Effect of auricular magnetic bead pressing on maternal body temperature, inflammatory response and placental pathological results in labor analgesia

Abstract

To observe the effects of auricular magnetic bead pressing on maternal body temperature, inflammatory response and placental pathological results in epidural labor analgesia. 180 parturient who volunteered for labor analgesia were randomly divided into epidural group (n=90, epidural labor analgesia) and auricular pressing group (n=90, epidural labor analgesia combined auricular pressing). The tympanic temperature before labor analgesia (T1), 2 h (T2), 4 h (T3) and 4 h after labor analgesia (T4) were recorded. The total duration of labor, duration of labor analgesia, PCEA compression times, labor analgesia dose, cesarean section rate was counted, and the changes in serum IL-6 level and placental pathologyresults of the two groups were analyzed. There was no significant difference in age, BMI, gestational age, duration of labor, duration of analgesia and rate of cesarean section between groups(P>0.05). Times of PCEA compressions and labor analgesic dose in auricular group were lower than that in epidural group (P<0.05). There was no difference in tympanic temperature between two groups at T1 (P>0.05), and the tympanic temperature at T3 and T4 was higher than that at T1 (P<0.05). The tympanic temperature in T3 and T4, and incidence of intrapartum fever in the auricular group was lower than that in the epidural group (P<0.05).There was no difference in the prenatal serum IL-6 level between groups (P>0.05), and the postpartum serum IL-6 level was higher than that before labor in either group (P<0.05).The postpartum serum IL-6 level and the incidence of HCA in the auricular point group were lower than those in epidural group (P<0.05). Magnetic beads auricular pressing therapy has advantages in reducing intrapartum fever by modulating maternal inflammation and reducing the dosage of local anesthetics effectively during epidural labor analgesia.
