目的比较双管喉管与双管喉罩用于全身麻醉患儿的通气效果。方法拟行全身麻醉的患儿40例,ASAⅠ～Ⅱ级,随机分为双管喉管组(L组)和双管喉罩组(P组),每组20例。采用咪唑达伦0.05 mg/kg、丙泊酚1～2 mg/kg、芬太尼2～4μg/kg和阿曲库胺0.5 mg/kg进行麻醉诱导,待肌松完全后插入适宜型号的双管喉管或双管喉罩。记录插入时间和一次插入成功率;术中持续监测的脉搏氧饱和度(SpO2)、心率(HR)、气道峰压(Ppeak)和呼气末二氧化碳分压(PETCO2),间隔3分钟测量并记录一次无创血压;记录手术时间、清醒时间、拔除时间和术后24 h内咽部不良反应的发生情况。结果两组插入时间和一次插入成功率比较差异均无统计学意义(P>0.05);两组血流动力学平稳,SpO2、Ppeak和PETCO2均在正常范围内,且差异均无统计学意义(P>0.05);两组手术时间、清醒时间、拔除时间和术后24 h内咽部不良反应发生率比较差异无统计学意义(P>0.05)。结论双管喉管可以安全而有效地用于全身麻醉患儿,且通气效果与双管喉罩相似。
Objective To compare the ventilation effects of double-pipe and double-tube laryngeal masks for general anesthesia in children. Methods Totally 40 children with ASA Ⅰ ~ Ⅱ were randomly divided into two groups: group B (L group) and group B (Group B), with 20 cases in each group. Induction of anesthesia was induced with imidazole darun 0.05 mg / kg, propofol 1 ~ 2 mg / kg, fentanyl 2 ~ 4 μg / kg and atracurium 0.5 mg / kg. Tube or double laryngeal mask. The time of insertion and the success rate of one insertion were recorded. The intraoperative continuous monitoring of SpO2, HR, Ppeak and PETCO2 were performed at intervals of 3 minutes Record a noninvasive blood pressure; record operation time, awake time, removal time and incidence of postoperative adverse pharyngeal reaction within 24 h. Results There was no significant difference between the two groups in the insertion time and the success rate of one insertion (P> 0.05). The hemodynamics of the two groups were stable, SpO2, Ppeak and PETCO2 were within the normal range, and the difference was not statistically significant P> 0.05). There was no significant difference in operative time, awake time, removal time and incidence of adverse reactions in pharynx between the two groups (P> 0.05). Conclusions Double pipe throat can be safely and effectively used in children with general anesthesia, and the ventilation effect is similar to double laryngeal mask.
