What is the dosage of etomidate recommended for induction?

The recommended dosage of etomidate for induction of anesthesia is typically in the range of 0.2 to 0.3 mg/kg. The choice of 0.3 mg/kg reflects a balance that often provides rapid onset with effective sedation while minimizing side effects. At this dosage, etomidate works well to induce anesthesia quickly, which is particularly useful in emergency situations where time is critical.

Etomidate is favored for its hemodynamic stability and minimal effects on cardiovascular function, making it a good choice for patients at risk of cardiovascular issues. The range of 0.2 to 0.3 mg/kg allows for flexibility depending on the clinical scenario and individual patient needs while ensuring adequate induction is achieved.

Dosing lower than 0.2 mg/kg may not provide sufficient anesthetic depth, while doses higher than 0.3 mg/kg could increase the risk of side effects or prolonged sedation. Thus, 0.3 mg/kg is considered an effective and commonly used dose for induction in many clinical settings.
