The 90 Musculoskeletal Diagnosis decision to treat surgically is largely guided by the patient’s comor- bidities generic 100mg topamax free shipping, expectations, and degree of symptoms. The most common sur- gery for hip osteoarthritis is total hip replacement. Acetabular fractures are less common and typically require a high energy trauma. Additional diagnostic evaluation: X-rays, including AP and lateral views, are indicated. Treatment: Surgery is indicated, and the sooner the fracture is reduced, the better. Treatment: Surgery is indicated, and the sooner the hip is reduced, the better. Pes anserinus bursitis, Osgood-Schlatter disease, osteochondritis dis- secans, and fractures are among the other less likely causes you will need to consider. Pain at the joint line is the result of a collat- eral ligament or meniscus problem (or both) until proven otherwise. Pain at the tibial tuberosity in a young patient is Osgood-Schlatter’s syndrome until proven otherwise; anterior knee pain may be a patello- femoral disorder; pain over the medial tibial plateau, approximately 2 inches below the joint line, may be pes anserinus bursitis; and pain and swelling in the posterior knee may be a Baker’s cyst. When did your pain begin, what were you doing at the time, and what were the initial symptoms? In fact, having already ascer- tained the location of pain, knowing the mechanism of injury and From: Pocket Guide to Musculoskeletal Diagnosis By: G. If the patient has a ligament injury, the patient will report a deceleration injury or twisting the knee that led to immediate symptoms of swelling and pain. In fact, 30 to 50% of patients will report actually hearing a “pop” at the time of injury. In contrast, patients with meniscus injuries may have a similar mech- anism of injury (twisting or deceleration), but the patient will not notice swelling (if swelling occurs at all) until minutes or hours after the injury. In an older patient, a meniscus injury may be more insidious and the patient may not recall an inciting traumatic event. Likewise, patients with osteoarthritis, patellofemoral syn- drome, and Osgood-Schlatter’s syndrome have a more chronic onset of symptoms. Do you experience any grinding, locking, catching, or giving way of the knee? This question is the last general high-yield question for most cases of knee pain. Grinding is characteristic of osteoarthritis; locking and catching are characteristic of meniscus injuries and osteochondritis dissecans (meniscus injuries are much more common than osteo- chondritis dissecans); and giving way is more characteristic of liga- mentous injuries. This question is specifically targeting the diagnosis of patello- femoral syndrome. Patients with patellofemoral disorders classi- cally report pain with prolonged knee flexion, and pain relief with knee extension. The “movie theater sign”—in which the patient complains of aching knee pain while sitting with the knees flexed in the theater for a prolonged period of time—is classic for patel- lofemoral syndrome. Often, to relieve the pain, the patient will report extending the leg into the aisle. The answer to this question is most useful for gathering a general gestalt for the patient’s complaint. It may not add any specific diag- nostic utility, but it will give a better overall picture for the patient’s problem. Have you tried anything to help the pain and, if yes, has that been successful?

Diligent postoperative care is needed to assess continually any continuing blood loss and transfuse additional blood products as they are indicated by clinical course and results of laboratory studies order topamax 100 mg with amex. Monitoring of central venous pressure and urine output also helps in guiding postoperative blood and fluid therapy. Ventilation may be impaired in the postoperative period whether breathing is spontaneous or mechanically controlled. Blood gases and oxygen saturation can be used as guides to ventilator management. Patients with inhalation injury benefit not only from rational ventilator management but also from a program of inhaled bronchodilators and mucolytics combined with judicious airway suc- tioning. Extubated patients require supplemental oxygen for at least the first few hours until the effects of general anesthetics resolve. Airway support may also be necessary initially in these patients until they are more alert and responsive. Postoperative hypother- mia can result in vasoconstriction, hypoperfusion, and metabolic acidosis. Radiant heaters, blood and fluid warmers, warm blankets, heated humidifiers for gas delivery, and high room temperatures are all useful in the postoperative period to provide warmth to the recovering patient. SUMMARY The most important practical principles of anesthetic management of burn patients were described in the introduction but should be repeated for emphasis. Periopera- tive management of burned patients presents numerous challenges, both technical and cognitive. Safe and effective anesthetic management of these patients requires detailed knowledge of the continuum of pathophysiological changes associated with burn and inhalation injuries from resuscitation through healing of wounds. In addition, optimal patient care is possible only when it includes close communi- cation with the surgeon. Modern advances in burn care rely on coordination of the efforts of a large team of specialists. The anesthetic plan should be compatible with the overall treatment goals for the patient. The anesthetist joins the burn care team when the anesthetic plan is coordinated with the overall treatment goals for the patient.

