Insights
Propofol (an intravenous anesthetic) can paradoxically cause myoclonic movements in susceptible patients. This case highlights the need for caution when using propofol for anesthesia induction.
Area of Science:
- Anesthesiology
- Neuroscience
Background:
- Propofol is a widely used intravenous anesthetic agent known for its sedative and hypnotic effects.
- While generally safe, rare adverse events associated with propofol administration have been reported since its introduction.
Observation:
- A case report details a 1-year-old boy undergoing adenotonsillectomy for obstructive sleep apnea.
- The patient exhibited myoclonic movements during the induction of anesthesia with propofol.
Findings:
- Despite propofol's known anticonvulsant properties, this case illustrates its potential proconvulsant effect in specific circumstances.
- The myoclonic movements ceased upon administration of isoflurane, and the patient recovered without neurological deficits.
Implications:
- Clinicians should be aware of the potential for propofol to induce abnormal movements in susceptible individuals.
- Caution or avoidance of propofol may be warranted in certain patient populations or clinical scenarios to mitigate this risk.
Objective:
To report a case of myoclonic movements during an induction of anesthesia using propofol. Abnormal movements resulting from propofol are uncommon but there have been a number of such cases since propofol was introduced.
Clinical Features:
An 1-year-old boy with a diagnosis of obstructive sleep apnea was scheduled to undergo adenotonsillectomy. He demonstrated myoclonic movements during anesthetic induction using propofol. He was then given isoflurane and his airway was secured with an endotracheal tube after full muscle relaxation by succinylcholine. The anesthetic maintenance was uneventful as was the emergence. The patient recovered smoothly without neurological deficit.
Conclusion:
Propofol, an intravenous anesthetic, with strong evidence of anticonvulsant property, could, in susceptible patients, under certain conditions, act as a proconvulsant, and should, thus, be avoided or cautiously used in some patients.
