Pneumatic reduction of intussusception using carbon dioxide

Abstract

Pneumatic reduction using air has recently become popular for the initial non-surgical managment of intussusception. Since carbon dioxide (CO₂) is rapidly absorbed from body surfaces, it should theoretically result in less cramping and distension following reduction. We reviewed our recent experience with the pneumatic reduction of intussusception using CO₂ in 26 children. In 22 of these the intussusception was reduced (85%). There was one perforation with CO₂; the patient did not suffer any postoperative complications. Five additional children who had been treated unsuccessfully with barium had intussusception subsequently reduced with CO₂. Following CO₂ reduction, most children were fed within hours, and there were no instances of significant abdominal distension or cramping. We conclude that pneumatic reduction of intussusception using CO₂ is safe and effective, and has the theoretical advantage of more rapid absorption from the gastrointestinal tract than air.
