Auxiliary effect and pain care of nano-silver-based temperature-sensitive gel on obstetric delivery

Abstract

To improve the safety of mothers and make delivery less painful we explored the auxiliary effect of the nano-silver-based temperature-sensitive gel in the vaginal delivery of primipara to reduce the pain during delivery. 120 primipara with full-term vaginal delivery were randomly divided into a conventional midwifery control group (group A), a birth canal protection group with traditional way (group B), and a nano-silver-based temperature-sensitive gel midwifery experimental group (group C). Labor time, the uterine bleeding volume at 2 hours postpartum, and the pain care of delivery were observed for each group. Postpartum follow-ups were performed on the maternal and fetus, to record the maternal soft birth canal injury, pelvic floor function recovery, adverse reactions, and Apgar score of the newborn. Compared with group A and group B, labor time (P < 0.05), uterine bleeding (P < 0.05), and the visual analog scale significantly decreased in group C (P < 0.05). Group C showed increased efficacy of pain care (P < 0.05). The incidence of cervical laceration, hematoma, and lateral episiotomy significantly decreased in the treatment group (P < 0.05). When lateral episiotomies did occur in group C the incidence of cervical laceration (0%) was significantly lower than that in group A (8.53%) and group B (4.26%) (P < 0.05). The Apgar score of newborns in group C significantly increased at 1 and 5 minutes after birth (P < 0.05) and maternal pelvic floor function score was significantly higher at 42 days postpartum (P < 0.05). Thus, the nano-silver-based temperature-sensitive gel has benefits for maternal and fetal health, as well as, pain management in obstetric delivery. These results support the wide used of nano-silver-based temperature-sensitive gel for vaginal delivery midwifery.
