Objective:To explore the effect of the labor abdominal pressure training device on the second stage of labor and the outcome of labor in primiparas undergoing epidural analgesia.Methods:The healthy primiparas who had patient controlled epidural analgesia were randomly divided into the observation group (126 cases) and the control group (122 cases). The control group used conventional oral instruction to force after entering the second stage of labor. The women in the observation group used the labor abdominal pressure training device to guide the force. The time required to learn to exert force, the second stage of labor and the outcome of labor were observed.Results:The parturient women learned the correct time to exert force, the time of the second stage of labor, the self-efficacy score of the second stage of labor, and the post-natal fatigue score were (13.56 ± 5.32) min, (76.32 ± 10.58) min, (121.38 ± 17.52)points, (8.56 ± 0.72) points in the observation group, and (25.47 ± 7.65) min, (105.21 ± 18.41) min, (101.42 ± 14.32) points, (13.31 ± 0.46) points in the control group, the differences between the two groups were statistically significant ( t values were -10.326-11.002, all P<0.05). The maternal spontaneous delivery rate, fetal assisted delivery rate, forceps assisted delivery rate, perineal lateral cut rate, perineal median cut rate, perineal tear>Ⅰ°rate were 94.44% (119/126), 4.76% (6/126), 0.79% (1/126), 9.52% (12/126), 11.11% (14/126), 6.35% (8/126) in the observation group, and 85.25% (104/122), 12.30% (15/122), 2.46% (3/122), 29.51% (36/122), 4.10% (5/122), 9.84% (12/122) in the control group,the differences between the two groups were statistically significant ( χ2 values were 4.582-9.437, P<0.05 or 0.01). Conclusions:The use of an abdominal pressure training device for labor in patient controlled epidural analgesia for pregnant women can shorten the second stage of labor and study the time of exertion, improve the self-efficacy of the second stage of labor, reduce the degree of perineal injury and fatigue, reduce the vaginal birth rate, and help protect Mother and child are safe.

Objective To study the treatment of neonate-infants after open-heart surgery during perioperafive period.Methods The clinical data of 1619 neonate-infants during perioperative period were analyzed.Results 68 cases died,mortality 4.2%.Postoperative complication 190 cases(11.7%).Conclusion The management of components and quantities of the infusion,admistration of cardiovascular drugs,the management of respiratory tracts and the protection of heart function,ale main points of perioperafive therapy of neonate-infants after open-heart surgery.

Objective To analyze the clinical effect of a bifurcated ball frame designed for undergraduate research to assist hand-knee position,avoid physical exertion and increase comfort.Methods Randomized controlled trials consisted of 260 occipital (posterior) primiparous women born during labor,and were randomly divided into the observation group and the control group with 130 cases each.The observing group's mothers were on the yoga ball on the device.The angle and height of the frame and the ball plate were adjusted according to the maternal body type,so that the yoga ball at the chest and the cross could effectively support the maternal weight loss knee burden,and both sides of the small abdominal yoga ball could be effectively posted.After the adjustment was completed,the maternal relaxes and gently shakes the body in one direction so that the small yoga ball on the ventral side forms a continuous soothing push.The control group leaned forward on both knees (with protective gear) and supported themselves with both hands or both fists,swaying the pelvis or crawling forward.Comparing the two groups of vaginal delivery rate,maternal postural maintenance time,maternal dehvery experience,and effective correction rate of occipital position.Results The time of postoperative maintenance in the observation group was (49.51 ±10.62) minutes,and that of the control group was (18.31 ± 9.72) minutes.The difference between the two groups was statistically significant (t=6.69,P ＜0.05).The effective correction of abnormal fetal position rate,spontaneous delivery rate and comfort rate were 82.30％ (107/130),77.69％ (101/130),and 99.23％ (129/130),respectively in the observation group,and 27.69％ (36/130),33.85％ (44/130),3.84％ (5/130),respectively in the control group,the differences between the two groups were statistically significant (x2 =4.06,4.15,5.61,all P ＜0.05).Conclusions The undergraduate design of this sort of ball delivery group has a significant effect on the extraversion of the assisted position to the fetal position.
