transient tachypnea of the newborn

(redirected from Transient tachypnoea of newborn)

tachypnea

 [tak″ip-ne´ah]
very rapid respirations, seen especially in high fever when the body attempts to rid itself of excess heat. The rate of respiration increases at a ratio of about eight breaths per minute for every degree Celsius above normal. Other causes include pneumonia, compensatory respiratory alkalosis as the body tries to “blow off” excess carbon dioxide, respiratory insufficiency, lesions in the respiratory control center of the brain, and salicylate poisoning. See also hyperpnea and hyperventilation.
transient tachypnea of the newborn a self-limited elevation of the respiratory rate in newborns due to delayed clearing of fetal lung water.

transient tachypnea of the newborn

a syndrome of generally mild tachypnea in otherwise healthy newborns, lasting usually only about 3 days.

(TTN) (tran'sē-ĕnt tă-kip'nē-ă nū'bōrn)
Respiratory distress presenting in the first few hours of life, generally resolving in 12-24 hours.

transient tachypnea of the newborn

Abbreviation: TTN
A self-limited condition often affecting newborns who have experienced intrauterine hypoxia resulting from aspiration of amniotic fluid, delayed clearance of fetal lung fluid, or both. Signs of respiratory distress commonly appear within 6 hr after birth, improve within 24 to 48 hr, and resolve within 72 hours of birth, without respiratory assistance.

Respiratory distress being a symptom complex represents a heterogeneous group of illness with varying incidence, aetiology, clinical causes and outcome.8 A wide variety of pathologic lesions may be responsible for respiratory disturbances, including pneumonia (22.5%), hyaline membrane disease (HMD), respiratory distress syndrome (RDS) (20.8%), meconium aspiration syndrome (MAS) (16.7%), sepsis (12.5%), transient tachypnoea of newborn (TTN) (11.7%), birth asphyxia (BA) (7.5%), congenital heart disease (CHD) (4.3%) and others.9 While knowing the frequency of various aetiologies, investigations can be minimised by investigating first the most common cause of respiratory distress in our local settings, and hospital policies can be made according to most common aetiologies and their outcomes.
Dutta et al [7] and Kumar et al [8] in their study had a highest incidence of transient tachypnoea of newborn. Mathur et al [9] had pneumonia as the majority of cases.
Total 13 neonates admitted in NICU; 8 (16%) from nuchal cord group (4 neonates for perinatal asphyxia, 2 neonates for transient tachypnoea of newborn and 2 neonates for low birth weight), and 5(10%) from non-nuchal cord group (3 neonates for perinatal asphyxia, 1 neonate for transient tachypnoea of newborn and 1 neonate for VSD).
