Caffeine and Less Invasive Surfactant Administration for Respiratory Distress Syndrome of the Newborn.

Caffeine and Less Invasive Surfactant Administration for RDSPreterm infants with respiratory distress syndrome may benefit from the use of less invasive surfactant administration or continuous positive airway pressure to avoid intubation. The authors compare the two methods, with the additional use of caffeine in both groups.

The Term Newborn: Evaluation for Hypoxic-Ischemic Encephalopathy.

Neonatal encephalopathy due to perinatal hypoxia-ischemia (hypoxic-ischemic encephalopathy [HIE]) occurs at a rate of 1 to 3 per 1000 live births. Therapeutic hypothermia is the standard of care and the only currently available therapy to reduce the risk of death or disability in newborns with moderate to severe HIE. Hypothermia therapy needs to be initiated within 6 hours after birth in order to provide the best chance for neuroprotection. All pediatricians and delivery room attendants should be trained to recognize encephalopathy and understand the eligibility criteria for treatment. The modified Sarnat examination is the most frequently used tool to assess the degree of encephalopathy and has six categories, each of which can have mild, moderate, severe abnormalities. Apart from historical and biochemical criteria, a neonate must have 3 of 6 categories scored in the moderate or severe range in order to qualify for hypothermia as was done in the randomized trials. Whether an infant qualifies or there is concern that an infant might have HIE, transfer to a center that can perform treatment should be initiated immediately. Hypothermia significantly reduces the risk of death or moderate to severe impairments at 2 years and at school age. On average, only 7 neonates need to be treated for one neonate to benefit. Although easy in concept, implementation of hypothermia does require expertise and should be carried out under the guidance of a neonatologist. If infants are passively cooled prior to transport, core temperature needs to be closely monitored with a target of 33.5°C ± 0.5°C. Maintenance of homeostasis is important in order to prevent conditions that may result in additional brain injury. Seizures are common in neonates with HIE, but electrographic seizures are rare in the first few hours after birth if the insult occurred during labor and delivery. Prophylactic antiepileptic drugs should not be administered. Brain monitoring in the form of electroencephalogram (EEG) and or amplitude-integrated EEG should be implemented as soon as possible to help with prognosis and to accurately diagnose seizures.

Lessons Learned from a Collaborative to Develop a Sustainable Simulation-Based Training Program in Neonatal Resuscitation: Simulating Success.

Newborn resuscitation requires a multidisciplinary team effort to deliver safe, effective and efficient care. California Perinatal Quality Care Collaborative's Simulating Success program was designed to help hospitals implement on-site simulation-based neonatal resuscitation training programs. Partnering with the Center for Advanced Pediatric and Perinatal Education at Stanford, Simulating Success engaged hospitals over a 15 month period, including three months of preparatory training and 12 months of implementation. The experience of the first cohort (Children's Hospital of Orange County (CHOC), Sharp Mary Birch Hospital for Women and Newborns (SMB) and Valley Children's Hospital (VCH)), with their site-specific needs and aims, showed that a multidisciplinary approach with a sound understanding of simulation methodology can lead to a dynamic simulation program. All sites increased staff participation. CHOC reduced latent safety threats measured during team exercises from 4.5 to two per simulation while improving debriefing skills. SMB achieved 100% staff participation by identifying unit-specific hurdles within in situ simulation. VCH improved staff confidence level in responding to neonatal codes and proved feasibility of expanding simulation across their hospital system. A multidisciplinary approach to quality improvement in neonatal resuscitation fosters engagement, enables focus on patient safety rather than individual performance, and leads to identification of system issues.

Multicentre, randomised trial of preterm infants receiving caffeine and less invasive surfactant administration compared with caffeine and early continuous positive airway pressure (CaLI trial): study protocol.

INTRODUCTION: Respiratory distress syndrome (RDS) or surfactant deficiency occurs primarily in premature infants resulting in composite outcomes of death or bronchopulmonary dysplasia. Initial management strategies for preterm infants with RDS includes early initiation of continuous positive airway pressure (CPAP) and titration of fractional inspired oxygen (FiO2), and may include the use of less invasive surfactant administration (LISA) to avoid the need for mechanical ventilation. In order to optimise success of non-invasive support, the use of early caffeine therapy may be critical to the success of LISA. The objective of our trial is to evaluate whether infants that receive early caffeine, CPAP and surfactant via the LISA method compared with infants that receive caffeine and CPAP alone, have a decreased need for invasive mechanical ventilation in the first 72 hours of life. METHODS AND ANALYSIS: CaLI is an unblinded multicentre, randomised controlled, trial of 180 preterm infants (24+0-29+6 weeks corrected GA). Criteria for intubation/treatment failure will follow guidelines for the management of RDS, including: (1) CPAP level of 6-8 cmH20 and FiO2 >0.40 required to maintain saturations 90%-95% for 2 hours after randomisation; (2) a pH of 7.15 or less or a paCO2 >65 mm Hg on any (2) blood gases (arterial/capillary/or venous) at least 2 hours after randomisation and in the first 72 hours of life; (3) continued apnoea/bradycardia/desaturation events despite nasal intermittent minute ventilation mode of ventilation. Infants will be randomised by 1 hour of life and caffeine/LISA treatments administered by 2 hour of life. Caffeine will be administered prior to surfactant in the LISA arm and before 2 hours of life in the control arm. ETHICS AND DISSEMINATION: Chiesi Farmaceutici, S.p.A is the sponsor of CaLI. Ethical approval has been obtained. Results will be submitted for publication in peer reviewed journals. TRIAL REGISTRATION NUMBER: www.Clinicaltrials.gov: NCT04209946; Pre-results.

