ObjectiveTo investigate the related factors of the retina1 hemorrhage in newborns. Methods9558 newborns included in this observation between March of 2012 and July of 2013 in our hospital. The fundus was examined by the fully-integrated wide-field digital imaging system RetCamⅢat 0-4 days after born. According to the literature, retinal hemorrhage was classified into degreeⅠ, ⅡandⅢ. The condition for baby and the mother during pregnancy were correlatively analyzed. The other factors were analyzed including twins, premature delivery, big baby, mode of delivery, fetal birth, forceps delivery, suction delivery, asphyxia, jaundice, ABO hemolytic, cranial hematoma, intracranial hemorrhage, maternal age, first-time mom, the maternal previous mode of production, emergency delivery, the first stage of labor prolonged, the second stage of labor prolonged, the third stage of labor prolonged, pregnancy-induced hypertension, gestational diabetes, oxytocin, prenatal body mass index (BMI). Multivariate logistic regression analysis was used. ResultsIn 9558 cases of newborns, retinal hemorrhages were found in 2753 infants (28.8%), including 1137 degreeⅠ(41.3%), 895 degreeⅡ(32.5%) and 721 degreeⅢ(26.2%). Multivariate logistic regression analysis showed that the mode of delivery, asphyxia, jaundice, advanced maternal age, maternal previous birth, prenatal BMI is a risk factor for neonatal values retinal hemorrhage (r=0.146, 5.841, 1.847, 0.071, 0.246, 0.965;P < 0.05). The degree of fundus hemorrhage was not related to birth weight and BMI (P > 0.05). ConclusionsThe neonatal retinal hemorrhage rate was 28.8%. Mode of delivery, asphyxia, neonatal jaundice, maternal age, the previous mode of delivery of mothers with more than one previous birth, prenatal BMI values may be risk factors lead to retinal hemorrhage.
High-flow nasal cannula (HFNC) oxygen therapy, which is important in noninvasive respiratory support, is increasingly being used in critically ill neonates with respiratory failure because it is comfortable, easy to set up, and has a low incidence of nasal trauma. The advantages, indications, and risks of HFNC have been the focus of research in recent years, resulting in the development of the application. Based on current evidence, we developed guidelines for HFNC in neonates using the grading of recommendations assessment, development and evaluation (GRADE). The guideline was formulated after extensive consultations with neonatologists, respiratory therapists, nurse specialists, and evidence-based medicine experts. We have proposed 24 recommendations for 9 key questions. This guideline aims to be a source of evidence and references of HFNC oxygen therapy in clinical practice, and so that more neonates and their families will benefit from HFNC.
