TLDR
The use of high-dose milrinone after pediatric congenital heart surgery reduces the risk of low cardiac output syndrome (LCOS), a contributes to postoperative morbidity and mortality.
Abstract
Background— Low cardiac output syndrome (LCOS), affecting up to 25% of neonates and young children after cardiac surgery, contributes to postoperative morbidity and mortality. This study evaluated the efficacy and safety of prophylactic milrinone in pediatric patients at high risk for developing LCOS. Methods and Results— The study was a double-blind, placebo-controlled trial with 3 parallel groups (low dose, 25-μg/kg bolus over 60 minutes followed by a 0.25-μg/kg per min infusion for 35 hours; high dose, 75-μg/kg bolus followed by a 0.75-μg/kg per min infusion for 35 hours; or placebo). The composite end point of death or the development of LCOS was evaluated at 36 hours and up to 30 days after randomization. Among 238 treated patients, 25.9%, 17.5%, and 11.7% in the placebo, low-dose milrinone, and high-dose milrinone groups, respectively, developed LCOS in the first 36 hours after surgery. High-dose milrinone significantly reduced the risk the development of LCOS compared with placebo, with a relative ...

Vasoactive-inotropic score as a predictor of morbidity and mortality in infants after cardiopulmonary bypass

TL;DR: The usefulness of vasoactive–inotropic score as an independent predictor of clinical outcome in infants after cardiac surgery may have important implications for future cardiothoracic intensive care unit research.

Pediatric Basic Life Support: 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care

TL;DR: For best survival and quality of life, pediatric basic life support should be part of a community effort that includes prevention, early cardiopulmonary resuscitation (CPR), prompt access to the emergency response system, and rapid pediatric advanced life support (PALS), followed by integrated post–cardiac arrest care.

Postoperative Course and Hemodynamic Profile After the Arterial Switch Operation in Neonates and Infants A Comparison of Low-Flow Cardiopulmonary Bypass and Circulatory Arrest

TL;DR: After heart surgery in neonates and infants, both low-flow bypass and circulatory arrest perfusion strategies have comparable effects on the nonneurological postoperative course and hemodynamic profile.

Perioperative effects of alpha-stat versus ph-stat strategies for deep hypothermic cardiopulmonary bypass in infants ☆ ☆☆ ★ ★★ ♢

TL;DR: Use of the pH-stat strategy in infants undergoing deep hypothermic cardiopulmonary bypass was associated with lower postoperative morbidity, shorter recovery time to first electroencephalographic activity, and, in patients with D-transposition, shorter duration of intubation and intensive care unit stay.

Milrinone: Systemic and pulmonary hemodynamic effects in neonates after cardiac surgery

TL;DR: Administration of milrinone in neonates with low cardiac output after cardiac surgery lowers filling pressures, systemic and pulmonary arterial pressures, and systemic andmonary vascular resistances, while improving cardiac index.

Cardiac performance and mortality early after intracardiac surgery in infants and young children.

TL;DR: It is concluded that in such patients treatment should be directed toward keeping CI greater than 2.0 l-min minus 1-m minus 2 and P-vO2 greater than 30 mm Hg and that a therapeutic trial of reducing left ventricular afterload is indicated in some of these patients.
