Resumo

Laparoscopy procedures are useful tools to perform some assisted reproductive biotechnologies in ewes, it requi-res general anesthesia and manoeuvres that might result in alteration of the cardiopulmonary function. For this reason, this study aimed to investigate the effects of oxygen supplementation as a therapeutic measure to mitigate these alterations in ewes submitted to laparoscopic ovum pick-up (LOPU) under total intravenous anesthesia (TIVA). Twenty-four healthy adult ewes were submitted to two LOPUs with a 21 days interval, under ketamine-midazolam anesthesia, and receiving each of the two experimental in random order, oxygen treatment (OT) 50 mL/kg/min of oxygen via endotracheal tube and control treatment (CT) not receive any inhalation treatment. Heart rate (HR), respiratory rate (fR), peripheral oxygen saturation (SpO2), mean arterial pressure (MAP), rectal temperature (RT), end-tidal CO2 concentration (EtCO2) and recovery anesthesia time were evaluated during LOPU, arterial blood gases and electrolytes were evaluated after induction of anesthesia and at the end of the LOPU. Variables were compared between groups and moments using ANOVA. MAP, SpO2, PaO2, SaO2 and pH were higher in OT, while EtCO2, PaCO2, temperature loss and recovery time were lower. These results allow to conclude that oxy-gen supplementation in ewes submitted to LOPU under TIVA provides benefits in order to mitigate physiological alterations.(AU)


Os procedimentos de laparoscopia são ferramentas úteis para realizar algumas biotecnologias de reprodução assistida em ovelhas, requer anestesia geral e manobras que podem resultar em alteração da função cardiopulmonar. Por esse motivo, este estudo teve como objetivo investigar os efeitos da suplementação de oxigênio como medida terapêutica para atenuar as alterações em ovelhas submetidas à Aspiração Folicular guiada por Laparoscopia (LOPU) sob anestesia venosa total (TIVA). Vinte e quatro ovelhas adultas saudáveis foram submetidas a duas LOPUs com intervalo de 21 dias, sob anestesia com cetamina-midazolam, recebendo cada um dos dois experimentos em ordem aleatória, tratamento com oxigênio (OT) 50 mL/kg/min de oxigênio via tubo endotraqueal e tratamento de controle (CT) não recebem nenhum tratamento por inalação. Frequência cardíaca (FC), frequência respiratória (FR), saturação periférica de oxigênio (SpO2), pressão arterial média (PAM), temperatura retal (TR), concentração expirada de CO2 (EtCO2) e tempo de recuperação da anestesia foram avaliados durante LOPU, arterial gasometria e eletrólitos foram avaliados após a indução da anestesia e ao final da COL. As variáveis foram comparadas entre grupos e momentos por meio de ANOVA. PAM, SpO2, PaO2, SaO2 e pH foram maiores no TO, enquanto EtCO2, PaCO2, perda de temperatura e tempo de recuperação foram menores. Estes resultados permitem concluir que a suplementação de oxigênio em ovelhas submetidas a LOPU sob TIVA proporciona benefícios no sentido de atenuar as alterações fisiológicas.(AU)

The aim of this study was to investigate uterine involution using ultrasonography techniques during postpartum. Postpartum ultrasonography evaluation (B-mode, color Doppler and Acoustic Radiation Force Impulse elastography) of the uterus was performed by transabdominal approach at immediate after birth and sequentially every 48 hours, during 30 days. The uterine echotexture did not present significant variations (P >0.05) being homogeneous in most evaluations; echogenicity of the uterus increased along the evaluation period (P =0.0452). Progressive and remarkable decrease of the total uterine diameter (UD) were observed (P <0.0001), especially during the first days postpartum. The thickness of uterine wall gradually decreased, as well the endometrial, myometrium and lumen diameters (P <0.0001). Uterine blood flow was assessed by Doppler and decreased during postpartum period, being significantly lower (P=0.0225) on the 30th day of postpartum. Uterine parenchyma presented as homogeneous dark areas (not deformable) on qualitative ultrasound elastography and the means shear velocity values of the uterine wall on quantitative elastography did not differ. This is the first study that evaluate the stiffness of uterine wall in healthy ewes, providing baseline data about quantitative and qualitative stiffness of the normal uterus, and it may be a useful tool for early diagnosis of uterine alterations during the postpartum period, using the reference parameter established for the assessment of uterine integrity during postpartum period.(AU)

