Abstract
Fibrin gel (FG) has recently been shown to be bactericidal in the management of contaminated hepatic injury; antibiotic loading of fibrin gel (AFG) may augment this effect. We evaluated the antimicrobial properties of FG and AFG in a rat model of contaminated splenic injury. Fibrin gel was made from centrifuged plasma of separate donor rats and bovine thrombin. Antibiotic fibrin gel was similarly produced following intravenous injection of 70 mg/kg ticarcillin. Male Holtzman rats (250-300 g) were anesthetized and a laparotomy done. The abdomen was contaminated with 1 x 10(7) Bacteroides fragilis and the spleen transected in the midportion. Treatment consisted of splenorrhaphy (S) (n = 7), FG application (n = 7), or AFG (n = 7). The animals were autopsied at 1 week to evaluate abscess formation and abdominal adhesions (grade I = none, grade II = mild, grade III = severe). Antibiotic/fibrin gel significantly decreased abscess formation following splenic injury when compared with S (2 of 7 vs. 7 of 7; p less than 0.05 by ANOVA) without an increase in adhesions. Fibrin gel also decreased abscess formation but not significantly (4 of 7 vs. 7 of 7). Histologic analysis confirmed the beneficial effect of FG and AFG on wound healing. The bactericidal effect of FG is improved by antibiotic loading in contaminated intraabdominal injury.
