Background:
The most common reason of respiratory distress in the newborn is transient tachypnea of the newborn (TTN). There are some reports saying that TTN is associated with increased frequencies of wheezing attacks.
Objectives:
The aims of this study were to determine the risk factors associated with TTN and to determine the association between TTN and the development of wheezing syndromes in early life.
Materials And Methods:
In a historical cohort study, we recorded the characteristics of 70 infants born at the Shohadaye Kargar Hospital in Yazd between March 2005 and March 2009 and who were hospitalized because of TTN in the neonatal intensive-care unit. We called their parents at least four years after the infants were discharged from the hospital and asked about any wheezing attacks. Seventy other infants with no health problems during the newborn period were included in the study as the control group.
Results:
The rate of wheezing attacks in newborns with TTN was more than patients with no TTN diagnosis (P = 0.014). TTN was found to be an independent risk factor for later wheezing attacks (relative risk [RR] = 2.8).
Conclusions:
The most obvious finding of this study was that TTN was an independent risk factor for wheezing attacks. So long-term medical care is suggested for these patients who may be at risk, because TTN may not be as transient as has been previously thought.

Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by...

A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
