What is a potential effect of cocaine on uterine activity?

Cocaine use during pregnancy can result in significant changes to uterine activity. Specifically, one of the primary effects is increased uterine activity. Cocaine stimulates the sympathetic nervous system, leading to heightened uterine contractions. This can manifest as increased frequency and intensity of contractions, which is particularly concerning in a laboring patient.

Additionally, the drug can also lead to decreased variability in fetal heart rate patterns. Increased uterine activity can compromise fetal oxygenation, causing the fetus to experience stress. This may result in reduced variability in the heart rate, an indicator of normal fetal well-being.

Understanding these effects is crucial for monitoring and managing the health of both the mother and fetus during pregnancy. In cases where cocaine is involved, healthcare providers must be vigilant in observing uterine activity and assessing fetal heart rate patterns to ensure appropriate interventions are decided upon.
