    Abstract: Male and female sterilization have been established as the main technique to reduce the huge number of mongrel dogs. However, there are several barriers regarding to the choice of the best anesthetic protocol, in terms of efficacy, security and cost reduction. The aim of this study was to evaluate the analgesic, cardiorespiratory and hemogasometric effects of epidural anesthesia with a large volume of lidocaine in combination with morphine in female dogs submitted to ovariosalpingohisterectomy (OSH), with or without oxygen supplementation. Twelve adult female dogs were used, with average weight of 11.5±3.7kg and age of 1 to 4 years. The animals received acepromazine (0.1mg kg-1) and meperidine (5mg kg-1) as premedication, administered by the intramuscular route. Fifteen minutes later, thiopental (10mg kg-1) was administered by intravenous route, followed by endotracheal intubation. The animals were allocated into two groups: GCO (group with oxygen, n=06), where the animals received 100% oxygen supplementation and GSO (group without oxygen supplementation, n=6), mantained with endotracheal intubation, but without oxygen supplementation. After intubation, epidural with morphine (0,1mg kg-1), adjusted to 1mL 3kg-1 in lidocaine 2% without epinepherine was administered. Immediately after epidural administration, the animals were positioned in dorsal recumbency, with the head in the same level of the body. In both groups, surgery was performed without the need of additional analgesia and without signs of pain. Mean arterial pressure (MAP) was lower in GSO in all moments compared to baseline values. In GCO, MAP was lower after premedication and epidural anesthesia. Respiratory rate was lower from M1 to M6 in GSO. The SaO2 and PaO2 were higher in GCO when compared to GSO. The pH was lower in GCO after 15 minutes after premedication, until 40 minutes after the epidural administration, compared to GSO. It was concluded that the epidural administration using morphine and lidocaine in the dosage and volume proposed are effective to OSH procedure in dogs. The lack of oxygen supplementation promoted minimal cardiovascular and hemogasometric alterations, which is feasible in sterilizations campaigns where there is no possibility of oxygen supplementation of the animals.

    Abstract: RESUMO: A adequada monitoração do índice cardíaco (IC) em pacientes críticos requer métodos acurados e minimamente invasivos. O objetivo deste estudo foi comparar o IC obtido por termodiluição ou ecocardiografia em cães sob alterações hemodinâmicas. Utilizaram-se nove cães pesando 19,6±1,3kg, os quais foram anestesiados com isofluoranoa1,4V% (Basal) e submetidos à ventilação mecânica (VM) e estados hipodinâmico (Hipo) com isofluoranoa3,5V% e hiperdinâmico (Hiper), com dobutaminaa5µgkg-1min-1. O IC foi obtido por termodiluição (TD) e pelos métodos ecocardiográficos de Simpson modificado, e pela velocidade em tempo integral (VTI) nas valvas aórtica (VTI-A) e pulmonar (VTI-P). Realizou-se a análise de correlação de Pearson e de concordância de Bland-Altman. O IC (Lm-2min-1) nas fases Basal, VM, Hipo e Hiper foi de 4,3±1, 3,6±0,7, 2,9±0,66 e 6,1±2 para TD; 2,8 ±0,7, 2,4±0,3, 1,7±0,7 e 4,4±1,2 para Simpson; 3,4±0,9, 3,1 ±0,7, 2,6±3,4, 6,1±1,8 para VTI-A e 3,6±0,8, 3,6±0,8, 2,7±0,6 e 6,2±1,5 para VTI-P. O método de Simpson foi menor que a TD em todas as fases, mas com correlação significativa nos estados Hipo (r=0,89) e Hiper (r=0,76) e percentagem de erro de 26% no Hipo em relação à TD, identificando os diferentes estados hemodinâmicos. Nos demais, não houve concordância ou correlação com a TD. Conclui-se que nenhum dos métodos testados apresentou concordância aceitável com a termodiluição nos diferentes estados hemodinâmicos.

