摘　　要：目的探讨不同4.0%水合氯醛给药方式的孕羊麻醉方案,在胎羊宫内心脏介入手术中的效果,旨在为胎儿宫内心脏介入手术麻醉方案提供依据。方法将40只孕龄为110~127d的孕羊,按照随机数字表法,将其随机分为滴注组（4.0%水合氯醛持续静脉滴注）及推注组（4.0%水合氯醛负荷给药后间断静脉推注）,每组20只孕羊。观察两组实验孕羊的麻醉显效、复苏时间及麻醉状态能否满足手术要求,记录镇静剂总量,检测术前及术后2个时间点孕羊心率、平均动脉压（MAP）、血pH值、动脉血氧分压（PaO2）、动脉血二氧化碳分压（PaCO2）、血糖、血乳酸、肾上腺素、去甲肾上腺素及皮质醇10项指标水平变化。比较两组孕羊麻醉效果差异,以及在不同组别及不同时间点上述10项指标的水平差异。两组孕羊体质量及孕龄比较,差异无统计学意义（P〉0.05）。结果 1两组孕羊麻醉方案比较,术前肌内注射给药、麻醉给药途径、麻醉维持时间及呼吸道控制情况等方面均相同,两组孕羊麻醉方案均能满足胎羊宫内心脏介入手术要求,但滴注组对麻醉深浅的控制稍难。两组孕羊麻醉最快显效时间及术后开始复苏时间比较,差异均无统计学意义（P〉0.05）。滴注组氯胺酮剂量小于推注组[（116.3±22.5）mg vs（209.3±20.8）mg],而4.0%水合氯醛及地西泮剂量则大于推注组[（216.7±39.7）mL vs（165.4±19.5）mL,（19.2±3.4）mg vs（10.1±2.9）mg],孕羊术后完全复苏时间长于推注组[（273.5±26.2）min vs（191.9±33.1）min],且差异均有统计学意义（P〈0.05）。2术前两组孕羊上述10项指标水平比较,差异均无统计学意义（P〉0.05）。滴注组孕羊术后血乳酸、肾上腺素、去甲肾上腺素及皮质醇含量较术前增高[分别为（6.0±0.8）mmol/L vs（3.7±0.6）mmol/L,（626.3±99.4）ng/L vs（167.3±35.4）ng/L,（6 631.9±753.2）ng/L vs（1 938.5±393.3）ng/L,（509.0�Objective To explore the effects of different 4.0% chloral hydrate administered modes of anesthesia for pregnant goat during fetal goat intrauterine cardiac intervention program to provide basis of anesthesia for fetal intrauterine cardiac intervention program.Methods A total of 40 pregnant goats who were being pregnant for 110-127 d were divided into infusion group（4.0% chloral hydrate continuous intravenous infusion）and injection group（4.0% chloral hydrate intermittent intravenous injection after load）in accordance with random digits table,and each group contained 20 pregnant goats.To observe anesthesia effect and recovery time,and whether anesthesia state could meet the operation requirements or not of two groups of pregnant goats,recorded total sedative dose.Detected 10 kinds of indicators including heart rate,mean arterial blood pressure（MAP）,blood pH value,arterial partial pressure of oxygen（PaO2）,arterial partial pressure of carbon dioxide（PaCO2）,blood glucose,blood lactic acid,epinephrine,norepinephrine and cortisol of pregnant goats at 2time points of preoperative and postoperative.Compared difference of anesthesia effect between two groups and differences of these 10 kinds of indicators between different groups and time points.There were no significant differences between two groups in pregnant goat body mass and gestational age（P〉0.05）.Results 1Comparison of anesthesia between two groups,preoperative intramuscular injection medicine,route of administration,duration of anesthesia and airway control were all the same,both two kinds of anesthesia could meet the requirements of intrauterine intervention for fetal goat,but there were slightly difficult for infusion group to control anesthesia depth.There were no significant differences between two groups in anesthesia effective time and postoperative starting recovery time（P〉0.05）.Ketamine doses in infusion group was less than injection group[（116.3±22.5）mg vs（209.3±20.8）mg],while 4.0% chloral hydrate and diazepam d
