Central line-related sepsis in acute burn patients.

A retrospective review of all 443 burn patients admitted during a 13-month period from October 1, 1992 to October 31, 1993, was completed. Of these, 8 were transferred and eliminated from the study. Twenty-two patients who were felt to be terminal on admission and did not have blood cultures were included in the demographic data but were excluded from subsequent statistical analysis. One hundred ten patients had central venous lines (CVLs). Three patients with CVLs were transferred, thus leaving 107 patients with CVLs for statistical analysis. Additionally, 17 of the aforementioned terminal patients who had CVLs and 1 patient with a CVL who had documented sepsis before CVL insertion were excluded, leaving 89 patients with CVLs used in statistical analysis. Mean burn surface for those with central lines was 35.8 per cent, and for those without, 10.9 per cent. Sixty-four patients (59.8%) with a central line had inhalation injuries, as did 18 patients (5.5%) without. The number of lines per patient varied from 1 to 7. Sixty-one patients had one line, 46 had more than one. The total number of central line days for the entire group was 1749. The mean number of central line days per patient was 16.3. The mean number of line days per catheter was 8.48. The mortality rate for the 107 patients with a central line was 34 (32.7%). Mortality for all patients was 41 (9.4%). The incidence of sepsis increased with increasing number of central line days and increasing number of central line changes, but the effect of these two factors on the incidence of sepsis could not be studied separately, as they are highly correlated with each other. The most commonly recovered organisms were various types of Staphylococcus. Polymicrobial infections were common. There were 51 subclavian, 17 internal jugular, and 135 femoral catheters inserted. By logistic regression analysis, there was no statistically significant difference in the incidence of sepsis between upper- and lower-body CVL sites. Twenty-four patients (22.4%) with a CVL and one or more positive blood cultures were felt to have demonstrated sepsis. Some had more than one septic episode while lines were in place, reported as separate patients but not as separate septic episodes.

Primary excision of the burn wound.

Early excision of burn eschar and wound closure significantly improves survival following major burn injury. Immediate primary excision performed by burn-experienced surgeons in dedicated burn care facilities can reduce further morbidity and mortality, length of hospital stay and medical costs. Burn care at the millennium is evolving rapidly into a subcategory of trauma surgery, with burn patients increasingly being viewed as victims of major trauma who benefit most from immediate and definitive surgical correction of their injuries.

Trichosporon beigelii septicaemia in a burn patient.

A patient with Trichosporon beigelii sepsis secondary to a 31 per cent burn is reported. Good results were obtained by treatment with amphotericin B. No other reports of septicaemia due this organism in burn patients have been found by us, although the organism has been reported as a cause of sepsis in cancer patients.

An approach to the management of toxic epidermal necrolysis in a burn centre.

Toxic epidermal necrolysis syndrome, a life-threatening skin disorder, requires specialized nursing care to optimize survival. The similarity of the condition to partial skin thickness burns suggests that management on a burn unit is an effective means of therapy. A review of eight patients treated at our Burn Center emphasizes the need for aggressive team management of the condition.

Experience with polymicrobial sepsis in a regional burn unit.

A 2-year review of 795 patients admitted to a regional burn unit was carried out to determine the incidence of polymicrobial sepsis. Of 38 bacteraemic patients, 21 (55 per cent) had polymicrobial sepsis in 1990. Of 38 cases in 1991, 12 patients (31.6 per cent) had polymicrobic infections. Of 36 deaths in 1990, 13 were attributed to sepsis, 12 of 29 (31.6 per cent) in 1991. Of the patients who died in 1990, eight (21 per cent) were polymicrobic septic deaths and six (15.8 per cent) in 1991. The problem has been reported in immunocompromised patients, especially those with terminal malignancies, but has rarely been noted in burn patients. Recognition of the seriousness of the problem and the aggressive antibiotic therapy appropriate to the organisms in question is advised.

Management of candida septicaemia in a regional burn unit.

Sepsis due to candida infection is a major cause of mortality and morbidity on our unit. Over a period of 3 years and 4 months, 29 cases of candida septicaemia, diagnosed by blood cultures, were encountered at the burn unit at Augusta Regional Medical Center. Factors known to predispose to fungal sepsis were present in all cases. All patients had large burns (14-98 per cent total body surface (TBSA) with a mean of 48.3 per cent). All but one patient had at least one central venous line. Respiratory problems requiring ventilator support were present in 24 patients. Sixteen patients had Candida albicans sepsis, two in association with another fungal sepsis. Candida parapsilosis was encountered in nine patients, one in combination with another species. Four patients had Candida tropicalis. Amphotericin B was prescribed therapeutically in 25 patients, in seven together with fluconazole. Two patients received fluconazole only and two received no antifungal therapy. There were eight deaths all attributed to sepsis and all of whom had multiple organ failure. Five of those who died had completed a course of amphotericin B therapy, two were receiving treatment at the time of death, and one patient died before culture data became available. Early and aggressive therapy is advised and amphotericin B appears to be the drug of choice.

Massive haemorrhage due to rectosigmoid ulcers in a patient with extensive burns.

A 36-year-old white-skinned male was admitted with 45.5 per cent burns, mostly of full skin thickness. Severe rectal bleeding from rectal ulcerations developed on postburn day 12. Various conservative attempts at management failed, and after multiple transfusions, abdominoperineal resection was carried out with eventual complete recovery. Complications during his acute phase included Pseud. aeruginosa sepsis and Clostridium difficile diarrhoea. Extensive skin grafts were required. The cause of the rectal ulcerations is unclear.

The use of erythropoietin in two burned patients who are Jehovah's Witnesses.

Recombinant-human erythropoietin was given to two burn patients who are Jehovah's Witnesses and hence refused transfusion. Anaemia developing postburn was corrected in both patients. Serum erythropoietin levels were found to be elevated prior to initiation of therapy in both patients.

Caecal perforation due to colonic ulcer in a burn patient.

Non-specific ulcers of the colon are occasionally reported as a cause of perforation of the colon. No previous cases have been reported in burn patients as a cause of perforation, although cases of haemorrhage have been cited. A 42-year-old black-skinned female with a 26 per cent TBSA burn developed a caecal perforation from this cause. Treatment with caecostomy patient recovered successfully.

Invasive burn wound infection due to Curvularia species.

A 3-year-old white-skinned female sustained a 44 per cent deep partial and full skin thickness burn due to petrol. She developed an invasive wound infection due to a fungus later identified as Curvularia species, an organism, usually a saprophyte, not previously reported as a cause of invasive burn wound infection. Treatment with surgical excision and Amphotericin B resulted in cure.
