Abstract

Malignant Hyperthermia (MH) is a rare but severe reaction to anesthesia-inducing agents, characterized by hyperthermia, muscle rigidity, and tachycardia. At the University of Louisville Hospital Outpatient Surgery Center (ULH OSC), an increase in MH cases prompted a quality improvement (QI) initiative aimed at improving perioperative staff's knowledge, confidence, and proficiency in managing MH events.

The project utilized a blended educational approach, incorporating hands-on simulation and online learning modules. Staff completed pre- and post-simulation self-assessments to measure changes in knowledge and confidence. The PDSA model guided process development, with simulations identifying barriers to effective MH management. Key barriers included the absence of an I-stat machine, lack of CO2 monitoring in the PACU, and deficiencies in the MH cart. Simulations revealed challenges such as delayed MH cart retrieval, failure to call the MHAUS hotline, and a lack of proficiency in mixing dantrolene, despite pre-simulation KNOW module completion.

Findings demonstrated an average knowledge increase of 0.15 across survey metrics, though gaps in confidence and team dynamics persisted. Simulations effectively highlighted systemic issues, allowing leadership to address equipment deficits and update the MH cart. The hands-on approach was instrumental in improving staff preparedness and identifying actionable improvements.

Future practice implications include regular simulation-based MH training to enhance readiness and address the limitations of rare-event scenarios. Continued efforts to refine training and equipment availability will be vital in optimizing patient care during MH emergencies.
