Magnesium as an adjuvant for caudal analgesia in children

Area of Science:

• Pediatric Anesthesiology
• Pain Management
• Pharmacology

Background:

• Effective caudal block adjuvants are needed to prolong analgesia and improve functional recovery in pediatric patients.
• Magnesium acts as an N-methyl-D-aspartate receptor antagonist, offering analgesic properties.
• This study investigated magnesium's efficacy as an adjuvant for caudal block in children.

Purpose of the Study:

• To evaluate the effectiveness of magnesium as an adjuvant to caudal block for postoperative analgesia in children.
• To assess the impact of magnesium on functional recovery after surgery.
• To compare pain scores, analgesic consumption, and adverse effects between groups.

Main Methods:

• A prospective, randomized, double-blinded study involving 80 children (2-6 years) undergoing inguinal herniorrhaphy.
• Caudal block administered with ropivacaine alone (Group R) or ropivacaine with 50 mg magnesium (Group RM).
• Evaluation of Parents' Postoperative Pain Measure (PPPM) scores, analgesic use, functional recovery, and adverse events.

Main Results:

• Group RM showed significantly lower PPPM scores post-discharge compared to Group R.
• Children in Group RM required less fentanyl for rescue analgesia and fewer oral analgesics after discharge.
• Faster return to normal functional activity was observed in Group RM.

Conclusions:

• Magnesium (50 mg) as an adjuvant to caudal analgesia significantly enhances postoperative pain relief in children.
• This adjuvant therapy leads to a quicker return to normal functional activity compared to local anesthetic alone.
• Magnesium supplementation in caudal blocks offers a superior approach to pediatric postoperative pain management.
