SUMMARY:

Much of the clinical and surgical casuistry in tortoises requires anesthetic procedures, including locoregional anesthesia, a technique where local anesthetics are used with the aim of blocking a region, preventing the transmission of the painful stimulus. It is a technique that promotes trans-surgical pain block, reduces anesthetic requirements, promotes greater cardiovascular stability, provides rapid recovery and, depending on the choice of drug, can promote long postoperative analgesia. Among the locoregional anesthesia techniques, epidural anesthesia stands out, however, before local anesthetics are used epidural ly, It is Contrast studies are carried out with the aim of discovering the most suitable volume to produce anesthetic block in a given area. Contrast dispersion can be assessed using the epidurography technique, after injection of low osmolarity contrast and radiographic imaging. The objective of the present study wasevaluate the use of peripheral nerve stimulator in localizing the epidural space and the dispersion of radiographic contrastio hexolusing the epidurography technique on tortoise (Chelonoides carbonaria). Were selected 12 adult male animals, with an average weight of 4.37 kg and an average carapace length of 39.58 cm. In the single treatment, 0.2 ml of iohexol contrast was used for every 5 cm of carapace. After performing antisepsis of the skin in the dorsal region of the tail, the intervertebral space closest to the carapace was located and access was performed with an electrode needle. Spinal radiography was performed at times 0 and 25 minutes after injection of contrast into the epidural space, in the left latero-lateral view. With the aid of digitalized radiographic images, assessments were made of the cranial progression of the contrast, associated with the location of the locoregional anesthetic block. Of the 12 animals evaluated, 8 (66.6%) had their epidural spaces correctly accessed, among them 3 animals showed contrast progression up to the sacrum, 3 showed progression up to the 18th presacral vertebra, 1 animal showed contrast up to the 13th vertebra presacral, 1 presented contrast in the 1st caudal vertebra and 4 presented absence of contrast in the epidural space, which was found in the subcutaneous space or in the circulatory system. It was considered that the use of ENP helped in the procedure for locating the epidural space, however a comparative study between techniques with and without the use of the device is recommended. Furthermore, the study demonstrated efficient cranial progression, with the volume considered ideal for anesthetic block of the hind limbs.
