[The diagnostic value of venous blood gas parameters and pH value in newborn foals with pulmonary diseases].

This research paper examines the diagnostic value of venous blood gas parameters for identifying pulmonary disorders in newborn foals. The study demonstrates that there are significant differences between the blood gas parameters of healthy foals and foals with respiratory issues.

Research Methodology

• The study took blood samples from 24 newborn foals ranging between 1 to 6 days old.
• Both venous and arterial blood were tested for partial pressure of oxygen (pO2), partial pressure of carbon dioxide (pCO2), pH, and oxygen parturition (S-O2).
• The study also calculated the alveolar (A) to arterial (a) gradients (A-aDO2).
• Due to changes in blood gas parameters during the first week of a foal’s life, the age of the foal was also considered during the analysis.

Findings

• Arterial blood gas parameters, with the exception of paCO2, showed significant differences between healthy foals and those with respiratory disorders.
• A-aDO2 and paO2 were identified as the most reliable arterial parameters to differentiate between healthy and sick foals.
• For venous blood, only S-O2 and pH showed significant variations between healthy and sick foals.

Implications

• This research suggests that arterial blood gas parameters, specifically A-aDO2 and paO2, are crucial indicators of respiratory disorders in neonatal foals.
• The study also points out the potential importance of S-O2 and pH levels in venous blood as potential diagnostic indicators for these disorders.

Limitations

• The sample size of the study was limited to 24 foals, and the analysis was constrained by the variations in blood gas parameters during the first week after birth.
