全麻气管插管的教学观察

目的:观察气管插管教学中伴随的问题及术后喉痛及声音嘶哑的发生情况,以期提高气管插管教学的质量。方法:100例全麻手术患者随机分为教学组和医师组,每组50例。记录2组的插管时间、脱氧合发生率和尝试插管次数,并在患者离开麻醉后恢复室时和术后24 h评估患者喉痛和声音嘶哑情况。结果:插管时间、脱氧合发生率和插管次数在教学组均显著高于医师组(P<0.01)。医师组的喉痛视觉模拟评分显著低于教学组(P<0.01),而2组声音嘶哑发生率差异无统计学意义(P>0.05)。结论:气管插管教学会延长插管时间并增加插管次数,同时增加气道损伤的概率。

Observation of tracheal intubation teaching

Objective: To observe the problems in endotracheal intubation teaching and the incidence of postoperative sore throat and hoarseness so as to improve the teaching quality of intubation.Methods: One hundred patients undergoing general anesthesia were randomized into teaching group(n=50) and anesthetist group(n=50).The time length of intubation,incidence of deoxygenation and number of intubating attempts were recorded in both groups.The postoperative sore throat and hoarseness were also assessed when the patients departed from the Postanesthesia care unif and 24 hours after the operation.Results: The time length of intubation,incidence of deoxygenation and number of intubating attempts in the teaching group were significantly higher than those in the anesthetist group(P<0.01);the severity of sore throat was significantly less in the anesthetist group than that in the teaching group(P<0.01);however,there was no significant difference in the incidence of hoarseness between the two groups(P>0.05).Conclusions: Endotracheal intubation teaching will extend the time length of intubation,increase the number of intubating attempts and increase the risk of airway injuries.
