Failed early medical abortion: beware of the uterine scar!--Case report.

Objectives: To increase awareness of the possible existence of a morbidly adherent placenta in case of failed early medical abortion.

Case: We report a case of placenta increta which caused a massive haemorrhage during surgical aspiration following a failed medical abortion.

Conclusion: Women with a history of caesarean section, who do not respond to a medical regimen for early termination of pregnancy should undergo an ultrasound examination to establish whether this may be due to a placenta accreta, increta or percreta.

A double-blind, randomized controlled trial of the use of a 50:50 mixture of nitrous oxide/oxygen in legal abortions.

Background: The study was conducted to evaluate the effectiveness of oxygen/nitrous oxide (O(2)/N(2)O) in elective abortions by vacuum aspiration with paracervical block and intravenous paracetamol.

Design: This single-center double-blinded randomized study tested O(2)/N(2)O (n=36) and placebo (air, n=36) for additional analgesia in elective abortions with paracervical block and intravenous paracetamol. We assessed intra- and postoperative pain according to both a visual analogic scale rated from 0 to 10 and postoperative analgesic requirements.