    Abstract: The objective of this study was to compare the effects of two local anesthetics used on auriculopalpebral block on eyelid akinesia, tear production, intraocular pressure (IOP) and tear break-up time (TBUT) in conscious dogs. A blind, randomized, prospective study was conducted to determine the effects of auriculopalpebral block using ropivacaine 0.75% and bupivacaine 0.5% in 12 healthy non-brachycephalic dogs (24 eyes). Threat response and eyelid reflex tests, Schirmer tear test (STT), IOP and tear break-up time were conducted before blockage and at 30, 60, 120, 240 and 360 minutes after application. A difference was observed between the values found at 30, 60, 120 and 240 minutes compared to baseline for threat response and eyelid reflex tests in the two groups evaluated, proving eyelid akinesia after blockages. No difference was found for STT, IOP and TBUT between baseline values and post-anesthesia times or between groups. It was possible to conclude that ropivacaine and bupivacaine on auriculopalpebral block in conscious dogs promoted eyelid akinesia for at least 240 minutes, not altering ocular physiological parameters of tear production, intraocular pressure, and tear break-up time after blockages.

    Abstract: The aim of this study was to estimate the population size of dogs and cats domiciled and semi-domiciled in the urban area of the city of Jataí, Goiás, Brazil, highlighting some features of these animals, like sex and mobility. An observational descriptive sample survey was used and households were randomly selected for the study. In total, 385 households were visited, with 1215 residents. Of the households, 63.63% had at least one dog and 11.17% had at least one cat. The dog: human ratio was 1:2.92 and cat: human ratio was 1:11.79. In relation to the canine population (416), 37.02% were male (5.29% neutered and 31.73% non-neutered) and 62.98% were female (9.37% neutered and 53.60% non-neutered). The feline population was 103 animals, 39.80% were male (14.60% neutered and 31.47% non- neutered) and 46.60% were female (18.86% neutered and 37.08% non-neutered). In relation to street access, 32.93% of dogs and 84.46% of cats were semi-domiciliary. The estimated population of canines and felines domiciled and semi-domiciled in the urban region of the city of Jataí, in 2018, was 3.605 and 8.323, respectively. These results highlight the need to implement strategies for population control associated with actions to raise awareness about responsible animal custody.

    Abstract: Seeking to evaluate the cardiovascular and analgesic effects of two epidural protocols in cats undergoing OH, 16 female adult mixed-breed cats were induced to general anesthesia, and then epidural was achieved with 0,26mL kg-1 of isolated ropivacaine (GR) (0,75%) or associated with 0,1mg kg-1 morphine (GRM). ETCO2, RR, HR, SAP, T° and muscular relaxation were evaluated in baseline, 30 minutes after epidural; after skin incision, ovarian pedicles and uterine cervix ligation; end of laparohraphy; and end of surgery. They received fentanyl if SAP, HR or f, rise in 20% of baseline. At the end of OH, a multidimensional pain scale for cats was used during 12 hours, and rescued with morphine 0,2mg kg-1, when the scale score was ≥8 points. There were no differences in ETCO2, RR, T°C and muscular relaxation. SAP increased in both groups during the ovarian pedicle and cervix clamping. In 100% of the animals in GR and 87.5% of the GRM, it was necessary fentanyl during surgery. In 100% of GR animals was required analgesic rescue with morphine at 2 and 4 hours of postoperative evaluation, compared with 50% and 37,5% in GRM, where after the analgesic rescue, in the next hours, the sum of points was similar between groups. It was concluded that epidural administration of morphine and ropivacaine in cats submitted to OH, reduces post operatory analgesic requirements to 56,2% during the first four hours, and promote adequate analgesia for 12 hours in cats submitted to OH, when compared to ropivacaine alone

    Abstract: O objetivo do trabalho é realizar uma revisão de literatura dos principais bloqueios anestésicos utilizados em cirurgias oculares de cães e gatos, mostrando quando devem ser indicados, as formas de aplicação, as principais vantagens e as complicações que mais ocorrem neste tipo de anestesia. Realizou-se uma revisão narrativa, utilizando artigos científicos, monografias, teses e dissertações publicadas e disponíveis nas bases de dados online: Periódico Capes (Coordenação de Aperfeiçoamento de Pessoal de Nível Superior), SciELO (Scientific Electronic Library Online) e Google Acadêmico, além de livros específicos do tema. Os principais bloqueios anestésicos utilizados para cirurgia ocular são o retrobulbar, o peribulbar e os bloqueios palpebrais, além da anestesia da superfície ocular. O uso de bloqueios oftálmicos, quando realizados de maneira adequada, representa um complemento eficaz à anestesia geral, uma vez que diminuem os efeitos sistêmicos de fármacos, diminuem a necessidade de anestésicos inalatórios e/ou intravenosos, além de proporcionarem analgesia pós-operatória. Em virtude da maior proximidade e cuidado dos animais por seus tutores, nos últimos anos têm aumentado o número de procedimentos oftálmicos na clínica de cães e gatos. Assim, é importante que o anestesista tenha conhecimento sobre as particularidades da anestesia nesses pacientes, bem como sobre os principais bloqueios usados na região craniana e qual a técnica e o anestésico local mais adequado para cada tipo de procedimento.

