Abstract:
Objective To explore the impact of peak and duration of intrapartum fever on umbilical arterial blood gas analysis.Methods From January 2022 to December 2024,a total of 82 full-term singleton pregnant women after vaginal delivery in Hangzhou Women's Hospital with a system fever ≥38.0℃ were included as fever group.164 pregnant women with a body temperature＜38.0℃ during the same period were included as control group in a 1∶2 ratio.The umbilical arterial blood gas analysis was performed in all of them.General data,situation during childbirth and umbilical arterial blood gas analysis were compared between fever group and control group.The fever group was further divided into 3 subgroups,including 52 cases in subgroup A with temperature 38.0℃ to＜38.5℃,21 cases in subgroup B with temperature from 38.5℃ to＜39.0℃,9 cases in subgroup C with temperature ≥39.0℃.General data,situation during childbirth and umbilical arterial blood gas analysis of 3 subgroups were compared.Results There were no statistical significance in general data and situation during childbirth between fever group and control group(P＞0.05).Compared with control group,lower pH and base excess levels in umbilical artery blood as well as higher lactate levels in fever group with statistically significant differences(P＜0.05).There were no statistical significance in general data and situation during childbirth among subgroups(P＞0.05).pH,base excess and lactate levels in umbilical artery blood had no statistically significant differences among subgroups(P＞0.05).Logistic regression analysis showed that the fever duration was associated with umbilical artery acidosis(P=0.048,OR=1.005,95％CI:1.000-1.009).Conclusion Intrapartum fever leads to a decrease in pH and base excess in umbilical artery blood,as well as an increase in lactate levels.The peak of intrapartum fever leads no statistically significant differences in umbilical arterial blood gas analysis.For women with fever ≥38.0℃,controlling fever time may be helpful to reduce the incidence of acidosis and neonatal morbidity.
