To evaluate the analgesic efficacy of lumbosacral intrathecal administration of 2% lidocaine in goats undergoing cesarean sections (C-sections).
7 client-owned goats.
Medical records were retrospectively reviewed to identify records of goats undergoing C-sections between January 2020 and November 2021 with intrathecal administration of lidocaine as the primary method of analgesia. Effect of analgesia, American Society of Anesthesiologists status, quality of surgery (determined based on lack of patient movement), mean surgical time, time to stand, and anesthetic complications were recorded.
Intrathecal administration of preservative-free 2% lidocaine (1 mg/kg) at the lumbosacral space with the use of a 20-gauge 3.5-inch (0.9 X 90-mm) spinal needle under aseptic technique achieved effective analgesia in sedated goats by time of skin incision. Adequacy of analgesia was complete (failure to respond to needle-prick of skin or skin incision) in 6 of the 7 goats and moderate in 1 goat. Quality of surgery was adequate in all goats. Mean surgical time was 96 ± 20 minutes, and mean time to stand was 182 ± 61 minutes from the time of intrathecal administration. Complications included ruminal tympany, hypothermia, and partial blockade in 1 goat each.
Results indicated that intrathecal administration of lidocaine as described in the present report provided adequate analgesia for C-sections in goats, with minimal complications, and quicker return to hindlimb motor function postoperatively than historically reported for epidurals.
评估 2%利多卡因腰荐椎管内给药在接受剖宫产术（C 剖）的山羊中的镇痛效果。
7 只客户所有的山羊。
回顾性查阅病历，以确定 2020 年 1 月至 2021 年 11 月间接受 C 剖并以鞘内利多卡因给药作为主要镇痛方法的山羊记录。记录镇痛效果、美国麻醉师协会状态、手术质量（基于患者无运动确定）、平均手术时间、站立时间和麻醉并发症。
在无菌技术下，使用 20 号 3.5 英寸（0.9×90mm）的 20 号椎管内针在腰荐间隙鞘内给予 1 毫克/千克的无防腐剂 2%利多卡因，可使镇静山羊在切皮时达到有效镇痛。7 只山羊中有 6 只镇痛完全（对皮肤刺痛或皮肤切口无反应），1 只中等镇痛。所有山羊的手术质量均良好。平均手术时间为 96±20 分钟，从鞘内给药到站立的平均时间为 182±61 分钟。并发症包括瘤胃鼓气、低体温和 1 只山羊的部分阻滞。
结果表明，本报告中描述的鞘内给予利多卡因可提供山羊 C 剖术的充分镇痛，并发症最小，与历史上报道的硬膜外麻醉相比，术后后肢运动功能恢复更快。
