Not universally adopted; institutional practice varies
No strong evidence for specific dosing protocol
Observation versus admission after reduction
Early discharge evidence
Early discharge 4 to 6 hours post-reduction is safe and cost-effective
Reduces hospital length of stay from 23 to 9 hours
ED discharge has slightly higher 48-hour return rate (aOR 3.43)
Re-reduction success remains equally high (84 to 94%)
ICD-10 codes
K56.1 Intussusception
SNOMED CT 73742007 Intussusception of intestine
Surgical management principles
Laparoscopic approach preferred when operatively indicated
Shorter hospitalization and equivalent outcomes
Bowel resection for necrotic segments
Patient Discharge Instructions
copy discharge instructions
What happened to your child
Intussusception is a condition where part of the intestine folds into itself
It was successfully treated by a procedure called an enema reduction
Air or fluid was gently used to push the intestine back into the correct position
Home care instructions
Diet after discharge
Start with clear liquids and advance to regular diet as tolerated
Small frequent feeds for infants
Stop feeds and return to ER if vomiting returns
Activity
Normal activity as child tolerates
No restrictions unless surgical intervention was performed
Medications
No specific medications required after successful reduction in most cases
Give pain relief as needed for mild discomfort
Return to ER immediately if your child has
Return to ER warning signs
Recurrence of episodic abdominal pain, crying, or drawing up of legs
Vomiting especially if green or bile-colored
Bloody or currant jelly stools
Lethargy or decreased responsiveness
Fever greater than 38.5 degrees Celsius
Abdominal distension
Refusal to eat or drink
Child appears very unwell or you are concerned
Follow-up plan
Scheduled follow-up
Family doctor or pediatrician follow-up within 24 to 48 hours
Closer follow-up for infants younger than 1 year
Return for any concerns before scheduled appointment
Recurrence information for caregivers
Recurrence rate is approximately 5 to 17% after successful treatment
Most recurrences happen within 72 hours
Recurrence is usually treated successfully the same way
More than 4 recurrences requires specialist evaluation
