A 9-month-old infant presents with sudden-onset colicky pain, drawing up of knees, and passage of 'redcurrant jelly' stools. Ultrasound shows a target sign in the right upper quadrant. After successful pneumatic air enema reduction, the child should be observed for at least:
- A 2 hours and discharged if tolerating feeds
- B 6 hours and admitted overnight for monitoring
- C 24 hours as recurrence rate is highest in the first 24 hours post-reduction ✓
- D 48 hours with nil by mouth
Correct answer: C. 24 hours as recurrence rate is highest in the first 24 hours post-reduction
Explanation
After successful non-operative reduction of intussusception (pneumatic or hydrostatic enema), the recurrence rate is approximately 10%, with the majority of recurrences occurring within the first 24 hours. Observation for at least 24 hours is recommended; the child is kept in hospital, restarted on feeds, and monitored for signs of recurrence (return of pain, bloody stools) or perforation. Discharge after 2 hours risks missing early recurrence.
