Bowel Preparation Agents for Surgery or GI Procedures Bowel cleansing is done prior to GI surgery to reduce the bacterial load and thereby decrease the risk of peritoneal contamination by fecal material and subsequent infection. Similar treatment with the laxative component may be performed prior to endoscopic colonoscopy in order to provide better visualization of the bowel surface. The oral component of these treatments is administered the day before surgery. Sometimes, enemas may also be given prior to colonoscopy. Polyethylene Glycol Electrolyte Solution Polyethylene glycol electrolyte solution (PEG ES) (GoLytely ®, CoLyte ®, NuLytely ®), 4 liters, can be administered orally prior to GI examination. It can be given via a nasogastric tube to patients who are unwilling or unable to drink the preparation. The patient is instructed to drink 240 mL every 10 min until 4 L are consumed or until the rectal effluent is clear. Tap water may be used to reconstitute the solution. The first bowel movement should occur in about 1 h. Side effects include nausea, abdominal cramps, fullness and bloating, Read more [...]
