From a study on 160 patients it is concluded that tracheal incubation during general anesthesia increases the incidence and severity of sore throat complaints postoperatively. However, lubricating the tube does not influence the incidence or severity of these complaints. Therefore, if prevention of sore throat and hoarseness postoperatively is the sole consideration for tracheal tube lubrication, the addition of a lubricant seems unnecessary. However, lubrication of the tracheal tube may be used as a vehicle for drug administration, e.g., lidocaine. Or, it may be used to facilitate passage of the tube through the oropharynx, in which case, the least expensive lubricant may be chosen.
