[The clavicular fracture--a questionable achievement in modern obstetrics].

The increase in fractures of the clavicle as a birth trauma at the Innsbruck University Gynecological Clinic in the last decades, which was substantial in contrast to the improvement in perinatal mortality and morbidity, indicated an analysis of the reason. With the exception of the high average birth weights, the causal factors crystallised out, in the broadest sense, as being related to the control and direction of labour. The anticipated fetal distress condition at the end of the expulsion period proved to be of primary importance. This resulted in a too early and traumatic delivery, which could not be justified by the good navel arterial pH and Apgar values. By observing certain procedures, it was possible to reduce the frequency of fractures of the clavicle in spontaneous births from 2 to 1.25% maintaining the same fetal outcome.

Determination of light-chain myosin in pregnancy and under tocolysis.

Cardiac toxicity of tocolysis containing hexoprenaline (0.3 microgram/min) and the beta 1-blocking agent metoprolol (0.01 mg/min) was investigated using a recently developed monoclonal antibody arised against light-chain myosin in 15 patients and compared with the results in 51 control subjects. There was an increase in the median and 80th percentile values 2, 6, 12 and 24 hours after the beginning of tocolysis but no statistically significant difference between these values and the normal ones could be shown.

Single doses of catecholamines in the rat: catecholaminotropic, but not hyperglycemic.

1. As in two "lower" vertebrates, the lamprey and the eel, single intravascular injections of physiological doses (2.5 micrograms/kg) of epinephrine (E) into the rat immediately increased levels of plasma dopamine (DA) and norepinephrine (NE). 2. Single doses of DA (5 micrograms/kg) enhanced circulating NE and E, while NE (5 micrograms/kg) had no clear impact on the plasma levels of the other two catecholamines (CAs). 3. These data are at variance with findings in the eel, where all three CAs are mutually stimulatory; and in the lamprey, where only E stimulates release of the other two CAs. 4. It appears that E-stimulated CA release is widespread or ubiquitous among vertebrates, and that complex interactions between circulating CAs must be considered under experimental, physiological, and clinical conditions. 5. None of the injections had a significant hyperglycemic effect.
