Evaluation of cellular and biochemical parameters of blood and peritoneal fluid following exploratory laparotomy in the goat.

To evaluate the effects of exploratory laparotomy on cellular and biochemical parameters of blood and peritoneal fluid, an experiment was conducted using 10 Iranian cross-bred male goats. Approximately 10 ml of blood and 1-1.5 ml of peritoneal fluid were collected from all animals prior to operation for estimation of control values. Exploratory laparotomy was performed under local analgesia. Blood and peritoneal fluid samples were collected at 24, 48, 72 and 96 h after exploratory laparotomy. The results revealed that after exploratory laparotomy, the number of white blood cells and the percentage and absolute number of neutrophils and band neutrophils significantly increased (P < 0.05). However, the percentage of lymphocytes decreased significantly (P < 0.05). The concentrations of blood urea nitrogen significantly increased (P < 0.05). Furthermore, following the operation, the percentage and absolute number of neutrophils in the peritoneal fluid significantly increased (P < 0.05). In contrast, the percentage of lymphocytes in the peritoneal fluid decreased significantly (P < 0.05). The concentration of protein in the peritoneal fluid increased significantly (P < 0.05).
