Purpose: The purpose of this study was to review the pharmacokinetic profile of gentamicin among neonates with hypoxic ischemic encephalopathy (HIE) undergoing therapeutic hypothermia (TH) treatment.

Methods: This was a retrospective study of neonates with HIE undergoing TH in the neonatal intensive care unit who received gentamicin between 2009 and 2014. Demographic information, diagnoses, laboratory test results, and medication administration and monitoring information were collected, and data were analyzed using SciPy.

Background And Objectives: Packed red blood cell transfusions (pRBCT) in preterm infants have been associated with significant morbidity. Although infants <26 weeks' gestational age typically require several pRBCT, preterm infants born between 26 and 34 weeks' gestational age may also require pRBCT during their hospitalization that are potentially preventable. We aimed to reduce pRBCT in this population by 20%.

Supportive care with mechanical ventilation continues to be an essential strategy for managing severe neonatal respiratory failure; however, it is well known to cause and accentuate neonatal lung injury. The pathogenesis of ventilator-induced lung injury (VILI) is multifactorial and complex, resulting predominantly from interactions between ventilator-related factors and patient-related factors. Importantly, VILI is a significant risk factor for developing bronchopulmonary dysplasia (BPD), the most common chronic respiratory morbidity of preterm infants that lacks specific therapies, causes life-long morbidities, and imposes psychosocial and economic burdens.

This study developed and validated a trace-level quantification inorganic impurities method using reversed-phase HPLC and performed the robustness check using quality-by-design approach by varying the multiple factors simultaneously. This method is economical and simple and exhibits its stability-indicating nature [for the determination of ferrocyanide ([Fe(CN)₆] ), ferricyanide ([Fe(CN) ] ), nitrate (NO ), and nitrite (NO )] in sodium nitroprusside (SNP) drug substance and liquid dosage form. Chromatographic separation was achieved using a USP L43 column (ACE PFP, 150 × 4.

A simple and isocratic reverse-phase liquid chromatography with mass spectrometric method has been developed and validated for the determination of heptaethylene glycol monomethyl ether in benzonatate drug substance. Benzonatate is an oral antitussive drug used to relieve and suppress cough in patients older than 10 years. The presence of residual heptaethylene glycol monomethyl ether in the benzonatate drug substance affects the safety, strength, purity and quality of the drug substance.

A simple reverse phase liquid chromatographic gradient method has been developed and validated for the simultaneous determination of specified & un-specified impurities of Telmisartan and Hydrochlorothiazide in combination oral solid dosage forms. The developed method is effective to separate a total of sixteen (16) peaks and quantify eleven (11) specified impurities of Telmisartan and three (3) specified impurities of Hydrochlorothiazide with a minimum chromatographic resolution of 2.5.

Nasal continuous positive airway pressure (NCPAP) is an effective method of respiratory support for preterm infants. Nasal masks and binasal prongs are two interfaces available to deliver NCPAP, and it is unclear if one is superior to the other. We conducted a systematic review and meta-analysis, using the methodology recommended by the Cochrane Collaboration, to compare the efficacy and safety of nasal masks versus binasal prongs to deliver NCPAP in preterm infants <37 weeks of gestation.

Objective: To evaluate the association between hypercarbia in the first 24 h of life and clinical outcomes in infants with congenital diaphragmatic hernia (CDH).

Study Design: Retrospective review of patients entered into the CDHSG registry between 2007-2014. Half of the identified patients were analyzed to identify the PaCO2 value most predictive of mortality.

An important step on the roadmap to a successful quality improvement (QI) project is careful selection of topics and aims to be addressed by QI projects. Using information from a variety of data monitoring systems as well as individual events and experiences, leaders of neonatal units and QI teams should first identify quality and safety gaps in their unit. They should then use an explicit, formal process for selecting the best projects to which their limited time and resources should be allocated.

Background: Neonatal endotracheal intubation is a life-saving procedural skill where best practices have been developed from expert opinion. Few empirical studies have examined how this skill should be taught.

Objective: To determine whether a video laryngoscope (VL) assisted intubation training curriculum compared to a traditional direct laryngoscope (DL) assisted curriculum improves neonatal intubation performance of novice intubators in a simulated setting.

Background And Objectives: Pediatric residency training programs are graduating residents who are not competent in neonatal intubation, a vital skill needed for any pediatrician involved in delivery room resuscitations. However, a precise definition of competency during training is lacking. The objective of this study was to more precisely define the trajectory toward competency in neonatal intubation for pediatric residents, as a framework for later evaluating complementary training tools.

Objectives: To identify teamwork behaviors associated with improving efficiency and quality of simulated resuscitation training.

Methods: Secondary analysis of a randomized controlled trial of trainees undergoing neonatal resuscitation training was performed. Trainees at a large academic center (n = 100) were randomized to receive standard curriculum (n = 36) versus supplemental team training curriculum (n = 62).

Background: Patent ductus arteriosus is a common occurrence among prematurely born neonates and is believed to play a role in the development of other complications of prematurity including intraventricular hemorrhage, bronchopulmonary dysplasia, and necrotizing enterocolitis. The clinical decision to treat the patent ductus arteriosus is complicated by the lack of evidence available regarding clinical conditions under which closure should be attempted.

Study Aims: To compare clinical outcomes for neonates who underwent treatment of patent ductus arteriosus exhibiting bidirectional blood flow versus those with flow that was left to right.

We compared the rates of medical closure of patent ductus arteriosus (PDA) and complications (renal dysfunction, necrotizing enterocolitis, spontaneous intestinal perforation, and intraventricular hemorrhage) between infants treated with indomethacin and infants treated with ibuprofen. We performed a retrospective comparative cohort study of infants treated with indomethacin or ibuprofen for symptomatic PDA at Duke University Medical Center between November 2005 and November 2007. We identified 65 infants who received indomethacin and 57 who received ibuprofen.
