The use of quantitative bacteriology in the burns unit has been thought to be efficient in predicting sepsis or graft loss. To examine the relationship between clinical outcome and bacterial densities on and in the burn wound, 69 biopsy/surface swab pairs were collected from 47 patients on 64 occasions, either immediately prior to excision and grafting, or at routine change of dressings. The mean per cent TBSA burn was 16 (range 1-65). ⋯ There was no significant difference in bacterial counts between patients judged to be a clinical success or clinical failure (72 h follow-up), either after undergoing excision and grafting, or change of dressings, and no difference in counts between patients with perioperative bacteraemia and those without. With burns > 15 per cent TBSA, a relationship between bacterial counts and subsequent sepsis or graft loss still was not demonstrated. It is suggested that quantitative bacteriology by burn wound biopsy or surface swab does not aid the prediction of sepsis or graft loss.

A method for preparing acellular allogeneic dermal matrix (ADM) and its effectiveness as a dermal substitute are described. Treatment of rat skin with Dispase followed by Triton X-100 completely removed cellular components from the dermis. Subcutaneously implanted ADM evoked no immunological reaction and 20 weeks after implantation, the size of the implanted ADM was reduced to about 60 per cent of its original area. ⋯ A second layer of ADM placed onto the implanted ADM served as an excellent dressing, providing mechanical protection and permitting vascularization of the underlying implant. Onlay skin autografts placed onto vascularized allogeneic ADM showed good survival when the skin was grafted more than 1 week after ADM implantation. Dispase/detergent treated ADM derived from animal or human skin may be useful in full thickness skin defects providing a vascularized bed for subsequent epidermal coverage.

Burn injury in pregnant patients is not uncommon in developing countries. The results of the management of six pregnant burns patients, admitted during an 18-month period, were analysed. Successful management of burn injuries ranging from 25 to 65 per cent TBSA occurred in patients during the second and third trimester of pregnancy, using early burn wound excision and skin grafting in four patients and by late skin grafting of a granulating wound in one patient. ⋯ One patient with 60 per cent TBSA burns who was unsuitable for early excision, died of septicaemia. This report suggests the need for early burn wound excision and skin grafting in burns patients with pregnancy, in order to improve maternal and fetal survival. However, in developing countries early surgery is not advisable in patients with extensive burns because of the non-availability of biological skin substitutes.

Burns are the fourth leading cause of injury death in children in the USA, accounting for 1300 paediatric deaths annually. The majority of paediatric burns mortality and morbidity result from simple domestic accidents that are preventable. A prospective study of paediatric burns from 1 January 1992 to 1 January 1993 was undertaken at our burns unit to outline the profile of the Irish paediatric burns problem. ⋯ Second, 90 per cent of the accidents occurred in the home and almost all were preventable. A parent or guardian was present in 87 per cent of cases but parental knowledge of the appropriate first aid measures was poor. It is suggested that a public health education campaign on this issue would help in reducing the incidence and severity of paediatric burn injuries in Ireland.

The use of patient-controlled analgesia with alfentanil (PCA-alfentanil) as a form of pain relief for dressing procedures in patients during the acute phase of their burn injuries was investigated. Five ASA 1 and 2 patients with 10-30 per cent total body surface area (TBSA) thermal burns, had PCA-alfentanil for their dressing procedures after standard fluid resuscitation. One patient who did not receive a loading dose and a background infusion of alfentanil had unsatisfactory pain relief. ⋯ One patient experienced nausea but no vomiting, no other adverse effects of alfentanil were noted. From the pilot study, PCA-alfentanil may be an effective form of pain relief for dressing procedures in patients during their acute phase of burn injuries. The optimal PCA-alfentanil setting has yet to be determined.
