What should be monitored if there is a suspicion of a kinked intrauterine pressure catheter?

When there is a suspicion of a kinked intrauterine pressure catheter, it is essential to monitor fetal heart rate variability. This is because a kinked catheter can lead to inaccurate readings of uterine pressure, which is crucial in assessing the strength and frequency of contractions. If the catheter is compromised, it may not reflect the true intrauterine pressure, potentially misleading the clinical assessment of how well the fetus is tolerating contractions and the overall labor progress.

Monitoring fetal heart rate variability provides key insights into the fetal well-being. A healthy fetus typically exhibits a certain range of variability in heart rate, which indicates a responsive and well-oxygenated state. A loss of variability can suggest that the fetus may be experiencing stress or hypoxia, possibly related to ineffective contractions indicated by a kinked catheter. Therefore, tracking the variability of the fetal heart rate becomes a critical part of ensuring the safety of the fetus during labor when a kink in the catheter is suspected.
