary. Note that, if glass infusion bottles are used, the dose of insulin will need to be increased by about 30%, as the glass adsorbs insulin. Where several patients are due to undergo surgery on a given day, diabetic patients should be first on the list, since this makes the timing and control of their insulin regimen much easier. Because certain drugs (notably chlorpropamide) have a very long duration of action, there is some risk of hypoglycaemia, so the blood sugar 13 concentration should be checked every few hours until the patient is able to eat again. If difficulties arise with these patients, it may be simpler to switch them temporarily to control with insulin, using the glucose plus insulin infusion regimen described above. Emergency surgery the diabetic patient requiring emergency surgery is rather different. If the diabetes is out of control, there is danger from both diabetes and the condition requiring surgery. The patient may well have: Severe volume depletion Acidosis Hyperglycaemia Severe potassium depletion Hyperosmolality Acute gastric dilatation. In these circumstances, medical resuscitation usually has priority over surgical need, since any kind of anaesthesia attempted before correction of the metabolic upset could rapidly prove fatal. Resuscitation will require large volumes of saline with potassium supplementation (under careful laboratory control). There is no point in giving much more than 4 International Units of insulin per hour, but levels must be maintained either by hourly intramuscular injections or by continuous intravenous infusion. If the need for surgery is urgent, use a conduction anaesthetic technique once the circulating volume has been fully restored. Before a general anaesthetic can be given, the potassium deficit and acidosis must also have been corrected, or life-threatening dysrhythmias are likely. The level of blood sugar is much less important; it is better left on the high side of normal.

Management Patients with Group 2 injuries should be serially examined antibiotics for uti penicillin cheap tinidazole online amex, since the injuries may worsen or progress with time bacteria mod minecraft 125 order discount tinidazole on-line. Medical adjuncts may also be helpful (steroids antibiotic yeast discount tinidazole 1000mg line, anti-refux medications infection urinaire femme buy generic tinidazole 300mg line, humidifcation infection japanese song buy cheap tinidazole 1000mg line, voice rest antibiotic prices buy tinidazole australia, antibiotics). Evaluation Direct laryngoscopy or esophagoscopy should be performed in the operating room. Evaluation Disruption of the airway occurs at the level of the cricoid cartilage, either at the cricothyroid membrane or cricotracheal junction. These patients will present with severe respiratory distress, necessitating urgent airway evaluation and management. Management Tracheotomy is necessary to secure the airway, but can be very difcult due to the altered anatomy. Complex laryngotracheal repair must be performed through a low cervical incision (see below) after the airway is secured. Informed Consent When possible, surgical consent should always be obtained prior to the performance of surgical procedures. In the case of laryngeal trauma, informed surgical consent of the patient is critical, as multiple proce dures over an extended period of time are sometimes required to repair and rehabilitate patients who sufer these injuries. Likewise, the efects of laryngeal trauma can have long-term impacts on quality of life, afecting the functions of speech, swallowing, and breathing. When informed consent from the patient is not possible due to the emergent nature of the injury, every efort should be made to obtain informed consent from a reliable family member or guardian. Perioperative Care the goal of perioperative management in laryngeal trauma is to prevent progression of the injury and promote rapid healing. More severe injuries will require longer periods of hospitalization and rehabilitation. Speech pathology consultation should be obtained as early as possible after the initial laryngeal injury. Airway manifestations of inhalation injury may be extremely severe, as the upper airway absorbs the bulk of the thermal injury sufered during inspiration. Since inhalation injuries may occur without skin burns or other external injuries, a high index of suspicion must be maintained. A history and careful description of possible inhalation injuries should be elicited from either the patient or a witness to the event. The full extent of airway compromise after inhalation injury may not be evident until 12 to 24 hours after the injury, so symptomatic patients should be admitted and observed. The upper aerodigestive tract should be evaluated serially with fexible laryngoscopy to follow the evolution of the injury. If acute upper airway obstruction is impending or immi nent, the most experienced clinician in airway management should intubate the