Official title

Effect of Ketamine and Etomidate During Rapid Sequence Intubation on Long- Term Outcomes (Long-Term Outcomes of the RSI Trial)

Overview

The RSI-LTO study collects long-term outcomes from the RSI trial (NCT05277896). One-third of adults who are intubated in the ED or ICU experience symptoms of posttraumatic stress disorder (PTSD). PTSD is a psychiatric disorder triggered by a "shocking, scary, or dangerous event." Critical illness, tracheal intubation, and mechanical ventilation can be traumatic and distressing events. Patients may recall the intubation procedure, the feeling of the breathing tube in their throat, or being unable to move ("paralyzed"). While on the breathing machine, patients may experience delirium, frightening hallucinations, and delusions. Patients with PTSD after critical illness can be hypervigilant, anxious, and troubled by intrusive thoughts, nightmares, and flashbacks that last months to years after critical illness and that PTSD negatively impacts patients' marriages, work, and quality of life and increases patients' risk of depression, anxiety, substance use disorder, and suicide. Ketamine may prevent PTSD symptoms by blocking the pathways in the brain's glutaminergic system that are responsible for the formation of traumatic memories In outpatients with chronic PTSD, a single dose of ketamine has been shown to reduce PTSD symptoms for up to 2 weeks. Even a modest reduction in PTSD would translate into tens of thousands of fewer cases of PTSD each year, more cases of PTSD each year than any other medical intervention evaluated to date.

Interventions

  • Drug Ketamine
    The RSI-LTO study collects long-term outcomes from the RSI trial (NCT05277896). In the RSI trial, patients in the ketamine group will be assigned to receive intravenous ketamine for induction of anesthesia during tracheal intubation. A dose of 2 mg/kg will be recommended, and the group assignment sheet will contain a nomogram providing the recommended dose for a range of patient weights (in pounds and kg). Treating clinicians will be able elect to give a lesser or greater dose of ketamine than r
  • Drug Etomidate
    The RSI-LTO study collects long-term outcomes from the RSI trial (NCT05277896). In the RSI trial, patients in the etomidate group will be assigned to receive intravenous etomidate for induction of anesthesia during tracheal intubation. A dose of 0.3 mg/kg will be recommended, and the group assignment sheet will contain a nomogram providing the recommended dose for a range of patient weights (in pounds and kg). Treating clinicians will be able elect to give a lesser or greater dose of etomidate t
