“…Concerning the effects of IV propofol on the cardiovascular system, previously, a stable level and even a decrease in HR have been reported in most reptiles [8,11,12,[39][40][41] except in the case of Bertelsen et al [39], which is consistent with our study and those on dogs and cats [42][43][44]. In most individuals, we observed an increase in heart rate, independent of the propofol dose that was used, after administration, even though our T0 was considered to be the moment of propofol administration.…”

This study compares the effects of two different doses of propofol administered intravenously (IV), in the jugular vein, to red-eared sliders (Trachemys scripta elegans). In this crossover study, 5 or 10 mg/kg propofol was administered to six Trachemys scripta elegans after cannulation of the jugular vein. Each turtle received each dose, G1 (5 mg/kg IV) and G2 (10 mg/kg IV), after a 7-day washout period. The parameters evaluated were heart rate, palpebral reflex, cloacal reflex, muscle relaxation, ease of handling, sensitivity to anterior and posterior pinch stimuli, and possibility of intubation. Additionally, respiratory rate was measured when possible, and the times from propofol administration to full recovery and from intubation to extubation were recorded. None of the turtles in G1 could be intubated, and this dose provided little relaxation and ease of handling, with a duration of effect until full recovery of 12.16 ± 8.32 (SD) min for this group. In G2, five out of the six turtles could be intubated, and the duration of effect was 32.33 ± 5.85 (SD) min. Heart rates were influenced by manipulation for catheter placement. There were statistically significant differences (p value ≤ 0.05) between the two groups in muscle relaxation degree, handling, cloacal reflex, and possibility of intubation. The 5 mg/kg propofol dose was not sufficient to induce anesthesia, even when administered in the jugular vein, in red-eared sliders. A dose of 10 mg/kg IV or higher should be used.

“…Assim, como em mamíferos, a analgesia preemptiva é recomendada previamente a quaisquer procedimentos dolorosos, incluindo administração sistêmica de opioides ou emprego de anestésicos locais. Um estudo de Perpiñán (2018) demonstrou resultados positivos com o uso de metadona (3-5 mg/kg SC/IM a cada 24 horas) em quelônios. Neste caso, foi adicionada metadona na dose de 1 mg/kg ao protocolo, a fim de promover analgesia preemptiva.…”

Os quelônios estão gradativamente mais presentes na rotina de animais não convencionais em clínicas, centros e hospitais veterinários, demandando vasto conhecimento de profissionais capacitados para promover um atendimento especializado. De tal maneira, a anestesia de répteis se torna ainda mais desafiadora, uma vez que diferenciadas são suas características anatômicas e fisiológicas quando comparadas aos demais grupos animais. O presente trabalho teve como objetivo relatar as técnicas e procedimentos anestésicos empregados em um exemplar de Jabuti-piranga (Chelonoidis carbonaria), de 10 anos, pesando 1,54 kg. O quelônio foi submetido a plastrotomia e enterotomia para remoção de corpos estranhos. Em sua anamnese, foi constatado que o animal apresentava prolapso peniano, constipação e um severo quadro de tenesmo há quatro dias. Pela avaliação radiográfica, foram evidenciadas cinco estruturas radiopacas, amorfas e irregulares em região cólica, que variavam de 2,04cm a 0,50cm, e que após tentativa mal sucedida de tratamento conservador, optou-se por tratamento cirúrgico. Como medicação pré-anestésica, fez-se o uso de dexmedetomidina (30 ug/kg), metadona (1 mg/kg), dextrocetamina (10 mg/kg) e midazolam (1 mg/kg). Posteriormente, a indução foi realizada com propofol (2,5 mg/kg) no seio venoso subcarapacial prosseguindo-se com acesso venoso na veia jugular com cateter 24G e administração de bolus intravenoso de propofol (5 mg/kg). Após relaxamento muscular, o animal foi intubado utilizando-se uma sonda endotraqueal número 2,0 (sem cuff) e infusão contínua de propofol em taxa variável para manutenção anestésica. A analgesia transoperatória foi executada por meio do bloqueio epidural coccígeo com lidocaína sem vasoconstritor (0,2 mL/5 cm de carapaça). Dentre os parâmetros fisiológicos monitorados, destaca-se a frequência cardíaca e respiratória, capnografia e temperatura cloacal, quais mantiveram-se estáveis durante todo o período anestésico. Ao final do procedimento, a dexmedetomidina e o midazolam foram revertidos com atipamezole (0,03 mg/kg) e flumazenil (0,01 mg/kg), respectivamente. Sua extubação ocorreu 20 minutos após o término do procedimento cirúrgico e sua recuperação pós-anestésica foi sem intercorrências.

“…The entire procedure took about five minutes for each specimen and throughout the procedure the animals showed no signs of stress. Following the example for cloacoscopy in other reptiles (Perpiñán, 2018;Morici et al, 2017;Divers, 2014), we did not sedate the lizards as cloacoscopy is considered a 'non-risky' procedure for reptiles and anaesthesia poses greater risks for reptiles compared to mammals. After the procedure, all the animals were hospitalised and monitored for 24 h. These ethically approved procedures were undertaken as routine clinical practice with the owner's permission.…”

A rigid endoscope was used to examine the cloacae of an adult pair of Tiliqua gigas gigas, and single specimens of Tiliqua gigas evanescens and Tiliqua sp. (Irian Jaya form). Throughout the procedure the animals showed no signs of stress. Clear anatomical differences were observed between the sexes. Females presented the typical two pairs of papillae (ureteral and genital) and males a single pair of urogenital papillae. The observed differences were confirmed when both pairs bred successfully in the following year.
