Utilização do laboratório clínico como ferramenta de diagnóstico de enfermidades do sistema digestório de bovinos.

Abstract

Use of the clinical laboratory as a tool in the diagnosis of diseases of the digestive dystem bovine. The objective of this work to present a theoretical framework about the importance of the clinical laboratory as an auxiliary diagnostic tool, useful laboratory tests in the diagnosis of diseases of the digestive system of ruminants and evaluate the use of clinical laboratory as a means aid in the diagnosis of diseases of digestive system of cattle examined at the Veterinary Hospital of UFCG in the period January 2008 to December 2013. laboratory tests laboratory provide subsidies to physicians to confirm or not certain diagnosis, assess the severity of a disease, develop guidelines for the therapeutic management to be carried out, to determine the new tests, prognosis, detect diseases by screening and monitoring therapy. However, there are several common types of inadequacy in the solicitation of the tests, as the repetition of recent tests and test requests that are not consistent with the clinical state of the animal. In the case of gastrointestinal diseases recommended profile includes hematocrit, total plasma protein, sodium, potassium, chloride, calcium, glucose, urea, creatinine, peritoneal fluid cytology, fecal occult blood, fecal parasite research, ruminal pH, blood gas analysis, blood pH and serum bicarbonate. Liver profile should detect active hepatic damage, involvement of the biliary system or changes in liver function. The diseases of the digestive system cause hematological changes in serum chemistries, renal function, liver, urine and rumen fluid that can be identified in laboratory tests, which are important aids in the establishment of diagnostic tests. The requests for

tests at the Veterinary Hospital of UFCG are flawed, particularly with regard to non- solicitation of serial measurements of blood counts and serum biochemical, and utilization

of tests that are not consistent with the clinical picture of the animal. Furthermore, the lack of equipment for performing blood gas analysis and are ionograms is a serious problem in HV. It is necessary to establish in the ambulatory of large animal protocol requests for examinations for diseases of the digestive system as well as to other systems.
