Although it has been demonstrated that a combination of mifepristone and a prostaglandin is an effective method of inducing abortion in early pregnancy, the optimum dose of the antigestogen is unknown. Women (n = 220) requesting abortion in early pregnancy (< or = 63 days amenorrhoea) were randomized to receive a single dose of either 600 or 200 mg mifepristone followed 48 h later by a single dose of 600 micrograms misoprostol by mouth. The percentage of women who had a complete abortion (93.6% confidence interval 90.4-95.5%) was identical in the two groups. There was no significant difference in the number of women who passed the fetus within 4 h of receiving the prostaglandin (64 versus 74%), the days of bleeding (14.6 +/- 1.1 versus 15.3 +/- 0.9) nor in the onset of the next period (39.7 +/- 1.3 versus 36.7 +/- 1.3) respectively between the groups receiving 200 or 600 mg mifepristone. However, the complete abortion rate was significantly higher in women < or = 49 days compared to women 50-63 days amenorrhoea (97.5 versus 89.1% respectively; P < 0.02). There was no difference in any of the other parameters at different weeks of gestation. We conclude: (i) that the recommended dose of mifepristone could be reduced from 600 to 200 mg without loss of clinical efficacy, (ii) that the combination of mifepristone and 600 micrograms misoprostol is a highly effective alternative to vacuum aspiration for inducing abortion in women < 50 days amenorrhoea and (iii) at gestation > 56 days, this combination may result in too many incomplete abortions to be clinically acceptable.
Our data showed better subjective cure rates and substantial improvement rates without any significant increase in intraoperative complications with increasing age. Postoperative complications of urgency and vaginal wall erosion were more common in the older aged patients but were easily resolved. Hospital stay and recovery period were short, making TVT a suitable procedure for all ages.
Intracervical injection of prilocaine and felypressin reduces the intensity of pain experienced in women undergoing cervical biopsy and treatment with the Semm coagulator. Its use is commendable but is not absolutely necessary in all cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
