Study Notes
Etomidate Overview
- General anesthetic and sedative used for rapid induction of anesthesia.
- Minimum cardiovascular effects make it suitable for high-risk patients.
Mechanism of Action
- Short-acting, nonbarbiturate anesthetic.
- Facilitates quick onset of anesthesia.
Indications
- Primarily indicated for Rapid Sequence Intubation (RSI) to facilitate endotracheal intubation.
Contraindications
- Not to be used in patients with a known hypersensitivity to Etomidate.
Precautions and Warnings
- Inhibits adrenal steroid production effectively for up to 8 hours, and longer (up to 24 hours) in elderly or debilitated patients.
- Can worsen heart failure symptoms; caution is advised in these patients.
- Use with caution in those with renal failure; renal function assessment is recommended.
- Consider halving the dose in elderly patients or those suspected to be in shock to mitigate cardiac depressive effects.
Adverse Reactions
- Common adverse reactions include nausea and vomiting.
- Other side effects may include hiccups and adrenal suppression.
Drug Interactions
- Contraindicated in patients taking benznidazole or metronidazole due to potential adverse reactions.
Dosage and Route
- Standard dosage is 0.3 mg/kg given intravenously or intraosseously, with a maximum single dose capped at 30 mg.
- Adjusted dosage of 0.15 mg/kg recommended for elderly patients, those in shock, or those at risk of hypotension due to an increased shock index.
