BackgroundThe aims of this national survey were to determine the views of Korean people regarding the specialty of anesthesiology and the role of anesthesiologists and to consider the ways in which individual anesthesiologists and the Korean Society of Anesthesiologists inform the public.MethodsThis off-line national survey was conducted by a professional research organization to obtain exact and reliable data. The questionnaire included structured questions to identify perceptions of the specialty of anesthesiology and the role of anesthesiologists inside and outside the operating room, people's desire for explanation of anesthesia by anesthesiologists, and their opinion about the best way to raise awareness about anesthesia and anesthesiologists.ResultsOf the respondents, 25.2% did not know that anesthesiologists are in charge of anesthesia during surgery. Furthermore, even respondents who knew that had very little knowledge of anesthesiologists' actual roles inside and outside the operating room. Respondents wanted their anesthesiologist to inform them about their anesthesia.ConclusionsThe public's awareness regarding the role of anesthesiologists seems to be inadequate. To improve this awareness, in hospitals, each anesthesiologist should provide patients with more exact and detailed information. Simultaneously, the National Society of Anesthesiology should provide systematic information reflecting the public's thoughts.

An airway-exchange catheter (AEC) can increase the safety of exchanges of endotracheal tubes (ETTs); however, the procedure is associated with potential risks. We describe a case of esophageal misplacement of a single-lumen ETT after switching from a double-lumen tube, despite the use of an AEC as a guidewire. To avoid this, physicians should consider the insertion depth and maintenance depth of the AEC and should verify its position before changing ETTs and should perform, if possible, with simultaneous visualization of the glottis with direct or video laryngoscopy during the exchange. Additionally, the new ETT position should be confirmed by auscultation, end-tidal carbon dioxide, and portable chest X-ray.
