Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Etonidate is an ultrashort-acting nonbarbiturate hypnotic agent that produces anesthesia by enhancing GABA-mediated chloride conductance at GABA-A receptors, leading to central nervous system depression.
Lidocaine is a sodium channel blocker that inhibits depolarization of cardiac myocytes and nerve axons by binding to voltage-gated sodium channels and stabilizing the neuronal membrane, thereby preventing the propagation of action potentials.
2-10 mL of a 1-2% solution, subarachnoid injection, single dose only.
Intravenous infusion: 1-4 mg/min (20-50 mcg/kg/min) for cardiac arrhythmias. Bolus: 1-1.5 mg/kg IV, then infusion.

Terminal elimination half-life is 4.5 hours (range 3-6 hours). Clinical context: Prolonged in severe hepatic impairment but not significantly in renal impairment.
Terminal elimination half-life approximately 1.5-2 hours after bolus, prolonged to 2-4 hours in heart failure or hepatic impairment; continuous infusion may show context-sensitive half-life.
Primarily hepatic metabolism; renal excretion of metabolites accounts for <10% unchanged drug. Biliary/fecal elimination is minimal.
Renal excretion of unchanged drug and metabolites; <10% unchanged in urine, >90% as metabolites (primarily monoethylglycinexylidide and glycinexylidide). Biliary/fecal elimination minimal (<1%).
