AbstractThe development of vaginal ultrasound transducers has facilitated ovum pick-up (OPU) by providing higher precision and less trauma than are found with laparoscopy and other ultrasound-assisted techniques. In order to evaluate the patients' acceptance, 65 patients were asked to answer a questionnaire about their experience with the procedure. The punctures were executed with specially designed needles introduced through a needle guide attached to a vaginal transducer with a frequency of 7 MHz (Brüel & Kjaer, Denmark). The anesthesia consisted of a light premedication and a paracervical block. If needed, a small dose of sedative was given intravenously intraoperatively. The patients classified their pain experience within the day of the puncture on a four-grade scale. Their statements were compared to the physician's opinion of the discomfort caused. Oocytes were retrieved from all patients. Fifty-one patients answered the questionnaire, of whom five found the OPU painful. In two cases the physician underestimated the patients' pain experience. The mean time required for the procedure was 16 min/OPU. We conclude that transvaginal ultrasound-guided OPU is well accepted by most patients under local anesthesia and that it is a rapid and accurate procedure.
