Malignant Hyperthermia in Pediatric Surgery: Essential Awareness and Crisis Management

jpedsurg.org

Malignant hyperthermia (MH) is an unusual complication of surgery, and pediatric surgeons might not routinely account for the possibility of MH intraoperatively. Our team recently encountered an intraoperative MH crisis in an otherwise healthy child undergoing an elective laparoscopic procedure, and it served as a reminder of the need for awareness, early identification, and rapid intervention by both surgical and anesthesia teams. Here we present a summary of lessons learned from the encounter, and our perspective on what a pediatric surgeon should know about MH.

In brief

This article reviews a rare intraoperative malignant hyperthermia crisis during elective pediatric laparoscopy, emphasizing the importance of early recognition and coordinated team response. Pediatric surgeons gain practical insights on MH awareness, clinical signs, and rapid intervention protocols to improve patient safety during anesthesia.

MH can occur in healthy children during routine elective procedures; maintain high index of suspicion even in low-risk cases.
Early recognition and immediate dantrolene administration are critical; delays worsen outcomes in MH crisis.
Pediatric surgeons must collaborate closely with anesthesia teams to recognize MH signs: hyperthermia, rigidity, hypercarbia.
All surgical teams should know MH crisis protocols and dantrolene location, even if MH is rare in their practice.
Post-crisis monitoring is essential; MH can recur up to 24-48 hours after initial event requiring ICU-level care.
