Reduction of iatrogenic withdrawal syndrome in high-risk critically ill patients with acute respiratory distress syndrome

Abstract

Limited data suggest a subset of patients with acute respiratory distress syndrome receive high-dose and prolonged opioid and sedative infusions. With prolonged use, patients may be at risk for developing iatrogenic withdrawal syndrome after discontinuation or tapering of these agents. Iatrogenic withdrawal syndrome is well described in paediatric patients; however, limited guidance exists in adult intensive care unit patients regarding risk factors and ideal management strategies. This article discusses several weaning strategies for high-risk patients to minimise withdrawal symptoms and safely reduce or discontinue opioid and sedative infusions. Ideal weaning strategies are lacking, but several options exist. These include a gradual reduction of the agent, changing the route of delivery by switching to an enteral or parenteral longer-acting agent from the same class, and substitution to an alternative agent to help mitigate potential withdrawal symptoms. This should be accomplished through a multidisciplinary approach by involving experts from relevant specialties while closely observing for withdrawal symptoms.
