Abstract

The parameters of acid-base balance were investigated in relation to the time difference between the blood sampling and the examination and ambient temperature in the field conditions. The transfer of the samples from field conditions to a laboratory was imitated by putting the case with the samples into a thermostat at the temperature of 20 degrees C and 37 degrees C. In the first trial, at the temperature of 20 degrees C, statistically significant changes in pH values were recorded in seven hours. If the temperature in the case was 37 degrees C, the differences in pH, BE, SBi and BB values and in the partial pressure of CO2 were statistically significant in six hours. Applying the above results we state that the acid-base parameters can be examined within five hours after blood sampling supposing that the blood samples are kept at the temperature of 0-4 degrees C and using for veterinary diagnostics the equilibration method after Astrup.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
