Investigations about the diagnostic value of venous blood gas parameters in newborn foals with respiratory disorders [German]

摘要

Analysis of blood gases in equine neonatology is regarded as a diagnostic tool to study the neonatal adaptation period. Aim of this study therefore was to compare the diagnostic value of venous blood gas parameters to arterial parameters in newborn foals with pulmonary disorders. Venous as well as arterial blood samples were taken from 24 foals (1 to 6 days old) and the partial pressure of oxygen (pO(2)), partial pressure of carbon dioxide (pCO(2)), pH, and oxygen parturition (S-O-2) of these samples were investigated. In addition, the alveolar (A) to arterial (a) gradients (A-aDO(2)) were calculated. Due to changes in blood gas parameters during the first week postnatal the age was taken into consideration by using covariance analysis. All arterial parameters except p(a)CO(2) showed a significant difference among healthy foals (n = 15) and foals with respiratory disorders (n = 11) with A-aDO(2) and p(a)O(2) being the most reliable arterial parameters. In venous blood there was a significant difference between healthy and sick foals only in S-O-2 and pH.
