摘要 目的 探讨连续性静脉-静脉血液滤过透析(CVVHDF)和局部枸橼酸抗凝在重症患者乳酸升高时应用的有效性和安全性。方法 选取本院收治的重症伴乳酸升高患者82例,均给予连续性静脉-静脉血液滤过透析,根据抗凝方式的不同将患者分为对照组(n=42,普通肝素全身抗凝)和研究组(n=40,局部枸橼酸抗凝治疗),比较两组治疗前后乳酸水平,治疗后滤器平均使用寿命、透析器及管路凝血情况、并发症发生情况。结果 治疗前,两组乳酸水平水平对比无明显差异(P>0.05),治疗后,实验组乳酸水平明显低于对照组(P<0.05);研究组滤器使用寿命明显长于对照组(P<0.05);虽然研究组总体透析器及管路凝血事件高于对照组,但该组并未发生Ⅱ级及以上的凝血事件;而对照组发生6例Ⅱ级及以上的凝血事件,两组透析器及管路凝血严重程度及发生率对比(P<0.05)。两组患者并发症发生率对比,差异无统计学意义(P>0.05)。结论 局部枸橼酸抗凝在连续性静脉-静脉血液滤过透析治疗重症患者乳酸升高时的有效性与可行性优于普通肝素,尤其在滤过寿命方面优势更大,且不会增加枸橼酸蓄积和相关代谢并发症发生风险,但治疗期间仍需密切监测体患者体内钙和凝血参数的变化,防止意外发生。
