Pseudocholinesterase Deficiency: What the Proceduralist Needs to Know

Area of Science:

• Anesthesiology
• Clinical Genetics
• Pharmacology

Background:

• Pseudocholinesterase deficiency is a rare disorder affecting choline ester metabolism.
• It can be inherited or acquired, impacting individuals with an autosomal recessive trait.
• The condition is often asymptomatic until exposure to specific anesthetic agents.

Observation:

• A patient experienced prolonged paralysis and required mechanical ventilation after general anesthesia for achalasia treatment.
• This event occurred despite a successful endoscopic pneumatic dilation procedure.
• The patient ultimately recovered fully without further complications.

Findings:

• Pseudocholinesterase deficiency prolongs paralysis from succinylcholine and mivacurium.
• A detailed patient history, including family history of anesthesia complications, is vital for risk identification.
• This case highlights the importance of recognizing and managing pseudocholinesterase deficiency in clinical practice.

Implications:

• Proceduralists and anesthesia staff must be aware of pseudocholinesterase deficiency risks.
• Screening for family history of anesthesia complications can identify at-risk patients.
• Prompt recognition and management can prevent severe postoperative complications and ensure patient safety.
