Physiologic reduced oxygen protocol decreases the incidence of threshold retinopathy of prematurity (original) (raw)

Transactions of the American Ophthalmological Society

To report the incidence of threshold retinopathy of prematurity (ROP) in very low birth weight premature infants from three neonatal intensive care units (NICUs) before and after implementation of a physiologic reduced oxygen protocol (PROP). PROSPECTIVE, OBSERVATIONAL STUDY OF DATA FROM THREE NICUS: Cedars-Sinai Medical Center (CSMC), Los Angeles; Good Samaritan Hospital (GSH), Los Angeles; and National University Hospital (NUH), Singapore. PROP was implemented to keep oxygen saturation values by pulse oximeter (SpO2) between 83% and 93% (as described in Pediatrics 2003;111:339-345). The incidence of threshold ROP in the year before and the year after implementation of PROP was compared. Data from the transition year were not included in the analysis. THE INCIDENCE OF THRESHOLD ROP DECREASED IN EACH CENTER: CSMC, 3.3% to 0.0% (3/92 to 0/88); GSH, 14.8% to 4.9% (8/54 to 2/41); and NUH, 6.7% to 0.0% (3/45 to 0/30). Overall, the incidence of threshold ROP decreased from 7.3% to 1.3%. ...
