F A Eales, J Small

    The Veterinary Record
    |March 20, 1982
    PubMed
    Summary

    Alphaxalone/alphadolone provides effective anesthesia in newborn lambs via intravenous or divided intramuscular injections. Recovery is rapid and quiet, with transient cardiorespiratory changes considered clinically acceptable for this injectable anesthetic.

    Area of Science:

    • Veterinary Anesthesiology
    • Neonatal Animal Models

    Background:

    • Injectable anesthetics are crucial for procedures in neonatal animals.
    • Alphaxalone/alphadolone is a steroid-based anesthetic agent.

    Purpose of the Study:

    • To evaluate the efficacy and safety of alphaxalone/alphadolone in newborn lambs.
    • To compare intravenous and intramuscular routes of administration.

    Main Methods:

    • Administration of alphaxalone/alphadolone (12 mg/ml) via intravenous and intramuscular routes.
    • Dosing varied between 6-12 mg/kg depending on the route.
    • Assessment of anesthetic quality, recovery, and cardiorespiratory parameters.

    Main Results:

    • Effective anesthesia achieved with intravenous (6 mg/kg) and divided intramuscular (9-12 mg/kg) injections.
    • Quiet and short recovery periods observed across all effective administration routes.
    • Transient, clinically acceptable decreases in heart and respiratory rates during anesthesia.

    Conclusions:

    • Alphaxalone/alphadolone is a suitable injectable anesthetic for newborn lambs.
    • Divided intramuscular administration is superior to single intramuscular injection due to absorption.
    • Intravenous administration offers effective anesthesia at a lower dose.