    Abstract: Background: Hemogasometric analysis is used in the interpretation of acid-base balance (ABB) and to access pulmonary ventilation. Already mixed venous oxygen saturation obtained at pulmonary artery correlates with tissue oxygenation. However, both samples can be difficult to access because of the difficulties in arterial and pulmonary catheterization. The aim of this study was to evaluate the feasibility of replacing the arterial and mixed venous bloods, the end tidal pressure of carbon dioxide (EtCO2) and central venous blood in the analysis of pulmonary ventilation, tissue oxygenation and ABB in dogs under different hemodynamic states.Material, Methods & Results: Nine dogs were used with an average weight of 19.6 ± 1.3 kg, anesthetized with isoflurane at 1.4 V% diluted on oxygen 60% (Baseline), and subsequently undergoing mechanical ventilation (MV) and the hypodinamic state (Hypo) with isoflurane at 3.5V% and mean arterial pressure (MAP) lower than 50 mmHg and hyperdynamic state (Hyper) by dobutamine infusion at 5 μg/kg/min and with MAP 30% higher than baseline. For each time allowed a 15 min of stabilization by each hemodynamic status. Simultaneously were collected samples of 0.6 mL of arterial blood by metatarsal artery, mixed and central venous blood by pulmonary artery and right atrium for hemogasometric analysis. To access lung function we correlated and compared the EtCO2 values obtained by gas analyzer with expired carbon dioxide pressure in the arterial blood (PaCO2), mixed venous blood (PmvCO2) and central venous blood (PcvCO2). For the interpretation of tissue oxygenation we correlated and compared the values of mixed (SmvO2) and central (ScvO2) venous oxygen saturation. For the acid-base balance we used the correlation of potencial hydrogen (pH); carbon dioxide pressure (PCO2); bicarbonate ion (HCO3-); base excess (BE); anion GAP (AG); sodium ions (Na+), chlorine ions (Cl-), potassium ions (K+) and ionized calcium (iCa) of arterial (a) mixed venous (mv) and central venous (CV) bloods. Statistical analysis was performed using ANOVA-RM followed by Dunnet test for differences between times and Tukey’s test for differences among the samples (P ≤ 0.05). Pearson correlation analysis was performed using linear regression and for comparison methods we used the Bland-Altman analysis The EtCO2 values correlated (r = 0.87) and were according to Bland-Altman analysis with PaCO2 values (mean difference of -1.6 ± 2,9 mmHg for PaCO2. There were no differences (P ≤ 0.05) from SmvO2 and ScvO2. ScvO2 correlated (r = 0.91) with SmvO2 at different hemodynamic states and with a mean difference of -0.4 ± 2.5%. Both venous bloods were correlated with the analysis of arterial blood acid-base balance and electrolytes in different hemodynamic states. However, the ionized calcium levels were 40% lower in arterial blood.Discussion: EtCO2 measurement depends of monitor technology and proper pulmonar ventilation and perfusion. In this study the limiting factor in replacing the PaCO2 hair EtCO2 was spontaneous ventilation because in this state pulmonary ventilation is compromissed. With the use of MV was possible get up similar results in the pulmonar function analysis using the EtCO2 and PaCO2. The use of central venous blood instead mixed venous blood at oxygen saturation analysis provided adequate estimate this parameter. This being easier and less invasive technique. ABB was possible with all samples with own reference values for venous and arterial samples. This is an interesting result for critical patients where the arterial sample is difficult. In electrolytes the sample was indifferent except for calcium because pH interfere in this values. It was conclude that the values of EtCO2 and central venous blood are correlated and can replace arterial and mixed venous bloods in the analysis of lung function, tissue oxygenation and acid base balance.
