What complication can arise from a fetal presentation abnormality during a twin delivery?

A fetal presentation abnormality during a twin delivery can lead to fetal distress due to several factors. In twin pregnancies, the positioning of the fetuses can significantly affect the delivery process. If one or both twins are in a breech position or any non-vertex presentation, this can create complications during labor and impact the oxygenation of the fetuses. The abnormal presentation can lead to cord compression, a prolonged labor, and inadequate uterine contractions, which may compromise the fetal heart rate and lead to distress.

Fetal distress is characterized by signs such as abnormal fetal heart rate patterns, which can signal that the fetus is not tolerating the labor well. This can necessitate immediate intervention, including the potential for cesarean delivery, to ensure both the safety of the fetuses and the mother. Understanding the risk of fetal distress with abnormal presentations underscores the importance of close monitoring during labor in twin pregnancies.