HISTORY OF BURN EXCISION Although early excision and grafting has been considered a procedure of the late 20th century; it was actually first described by Lustgarten in 1891. The fire at the Cocoanut Grove Nightclub in Boston in November, 1942, brought new insight into many aspects of the care of burned patients. Cope suggested then that patients with early wound closure had improved survival. Several reports are scattered throughout the literature over the next 30 years [2–4], but results were discourag- ing since they showed little clinical improvement from the usual practice of waiting for spontaneous eschar separation followed by grafting on granulation tissue. Janezekovic reported good results in 1970 with sequential shaving of burns of varying depths in. The surgical community began to take notice; however, the need to estimate the depth of burn and ancillary support required for a major burn excision made acceptance of this technique difficult.

The use of a high kV technique is often desirable discount topamax 200 mg fast delivery, but not all generators are capable of the short exposure times necessary purchase topamax 200mg on line. Where the range of selectable mA values is limited and where the minimum exposure time is 0 buy cheap topamax 100mg on line. It is recommended that the minimum additional filtration for paediatric ex- aminations is 1mm aluminium plus 0. This additional filtration need not be permanently placed within the x-ray tube but the facility made available to add filtration to the tube when required. Voltage In spite of recommended high kV techniques, low kV paediatric examinations continue to be undertaken. High voltages facilitate the use of short exposure times and the extremely short exposure times needed for paediatric radiographic examinations can only be achieved if a high frequency (or 12-pulse) generator is used. The use of added filtration can allow the utilisation of high kV techniques with longer exposure times when operating older equipment (see ‘Tube filtra- tion’ above). Anti-scatter grids The use of anti-scatter grids in the radiographic examination of infants and young children is generally accepted as unnecessary. Paediatric examinations undertaken with the use of anti-scatter grids result in increased radiation dose to the patient and therefore their continued use should be questioned if diag- nostic radiographs of satisfactory quality can be produced without them. Fluo- roscopic equipment should also have the facility to quickly remove and insert grids and once again, the necessity of the use of a grid in the examination of 7 young children should be questioned. Screen film systems Although advancing technology is quickly bringing in the digital age, many imaging departments still operate a film/screen imaging system and therefore it is important to consider their value as a method of reducing patient dose. High- speed systems result in a lower patient dose and allow shorter exposure times to be used therefore minimising movement unsharpness. However, these obvious advantages must be balanced against the reduction in image resolution Radiation protection 27 and detail that also occurs. The European Guidelines on Quality Criteria for Diagnostic Radiographic Images in Paediatrics5 clearly advocate that film/screen systems with a speed class of less than 400 should not be used unless specific detail is necessary for accurate diagnosis. Digital systems Digital imaging technology permits a wide range of exposure parameters (and therefore patient doses) to be used without significantly affecting the perceived image quality. It is therefore essential that appropriate exposure parameters are established and adhered to in order to ensure minimum patient dose. Ideally the kV/mAs combination used should be sufficient to ensure that the noise in the image is just low enough for the image quality to be diagnostically acceptable. Automatic exposure control Many automatic exposure control (AEC) systems commonly available are not suitable for paediatric imaging due to the large and relatively fixed position of the ionisation chambers. The constant growth that occurs during childhood results in changing body proportions and no fixed AEC device could be effec- tively used for all age ranges. Care also needs to be taken as many ionisation chambers are situated behind an anti-scatter grid and, if the grid is not removed prior to exposure, this will result in an increased patient dose. The use of expo- sure charts relating radiographic technique to patient weight (or age for extrem- ity radiography) is likely to be a better option if dose reduction is to be successfully achieved. Automatic brightness control Fluoroscopy can result in large patient doses if unnecessary grids are not removed (see ‘Anti-scatter grids’ above) or the radiologist or radiographer does not correctly use or apply their knowledge of the equipment. A simple method of reducing patient dose if imaging a large area containing contrast agent (e.
