[Ovulation inhibitors and postoperative hazards of pulmonary embolism]. / Ovulationshemmer und postoperatives Lungenembolierisiko.

PIP: A collective of 8152 women operated on from 1963 to 1969 was analyzed for postoperative pulmonary embolisms. Of the 6927 women who had never taken ovulation inhibitors, 26 (.38%) suffered postoperative lung embolisms; of the 1225 women who had been on oral contraceptives at least 3 months, only 1 had pulmonary embolism (.08%). Morbidity showed the same tendency, with 3 fatal embolisms, all in women never medicated with ovulation inhibitors. There was a significant, statistically demonstrable increase in oral contraceptive users in the later years of the survey. The demonstrated lower risk of postoperative lung embolism in this study should be tested in a greater number of subjects.^ieng
