To compare the maternal and neonatal outcomes between perineal shaving and hair cutting in parturients on admission in labor
                Five hundred pregnant women with labor pain and no medical or obstetric complications were selected at random on admission to be assigned into two groups at Rajavithi Hospital from 1st November 2001 to 28th February 2002. Forty two women were excluded because of cesarean section. Two hundred and twenty-seven cases received perineal hair cutting and 231 cases received perineal shaving.
                The gestational age at delivery was statistically significant difference between those receiving perineal hair cutting (39.4 week) comparing with those receiving perineal shaving (39.1 week) (p < 0.05). There was no statistically significant difference in 2 groups for puerperal morbidity, perineal wound infection and dehiscence. There were no neonatal infection and puerperal infection in both groups, where as both accoucheurs and perineorrhaphy operators were more satisfied the perineal shaving group than the cutting group (p < 0.001).
                Perineal shaving or hair cutting on admission in labor had no statistical significant difference effect on the perineal wound infection and dehiscence, neonatal infection, puerperal morbidity and infection. Perineal warm packs are widely used during childbirth in the belief that they reduce perineal trauma and increase comfort during late second stage of labor. The aim of this study was to determine the effects of applying warm packs to the perineum on perineal trauma and maternal comfort during the late second stage of labor.
                A randomized controlled trial was undertaken. In the late second stage of labor, nulliparous women (n = 717) giving birth were randomly allocated to have warm packs (n = 360) applied to their perineum or to receive standard care (n = 357). Standard care was defined as any second-stage practice carried out by midwives that did not include the application of warm packs to the perineum. Analysis was on an intention-to-treat basis, and the primary outcome measures were requirement for perineal suturing and maternal comfort.
                The difference in the number of women who required suturing after birth was not significant. Women in the warm pack group had significantly fewer third- and fourth-degree tears and they had significantly lower perineal pain scores when giving birth and on "day 1" and "day 2" after the birth compared with the standard care group. At 3 months, they were significantly less likely to have urinary incontinence compared with women in the standard care group.
                The application of perineal warm packs in late second stage does not reduce the likelihood of nulliparous women requiring perineal suturing but significantly reduces third- and fourth-degree lacerations, pain during the birth and on days 1 and 2, and urinary incontinence. This simple, inexpensive practice should be incorporated into second stage labor care. To investigate the influence of the traditional hands-on versus the innovative hands-poised method on the risk of perineal trauma during vaginal delivery and on neonatal outcomes.
                In a prospective, randomized, multicenter study, 1,161 of 1,505 women giving birth at the Departments of Obstetrics and Gynecology of the University Hospital of Vienna and Semmelweis Women's Hospital, Vienna, between February and September 1999, were randomized into the trial. In the hands-on method, the left hand of the midwife puts pressure on the infant's head, and the right hand is placed against the perineum. In the hands-poised method, the midwife guides the parturient through the birth without touching the perineum, prepared to apply light pressure on the infant's head.
                One hundred eighty-seven of 574 women (32.5%) in the hands-on group and 180 of 502 women (35.8%) in the hands-poised group experienced perineal tears (P = .5). Sixteen women (2.7%) treated with the hands-on method developed third-degree perineal tears as compared with five women (0.9%) treated with the hands-poised method (P < .05). In the hands-on group, 103 women (17.9%) underwent episiotomy as compared with 51 cases (10.1%) in the hands-poised group (P < .01). No significant differences in neonatal outcomes were observed between the two groups.
                Our data suggest that a policy of hands-poised care is more suitable for preserving the perineum during birth and is a safe and effective birthing alternative for women. To determine the effects of perineal massage in the second stage of labour on perineal outcomes.
                Randomised controlled trial. Participants: At 36 weeks' gestation, women expecting normal birth of a singleton were asked to join the study. Women became eligible to be randomised in labour if they progressed to full dilatation of the cervix or 8 cm or more if nulliparous or 5 cm or more if multiparous. 1340 were randomised into the trial.
                Massage and stretching of the perineum during the second stage of labour with a water soluble lubricant.
                Primary outcomes: rates of intact perineum, episiotomies, and first, second, third, and fourth degree tears.
                pain at three and 10 days postpartum and pain, dyspareunia, resumption of sexual intercourse, and urinary and faecal incontinence and urgency three months postpartum.
