Clinical Analyses Of High-risk Factors Of Retinopathy Of Prematurity

Objective: The incidence of the survey preterm children retinopathy （ROP）, andanalysis of related risk factors, clinical and better pre-occurrence of ROP, reduce theblindness rate to provide a reference. Methods: March2010to2011in December, wasborn in Xinjiang Medical University First Affiliated Hospital of obstetric Checkneonatology gestational age＜34weeks or birth weight＜2000g preterm children272cases, four weeks after birth, corrected gestational age32weeks, fundus examination,according to the ROP International Diagnostic staging, stage at diagnosis, analysis of therelationship of ROP and a variety of factors. Results: In the screening of272cases ofpreterm children, of ROP26patients, the incidence rate of9.5%. Phase I of the disease19cases, II lesions, four cases of stage Ⅲ lesions in two cases, IV lesions,2patientsrequired laser treatment, one cases of blindness. By gestational age, birth weight, oxygen,blood transfusions, apnea, infection, respiratory distress syndrome, mechanicalventilation, gender （male/female）, mode of delivery （cesarean section/naturaldelivery）, premature rupture of membranes, multiple pregnancy risk factors such assingle-factor analysis showed that gestational age, birth weight, oxygen, bloodtransfusion, smoking distress syndrome, mechanical ventilation with ROP association （P＜0.05）. Logistic regression equation to analyze the results also show that the abovefactors are the risk factors of ROP. Conclusion: Higher hospital in preterm infants theincidence of ROP, this study showed that gestational age, birth weight, time of oxygen,mechanical ventilation, respiratory distress syndrome, transfusion risk factors for theoccurrence of ROP. And the hospital32to33⁺⁶ weeks premature children and childrenwith mechanical ventilation, oxygen concentration＞60%occurred for ROP risk group.
