Abstract:
Pseudocholinesterase (PCHE) deficiency is a rare condition that results in increased sensitivity to certain medications, including the paralytic agents succinylcholine and mivacurium. PCHE deficiency typically presents when patients cannot be weaned off the ventilator because of residual paralysis. These patients require mechanical ventilation and sedation until they are strong enough to be safely extubated. This report presents the case of a 53-year-old male patient whose only known surgical and anesthetic complication was post-op nausea and vomiting and who was diagnosed with PCHE deficiency after he could not be safely extubated in the operating room (OR) after a robotic inguinal hernia repair. The patient was admitted to the ICU and successfully extubated several hours later.

At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...
