Side effects of etomidate in dogs
1Department of Veterinary Clinical Sciences, College of Veterinary Medicine, Ohio State University, Columbus 43210-1089.
Summary
Pre-administering diazepam, acepromazine, or morphine significantly reduced side effects like excitement and muscle movements in dogs receiving etomidate anesthesia. This improves etomidate safety in veterinary medicine.
Area of Science:
- Veterinary Anesthesiology
- Pharmacology
Background:
- Etomidate is a nonbarbiturate sedative hypnotic used for anesthesia.
- Intravenous etomidate administration can cause adverse effects during induction and recovery in dogs.
Purpose of the Study:
- To evaluate the side effects of etomidate in dogs.
- To determine if pre-treatment with other drugs can mitigate these side effects.
Main Methods:
- Intravenous etomidate was administered to 20 experimental and 70 hospitalized dogs.
- Side effects were recorded during induction and recovery.
- Dogs received diazepam, acepromazine, or morphine prior to etomidate in some cases.
Main Results:
- Etomidate induced excitement, myoclonus, pain, vomiting, and apnea in dogs.
- Excitement and muscle movements were observed during recovery.
- Pre-treatment with diazepam, acepromazine, or morphine markedly reduced or eliminated these side effects.
Conclusions:
- Etomidate administration is associated with significant side effects in dogs.
- Pre-treatment with diazepam, acepromazine, or morphine effectively attenuates etomidate-induced adverse effects.
- These findings support strategies to improve the safety profile of etomidate in canine anesthesia.
