Septicaemia in scald and flame burns: appraisal of significant differences.

One hundred and sixty burn patients suffering from septicaemia, hospitalized in the Al-Babtain Centre burns unit, Kuwait, between June 1992 and May 2001, were studied. Thirty-two patients (20%) had scalds and 128 (80%) flame burns, thus representing a ratio of 1:4 among septicaemic patients. There were 20 males (62.5%) in the scald group, compared to 73 (57%) with flame burns. Flame burns were significantly higher (p < 0.01) among non-Kuwaiti patients. The mean ages of the scald and flame burn patients were respectively 6.2 and 31.5 yr. The mean total body surface area burn in scalds was 20% and in flame burns 49%, which was significantly higher (p < 0.001). The 34 septicaemic episodes in 32 scald patients and 212 such episodes in 128 flame burn patients showed a significantly higher incidence in the latter group. The majority of septicaemic episodes, in scalds (82.4%) and flame burns (57.6%), were due to gram-positive organisms, mainly methicillin-resistant Staphylococcus aureus and methicillin-resistant Staphylococcus epidermidis. A significantly increased number of episodes were due to S. aureus (p < 0.001) and Enterococcus (p < 0.05) in scald patients. More surgical operations were performed in flame burn patients and survival increased significantly with an increasing number of grafting sessions (p < 0.001). The mean hospital stay in flame burn patients (56 days) was significantly higher than in scald patients (23 days) (p < 0.001). It is significant to record that all the 38 deaths (29.7%) were in flame burn septicaemic patients (p < 0.001). The scald and flame burn patients were quite distinct in their demographic and clinical characteristics. The flame burn patients were more vulnerable to septicaemia, with a high risk of mortality.