The objective was to evaluate the blood flow of the uterine artery (UA) and umbilical artery (UMB) in the physiological pregnancy of goats by means of Doppler throughout the gestational period. Twenty-five Saanen goats weighing 55 ± 10 kg and aged between 2 and 5 were evaluated weekly, from the 21st until the 143rd day of gestation, and daily from that period until parturition. Values for peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance (RI) and pulsatility (PI) indices of the uterine and umbilical arteries were determined. The values obtained were correlated with gestational age by Spearman's test, tested for adjustment to regression models and compared with the number of fetuses by ANOVA. The umbilical cord was first visualized at 28 days. Of the variables evaluated, RIUMB and PIUMB correlated with gestational age (p<0.001; and 0.046; respectively) and RIUMB had a low negative correlation with the number of fetuses per pregnancy (p = 0.003; r- Spearman = - 0.218). PSVUMB and EDVUMB values did not correlate with gestational age (p=0.737 and 0.768, respectively), but there was a decrease in the mean values throughout pregnancy (PSVUMB= 0.07; 0.31 and EDVUMB= 0.01; 0.06) as well as the change in the flow pattern of the spectral trace. The mean values of the uterine artery dopplervelocimetric variables PSVUT, EDVUT, PIUT and RIUT did not correlate with gestational age (p= 0.324; 0.372, 0.143; 0.13; respectively). It is expected that the results obtained will contribute to a broader understanding of the hemodynamic changes resulting from pregnancy in goats.(AU)

The aim of this study was to evaluate the blood flow of the uterine artery, fetal aorta and umbilical artery in the physiological pregnancy of sheep by means of pulsed Doppler throughout the gestational period. Thirty Santa Inês ewes weighing between 45.4±4.3 kg and aged 2 to 5 years were selected. The evaluations were carried out weekly from the 3rd to the 21st gestational week. Peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index (RI) were obtained. Analysis of variance was performed, and the minimum significant comparison of means was obtained by the BH test with adjusted P<0.05. The results were expressed as mean ± standard error. For the fetal aorta, there was an increase in the EDV values and a decrease in the PSV and RI throughout pregnancy. For the uterine artery, PSV and EDV did not present significant variation, whereas the RI showed a reduction in the last week. Increased EDV values were found for the umbilical artery throughout pregnancy. For the PSV there was no significant difference, as the RI was reduced at the end of pregnancy. The results obtained are expected to contribute to a more complete understanding of the hemodynamic changes resulting from pregnancy.(AU)

Puerpério é o período após a finalização do parto e acontece em escala logarítmica decrescente, especialmente durante a primeira semana após o parto, quando o útero passa por marcado remodelamento durante sua involução. No entanto, não estão totalmente elucidados os mecanismos hormonais, celulares e moleculares que regulam esse processo. Considerando a necessidade de estabelecer métodos diagnósticos precoces para a avaliação das mudanças no puerpério em ovelhas e a escassez no número de estudos sobre involução uterina, o monitoramento desse período é essencial para evitar declínio na eficiência reprodutiva, sendo que o intervalo de partos está diretamente relacionado à velocidade da involução uterina e ao retorno à atividade reprodutiva das fêmeas. Para isso, o entendimento do processo de recuperação do trato reprodutivo no pós-parto dessa espécie é de grande importância para o sucesso do sistema de produção em ovinos. Neste trabalho, revisamos o período puerperal, os mecanismos subjacentes à reprodução normal dos ovinos e a ultrassonografia para avaliar esse período na ovelha como modelo experimental ou para aplicação em Medicina Veterinária.(AU)

However, hormonal, cellular, and molecular mechanisms that regulate this process are not fully understood. Considering the need to establish early diagnostic methods to evaluate changes during sheeps puerperium and the scarce number of studies on uterine involution, monitoring this period is essential to avoid declining in reproductive efficiency, as calving interval is directly related to the speed of uterine involution and the return to female reproductive activity. Therefore, understanding the postpartum reproductive tract recovery process of this species is of great importance for the success of sheep production systems. We review the puerperal period, the mechanisms underlying the normal reproduction of sheep and ultrasonography to evaluate this period as an experimental model or for application in Veterinary Medicine.(AU)

A parturição prematura é fator relevante para a morbidade e mortalidade perinatal em humanos e a determinação da maturidade fetal é de extrema importância, principalmente em gestações de alto risco relacionadas à prematuridade. Em virtude dos estágios de desenvolvimento dos órgãos, em relação ao nascimento, serem semelhantes em ovinos e humanos, a espécie ovina tem sido utilizada como modelo experimental para estudos sobre a maturidade tecidual em conceptos, bem como para emprego de terapias pré-natais (corticosteróides) e suas respostas neste processo. Uma das técnicas que podem ser utilizadas para avaliação do desenvolvimento dos tecidos materno-fetais ovinos é a ultrassonografia, método seguro e não invasivo que fornece informações importantes quanto a maturidade fetal e aspectos maternos que podem contribuir para a determinação do momento do parto e consequente redução da morbidade e mortalidade neonatal em ovinos. Deste modo, esta revisão objetiva descrever aspectos fisiológicos maternos e fetais das últimas semanas gestacionais até o momento do parto em ovinos, assim como mostrar as diferentes técnicas ultrassonográficas utilizadas para a avaliação destas características, afim de auxiliar na identificação de um parto prematuro e/ou gestações de alto risco.(AU)