patient and secure the airway. Once an inhalation injury is diagnosed, a multidisciplinary team consisting of otolaryngologists, pulmonologists, and respiratory therapists should be utilized to maxi mize pulmonary and respiratory care. During surgical repair, the endolarynx is generally best approached through a midline thyrotomy, along with a transverse incision through the cricothyroid membrane. If a concomitant median or paramedian vertical thyroid fracture happens to be present, it may also be used to gain access to the endolarynx. If the fracture is located more than 3 mm from the anterior commissure, however, a midline thyrotomy should still be performed. All major endolaryngeal lacerations should be repaired with 5-0 or 6-0 absorbable suture. Even minor lacerations that involve the true vocal cord margin or anterior commissure should be closed. If the anterior attachment of the true vocal cord is severed, it should be resuspended by suturing the anterior end of the cord to the external perichondrium. After tracheotomy, the patient with signifcant laryngeal edema should be evaluated with direct laryngoscopy and esophagoscopy to uncover subtle injuries that may be masked by the edema and missed in initial fexible fberoptic laryngoscopy. Adjunctive measures, such as head-of bed elevation, corticosteroids, anti-refux medications, and humidifca tion should be strongly considered. Small, nonprogressing hematomas with intact mucosal coverage are likely to resolve spontaneously without signifcant sequelae. Adjunctive therapies, such as steroids, anti-refux medication, humidifcation, and head-of-bed elevation are helpful. Large or expand ing hematomas may lead to airway obstruction and necessitate placement of a tracheotomy. Recurrent laryngeal nerve injury after blunt laryngeal trauma may be due to either stretching of the nerve or nerve compres sion near the cricoarytenoid joint. While vocal fold mobility will not be regained after even a successful repair due to the mixture of abductor and adductor fbers in the nerve, neural regeneration may prevent muscle atrophy, resulting in improved vocal cord tone and vocal strength in the long term. Displaced thyroid and cricoid cartilage fractures should be reduced and fxed to stabilize the laryngeal framework (Figure 8. If the displaced cartilage fracture occurs in conjunction with an endolaryngeal, soft tissue injury, the cartilage reduction and fxation should be performed prior to endolaryngeal soft tissue repair. This ensures that a proper scafold is obtained before redraping the laryngeal mucosa. If no soft tissue injury accompanies the cartilage fracture, the cartilage may be fxed externally without entering the larynx. In particular, wire fxation poorly maintains the proper anatomic position of the thyroid laminae after fxation, allowing midline fractures to heal in an inappropriately fattened position. When placing a miniplate into the soft cartilage of younger patients, it is often helpful to drill a smaller-than-usual screw hole that results in better purchase for fxation of the screw. Most patients with laryngotracheal separation present with signifcant respiratory distress and require a tracheotomy. Performance of the tracheotomy can be extremely difcult, however, because of the altered anatomy that results from this injury. After laryngotracheal separation, the larynx usually pulls upward and the trachea retracts into a position behind the sternum, necessitating a low tracheotomy incision. Pneumothorax commonly accompa nies a laryngotracheal separation and must be promptly identifed and treated. Following appropriate trauma evaluation and radiologic studies, the patient should return to the operating room for direct laryngoscopy, esophagoscopy, and tracheal repair. The severed ends of the laryngotra cheal complex should be freshened and then closed with nonabsorb able sutures with the knots placed extraluminally. Suprahyoid or infrahyoid release maneuvers may be required in order to allow for a tension-free anastamosis. Most patients with laryngotracheal separation will also have bilateral vocal cord paralysis due to stretching or tearing of the recurrent laryngeal nerves. If the severed ends of the nerves can be located, they should be repaired primarily. When evaluating the stability of the airway, it is important to remember that initially mild signs and symptoms may accompany a very severe laryngeal injury. Further, laryngeal injuries may evolve, progress, and worsen in a relatively short period of time. Therefore, carefully performed fexible fberoptic laryngoscopy is a critical tool in the initial evaluation of the injured airway. Intubation should ideally be avoided, as the endotracheal tube may further traumatize the endolar ynx, destabilize laryngeal fractures, or lead to an acute airway compromise. Airway Stents Stents are often utilized in laryngeal injuries where the anterior com missure is signifcantly disrupted. In these cases, the stent