[Creatine kinase and creatine kinase isoenzymes in the serum of newborn infants. 1. Effect of the mode of delivery on total CK and CK-B].

The total CK-, CK-B- and CK-M-activity was determined in 48 newborns from the first to the third day of life by use of the "CK-Monotest" (Boehringer Mannheim). Opposite to a very small decrease of the total CK-activity a significant decrease of the CK-B is evident in the same time. At the first day the detection of CK-B was impossible in only 1 of 27 patients, but at the third day a low CK-B level was detectable in only 5 of 11 test persons. The activities of total CK and the CK-B were determined based upon these investigations in 245 newborns at the first day of life by use of the "CK-Monotest NAC activated" (Boehringer Mannheim). There was no significant difference of total CK- and CK-B-activity dependent on the mode of delivery (spontaneous vertex presentation, forceps delivery, caesarean section, breech presentation.) The proportion of the CK-B varied between 8 and 11% of the total creatine kinase in dependence on the mode of delivery.

[Comparative study of oxygen tension in arterial blood and arterialized capillary blood in relation to the oxygen content of inspired air in healthy newborn infants].

The values of oxygen tension of arterial blood were compared with those of arterialized capillary blood in 65 healthy newborns. The latter ones always had a significantly lower level than the arterial ones. A sufficient correlation between paired values could be stated only under conditions of normal room air. With increasing FiO2 (0.4, 0.6, 1.0) the capillary oxygen tension remains behind the arterial one. Giving pure oxygen the capillary tension is nearly half of the arterial value.
