Study on the Determination of Administration Time and Dosage of Chloral Hydrate Required to Produce Deep Anesthesia in Calves

자우(仔牛)에 있어서 심마취기도달(深麻醉期到達)에 요구(要求)되는 Chloral Hydrate의 투여시간(投與時間) 및 용량측정(用量測定)에 관(關)하여

Ten calves were subjected to general anesthesia with ten percent chlooral hydrate solution. The drug was administered by the method of slow intravenous injection so as to have a better control over the dosage and time until deep anesthesia was attained. Although one of ten calves failed to produce anesthesia, the remainder of nine responded satisfactorily with deep anesthesia. The dosage required averaged as great as 17.5gm per calf, and the time 23 minutes. In view of these advantages indicated in the results, further studies on the use of intravenous chloral hydrate for deep anesthesia in bovine species are to be justifiable.
