Measurement of Uterine Blood Flow in Non‐Pregnant Women by Electromagnetic Flowmeter: Effect of oxytocin

Abstract

Abstract. Blood flow in one uterine artery was measured by the electromagnetic flowmeter method in non‐pregnant women undergoing surgery. Due to difficulties in dissecting and exposing the uterine artery, statisfactory signals for estimating blood flow were obtained in only 10 out of 22 patients. Most of them had uterine myomas. Mean blood flow in one uterine artery was found to be 53.5 ml/min. After injection of oxytocin blood flow was reduced to 22 to 74% of controls, except in one patient, where no flow change was observed. Methergin administered in 3 patients caused no changes in uterine blood flow.
