A technique for continuous caudal epidural anesthesia in the horse was developed in trials involving 8 healthy adult horses. The injection site was the first intercaudal (intercoccygeal) space. A Huber point directional needle (Tuohy or Hustead) with a stylet was preplaced into the epidural space, used as a guide for an epidural catheter, and then removed, leaving the catheter in situ in the epidural space. A 2% solution of lidocaine hydrochloride was used as the anesthetic agent at an initial dose of 8 ml for an adult animal (474 kg to 560 kg). Repeated 4-ml doses were administered immediately upon return of sensation. The technique was found to be easily performed and effective for prolonged caudal epidural anesthesia in the horse.
在涉及8匹健康成年马的试验中，开发了一种用于马的连续尾骶硬膜外麻醉技术。注射部位是第一尾椎间隙（尾骨间间隙）。将带有芯丝的休伯尖定向针（图伊针或赫斯特德针）预先置入硬膜外腔，用作硬膜外导管的引导，然后取出，将导管留在硬膜外腔原位。使用2%盐酸利多卡因溶液作为麻醉剂，成年动物（474千克至560千克）的初始剂量为8毫升。感觉恢复后立即重复给予4毫升剂量。结果发现该技术易于实施，对马的长时间尾骶硬膜外麻醉有效。
