Abstract

METHODS

This randomized study compares spontaneous versus controlled ventilation in 60 ASA I and II patients undergoing tonsillectomy as regards haemodynamic stability, recovery characteristics, intra- and immediate postoperative complications and surgical impressions.

RESULTS

The patients in the balanced anaesthesia (B) group showed less haemodynamic variability compared to baseline after tracheal intubation, mouth gag application and removal and incision. Two patients had dysrhythmias in the B group compared to six in the spontaneous breathing (S) group. Six patients in the S group had a rise in endtidal carbon dioxide concentration above 7.8 kPa (60 mmHg). Recovery scores were higher in the B group at 10 and 20 min into recovery. The surgical impression of bleeding and jaw relaxation was similar with both groups. The incidence of postoperative nausea and vomiting and agitation was higher in the S group but did not achieve statistical significance.

CONCLUSION

Use of balanced anaesthesia offered more haemodynamic stability and a rapid recovery.

摘要

方法

本随机研究比较了60例接受扁桃体切除术的美国麻醉医师协会（ASA）I级和II级患者采用自主通气与控制通气在血流动力学稳定性、恢复特征、术中和术后即刻并发症以及手术感受方面的差异。

结果

与气管插管、放置和移除开口器以及切开后相比，平衡麻醉（B）组患者的血流动力学变异性较小。B组有2例患者出现心律失常，而自主呼吸（S）组有6例。S组有6例患者的呼气末二氧化碳浓度升高至7.8 kPa（60 mmHg）以上。恢复10分钟和20分钟时，B组的恢复评分更高。两组的手术出血和下颌松弛感受相似。S组术后恶心、呕吐和躁动的发生率较高，但未达到统计学意义。
