Why the study?

Does an initially prolonged right ventricular systolic time interval predict the development of severe transient tachypnea in term neonates?

Population

42 term neonates with transient tachypnea (TTN)

Comparison

Right ventricular systolic time interval ratio >… vs Right ventricular systolic time interval ratio ≤…

Design

Cohort

Key result

An initially prolonged right ventricular systolic time interval (ratio > 0.50) strongly predicted the development of severe transient tachypnea in term neonates (RR 17.5, p<0.001).

Overview

May warrant early echocardiography for risk stratification in transient tachypnea; leaves open whether RVSTI-guided care improves outcomes.

Study Design

Type

Cohort (n=42)

Structured PICO

Does an initially prolonged right ventricular systolic time interval predict the development of severe transient tachypnea in term neonates?

P
Population
42 term neonates with transient tachypnea evaluated with echocardiography before the age of 4 hours.
E
Exposure
Right ventricular systolic time interval (RVSTI) ratio > 0.50 measured by echocardiography before the age of 4 hours
C
Comparator
Right ventricular systolic time interval (RVSTI) ratio ≤ 0.50
O
Outcome
Development of severe transient tachypnea (TTN)hard clinical

Main Result

Relative Risk: 17.5

p-value: p=<0.001

Initial measurement of right ventricular systolic time intervals by echocardiography before 4 hours of age strongly predicts the development of severe transient tachypnea in term neonates.

Cite This Study

Kati Heinonen (1983) conducted a cohort in Transient tachypnea (TTN) (n=42). Right ventricular systolic time interval (RVSTI) ratio > 0.50 vs. RVSTI ratio ≤ 0.50 was evaluated on Development of severe TTN (RR 17.5, p=<0.001). An initially prolonged right ventricular systolic time interval (ratio > 0.50) strongly predicted the development of severe transient tachypnea in term neonates (RR 17.5, p<0.001).
