Comparison with other studies
A lot of research has varified the diagnostic value of LUS on neonatal
lung diseases2, 28, 33-34. The difference between
theirs and ours is we focused on predictive value. As we found these
abnormal LUS sign at early stage right after birth do not have
significant specificity for certain diseases, we only use LUS to predict
respiratory need that concerns all kinds of severe lung diseases.
Recently, some study also paied attention to predictive value of LUS in
neonatology14-16, 35. They evaluated mostly predictive
value of PS need in preterm infants whereas we study need of all kinds
of respiratory support, including CPAP and MV that closely relate to
severe lung disease. So we believe our study is a good complement to
current studies and very useful since it can provide evidence to offer
early interventions to those high risk infants.
