Malignant hyperthermia in a 3-month-old infant: a case report
Journal of the Medical Association of Georgia
|September 1, 1996
Summary
Malignant hyperthermia (MH), a rare muscle disorder, occurred in a 3-month-old infant during surgery. This case challenges the notion that MH does not affect infants under one year old.
Area of Science:
- Anesthesiology
- Pediatric Surgery
- Pharmacology
Background:
- Malignant hyperthermia (MH) is a rare, life-threatening disorder of skeletal muscle metabolism.
- It is typically triggered by volatile anesthetics and succinylcholine.
- MH is more common in children than adults, but previously not reported in infants under 1 year.
Observation:
- A 3-month-old infant underwent surgical repair of a right inguinal hernia.
- The infant developed a malignant hyperthermia crisis during the procedure.
- Extremely elevated creatine phosphokinase (CPK) levels were noted 13 hours postoperatively.
Findings:
- This case report details the first documented occurrence of malignant hyperthermia in an infant younger than 1 year.
- The patient exhibited a severe presentation of MH, indicated by significantly elevated CPK levels.
- The successful management of MH in this young patient is highlighted.
Implications:
- This case expands the known age range for malignant hyperthermia susceptibility.
- It underscores the importance of vigilance for MH in infants, regardless of age.
- Further research may be needed to understand MH triggers and management in neonates and infants.
