目的观察咽喉表面麻醉慢诱导气管内插管对老年患者的影响.方法66例择期行上腹部手术患者，随机分为咽喉表面麻醉慢诱导气管内插管组(观察组)和快速诱导插管组(对照组)，每组各33例，观察两组诱导前(T0)及诱导后(T1)、插管即刻(T2)、插管后5 min(T3)的平均动脉压和心率、镇痛效果和不良反应.结果与T0比较，观察组诱导开始后各时点MAP、HR处于平稳状态，无显著性差异；与T0比较，对照组T1时MAP 明显下降(P <0.05)；T2、T3时MAP、HR皆明显上升并持续(P <0.05)；与观察组比较，对照组T2、T3的MAP、HR均显著增高(P <0.05)；观察组在插管期间1例出现心动过缓，对照组3例出现室性早搏；观察组病人可较好地耐受气管导管.结论咽喉表面麻醉慢诱导气管内插管对老年人更安全.%Objective To observe the surface anesthetic throat slow induction endotracheal intubation effects in elderly patients. Methods 66 cases of option forward line in patients with abdominal surgery were randomly divided into throat surface anesthesia slow induction endotracheal intubation group(observation group)and rapid induction intubation group(control group),each group of 33 cases,the changes of mean arterial pressure,heart rate,analgesic effect,adverse effect and before(T0)and after inducing (T1),Intubation immediate(T2),5 mins after windpipe intubation after windpipe intubation(T3)were observed. Results Comparison with T0,the MAP and HR of observation group were plateau after the start of induction each time,there was no significant difference;comparison with T0,the MAP of control group declined obviously at T1(P <0.05),MAP and HR of control group were significantly higher at T2、T3(P <0.05);comparison with observation group,the MAP and HR of control group were significantly higher at T2、T3(P <0.05);there was1 case with bradycardia of observation group during intubation;there was 3 cases ventricular premature beat of control group;the patient of the observation group can better withstand the endotracheal tube. Conclusion Throat surface anesthesia slow induction endotracheal tube for the elderly are more safety.
