Transitory Tachypnea of the Newborn

Tachypnea Transient Newborn


Presentation

  • Peripheral air trapping is present, leading to increased lung volume and scattered atelectasis. Small bilateral pleural effusions may be present. Air leak is rare. The chest x-ray returns to normal in 48-72 hours.[virtualpediatrichospital.org]
  • Infants present in respiratory distress, classically with grunting and nasal flaring, within the first six hours of life. There can be mild cyanosis.[radiopaedia.org]
  • OBJECTIVES: To prospectively compare outcomes of infants presented with classic TTN who were treated with or denied from intravenous antibiotics. METHODS: A prospective cohort study was conducted on all infants admitted with classic TTN.[content.iospress.com]
  • […] last authored: July 2010, Amanda Li last reviewed: Introduction Transient Tachypnea of the Newborn (TTN) describes signs of mild respiratory distress presenting in the first few hours of life.[sharinginhealth.ca]
  • CLINICAL PRESENTATION They have signs of respiratory distress such as tachypnea (respiratory rate 60 breaths/min(, nasal flaring, grunting, and intercostal, subcostal, and/or suprasternal retractions.[slideshare.net]
Pulmonary Disorder
  • Our multi-disciplinary team of pediatric pulmonologists, pulmonary nurse specialists, physical therapists and social workers diagnose and provide care to children with numerous pulmonary disorders.[childrenshospital.org]
Barrel Chest
  • In addition, the infant may demonstrate a barrel chest and coarse breath sounds. Within 24 to 48 hours, the clinical manifestations of respiratory distress usually disappear.[thoracickey.com]

Workup

Right Pleural Effusion
  • Case Images Diagnosis Transient tachypnea of the newborn Findings CR – Cardiomegaly, vascular congestion and small right pleural effusion. Followup radiograph the following day is normal.[advancedradteaching.com]
Decreased Lung Compliance
  • As this condition worsens, the infant develops pulmonary capillary congestion, interstitial edema, decreased lung compliance, decreased tidal volume, and increased dead space.[thoracickey.com]

Treatment

  • Clinical treatment with antibotics was also similar between the groups (treatment 73%, control 40%, P 0.29). Figure 2 Mean (s.d.) of maximum respiratory rate during study observation period.[nature.com]
  • Conventional treatment involves supplemental oxygen, withholding enteral feeds and administration of intravenous fluids and antibiotics. Rarely, infants require CPAP and mechanical ventilation.[eurekaselect.com]
  • What complications might you expect from the disease or treatment of the disease? Since the disease is often self-limited and benign, no treatment is recommended.[clinicaladvisor.com]
  • Treatments Treatments Specific treatment for transient tachypnea of the newborn will be determined by your baby's physician based on: Your baby's gestational age, overall health, and medical history Extent of the condition Your baby's tolerance for specific[childrensnational.org]

Prognosis

  • Hence lactate,LDH and Cys-C can be used for early diagnosis of TTN and early treatment with better prognosis.[omicsonline.org]
  • In the literature, TTN has been reported to have an excellent prognosis, although it can occasionally cause complications in the acute period [ 4 ].[agialpress.com]

  • Mortality/Morbidity Transient tachypnea of the newborn is generally a self-resolving disorder with excellent prognosis. It frequently resolves over a 24-hour to 72-hour period.[emedicine.medscape.com]
  • The prognosis for transient tachypnea of the newborn is generally excellent, with full recovery expected in three-quarters of affected infants by 48 hours of life.[clinicaladvisor.com]

Etiology

  • Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology.[icd10coded.com]
  • The most common etiology of neonatal respiratory distress is transient tachypnea of the newborn ; this is triggered by excessive lung fluid, and symptoms usually...[acronymattic.com]
  • Etiology/Pathophysiology: Retention or delay in clearing fetal lung liquid. Prior to birth the fetal lungs and airways are filled with fluid formed from an ultrafiltrate of plasma.[virtualpediatrichospital.org]
  • The major pathologic or structural changes associated with TTN are as follows: Etiology and Epidemiology TTN affects 1% to 2% of all newborns. Classically, TNN is most often seen in full-term infants.[thoracickey.com]
  • Ongoing controversies regarding etiology, diagnosis, treatment First, there is ongoing debate about the high rate of cesarean sections, both primary and repeat, which have undoubtedly increased the incidence of TTN.[clinicaladvisor.com]

Pathophysiology

  • This review focuses on TTN, with emphasis on fetal lung fluid mechanics and possible mechanisms of fetal lung fluid resorption as well as its pathophysiology, clinical and diagnostic features, and management.[pedsinreview.aappublications.org]
