デグーの口腔内処置を可能にするアルファキサロンを用いた皮下注射麻酔法

Abstract

This study investigated a subcutaneous injection anesthesia using 7 mg/kg alfaxalone following premedication with 0.2 mg/kg medetomidine and 2.5 mg/kg butorphanol in degus. Degus were lateral positioned after approximately 3 min and the sedative and anti-nociceptive ef fect lasted approximately 20 min. Using an oxygen mask, the percutaneous ar terial oxygen saturation (SpO2) was maintained at 99%. The body temperature, hear t rate, respirator y rate, and pulse rate were also maintained within a clinically satisfactor y range. In degus under the subcutaneous injection anesthesia, a simulated intraoral treatment proceeded smoothly without resistance and flow-by oxygen supplementation reduced hypoxia (approximately SpO2 93%). Therefore, this subcutaneous injection anesthesia is considered to be a useful anesthesia protocol that allows intraoral treatment in degus.
