Effect of Push-Dose Adrenaline on Peri-intubation Hypotension During Rapid Sequence Intubation in the Emergency Department

Starting soon · Phase 4 · Has a placebo group

Conditions studied: Peri-intubation Hypotension

In brief

Rapid sequence intubation is commonly performed in the emergency department to secure the airway of critically ill patients. However, blood pressure may decrease during or shortly after intubation because of the patient's underlying illness, the effects of induction medications, and the transition to positive-pressure ventilation. This complication is known as peri-intubation hypotension and is associated with worse clinical outcomes. This study will evaluate whether a preemptive low dose of intravenous adrenaline, also known as epinephrine, can reduce peri-intubation hypotension in adult emergency department patients undergoing rapid sequence intubation. Participants will be randomly assigned to receive either 10 mcg of intravenous adrenaline or 1 mL of 0.9% sodium chloride placebo immediately before induction. The study will compare hemodynamic changes, vasopressor requirements, safety outcomes, and mortality between the two groups.
