【 摘 要 】

Objective: Cough at extubation and postoperative sore throat are common complications in patients receiving generalanesthesia with tracheal intubation. Different strategies have been used to reduce these effects. In this double blindcontrolled trial, we evaluated the effects of lidocaine sprayed onto the larynx and injected into tracheal tube cuff todecrease the incidence of cough at extubation and postoperative sore throat in patients undergoing total abdominalhysterectomy (TAH) under general anesthesia.Methodology: One hundred women, aged 40-60 years, scheduled for TAH under general anesthesia were included inthis randomized double blind prospective study. After induction of general anesthesia, just before tracheal intubation,glottus was sprayed by 4 % lidocaine or 0.9% saline through a syringe with 4 ml volume. After tracheal intubation, thetracheal tube cuff was filled with 4 ml of 2% lidocaine solution or 0.9% saline. In this way four groups were formed;spray-cuff group ( lidocaine spray and lidocaine in cuff), spray-saline group (lidocaine spray and saline in cuff) , salinecuffgroup (saline spray and lidocaine in cuff) , and saline-saline group (saline spray and saline in cuff) , having 25patients in each groups. The primary outcome was the incidence of cough at extubation. The incidence and severity ofsore throat was recorded at 15 min, 60 min and 24 hrs post-extubation using visual analogue scale (VAS, 0=no pain, 10=worst pain imaginable) as a secondary outcome.Results: All patients completed the study. Cough was noted in 20%, 16%, 76%, and 84% of patients in the spray-cuffgroup, spray-saline group, saline-cuff group and saline-saline group respectively. The spray of lidocaine onto the larynxresulted in decreased incidence of cough at extubation (P value < 0.001). But the intracuff lidocaine did not show anydecrease in the occurrence of cough or reduction in the incidence and severity of sore throat as it remained low in allgroups.
