It is important to follow your child’s treatment plan and get regular care. Introduction: Respiratory distress is the most common cause of NICU admissions in newborns. Benetti E, Fanaroff A, Anadkat JS, Oyelese Y, Without surfactant, there is higher pulmonary surface tension, atelectasis, and ventilation/perfusion mismatch resulting in hypoxia, hypercapnia, and acidosis. The Effects of Maternal Preeclampsia on the Development of Pulmonary and Vascular Dysfunction in Infants. Culin A, CHRISTIAN L. HERMANSEN, MD, MBA, and ANAND MAHAJAN, MD, Lancaster General Hospital, Lancaster, Pennsylvania. On examination, a loud second heart sound and systolic murmur may be heard. Mirzaei F, The newborn weighed 4 lb, 2 oz and had Apgar scores of 5 and 5. Corsello G. Pediatrics. The effects of inhaled albuterol in transient tachypnea of the newborn. Use of leukocyte counts in evaluation of early-onset neonatal sepsis. One-fourth of cases are critical, necessitating surgery in the first year, and one-fourth of those newborns do not survive the first year.52 Newborns with cyanotic heart disease present with intense cyanosis that is disproportionate to respiratory distress. The U.S. Department of Health and Human Services recommends screening newborns for critical congenital heart defects using pulse oximetry before hospital discharge, but at least 24 hours after birth. Chest radiography (Figure 337) shows a diffuse ground-glass appearance with air bronchograms and hypoexpansion, and blood gas measurements show hypoxemia and acidosis. Chest radiography showed increased pulmonary vascularity. BMJ. Massaro A, Respiratory distress of the term newborn infant. The newborn may also have lethargy, poor feeding, hypothermia, and hypoglycemia. Carlo WA; Di Renzo GC, http://ispub.com/IJPN/11/2/5613. Mimouni FB, Rennie JM, Newborns should be screened for critical congenital heart defects via pulse oximetry after 24 hours but before hospital discharge. Auckland District Health Board. RDS is more common in white males and newborns born to mothers with diabetes mellitus.35,36, RDS symptoms (i.e., tachypnea, grunting, retractions, and cyanosis) occur immediately after birth. Hermansen CL, Pediatrics. Himayun M, Cesarean delivery without labor bypasses this process and is therefore a risk factor for TTN.25 Surfactant deficiency may play a role in TTN. Blood cultures, serial complete blood counts, and C-reactive protein measurement are useful for the evaluation of sepsis. Birnkrant DJ, Late-preterm birth: does the changing obstetric paradigm alter the epidemiology of respiratory complications? 2012;7(6):1–11. Early surfactant administration with brief ventilation vs. selective surfactant and continued mechanical ventilation for preterm infants with or at risk for respiratory distress syndrome. 26. American College of Obstetricians and Gynecologists; Society for Maternal-Fetal Medicine. Ohlsson A, Taha S, Chest radiograph of an infant with transient tachypnea of the newborn. Differential Diagnosis of Respiratory Distress in the Newborn. Approximately 10% of neonates require respiratory support immediately after delivery due to transitional problems or respiratory disorders, and up to 1% of neonates are in need of resuscitation. Asenjo M. Imaging in transient tachypnea of the newborn. He or she might not be able to get enough oxygen to support the body's organs. Treatment before … The most common causes of respiratory distress in newborns are transient tachypnea of the newborn (TTN), respiratory distress syndrome (RDS), meconium aspiration syndrome, pneumonia, sepsis, pneumothorax, and delayed transition. A chest radiograph consistent with mild respiratory distress syndrome or transient tachypnoea of the newborn. 13. Role of C-reactive protein in early onset neonatal sepsis. 2005;147(4):486–492. Respiratory distress is a leading cause of death in newborns, particularly premature infants. 27. Serra G, 2008;36(3):191–196. Furosemide for transient tachypnoea of the newborn. To participate in this study, your newborn must have been born prematurely between 24 and 36 weeks’ gestation and not have any congenital heart or lung defects. 46. Surfactant is usually given through a breathing tube. 2008;121(6):1301]. Changes in phospholipid composition of tracheal aspirates from newborns with hyaline membrane disease or transient tachypnoea. Physical examination revealed a pulse of 152 beats per minute and respiratory rate of 82 respirations per minute with wet sounding breaths. They may present with grunting, retractions, nasal flaring, and cyanosis. Weiner J. Crit Care Nurs Clin North Am. Wong C, Respiratory distress syndrome is a lung disorder in premature newborns in which the air sacs in their lungs do not remain open because a substance that coats the air sacs called surfactant is missing or insufficient. Bhandari A, Women with inadequate prenatal care may deliver babies with lower birth weights and increased risk of admission to the neonatal intensive care unit.5 Antenatal corticosteroid use in threatened preterm deliveries from 24 to 34 weeks' gestation significantly reduces the incidence and severity of respiratory distress.6 Because cesarean delivery is a risk factor for respiratory distress, especially in premature infants, reducing these surgeries when possible could reduce the incidence of the condition.7. Certain factors may increase the risk that your newborn will have RDS.

Baldisserotto M, Bateman BT, Johansen H, MAS is more common in term and post-term newborns. Wiswell TE, 2011;159(5):750–754. Kim KS. See the CME Quiz Questions. Lorah KN. Furosemide (Lasix) may cause weight loss and hyponatremia, and it is contraindicated despite the excess pulmonary fluid present in newborns with TTN.31 Fluid restriction in TTN is beneficial, reducing the duration of respiratory support and hospital-related costs.32 Inhaled albuterol reduces tachypnea duration and the need for oxygen therapy, although standardized guidelines are still needed.33 Antibiotics are not indicated in TTN.34 Antenatal corticosteroids given 48 hours before elective cesarean delivery at 37 to 39 weeks' gestation reduce TTN incidence, although it is unclear whether delaying cesarean delivery until 39 weeks' gestation is preferable.6, Newborns born before 34 weeks' gestation may have respiratory distress secondary to surfactant deficiency and lung immaturity. Copyright © 2015 by the American Academy of Family Physicians. This study is located in Chicago, Illinois. Bronchopulmonary dysplasia: an update. Neonatal RDS occurs in infants whose lungs have not yet fully developed. Surfactant coats the insides of the air sacs, or alveoli, in the lungs. Receive automatic alerts about NHLBI related news and highlights from across the Institute. Saarela T, Serial complete blood counts, C-reactive protein measurements, and blood cultures help with diagnosis and treatment. It can cause babies to need extra oxygen and help breathing. 44. Rare causes include choanal atresia; diaphragmatic hernia; tracheoesophageal fistula; congenital heart disease; and neurologic, metabolic, and hematologic disorders.
