This will inevitably leave an area of color mis- match that will be not accepted by the patient cheap serophene 25 mg. When the scalp is used, the size and form of the skin grafts should be drawn on the surface before any subcutane- ous infusion is applied. Four good-sized pieces of skin autografts can usually be obtained from the scalp: One anterior piece from ear to ear posterior to the hair line One posterior piece from vertex to the occipital region Two lateral pieces from the retroauricular region to the neck The scalp is infiltrated with epinephrine-containing normal saline (1:200,000) until large flat areas are obtained. The larger guards should be used to obtain good-quality grafts with appropri- ate width. The assistants should hold the head and the anesthetist control the ET tube while the harvesting is in process. Pressure must be exercised on the opposite part of the head to maintain the countertraction. Two assistants are necessary, main- taining pressure on the periphery of the skull to leave the entire area around the top of the scalp ready for harvest. After harvesting, epinephrine-soaked (1:10,000) Telfa dressings are immediately applied and left in place for 10 min. The scalp is then dressed in the standard fashion (either Biobrane or Acticoat dressings). When the entire face must be grafted, the scalp will not provide enough skin grafts. An alternative donor site is chosen (the backprovide large amounts of good quality skin), and all skin grafts necessary to graft the entire face are taken from the same area to provide excellent color match. It is important to preserve the donor site that might be used for face grafting in order to provide the best quality of skin. A master plan is developed shortly after admission, and, if at all possible, the donor area to be used for face burns is spared. Donor sites are also infiltrated with large amounts of normal saline with epinephrine and powered dermatomes are used.
By carefully select- ing muscles and observing the distribution of abnor- malities generic serophene 50 mg with visa, the electromyographer can distinguish among radiculopathy, plexopathy, myopathy, and many other conditions. USING ELECTRODIAGNOSIS IN PAIN MEDICINE Electrodiagnosis is useful when pain is thought to originate from neurologic, intrinsic muscular, or neu- romuscular junction disease. As with all medical interventions, before ordering, ask yourself: Will the test be of practical value? Will an accurate diagnosis change any aspect of the treatment plan or provide other benefits? If you wish to look for or rule out particular conditions, mention them. A well- run electrodiagnostic laboratory should: Ensure the most comfortable experience possible for the patient. Control for skin temperature during NCS, and record temperatures in the report. Fibrillation Have a consistent set of norms for NCS data, and potentials (a) are short-duration potentials occurring in a regular present these norms in the report for comparison. Positive sharp waves (b) are similar to fibrillation poten- Abnormal data should be clearly marked. Complex repetitive discharges (c) may be the result of ephaptic transmission causing Compare abnormal results against the contralateral repetitive, rhythmic firing of irritable muscle fibers. The EMG signal as a EMG of the thenar muscles is quite painful and whole has a characteristic appearance and recruitment should be reserved for atypical or unusual presenta- tions where additional information is needed. Abnormalities in any of these parameters help to diagnose the type and chronicity of disease When abnormalities are found on one limb, the con- tralateral limb should also be studied. The list is incomplete; interested readers are referred to more comprehensive texts. EMG and NCS may be extremely painful in the CRPS patient, and MYOFASCIAL PAIN AND increased analgesic therapy may be required.
