title: [An improved method for the intra-amniotic instillation of a hypertonic saline solution].
abstract: A method for intra-amniotic instillation of hypertonic saline by puncture through the posterior fornix under ultrasound control is described. An ultrasound apparatus with vaginal transducer of 7 megahertz, produced by the firm Brüel and Kjaer, is used. According to the experience in interruption of 22 pregnancies during the second trimester because of medical indications the method has the following advantages: the manipulation is connected with much less unpleasant sensations of the pregnant women in comparison with the original method of Aburel-Atanasov. No vaginal retractors are used and the cervix is not seized and pull with in an instrument outside. Success is achieved even after the first puncture, since the movement of the needle in the uterine cavity is observed by on the ultrasound screen and is directed to a site, optimal for instillation of saline. The risk of tissue necrosis, caused by saline administered in the uterine wall, in the intestinal wall, in the urinary bladder, or in peritoneal space is reduced considerably. It is stressed that it is necessary that the operator should know very well the technique of ultrasound examination of the amniotic sac and to have experience in manipulation under ultrasound control.
