The clinical evaluation of diagnostic prostaglandin test

An oral prostaglandin test with PGE2 in a dose 0.5 mg was performed on 44 women in the last week of pregnancy. During 30 minutes of cardiotocographic recording, two types of contractile activity of the uterus were observed: regular and irregular. Women with regular uterine activity have statistically significantly higher serum oxytocinase level and also a shorter duration of labour. Thus, these two types of uterine activity may also be distinguished by enzyme as well as labour data.
