目的观察腹腔压力增高对肾功能的影响。方法对60例腹腔间隙综合征患者,每日三次在固定时间检测患者腹腔压力,记录平均动脉压、中心静脉压,同时留取血液标本检测血清肌酐,记录每小时尿量。结果随着腹腔压力升高,尿量逐渐减少,由92.6±20 ml/h降至27.9±11.7 ml/h(P<0.05),同时血清肌酐由68.4±39.3mmol/L升至249.4±111.5 mmol/L(P<0.05),伴随中心静脉压(由1.34±0.25 kPa至2.12±0.22 kPaP<0.05),升高和平均动脉压升高或下降,腹腔压力的上升与尿量呈负相关(r=-0.193,P<0.05);与血清肌酐呈正相关(r=0.162,P<0.05),但与平均动脉压无相关性。结论腹腔压力的上升与少尿、血清肌酐上升密切相关;液体复苏、利尿剂的应用,对肾功能恢复效果不明显,而降低腹腔压力后,尿量增多、血清肌酐下降。
