ABSTRACT This study aimed to evaluate the viability of using a non-invasive digital monitor to monitor heart rate (HR) and motility during the embryonic development of Pantanal alligator (Caiman yacare) using Egg Buddy ® , at different incubation temperatures. The collection of the eggs followed the Ranching system and egg identification, transportation, and incubation were performed with the required care; all eggs were incubated with 90% humidity at 29°C for the first 45 days. Thereafter, the incubation temperature was either maintained at 29°C, increased to 33°C or maintained at 29°C and embryos simultaneously treated with 4-aminopyridine on days 46, 47, 48, and 49 (29°C-4AP). Embryo movement was measured with a digital non-invasive monitor on days 30, 35, 42, 49, 56, and 60, at which point embryos were sacrificed. In the statistical analysis no differences were observed between the groups for the temperature (33°C and 29°C); for motility, a difference was observed at day 49 for the 29°C-4AP group. This revealed that the non-invasive evaluation method can be used to verify embryonic motility and HR effectively in Caiman yacare embryos.

RESUMO Avaliou-se a recuperação anestésica e a analgesia residual da infusão contínua (IC) de fentanil (F), lidocaína (L), cetamina (K) e fentanil-lidocaína-cetamina (FLK), associados à anestesia total intravenosa com o propofol, em cadelas submetidas à ovariossalpingo-histerectomia. Foram utilizados 32 animais pré-medicados com acepromazina, distribuídos em quatro grupos de acordo com o tratamento analgésico: F: bolus de 0,0036mg/kg de fentanil e IC de 0,0036mg mg/kg/h; L: bolus de 3mg/kg de lidocaína e IC de 3mg/kg/h; K: bolus de 0,6mg/kg de cetamina e IC de 0,6mg/kg/h; e FLK: bolus e IC dos três fármacos nas doses supracitadas. Após o bolus do tratamento analgésico, foi realizada a indução e o início da IC do tratamento analgésico e do propofol. Para avaliação da recuperação anestésica, foram considerados os tempos de extubação, decúbito esternal, posição quadrupedal e os efeitos adversos. A avaliação da analgesia foi realizada por meio da escala visual analógica e modificada de Glasgow, durante seis horas. Os efeitos adversos observados foram vômito, sialorreia e tremor muscular. Receberam analgesia de resgate 100% dos animais do grupo F, 87,5% do K, 50% do L e 12,5% do FLK. O FLK demonstrou maior analgesia, e a recuperação anestésica foi semelhante em todos os grupos.

ABSTRACT The anesthetic recovery and residual analgesia of continuous rate infusion (CRI) of fentanyl (F), lidocaine (L), ketamine (K) and fentanyl-lidocaine-ketamine (FLK) associated with total intravenous anesthesia with propofol in bitches submitted to ovariohysterectomy were evaluated. 32 animals were used, pre-medicated with acepromazine and distributed into four groups according to analgesic treatment: F loading dose (LD) of 0.0036mg/kg fentanyl, and CRI of 0.0036mg/kg/h, L: LD of 3mg/kg lidocaine, and CRI of 3mg/kg/h; K: LD of 0.6mg/kg ketamine, and CRI of 0.6mg/kg/h and FLK: LD and CRI of the three drugs in the above mentioned doses. After the LD of analgesic treatment, the induction was performed and the CRI of the analgesic treatment and propofol started. To evaluate the anesthetic recovery, the time of extubation, sternal decubitus, quadrupedal position and adverse effects were considered. The analgesia evaluation was performed using the visual scale and modified Glasgow for six hours. The adverse effects observed were vomiting, sialorrhea and muscle tremor. 100% of the animals in group F, 87.5% of K, 50% of L and 12.5% of FLK received rescue analgesia. FLK demonstrated greater analgesia, and anesthesia recovery was similar in all groups.

A síndrome de Horner é uma disfunção do sistema nervoso autônomo simpático, decorrente de qualquer injúria a essa via de transmissão nervosa. Este artigo descreve um caso da síndrome após cirurgia para a transposição da artéria carótida comum. Os sinais clínicos observados foram sudorese de face e pescoço, com hipertermia localizada, paralisia facial e ptose palpebral. A maioria dos sinais foi transitória e se manifestou por até duas horas após a remoção do cateter percutâneo, introduzido na artéria transposta. Como essa manifestação foi recorrente nas venóclises subsequentes e a ptose palpebral perdurou por 10 meses, desde a primeira punção arterial, ressalta-se a importância e o critério quando da necessidade de manipulação cirúrgica dessa região anatômica.

Horner's syndrome (HS) is a sympathetic dysfunction caused by injuries to the sympathetic pathway. A clinical case of HS following common carotid artery transposition and catheterization in a horse is described. The animal presented head and neck sweating with focal skin temperature elevation, facial paralysis and ptosis. Most clinical signs were transient and persisted for two hours following percutaneous catheter removal. Recurrence of clinical signs was observed at subsequent catheterizations. Ptosis endured for 10 months as a consequence of the first catheter placement which demonstrates the importance of careful manipulation of the anatomical structures of the neck when performing any surgical manipulation in this area.
