The incidence of postoperative sore throat was evaluated prospectively in 203 orotracheally intubated patients undergoing general anesthesia for surgical procedures. Patients were randomly assigned to have either a plastic oropharyngeal airway or a gauze bite-block in place during the operation and were evaluated for the occurrence of postoperative sore throat by questionnaire the day after surgery. The incidence of postoperative sore throat was 35.2% in the oropharyngeal airway group and 42.5% in the gauze bite-block group, not a statistically significant difference (P greater than 0.05). The incidence of postoperative sore throat was significantly higher when blood was noted on the airway instruments (64.5%) than when it was not (30.9%) (P less than 0.01). There was an association, although not statistically significant, between the incidence of postoperative sore throat and intubation by an anesthesia resident with less than 1 yr experience (P = 0.064). The data from this study indicate that the intraoperative use of hard plastic oropharyngeal airways, compared with the use of soft gauze bite-blocks, does not increase the incidence of postoperative sore throat. These data also suggest that pharyngeal trauma may contribute significantly to the development of postoperative sore throat. We suggest that aggressive oropharyngeal suctioning may contribute to this pharyngeal trauma.
对203例接受外科手术全身麻醉的经口气管插管患者的术后咽痛发生率进行了前瞻性评估。患者在手术期间被随机分配使用塑料口咽通气道或纱布咬口垫，并在术后第二天通过问卷调查评估术后咽痛的发生情况。口咽通气道组术后咽痛发生率为35.2%，纱布咬口垫组为42.5%，差异无统计学意义（P>0.05）。气道器械上有血迹时术后咽痛发生率（64.5%）显著高于无血迹时（30.9%）（P<0.01）。术后咽痛发生率与由经验不足1年的麻醉住院医师进行插管之间存在关联，尽管无统计学意义（P = 0.064）。本研究数据表明，与使用柔软的纱布咬口垫相比，术中使用硬塑料口咽通气道不会增加术后咽痛的发生率。这些数据还表明，咽部创伤可能是术后咽痛发生的重要原因。我们认为积极的口咽吸引可能导致这种咽部创伤。
