[Creatininphosphokinase isoenzymes in anaesthesia-induced myoglobinuria (AIM) (author's transl)]
Insights
Postoperative myoglobinuria can occur in pediatric patients after general anesthesia and succinylcholine administration, even without hyperthermia. This reaction to succinylcholine, a muscle relaxant, is more common than previously thought and warrants attention.
Area of Science:
- Anesthesiology
- Pediatric Medicine
- Clinical Pharmacology
Context:
- Pediatric patients aged 4-16 years undergoing surgery.
- General anesthesia with succinylcholine for intubation.
- Commonly for tonsillectomies and/or adenoidectomies.
Purpose:
- To screen pediatric patients for anesthesia-induced myoglobinuria post-operatively.
- To determine the incidence of myoglobinuria after succinylcholine administration.
- To investigate potential causes and implications of this adverse reaction.
Summary:
- A three-year study screened 1704 pediatric patients for myoglobinuria post-anesthesia.
- Seven cases (0.4%) of postoperative myoglobinuria without hyperthermia were identified.
- This indicates anesthesia-induced myoglobinuria is more frequent than previously reported.
Impact:
- Highlights a potential risk associated with succinylcholine in pediatric anesthesia.
- Suggests that anesthesia-induced myoglobinuria is not always benign.
- Underscores the need to consider genetic factors in creatine phosphokinase (CPK) levels and isoenzymes.
Abstract:
During a three year period, pediatric patients 4 to 16 years old were post-operatively screened for anaesthesia-induced myoglobinuria. All investigated cases had general anaesthesia and received succinylcholine prior to intubation. Anaesthetics were predominantly performed for tonsillectomies and/or adenoidectomies. Of a total of 1704 anaesthetics, 7 (0.4%) resulted in postoperative myoglobinuria without hyperthermia. Anaesthesia-induced myoglobinuria occurs more often than previously presented. This abnormal reaction to succinylcholine is not harmless in all cases. The possible genetic influence on total CPK and its isoenzymes is discussed.
