目的探讨喉罩通气对颅内动脉瘤介入栓塞术患者循环系统的影响。方法 ASAⅡ~Ⅲ行颅内动脉瘤介入治疗患者40例,随机分为气管插管组(E组)和喉罩组(L组),均行全麻下控制通气。观察两组诱导前(T0)、气管导管(喉罩)置入前(T1)、置入后1 min(T2)、5 min(T3)、拔出前(T4)、拔出后2 min(T5)各时点的MAP、HR、SpO2、PETCO2。结果 E组在T2、T3、T4时MAP、HR比T1、T5明显升高(P<0.05),且明显高于同时间点L组(P<0.05);两组PETCO2、SpO2差异亦无统计学意义。结论行喉罩通气较气管导管通气在置入及拔出阶段引起的心血管反应小。
Objective To investigate the effect of laryngeal mask ventilation on the circulatory system in patients undergoing interventional embolization of intracranial aneurysms. Methods Forty patients with intracranial aneurysm interventional therapy ASA Ⅱ ~ Ⅲ were randomly divided into tracheal intubation group (E group) and laryngeal mask group (L group). All patients underwent controlled ventilation. The levels of T0, T1, T1, T2, T3, T4, T2 and T2 were measured before and after the laryngeal mask placement in both groups T5) MAP, HR, SpO2, PETCO2 at each time point. Results The MAP and HR of group E were significantly higher than those of T1 and T5 at T2, T3 and T4 (P <0.05), and were significantly higher than those of L group at the same time point (P <0.05). There was no statistical difference in PETCO2 and SpO2 Significance of learning. Conclusions The ventilation rate of laryngeal mask ventilation is smaller than that of tracheal catheter ventilation in the stage of insertion and extraction.
