Summary
A patient experienced prolonged paralysis after anesthesia due to atypical cholinesterase, impacting muscle relaxant duration. This case highlights the importance of neuromuscular monitoring in anesthesia recovery.
Area of Science:
- Anesthesiology
- Pharmacology
Background:
- Post-maxillary surgery anesthesia recovery.
- Patient exhibited unresponsiveness to stimuli post-anesthesia discontinuation.
Observation:
- Absence of autonomic responses (sweating, lacrimation, mydriasis).
- Failure to elicit protective reflexes (coughing).
- Neuromuscular monitoring revealed residual paralysis from mivacurium.
Findings:
- Atypical cholinesterase identified as the cause of prolonged mivacurium action.
- Patient required mechanical ventilation for 9 hours in ICU.
- Patient recalled the awareness period without psychological distress due to anesthesiologist's reassurance.
Implications:
- Underscores the significance of identifying atypical cholinesterase for safe anesthesia practice.
- Demonstrates the value of neuromuscular monitoring in detecting residual neuromuscular blockade.
- Highlights the psychological impact of intraoperative awareness and the role of anesthesiologist communication.
