软质激光气管插管引光器引导患儿气管插管术的效果

Efficacy of flexible laser endotracheal intubation lightwand device in guiding endotracheal intubation in pediatric patients

摘要:

目的 评价软质激光气管插管引光器引导患儿气管插管术的效果.方法 拟行经口气管插管全麻手术患儿90例,ASA分级Ⅰ或Ⅱ级,年龄4~8岁,性别不限.采用随机数字表法分为2组(n=45):软质激光气管插管引光器组(A组)和直接喉镜组(B组).麻醉诱导后,A组在软质激光气管插管引光器引导下行气管插管术,B组在直接喉镜引导下行气管插管术.记录气管插管期间高血压和心动过速的发生情况、气管插管时间和成功情况.记录术后24 h咽痛、声音嘶哑、失声及吞咽困难的发生情况.结果 与B组比较,A组总气管插管成功率差异无统计学意义(P>0.05),首次气管插管成功率升高,气管插管时间缩短,高血压、心动过速和咽痛的发生率降低(P<0.05).结论 与直接喉镜相比,软质激光气管插管引光器引导患儿气管插管术的效果更佳.

Objective To evaluate the efficacy of the flexible laser endotracheal intubation light-wand device in guiding tracheal intubation in pediatric patients. Methods Ninety pediatric patients of both sexes, aged 4-8 yr, of American Society of Anesthesiologists physical statusⅠor Ⅱ, scheduled for elec-tive surgery under general anesthesia requiring oral tracheal intubation, were divided into 2 groups ( n=45 each) using a random number table method: flexible laser endotracheal intubation lightwand device group ( group A) and direct laryngoscope group ( group B) . After induction of anesthesia, orotracheal intubation was carried out with a flexible laser endotracheal intubation lightwand device in group A or with a direct la-ryngoscope in group B. The development of hypertension and tachycardia during intubation, intubation time, and rate of successful intubation were recorded. The development of complications such as sore throat, hoarseness, aphonia and dysphagia was recorded at 24 h after surgery. Results Compared with group B, no significant change was found in the total rate of successful intubation ( P>0. 05) , the rate of successful intubation at first attempt was significantly increased, incubation time was shortened, and the in-cidence of hypertension and tachycardia during intubation and sore throat after surgery was decreased in group A ( P<0. 05) . Conclusion The flexible laser endotracheal intubation lightwand device produces bet-ter efficacy in guiding tracheal intubation when compared with direct laryngoscope in pediatric patients.
