Also to prevent ileus[edit]

Another reason to fast before surgery is to prevent ileus---is that correct? Sorry, I don't have time to add that information to the article. —Preceding unsigned comment added by 63.125.124.226 (talk) 16:11, 28 August 2008 (UTC)[reply]

Ileus is more of a complication of gastrointestinal surgery, but to my knowledge it isn't prevented by fasting. —Cyclonenim (talk · contribs · email) 16:24, 28 August 2008 (UTC)[reply]

Gastric conditions[edit]

Administering an antacid will reduce the acidity. This will increase the pH, not lower it. —Preceding unsigned comment added by 47.128.181.254 (talk) 17:41, 28 August 2008 (UTC)[reply]

Thanks, I've sorted it. —Cyclonenim (talk · contribs · email) 19:42, 28 August 2008 (UTC)[reply]

Why?[edit]

Why it is that I can't drink water before getting a general anesthetic? McAusten (talk) 01:39, 13 August 2011 (UTC)[reply]

Irrelevant photo of surgery[edit]

Showing coronary surgery is irrelevant. Yes, we know what surgery is. If you want to see pictures, go to article. Pictures here should maybe show general vs local anesthetic, or diagram how/why the body reacts to it. I'm removing the photo, since on top of being irrelevant and silly, it's kinda icky.

Is fasting really necessary or useful before sedation?[edit]

A really interesting editorial on this issue can be found here: [1] and a review (for which I don't have access to) here: [2]. --Signimu (talk) 02:20, 6 October 2019 (UTC)[reply]

"Latest guidelines" citation does not support claim[edit]

I was surprised to see the claim in the article, repeated twice, that "The latest guidelines do not support preoperative fasting", which doesn't match my understanding at all, or the rest of the article. I followed the citation, and indeed, it does not support the claim. The citation is to an article specifically about bariatric (weight loss) surgery, and the following half of the sentence, "there is no difference in residual gastric fluid volume, pH or gastric emptying rate following semi-solid meals or drinks, whether in obese or lean individuals" is taken out of context -- in the source, it is comparing BETWEEN obese and lean individuals undergoing surgery, but in the article it is put in a context where it appears to claim there's no difference between fasting and not. The source clearly states: "Presently, anaesthesia societies recommend intake of clear fluids up to 2 h and solids 6 h before induction of anaesthesia in healthy [75, 76] and obese [76] patients." which matches the rest of the article. The source does note that "No differences were found in RGFV and pH in a randomised study of morbidly obese patients who drank 300 ml of clear fluid 2 h before induction of anaesthesia, compared with those who fasted from midnight [71, 72]." which matches the two-hour recommendation for clear fluids.
