This procedure must be repeated ment between the ribs (and the implant) and the spine. This does not happen when spinal rods are inserted, even This technique has several major advantages over without fusion. A particularly welcome feature is the conventional operations performed on the spine itself, stimulation of spinal growth, including at sites where the which generally involve a fusion of the affected spinal growth zones are lacking (with the unilateral bar). The stiff stabilization at the spine itself provokes our colleagues, working together with Dr. Campbell, has a spontaneous fusion after about 3 years, even if no active confirmed the existence of this growth. The operation, and resulting tion results in growth stimulation, as we have also learned expansion, are not performed on the spine, which reduces from leg lengthening procedures. The drawbacks of this technique are the need to repeat On the contrary, the shortened side of the spine is stimu- the lengthening and the high costs of the implant.

During excision of extensive burn wounds generic coumadin 2 mg otc, patients will require transfusion of large amounts of blood order 2mg coumadin free shipping, often an exchange volume or more. Massive blood Anesthesia 129 transfusions are associated with a variety of complications, which can be mini- mized but not entirely avoided by careful practice. A variety of techniques have been utilized to decrease surgical blood loss during burn excision. Limb tourniquets or compressive dressings at sites of wound excision or skin harvest help to minimize bleeding. Some centers use epinephrine- soaked dressings or topical epinephrine spray to induce local vasoconstriction. Epinephrine solution can also be injected subcutaneously or beneath the burn eschar. The epinephrine solutions appear to be well tolerated but the effectiveness of these maneuvers is uncertain. Another method is to spray topical thrombin solution (1000 U/ml) on bleeding surfaces before application of compressive dressings. Despite all these interventions, blood loss during extensive excisions is still prodigious. Coagulopathy is one of the more prominent complications associated with massive blood transfusion. Packed red blood cell preparations (PRBCs) are essentially devoid of platelets and whole blood stored for more than 24 h does not possess significant numbers of functional platelets. Whole blood contains essentially normal levels of coagulation factors, with the exception of the volatile factors V and VIII. Because most plasma is removed from PRBCs, they provide a poor source of coagulation factors. Massive blood loss and transfusion with PRBCs or whole blood results in dilutional losses of both platelets and factors V and VIII. Thrombocytopenia is the most common cause of nonsurgical bleeding after massive blood transfusion. In general, 2–4 blood volumes of blood or PRBCs must be transfused before bleeding due to thrombocytopenia will develop. Ob- served platelet counts usually remain higher than calculated values due to release of platelets from sites of sequestration.
