1Department of Outpatient Surgery, Alegent Health Bergan Mercy Medical Center, Omaha, NE, USA.
Summary
Malignant hyperthermia (MH) is a rare but life-threatening crisis. This review details MH triggers, symptoms, and emergency treatment protocols for perianesthesia teams to ensure prompt and effective patient care.
Area of Science:
- Anesthesiology
- Critical Care Medicine
- Perioperative Nursing
Background:
- Malignant hyperthermia (MH) is a rare, severe pharmacogenetic disorder of skeletal muscle.
- It can manifest as a life-threatening crisis during or after anesthesia.
- Prompt recognition and management are critical for patient survival.
Purpose of the Study:
- To provide perianesthesia nurses, perioperative nurses, and anesthesia providers with essential information on MH.
- To review agents that trigger MH, its signs, and symptoms.
- To outline recommended treatments, equipment, and protocols for MH emergencies.
Main Methods:
- Literature review of malignant hyperthermia.
- Synthesis of information on MH triggers, pathophysiology, and clinical presentation.
- Compilation of current recommendations for MH management and nursing interventions.
Main Results:
- Identified volatile anesthetics and succinylcholine as primary MH triggers.
- Detailed early and late signs including hyperthermia, tachycardia, and muscle rigidity.
- Highlighted dantrolene as the primary medication for MH treatment.
Conclusions:
- Effective management of MH requires comprehensive knowledge by the perianesthesia team.
- Readiness of specific medications, equipment, and emergency supplies is crucial.
- Adherence to established protocols ensures cohesive and effective treatment of MH crises.
