N2 - Preoxygenation is a simple technique to expand the time under planned apnea till the patient is endangered by hypoxia. In this study, we analysed how preoxygenation is used by anaesthesiologists in clinical routine and how this method is tolerated by the patients. One hundred and twenty-one anaesthesiologists of 4 hospitals were interviewed anonymously about training level, rank, indication for preoxygenation and techniques of preoxygenation, as well as their estimation of the patients' discomfort during preoxygenation. Data on 100 patients about oxygen-mask-tolerance were acquired by an anonymous questionnaire from a standard quality control inquiry. We received back 76 of the 121 questionnaires of anaesthesiologists (63 %). Fifty-nine percent of the anaesthesiologists (45/76) preoxygenated in clinical routine. With increasing training time and higher ranks, less anaesthesiologists preoxygenated routinely: junior residents: 80 %; senior residents: 68 %; consultants: 60 %; assistant medical directors: 48 %.80 % of the anaesthesiologists (61/76) used imperfect techniques for preoxygenation (e. g. oxygen-flow <8 l/min). At the time of preoperative evaluation, the patients estimated the discomfort during preoxygenation on a continuous scale (1 to 10) as 2 (median; 1 - 7: 95 % confidence interval). Postoperatively, the patients mentioned no discomfort: 1 (1 - 1). The anaesthesiologists overestimated their patients' discomfort significantly with 5 (3 - 7) (p <0.001).In conclusion, preoxygenation, a simple safety procedure, is not routinely used by many anaesthesiologists and imperfect methods are often employed. A possible reason for the anaesthesiologists' reluctance to preoxygenate is an overestimation of the patients' discomfort, though the patients tolerate preoxygenation very well
