[Serum myoglobin in long-term tocolysis (a radioimmunological determination method) (author's transl)]. / Serum-Myoglobin bei Langzeittokolyse (eine radioimmunologische Bestimmungsmethode).

In order to establish early recognition of possible myocardial damage during long-term tocolysis with beta-sympathomimetics, the serum myoglobin level was additionally determined along with the CKMB serum level in 65 patients. With one exception, all myoglobin values were within the normal range of 6-85 ng/ml.

[Serum kreatinkinase MB during fenoterol tocolysis (author's transl)]. / Serumkreatinkinase BM während Fenoterol-Tokolyse.

In the investigation of possible myocardial damage, the assay of the heart specific isoenzyme kreatinkinase MB has established itself as a highly sensitive proof of a heart necrosis. In patients who underwent stationary treatment for premature contractions, the CK-activity was measured in the initial phase of tocolysis and additionally right before the therapy was ended. There was no laboratory indication of any heart damage due to tocolytic treatment.
