O41.03
Oligohydramnios, third trimester
Clinical Classification Guidelines
Medical Intelligence & Overview
Oligohydramnios refers to a condition characterized by a decreased amount of amniotic fluid surrounding the fetus during pregnancy. Specifically, when this condition occurs in the third trimester, it can pose risks for both the mother and the developing baby. The ICD-10 code O41.03 is used by healthcare professionals to identify cases of oligohydramnios occurring in the third trimester. This condition requires careful monitoring and management to ensure the health and safety of both mother and child.
Causes & Symptoms
Clinical Causes: Placental insufficiency: when the placenta doesn't provide enough nutrients and oxygen to the fetus. Fetal urinary tract abnormalities: malformations affecting the baby's ability to produce urine, which contributes to amniotic fluid levels. Rupture of membranes: premature rupture can lead to fluid loss and decreased amniotic fluid. Maternal dehydration: insufficient fluid intake by the mother can reduce amniotic fluid levels. Certain medications: drugs that affect kidney function or blood flow can influence amniotic fluid levels. High blood pressure or preeclampsia: conditions that impair placental blood flow. Fetal demise: in cases where the fetus has died, amniotic fluid often decreases significantly. Multiple pregnancies: increased risk of fluid imbalance in twin or higher-order pregnancies.
Key Symptoms: Reduced or absent pooling of amniotic fluid observed during ultrasound examinations. Fetal growth restriction or slow growth rate. Fetal movements may be decreased or less vigorous. Oligohydramnios may be detected through decreased amniotic fluid index (AFI) or maximum vertical pocket (MVP) measurements during ultrasound. In some cases, no specific symptoms are noticed by the mother until ultrasounds reveal the condition.
Diagnostic & Treatment
Diagnosis Path: Diagnosis primarily involves ultrasound evaluation, which measures the amount of amniotic fluid. Common methods include:
Treatment Protocols: Management of oligohydramnios in the third trimester focuses on monitoring and fetal well-being, with interventions as necessary:
