Compared with deflating a tracheal tube cuff with a 10-ml syringe in 1 s, deflating continuously and slowly until the pressure reduce to zero via a cuff pressure gauge in 5 s or using a 10-ml syringe at a speed of 1 ml sIn this trial, we adopted a cuff pressure gauge for deflation to modulate the speed of deflation according to cuff pressure objectively. We designed a group to deflate with a 10 ml syringe at a speed of 1 ml sTracheal tube cuff is in closest contact with the tracheal mucosa, so most stimulation come from the cuff [Postoperative airway complications in this study were mainly sore throat and hoarseness. They were caused by inflammation and stimulation of the airway due to the pressure exerted on the tracheal wall by the endotracheal [Hans-Joachim P reported when the cuffs deflated, positive airway pressure cannot be maintained until the moment of extubation, and effective lung inflation prior to extubation cannot be performed. This hinders the generation of cough, and impair effective removal of secretions from glottic and subglottic areas during extubation. So, the report recommended to remove endotracheal tube while the lungs are inflated by positive pressure with endotracheal tube cuffs inflated, it generates an effective cough to expel secretions and blood from the glottic and subglottic areas during tracheal extubation [Should we decrease the incidence of cough reflex when extubation? Although cough is a protective mechanism, there are circumstances patients are vulnerable and susceptible to coughing. For example, cough may trigger an abrupt increase in intracranial, intracavity, or intraocular pressure, and these can lead to hypertension, tachycardia, arrhythmia, and cardiovascular collapse. Also, they may induce bronchospasm, laryngospasm, and other airway complications especially in asthma patients, children with upper respiratory tract infections (URIs). In these patients, prevention of cough reflex is warranted. However, before medication prevention for the suppression of cough reflex, the benefit and potential harm must be carefully weighed. For instance, patients undergoing cardiac surgery, with arrhythmia or interventional cardiac procedures should avoid lidocaine [This trial has some advantages. No study has investigated the effect of extubation using a cuff pressure gauge, and we designed a group that used a 10-ml syringe at 1 ml sIn conclusion, this study demonstrated that in patients with normal BMI undergoing operations within 3 h, deflating the tracheal tube cuff continuously and slowly until the pressure was zero in 5 s using a cuff pressure gauge or using a 10-ml syringe at 1 ml s
