This is not unusual though.
Whether human or veterinary medicine, shifts can be ridiculously long and exhausting.
I’ve known many people to pull an “Alaskan fisherman” (i.e. you find a quiet part of the hospital to go crash for a 15 min nap. It helps tremendously… at least for the next hour or two…). As senior student on clinics, it wasn’t unusual to get 3 hours of “proper” sleep a night, then make up enough sleep to remain partly functional by grabbing quick naps if there was a cancellation, or during a lunch break, etc…
I’m betting this guy was so fried that he was going to take a 15-30min nap while the patient was prepped for surgery, and was so zonked that he slept through whatever alarms he had set.
