Strategies for a Rational Use of Opioids in Critical Care Settings

Résumé fourni par la source

Opioids play a central role in pain management and sedation in Intensive Care Units (ICUs), where critically ill patients frequently experience moderate-to-severe pain due to illness and invasive procedures or devices. Uncontrolled pain exacerbates stress responses, contributing to clinical deterioration and adverse outcomes. Although analgesics and sedatives can mitigate these effects, their use must be carefully individualized to avoid complications such as delirium, prolonged mechanical ventilation, and increased mortality. Evidence now shows that excessive or poorly controlled analgosedation can prolong ICU length of stay and delay recovery. Current guidelines recommend opioids as first-line agents for severe acute pain in the ICU, preferably within a multimodal analgesia framework to optimize pain control while minimizing adverse effects. Opioids are also essential for improving tolerance to invasive and noninvasive mechanical ventilation. Modern ICU practice emphasizes an analgesia-first or "analgosedation" strategy, prioritizing pain control with intravenous opioids before adding sedatives. This approach aims to achieve light sedation, reduce ventilator days, and improve overall outcomes. Commonly used opioids include fentanyl, morphine, hydromorphone, sufentanil, and remifentanil, with short-acting agents favored when rapid titration is required. Our narrative review aims to evaluate the clinical impact of opioid use in critically ill patients, including post-ICU outcomes, and to explore the role of opioid stewardship in optimizing patient care.