functions to maintain the proper confguration of the commissure and to prevent anterior glottic webs. They are also occasionally used when massive, endolaryngeal mucosal injuries occur. In these cases, the stent helps to prevent mucosal adhesions and subsequent laryngeal stenosis. While the best type of stent is very controversial, solid silastic stents are generally preferred. In austere settings, stents may be fashioned from portions of endotracheal tubes or a fnger cut from a surgical glove and flled with a soft material, such as Gelfoam. Stents are usually left in place for 2 weeks and removed in the operating room via an endoscopic procedure. Tracheotomy Tubes Cufed, nonfenestrated tracheotomy tubes are preferred, as they minimize airfow over the injured larynx. The immediate priority in the treatment of laryngeal injuries is to establish and maintain a stable airway. Airway evaluation should include fexible fberoptic laryngoscopy and a thorough examination of the head and neck. Further, patients with laryngeal injuries should be evaluated serially, as laryngeal hematomas or edema may progress or worsen with time, ultimately leading to airway compromise or obstruc tion. Finally, very mild initial signs and symptoms may occasionally mask a very severe laryngeal injury. If the airway becomes precarious or the patient is at risk of airway compromise, an awake tracheotomy should be performed in the operating room. In general, displaced laryngeal cartilage fractures should be repaired with miniplates to establish a stable laryngeal framework. Mucosal lacerations should be primary repaired with 5-0 or 6-0 absorbable sutures. Stents may be placed if the anterior commissure is signifcantly injured or if there are multiple, severe endolaryngeal lacerations. These stents are usually removed at 2 weeks post-placement via an endo scopic procedure in the operating room. Finally, speech therapy plays a vital role in the recovery and rehabilitation of patients who sufer laryngeal trauma. As in all trauma cases, airway security, maintenance of breathing, and circulation are of primary concern. A complete head and neck exam can often be accomplished in the emergency room or outpatient surgery facility under local anesthesia with or without anesthesia monitoring. For difcult or complicated cases, operative intervention under general anesthesia, particularly in young children or in those patients with polytrauma or life-threatening injuries, may be considered. Surgical goals include functional and cosmetic restoration, while preserving tissue and preventing infection. The information in this chapter is not meant to describe comprehensive, long-term care of all traumatic soft tissue injuries. Rather, it serves as a point of reference for the acute management of most all head and neck soft tissue trauma. Physical Examination y Assess airway, breathing, and circulation according to standard cardiopulmonary life support protocol. Eyes All perioccular injuries mandate an ophthalmology consultation to assess vision, occular pressures, corneal integrity, the anterior and posterior chambers, the lacrimal system, and the retina. Restricted mobility and subconjunctival hemorrhage are suggestive of orbital fractures. Nose y Examine lacerations and determine their depth, cartilage involve ment, and any violation of the mucosal lining. These foreshadow maxillomandibular fractures, and missing teeth present a risk of airway blockage by a foreign body. Neck y Examine for lacerations and even small wounds that could be considered puncture wounds. Scalp y Palpate hair-bearing scalp and examine it for evidence of bleeding where injuries may be concealed. Cranial Nerves y A thorough cranial nerve exam is mandatory, particularly in cases of extensive soft tissue trauma. Like all many neurologic evaluations, though, this is difcult in the obtunded patient. In cases of lacerations and penetrating injuries, nerve sectioning must be ruled out. Contusions and localized infammation can lead to neuropraxia, but this typically presents in a delayed fashion. The extent of injury, though, may be further charac terized with the assistance of ancillary studies. Plain Film Radiographs Plain flm radiographs are primarily useful for evaluating cervical spine status. Typically initiated by the primary emergency medicine or trauma service, they have limited value for assessing most craniofacial trau matic injuries. Cuts of 1 mm or less are optimal, and provide opportunity for more accurate reconstructed coronal images of detailed 3-dimensional reconstructions if desired. Magnetic Resonance Imaging and Ultrasonography There is a limited role, if any, for magnetic resonance imaging or ultrasonography in the management of acute soft tissue trauma. Complete Blood Count A complete blood count can help evaluate blood volume from traumatic loss. However, acute measures may be deceivingly normal if third space fuid volumes have not yet mobilized to the endovascular space.
