In recent years, there have been significant advancements in our understanding of acute kidney injury (AKI) and its impact on outcomes across medicine. Research based on single-center cohorts suggests that neonatal AKI is very common and associated with poor outcomes. In this state-of-the-art review on neonatal AKI, we highlight the unique aspects of(More)
Airway pressure release ventilation (APRV) allows ventilation and oxygenation to occur at lower peak and mean airway pressures than conventional positive pressure ventilation. The use of APRV in adults is an effective method of ventilation for patients with acute lung injury and acute respiratory distress syndrome. However, the use of APRV in children is(More)
Bronchodilators have been used in premature infants. Levalbuterol (LEV) an R-isomer of Albuterol has fewer hemodynamic side effects than Racemic Albuterol (RAC) in adults and children. In a retrospective study we sought to investigate the effects of LEV (0.31 mg) versus RAC (1.25 mg) in very low-birth weight infants (VLBW) who were treated with a beta-2(More)
BACKGROUND Racemic (R,R/S,S)-formoterol is a long-acting β-agonist composed of a 50:50 mixture of (R,R)- and (S,S)-enantiomers. OBJECTIVE The aim of this study was to determine whether (R,R)-formoterol and (R,R/S,S)-formoterol have differing effects on airway contraction and relaxation in vitro. METHODS Cylindrical airway segments 3-mm long were(More)
The aim of this study was to determine the incidence, risk factors, and outcome of acute kidney injury (AKI) in extremely low birth weight (ELBW) infants. In a case–control study, medical records of all ELBW infants who were admitted to our Neonatal Intensive Care Unit (NICU) between 1 January 2000 and 31 January 2008 were reviewed. During the study period,(More)
OBJECTIVES Little is known about the relationship between gestational age (GA) or birth weight (BW) and serum creatinine (SCr) in very low birth weight (VLBW) infants. We sought to study postnatal SCr changes and determine if there is a correlation between GA or BW and SCr in VLBW infants, during their first days of life. STUDY DESIGN Medical records of(More)
OBJECTIVE Increased intrathoracic pressures during airway pressure release ventilation (APRV) may compromise systemic venous return resulting in decreased cardiac output and renal perfusion. We sought to study the short-term effect of APRV on blood pressure (BP) and urine output (UO) in children with acute lung injury (ALI) or acute respiratory distress(More)
The aim of this retrospective, case–control study was to determine the effect of the amphotericin B lipid complex (ABLC) on serum creatinine (SCr), blood urea nitrogen (BUN), sodium (Na), and potassium (K) in very low birth weight (VLBW) infants. Medical records of all VLBW infants who were admitted to our Neonatal Intensive Care Unit between May 1998 and(More)
