Critical Care Study Guide

Abstract

Understand the pharmacokinetics and pharmacodynamics of various sedative/hypnotics and analgesics. Be aware of the action of sedative/hypnotics and analgesics on central γ-aminobutyric acid (GABA) and opioid receptor systems. Understand the need for routine and effective sedation and analgesia in the critically ill patient. Make recommendations regarding the choice and appropriate dose of sedative/hypnotics and analgesics in the critically ill. Recognize that agitation has multiple etiologies and should be investigated as fully as possible prior to treatment. Recognize that agitated patients could pose danger to themselves and/or healthcare personnel, and pharmacologic intervention may be necessary to facilitate safe patient care.
