摘要目的 探讨目标导向液体治疗对胃肠道手术患者围手术期液体管理及预后的影响.方法 选择全身麻醉下行胃肠道手术患者80例,按随机数字表法分为观察组和对照组,每组40例.对照组麻醉诱导后监测中心静脉压(CVP)指导输液治疗,使CVP在8～10mmHg(1 mmHg=0.133 kPa);观察组给予目标导向液体治疗,即监测每搏量变异(SVV)指导输液治疗,使SVV在10％～ 12％.记录两组手术时间、术中和术后3d液体管理情况;排气时间、排便时间、半流质或流质饮食时间,术后住院时间;术后48 h内并发症的发生率.结果 观察组术中输液总量、术中胶体液量、术中晶体液量明显少于对照组[(2 686.0±977.5)ml比(4 837.5±1 566.0) ml、(792.4±197.6)ml比(1 284.6±356.7) ml、(1 894.9±460.4) ml比(3 569.9±1 318.7) ml],差异有统计学意义(P＜0.05).观察组半流质饮食时间、术后住院时间明显短于对照组[(171.1±45.3)h比(235.8±89.5)h、(11.4±1.8)d比(14.7±4.9)d],差异有统计学意义(P＜0.05);两组排气时间、排便时间、流质饮食时间比较差异均无统计学意义(P＞0.05).两组术后并发症发生率比较差异无统计学意义(P＞ 0.05).结论 相对于CVP监测,胃肠道手术中给予目标导向液体治疗可以明显减少围手术期输液量,缩短术后住院时间.

abstractsObjective To explore the influence of fluid management and prognosis guided by goal direction on patients undergoing gastrointestinal surgery.Methods Eighty ASA grade Ⅰ-Ⅲ,consecutive consenting patients undergoing gastrointestinal surgery were divided into observation group (40 patients)and control group (40 patients) by random digits table method.The intraoperative fluid management in control group was based on central venous pressure(CVP),and kept CVP at 8-10 mmHg(1 mmHg =0.133 kPa).The intraoperative fluid management in observation group was based on stroke volume variation (SVV),and kept SVV at 10 ％-12％.The operation time,intraoperative and postoperative 3 d fluid management,time of defecation and exhaust,time of full or semi-liquid diet,length of stay in hospital,rate of complications after operation for 48 h between two groups were compared.Results The volume of total fluid,colloid solution and crystalloid solution received during operation in observation group were significantly lower than those in control group[(2 686.0 ± 977.5) ml vs.(4 837.5 ± 1 566.0) ml,(792.4 ± 197.6) ml vs.(1 284.6 ± 356.7)ml,(1 894.9 ± 460.4) ml vs.(3 569.9 ± 1 318.7) ml] (P ＜ 0.05).The time of semi-liquid diet,length of stay in hospital in observation group were significantly lower than those in control group [(171.1 ± 45.3) h vs.(235.8 ±89.5) h,(11.4 ±1.8) d vs.(14.7 ±4.9) d] (P＜0.05).The time of full liquid diet,time of defecation and exhaust between two groups had no significant difference(P ＞ 0.05).The rate of complications between two groups had no significant difference(P ＞ 0.05).Conclusion Compared with monitoring CVP,the fluid management based on SVV can decrease the fluid volume during operation and shorten the length of stay in hospital.
