Awake "no touch" extubation requires performing extubations only when the patient spontaneously wakes up without any kind of stimulation during emergence from general anesthesia. The aim of this study was to evaluate absolutely awake extubation "no touch" technique in adult patients, scheduled for elective nasal and paranasal sinus surgeries under general anesthesia as regard to emergence airway complications.
A total of 60 adult patients were randomly allocated into one of two equal groups according to the method of extubation: Group I: Standard fully awake, Group II: Absolutely "no touch" awake extubation (absolutely no stimulation no touch was allowed until patients were able to open their eyes). The incidence of laryngospasm and its grade according to a four-point scale was reported. Occurrence of airway events (excessive secretions, breath-holding, coughing, hoarseness, biting, as well as the number and severity of any desaturation episodes), oozing from the wound, and postoperative sore throat were also recorded. The heart rate (HR), systolic (SBP) and diastolic (DBP) blood pressure measured at the end of surgery served as baseline values, and subsequent measurements were taken within 30 minutes after the end of surgery.
There was absolutely no case of laryngeal spasm or episode of desaturation among patients who were extubated with the "no touch" technique. On the other hand, there were 3 cases of laryngeal spasm in standard fully awake group. Severity of coughing, excessive secretions and breath holding, hoarseness, biting, and occurrence of non-purposeful movements of the limbs were significantly less in the absolutely "no touch" technique awake technique. The changes in HR, SBP, and DBP during emergence extubation were significantly less in "no touch" technique technique group. However, oozing from the wound was significantly higher with standard fully awake extubation. However, there were no significant differences between the two groups regarding the incidence of postoperative sore throat (39 and 36%, respectively).
The results of the present study showed that awake "no touch" technique technique for tracheal extubation produces less airway-related complications, as well as minimal hemodynamic response during emergence from general anesthesia in nasal and paranasal surgeries. It could be a safe alternative for tracheal extubation in airway surgery.
清醒“无接触”拔管要求仅在患者从全身麻醉苏醒过程中自发醒来且无任何刺激时进行拔管。本研究的目的是评估在全身麻醉下行择期鼻及鼻窦手术的成年患者中,绝对清醒拔管“无接触”技术在预防苏醒期气道并发症方面的效果。
根据拔管方法,将60例成年患者随机分为两组,每组人数相等:第一组:标准完全清醒拔管组;第二组:绝对“无接触”清醒拔管组(在患者能够睁眼之前,绝对不允许有任何刺激和接触)。报告喉痉挛的发生率及其根据四点量表划分的等级。记录气道事件(分泌物过多、屏气、咳嗽、声音嘶哑、咬管,以及任何血氧饱和度下降事件的数量和严重程度)、伤口渗血情况和术后咽痛情况。手术结束时测量的心率(HR)、收缩压(SBP)和舒张压(DBP)作为基线值,术后30分钟内进行后续测量。
采用“无接触”技术拔管的患者中绝对没有发生喉痉挛或血氧饱和度下降的情况。另一方面,标准完全清醒组有3例喉痉挛。在绝对“无接触”技术清醒拔管组中,咳嗽、分泌物过多、屏气、声音嘶哑、咬管以及肢体无目的运动的严重程度明显较轻。“无接触”技术组在拔管苏醒期HR、SBP和DBP的变化明显较小。然而,标准完全清醒拔管组的伤口渗血明显更多。不过,两组在术后咽痛发生率方面没有显著差异(分别为39%和36%)。
本研究结果表明,在鼻及鼻窦手术中,清醒“无接触”气管拔管技术在全身麻醉苏醒期产生的气道相关并发症较少,血流动力学反应也最小。它可能是气道手术中气管拔管的一种安全替代方法。
