[Effects of the combined therapy of the auricular-point pressure at the free position and the unprotected perineal delivery technique during the second stage of labor in the primiparas].

OBJECTIVE

To observe the effects of the combined therapy of the auricular-point pressure at the free position and the unprotected perineal delivery technique during the 2nd stage of labor in the primiparas so as to improve the clinical delivery quality.

METHODS

A total of 146 primiparas who accepted the natural delivery willingly were collected. According to the visit sequence, they were divided into an observation group (72 cases) and a control group (74 cases). The free position and the unprotected perineal delivery were adopted in combination during the labor in both of the two groups. Additionally, in the observation group, the auricular-point pressure with semen vaccariae was intervened when entering the active phase. The points were pengqiang (TF), zigong (uterus), neishengzhiqi (TF), pizhixia (AT), shenmen (TF), jiaogan (AH), pi (CO) and wei (CO). Each point was pressed for 1 to 2 min each time, repeated once every 10 to 20 min until the end of the 2nd stage of labor. The episiotomy rate, perineal laceration degree, perineal pain degree, the duration of the 2nd labor stage, postpartum hemorrhage, postpartum urine retention and neonatal asphyxia rate were recorded and compared in the primiparas between the two groups.

RESULTS

The perineal laceration of the degree Ⅲ and Ⅳ did not occur in the two groups. Compared with the control group, the effect on the perineal laceration was better in the observation group (<0.05). The episiotomy rate was 5.6% (4/72) in the observation group, lower than that in the control group (<0.05). The total perineal laceration rate was 68.1% (48/72) in the observation group, similar to the control group (>0.05). In the observation group, the neonatal asphyxia rate was 1.4% (1/72), the postpartum hemorrhage 6.9% (5/72) and the incidence of urine retention 5.6% (4/72), all lower than 10.8% (8/74), 18.9% (14/74) and 17.6% (13/74) in the control group respectively (all <0.05). In the observation group, on the 1st, 2nd and 3rd days after labor, the perineal pain degree and the duration of the 2nd stage of labor were superior to the control group (all <0.001).

CONCLUSION

The combined therapy of the auricular-point pressure intervention at the free position and the unprotected perineal delivery technique effectively reduces the episiotomy rate and perineal laceration degree, relieves the perineal pain, reduces the neonatal asphyxia rate and improves the delivery quality during the 2nd stage of labor in the primiparas.
