What does a nurse expect if a T-tube is functioning properly?

When a T-tube is functioning properly, observing drainage is crucial, and it can vary based on the patient’s condition and the specific reason for the T-tube placement. A greenish drainage is typically expected due to bile being collected from the common bile duct, especially after gallbladder surgery or other biliary procedures. This greenish color indicates that the bile is being adequately drained, suggesting the T-tube is functioning correctly in allowing bile to exit the body rather than being trapped.

Clear and yellow drainage may indicate a low volume of bile or potentially issues with the biliary system, while input exceeding output could suggest complications or blockages. The absence of drainage would typically raise concerns that the T-tube might not be patent or functioning as intended. Thus, consistent greenish drainage supports proper functioning of the T-tube.
