Describe the effects general anesthesia can have on the GI tract and how this effects post-operative feeding recommendations

Answer 1

General anesthesia may result in a post-operative ileus (lack of motility), a general paralysis of the gastrointestinal tract. Resolution of the ileus generally occurs within 24–48 hours, depending on the type of procedure. Traditionally, the patient was prevented from eating or drinking until the ileus was resolved, and the production of gas or bowel movement was a sign of resolution of ileus. Because it is difficult to ascertain when GI function has returned, however, the determination of when to actually begin post-operative feeding has been debated. However, early feeding may become standard in post-operative protocols. Many patients who have entered surgery with nutritional deficits cannot withstand additional weight loss. Allowing a patient to be fed as soon after surgery as is possible and safe is recommended.
