oxygen AND neonatology

Rene Gumulak, Lucia Casnocha Lucanova, Mirko Zibolen
Near-infrared spectroscopy (NIRS) is a technology capable of non-invasive, continuous measuring of regional tissue oxygen saturation (StO2). StO2 represents a state of hemodynamic stability, which is influenced by many factors. Extensive research has been done in the field of measuring StO2 of various organs. The current clinical availability of several NIRS-based devices reflects an important development in prevention, detection and correction of discrepancy in oxygen delivery to the brain and vital organs...

Retinopathy of Prematurity (ROP) is a retinal vascular disease of the premature infant. There have been significant advances in the understanding of the pathogenesis, prevention, detection and treatment of severe ROP. In developed countries, all premature infants at risk for ROP are screened routinely based on national guidelines and treatment is prompt, resulting in good visual outcomes. Blindness from ROP is a rare event in these countries. However, there is an ongoing epidemic of ROP- induced blindness in India...

Vital parameter monitoring of term and preterm infants during incubator care with self-adhesive electrodes or sensors directly positioned on the skin [e.g. photoplethysmography (PPG) for oxygen saturation or electrocardiography (ECG)] is an essential part of daily routine care in neonatal intensive care units. For various reasons, this kind of monitoring contains a lot of stress for the infants. Therefore, there is a need to measure vital parameters (for instance respiration, temperature, pulse, oxygen saturation) without mechanical or conductive contact...

BACKGROUND: Perfusion index (PI) is becoming a part of clinical practice in neonatology to monitor peripheral perfusion noninvasively. Hemodynamic and respiratory changes occur in newborns during the transition period after birth in which peripheral perfusion may be affected. Tachypnea is a frequent symptom during this period. While some tachypneic newborns get well in less than 6 h and diagnosed as "delayed transition", others get admitted to intensive care unit which transient tachypnea of newborn (TTN) being the most common diagnosis among them...

Despite the many advances in neonatology, bronchopulmonary dysplasia (BPD) continues to be a frustrating disease of prematurity. BPD is a disease which is defined oddly by its treatment rather than its pathophysiology, leading to frequently changing nomenclature which has widespread implications on our ability to both understand and follow the progression of BPD. As various treatment modalities for BPD were developed and a larger number of extremely preterm infants survived, the "old" BPD based on lung injury from oxygen therapy and mechanical ventilation transitioned into a "new" BPD focused more on the interruption of normal development...

In neonatology, blood gas analysis is a useful tool in the evaluation of the health of newborns and plays a key role in early detection of critically ill subjects. Because blood gas analysis parameters have not previously been studied in any depth in donkey foals, this study was performed on 16 healthy Martina Franca donkey foals born after an uncomplicated delivery. Arterial and venous blood samples were collected at 5 minutes and at 12, 24, 72, and 96 hours of age. Blood gas analysis was performed by a portable analyzer, measuring arterial and venous total carbon dioxide, carbon dioxide partial pressure (pCO2), oxygen partial pressure (pO2), oxygen saturation (sO2), bicarbonate, base excess (BE), pH, and lactate (LT)...

BACKGROUND: The International Liaison Committee on Resuscitation (ILCOR) published Consensus 2015 in October 2015. Thereafter, the Japanese version of neonatal cardiopulmonary resuscitation programs was revised. Prior to the revision, we re-conducted questionnaire surveys in three types of medical facilities in January 2015. METHODS: Targeted groups included (i) 277 training hospitals authorized by the Japanese Society of Perinatal/Neonatal Medicine for training of physicians specialized in perinatal care (neonatology) in January 2015 (training hospitals; response rate, 70...

Our preliminary data show high levels of adenosine in the blood of very low birth weight (VLBW) infants, positively correlating to their prematurity (i.e. body weight class). This prompted us to look for a mechanism promoting such impressive adenosine increase. We hypothesized a correlation with oxygen challenge. In fact, it is recognized that either oxygen lack or its excess contribute to the pathogenesis of the injuries of prematurity, such as retinopathy (ROP) and periventricular white matter lesions (PWMI)...

Over the last 5 years, there has been a dramatic increase in the use of extracorporeal membrane oxygenation (ECMO) in adult patients with severe respiratory or cardiac failure. This contrasts to the use of the technology in neonatal and paediatric intensive care units, where it has been regarded as a standard of care for a number of conditions for over 25 years. Many innovations in ECMO circuitry or clinical management evolve first in one particular discipline and it may be helpful for individual clinicians to keep abreast of developments in ECMO across the entire age range, from neonatology to older adults...

