Study Notes
Hypotonic Uterine Dysfunction Overview
- Hypotonic uterine dysfunction occurs when uterine contractions (UCs) lack sufficient pressure to promote cervical dilation and effacement.
- Women typically progress normally during the latent phase but experience weaker, less effective UCs during active labor.
At-Risk Populations
- Multiparous women (those with multiple births) are at greater risk, as their bodies may remember how to contract but not the necessary intensity.
- Women experiencing extreme fear are also at risk due to catecholamine release, which interferes with UCs.
Risks Associated with Hypotonic Uterine Dysfunction
- Prolonged labor leads to risks such as maternal exhaustion and infection.
- Fetal risks include intolerance and asphyxia.
Measuring Contraction Intensity
- An intrauterine pressure catheter (IUPC) is used to measure the exact intensity of contractions.
- The Montevideo unit is a method to quantify labor contractions, aiming for a score between 200 mmHg and 250 mmHg based on uterine activity.
Montevideo Unit Calculation
- The calculation involves obtaining the peak contraction pressure and subtracting the resting tone.
- If the calculated score is below 200 mmHg, it indicates insufficient contractions, suggesting hypotonic dysfunction.
Assessment Findings
- The uterus is easily indentable, even at the peak of a contraction, indicating hypotonicity.
Medical Management
- Ensure placement of an IUPC and conduct a vaginal exam to assess labor progression and cervical dilation.
- Anticipate administering oxytocin (Pitocin) if the Montevideo score is less than 200 mmHg to stimulate stronger contractions.
Nursing Interventions
- Conduct vaginal exams and calculate Montevideo scores.
- Maintain hydration to address contractions that are too weak.
- Monitor fetal heart rate (FHR) tracing and encourage safe ambulation to strengthen contractions.
- Provide emotional support to reduce fear, promoting stronger contractions.
Important Considerations
- Oxytocin can be administered for hypotonic dysfunction only when ordered. Avoid administering it for hypertonic dysfunction, as those contractions are already excessively strong.
