Six mixed-breed, adult, male horses, weighting 350 to 450 kg were used. The animals were randomly distributed into two (treatments) groups, with each horse receiving both treatments. Sedation with xylazine (1mg/kg, IV), infusion of 10% guaifenesine (100 mg/kg in 5% glucose), induction with S(+)-ketamine (1 mg/kg, IV), and maintenance with halothane (end-tidal concentration of 1.5 MAC) was standardized for both groups. When halothane end-tidal concentration stabilized at 1.5 MAC, CRI with S(+)-ketamine (GrKet) at 0.01 mg/kg/min (diluted in 250 ml of 0.9% saline solution) or the same volume of 0.9% saline solution (GrSal) was initiated (M0). CRI was maintained for 50 minutes (M50). Cardiac output (CO), fractional shortening (FS) and ejection fraction (EF), heart rate (HR), respiratory rate (ƒR), systolic (SAP), mean (MAP) and diastolic (DAP) a...

In the TSR the animals were injected with saline solution (NaCl 0.9%) intravenously simulating the hyoscine volume. Hyoscine (0.14 mg/kg) was administered intravenously in the THR. In both treatments the respective solutions were administered five minutes before the intravenous injection of romifidine (0.08 mg/kg). The ejection fraction, shortening fraction and the cardiac output were echocardiographically analyzed. The blood pressure was measured by catheterization of the left carotid artery. The cardiac function was registered electrocardiographically. The analyzed parameters were measured before (M0) and five minutes after the administration of the saline solution or hyoscine (M1). The parameters were measured at 10 (M2), 15 (M3), 30 (M4), 45 (M5) and 60 (M6) minutes after the romifidine injection. The final results consigned t...

It has been used in females with highly zootechnical valuable. The complications of this technique, despite exceptional, assume great importance and might be of the veterinarian and owner’s knowledge. The purpose of this study is to describe the possible complications of the follicular aspiration considering the Veterinarian Hospital ";Governador Laudo Natel"; of the Faculdade de Ciências Agrárias e Veterinárias UNESP-Jaboticabal 2003-2005 casuistic. In a total number of 16 animals was possible to observe peritonitis, absence of labor signals, offspring death and peritonitis, distocic delivery with premature fetus, genital lesions, presence of vaginal wall abnormal masses and ovarian adhesions.KEY WORDS: Clinical complications, follicular aspiratiorn, Nelore cow. Nos últimos anos, a aspiração folicular transvaginal guiada pela ultra-sonografia ou OPU (ovum pick up), em fêmeas bovinas doadoras de oócitos, tem se tornado uma prática muito difundida e vem sendo utilizada na multiplicação de fêmeas de elevado valor zootécnico. As complicações dessa técnica, mesmo que de ocorrência excepcional, assumem grande importância e devem ser de conhecimento do veterinário e, também, do proprietário. O propósito deste trabalho é descrever as possíveis complicações da aspiração folicular, considerando a casuística do Hospital Veterinário Governador Laudo Natel, da Faculdade de Ciências Agrárias e Veterinárias da UNESP, Jaboticabal, durante os anos de 2003 a 2005. Em um total de dezesseis animais recebidos, verificaram-se a presença de peritonite, a ausência de sinais de parto, morte fetal, parto distócico com feto prematuro, lesões de órgãos genitais, aumento de volume na parede da vagina e aderência ovariana.
