What is the recommended dose range for Etomidate when used for intubation?

1. 0.1-0.2 mg/kg

2. 0.2-0.3 mg/kg

3. 0.3-0.4 mg/kg

4. 0.5-0.6 mg/kg

The correct answer is: 0.2-0.3 mg/kg

The recommended dose range for Etomidate when used for intubation is indeed between 0.2 and 0.3 mg/kg. This dosage provides an effective balance of rapid induction and hemodynamic stability, which is crucial for patients who may be compromised or have variable cardiovascular responses. Etomidate is a short-acting anesthetic agent noted for its minimal cardiovascular and respiratory effects, making it particularly useful in emergency intubation scenarios or in patients with unstable hemodynamics. The dosing range of 0.2 to 0.3 mg/kg ensures sufficient sedation and facilitates successful intubation while reducing the risk of adverse effects. Doses outside this range, such as those higher than 0.3 mg/kg, may increase the risk of side effects without providing additional benefits in terms of sedation. Lower doses may not achieve the desired sedation depth for effective intubation. Therefore, administering Etomidate within this recommended range helps ensure optimal patient outcomes during the intubation process.
