摘要 目的:观察西沙必利对大鼠失血性休克复苏后的肠屏障功能的影响.方法:108只Wistar大鼠随机分为假休克(SS)组、失血性休克复苏(HS)组和失血性休克复苏后西沙必利治疗(HSC)组,染料法测定肠道传输,同位素标记生物微球法测量肠道血流量,应用荧光素异硫氢酸葡聚糖(FITC-D)和辣根过氧化酶(HRP)Ⅱ型两种分子探针测定小肠通透性,同时观察肠腔内细菌繁殖和腹腔内脏器细菌移位.结果:HSC组与HS组相比,肠道传输增快,肠道血流量增加,肠腔中细菌量减少,空肠和回肠通透性降低,2h肠系膜淋巴结、4h肝中细菌量明显降低(P<0.05或P<0.01).结论:失血性休克复苏后,早期应用西沙必利,可促进肠道传输,有助于改善肠道血液循环,从而改善肠屏障功能.
