Use of lung ultrasound in neonates during the COVID-19 pandemic.

Radiol Bras 2020 Nov-Dec;53(6):401-404

Instituto da Criança do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (ICr/HC-FMUSP), São Paulo, SP, Brazil.

In the current pandemic, caused by infection with severe acute respiratory syndrome coronavirus 2, ultrasound has played a fundamental role in patients who develop the resulting disease, designated coronavirus disease 2019 (COVID-19). In this study we present ultrasound images of the lungs of neonates with a suspected or confirmed diagnosis of COVID-19, distinguishing between the changes related to COVID-19 and those unrelated to the disease. Ultrasound examinations were performed by a pediatric sonographer. Read More

Recent Advances in Pathophysiology and Management of Transient Tachypnea of Newborn.

J Perinatol 2021 01 4;41(1):6-16. Epub 2020 Aug 4.

Department of Pediatrics, Case Western Reserve University, UH Rainbow Babies & Children's Hospital, Cleveland, OH, USA.

Transient tachypnea of newborn (TTN) results from failure of the newborn to effectively clear the fetal lung fluid soon after birth. TTN represents the most common etiology of respiratory distress in term gestation newborns and sometimes requires admission to the neonatal intensive care unit. TTN can lead to maternal-infant separation, the need for respiratory support, extended unnecessary exposure to antibiotics and prolonged hospital stays. Read More

Fetal Pulmonary Artery Acceleration/Ejection Ratio for Transient Tachypnea of the Newborn in Uncomplicated Term Small for Gestational Age Fetuses.

Eur J Obstet Gynecol Reprod Biol 2020 Apr 14;247:116-120. Epub 2020 Feb 14.

Department of Neonatology, Kayseri City Hospital, Kayseri, Turkey. Electronic address:

Objective: Transient tachypnea of the newborn (TTN) is the leading cause of neonatal morbidity in preterm deliveries and has been reported in term small-for-gestational-age (SGA) fetuses; therefore, determination of fetal lung maturity before delivery is extremely important. Our present study aimed to evaluate the ratio of fetal pulmonary artery acceleration time to ejection time (At/Et) in uncomplicated term SGA fetuses and whether this ratio changes with TTN.

Study Design: One hundred seventy-five pregnant women with uncomplicated pregnancies who delivered after 37 gestational weeks were included in this cross-sectional study. Read More

Thoracic ultrasound accuracy for the investigation of initial neonatal respiratory distress.

Arch Pediatr 2019 Nov 17;26(8):459-465. Epub 2019 Oct 17.

Service d'imagerie médicale, hôpital Nord, AP-HM, 13015 Marseille, France.

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.

The utility of routine echocardiography in newborn infants with a persistent oxygen requirement

Ir Med J 2018 05 10;111(5):755. Epub 2018 May 10.

Department of Neonatology, the Rotunda Hospital, Dublin, Ireland.

In the era of antenatal screening for congenital heart disease (CHD), infants presenting with an undiagnosed significant CHD are rare. However, term infants admitted with an initial diagnosis of TTN and a prolonged oxygen requirement often undergo an echocardiogram. We aimed to assess whether this practice yields any additional cases of undiagnosed CHD. 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

Department of Radiology, Arkansas Children׳s Hospital, University of Arkansas for Medical Sciences, Little Rock, AR.

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

Pediatr Clin North Am 2015 Apr;62(2):453-69

LSU Health, 1501 Kings Highway, Shreveport, LA 71130, USA.

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
