“…The induction and recovery time is likely due to the body temperature and metabolism of tortoises at the time of initial drug administration. As the sampling season progressed, ambient temperatures increased and led to faster metabolism (Douglass and Layne , Schumacher ), which directly affected drug absorption and distribution. The decrease in sampling time over the course of the study was likely a result of the handler becoming more efficient as sampling season progressed.…”

“…The physiology of chelonians creates challenges in monitoring and maintaining adequate anesthetic depth and quality. Problems typically encountered are 1) unpredictable absorption and metabolism of anesthetic drugs, 2) inconsistent depth of anesthesia and muscle relaxation, 3) prolonged recovery periods, and 4) anesthetic‐drug distribution variability associated with the renal portal system (Maxwell , Rooney et al , Mosley , Schumacher , Ziolo and Berelsen ). Therefore, despite the fact that a number of anesthetic agents are routinely utilized in chelonians, they each present specific challenges for field studies.…”

Safety and utility of an anesthetic protocol for the collection of biological samples from gopher tortoises

et al. 2013

Adult gopher tortoises (Gopherus polyphemus) are difficult to physically restrain, particularly for examination of the upper respiratory tract and oral cavity—areas important for biological sample collection during disease surveillance studies. Collection of nasal lavage is required for determining the status of Mycoplasma infection in tortoises. Anesthesia is often necessary to provide full relaxation in order to gain access to the head and mouth for nasal lavage. Therefore, deep sedation or general anesthesia are required both for the welfare of the tortoise and to maximize the usefulness of biological samples collected. The objective of this study was to assess the utility and safety of a novel field‐anesthetic combination of dexmedetomidine–ketamine–morphine (75 mc/kg; 8 mg/kg; 1 mg/kg, respectively), followed by reversal with atipamezole (0.02 mg/kg). Between May and October 2009 at the Joseph W. Jones Ecological Research Center in Baker County, Georgia, USA, 128 tortoises were captured and anesthetized with this protocol. Average time to first effects was 9.7 minutes, to induction was 21.6 minutes, to total recovery after administration of reversal was 92.7 minutes, and the mean time from administration of anesthesia through complete recovery for adult tortoises was 129 minutes but ranged from 40 minutes to 300 minutes. Clinical signs of upper respiratory tract disease significantly reduced the induction time such that tortoises with clinical signs lost consciousness faster than healthy tortoises. Study month significantly influenced the time to induction and time to recovery, such that as the study progressed, both parameters decreased. This anesthetic protocol proved to be an effective, reliable, repeatable, and safe method to collect quality biological samples from gopher tortoises. © 2013 The Wildlife Society.

Juvenile American alligators were successfully immobilized with medetomidine (0.15 mg kg −1 ) injected into the triceps muscle; with this dose the induction time ranged from 5 to 30 minutes and animals remained immobilized for 30 minutes, at which time they were administered atipamezole (0.75 mg kg −1 ) into the contralateral triceps muscle (Jalanka & Roeken 1990; Smith et al.…”

“…Local anaesthesia with lidocaine or procaine for topical anaesthesia in reptiles has been well documented (Schumacher 1996;Bennett 1998b). In conjunction with a suitable agent of general anaesthesia, local anaesthesia was used for minor surgical procedures (Schumacher and Yelen 2006;Schumacher 2007;Gibbons and Klaphake 2013).…”

Combination of lidocaine/prilocaine with tramadol for short time anaesthesia-analgesia in chelonians: 18 cases

The aim of this study was the evaluation of the practical use of lidocaine/prilocaine cream as the local anaesthetic in combination with tramadol anaesthesia for the surgical treatment of prolapsed penis in chelonians. Eighteen animals were included in this study. After administration of tramadol, prolapsed penis was cleaned and disinfected. Lidocaine/prilocaine cream at a dose of 1g/10 cm 2 was applied on the penile mucosa. The time interval from lidocaine/prilocaine application to a loss of hind limb withdrawal reflex and the response to penile mucosa pinching was recorded as the induction time for surgical anaesthesia. The time interval from lidocaine/ prilocaine application to full restoration of tail and hind limb withdrawal reflex was recorded as the recovery time. In two male chelonians the response to pain stimuli persisted for more than 20 min after lidocaine/prilocaine cream application, and the anaesthetic cream had to be re-administered. After this second application of lidocaine/prilocaine cream, surgical anaesthesia was reached within 28 and 32 min. The mean induction time for surgical anaesthesia was 19.22 ± 4.36 min. The mean recovery time was 40.83 ± 7.68 min. In all 18 male chelonians the surgical treatment of prolapsed penile was uneventful. Topical application of lidocaine/prilocaine cream can be used as a feasible form of local anaesthesia in combination with tramadol analgesia management for minor surgical procedures in chelonians.
