Assessing effects of intubating stylet use on early postoperative pharyngeal pain

In a small size randomized clinical trial assessing the effects of stylet use during tracheal intubation on early postoperative pharyngeal pain in anesthetized patients, Komasawa et al. [1] show that stylet use results in an increased incidence of early postoperative pharyngeal pain. To differentiate the effects of one factor on primary study endpoint, however, all of other factors have to be standardized for avoidance of potential biases. In this study, postoperative pharyngeal pain was evaluated when patients leaved operation room after sufficient recovery.
