What is the total duration of anesthesia time for a patient whose surgery starts at 08:00 am and ends at 09:30 am, with preparation starting at 07:30 am and release to PACU at 09:45 am?

To determine the total duration of anesthesia time, it is essential to account for the entire process, from the start of preparation through to the time the patient is released to the Post Anesthesia Care Unit (PACU).

The preparation begins at 07:30 am, indicating that the patient is being prepared for anesthesia. The surgical procedure starts at 08:00 am and concludes at 09:30 am. After the surgery ends, the patient remains in the anesthesia care until they are released to the PACU at 09:45 am.

1. Preparation Time: From 07:30 am to 08:00 am is 30 minutes of preparation.

2. Surgical Time: From 08:00 am to 09:30 am is 90 minutes of surgery.

3. Recovery Time: From 09:30 am to 09:45 am is an additional 15 minutes where the patient is still under anesthesia care.

When you sum these components, you get the total duration of anesthesia:

• 30 minutes (preparation) + 90 minutes (surgery) + 15 minutes (recovery) = 135 minutes.

However, if we review standard practices, anesthesia time often
