Epidural Catheterization

This is a prospective observational study conducted at the University Hospital of Padua. The goal is to identify ultrasound markers that can help predict whether placing an epidural catheter during labor will be difficult. Pregnant women who request epidural analgesia will undergo a quick ultrasound scan of their lower back before the procedure. The study will collect information such as age, weight, height, and spinal anatomy, as well as ultrasound measurements. This information will be compared with how easy or difficult it was to place the epidural. The study does not involve any experimental treatment and uses standard care procedures already in place. There are no additional risks or costs for participants.
