Evaluation of "no touch" extubation technique on airway-related complications during emergence from general anesthesia

ABSTRACT

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" awake technique. The changes in HR, SBP, and DBP during emergence extubation were significantly less in "no touch" 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 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
