What is the most appropriate initial intervention for a patient suspected of having neuroleptic malignant syndrome?

The most appropriate initial intervention for a patient suspected of having neuroleptic malignant syndrome (NMS) is supportive care with fluids and antipyretics. NMS is a life-threatening condition characterized by severe muscle rigidity, high fever, autonomic instability, and altered mental status, typically triggered by the use of antipsychotic medications.

In the management of NMS, the cornerstone treatment involves supportive care. This includes administering intravenous fluids to address dehydration and maintain electrolyte balance and using antipyretics to help reduce the high fever that often accompanies the syndrome. These supportive measures are vital for stabilizing the patient's condition and preventing complications.

Prompt identification and management of NMS is crucial, as the condition can progress rapidly. While other interventions, such as adjusting antipsychotic medication or considering pharmacological treatments like dantrolene or bromocriptine, may be necessary later, they are not the first line of action. Immediate supportive care takes precedence to ensure the patient is stable and their basic needs are met.

Mechanical ventilation may be warranted in severe cases with respiratory failure, but this is not the initial approach; the same applies to the use of intravenous antibiotics which are indicated only if there is a concurrent infection. Therefore, supportive care is
