丙酮酸盐替代乳酸盐腹膜透析液腹腔复苏对失血性休克家兔肠黏膜屏障的影响
Effect of pyruvate replacing lactate dialysis solution peritoneal resuscitation on intestinal mucosal barrier of rabbit with hemorrhagic shock
摘要
Abstract
Objective To observe the effects of peritoneal resuscitation by pyruvate replacing lactate peritoneal dialysis solution on the intestinal mucosal barrier in rabbits with hemorrhagic shock.Methods The hemorrhagic shock model was prepared in 48 healthy male rabbits by adopting the improved Wiggers method.Then the rabbits were randomly divided into the conventional intravenous resuscitation group (group A),conventional intravenous resuscitation plus intraperitoneal injection of lactate peritoneal dialysis solution group (group B),conventional intravenous resuscitation plus intraperitoneal injection of pyruvate peritoneal dialysis solution group (group C) and intravenous pyruvate peritoneal dialysis solution resuscitation plus intraperitoneal injection of pyruvate peritoneal dialysis solution group (group D).The levels of diamine oxidase (DAO) and lipopolysaccharide (LPS) were measured before shock,at 60 min after shock,at 60,180 min after resuscitation.At the end of observation,the ileum tissues were taken from the 5 cm away from the ileocecal region for measuring the dry/wet ratio,malondialdehyde (MDA) level and superoxide dismutase (SOD) activity and their morphological changes was observed.Results There was no statistical difference in the plasma levels of DAO and LPS before shock among the four groups (P＞0.05);which at 50 min after shock were increased,but the comparison among the groups had no statistical difference (P＞0.05);the plasmas levels of DAO and LPS at 60,180 min after resuscitation in the group A,B,C and D were decreased in turn (P＜0.05).The MDA levels of ileum tissues after 180 min of resuscitation in the group A,B,C and D were decreased in turn (P＜0.05),but the SOD activties and tissue dry/wet mass ratios were increased in turn (P＜005),moreover the tissue injury degrees were also relieved in turn.Conclusion The peritoneal resuscitation by pyruvate replacing lactate peritoneal dialysis solution can more effectively protect the intestinal tissue cells and reduce intestinal mucosal damage in hemorrhagic shock rabbits.关键词
