[Acute intestinal intussusception: ultrasonic diagnosis and air insufflation].

Sixty-five children with intussusception were diagnosed by ultrasonography. Colonic air insufflation was the principle form of treatment. The diagnosis value of ultrasound was 100% and the success rate of reduction by air insufflation was 93%, after intrarectal injection of midazolam (0.3 mg/kg). The device for insufflation was simple, original and manual, with permanent control of intrarectal pressure. No complications were observed.
