目的:观察家兔腹部手术后肠蠕动功能的变化。方法:30例家兔随机分为正常对照组、假手术组、模型组,胃肠减压、禁食、全麻后行肠切除肠端吻合术,观察各组动物血浆中胃肠激素:生长抑素(SS)、P物质(SP)、胃动素(MOT)、血管活性肠...目的:观察家兔腹部手术后肠蠕动功能的变化。方法:30例家兔随机分为正常对照组、假手术组、模型组,胃肠减压、禁食、全麻后行肠切除肠端吻合术,观察各组动物血浆中胃肠激素:生长抑素(SS)、P物质(SP)、胃动素(MOT)、血管活性肠肽(VIP)、小肠推进率及小肠肌电(BER)变化情况。结果:假手术组3 h BER低于正常对照组(P〈0.05),6-48 h BER与正常对照组比较无明显差异(P〉0.05);模型组BER、小肠推进率及血浆中胃肠激素水平均低于对照组(P〈0.05,P〈0.01)。结论:腹部手术后小肠蠕动功能受到抑制,胃肠激素分泌改变。展开更多
