Despite the advances in neonatology since the 1960s which have led to a significant decrease in mortality from HMD, the prevalence of BPD has remained remarkably stable. Of course, with the newer 36wkBPD definition, the incidence has declined compared to the 80s when the 28dyBPD definition was used routinely. However, the increased number of very small survivors means that the total number of BPD cases has remained about the same or slightly increased. It would seem that BPD is one of the prices a very-low-birth-weight (VLBW) baby pays for his increased survival.
Most people also acknowledge that the severity of BPD has decreased during the surfactant era. It was not uncommon presurfactant for a baby with BPD to remain on the ventilator in high amounts of oxygen for months after birth. Nowadays that same baby is in phase 2 in nasal cannula O2.
