目的观察可充气喉罩在剖宫产全麻中应用时对血流动力学、通气效果、血气分析、胃胀程度的影响。方法择期全麻下行剖宫产术患者40例,年龄18~40岁,体重62~86 kg ASAⅠ~Ⅱ级,麻醉诱导后置入喉罩评定疗效。结果喉罩置入后的MAP、HR与基础值比较均差异无统计学意义(P>0.05),VT、MV Peak、PETCO2及血气分析结果麻醉前后均在正常范围,胃胀程度评分0~2分占84.5%以上,没有大于5分的病例均不影响手术操作。结论剖宫产全麻应用喉罩控制气道对血流动力学影响小,可维持正常通气,不增加胃胀程度,术后并发症少。
Objective To observe the effects of inflatable laryngeal mask on hemodynamics, ventilation effect, blood gas analysis and bloating degree during cesarean section general anesthesia. Methods Forty patients (aged 18-40 years) with ASA Ⅰ ~ Ⅱ weighing 62-86 kg who underwent caesarean section undergoing elective general anesthesia were included in the study. Results There was no significant difference in MAP and HR between the laryngeal mask and the baseline (P> 0.05). The VT, MV Peak, PETCO2 and blood gas analysis results were in the normal range before and after anesthesia. The scores of bloating ranged from 0 to 2 Share more than 84.5%, no more than 5 cases did not affect the operation of surgery. Conclusion The application of laryngeal mask to control airway in cesarean general anesthesia has little effect on hemodynamics, can maintain normal ventilation, does not increase the degree of bloating, postoperative complications less.
