Influence of different intervention methods on the second stage of labor of primipara / 中国实用护理杂志

Objective To study the influence on primipara's second stage of labor with the methods of Changqiang-pressing and Vaginal-pressing. Methods 180 primipara in the second stage of labor were randomly divided into 3 groups of 60 each, in which Changqiang-pressing, Vaginal-pressing and general guidance (the control group) were used respectively. The duration of uterine contraction and second stage of labor, vaginal bleeding amount in 2 hours after delivery, mode of delivery, perineal injury and birth case would be evaluated. Results The results in both Changqiang-pressing group and Vaginal-pressing group were statistically significant when compared with the control group, but there was no significant difference between Changqiang-pressing group and Vaginal-pressing group. Conclusions Using Changqiang-pressing and Vaginal-pressing can promote the progress of the second stage of labor for primipara, reduce the rate of cesarean section and neonatal asphyxia, and improve the quality of obstetric department.

Application effect of massaging Changqiang acupuncture point during the second labor course / 中国实用护理杂志

Objective To investigate the effect of massaging Changqiang acupuncture point during the second labor course of primiparas. Methods 124 primiparas were randomized into the observation group(63 cases)and the control group (61 cases). In the observation group, after entering the second stage of labor, Changqiang point was massaged upwards by using index finger and middle finger, and at the same time primiparas were guided to hold breath to coordinate with uterine contraction to make effort to the anus point which was massaged. While the control group were directed with routine way of correctly using abdominal pressure during process of uterine contraction in the second stage of labor. Results The lasting time of uterine contraction was significantly longer in the observation group than in the control group, the time of second stage of labor was shorter, and the amount of postpartum hemorrhage in the observation group was less than those in the control group. Conclusions Application of massaging Changqiang acupuncture point could prolonge the time of uterine contraction, advance the progress of second stage of labor, and decreased the amount of postpartum hemorrhage.
