Abstract:
Objective:To explore the prognostic indicators and influencing factors of neonatal asphyxia in Tibet.Methods:From March 2019 to March 2020, the clinical data of 126 asphyxiated newborns admitted to the neonatology department of Lhasa People's Hospital were retrospectively studied. According to the prognosis, they were divided into good prognosis group and poor prognosis group, and the clinical characteristics of the two groups were compared. The predictive value of Apgar score after birth, arterial blood gas analysis within 6 hours [pH, alkali residue (BE)] and their combined detection on the prognosis of asphyxiated newborns was analyzed. Logistic regression analysis was used to analyze the related factors affecting the prognosis of asphyxiated newborns.Results:31 cases (24.6%) in the poor prognosis group and 95 cases (75.4%) in the good prognosis group. The Apgar score at 1, 5 and 10 minutes after birth and pH and BE within 6 hours in the poor prognosis group were significantly lower than those in the good prognosis group (all P<0.05). The incidence of meconium stained amniotic fluid, fetal intrauterine distress, brain damage, lung damage, myocardial damage, kidney damage, abnormal coagulation function and multiple organ damage after asphyxia in the good prognosis group were significantly higher than those in the good prognosis group (all P<0.05). The Apgar score at the 1, 5 and 10 minutes after birth combined with arterial blood gas analysis (pH and BE) within 6 hours after birth had high predictive value for the prognosis of asphyxiated newborns, with the area under receiver operating characteristic (ROC) curve of 0.79, sensitivity of 68.4% and specificity of 90.3%. Multivariate regression analysis showed that meconium stained amniotic fluid ( OR=4.501, 95% CI: 1.262-16.056), lung damage ( OR=5.004, 95% CI: 1.007-24.866) and brain damage ( OR=10.786, 95% CI: 2.726-42.673) were independent risk factors affecting the prognosis of neonatal asphyxia ( P<0.05). Conclusions:In Tibet, there are many factors affecting the poor prognosis of neonatal asphyxia. High attention and intervention should be given to mothers in perinatal period and asphyxiated newborns in order to reduce the incidence of poor prognosis of neonatal asphyxia.
