Patent ductus arteriosus treatment in neonates

Why does the ductus arteriosus close off at the time of birth? When does the PDA close? How does indomethacin close PDA?

This connection is present in all babies in the womb, but should close shortly after birth. In some babies, especially in those born prematurely, this vessel may remain open. This is called a patent or persistent.

Keeping a ductus arteriosus patent is indicated in neonates born with concurrent heart malformations, such as transposition of the great arteries. Drugs such as alprostadil , a PGE-analog, can be used to keep a PDA open until the primary defect is corrected surgically. A meta-analysis by Jones et al confirmed that both indomethacin and ibuprofen treatments promote patent ductus arteriosus (PDA) closure better than placebo. Ibuprofen and indomethacin appear to be equally effective, with similar rates of complications after therapy except for the development of chronic lung disease ( greater risk in ibuprofen treatment arm).

A patent ductus arteriosus might be found while your baby is in the hospital after birth or it might be discovered later as an adult, sometimes because of a heart murmur. Patent ductus arteriosus in preterm neonates PDA is a common diagnosis in extremely preterm infants, especially in those with lung disease. Approximately of infants born at less than weeks of gestation will have persistent patency of the ductus arteriosus and will be assigned the diagnosis of PDA at some time during the early neonatal period.

However, a large patent ductus arteriosus left untreated can allow poorly oxygenated blood to flow in the wrong direction, weakening the heart muscle and causing heart failure and other complications. Treatment options for a patent ductus arteriosus include monitoring, medications, and closure by cardiac catheterization or surgery. The symptoms of a patent ductus arteriosus depend on the size of the ductus and how much blood flow it carries. After birth, if a ductus arteriosus is present, blood will flow from the aorta (the main artery in the body) into the pulmonary artery.

This extra blood flow into the lungs can overload the lungs and put more burden on the heart to pump this extra blood. Some babies may need more. It’s an extra blood vessel that connects arteries: the pulmonary artery and the aorta.

The ductus arteriosus is a normal part of fetal blood circulation before a baby is born. The pulmonary artery carries blood from the heart to the lungs. The aorta carries blood from the heart to the body. The PDA lets oxygen-rich blood (blood high in oxygen) from the aorta mix with oxygen-poor blood (blood low in oxygen) in the pulmonary artery. As a result, too much blood flows into the lungs, which puts a strain on the heart and increases blood pressure in the pulmonary arteries.

PDA) The PDA is present in all babies before birth. It is an opening, which connects the AORTA (AO) (main blood vessel to the body) and the PULMONARY ARTERY (PA) (main blood vessel to the lungs) Why does a baby have a PDA?

Before birth, the baby does not need to use its lungs. However, when the baby is born, the blood must receive oxygen in the lungs and this hole is supposed to close. If the ductus arteriosus is still open (or patent ) the blood may skip this necessary step of circulation.

The open hole is called the patent ductus arteriosus. Mezu-Ndubuisi,Ghanshyam Agarwal,Aarti Raghavan,Jennifer T. Patent Ductus Arteriosus in Premature Neonates Olachi J.
