Prevalence and Risk Factors for Iatrogenic Opioid Withdrawal in Medical Critical Care Patients

Management of sedation during weaning from mechanical ventilation

PURPOSES OF REVIEW

Critically ill patients frequently require mechanical ventilation and often receive sedation to control pain, reduce anxiety, and facilitate patient-ventilator interactions. Weaning from mechanical ventilation is intertwined with sedation management. In this review, we analyze the current evidence for sedation management during ventilatory weaning, including level of sedation, timing of sedation weaning, analgesic and sedative choices, and sedation management in acute respiratory distress syndrome (ARDS).

RECENT FINDINGS

Despite a large body of evidence from the past 20 years regarding the importance of light sedation and paired spontaneous awakening and spontaneous breathing trials (SATs/SBTs) to promote ventilator weaning, recent studies show that implementation of these strategies lag in practice. The recent WEAN SAFE trial highlights the delay between meeting weaning criteria and first weaning attempt, with level of sedation predicting both delays and weaning failure. Recent studies show that targeted interventions around evidence-based practices for sedation weaning improve outcomes, though long-term sustainability remains a challenge.

SUMMARY

Light or no sedation strategies that prioritize analgesia prior to sedatives along with paired SATs/SBTs promote ventilator liberation. Dexmedetomidine may have a role in weaning for agitated patients. Further investigation is needed into optimal sedation management for patients with ARDS.

Optimal strategies for assessing and managing pain, agitation, and delirium in the critically ill surgical patient: What you need to know

ABSTRACT

Pain, agitation, and delirium (PAD) are primary drivers of outcome in the ICU, and expertise in managing these entities successfully is crucial to the intensivist's toolbox. In addition, there are unique aspects of surgical patients that impact assessment and management of PAD. In this review, we address the continuous spectrum of assessment, and management of critically ill surgical patients, with a focus on limiting PAD, particularly incorporating mobility as an anchor to ICU liberation. Finally, we touch on the impact of PAD in specific populations, including opioid use disorder, traumatic brain injury, pregnancy, obesity, alcohol withdrawal, and geriatric patients. The goal of the review is to provide rapid access to information regarding PAD and tools to assess and manage these important elements of critical care of surgical patients.
