Opioids and other analgesics. Adverse effects in the intensive care unit

Abstract

Analgesics are an important component of care for critically ill patients. The agents available--opioids, anesthetics, and NSAIDs--are efficacious, but each is capable of inducing a variety of adverse effects. Many adverse effects associated with opioid use can be minimized with the use of anticipatory measures. Anesthetic agents and NSAIDs offer less effect on cardiovascular and respiratory function than opioids, but are not without adverse effects. A thorough understanding of analgesic-associated adverse effects and drug interactions, as well as methods for anticipating and monitoring them, can help to minimize their effect on the ICU patient.
