[Experiences of pregnant women with ultrasonic examination].

655 pregnant women answered a questionnaire after routine ultrasound examination around the 17th week of pregnancy. Every second woman received written information about ultrasound examination in pregnancy. 37 women answered inconsistently and were withdrawn from the study. 435 (70%) women out of 618 were satisfied with the information they had received on ultrasound examination in pregnancy, although 171 of them had not received our letter of information. Only 26 out of 290 women who had received the information did not consider it to be satisfactory. 252 (40%) admitted being anxious prior to the examination, but we found no relation between anxiety and receiving or not receiving the letter. 584 (95%) answered that they felt more secure after the ultrasound examination and 609 (99%) were satisfied with the information they had received during the examination. All the women wanted to have a routine ultrasound examination during a possible subsequent pregnancy.
