Dude even if you left while she was in surgery, the nurses will call you once she is out to let you know to come back before she is awake. You also wake up around 20 min - 1 hour after surgery normally (unless the surgery was like 3+ hours then you’ll likely sleep longer)
The point of someone else being there during the surgery is to be there when you wake up and also to take you home (because the nurses will notify people that your surgery went well or poorly if you request that). Seeing as he only brought a motorcycle he clearly wasn’t taking her home so he failed at the one thing he went there for
But instead of waking up and having someone there to help her, to keep her company and regulate after the surgery, or to help her by getting her water or tissues or calling a nurse in, she had to be alone in bright white sterile rooms while coming out of all of the medications and only had nurses stopping in every once in a while to take care of her.
