Efeitos do fentanil, droperidol e inoval sobre função renal e eletrólitos (sódio e potássio)

The influence of Fentanyl, Droperidol and Innovar on renal function and electrolytes (sodium and potassium) were studied on 18 dogs. Fentanyl disturbs kidney function and decreases plasmatic potassium. Droperidol and Innovar do not disturb the main renal function but decrease plasmatic potassium. The results obtained point out the importance of associate employment of Fentamyl and Droperidol, since the latter seems to establish the renal disorders occasioned by Fentanyl, probably owing to its adrenergic α blocking action.

Insuficiência renal aguda. Estudo do quadro clínico e prognóstico.

Acute renal failure (ARF) is a frequent complication in hospitalized patients, and is strongly related to increase of mortality. PURPOSE: To analyze the clinical outcome and the prognostic factors in hospital acquired AFR. METHOD: A prospective study was performed. Data from 200 patients with established ARF admitted during the period of January, 1987 and July, 1990 were collected. RESULTS: The incidence of ARF was 4.9/1000 admissions. Renal ischemia (50%) and nephrotoxic drugs (21%) were the main etiologic factors. The histologic study done in 43 patients showed: acute tubular necrosis (53%), tubular hydrophic degeneration (16%), glomerulopathies (16%) and other lesions (15%). Dialysis therapy was performed in 101 patients and the main indications were: uremia (67%), hypervolemia (22%) and hyperkalemia (9%). The mortality rate was 46.5% and the most important causes of death were: sepsis (38%), respiratory failure (19%) and multiple organs failure (11%). Treatment withdraw was the cause of death in 2 patients. Higher mortality was observed in oliguric patients (62.9%) than non-oliguric (34.5%) (p < 0.05) and in ischemic renal failure (56.7%) when compared to nephrotoxic renal failure (14.7%) (p < 0.05). This difference was maintained when the comparison was done only between dialyzed patients. CONCLUSION: As primary cause of death was not associated to the acute renal failure, we conclude that acute renal failure is an important marker of the gravity of the underlying disease and not the cause of death.

Ritmo sinoventricular secundário a hipercalemia em gatos com obstrução uretral: breve descrição de três casos

Hyperkalemia is a common electrolyte imbalance in cats with obstructive feline lower urinary tract disease (FLUTD). The effects of serum potassium elevation in heart rhythm are serious and potentially lethal. The clinical manifestations reflect changes in the excitability of the cell membrane. Increased potassium levels lead to a reduction of the resting membrane potential of heart muscle cells, making them less excitable and resulting in cardiac arrhythmias. The sinoventricular rhythm with atrial arrest is among the types of arrhythmias caused by hyperkalemia. The purpose of this report was to highlight the importance of electrocardiographic monitoring for the early detection of potentially lethal arrhythmias in cats with obstructive FLUTD. We hereby describe the occurrence of three cases treated at the Small Animal Clinic of FMVZ/Unesp, Botucatu Campus.
