目的:研究脉搏灌注变异指数在严重创伤患者容量治疗中的应用。方法:选择2012年3月至2015年4月,在江门市新会区第二人民医院急诊科就诊的严重外伤患者31例,监测补液试验前后患者的心率(HR)、收缩压(SBP)、舒张压(DBP)、平均动脉压(MAP),中心静脉压(CVP)、心指数(CI)、每搏量变异(SVV)和脉搏灌注变异指数(PVI)等指标。补液试验后,以CI增加≥15%为对容量治疗有反应组,否则为无反应组。结果:31例患者,男性23例,女性8例;有反应组在补液试验前的基础HR、SBP、DBP、MAP、CVP较无反应组无统计学差异,而有反应组的CI、SVV、PVI均明显高于无反应组(P<0.05);有反应组补液试验后,CVP、CI、SVV和PVI变化具有显著统计学意义(P<0.05)。结论:PVI可反映机体的容量状态,可用于监测机体对容量治疗的反应性。
Objective: To study the application of pulse perfusion index in the treatment of patients with severe trauma. Methods: From March 2012 to April 2015, 31 patients with severe traumatic injury admitted to Emergency Department of Second People’s Hospital of Xinhui District, Jiangmen City were enrolled in this study. Heart rate (HR), systolic blood pressure (SBP) DBP, MAP, CVP, CI, SVV and PVI were measured. Rehydration test to CI increase ≥ 15% for the volume of treatment response group, otherwise non-response group. RESULTS: There were 31 patients, 23 males and 8 females. The baseline HR, SBP, DBP, MAP and CVP in the response group before rehydration test were not significantly different from those in the non-response group, while those in the response group were CI, SVV, PVI were significantly higher than the non-reaction group (P <0.05); CVP, CI, SVV and PVI changes in the response group after rehydration test was statistically significant (P <0.05). Conclusion: PVI can reflect the capacity of the body state, can be used to monitor the body’s response to capacity therapy.
