Insights
Sedative reduction (SR) using ketamine, midazolam, and atropine can improve success rates for pediatric intussusception, potentially reducing the need for surgery after initial hydrostatic reduction (HR) failures.
Area of Science:
- Pediatric Gastroenterology
- Interventional Radiology
- Pediatric Surgery
Background:
- Intussusception is a common pediatric emergency.
- Hydrostatic reduction (HR) is the primary non-surgical treatment, but repeated failures may necessitate surgery.
- Sedatives are typically avoided in pediatric interventional radiology.
Purpose of the Study:
- To evaluate the efficacy of sedative reduction (SR) during the third attempt of hydrostatic reduction for pediatric intussusception.
- To determine if SR can decrease the rate of surgical intervention in refractory cases.
Main Methods:
- SR was performed using intravenous ketamine, midazolam, and atropine.
- Patients with contraindications for HR underwent laparoscopic reduction (LR).
- Data collected over 3 years from 43 patients undergoing SR.
Main Results:
- Successful reduction was achieved in 65.1% (28/43) of patients undergoing SR.
- Of the 15 patients with failed SR, 14 proceeded to LR without intestinal resection.
- No significant risk factors for failed SR were identified.
Conclusions:
- Sedative reduction (SR) with ketamine, midazolam, and atropine is effective for pediatric intussusception, particularly on the second or third hydrostatic reduction (HR) attempt.
- SR may significantly reduce the overall rate of surgical intervention for intussusception in children.
Abstract:
Intussusception is common emergency condition in children. Pneumatic or hydrostatic reduction (HR) is considered the first-choice management strategy in cases lacking indications for surgical intervention. Generally, sedatives are not used in children undergoing interventional radiology procedures. Surgical management is associated with long hospitalization durations and high costs, unlike nonsurgical reduction. To avoid surgery, reduction procedures are repeated despite initial treatment failure. However, in cases involving repeated failures, children should be referred for surgery.To ensure good response to reduction, we planned HR under sedation during the third reduction attempt. Sedative reduction (SR) was performed with the administration of ketamine, midazolam, and atropine. All patients with contraindications against HR underwent laparoscopic reduction (LR) without HR.During 3 years, SR was performed in 43 patients, and in 28 (65.1%), the treatment was successful. Among the 15 patients in whom the procedure failed, 14 underwent LR without intestinal resection. There was no significant risk factor contributing to failed reduction under sedation.During the second or third HR attempt, successful reduction may be ensured with the SR procedure with intravenous ketamine, midazolam, and atropine; this procedure may further reduce surgery rates in pediatric intussusception.
