Abstract:
OBJECTIVETo investigate the protective effect of limited fluid resuscitation against intestinal ischemia- reperfusion injury in postpartum rabbits with severe uncontrolled obstetrical hemorrhagic shock.
METHODSTwenty- four postpartum rabbits were randomly assigned into sham shock group (group P), shock group without interventions (group P0), conventional fluid resuscitation group (group PNL), and limited fluid resuscitation group (group PLH), and the model of severe uncontrolled hemorrhagic shock was established in the latter 3 groups. The rabbits were sacrificed 4 h later, and SOD activity and MDA content in the intestinal mucosa and the degree of injury to the intestinal mucosa were observed.
RESULTSIschemia-reperfusion injury of the intestine due to uncontrolled hemorrhagic shock resulted in decreased SOD activity and increased MDA content. The MDA content was significantly lower and SOD activity was significantly higher in group PLH than in group PNL (P<0.05), and the intestinal mucosal tissue morphology and intestinal mucosa barrier lesion increased in group PLH.
CONCLUSIONInitial limited fluid resuscitation can relieve intestinal ischemia-reperfusion injury in postpartum rabbits with severe uncontrolled obstetrical hemorrhagic shock.
