A 62-year-old, 70-kg male is admitted to the ICU for severe septic shock secondary to pneumonia. He is on assist-control ventilation and a norepinephrine infusion titrated to maintain a MAP of 75 mm Hg via a central venous catheter. Despite receiving propofol at 50 mcg/kg/min, he remains agitated (RASS +2) and dyssynchronous with the ventilator. His labs are notable for albumin 2.0 g/dL and creatinine 1.0 mg/dL. He has received 8 L of IV fluids over the past 12 hours. Considering the patient’s clinical status and relevant pharmacokinetic alterations, which of the following is the MOST appropriate immediate pharmacotherapy adjustment to achieve adequate sedation?

A 65-year-old man with acute respiratory failure is in the ICU. He is managed with assist-control mechanical ventilation (PEEP 5 cm H₂O, FiO₂ 0.4) via a central venous catheter. For the past 72 hours, he has been receiving continuous infusions of propofol 50 mcg/kg/min and fentanyl 100 mcg/hr. His Richmond Agitation-Sedation Scale (RASS) score is consistently –4. Hemodynamics are stable and oxygenation is improving, but spontaneous breathing trials have been unsuccessful due to profound sedation. Which of the following interventions is most appropriate to facilitate liberation from mechanical ventilation?

A 68-year-old man is in the intensive care unit for severe sepsis with multi-organ dysfunction. He is mechanically ventilated on assist-control mode (FiO₂ 0.6, PEEP 10 cmH₂O) and requires a continuous norepinephrine infusion at 0.1 mcg/kg/min via a central line. For the past 72 hours, he has been maintained on a continuous propofol infusion at a deep level of sedation (RASS –4 to –5) to facilitate ventilator synchrony. This deep sedation strategy is associated with increased risk for ICU-acquired weakness, ventilator-associated pneumonia, and prolonged ICU length of stay. Which of the following interventions is MOST appropriate to mitigate the risks associated with this patient’s sedation strategy?

A 65-year-old man is admitted to the ICU with acute cardiogenic shock and severe pulmonary edema. He remains hypotensive on norepinephrine and is in worsening respiratory distress despite noninvasive positive pressure ventilation. The team decides to perform rapid-sequence induction and intubation for invasive mechanical ventilation. Which induction agent is most appropriate to minimize additional hemodynamic compromise during intubation?

A 65-year-old man with severe pneumonia is intubated and mechanically ventilated on assist-control mode. He has a central line for a norepinephrine infusion to maintain mean arterial pressure and is also receiving a continuous propofol infusion. During evening rounds, his Richmond Agitation-Sedation Scale (RASS) score is –4 (unresponsive to verbal stimuli) and he has been difficult to synchronize with the ventilator. Which of the following is the most appropriate intervention for this patient’s sedation management at this time?

A 62-year-old man with severe sepsis and acute respiratory distress syndrome is managed in the intensive care unit. He is on assist-control mechanical ventilation with a continuous propofol infusion at 30 mcg/kg/min and a norepinephrine infusion via a right internal jugular central line. His Richmond Agitation-Sedation Scale (RASS) score has been consistently –4 to –5 for the past 48 hours. During evening rounds, the clinical team notes challenges in assessing his neurological status and readiness for ventilator weaning due to prolonged deep sedation. Which of the following sedation management strategies is most appropriate to implement for this patient?

A 62-year-old man is admitted to the medical ICU for severe pneumonia requiring mechanical ventilation on pressure support mode. He has a right internal jugular central line and is receiving continuous infusions of propofol at 50 mcg/kg/min and fentanyl at 100 mcg/hour. On morning rounds, the bedside nurse reports a Richmond Agitation-Sedation Scale (RASS) score of –4 (deep sedation). This oversedation has prevented successful spontaneous breathing trials and delirium assessments for the past 48 hours. He is unable to follow commands, open his eyes, or maintain eye contact. His vital signs are stable, and his Critical-Care Pain Observation Tool (CPOT) score is 0. Which of the following is the most appropriate immediate intervention?

A 65-year-old, 80-kg man is admitted to the intensive care unit following severe sepsis with multi-organ dysfunction. He is on assist-control ventilation and receiving a norepinephrine infusion at 0.1 mcg/kg/min via a central line to maintain a mean arterial pressure of 65 mm Hg (current blood pressure 98/60 mm Hg). He also has acute kidney injury requiring continuous renal replacement therapy (CRRT). Despite adequate analgesia with a fentanyl infusion at 1.5 mcg/kg/h, he remains agitated (Richmond Agitation-Sedation Scale [RASS] +3), frequently pulling at his endotracheal tube. A target sedation level of RASS –1 to 0 has been established to facilitate ventilator weaning and prevent self-extubation. Considering the patient’s ongoing agitation, the need for light sedation, and the presence of AKI on CRRT, which of the following pharmacotherapy adjustments is the MOST appropriate next step?

A 48-year-old, 75 kg male with acute liver failure secondary to acetaminophen overdose is admitted to the ICU. He is intubated on assist-control ventilation and receiving a continuous propofol infusion at 50 mcg/kg/min and fentanyl at 75 mcg/hr via central venous catheter. Norepinephrine is titrated at 0.05 mcg/kg/min to maintain a MAP of 78 mmHg. Over 24 hours, his hepatic encephalopathy has improved from Grade IV to Grade II. His current RASS score is –3 (moderate sedation), and the target RASS is –2 to 0 (light sedation). He now opens his eyes spontaneously and follows commands inconsistently. Given his improving neurological status and hemodynamic stability, which is the MOST appropriate next step in de-escalating sedation therapy?

A 68-year-old man is admitted to the ICU with acute respiratory failure from severe community-acquired pneumonia. He is on assist-control mechanical ventilation and receiving norepinephrine at 0.05 mcg/kg/min to maintain a MAP >65 mmHg. Despite adequate fentanyl infusion, he remains agitated with a RASS score of +3, frequently pulling at his endotracheal tube. The sedation goal is a RASS of –1 to 0. Which sedative agent is most appropriate to initiate?
