Introduction

The concept of measuring intrauterine contractions strength was first proposed in 1949, and eventually published in 1952. The use of an IUPC is well ingrained in modern obstetrical/intrapartum practice. Even though it is so commonly performed, we tend to forget some potential limitations and possible risks of this procedure. In this episode, we will review the history and purpose of the IUPC and remind ourselves of some real (though rare) limitations and risks. We will also touch on an evolving, new alternative to intrapartum uterine monitoring: electrical uterine monitoring (EUM). This is electromyography (EMG) of the uterine muscle activity as a contraction monitoring technique.
