[Electroconvulsive Therapy (ECT) in Neuroleptic Malignant Syndrome (NMS) on an Intensive Care Unit (ICU)]

A 57-year-old female patient with unclear somnolence was admitted to an Intermediate Care Unit (IMC) by an emergency physician. Several psychotropic drugs were on the medication list (quetiapine 450 mg/d, paroxetine 40 mg/d and perphenazine 12 mg/d), due to depression with psychotic features. As the patient's state deteriorated on day 3, she was intubated and transferred to Intensive Care Unit (ICU), where a malignant hyperthermia (MH) was assumed. The ICU's call to the MH hotline did not give a hint to consider a neuroleptic malignant syndrome (NMS) neither to consider electroconvulsive therapy (ECT). It was not until day 9 that a psychiatric consultation was undertaken, under the suspected diagnosis of NMS. On the same day ECT was performed, followed by a rapid remission of all clinical features and laboratory findings. Early consideration and application of ECT treatment for NMS on an ICU is life-saving.
