Analysis Of The Influencing Factors Of Interpartum Fever Related To Epidural Labor Analgesia

Objective: To compare the related influencing factors that the febrile and non-febrile parturients who received epidural labor analgesia received during the delivery process or their own,and to explore whether the related factors can cause interpartum fever in the parturients with epidural labor pain,And explore whether the interpartum fever caused by labor analgesia may be related to infection.Methods: Parturients who underwent epidural analgesia during childbirth in the Obstetrics Department of Subei People’s Hospital from October 2019 to September 2020 were selected.After childbirth,the body temperature ≥37.5℃ was included in the fever group,and the parturients with body temperature<37.5℃ were included in the normal group.Record basic maternal information such as age;gestational age;BMI;primipara;premature rupture of membranes;gestational diabetes;high blood pressure during pregnancy;low amniotic fluid;anemia,etc.The time from premature rupture of the fetal membranes to the delivery of the fetus in the two groups was recorded;total labor;time of labor analgesia;artificial rupture of membranes;amniotic fluid pollution;use of oxytocin;number of vaginal examinations;whether balloon cervical ripening was performed.At the same time,the white blood cells,neutrophils and C-reactive protein indicators of the parturients were recorded before and after delivery.The data was statistically analyzed with SPSS 22.0 software.The count data of the influencing factors were represented by the composition ratio(%),and the χ2 test was performed.The measurement data was represented by the mean±standard deviation,and the t test was performed.Logistic regression analysis was performed on relevant influencing factors,and P<0.05 was statistically significant.Result:1.Univariate analysis of interpartum fever: A total of 647 cases of parturients were included in this study,including 114 cases of parturients in the fever group and 533 cases of parturients in the non-fever group.The age,gestational age,primipara,premature rupture of membranes,pregnancy There were no significant differences in diabetes,hypertension during pregnancy,oligohydramnios,artificial rupture of membranes,and anemia(P>0.05).The BMI of the two groups of mothers,whether a balloon was used to promote cervical ripening,blood loss,fetal weight,time from membrane rupture to fetal delivery,total labor,labor analgesic time,vaginal examinations,frequency of use of oxytocin,and amniotic fluid contamination The incidence rates were all different,and both were statistically significant(P<0.05).2.Multi-factor logistics regression analysis of interpartum fever: The results of the logistic regression analysis show that the BMI value,amniotic fluid pollution,the time from rupture of the membrane to the delivery of the fetus,the number of vaginal examinations,the time of labor analgesia and the total labor are all epidural delivery towns.The risk factors of interpartum fever caused by pain(P<0.05).3.Comparison of inflammatory indexes between the fever group and the non-febrile group: the white blood cell count and neutrophil count of the two groups were compared before delivery,and the difference was not statistically significant(P>0.05).The white blood cell count and neutrophil count of the fever group receiving epidural labor analgesia were significantly higher than that of the normal group(P<0.05).In the comparison of the two groups of maternal C-reactive protein,the postpartum C-reactive protein of the fever group was significantly higher than that of the control group(P<0.05)Conclusion:1.In the process of receiving epidural analgesia for delivery,high BMI value,amniotic fluid contamination,long time from rupture of the membrane to delivery of the fetus,too many vaginal examinations,long delivery analgesia time,and long total labor,etc.The factors are high-risk factors that cause interpartum fever during the period of epidural analgesia.2.Regardless of whether the mother has a fever or not,the postpartum inflammatory index of the parturient is higher than that of the prepartum.The increase of inflammatory indexes may be related to fever,but interpartum fever caused by epidural labor analgesia is caused by a variety of factors,and non-infectious factors are also important factors that cause interpartum fever.
