Resumo
As onfalopatias constituem em conjunto de enfermidades, associadas a infecção dos remanescentes umbilicais, que acometem bezerros, levando a prejuízos econômicos e podendo levar o animal a óbito ou comprometer o crescimento e rentabilidade do sistema produtivo. São divididas em infecciosas e não infecciosas, sendo que as primeiras tem prognóstico reservado a ruim, logo, a realização do diagnóstico e prognóstico precisos são essências para minimizar os prejuízos com insucessos terapêuticos. Nesse sentido, em face a escassez de publicações com metodologia mais objetiva para elaboração do prognóstico das onfalopatias, foi realizado esse estudo, com 66 casos de bezerros acometidos por onfalopatias infecciosas, atendidos na Clínica de Bovinos campus Garanhuns – Universidade Federal Rural de Pernambuco, no período de janeiro de 2010 a maio de 2021 O objetivo desse trabalho foi identificar variáveis obtidas a partir do exame clínico e laboratorial em bezerros acometidos por enfermidades umbilicais infeciosas que sejam diferentes entre os animais que tiveram recuperação dos que vieram a óbito ou foi indicada eutanásia. Consiste em estudo de coorte retrospectivo, onde foi realizado a compilação dos achados clínicos e laboratoriais, obtidos dos prontuários clínicos. As variáveis obtidas na admissão hospitalar e o tempo de hospitalização foram comparadas entre animais sobreviventes e não sobreviventes, sendo que as variáveis categóricas foram comparadas utilizando teste de Qui-quadrado ou exato de Fischer, e as variáveis contínuas, passaram por análise gráfica da distribuição, observando-se que todas foram não paramétricas, sendo comparadas utilizando o teste de Wilcoxon, considerando nível de significância de 5%, assim como para as variáveis categóricas. As variáveis hematócrito, hemácias, hemoglobina, fibrinogênio plasmático e neutrófilos bastonetes diferiram significativamente entre os sobreviventes e não sobreviventes. Sendo que das variáveis categóricas apenas a presença de escore de condição corporal menor ou igual a 2 apresentou um valor de P=0,06, próximo ao nível de significância estatística. Conclui-se que os valores de hematócrito, hemácias, hemoglobina, fibrinogênio plasmático e neutrófilos bastonetes são maiores em bezerros acometidos por onfalopatias infecciosas que apresentam evolução clínica durante o tratamento para o óbito ou indicação de eutanásia.
Umbilical diseases are a group of diseases associated with infection of the umbilical remnants, which affect calves, leading to economic losses and possibly leading to death. Given the scarcity of studies with a more objective methodology to elaborate the prognosis, this study was carried out, with 66 cases of calves affected by infectious umbilical diseases, treated at the Clinic of Cattle campus Garanhuns - Federal Rural University of Pernambuco, in period from January 2010 to May 2021 The objective of this study was to identify variables obtained from the clinical and laboratory examination in calves affected by infectious umbilical diseases that are different between animals that recovered from those that died or that euthanasia was indicated. It consists of a retrospective cohort study, in which the compilation of clinical and laboratory findings was carried out, obtained from the clinical records of 66 calves. The variables obtained on hospital admission and length of hospital stay were compared between surviving and non-surviving animals, and categorical variables were compared using the Chi-square test or Fisher's exact test all numerical variables were non-parametric, being compared using the Wilcoxon test, considering a significance level of 5%, as well as for categorical variables. Variables hematocrit, red blood cells, hemoglobin, plasma fibrinogen, and immature neutrophils differed significantly between survivors and non-survivors. Of the categorical variables, only the presence of a body condition score less than or equal to 2 presented a value of P=0.06, close to the level of statistical significance. It is concluded that the values of hematocrit, red blood cells, hemoglobin, plasma fibrinogen and immature neutrophils are higher in calves affected by infectious umbilical diseases that present clinical evolution during treatment to death or indication for euthanasia.
