Vacuum aspiration at therapeutic abortion: blood loss at operation in multigravid women.

Abstract

Therapeutic abortion by vacuum aspiration in the first trimester was carried out on 129 healthy multigravid women. The loss of haemoglobin at operation was estimated and the volume of blood calculated. The figures were compared to those in a group of primigravid women earlier reported. Blood loss increases with gestational length. Blood loss at first trimester abortion is smaller in multigravid than in primigravid women. In multigravid women blood loss is not significantly influenced by the woman's age and the number of pregnancies.
