A rectal catheter is configured for improved pediatric care. The catheter includes a member that terminates into a rounded tip, a plug mounted about the member, the plug being made of a moldable material, a balloon mounted about the member between the rounded tip and the plug, a conduit that fluidly communicates with the balloon and that extends from the member to enable a pressure source to be operatively connected to the balloon to inflate the balloon, and a pressure relief valve operatively connected to the conduit, the pressure relief valve being configured to open the conduit to atmosphere pressure in response to a pressure in the conduit reaching a predetermined pressure. The predetermined pressure is selected to attenuate significantly risk of bowel perforation in pediatric patients.
