早期小剂量糖皮质激素对脓毒症休克患者血流动力学及预后的影响

目的 探讨早期应用小剂量糖皮质激素对脓毒症休克患者血流动力学及预后的影响.方法 选择2013年6月至2015年8月该院脓毒症休克积极液体复苏及血管活性药无效的患者60例,分为对照组及早、晚期激素治疗组,患者均于治疗前及治疗后12、24、48 h监测平均动脉压(MAP)、心率(HR)、氧合指数(PO2/FIO2)及血乳酸水平;患者均于治疗前及治疗后1、3、7d进行急性生理与慢性健康状况评分Ⅱ(ApacheⅡ)、序贯器官衰竭估计(SOFA)评分;记录各组患者机械通气时间、住ICU时间、住院时间及血管活性药物静脉使用时间(VDUT).结果 早治疗组治疗后3、7 d ApacheⅡ、SOFA评分均较对照组及晚治疗组明显下降(P＜0.05);早治疗组治疗后24、48 h患者MAP、HR均较晚治疗组和对照组明显好转(P＜0.05);早、晚治疗组治疗后12、24 h血乳酸水平均较对照组明显下降,早治疗组血乳酸水平均较晚治疗组明显下降(P＜0.05);早、晚治疗组治疗后12、24、48 h PO2/FIO2均较对照组明显改善;早治疗组治疗后12 h PO2/FIO2较晚治疗组明显改善(P＜0.05);早治疗组机械通气时间、住ICU时间、住院时间及VDUT均较晚治疗组和对照组明显缩短;晚治疗组机械通气时间、住ICU时间及VDUT均较对照组明显缩短(P＜0.05).结论 早期应用小剂量糖皮质激素可以更快地恢复脓毒症休克患者的血流动力学,保护脏器功能并改善患者的预后.

Effect of early low-dose glucocorticoid on hemodynamics and prognosis in patients with septic shock

Objective To investigate the effect of early low-glucocorticoid on hemodynamics and prognosis in the patients with septic shock.Methods Sixty patients with septic shock failing in active fluid resuscitation and vasoactive drugs in our hospital from June 2013 to August 2015 were selected and divided into the control group,early-hormone group and late-hormone group.MAP,HR,PO2/FIO2 and serum lactic acid levels were monitored in all selected patients before treatment and at 12,24,48 h after treatment.Apache Ⅱ,SOFA scores were assessed before treatment and on 1,3,7 d after treatment.The ventilation time,ICU stay time,hospital stay time and intravenous use time of vasoactive agents(VDNT) were recorded.Results The Apache Ⅱ scores and SOFA scores on 3,7 d after treatment in the early-hormone group were significantly decreased compared with the late-hormone group and control group (P＜0.05).MAP and HR at 24,48 h after treatment in the early-hormone group were significantly improved compared with the late-hormone group and control group (P＜0.05).The level of serum lactic acid at 12,24 h after treatment in the early-hormone group and late-hormone group were obviously lower than that in the control group,the levels of serum lactic acid at 12,24 h after treatment in the early-hormone group were obviously lower than those in the late-hormone group (P＜ 0.05).PO2/FIO2 at 12 h after treatment in the early-hormone group and late-hormone group were obviously better than that in the control group,and PO2/FIO2 at 12 h after treatment in the early-hormone group was obviously better than that in the late-hormone group(P＜0.05).The ventilation time,ICU stay time,hospital stay time and VDUT in the early-hormone group were significantly shortened compared with the late-hormone group and control group.The ventilation times,ICU stay time and VDUT in the latehormone group were significantly shortened compared with the control group (P＜0.05).Conclusion Early using low-dose glucocorticoid may restore hemodynamics more quickly,protects the organ function and improves the prognosis in the patients with septic shock.
