盐酸氯胺酮(Ketamine)是一种新型非巴比妥类麻醉药物,为苯环己哌啶的衍生物,化学结构为2-(0-氯苯)-2-(甲胺)环己酮盐酸盐(图1)。它是一种白色结晶,熔点259℃,可溶于水成20%的无色溶液。10%水溶液的PH为3.5。动物实验证明有强大的催眠和镇痛作用,但对呼吸和循环系统无明显影响。目前国外用氯胺酮单独麻醉、诱导麻醉 Ketamine hydrochloride is a new non-barbituse anesthetic and is a derivative of phencyclidine. Its chemical structure is 2- (0-chlorophenyl) -2- (methylamine) cyclohexanone hydrochloride Salt (Figure 1). It is a white crystalline, melting point of 259 ° C, soluble in water to 20% of the colorless solution. The 10% aqueous solution had a pH of 3.5. Animal experiments have shown a strong hypnotic and analgesic effect, but no significant effect on the respiratory and circulatory system. At present foreign ketamine alone anesthesia, induction of anesthesia
