We also sought to determine the optimal time at which the VVR score should be measured.

Methods: We retrospectively reviewed neonates recovering from cardiac surgery between July 2017 and June 2020.

Ninety-two days of extracorporeal membrane oxygenation support following congenital heart surgery.

We report on a case involving a 10-month-old infant who received prolonged ECMO therapy following cardiac surgery for multiple ventricular septal defects (VSD). The patient was successfully weaned from 92 days of ECMO support without any long-term deficits.

Bedside PDA ligation in premature infants less than 28 weeks and 1000 grams.

Background: PDA(Patent ductus arteriosus) is a common and clinically important condition which is presented with a number of hemodynamic and respiratory problems such as intraventricular hemorrhage, pulmonary hemorrhage and necrotizing enterocolitis due to increased pulmonary blood flow and stealing from systemic circulation. The incidence of PDA among the infants that were born before the 28th gestational week is as high as 70 %; and spontaneous closure rates in very-low-birth-weight premature neonates(VLBWPN) is around 34 %. The onset, duration, and repeat number of consecutive courses of the prostaglandin synthesis inhibitor medication for PDA closure are still issues of debate.
