Final answer:
CTGs record fetal heartbeats and uterine contractions. Late decelerations are a sign of potential fetal distress, often seen in growth restricted fetuses. Oligohydramnios (reduced amniotic fluid) can worsen this condition.
Step-by-step explanation:
Late decelerations in a CTG (Cardiotocography) refer to a pattern of delayed or reduced fetal heart rate in response to a uterine contraction, indicative of potential fetal distress. This pattern is often observed in growth restricted fetuses, like the 32-week fetus mentioned in the question. Oligohydramnios, or reduced amniotic fluid, can complicate the condition, as it indicates less cushioning and protection for the fetus and can also lead to growth restrictions. By understanding these signs on a CTG, health professionals can take necessary measures to ensure fetus safety.
A late deceleration in a cardiotocography (CTG) is a finding that indicates fetal distress during pregnancy. It is characterized by a decrease in the fetal heart rate below the baseline, which occurs after the start of a contraction and lasts for at least 15 seconds.
In this specific case, the CTG was from a 32-week growth-restricted fetus with oligohydramnios. Growth restriction refers to a condition where the fetus is not growing at the expected rate, while oligohydramnios refers to a decrease in the amniotic fluid volume surrounding the fetus.
These findings suggest that the fetus may be experiencing inadequate oxygen supply and may require further medical evaluation and management.