High Prevalence of Pulmonary Hypertension Complicates the Care of Infants with Omphalocele.

BACKGROUND: Omphalocele is one of the most common abdominal wall defects. Many newborn infants born with omphalocele present with significant respiratory distress at birth, requiring mechanical ventilatory support, and have clinical evidence of pulmonary hypertension. Little information exists on the prevalence of and risk factors associated with pulmonary hypertension in this cohort of infants. OBJECTIVES: To describe the prevalence of and risk factors associated with pulmonary hypertension among infants with omphalocele. METHODS: This is a multicenter retrospective chart review of demographic data and clinical characteristics of infants with omphalocele admitted to the neonatal intensive care units of Loma Linda University Children's Hospital and Children's Mercy Hospital between 1994 and 2011. Echocardiogram images were reviewed for pulmonary hypertension, and statistical analyses were performed to identify risk factors associated with the presence of pulmonary hypertension. RESULTS: Pulmonary hypertension was diagnosed in 32/56 (57%) infants with omphalocele. Compared to infants without pulmonary hypertension, infants with pulmonary hypertension were more likely to have a liver-containing defect (16/32 [50%] vs. 5/24 [21%], p = 0.03), require intubation at birth (18/32 [56%] vs. 6/24 [17%], p = 0.03), and die during initial hospitalization (12/32 [38%] vs. 2/24 [8%], p = 0.01). CONCLUSION: The majority of infants with omphalocele have evidence of pulmonary hypertension which is associated with increased mortality. Echocardiograms to screen for pulmonary hypertension should be obtained at ≥2 days of life in infants with omphalocele, especially in those with liver within the omphalocele sac and/or in those infants who require intubation at birth to screen for pulmonary hypertension.

Early Blood Transfusion and Resolution of Disseminated Intravascular Coagulation Associated with Massive Subgaleal Hemorrhage.

A male infant delivered to a primipara woman following vacuum applications. He was vigorous at birth, with small caput and scalp bruising. His head was enlarging; he became pale with respiratory distress. Subgaleal hemorrhage (SGH) was suspected. His hematocrit was noted to be 26.2 percent prior to transfusion of O, Rh-negative blood (40 mL/kg). Moderate disseminated intravascular coagulation (DIC) was noted at 12 hours of age. Posttransfusion of fresh frozen plasma (FFP), his condition became stable, and DIC gradually resolved. Head magnetic resonance imaging did not show intracranial hemorrhage. Although one episode of seizures was noted, electroencephalogram was normal. With the application of obstetric vacuum, we recommend that the neonatal health care professionals frequently evaluate the infant's condition. In light of developing fluctuant subgaleal fluid associated with pallor, anemia, metabolic acidosis, and respiratory distress, immediate blood transfusion is warranted. In the presence of DIC, transfusion of FFP is beneficial.

Nitrate reductase activity of bacteria in saliva of term and preterm infants.

The salivary glands of adults concentrate nitrate from plasma into saliva where it is converted to nitrite by bacterial nitrate reductases. Nitrite can play a beneficial role in adult gastrointestinal and cardiovascular physiology. When nitrite is swallowed, some of it is converted to nitric oxide (NO) in the stomach and may then exert protective effects in the gastrointestinal tract and throughout the body. It has yet to be determined either when newborn infants acquire oral nitrate reducing bacteria or what the effects of antimicrobial therapy or premature birth may be on the bacterial processing of nitrate to nitrite. We measured nitrate and nitrite levels in the saliva of adults and both preterm and term human infants in the early weeks of life. We also measured oral bacterial reductase activity in the saliva of both infants and adults, and characterized the species of nitrate reducing bacteria present. Oral bacterial conversion of nitrate to nitrite in infants was either undetectable or markedly lower than the conversion rates of adults. No measurable reductase activity was found in infants within the first two weeks of life, despite the presence of oral nitrate reducing bacteria such as Actinomyces odontolyticus, Veillonella atypica, and Rothia mucilaginosa. We conclude that relatively little nitrite reaches the infant gastrointestinal tract due to the lack of oral bacterial nitrate reductase activity. Given the importance of the nitrate-nitrite-NO axis in adults, the lack of oral nitrate-reducing bacteria in infants may be relevant to the vulnerability of newborns to hypoxic stress and gastrointestinal tract pathologies.
