INTRODUCTION: Sore throat and hoarseness often follow general anesthesia administered via a single-lumen endotracheal tube (SLT). Numerous studies have investigated the role of factors as contributing causes, but the influence of double-lumen endobronchial tube (DLT) has not been examined systemically. The goal of this study was to examine the incidence of sore throat and hoarseness after DLT insertion. METHODS: 70 patients who were intubated with SLT or DLT were studied. Sore throat and hoarseness were evaluated after 24~48 hr from extubation of each tubes. RESULTS: In SLT and DLT group, the incidence of sore throat and hoarseness was 14 patients (40%) vs 16 patients (45.7%) and 8 patients (22.8%) vs 10 patients (28.5%), respectively. CONCLUSIONS: There are no statistical differences in incidence of sore throat and hoarseness between SLT and DLT.
