A 7-kg 8-month-old boy was transferred to our institution after failed enema reduction of intussusception elsewhere. During the redo intervention using a 6-fold-diluted solution of Gastrografin with water as contrast medium, the bowel was perforated. Urgent surgical repair was planned and preoperative examination revealed serum sodium of 137 mEq x l(-1). On arrival in the operating room, the patient presented abdominal distension, drowsiness and tachypnea. His trachea was intubated and anesthesia was maintained with sevoflurane. Arterial blood examination immediately before the surgery (approximate by 80 minutes after the previous blood test) showed the following findings: pH 7.27, base excess -8.5 mEq x l(-1) and sodium 122 mEq x l(-1). Watery ascites estimated at 450 ml was evacuated upon a peritoneal incision. At termination of anesthesia, serum sodium recovered to 133 mEq x l(-1), resulting from replenishment of electrolytes and sodium bicarbonate administration. The patient became fully awake and his trachea was extubated in the operating room. Gastrografin has osmolarity of 1,900 mOsm x l(-1), containing sodium of 158 mEq x l(-1). Massive intraperitoneal accumulation of diluted Gastrografin is a rational explanation for the rapidly developed hyponatremia, which can lead to hyponatremic encephalopathy, especially in infants. Prompt surgical intervention is therefore essential for successful management of such cases.
