title: [Effect of peritoneal lavage with povine-iodine on prevention of postoperative sepsis after exposure of peritoneal cavity to sea water in rat].
abstract: OBJECTIVE
  To observe the effects of peritoneal lavage with povine-iodine on prevention of sepsis after exposure of peritoneal cavity to sea water in rat.
  
  
  METHODS
  Eighty-four SD rats were randomly divided into two groups, and the peritoneal cavity was exposed to sea water. Rats in group A were not treated (group A, n=42), and the peritoneal cavity was lavage with povine-iodine in group B (n=42). Plasma levels of endotoxin and tumor necrosis factor (TNF) were measured preimmersion, and 0, 12, 24 hours after seawater immersion (n=6), and positive incidence of blood bacterial culture was performed (n=18 in each group) in groups A and B.
  
  
  RESULTS
  1. Plasma levels of endotoxin and TNF in group A and B were increased significantly after exposure of peritoneal cavity to sea water (compared with baseline values, all P<0.05). Plasma levels of endotoxin and TNF in group B became lower than those in group A from 12 hours after seawater immersion (P<0.05 or P<0.01). 2. Positive incidence of bacterial culture in group B was 16.7 % (3/18) and it was lower than that in group A (77.8 % (14/18), P<0.01).
  
  
  CONCLUSIONS
  Povine-iodine lavage in the peritoneal cavity can reduce levels of plasma endotoxin and TNF, and lower positive incidence of bacterial culture in rats after exposure of peritoneal cavity to sea water, thereby preventing the development of postoperative sepremia.
