[Acid-base balance in the newborn infant. II. 3 technics of sample collection and the difference between amniotomy].

The study included 32 healthy newborns to evaluate the acid-base balance between two groups of newborns whose mothers underwent early or late amniotomy. The results were compared to the first study finding important differences, unquestionable due to amniotomy and age. Significant difference was found only in PO2 between arterial blood and arterialized capillary showing difference in pH, PCO2 and CO2 between the two capillaries.
