In the presence of labor progression, monitoring of uterine contractions by external tocodynamometry is often adequate. However, if a laboring mother is confirmed to have rupture of the membranes and if the intensity/duration of the contractions cannot be adequately assessed, an intrauterine pressure catheter can be inserted into the uterine cavity past the fetus to determine the onset, duration, and intensity of the contractions. Because the external tocometer records only the timing of contractions, an intrauterine pressure catheter can be used to measure the intrauterine pressure generated during uterine contractions if their strength is a concern. While it is considered safe, placental abruption has been reported as a rare complication of an intrauterine pressure catheter placed extramembraneously. [32]
