It depends where you are at. I worked at tampa general hospital and my calls were horrible. Start at 7am and leave the next day after you start you rooms and someone relieves you.
Average night- 5 to 6 traumas a night, usually ortho, but sometimes gunshots or stabbings. 10 add ons a night, almost always urgent chole's?? and the leftover's from the day shift. 5-6 code blues, 10 epidurals, 3-6 c-section's and the consults for central lines which is around 5-6 per night.
Private vs Residency- Again depends if you have a trauma center. I worked with residents at TGH but it still sucked ass. I am currently at a different program in Texas and calls are sweet. Start at 3pm and your off at 7 am no questions asked. No central lines consults, min if any trauma, a few cases left over from the day 2 to 3 and occasional stat intubations. Again, depends the hospital that you at. The current hospital I am at is much smaller than Tampa general and the catch area for patients is also smaller.
