摘要
目的观察脑电双频指数(BIS)监测血管介入手术后喉罩替换气管导管的应用效果。方法40例择期全身麻醉(全麻)下行血管介入手术的患者,随机分为L组和T组,各20例。两组患者术中均气管插管,BIS监测麻醉深度维持在40~60,手术结束后,L组喉罩替换气管导管通气,T组维持气管插管通气。比较两组患者不同时刻[麻醉诱导前(T0)、喉罩替换气管导管时(T1)、复苏拔管或拔除喉罩后即刻(T2)、拔管或拔除喉罩后5 min(T3)]平均动脉压(MAP)、心率(HR)水平。结果T组T2、T3时的MAP分别为(89.55±3.67)、(86.60±1.78)mm Hg(1 mm Hg=0.133 kPa),均显著高于本组T1时的(79.10±3.90)mm Hg,差异具有统计学意义(P<0.05);T组T2、T3时的MAP水平均显著高于L组的(80.75±2.61)、(81.35±2.13)mm Hg,差异具有统计学意义(P<0.05)。L组T2、T3时的HR分别为(76.70±4.15)、(84.00±2.31)次/min,均显著低于T组的(83.25±3.40)、(86.05±2.21)次/min,差异具有统计学意义(P<0.05)。结论血管介入手术后喉罩替换气管导管,苏醒期血流动力学更稳定,安全性良好。
Objective To observe the application effect of hispeetral index(BIS)monitoring in replacement of tracheal tube with laryngeal mask after vascular intervention.Methods A total of 40 patients with vascular interventional surgery under elective general anesthesia were randomly divided into L group and T group,with 20 cases in each group.Patients in both groups were intubated intraoperatively,and the depth of anesthesia was maintained at 40-60 by BIS monitoring.After surgery,the laryngeal mask was replaced with the tracheal intubation ventilation in the L group,and tracheal intubation ventilation was maintained in T group.Both groups were compared in terms of mean arterial pressure(MAP),heart rate(HR)at different time points[before induction of anesthesia(TO),when replacing tracheal tube with laryngeal mask(T1),immediately after resuscitation or removal of the laryngeal mask(T2),5 min after the extuhation or removal of the laryngeal mask(T3)].Results In T group,the MAP at T2 and T3 were(89.55±3.67)and(86.60±1.78)mm Hg(1 mm Hg=0.133 kPa)respectively,which were significantly higher than(79.10±3.90)mm Hg at T1 in this group,and the difference was statistically significant(P<0.05).The MAP levels at T2 and T3 in T group were significantly higher than(80.75±2.61)and(81.35±2.13)mm Hg in L group,and the difference was statistically significant(P<0.05).The HR at T2 and T3 in L group were(76.70±4.15)and(84.00±2.31)beats/min respectively,which were significantly lower than(83.25±3.40)and(86.05±2.21)beats/min in T group,and the difference was statistically significant(P<0.05).Conclusion The replacement of tracheal tube with laryngeal mask after vascular intervention has more stable hemodynamics and safety in recovery period.
