O projeto Carroceiro, coordenado e idealizado pela Profa. Dra. Renata Gebara Sampaio Dória, iniciou suas atividades no ano de 2011 e, desde então, vem contribuindo com muitas famílias de Pirassununga e região que utilizam equídeos para tração e não possuem condições financeiras para fornecer a seus animais uma assistência médica veterinária. O trabalho objetiva a conscientização dos proprietários dos equídeos utilizados em carroças (carroceiros) sobre: zoonoses, saúde pública, manejo, bem-estar e promoção da saúde desses animais, que são utilizados para tração como fonte de subsistência por muitas famílias. Além de promover a saúde e bem-estar dos animais, bem como a conscientização dos carroceiros, o projeto auxilia os estudantes de Medicina
Background: Obstructive urinary tract disease in horses is a rare and low prevalence pathology in the species, but potentially severe. It is an emergency condition that presents variable clinical signs and depends on the anatomical location of the obstruction. The bladder calculus are the most common followed by the urethra and less commonly seen are the kidney or ureteral. The main crystalloid component of uroliths in horses is calcium carbonate. The higher prevalence of urolithiasis in male horses is justified by some anatomical differences between genders. The urethra of males is narrower and longer than that of females. The tissue injury is the most important factor for the development of uroliths in horses. Desquamation of epithelial cells, presence of leukocyte and necrotic cell debris are relevant contributors to crystal growth. Urinary stasis favors nucleation by increasing the chance of contact between crystalloid material and urinary epithelium. Once crystal growth has begun, the urine alkalinity of the equines favors the crystallization and further deposition of other components, especially calcium carbonate. Typical clinical signs of urolithiasis include tenesmus, dysuria, strangury and polaquiuria. Hematuria is often present, mainly observed after exercise and at the end of urination. In addition signs of colic are quite frequent in the acute bladder and urethral urolithiasis due to bladder distension. Upper urinary tract surgery may be technically challenging due to limited structural exposure, especially in adult horses The prognosis for horses with urolithiasis depends on the location of the urolith and the degree of renal injury that occurred.Case: This report aims to describe a rare case of obstructive urolithiasis in a 8-year-old castrated male horse with 24 h evolution. The horse was expressing signs of abdominal pain and during the transretal examination through palpation, it was possible to notice great distension and turgidity of the bladder, in addition to a high pain sensitivity to the palpation of the kidneys. Was perform urethral catheterization, but it was unproductive. The diagnosis was made through perineal ultrasonography and treated surgically by perineal urethrotomy. The animal presented an excellent evolution after being discharged after 10 days of hospitalization and did not present any complication or recurrence of the disease after one year of the procedure.Discussion: Urolithiasis in horses has a prognosis dependent on the location of the urolith and the degree of renal damage. Cases of obstructive urolithiasis in horses are rare and require prompt and appropriate intervention. Therefore, a rapid and accurate diagnosis is directly related to the success of the treatment. In the present case, the animal had characteristic clinical signs of an acute abdomen. Transrectal palpation, for evaluation of the intestinal portions, was important to diagnose an excessively distended urinary vesicle with no intestinal changes. Transcutaneous ultrasonography of the perineum allowed visualization of the calculus, and then a case of perineal urolithiasis was diagnosed. The choice for perineal urethrotomy was performed because of the ease of palpation of the calculus through the skin below the anus and because it is a non-invasive technique. The urethra was sutured to guide the cicatricial process and the urethral catheter was maintained, reducing the risks of occlusion of the urethral lumen.

This study assessed the impact of different recumbency on sevoflurane-anaesthetised sheep. Seven female sheep were premedicated with 0.1 mg.kg-1 butorfanol and subsequently administered a combination of 3 mg.kg-1 ketamine and 0.5 mg.kg-1 midazolam. Animals were maintained on sevoflurane anaesthesia with pressure-controlled ventilation (12 cm H2O peak inspiratory pressure) and ƒ of 10 mpm. During the anaesthetic procedure, animals underwent one out of three different recumbency: dorsal, left lateral, or right lateral positions. Treatments lasted 120 min with a 48-h washout period in between the treatments. Arterial and central venous blood samples were withdrawn for blood gas and electrolytes analysis and pulmonary shunt fraction (Qs/Qt) CaO2, CcvO2, and CcO2 were calculated accordingly. Results showed that Qs/Qt greatly decreased from 0 to 120 min in all the groups (dorsal: 69.3% to 27.3%; left lateral: 59.1% to 25.0%; right lateral: 67.2% to 32.4%). CaO2, CcvO2 and CcO2 improved over time points, with no difference among treatments. PaO2 and PAO2 showed higher values for 60 and 120 min compared to the 0 min value in all groups, with no differences among treatments as well. PaCO2 and ETCO2 in the lateral groups were higher than those in the dorsal group at 120 min. Pressure-controlled ventilation improved gas exchanges in sheep, thereby reducing pulmonary shunt. Recumbency did not interfere with pulmonary shunt, nevertheless, special attention must be paid to lateral recumbency.
