    Abstract
  •   Objective  To investigate and analyse the situation of episiotomy in vaginal delivery to provide intervention direction for improving the quality of midwifery and reducing the rate of episiotomy.  Methods  The convenience sampling method was used to conduct a cross-sectional survey of vaginal delivery patients in the Gaoxin Branch of the First Affiliated Hospital of Anhui Medical University from January 1 to December 31, 2019, including their age, times of delivery, course of delivery, gestational weeks, pregnancy complications or/and complications, perineum incision and its indications. The perineum incision rate and its influencing factors were statistically analyzed.  Results  A total of 1 992 cases of vaginal delivery were included, of which 700 cases underwent episiotomy. The annual average rate of episiotomy was 35.14%. The top three indications for perineotomy were poor perineal condition (356 cases, 50.86%), abnormal foetal heart rate (190 cases, 27.14%) and amniotic fluid Ⅲ degree contamination (75 cases, 10.71%). Univariate analysis showed that age (Z=4.586, P < 0.001), education level(Z=2.414, P=0.016) of pregnant women, working years of midwives (Z=2.398, P=0.016), parity (Z=14.307, P < 0.001), the second stage of labour time (χ2=300.016, P < 0.001), gestational weeks (Z=3.104, P=0.002), with or without pregnancy complications or complications (χ2=60.435, P < 0.001) and scar uterus (χ2=6.591, P=0.010) were the influencing factors of episiotomy. Multivariate logistic regression analysis based on the results of univariate analysis showed that the age of pregnant women >35 years, midwife working experience >10 years, the second stage of labour time >120 minutes and scar uterus were independent risk factors of episiotomy (all P < 0.05).  Conclusion  At present, the rate of episiotomy remains high, and the training of midwives needs to be further strengthened. This work can be used to enhance the quality of midwifery, reduce the rate of episiotomy and improve the quality of postpartum life by improving the midwife ' s comprehensive assessment of perineal conditions, labour process and maternal and foetal conditions.
