Pcv-aCO_2联合ScvO_2指导胃癌术后补液的意义

Significance of Pcv-aCO_2 and ScvO_2 in guiding fluid rehydration after gastric carcinoma operation

目的探讨ScvO_2和Pcv-aCO_2对胃癌术后患者补液的指导意义。方法选取在我科行手术治疗的100例胃癌患者,随机分为试验组和对照组,各50例。试验组术后3 d常规抽取中心静脉及动脉血血气获取ScvO_2及Pcv-aCO_2值,对照组不做特殊处理。比较两组患者术后3 d补液量、输液相关的术后并发症。结果试验组术后3 d的补液量明显少于对照组,术后输液相关的并发症发生率明显低于对照组(P<0.05)。结论 Scv_O2及Pcv-aCO_2对指导胃癌术后患者补液有一定意义。

Objective To explore the significance of ScvO2 and Pcv-aCO2 in guiding fluid rehydration after gastric carcinoma operation. Methods One hundred patients with gastric cancer undergoing operation in our department were selected and randomly divided into experimental group（50 cases） and control group（50 cases）. The ScvO2 and Pcv-aCO2 values in the experimental group were obtained by extracting central venous and arterial blood gas at 3 d after operation. The control group was not treated specially. The volume of fluid rehydration in 3 d after operation and postoperative complications associated with transfusion were compared between the two groups. Results The volume of fluid rehydration in 3 d after operation in the experimental group was significantly less than that in the control group, the incidence rate of postoperative complications associated with transfusion was significantly lower than that in the control group（P〈0.05）. Conclusion The ScvO2 and Pcv-aCO2 values have significance to guide the fluid rehydration after gastric cancer operation.
