Department of Obstetrics and Gynaecology, Bayero University, Kano, Nigeria.

Background: Postdate pregnancy is a very common obstetric condition, increasing the risk of perinatal morbidity and mortality from uteroplacental insufficiency.

Aim: To determine the predictive values of Doppler cerebroplacental ratio (CPR), that is, the ratio between middle cerebral artery (MCA) and UA pulsatility indices (UA PI), and other potential velocimetric predictors of adverse perinatal outcomes in women with postdated pregnancies.

Patients And Methods: A prospective cohort study was conducted on consenting 212 low-risk pregnant women beyond 40 weeks' gestational age. Read More

Bedside lung ultrasound may be an effective method for the assessment of lung recruitment in newborns with extracorporeal membrane oxygenation (ECMO). We report a case of a neonate who had severe hypoxemia with persistent pulmonary hypertension and massive pneumothorax due to meconium aspiration syndrome and was treated with ECMO. Positive pressure mechanical ventilation resulted in persistent massive air leakage from the disrupted pulmonary tissue. Read More

Neonatal lung biopsy guides important medical decisions when the diagnosis is not clear from prior clinical assessment, imaging, or genetic testing. Common scenarios that lead to biopsy include severe acute respiratory distress in a term neonate, pulmonary hypertension disproportionate to that expected for gestational age or known cardiac anomalies, and assessment of suspected genetic disorder based on clinical features or genetic variant of unknown significance. The differential diagnosis includes genetic developmental disorders, genetic surfactant disorders, vascular disorders, acquired infection, and meconium aspiration. Read More

Extracorporeal membrane oxygenation (ECMO) is a complex life-saving support for acute cardio-respiratory failure, unresponsive to medical treatment. Starting a new ECMO program requires synergizing different aspects of organizational infrastructures and appropriate extensive training of core team members to deliver the care successfully and safely. To describe the process of establishing a new neonatal ECMO program and to evaluate the program by benchmarking the ECMO respiratory outcomes and mechanical complications to the well-established Extracorporeal Life Support Organization (ELSO) registry data.

Since March 2020, the world is involved in the COVID-19 pandemic, a disease caused by a novel virus called SARS-CoV-2. Some authors have described the ultrasonographic findings of COVID-19 pneumonia in adults and children, but data on neonates are lacking. Our objective was to describe the ultrasonographic lung pattern on newborns with SARS-CoV-2 infection during the COVID-19 pandemic. Read More

Thoracic ultrasound (TUS) is increasingly studied in neonatal respiratory distress but chest x-ray (CXR) remains the first-line exam. We aimed to evaluate its diagnostic performance for the investigation of unselected causes of neonatal respiratory distress in daily practice. We conducted a descriptive, prospective, and single-center diagnostic accuracy study in a tertiary hospital, including term and preterm newborns who needed a CXR because of respiratory conditions occurring at birth or during the first 24h of life.

Background: Transient tachypnea of the newborn (TTN) is one of the most common causes of neonatal respiratory distress (RD). However, distinguishing TTN from other causes of RD may be difficult during the first 12:24 h after birth. Lung ultrasonography (LUS) has been successfully utilized in the diagnosis and differential diagnosis of neonatal RD. Read More

Importance: Nasal continuous positive airway pressure (NCPAP) as a primary respiratory therapy in meconium aspiration syndrome (MAS) has not been studied extensively. Nasal continuous positive airway pressure, when applied in newborns with MAS, may resolve atelectasis by sufficiently expanding partially obstructed small airways and stabilizing the collapsing terminal airways to enhance oxygen exchange.

Objective: To compare NCPAP vs standard care in neonates with moderate to severe respiratory failure due to MAS in reducing the need for invasive ventilation. Read More

Aim: Neonatal hypoxic ischemic encephalopathy (HIE) patients are at times accompanied by persistent pulmonary hypertension (PPHN), which is by itself another risk factor of adverse outcomes. We aimed to assess the outcome of therapeutic hypothermia (TH) in these patients whom we managed to reverse the shunt flow, as they are expected to be at much higher risk of adverse neurodevelopmental outcome.

Methods: We reviewed the medical records of 116 HIE infants (13 with PPHN and 103 without PPHN) who underwent TH between 2012 and 2016. Read More

Lung ultrasound (LU) is becoming a bedside point-of-care technique in critical care and emergency medicine as it is performed and immediately interpreted by the clinician. LU is quick, easy, relatively inexpensive, and provides accurate diagnostic information when compared with conventional lung imaging methods, such as CT scans and chest radiographs, with the additional advantage of being non-irradiating, adapted to bedside use, and easily repeatable with no side effects for the patient. LU is easy to learn, does not require sophisticated ultrasound machines or settings, and shows low intra- and interobserver variability when a standardized approach is used. Read More

Division of Neonatology, Department of Pediatrics, University at Buffalo, Buffalo, N.Y., USA.

Background: The Neonatal Resuscitation Program (NRP) recommends close monitoring of oxygenation during the resuscitation of newborns using a pulse oximeter. However, there are no guidelines for monitoring carbon dioxide (CO2) to assess ventilation. Considering that cerebral blood flow (CBF) correlates directly with PaCO2, continuous capnography monitoring of end-tidal CO2 (ETCO2) may limit fluctuations in PaCO2 and, therefore, CBF during resuscitation of asphyxiated infants.

Background: Despite advances in diagnostic imaging and focused antenatal care, cases of undiagnosed abdominal pregnancies at term are still reported in obstetric practice. It is atypical and very rare for a patient to be asymptomatic late in pregnancy and for the pregnancy to result in a live birth with no evidence of intrauterine growth restriction despite the unfavourable implantation site. This late term asymptomatic presentation despite routine antenatal care demonstrates a diagnostic challenge. Read More

Introduction: Post-term pregnancies are associated with greater risks for mother and child. Accurate determination of gestational age is necessary for safe care. Female fetuses have been shown to be smaller than males at the time of second-trimester ultrasound (US) examination, leading to underestimation of their age and, potentially, greater impacts of perinatal complications in post-term girls than in post-term boys.

Respiratory distress is a common symptom in the newborn. Surfactant deficiency in the preterm infant and meconium aspiration and transient tachypnea in the term newborn are among the most common causes of respiratory distress, but primary airway abnormalities can also present with respiratory distress in the newborn. Delay in diagnosis of airway abnormality can be life threatening. Read More

Respiratory disorders are the most frequent cause of admission to the special care nursery both in term and preterm infants. Pediatricians and primary care providers may encounter newborn infants with respiratory distress in their office, emergency room, delivery room, or during physical assessment in the newborn nursery. The authors have proposed a practical approach to diagnose and manage such infants with suggestions for consulting a neonatologist at a regional center. Read More
