目的探讨每搏量变异度(SVV)监测液体复苏治疗感染性休克患者的效果。方法选取该院ICU 2015年10月至2016年10月收治的感染性休克患者78例,均行液体复苏治疗,随机分为监测中心静脉压(CVP)组38例与SVV组40例,比较两组监测效果。结果 SVV组补液量为(3 740.8±218.6)ml,明显少于CVP组,差异有统计学意义(P<0.05);两组补液后CVP、SVV、平均动脉压(MAP)、心脏指数(CI)及心率(HR)与自身补液前相比均有明显效果,差异有统计学意义(均P<0.05);SVV组补液后SVV与CVP水平与CVP组对比,差异有统计学意义(P<0.05);SVV组水肿发生率为15.0%,低于CVP组47.4%,差异有统计学意义(P<0.05)。结论液体复苏治疗时监测SVV可准确、可靠反映患者的容量状态,在指导治疗感染性休克患者中临床价值较高。
Objective To investigate the effect of stroke volume variation (SVV) monitoring of fluid resuscitation in patients with septic shock. Methods Seventy-eight patients with septic shock admitted to ICU from October 2015 to October 2016 in our hospital were enrolled in this study. They were randomly divided into three groups: 38 for central venous pressure (CVP) and 40 for SVV Group monitoring results. Results The rehydration volume of SVV group was (3 740.8 ± 218.6) ml, which was significantly lower than that of CVP group (P <0.05). CVP, SVV, MAP, ) And heart rate (HR) were significantly higher than those before rehydration (all P <0.05). The SVV and CVP levels in SVV group were significantly higher than those in CVP group (P < 0.05). The incidence of edema in SVV group was 15.0%, which was lower than that in CVP group (47.4%), the difference was statistically significant (P <0.05). Conclusion Surveillance of SVV during fluid resuscitation can accurately and reliably reflect the volume status of patients and has a high clinical value in guiding the treatment of septic shock.
