Core Tip
Core Tip: Hyponatremic encephalopathy caused by the use of polyethylene glycol (PEG) solution for intestinal cleaning is rare, which can lead to irreversible sequelae and even death. This case is a female with neurological dysfunction due to hyponatremia induced by the use of pegylated for bowel preparation before colonoscopy. The patient was in a coma with the brain suggesting cerebral edema, and was transferred to the intensive care unit for treatment with 3% sodium chloride injection. The patient's medical history should be fully understood before using PEG for bowel preparation, as both untimely and overtreatment can lead to serious complications.
