Oligohydramnios
Pronunciation: OH-li-go-hy-DRAM-nee-ohs
Decreased amniotic fluid volume that may complicate fetal positioning and anesthetic management.
Full Definition
Oligohydramnios refers to abnormally low amniotic fluid volume, typically defined as an amniotic fluid index below 5 cm or deepest vertical pocket less than 2 cm. This condition affects obstetric anesthetic management by potentially increasing the risk of fetal compression during contractions and may necessitate closer fetal monitoring during labor analgesia. Positioning considerations become important as maternal position changes may more significantly affect fetal well-being when protective amniotic fluid is decreased. The underlying cause of oligohydramnios may also influence anesthetic planning, particularly if associated with fetal anomalies or growth restriction.
Usage
Usage note: Always document impact on positioning and monitoring requirements in anesthetic records.
