Recent reports of the incidence of postoperative sore throat following anaesthesia with tracheal intubation have claimed that low volume high pressure cuffs are preferable to those with high volume and low pressure. In this study similar methods were used for evaluating postoperative sore throat. Randomly selected tracheal tubes were used in 56 patients undergoing elective abdominal surgery, followed by direct questioning about sore throat on the first postoperative day. The incidence of postoperative sore throat was 41 per cent with high volume low pressure cuffed tubes and 55 per cent with low volume high pressure cuffed tubes. This difference is not statistically significant, but the tendency of the results is contradictory to those published earlier. The incidence of postoperative sore throat varies greatly if direct or indirect questioning is used and also varies between studies using the same method of questioning. Therefore the validity of this method for evaluating the influence of cuff design must be questioned. Postoperative sore throat is a symptom caused by many factors, such as the intubation procedure and the use of stylets or lubricants. The incidence of postoperative sore throat does not necessarily reflect damage caused by the tracheal tube cuff.
近期有关气管插管麻醉后咽痛发生率的报告称，小容量高压气管导管套囊优于大容量低压气管导管套囊。本研究采用类似方法评估术后咽痛情况。随机选择气管导管用于56例择期腹部手术患者，术后第一天直接询问咽痛情况。大容量低压套囊气管导管术后咽痛发生率为41%，小容量高压套囊气管导管术后咽痛发生率为55%。这一差异无统计学意义，但结果趋势与早期发表的研究结果相反。如果采用直接或间接询问的方式，术后咽痛发生率差异很大，且在使用相同询问方法的研究之间也存在差异。因此，这种评估套囊设计影响的方法的有效性值得质疑。术后咽痛是由多种因素引起的症状，如插管操作以及使用管芯或润滑剂等。术后咽痛发生率不一定反映气管导管套囊造成的损伤。
