They just brought him in for emergency surgery

even tho they didn't see anything on the ultrasound except a huge portion of his abdomen is abnormal while the portion ahead of it is normal. Implying an obstruction. So they're going to do exploratory
i spent 10 mins talking to the surgeon about my concerns with anesthesia. His reaction was that there's always risks with anesthesia, but only 1 in something like 10,000. I pointed out that it's much higher with English Bulldogs. I'm not sure why I had to point that out. Hopefully he already knew that.
I told him the Baxter stops breathing when he's just laying there sleeping. Let alone on anesthesia…. He said somebody will be there with him during recovery. I said someone needs to sit with him literally The entire time, and make sure he doesn't stop breathing. I even offered to come in and sit with him myself.Normally I wouldn't be worried about something like this, but I'm really worried about his ability to deal with anesthesia.
The surgeon also said, when obstructions have been there for longer than even 24 hours, they can cause tissue damage. And that they might need to cut out a portion of his intestines and then reconnect them. If the tissue had been damaged from the obstruction for too long. I'm so thankful you guys made me go back in to get him checked. It continues to blow me away the doctors can be presented with a situation like this and just send the dog home. Without even having a hunch that something serious might be up. Why are you and I the ones that know this. But the trained doctors just send me home. I am not even trained, and I knew this wasn't as simple as "wait-and-see". You would think their medical training would have recommended different advice.
is there anything I need to make sure of regarding the anesthesia, the surgery, or anything you can think of? Based on stories you've heard, or experiences you've had? Anything that they might forget, that I need to make sure to doublecheck on? I know how situations like these go. It's always that one oversight that causes the problem. Appreciate any input.
I'm sitting outside the animal hospital tonight. I'm not going to even drive home. I'll wait here.
