Severe thermal hand burns--factors affecting prognosis.

This paper presents the results of the analysis of clinical data from a series of 132 thermally injured patients with 214 burned hands. The objective was to identify the factors affecting the pathogenesis of postburn hand deformities. The study indicates that deep burns have the worst prognosis and that circumferential burns are always followed by secondary sequelae. The incidence of secondary hand deformity rises sharply when the burn affects more than 25 per cent of the total body surface area (TBSA). Given the same physical therapy programme, early tangential excision and immediate grafting yield better results than conservative treatment. The results underline the role of patient motivation in maximal hand rehabilitation.

Early excision of full-thickness hand and digit burns: factors affecting morbidity.

Full-thickness dorsal hand and digit burns result in serious acute and chronic functional disability. Early wound closure is paramount to minimize functional impairment and improve ultimate cosmetic appearance. Fifty patients were followed for 2 to 6 years after excision and immediate autografting of full-thickness hand and digit burns. Based on the depth of injury distal to the metacarpal phalangeal joints, two groups of hand burns emerged in this series. Group I: Patients had uninjured and intact extensor mechanisms. Near normal range of motion was obtained by the end of the second postoperative week. Local wound sepsis and/or inadequate depth of excision resulted in autograft loss and additional surgical procedures in 10% of the hands. Group II: Patients with thermal damage to some portion of the extensor mechanism of the digit. Seventy-five per cent of these hands had thermal damage to bone. An average of three operative procedures was required on each hand for ultimate wound closure. Prolonged immobilization, persistent edema, and local wound sepsis were common to all Group II hands. Reconstructive surgery was necessary within 1 year in 43% of all hands. Hands in Groups I and II required surgery 12% and 75% of cases, respectively. Early surgical excision coupled with aggressive physical and occupational therapy has decreased but not eliminated many of the acute and chronic sequelae of full-thickness hand and digit burns.

Acute electric burns. Current diagnostic and therapeutic approaches to management.

A review of 102 cases of high-voltage electric injuries was performed. The average total body surface area was 15.2%. The average age was 32 years. The mortality was 2.1%. Advances in fluid therapy have virtually eliminated renal failure. Devitalized muscle was accurately identified preoperatively with the use of the technetium Tc 99m pyrophosphate muscle scan. Septic complications were reduced substantially by using the following therapeutic modalities: early excision of the burn eschar and necrotic muscle; quantitative wound biopsies to monitor the bacterial flora; allograft as a temporary coverage of open wounds; and early creation of local and distant flaps. Early institution of physical and occupational therapy are mandatory if the patient is to be restored to his or her maximum postinjury potential.

Results of phalloplasty.

We present our experience with a method of phalloplasty which can be applied by reconstructive surgeons to cases of penile loss from diverse etiologies. The complications with this method have been frequent, but not life-threatening. Achievement of the stated objectives is obtained in a sufficiently high proportion of cases to make this a method whorthwhile to use until a clearly superior method can be demonstrated.

Hetastarch: an alternative colloid in burn shock management.

Hetastarch is a synthetic polysaccharide colloid that has been used clinically in the management of multiple trauma, hypovolemic shock, and postoperative cardiac patients. Our objective was to determine whether hetastarch is a safe alternative to blood products in burn shock resuscitation. Twenty-six patients received hetastarch during the colloid phase of resuscitation and were compared to matched historical controls who received either albumin or fresh frozen plasma. Clinical and laboratory parameters were measured on admission and for 4 days after the burn. There was no significant difference in hemodynamics, respiratory status, incidence of bleeding, or renal or liver function among the three colloid groups. The advantages of hetastarch include immediate availability, no dependence on human blood donor population, no risk of serum-transmitted diseases, and lower cost. It can be safely recommended for those patients who object to blood products for resuscitation, in those situations where human donors are few, and when cost is a consideration.
