[Legal abortion. An analysis of factors which can affect frequency of complications].

INTRODUCTION

Due to a rather high complication rate, we decided to analyze data from women, who were readmitted to hospital with complications to legal abortion.

MATERIAL

760 legal abortions performed in 1993-1994 were retrospectively reviewed for complications.

RESULTS

We found 66 complications (8.7% (95% confidence limits (6.7-10.7)), that resulted in readmission to hospital. The distribution of complications was as follows: retention 41 (62% (50-74)), infection 12 (18% (9-27)), bleeding and pain 11 (17% (8-26)) and perforation two (3% (0-7)). There was a slight correlation between a stronger midline echo on ultrasound measurement of the uterine cavity and finding placental tissue on histological examination of the material obtained from reevacuation. The time interval between legal abortion and reevacuation was nine days. Retroflexio uteri was not correlated with reevacuation.

CONCLUSIONS

We found a statistically increased risk of complications following legal abortion relative to the figures reported by the national health authority, but not significantly higher than that found in other reports. Moreover, a conservative attitude to retention can reduce the number of reevacuatio uteri after legal abortion.
