Objective: To evaluate a precise definition of a clinically significant cardiopulmonary event (CSCPE) on the hospital length of stay (LOS), medical provider satisfaction, and discharge complications.

Study Design: This is a single-center, observational study that included 139 infants before and 134 infants after the new definition was implemented in December 2017. Retrospective data collected November 2015 to November 2017 (before) was compared with prospective data from June 2018 to July 2020 (after).

 Reduce the number of infants requiring home tube feeds by initiating an oral feeding protocol (OFP).  All infants < 30 weeks' gestation were eligible. The OFP involved four steps: encourage non-nutritive suck before 30 weeks, oral motor exercises starting as early as 30 weeks, swallowing exercises as early as 31 weeks, and an infant-driven oral feeding pathway as early as 32 weeks.

Background And Objectives: Infant mortality is an indicator of overall societal health, and a significant proportion of infant deaths occur in NICUs. The objectives were to identify causes of death and to define potentially preventable factors associated with death as areas for quality improvement efforts in the NICU.

Methods: In a prospectively defined study, the principal investigator in 46 level III NICUs agreed to review health care records of infants who died.

Objective: To determine the bacterial contamination rate of the parent's cell phone and the effectiveness of anti-microbial gel in reducing transmission of bacteria from cell phone to hands.

Methods: Cross-sectional study of cultures from the cell phone and hands before and after applying anti-microbial gel (n=50).

Results: All cell phones demonstrated bacterial contamination.

Two cases are described in which a peripherally inserted central catheter tip in the saphenous vein appeared to be in the inferior vena cava by an anteroposterior abdominal radiograph, but a lateral view revealed the catheter tip to be outside the inferior vena cava. The actual location of the catheter tip placement may be misleading with a single radiograph. Two-view radiographs should be considered to assure the proper catheter tip placement.

Objective: To evaluate the incidence of necrotizing enterocolitis (NEC) after implementing standardized feeding schedules.

Method: This was a cohort study, which retrospectively reviewed the incidence of NEC for a 3-year period before implementing feeding schedules and prospectively evaluated the incidence of NEC for a 3-year period after implementing feeding schedules in infants with birth weights between 1250 and 2500 g and <35 weeks' gestation. The feeding schedules were comprised of 3 parts.

We have previously reported a case study in which renal calcification formation may have been a complication of dexamethasone exposure in an infant with bronchopulmonary dsyplasia. To determine whether dexamethasone is associated with renal calcification formation, we conducted a prospective, nonrandomized study of 36 infants < 30 weeks' gestation and weighing < 1250 gm treated with dexamethasone because of bronchopulmonary dysplasia and compared them with a group not receiving dexamethasone. We identified seven infants in the dexamethasone group (n = 19) but no infant in the comparison group (n = 17) with renal calcifications at 2 months of age (p = 0.

We studied healthy and saline lavaged rabbits during high frequency oscillatory ventilation to determine what combination of frequency (f), tidal volume (Vt), and mean airway pressure (Paw) produced the lowest peak-to-peak alveolar pressure amplitude (Palv) and physiologic blood gas tensions. Sinusoidal volume changes were delivered through a tracheostomy by a piston pump driven by a linear motor. Tracheal pressure amplitude (Ptr) was measured through a tracheal catheter and alveolar pressure amplitude was measured in a capsule glued to the right lower lobe.

The circumstances and characteristics of emergency room-treated injuries in children younger than 1 year of age were studied and unintentional injuries were compared with those caused by abuse. Unintentional injuries were seen 15 times more frequently in an emergency room than injuries caused by abuse. The majority of unintentional injuries were minor, although skull fractures and fractures of the clavicle did occur.
