Indication of amnioinfusion is:a) Oligohydramniosb) Suspected renal anomaliesc) To facilitate labourd) In case of fetal distress
Amnioinfusion is a procedure where saline is instilled into the amniotic cavity. The main indications are usually for oligohydramnios, especially in late pregnancy, to prevent fetal limb compression and improve lung development. Also, it's used during labor if there's meconium-stained amniotic fluid to dilute meconium and reduce the risk of meconium aspiration. But the options here don't mention meconium. Let me check each option.
Option a is Oligohydramnios. That's a classic indication. Oligohydramnios can be due to fetal renal anomalies, but the procedure itself is indicated for the oligohydramnios, not the underlying renal issue. So option b might be a cause, but the indication is the oligohydramnios itself.
Option c, to facilitate labor. That doesn't sound right. Amnioinfusion isn't used to speed up labor; it's more about managing complications. Option d, fetal distress. Fetal distress during labor might be managed with other interventions like cesarean section, not amnioinfusion. Unless the distress is due to meconium aspiration, but again, the options don't specify that. So the correct answer should be a) Oligohydramnios.
Wait, the options are a, b, c, d. The user's correct answer is A. But I need to confirm. Let me recall: Amnioinfusion is primarily indicated for oligohydramnios in the third trimester to prevent complications. Suspected renal anomalies might be a reason for oligohydramnios but the indication is the oligohydramnios itself. So option b is incorrect. To facilitate labor (c) is not an indication. Fetal distress (d) can sometimes be managed with amnioinfusion if it's due to meconium, but the question doesn't specify that context. So the best answer is a) Oligohydramnios.
**Core Concept**
Amnioinfusion is a procedure where sterile saline is instilled into the amniotic cavity. Its primary indications include oligohydramnios (low amniotic fluid) in the third trimester to prevent fetal limb compression and fetal lung hypoplasia, or during labor to dilute meconium and reduce aspiration risk.
**Why the Correct Answer is Right**
**Option A (Oligohydramnios)** is correct because amnioinfusion is a standard intervention for oligohydramnios, particularly when caused by fetal renal agenesis or intrauterine growth restriction. The procedure increases amniotic fluid volume, alleviating pressure on fetal structures and promoting normal development. It is also used during labor with meconium-stained fluid to minimize meconium aspiration syndrome.
**Why Each Wrong Option is Incorrect**
**Option B (Suspected renal anomalies):** Renal anomalies may
