How many hours a day does an anesthesiologist work?

An anesthesiologist may work 10-12 hours a day on average, including time spent in actual cases, preoperative patient evaluation, post-operative patient visits, research, and administrative tasks. However, the actual number of hours worked can vary depending on factors like the specific practice setting, the hospital or clinic's patient load, the anesthesiologist's experience and caseload, and the surgeon's preferences.
