“…Para Oliveira (2005), até mesmo pequenos valores de PIA (10mmHg) originam diminuição no débito cardíaco, e, quando estão acima de 22mmHg, a pré-carga encontra-se diminuída em até 80% dos pacientes humanos normovolêmicos. Entretanto, mesmo com a considerável diminuição nas pressões arteriais durante a execução das técnicas de NOTES, esses parâmetros ainda estavam dentro dos limites fisiológicos defendidos por Conceição et al (2005) e, assim, não comprometem a exequibilidade segura dos procedimentos.…”

RESUMOA cirurgia endoscópica por orifícios naturais (NOTES) é um novo conceito de abordagem videocirúrgica, que surge como alternativa à cirurgia convencional, eliminando incisões abdominais e as possíveis complicações relacionadas a ela. A proposta deste artigo foi comparar técnicas de ovariossalpingohisterectomia (OSH) em cadelas, buscando determinar o procedimento que oferece menores alterações hemodinâmicas e menos estímulos dolorosos trans e pós-operatório. Para tanto, foram utilizadas 21 cadelas alocadas em três grupos. No primeiro, os pacientes foram submetidos à OSH por celiotomia (GC), no segundo por meio da técnica de NOTES híbrida (GNH) e no terceiro (GNT), utilizando-se a técnica de NOTES total. O tempo cirúrgico do GNH foi significativamente maior que nos demais grupos. Em ambos os grupos de cirurgia NOTES, verificou-se diminuição das pressões arteriais médias e diastólicas no transoperatório. Apenas o grupo GNH desenvolveu acidose severa no transoperatório. Levando-se em consideração as avaliações da dor, apenas o grupo convencional necessitou de analgesia resgate transcirúrgica. No pós-operatório, observou-se que os cães do GC apresentaram índices mais elevados na escala visual analógica e na escala de Melbourne que os animais dos demais grupos, sendo necessária analgesia resgate em 100% deles. Em contraste, no GNT nenhum dos cães requereram complementação analgésica pós-operatória. Conclui-se que a técnica de OSH por NOTES total apresenta parâmetros cardiorrespiratórios e hemogasométricos semelhantes à técnica convencional e mais estáveis que a técnica de NOTES híbrida, bem como resulta em menor dor trans e pós-operatória que a técnica convencional.Palavras-chave: cão, cirurgia endoluminal, cirurgia sem incisão, videocirurgia ABSTRACT

“…It is known that drugs administered for anesthesia procedures can interfere with an animal's physiological parameters. Isoflurane is an inhaled halogenated anesthetic that has minimal cardiovascular effects (Conceição et al 2005). This drug does not sensitize the myocardium to catecholamine and induces peripheral vascular resistance and blood pressure by decreasing β-adrenergic stimuli (Paget et al 1991).…”

RESUMO.-[Avaliação de parâmetros fisiológicos de cães submetidos ao mapeamento linfático uterino usando o corante azul patente V para a detecção de anafilaxia.] O mapeamento linfático tem sido realizado em humanos e cães. Embora inúmeros casos de anafilaxia já tenham sido relatados em humanos, não existem tais relatos em cães. O objetivo deste estudo foi identificar a ocorrência de reações adversas ao corante azul patente V em cadelas submetidas ao mapeamento linfático uterino, usando avaliações cardiovasculares e hematológicas. O experimento foi realizado em 14 cadelas mestiças, divididas igualmente em dois grupos (PBV-mapeamento linfático uterino e OEH; Controle -apenas OEH). Os animais foram submetidos a exames hematológicos e bioquímicos séricos no pré e pós-operató-rio (7 dias). O protocolo anestésico foi: sedação (morfina e acepromazina), indução (propofol), manutenção (isoflurano), analgesia trans-operatória (fentanil Lymphatic mapping has been performed in humans and dogs. Although several cases of anaphylaxis have been reported in humans, there are no such reports in dogs. The objective of this study was to identify the occurrence of adverse reactions to patent blue V dye in bitches undergoing uterine lymphatic mapping procedures using cardiovascular and hematological evaluations. The experiment was performed in 14 mongrel bitches without any reproductive disease, randomly assigned into two equal groups (PBV-uterine lynphatic mapping and OHE; Control -OHE only). The animals were submitted to pre-and postoperative hematological and serum biochemistry exams (7 days). The anesthetic protocol was: sedation (morphine and acepromazine), induction (propofol), maintenance (isoflurane), transoperative analgesia (fentanyl). Systolic blood pressure was monitored throughout the procedure and arterial blood gas analysis was performed immediate pre and postoperatively. For lymphatic mapping was injected patent blue V in the uterine wall, 10 minutes before OEH. Comparisons between the pre-and postoperative parameters within the same animal were performed using the Wilcoxon-Mann-Whitney test. To compare the values between control and PBV group was obtaining the difference between the pre and post of each group, subjected to the Mann-Whitney test (significance of 5%). Differences were observed (P<0.05) between the pre-and postoperative evaluations in the PBV (total protein and the albumin serum), in both groups (arterial partial pressure of oxygen) and in the Control (arterial oxygen saturation). There were no signs of adverse reactions to the patent blue V dye in the healthy bitches submitted to lymphatic uterine mapping.INDEX TERMS: Uterine lymphatic mapping, patent blue V dye, anaphylaxis, hypersensitivity, bitches, vital dye.

