Burn wounds that are not full thickness are dynamic during the first 48 h generic lamictal 50 mg line. Therefore discount lamictal 50mg otc, advocates for this technique prefer to delay surgery 48–72 h until resuscitation is complete and all burn wounds are stable to avoid the excision of potentially viable tissue discount lamictal 100 mg on-line. It is also accepted that a small delay in definitive treatment is not harmful in burn surgery, although increasing evidence in the trauma and burns literature claims otherwise. Superficial and indeterminate wounds: The same approach outlined before and presented in Chapter 7 can be applied when using this approach. Superficial and indeterminate burn wounds can be treated with temporary skin substitutes after cleansing and superficial debride- ment. Deep-partial and full-thickness burns: Burns of this nature should be treated with the application of topical antimicrobials until definitive surgical treatment is performed. One percent Silver sulfadiazine is the standard treatment in many burn centers, although cerium nitrate–silver sulfadiazine is a very good alternative. Definitive burn wound closure is achieved before colonization by multiply resistant gram-negative bacteria occurs, so no further antimicrobials are usually needed. Wound Management and Surgical Preparation 93 Burn wounds that are serially excised and covered with either autografts or skin substitutes will require the application of different ointments and topical solutions depending on the skin expansion and skin substitute used. Another approach included in this less aggressive group of therapies is the conservative treatment of burns with cerium nitrate–silver sulfadiazine for a week followed by delayed serial burn wound excision. In this therapy, wounds are managed topically with daily application of cerium nitrate–silver sulfadiazine for a week. Patients then undergo surgery on limited areas of their body and return at weekly interval for further excision and autografting. The wounds that are left nonexcised after every operative session are treated with daily application of the same topical agent until complete wound closure has been achieved. In any pragmatic approach, certain patients may not fit in the protocol. In these circumstances, an individual approach needs to be implemented to provide a good outcome. Good examples include the following: Non-life-threatening burns in patients with important associated medical conditions. Medical conditions need to be addressed first to decrease the morbidity and mortality of surgery Large superficial burns with small full-thickness patches are best treated as superficial burns and full-thickness areas addressed last when the rest of the burns are healed. Patients who experience extreme pain not controlled with analgesic regi- mens may benefit from early excision and grafting to decrease daily cleansing. Small deep–partial and full-thickness burns in patients who continue work- ing and attending school are best treated conservatively and operated on as out patients procedures. Burns to the hands and feet benefit from an aggressive approach to permit the patient’s early social and work reintegration PREPARATION FOR SURGERY Burn surgery requires commitment and cooperation from the whole burn team. Treatment of massive burns is an enterprise that matches the complexity of open- heart surgery or any other major surgical procedures based on the interaction of a multidisciplinary team. It should be only attempted in major tertiary hospital facilities where the whole spectrum of specialization is available. Even though burn wound excision and grafting may seem to the novice as a simple and easy surgical procedure, a profound understanding of the burn pathophysiology, dy- namics of wounds, critical care, and wound healing is necessary to perform suc- cessful operations. Burn wound excision, either immediate/early or delayed should be considered an elective procedure and prepared and managed as such. Only emergency surgi- cal airway access and escharotomy and fasciotomy should be undertaken without formal and proper evaluation. Experienced burn anesthetists and burn surgeons only should perform burn wound excision, since minor errors may lead result in the death of patients. Anesthetic Evaluation Destruction of skin by thermal injury disrupts the vital functions of the largest organ in the body and results in a systemic inflammatory response that alters function in virtually all organ systems. All changes that occur during the resuscitation phase and postresuscitation phase should be noted and taken into account to provide safe anesthesia. Treatment of burn patients must compensate for loss of these func- tions, until the wounds are covered and healed.

If the contractures have been present for a If the contractures had been slight, the follow-up prolonged period we recommend lengthening of the knee treatment phase is relatively short, particularly because flexors and follow-up treatment until no further progress the quadriceps will not have adapted by lengthening can be made.

In tion is not carried out until the knee flexor contractures either case, the goal of treatment must be full extension at are very pronounced (80° –90° ), the follow-up treatment the knee.

It is more useful, We use the extension splint as follows: Directly after therefore, to shorten any excessively long knee extensors the operation, the splint is worn at all times (except for in the affected segment and thus restore its proper ten- nursing care procedures). Otherwise a relapse will occur because the patients been achieved, the splint may be worn for shorter periods.

The decision to proceed with surgical lengthening, and particularly the timing of the operation, must be based on the functional handicap and the extent of the deformity rather than the patient’s age. In addition to knee extension, spasticity can also block knee flexion during the swing phase. The result is de- layed flexion, after which there is insufficient time for the extension and the knee remains in the flexed position during foot-strike. This abnormal gait can be documented during gait analyses, and the EMG shows a prolonged, out-of-phase activity of the rectus femoris muscle. In such cases, the rectus femoris muscle can be transposed to the knee flex- ors (gracilis or semitendinosus muscles) [10, 11, 22]. Less than 20% of knee extension force is lost as a result of this procedure, whereas knee flexion is improved by 10–20° in the swing phase. By contrast, injections of botulinum toxin into the rectus femoris muscle produce disappoint- ing results in our experience.
