Intraoperative fluid therapy for video-assisted ovariohysterectomy in dogs.

BACKGROUND: Intraoperative fluids are still poorly studied in veterinary medicine. In humans the dosage is associated with significant differences in postoperative outcomes. OBJECTIVES: The aim of this study is to verify the influence of three different fluid therapy rates in dogs undergoing video-assisted ovariohysterectomy. METHODS: Twenty-four female dogs were distributed into three groups: G5, G10, and G20. Each group was given 5, 10, and 20 mL·kg-1·h-1 of Lactate Ringer, respectively. This study evaluated the following parameters: central venous pressure, arterial blood pressure, heart rate, respiratory rate, temperature, acid-base balance, and serum lactate levels. Additionally, this study evaluated the following urinary variables: urea, creatinine, protein to creatinine ratio, urine output, and urine specific gravity. The dogs were evaluated up to 26 h after the procedure. RESULTS: All animals presented respiratory acidosis during the intraoperative period. The G5 group evidenced intraoperative oliguria (0.80 ± 0.38 mL·kg-1·h-1), differing from the G20 group (2.17 ± 0.52 mL·kg-1·h-1) (p = 0.001). Serum lactate was different between groups during extubation (p = 0.036), with higher values being recorded in the G5 group (2.19 ± 1.65 mmol/L). Animals from the G20 group presented more severe hypothermia at the end of the procedure (35.93 ± 0.61°C) (p = 0.032). Only the members of the G20 group presented mean potassium values below the reference for the species. Anion gap values were lower in the G20 group when compared to the G5 and G10 groups (p = 0.017). CONCLUSIONS: The use of lactated Ringer's solution at the rate of 10 mL·kg-1·h-1 seems to be beneficial in the elective laparoscopic procedures over the 5 or 20 mL·kg-1·h-1 rates of infusion.

Therapeutic Aspects of Dogs with Presumptive Diagnosis of Idiopathic Epilepsy

Background: Epilepsy is a chronic neurological condition characterised by recurrent epileptic seizures. Various antiepileptic drugs are used for the management of canine idiopathic epilepsy. Phenobarbital is the drug of choice for long-term treatment in dogs. Although it is well tolerated, phenobarbital can cause liver injury if administered alone or in combination with other drugs. Therefore, the main of this study was to identify dogs with presumptive diagnosis of idiopathic epilepsy and information about the antiepileptic drugs, the dose and frequency of administration, period of treatment, frequency of the seizure before and after start the treatment, complementary exams and adverse effects.Materials, Methods & Results: In this study were included 21 dogs with idiopathic epilepsy. All dogs were examined and having blood taken for blood count, biochemical tests (ALT, AST, AP, total protein, albumin, creatinine, urea, amylase, lipase, cholesterol and triglycerides), measurement of serum phenobarbital and/or potassium bromide and, some dogs, free T4 by dialysis and canine TSH. In this study, it was observed monotherapy (phenobarbital) in 76.19% (16/21), double therapy (phenobarbital and potassium bromide) in 19.05% (4/21) and triple therapy (phenobarbital, potassium bromide and gabapentin) in 4.76% (1/21) of dogs. The phenobarbital was used as monotherapy with dose between

Presumptive diagnosis of fibrocartilaginous embolism in 12 dogs / Diagnóstico presuntivo de embolismo fibrocartilaginoso em 12 cães

Background: Fibrocartilaginous embolic myelopathy is a syndrome of spinal cord infarction caused by fi brocartilaginous emboli identical to the nucleus pulposus of intervertebral disk. The signals were acute and not progressive, asymmetric in 92% and neuroanatomic regions were affected C6-T2 (n = 2), L3-T3 (n = 5) and L4-S3 (n = 5). The diagnosis was based on history, fi ndings on physical and neurological examination and exclusion of differential diagnosis. The aim of this study was to report twelve dogs treated at Hospital Veterinário Universitário (HVU), Universidade Federal de Santa Maria (UFSM) with a presumptive diagnosis of fi brocartilaginous embolism. Cases: Seven males and fi ve females dogs were referred to the Veterinary Teaching Hospital of the Federal University of Santa Maria: three rottweiler dogs, two labradors retrievers, one fi la brasileiro, one chow-chow, one boxer, one schnauzer, one German shepherd, one mixed breed and one greyhound, aged between one year and three months and eleven. In all cases, the owners reported during the anamnesis partial or complete loss of movement of member(s) involved(s) acutely with no history of trauma. For anatomical localization of the lesion was performed neurological examination. As complementary exams were requested blood count, serum biochemistry, urinalysis, and radiography of the spine.
