Etomidate is indicated by intravenous injection for the induction of general anesthesia. When considering use of Etomidate, the usefulness of its hemodynamic properties should be weighed against the high frequency of transient skeletal muscle movements. Intravenous Etomidate is also indicated for the supplementation of subpotent anesthetic agents, such as nitrous oxide in oxygen, during maintenance of anesthesia for short operative procedures such as dilation and curettage or cervical conization.
Dosage & Administration
Etomidate injection is intended for administration only by the intravenous route. The dose for induction of anesthesia in adult patients and in pediatric patients above the age of ten (10) years will vary between 0.2 and 0.6 mg/kg of body weight, and it must be individualized in each case. The usual dose for induction in these patients is 0.3 mg/kg, injected over a period of 30 to 60 seconds. There are inadequate data to make dosage recommendations for induction of anesthesia in patients below the age of ten (10) years; therefore, such use is not recommended. Geriatric patients may require reduced doses of etomidate. Smaller increments of intravenous Etomidate may be administered to adult patients during short operative procedures to supplement subpotent anesthetic agents, such as nitrous oxide. The dosage employed under these circumstances, although usually smaller than the original induction dose, must be individualized. There are insufficient data to support this use of etomidate for longer adult procedures or for any procedures in pediatric patients; therefore, such use is not recommended. The use of intravenous fentanyl and other neuroactive drugs employed during the conduct of anesthesia may alter the etomidate dosage requirements. Etomidate hypnosis does not significantly alter the usual dosage requirements of neuromuscular blocking agents employed for endotracheal intubation or other purposes shortly after induction of anesthesia. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. To prevent needle-stick injuries, needles should not be recapped, purposely bent, or broken by hand.
Do not administer unless solution is clear and container is undamaged. Discard unused portion. Pregnancy: Pregnancy Category of Etomidate is C. Etomidate should be used during pregnancy only if the potential benefit justifies the potential risks to the fetus. Labor and Delivery: There are insufficient data to support use of intravenous etomidate in obstetrics, including Caesarean section deliveries. Therefore, such use is not recommended. Nursing Mothers: It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when etomidate is administered to a nursing mother. Pediatric Use: There are inadequate data to make dosage recommendations for induction of anesthesia in patients below the age of ten (10) years; therefore, such use is not recommended. Geriatric Use: Clinical data indicates that etomidate may induce cardiac depression in elderly patients, particularly those with hypertension. Elderly patients may require lower doses of etomidate than younger patients. This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection and it may be useful to monitor renal function. Plasma Cortisol Levels: Induction doses of etomidate have been associated with reduction in plasma cortisol and aldosterone concentrations. These have not been associated with changes in vital signs or evidence of increased mortality; however, where concern exists for patients undergoing severe stress, exogenous replacement should be considered. Warnings Intravenous etomidate should be administered only by persons trained in the administration of General Anesthetics and in the management of complication encountered during the conduct of General Anesthesia. Because of the hazards of prolonged suppression of endogenous cortisol and aldosterone production, this formulation is not intended for administration by prolonged infusion.
