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.
对129名健康经产妇进行了孕早期真空吸引术人工流产。估算了手术时血红蛋白的损失量并计算了出血量。将这些数据与先前报道的一组初产妇的数据进行了比较。出血量随孕周增加而增加。孕早期人工流产时经产妇的失血量比初产妇少。在经产妇中，失血量不受产妇年龄和妊娠次数的显著影响。
