[source] Bacteriotherapy with Lactobacillus plantarum in burnsINTERNATIONAL WOUND JOURNAL, Issue 1 2009Maria C Peral Abstract Bacterial colonisation and infection remain the major causes of delayed healing and graft rejection following burns. Topical treatment is necessary to reduce the incidence of burn wound infection. Silver sulphadiazine (SD-Ag) is an often used microbicidal agent. However, this treatment produces adverse reactions and side-effects. On the basis of experimental data and clinical application of lactobacilli as probiotics, we performed this exploratory study to establish the effectiveness of bacteriotherapy with topical application of the innocuous bacteria Lactobacillus plantarum cultured in De Man, Rogosa and Sharpe medium to provide an alternative method for burn treatment using SD-Ag as a reference. These innocuous bacteria would compete with other bacteria that are wound pathogens and would modify the wound environment and promote tissue repair. Eighty burned patients from the Plastic Surgery and Burns Unit were grouped into infected (delayed) second- and third-degree and non infected (early) third-degree burns and treated with L. plantarum or SD-Ag. The proportion of patients with delayed second-degree burns was 0·71 for L. plantarum and 0·73 for SD-Ag (relative rate: ,2·72%) with respect to the decrease in bacterial load (<105 bacteria/g of tissue), promotion of granulating tissue wound bed and healing. In early third-degree burns, the values were 0·75 for L. plantarum and 0·84 for SD-Ag (relative rate: ,1·07%) in preventing wound infection and promotion of granulation tissue, 0·90 in graft taking for both treatments (relative rate: 0%) and 0·75 for L. plantarum and 0·77 for SD-Ag (relative rate: ,2·60%) in healing. In delayed third-degree burns, values were 0·83 for L. plantarum and 0·71 for SD-Ag (relative rate: +16·90%) with respect to the decrease in the bacterial load (<105 bacteria/g of tissue) and providing a granulating tissue wound bed, 0·90 in graft taking for both treatments (relative rate: 0%) and 0·75 for L. plantarum and 0·64 for SD-Ag (relative rate: + 17·19%) in healing. Although the number of patients (between 12 and 15 per group) did not enable the application of a power statistical test, these results suggest that the L. plantarum treatment should be studied in greater depth and could be used as a valid alternative for the topical treatment of burns. [source] The effects of ketamine and propofol on bacterial translocation in rats after burn injuryACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 2 2005H. Yagmurder Background:, Bacterial translocation (BT) occurs after thermal injury and may result from an ischemic intestinal insult. The aim of the study was to investigate the effects of ketamine and propofol as anesthetic agents on BT in an animal model of burn injury. Methods:, Sixty male Wistar Albino rats were randomly assigned to six groups of 10 rats each. Anesthesia was induced and maintained with ketamine in groups 1, 2 and 3 and with propofol in groups 4, 5 and 6 during 6 h. Groups 2, 3, 5 and 6 received 30% total body surface area (TBSA) third-degree burns. Groups 1 and 4 had no burn injury. Then, they were allowed to recover from the anesthesia at the end of 6 h. Mean arterial pressure (MAP) was monitored continuously and maintained within 10% of baseline (before burn injury) levels in all animals. Animals in groups 3 and 6 had a laparotomy to obtain a tissue sample from the terminal ileum for determination of intestinal lipid peroxidation by-product malondialdehyde (MDA) before (baseline) and 6 and 24 h after burn injury (ABI). So these animals were not included in the BT studies. At postburn 24 h, animals in groups 1, 2 and 4, 5 were sacrified and samples were taken from the mesenteric lymph nodes (MLN), liver and spleen for bacteriologic cultures. Results:, The incidence of BT was found to be significantly higher in group 2 than in all the other groups. Bacterial translocation incidence of group 5 was not significantly different from that of groups 4 and 1. Group 5 was associated with a significantly reduced number of enteric organisms per gram of tissue compared to group 2. Baseline MDA contents of groups 3 and 6 were similar. Ileal MDA levels were increased in group 3, but there were no significant changes in group 6 at 6 and 24 h ABI compared to baseline. Conclusion:, Our results suggest that propofol as an anesthetic agent may prevent BT by scavenging reactive oxygen species and inhibiting lipid peroxidation in an animal model of burn injury.