The aim of this study was to identify the clinical, epidemiologic and laboratorial aspects of dogs with obesity and its possible correlation with other diseases. A total of 30 dogs were studied. Of these, 15 were obese and 15 were not. On the Control Group, there was a total of 10 females (5 neutered and 5 whole) and 5 males (all 5 neutered). On the Obese Group, 11 females (7 neutered and 4 whole) and 4 males (all 4 neutered). The tutors received a form with 12 questions about food management and physical activity, as well as pharmacological and family history. In addition, venous blood samples were collected in animals from both the Control Group and the Obese Group for a Complete Blood Count and dosage of biochemical levels (Alanine Aminotransferase, Alkaline Phosphatase, Albumin, Total Proteins, Urea, Creatinine). Measurements from the abdominal perimeter were taken and using the data the body fat percentage was calculated; an Electrocardiographic evaluation (ECG) was also made, along with the measurement of the systolic, diastolic and medium blood pressure (SBP, DBP and MAP, respectively) and heart rate (HR). The numeric data was submitted under the Analysis of Variance (ANOVA), followed by the Tukey’s Test (p<0,05), while the data regarding risk factors was analyzed on a descriptive manner. In both groups, mixed-breed dogs had a significant predominance, about 9 (60%) on the CG and 7 (46,66%) in the Obese Group. Concerning food management, 12 (80%) of the subjects of the Control Group were fed at will and 3 (20%) once a day; the numbers on the use of only pet food, pet food coupled with homemade food, and only homemade food were, respectively, 10 (66,6%), 4 (26,6%) and 1 (6,8%). Also, 11 (73,3%) had frequent physical activities, while the other 4 (26,7%) only occasionally. Additionally, 12 (80%) stayed at the backyard, while 3 (20%) lived in an apartment. There was not any relevant data relating to pharmacological and family history and, according to tutors’ opinions, their dogs were within the ideal weight. On the Obese Group, 8 (53,5%) were fed at will, 5 (33,3%) were fed on a strict and controlled manner, and 2 (13,3%) one time a day, while 9 (60%) of them were given both pet food and homemade food, 5 (33,3%) received only pet food and 1 (6,7%) received pet food sachets and fruit. In this group, 9 (60%) were out, 15 did not practice any type of physical activity, while 3 (20%) practiced frequently and the other 3 (20%) walked occasionally. There were 5 patients (33,3%) with a history of corticosteroid use, and 7 (46,7%) had a family history of obesity. Regarding tutors’ opinions on their pet’s weight, on whether they thought their pet was too thin, on ideal weight, overweight or obese, the data showed, respectively, 2 (13,3%), 4 (26,7%), 8 (53,3%) and 1 (6,7%). The percentage of fat on the Control Group for males and females was, respectively, 18,7 ± 2,2; 22 ± 3, while the abdominal circumference was of 63 ± 20 cm. On subjects from the Obese Group, the values were 40,4 ± 5; 45 ± 4,7 and 65 ± 16,8 cm, respectively. On laboratory exams, the Complete Blood Control did not show any inconsistencies with the normal range and the ALB and FAL were elevated on the Obese Group. The ECG did not show any notable changes. Both groups showed a slight increase in PAS (Control Group = 141 ± 27,72 mmHg; Obese Group = 142 ± 17,23 mmHg), and on the obese animals a raise in PAD (84 ± 22 mmHg) was also recorded. Obesity is a chronical disease that brings a series of bad consequences to the animal well-being, especially the appearance of systemic diseases; the main risk factor for its appearance is incorrect food management and low or nonphysical activity. The main way to prevent the disease is by the correct management of both factors.
