Abstract:
BACKGROUND: Tracheal intubation for general anesthesia often leads to trauma of the airway mucosa, resulting in postoperative sore throat and hoarseness. Numerous studies have investigated the factors as contributing causes, but the influence of method of anesthesia induction and time for extubation of the endotracheal tube has not been systematically examined. The aim of this study was to establish the effects of the methods of anesthesia induction and timing of extubation on postoperative sore throat and hoarseness. METHODS: Eighty patients with ASA physical status 1 or 2 were randomly divided into four groups. Group 1 patients (n=20) recieved succinylcholine 1.0 mg/kg for intubation and early extubated ; group 2 patients (n=20) recieved succinylcholine 1.0 mg/kg for intubation and lately extubated ; group 3 patients (n=20) recieved pancuronium 0.1 mg/kg for intubation and early extubated ; group 4 patients (n=20) recieved pancuronium 0.1 mg/kg for intubation and lately extubated. All patients were interviewed 6, 24, 48, and 72 hrs after operation by an anesthesiologist in a double-blind manner. RESULTS: The incidence of sore throat at postoperative 6 and 24 hrs were decreased in group 3 compaired with group 1, 2, and 4 (p<0.05), respectively. The severity of sore throat at postoperative 6 hrs were decreased in group 3 compared with group 1, 2 and 4 (p<0.05), and that of postoperative 24 hrs were decreased in group 3 compared with group 1 and 2 (p<0.05), respectively. The severity of hoarseness at postoperative 6 hrs were decreased in group 3 compared with group 2 (p<0.05). CONCLUSIONS: We suggest that postoperative sore throat and hoarseness may be developed more when extubation was perfomed lately than early. Therefore, early extubation provide advantage in terms of reducing sore throat and hoarseness in limited cases of anesthesia.
