The Effect of Peritoneal Prednisolone Lavage in Bacterial Peritonitis: An Experimental Study.
OBJECTIVE: This study investigated and compared the effects of antibiotic and steroid lavage on survival and cytokine levels in an experimental abdominal sepsis model.
BACKGROUND: In abdominal sepsis, abdominal lavage with saline or antibiotic solutions is a well-documented intervention known to have positive impact on survival; however, the effects of steroid lavage in abdominal sepsis have not yet been investigated.
MATERIALS AND METHODS: Ninety-six Wistar rats were divided into 4 groups (n = 24). Abdominal sepsis was induced by cecal ligation and puncture. Six hours after laparotomy, the authors performed a relaparatomy followed by cecal resection and an abdominal lavage. Abdominal lavage was performed using saline in group 1, equal volumes of cefazolin sodium in group 2, low-dose methylprednisolone (1 mg/kg) in group 3, and high-dose methylprednisolone (2 mg/kg) in group 4. After division of 2 subgroups from each of the 4 groups, the first of the rats (n = 12) were euthanized 6 hours later for evaluation of cytokines (ie, interleukin [IL] 1β, 2, 4, 10, and tumor necrosis factor alpha [TNF-α]), and the others were followed for 30 days for analysis of mortality rates.
RESULTS: The mortality rate of the rats in group 2 was significantly higher than group 4, which had no mortality (P = 0.032). Although insignificant, the lowest mean value of IL-1β, IL-2, and TNF-α were in group 1, and the highest was in group 2. The lowest IL-4 level was in group 3, and the highest level was in group 2 (P = 0.41). Interleukin-10 levels were significantly lower in group 4 and higher in group 2 (P = 0.014).
CONCLUSION: The authors state that peritoneal lavage with prednisolone improved survival rates with increasing doses in abdominal sepsis.
