Effects of video-assisted preanesthetic patient education on preanesthetic interview time; A prospective, single-blinded, randomized controlled trial.

Watching the informational video about anesthesia before preanesthetic evaluation could reduce the interview time by an average of 24 seconds, with no difference in patients' or doctors' satisfaction or anxiety compared to patients who did not watch it. Video-assisted preanesthetic patient education indicates that the load on anesthesiologists can be reduced.
