目的：观察并比较 Supreme 喉罩（Supreme laryngeal mask，SLMA）与可视喉镜插管在全身麻醉诱导期和恢复期对血流动力学的影响。方法：选取全身麻醉手术患者60例，随机分成两组：喉罩组（A 组）和可视喉镜组（B 组），每组各30例。每组麻醉的诱导和维持均采用相同公斤体重量的相同麻醉药。分别记录各组麻醉诱导期和恢复期不同时间点的平均动脉压（ MAP）、心率（HR）、血氧饱和度（SpO2）。术后24 h 随访并记录患者并发症发生情况。结果：喉罩组患者在置入前后、拔除前后的 MAP、HR 无明显变化。可视喉镜组患者插管、拔管前后的 MAP、拔管前后的 HR 出现明显波动，以 MAP 波动最为明显。组间比较，拔除后3 min 的 MAP、HR 可视喉镜组比喉罩组明显低。并发症发生率 A、B 组分别为30.0％、36.7％，其差异无统计学意义（ P ﹥0.05）。结论：SLMA 置入全身麻醉对麻醉诱导期和恢复期血流动力学的影响比可视喉镜插管全身麻醉更小，出现的并发症也较轻，值得在有适应症的患者上广泛使用。%Objective To compare of hemodynamic changes of the general anesthesia by SLMA insertion with which tracheal intubation by video laryngoscope during induction and recovery of anesthesia. Method Sixty patients with general anesthesia were randomly divided in-to two groups. Each group was anesthetized using the same anesthetic. The datas of MAP 、HR and SpO2 in different time during induction of anesthesia and recovery period were recorded. Patients were followed - up after 24 hours later. And all the adverse reactions were recor-ded. Results MAP and HR were no significant changes in group A before and after the placement or extraction. While there were significant changes in group B of them,there were the most obvious changes in MAP. The MAP and HR after the removal of visible 3 min in group B were significantly lower than in the one in group A. The complication rates was 30. 0% in group A,and 36. 7% in group B. The difference had no statistical significance(P ﹥ 0. 05). Conclusion The effects of SLMA on hemodynamics in general anesthesia during anesthesia in-duction and recovery period are smaller than of which video laryngoscope intubation. And SLMA is worth widely use.
