双腔气管导管热软化预处理对术后咽喉痛、声音嘶哑的影响

The Effects of Thermal Softening of Double-Lumen Endobronchial Tubes on Postoperative Sore Throat and Hoarseness

为了观察经过热软化预处理的双腔气管导管(double-lumen endotracheal tube,DLT)对术后咽喉痛、声音嘶哑的影响。本研究选择择期行胸腔镜下肺叶切除术患者140例,随机分成热软化组(thermal softening,TS)和未热软化组(no thermal softening,NTS),每组70例。将热软化组DLT置于(40±1)℃温盐水中浸泡,对照组DLT置于室温(24±1)℃盐水中浸泡,两组均浸泡10 min;在拔管后24 h、48 h和72 h对患者咽喉痛和声音嘶哑发生率和严重程度进行评估的方法。通过以上方法得出患者术后咽喉痛发生率热软化组16/70,非热软化组28/70,热软化组明显低于非热软化组(p<0.05)。患者术后声嘶发生率热软化组17/70,非热软化组20/70,两组之间的嘶哑的发生率无明显差异。表明经过热软化的DLT行气管插管与未加热软化比较可明显降低术后咽喉痛的发生率,有助于减少与DLT插管相关的气道损伤。

To observe the effect of double-lumen endotracheal tube （DLT） on postoperative sore throat and hoarseness after heat-softening pretreatment. In this study, 140 patients underwent thoracoscopic lobectomy were randomly divided into heat softening group and no heat softening group. The control group DLT was immersed in water at room temperature （24±1）℃, and the two groups were soaked for 10 minutes. After 24 h, 48 h and 72 h after extubation, H Methods for assessing the incidence and severity of sore throat and hoarseness in patients. The incidence of sore throat was 1 6/70 in the softening group and 28/70 in the non-heat softening group, which was significantly lower than that in the non-heat softening group （p 〈0.05）. The incidence of hoarseness in the patients was 17/70 in the softening group and 20/70 in the non-heat softening group. There was no significant difference in the incidence of hoarseness between the two groups. Indicating that the heat-cured DLT tracheal intubation compared with the non-heating softening can significantly reduce the incidence of postoperative sore throat, help to reduce the DLT intubation associated with airway injury.
