目的蛛网膜下腔出血栓塞术后呼气末正压对其腹腔压力的影响。方法选取蛛网膜下腔出血介入栓塞术后行机械通气的24例患者,在容量控制通气(Volume A/C)的通气模式下,观察呼气末正压(PEEP)的变化对腹腔压力的影响。结果在Volume A/C模式下,当PEEP=0 cm H_2O时,腹腔压力测定值与基线值比较差异无统计学意义(P>0.05),但是随着PEEP的增加,PEEP 6~12 cm H_2O时,腔压力随之升高(P<0.05)。结论蛛网膜下腔出血介入栓塞术后患者在机械通气状态下,呼气末正压的变化将会对腹腔压力产生显著影响。
Objective To investigate the effect of positive end-expiratory pressure on intraperitoneal pressure after subarachnoid hemorrhage and embolization. Methods Twenty-four patients undergoing mechanical ventilation after subarachnoid hemorrhage were enrolled in this study. The effects of changes in positive end-expiratory pressure (PEEP) on abdominal pressure were observed under volume-controlled ventilation (Volume A / C) . Results In Volume A / C mode, when PEEP = 0 cm H_2O, there was no significant difference between baseline and measured values of abdominal pressure (P> 0.05). However, with the increase of PEEP, PEEP of 6 ~ 12 cm H_2O , Lumen pressure increased accordingly (P <0.05). Conclusions Patients with subarachnoid hemorrhage after interventional embolization in mechanical ventilation, the change of positive end expiratory pressure will have a significant impact on abdominal pressure.