Newborn respiratory distress presents a diagnostic and management challenge. Newborns with respiratory distress commonly exhibit tachypnea with a respiratory rate of more than 60 respirations per minute. They may present with grunting, retractions, nasal flaring, and cyanosis. Common causes include transient tachypnea of the newborn, respiratory distress syndrome, meconium aspiration syndrome, pneumonia, sepsis, pneumothorax, persistent pulmonary hypertension of the newborn, and delayed transition. Congenital heart defects, airway malformations, and inborn errors of metabolism are less common etiologies...

Proteomics is the global study of proteins in an organism or a tissue/fluid and is clinically relevant since most disease states are accompanied by specific alterations in an organism's proteome. This review focuses on the application of proteomics to neonatology with particular emphasis on retinopathy of prematurity (ROP), which is a disease in which oxidative stress plays a key pathophysiological role. Oxidative stress is a physiologically relevant redox imbalance caused by an excess of reactive oxygen (ROS) or reactive nitrogen oxide species (RNOS)...

OBJECTIVE: High flow nasal cannula therapy (HFT) has been shown to be similar to nasal continuous positive airway pressure (nCPAP) in neonates with respect to avoiding intubation. The objective of the current study is to determine if there are trends for adverse safety and long-term respiratory outcomes in very low birth weight infants (<1500 g) from centers using HFT as their primary mode of non-invasive respiratory support compared to data from the largest neonatal outcomes database (Vermont Oxford Network; VON)...

The survival of preterm babies has increased over the last few decades. However, disorders associated with preterm birth, known as oxygen radical diseases of neonatology, such as retinopathy, bronchopulmonary dysplasia, periventricular leukomalacia, and necrotizing enterocolitis are severe complications related to oxidative stress, which can be defined by an imbalance between oxidative reactive species production and antioxidant defenses. Oxidative stress causes lipid, protein, and DNA damage. Preterm infants have decreased antioxidant defenses in response to oxidative challenges, because the physiologic increase of antioxidant capacity occurs at the end of gestation in preparation for the transition to extrauterine life...

In this article we evaluated the consistency of practice and the adherence to the International Guidelines in early delivery room management of ELBW infants in Italy. A polyethylene bag/wrap was used by 54 centres (55.1%). In Northern regions, one centre (2.5%) reported to use oxygen concentrations >40% to initiate positive pressure ventilation in ELBW infants. These proportions were higher in the Central (14.3%) and Southern (16.2%) areas. A T-piece device for positive pressure ventilation was widely used (77/97, 79...

OBJECTIVE: Extremely preterm (EP) and extremely low birth weight infants (ELBWI) tended to suffer from some serious complications. How to treat and make them survive reflect the progress of perinatal medicine and neonatal treatment technology. But in our country, there was still lack of data analysis about the morbidities and interventions of large sample survey on such infants. This study was designed to survey the in-hospital morbidities of EP and ELBWI who had been admitted to neonatology departments...

BACKGROUND: Ketamine, a noncompetitive N-Methyl-D-aspartate (NMDA) receptor antagonist, is a commonly used dissociative anesthetic in neonatology. We have proposed that ketamine reduces fetal stress responsiveness to stimuli that involve reduced oxygen supply to the fetal brain. Previously, we have shown that ketamine inhibits plasma ACTH levels in late-gestation fetal sheep subjected to brachiocephalic artery occlusion (BCO), an ischemic hypoxia model that might activate some of the same direct and reflex responses as hypoxia...

High-flow nasal cannula (HFNC) is a relatively new device for respiratory support. In pediatrics, HFNC use continues to increase as the system is easily set up and is well tolerated by patients. The use of nasal cannula adapted to the infant's nares size to deliver heated and humidified gas at high flow rates has been associated with improvements in washout of nasopharyngeal dead space, lung mucociliary clearance, and oxygen delivery compared with other oxygen delivery systems. HFNC may also create positive pharyngeal pressure to reduce the work of breathing, which positions the device midway between classical oxygen delivery systems, like the high-concentration face mask and continuous positive airway pressure (CPAP) generators...

Pulmonary hypertension of the newborn is a clinical syndrome with diverse etiology in which the transition from fetal circulation with high pulmonary vascular resistance to postnatal circulation with low pulmonary vascular resistance failed. The persistence of high pulmonary vascular pressure leads to right-left shunts and marked cyanosis. Despite of the advances in neonatology, the treatment of some forms of PPHN is often difficult and mortality rate remains high. In infants with PPHN appropriate interventions are critical to reverse hypoxemia, improve pulmonary and systemic perfusion and preserve end-organ function...
