Objective: To quantitatively evaluate the clinical effects of Doula labor analgesia meter on the vaginal delivery. Methods: A total of 2 313 cases of full-term pregnancy vaginal trial delivery maternal were selected in our hospital from October 2014 to July 2015. According to the mode of delivery, patients are divided into control group (n=1 252), observation group A (n=705) and observation group B (n=356). The control group were given conventional vaginal delivery method, observation group A were given epidural analgesia labor measures, and the observation group B were given T-4A-type doula labor analgesia meter. The maternal mode of delivery, duration of labor, delivery and the degree of pain and birth outcomes for mother and child in these groups were observed successively. Results: The labor pain level of observation group A and observation group B were better than control group, with statistical significance (P<0.05), but there was no significant difference between the two groups (P>0.05). The maternal labor time, the rate of vaginal delivery, postpartum hemorrhage 2 h status in observation group B were significantly better than those in the control group and observation group A, with statistical significance (P<0.05). Conclusion: The implementation of doula labor analgesia meter can significantly shorten the maternal labor time, relieve pain and improve productivity in the probability of vaginal delivery, maternal and neonatal safety of birth also has an active security role.
