These data may be questionable, because surgical ligation is not available in every nursery, whereas medical therapy is widely available. Patent ductus arteriosus PDA affects approximately 31% of infants whose birth weight is between 501 and 1500 g.

Patent Ductus Arteriosus (PDA) Treatment & Management

Hi, I saw this question and normally I thought we would want to keep it open with prostaglandins if it is not causing cyanosis? I thought in general it is vital to keep it open so long as it is not becoming left to right? Doesn't to keeping it open result in more pulmonary blood flow? I totally suck at the physiology of this and DIT did not do a good job at explaining it either. I thought in general it is vital to keep it open so long as it is not becoming left to right?

It's not supposed to be open, so we close it. BTW, it is a LTR shunt... Let's just fix it now. If PGE keeps it open, then we use indomethacin NSAID to decrease PG synthesis and close it.

Thanks, i see PDA being a right to left shunt.... Eventually the blood will back flow and you get the cyanosis? I understand what you are saying with the transpositon of vessels though.

PDA is obviously Left to right due to the lung + placental changes at birth. And how did you not learn that treatment is ligating it right away...? The shunt can get bigger with age. And even if it is getting more oxygen, what about cardiac reserve? Thanks, i see PDA being a right to left shunt.... Eventually the blood will back flow and you get the cyanosis? I understand what you are saying with the transpositon of vessels though. Well someone can clarify if I'm wrong. Otherwise I may be confusing myself too. Rule of thumb: flow will go down a pressure gradient. In utero, it is a RtL shunt. This is because the fetus has no use for lungs and with hypoxia the lung vasculature will vasoconstrict. Now LtR shunt is normally not cyanotic. But if there is too much blood in the pulmonary vessels, over time it will again become a high pressure circuit I believe via hyaline arteriolosclerosis , and flow will go back to being RtL. The rest of the body becomes cyanotic. Well someone can clarify if I'm wrong. Otherwise I may be confusing myself too. Rule of thumb: flow will go down a pressure gradient.

I don't think it hyaline arteriosclerosis HA that you get with higher pressures in the pda but just your run of the mill medial hypertrophy due to the higher pressures on the vessel smooth muscle. You typically onky get HA with very small vessels. I may be wrong but it sounds right in my head lol. Well someone can clarify if I'm wrong. Otherwise I may be confusing myself too.

The rest of the body becomes cyanotic. The drug is prime for use in the neonate with ductal-dependent pulmonary blood flow, including: pulmonary atresia, tricuspid atresia, Tetralogy of Fallot, and will often improve systemic oxygen saturation in infants with transposition of the how does prostaglandins keep pda open vessels. A large PDA that offers no resistance of its own non-restrictive may result in a considerable increase in glad blood flow eventually leading to high output heart failure despite improved ventricular performance due to decreased afterload. DOSING AND ADMINISTRATION The regimen for treatment of PDA with ibuprofen comprises three doses. Transcatheter closure of patent ductus arteriosus: experience with a new device. Cochrane Database Syst Rev. And even if it is for more oxygen, what about cardiac reserve. It conceivably results from abnormal elastin formation or abnormal intimal cushion formation. Rule of thumb: flow will go down a pressure gradient. Blood enters the pulmonary circulation, which delivers prostaglandins to the lungs, where they are metabolized and met. The umbilical cord is simultaneously clamped separating the placenta from the systemic bed and the systemic vascular resistance quickly rises above that of the pulmonary bed.
