Abstract:AIM: To analyze the incidence and oxygen related factors of retinopathy of prematurity(ROP)in Suzhou.
METHODS: In 234 cases of premature infants born from May 2011 to May 2012 in Suzhou and its surrounding areas, with birth weight from 650g to 2 550g and birth week from 27+4 weeks to 36 weeks. They were divided into oxygen group and non-oxygen group. Chi-square test was used for statistical analysis.
RESULTS: Effects of oxygen inhalation had no significant difference on the incidence of ROP.
CONCLUSION: Test results indicate that after the control of oxygen concentration, the effects of oxygen inhalation has no significant difference on the incidence of ROP which is not a direct cause of ROP. Limited oxygen use can not prevent the occurrence of ROP.
