In peritoneal dialysis, what is the reason for keeping the drainage bag below the abdomen?

• A. To prevent infection
• B. To allow gravity-driven drainage and prevent backflow
• C. To prevent tubing kinks
• D. To speed up drainage by raising the bag

Answer: (B)

In peritoneal dialysis, drainage relies on gravity. Placing the drainage bag below the abdomen creates a hydrostatic pressure gradient that pulls the spent dialysate out of the peritoneal cavity and into the bag. This setup also helps prevent backflow into the abdomen, reducing the risk of contamination and incomplete drainage. If the bag were level with or above the abdomen, drainage could be slow or reverse into the cavity, making the process less efficient and increasing contamination risk.
