Abstract： 目的观察连续性血液净化(CBP)对重症急性胰腺炎(SAP)患者胃黏膜酸度的影响.方法选择SAP患者20例,随机分为CBP治疗组和非CBP治疗对照组各10例,两组均在治疗前、治疗第2天、4天和6天测定其胃黏膜pH值(pHi)及动脉血乳酸值.结果两组患者初始pHi均值均偏低,CBP组患者治疗后第4天和第6天pHi水平较治疗前明显升高,且差异有显著性(分别为P＜ 0.05和P＜ 0.01),对照组治疗前后pHi水平未见显著改变.两组间比较,治疗第4天和第6天,CBP组pHi水平显著高于对照组(分别为P＜ 0.05和P＜ 0.01).CBP组在治疗第2天乳酸值即开始显著下降(P＜ 0.05),治疗第6天乳酸值下降最为显著(P＜ 0.01);对照组治疗前后乳酸值无显著改变(P > 0.05);与对照组比较,治疗后第2天和第4天CBP组乳酸水平显著降低(P＜ 0.05),第6天降低最为明显(P＜ 0.01).结论应用CBP治疗可提高SAP患者pHi,并降低患者乳酸代谢水平,改善患者胃肠道的微循环灌注及氧合.
