Nasogastric Tube Clamping Trial vs. Immediate Removal

Once the NG tube output is less than 500 mL over a 24 hour period with at least two other signs of return of bowel function the NG tube will be removed. Other signs of bowel function include flatus, bowel movement, change of NG tube output from bilious to more clear/frothy character, and hunger.

Once the NG tube output is less than 500 mL over a 24 hour period with at least two other signs of return of bowel function, a 4 hour clamp trial will be performed. Other signs of bowel function include flatus, bowel movement, change of NG tube output from bilious to more clear/frothy character, and hunger. The NG tube will be taken off of suction and clamped. The NG tube is then reconnected to suction at the end of the four hour clamp trial and removed if less 125 mL drains or kept in place if greater than 125 mL drains. The same initial criteria are used again to determine if a clamp trial will be performed after 24 hours.
