The Effect of Hands-off and Hands-on Methods on Perineal Status

Perineal damage is one of the traumas most frequently suffered by women during deliver/. There are several techniques aimed at reducing the perineal damage. The present study is aimed at determining and comparing the frequency and degree of perineal rupture in hands-off and hands-on techniques of protecting perinea during labor. Method and Materials: This blind clinical trial (with the CI of 95% and test power of 80%) involved 187 women who, after signing their informed consent, were divided into the hands-off (n= 98) and hands-on (n=89) groups through random allocation. In the experimental (hands-off) method, the midwife guides the parturient and observes the process of labor without touching the perineum or the head. In the control (hands-on) group, the midwife protects the infantʹs head using Ringen maneuver. The data were analyzed in SPSS using chi-square and Fisherʹs exact test. Results: The result showed that the undamaged perinea in the hands-off group was 44.9%, versus 10% in the hands-on group, where the difference was statistically significant (P < 0.0001). Perineal laceration was 51% in the hands-off group and 47.2% in the hands-on group but the difference between the two groups was not significant (p = 0.55). Most ruptures were of the first-degree type (50% in the hands-off and 64.3% in the hands-on group). In the hands-off group, 3.1% underwent episiotomy as compared with 75.3% in the hands-on group. Conclusion: The results suggest that a policy of hands-off technique in protecting perinea can be safe and efficient technique and can be an alternative method in perineal protection during labor.
