Management of intensive care unit withdrawal syndrome

Abstract

Intensive care unit (ICU) patients frequently develop physical and psychological dependence on analgesic and sedative medications, which can lead to Iatrogenic withdrawal syndrome (IWS) upon discontinuation or tapering. The incidence of IWS in adult ICU patients varies significantly, with reported rates ranging from 12% to 100%. Identified risk factors for IWS include advanced age, obesity, medication dosage, and duration of exposure. The clinical manifestations of IWS are varied and include increased excitability of the central nervous system, gastrointestinal disturbances, and sympathetic nervous system hyperactivity. Preventive and therapeutic strategies for IWS encompass individualized medication regimens, structured withdrawal protocols, and a combination of pharmacological and non-pharmacological interventions. This review emphasizes the critical need for heightened awareness and improved management strategies to mitigate the incidence of IWS in ICU patients.