Premature birth is a relevant factor for perinatal morbidity and mortality in humans and the determination of fetal maturity is extremely important, especially in high-risk pregnancies related to prematurity. Because the stages of organ development in relation to birth are similar in sheep and humans, the ovine species has been used as an experimental model for studies on fetal tissue maturity, as well as for the use of prenatal therapies (corticosteroids) and its action during this process. One technique that can be used to evaluate the development of ovine maternal and fetal tissues is the ultrasound, wich is a safe and noninvasive method that provides important information about the moment of delivery, aids the determination of fetal maturity, the diagnosis of possible premature birth and consequently contributes to the reduction of neonatal morbidity and mortality. This review aims to describe the physiological aspects of the last gestational weeks until delivery, as well as to show the different ultrasound techniques used to assess fetal maturity in order to assist the identification of premature delivery and/or high risk pregnancies.(AU)

Background: Ovariectomy(OVE) and ovariohysterectomy (OVH) are the most performed surgical procedures in Veterinary Medicine. In videosurgery, both in stray animals at sterilization campaigns and in the increasing demand of tutors to perform the technique. Laparoscopy results in reduced tissue damage, due to minimal organ manipulation and surgical access hemostasis can be performed by several methods, such as electro-coagulation, clips, and intra and extracorporeal ligatures. A pre-tied ligature system, or endoloop, is a haemostatic technique comprised of a slipknot and knot pusher, which is inserted into the abdominal cavity through one of the laparoscopic ports. The aim of this study was to describe a novel OVE technique in cats, in which haemostasis was performed using miniloop, aimed at reducing the number of ports needed for knot tying.Material, Methods & Results: Ten healthy not spayed female cats, aged 6 months to 5 years, were selected for this study. They were submitted to an OVE using miniloop as haemostasis method. Access to the peritoneal cavity was through two 5 mm ports on the midline of the ventral abdomen, 5 cm apart, with one immediately caudal to the umbilical scar and the other in between the last pair of teats. The first trocar was inserted at the caudal incision using the Hasson technique and a 5 mm zero-degree optics attached to a camera was introduced through it. The placement of the second access port was video assisted. For ovary exposure, the patients were positioned in lateral recumbency on the contralateral side to the ovary being removed. The miniloop was composed of a 2 mm diameter minitrocar, a 1.8 mm knot pusher, and a pre-tied slipknot. It was introduced percutaneously at the lateral abdominal wall. It was inserted attached to a pre-tied loop ligature.[...]

Whereas intrauterine deposition of semen is essential to obtain high rates of fertilization, the aim of thisstudy was to develop a new technique of video-assisted transcervical artificial insemination. It was used a rigidendoscope with 17.5 cm by 2.5 mm of diameter to facilitate the passage of cervical rings and allow intrauterinedeposition of semen. The frequency of types of cervical ostium was 40%, 30%, 20% and 10%, beeing papilla,smooth, flap and rosettes respectively. The average penetration was 1.4 ± 0.96 cervical rings, and the access tothe uterus was impossible in 100% of animals, semen was deposited on superficial cervical region in 90% ofanimals and 10% in the mean cervical region, average time of passage was 4' and 10'', obtaining 10% ofpregnancy rate. It was concluded that the studied technique requires adaptations as semi-flexible and smaller indiameter optics to provide better results.(AU)

Background: Laparoscopy provides good visualization of horses abdominal cavity, besides providing minimal invasiveness and meticulous manipulation intra-abdominal organs. Laparoscopy is suitable for both diagnosing and treating acute abdomen in horses. The purpose of this study was to report a successful case of laparoscopic-assisted surgery for treating sand impaction in a horse.Case: A 3-year-old horse, weighing 460 kg, was admitted following chronic intermittent episodes of diarrhea and colic. Physical exam revealed mild abdominal pain and liquid/pasty diarrhea. There was negative survey of gastrointestinal helminthes and microbiological analyses. Fecal sedimentation test revealed sand impaction. Surgical approach was opted for both accomplishment of the abdominal exploration and resolution of the impactation. The patient was anesthetized and positioned in dorsal recumbency. Laparoscopy was performed through an 11-mm trocar placed right cranially to the umbilicus. There were no apparent adhesions, bowel inflammation nor visceral displacement. A 15-cm celiotomy was carried out caudally to the umbilicus, under laparoscopic guidance, for initial inspection of the gastrointestinal tract. Incision enlargement was required for exteriorizing the pelvic flexure. Afterwards, enterotomy was carried out for drainage of the impactating content, followed by enterorraphy. The pelvic flex...(AU)
