A rectal tube should not remain in place for more than 30 minutes at a time to minimize the risk of complications such as mucosal damage, pressure ulcers, perforation, or infection. For patients requiring frequent gas relief, the tube can be reinserted every 2-3 hours as needed, but continuous use beyond short periods is not recommended. When using a rectal tube, ensure it is properly lubricated with a water-soluble lubricant before insertion, secure it appropriately to prevent migration, and monitor the patient for any signs of rectal irritation, bleeding, or discomfort. Extended use of rectal tubes can lead to serious complications, as highlighted in a case report of a patient who developed a large rectal ulcer caused by the Flexi-Seal device 1. In healthcare settings, some protocols may allow for longer placement (up to several hours) in specific clinical situations with close monitoring, but this should be determined by the healthcare provider based on individual patient needs and risks. The goal should always be to use the least invasive method for the shortest time necessary to relieve symptoms. It is also important to consider the patient's overall condition and prognosis, as discussed in a tutorial on adult enteral tube feeding 2, and to be aware of potential complications such as rectal bleeding after insertion of a percutaneous endoscopic gastrostomy tube 3.
