A young adult male is brought to the inpatient psychiatric unit by his family due to a profound decline in functioning over the past two weeks. The patient has been entirely mute, persistently holds his arms in rigid, unnatural postures for hours, and refuses all oral intake. His current daily medication regimen includes risperidone and fluoxetine. Vital signs show a heart rate of and blood pressure of ; he is afebrile. The psychiatry team suspects catatonia. Arrange the following management steps in the most appropriate sequential order for evaluating and treating this patient's current condition.
- 1Discontinue risperidone therapy immediately
- 2Administer an intravenous lorazepam challenge test
- 3Initiate a scheduled regimen of high-dose lorazepam
- 4Consult for and proceed with electroconvulsive therapy (ECT)
Cevap
The correct sequential order for managing catatonia is to first discontinue the offending antipsychotic, then perform a lorazepam challenge test, followed by initiating scheduled lorazepam therapy, and finally reserving electroconvulsive therapy for refractory cases.
The standard of care for treating catatonia requires a stepwise approach to maximize safety and efficacy. The absolute first step is the cessation of dopamine-blocking agents (such as risperidone), as these can worsen the catatonic state and provoke neuroleptic malignant syndrome. Once the offending agent is removed, the diagnosis is confirmed and initially treated with a lorazepam challenge. If the patient responds, they are placed on scheduled lorazepam to maintain the therapeutic effect. Electroconvulsive therapy (ECT) is generally reserved as a last-line treatment for medication-refractory catatonia, unless the patient is actively deteriorating with malignant catatonia (fever, autonomic instability), in which case it is used earlier.
