The popularity of tortoises kept in captivity is increasing and has caused concern regarding the necessity to establish safe and straightforward anaesthesia for those reptiles.
This study aimed to compare four protocols using levobupivacaine in spinal anaesthesia for the blockade of the caudal neuraxis of red-footed tortoises ().
Twenty-four tortoises were randomly assigned into four groups: G1, levobupivacaine 0.75% (1.15 mg kg); G2, levobupivacaine 0.37% (1.15 mg kg); G3, levobupivacaine 0.75% (2.3 mg kg); and G4, levobupivacaine 0.75% (0.1 ml 5 cm of straight carapace length). Tortoises were evaluated for respiratory rate, muscle relaxation, response to hindlimb or tail pinch, and cloacal reflex.
A 1.15 mg kg dose of levobupivacaine 0.37% appears adequate for shorter procedures, whereas a 1.15 mg kg dose of levobupivacaine 0.75% should be appropriate for longer procedures in red-footed tortoises.
Our results are the first to show the effects of levobupivacaine on spinal anaesthesia in reptiles. Weight-based doses presented more intense and more homogeneous effects than carapace length-based doses in red-footed tortoises. Spinal anaesthesia of red-footed tortoises was safe and effective with any of the weight-based protocols.
圈养陆龟的普及度不断增加，这引发了人们对于有必要为这些爬行动物建立安全且简单的麻醉方案的关注。
本研究旨在比较四种使用左旋布比卡因的方案在对红腿陆龟（）的尾部脊神经阻滞的椎管内麻醉中的应用。
24 只陆龟被随机分为四组：G1 组，左旋布比卡因 0.75%（1.15mg/kg）；G2 组，左旋布比卡因 0.37%（1.15mg/kg）；G3 组，左旋布比卡因 0.75%（2.3mg/kg）；G4 组，左旋布比卡因 0.75%（0.1ml/5cm 直线甲壳长度）。评估陆龟的呼吸频率、肌肉松弛程度、对后肢或尾巴捏夹的反应以及泄殖腔反射。
1.15mg/kg 剂量的左旋布比卡因 0.37%似乎适用于较短的手术，而 1.15mg/kg 剂量的左旋布比卡因 0.75%则适用于红腿陆龟较长的手术。
我们的研究结果首次展示了左旋布比卡因在爬行动物椎管内麻醉中的作用。基于体重的剂量比基于甲壳长度的剂量在红腿陆龟中产生了更强烈且更均匀的效果。任何一种基于体重的方案都可安全有效地用于红腿陆龟的椎管内麻醉。
