“…The prevalence of hypercapnia was not unexcepted as general anaesthesia causes dose-dependent hypoventilation. 27 No difference between the two centres was found despite IPPV was more commonly implemented at centre A. The prevalence of hypercapnia reported here is lower than the 92% previously found.…”

Objective The aim of this study was to retrospectively evaluate the success rate and perioperative complications of lumbosacral extradural anaesthesia in dogs undergoing total hip replacement. Study Design Records of dogs undergoing total hip replacement in which lumbosacral extradural anaesthesia with 0.5% levo- or bupivacaine combined with either morphine or buprenorphine were retrieved. Success rate was defined as intraoperative fentanyl consumption <1 μg/kg/h with no intravenous infusion of other analgesic drugs and no additional morphine/methadone within the first 3 hours from premedication. Prevalence of intraoperative anaesthetic and postoperative surgical complications was calculated. Results Overall, 206 dogs were included in the study. Success rate was 88.7%. Hypercapnia (75.2%), hypotension (46.1%), hypothermia (27.7%) and regurgitation (6.3%) were recorded during anaesthesia. Within 24 hours post-surgery, urinary retention (17.8%), vomiting/regurgitation/diarrhea (8.2%) and sciatic neurapraxia of the operated limb (5.8%) were recorded. Luxation of the operated hip occurred at 48 and 72 hours after surgery in two dogs and one dog respectively. One dog had cardiopulmonary arrest at 52 hours after surgery. Conclusion While hypercapnia, hypotension and hypothermia might develop intraoperatively, the high success rate and the relatively low prevalence of postoperative surgical complications directly associated with lumbosacral extradural anaesthesia justify its use in dogs undergoing total hip replacement.

“…The same occurred with regard to ETCO 2 , as both groups maintained the parameter within the normal range for the species, although inhalational anesthetics may promote an increase in ETCO 2 values as a result of respiratory depression [35]. SpO 2 and ETCO 2 were not obtained at baseline time (M0) due to the di culty of evaluation through the equipment used, as the animals were conscious.…”

Background Amantadine is effective in the treatment of nervous system disorders as it blocks NMDA receptors, showing potential as an analgesic agent by inhibiting central sensitization. The aim was to evaluate the preemptive effect of amantadine on postoperative analgesia in cats undergoing ovariohysterectomy and its influence on the physiological parameters of the treated animals. For this purpose, 20 healthy domestic cats, were divided into two sample groups with 10 animals each and referred for ovariohysterectomy. In the control group (CG) the cats orally received placebo capsules 30 minutes before the standard anesthetic protocol. In the amantadine group (AG) the animals orally received 5mg/kg of amantadine 30 minutes before the standard anesthetic protocol. The presence of adverse effects after administration of the capsule was evaluated. An intraoperative evaluation was performed at different times during the surgical procedure, assessing the following parameters: heart and respiratory rates, oxyhemoglobin saturation, end-tidal carbon dioxide, end-tidal isoflurane concentration, esophageal temperature, and systolic blood pressure. Post-surgical pain was assessed using the Visual Analog Scale and the Multidimensional Scale for the evaluation of post-operative pain in cats of the Universidade Estadual Paulista (UNESP) – Botucatu.Results Amantadine did not influence the evaluated physiological parameters. The group that received amantadine had lower pain scores on both scales when compared to the control group and required fewer analgesic rescues.Conclusions It was concluded that the preemptive, oral administration of amantadine, at a dose of 5mg/kg, was effective in controlling postoperative pain in cats undergoing ovariohysterectomy, without causing adverse effects or alterations in the physiological patterns of the treated animals.

“…O ETCO 2 é infl uenciado pela f, e esta não diferiu de M0 em nenhum momento, mantendo assim a ETCO 2 estável durante todo o estudo. Levando em consideração o protocolo utilizado neste estudo, é conhecido que o isofl uorano promove depressão respiratória dosedependente (GALLOWAY et al, 2003). No entanto, como a vaporização foi mantida em 1,3V%, não foram observadas diferenças entre tempos ou entre grupos durante o procedimento, sendo os valores aceitáveis para a espécie.…”
