Abstract
This second time-study of the anaesthetist's intraoperative period was conducted at The Ohio State University Hospitals. The study involved a total of 30 anaesthetic procedures. The activities of the anaesthetists were videotaped and analysed independently by three reviewers. Unlike our previous study, the present study was performed at a time when automatic noninvasive arterial pressure monitors, automatic ventilators and patient breathing circuit disconnect alarms were in use. The greatest amount of intraoperative time of the anaesthetist (59.1%) was spent monitoring the patient directly (44.8%) or indirectly (14.3%) via patient monitors. This represented an increase from our previous study attributable to the increased use of technology in the operating room. The anaesthetist still spent about 10-12% of his/her time completing patient records.
