AbstractThe incidence and duration of hoarseness following tracheal intubation with general anesthesia were studied retrospectively from November 1998 to October 2000 in postanesthetic clinic of Nara Medical University. Total number of patients was 3977 and 37.1% of them complained of hoarseness. Most of there patients recovered within three days after surgery but in 4.2% the hoarshness persisted over ten days and in 0.7% persisted over one month after surgery. Most of these persistent hoarseness were considered to have originated from surgical procedures (such cervical, pulmonary, cardioaortic operation, etc.) and those following only tracheal intubation recovered within two months after surgery. The hoarseness decreased the satisfactory level for anesthesia in 1.0% of total patients and 12.8% of patients with persistent hoarseness. We consider that preoperative explanation and postoperative communication by anesthesiologists are important.