                Rates of intact perineums, first and second degree tears, and episiotomies were similar in the massage and the control groups. There were fewer third degree tears in the massage group (12 (1.7%) v 23 (3.6%); absolute risk 2.11, relative risk 0.45; 95% confidence interval 0.23 to 0.93, P<0.04), though the trial was underpowered to measure this rarer outcome. Groups did not differ in any of the secondary outcomes at the three assessment points.
                The practice of perineal massage in labour does not increase the likelihood of an intact perineum or reduce the risk of pain, dyspareunia, or urinary and faecal problems. The aim of the study was to evaluate the effectiveness of perineal massage during pregnancy for the prevention of perineal trauma at birth. Study Design: Pregnant women with (n = 493) and without (n = 1034) a previous vaginal birth from 5 hospitals in the province of Québec, Canada, participated in this single-blind, randomized, controlled trial. All participants received oral and written information on the prevention of perineal trauma. Women in the experimental groups were requested to perform a 10-minute perineal massage daily from the 34th or 35th week of pregnancy until delivery.
                Among participants without a previous vaginal birth, 24.3% (100/411) from the perineal massage group and 15.1% (63/417) from the control group were delivered vaginally with an intact perineum, for a 9.2% absolute difference (95% confidence interval 3.8%-14.6%). The incidence of delivery with an intact perineum increased with compliance with regular practice of perineal massage (chi2 for trend 13.2, P = 0.0003). Among women with a previous vaginal birth, 34.9% (82/235) and 32.4% (78/241) in the massage and control groups, respectively, were delivered with an intact perineum, for an absolute difference of 2.5% (95% confidence interval -6.0% to 11.0%). There were no differences between the groups in the frequency of sutured vulvar and vaginal tears, women's sense of control, and satisfaction with the delivery experience.
                Perineal massage is an effective approach to increasing the chance of delivery with an intact perineum for women with a first vaginal delivery but not for women with a previous vaginal birth. To assess the efficacy of sweeping of membranes beyond 40 weeks of gestation in reducing the incidence of induction of labour, when induction was planned at 42 weeks.
                Prospective randomised controlled trial.
                A regional obstetric unit in Hong Kong.
                A total of 120 women with certain gestational age, determined by early pregnancy ultrasound scan, were recruited from 1st July, 1998 to 31st December, 1999. Sixty women were randomly allocated to sweeping of membranes and the other 60 women acted as control. The satisfaction for women allocated to sweeping of membranes was assessed by a questionnaire after the procedure. The two groups were assessed on intention-to-treat basis.
                The incidence of formal induction of labour was compared between the two groups. Possible complications of sweeping of membranes such as rupture of membranes, intrapartum infection, postpartum infection, and neonatal infection were also assessed. Maternal and perinatal outcomes were also assessed.
                The recruitment to delivery interval was significantly shorter among women who had sweeping of membranes (3.2 versus 4.2 days, P < 0.05). The incidence of induction of labour was comparable (35.5% versus 38%, RR 0.91, 95% CI 0.57 - 1.46). The incidences of caesarean section and assisted vaginal delivery were comparable. The incidences of premature rupture of membranes, intrapartum, and postpartum infection were comparable. The perinatal outcomes were also comparable between the two groups. Up to 70% of women found that this procedure was associated with significant discomfort. One third of these women complained of significant pain.
                Sweeping of membranes beyond 40 weeks does not reduce the need for formal induction of labour at 42 weeks. Although it is safe, the majority of women felt uncomfortable during the procedure. nan To compare the effect of two methods of perineal management used during spontaneous vaginal delivery on the prevalence of perineal pain reported at 10 days after birth.
                Randomised controlled trial.
                Two English maternity care units.
                5471 women who gave birth between December 1994 and December 1996.
                At the end of the second stage of labour women were allocated to either the 'hands on' method, in which the midwife's hands put pressure on the baby's head and support ('guard') the perineum; lateral flexion is then used to facilitate delivery of the shoulders, or the 'hands poised' method, in which the midwife keeps her hands poised, not touching the head or perineum, allowing spontaneous delivery of the shoulders.
                Perineal pain in the previous 24 hours reported by women in self-administered questionnaire 10 days after birth.
                Questionnaires were completed by 97% of women at 10 days after birth. 910 (34.1%) women in the 'hands poised' group reported pain in the previous 24 hours compared with 823 (31.1%) in the 'hands on' group (RR 1.10, 95% CI 1.01 to 1.18: absolute difference 3%, 0.5% to 5%, P = 0.02). The rate of episiotomy was significantly lower in the 'hands poised' group (RR 0.79, 99% CI 0.65 to 0.96, P = 0.008) but the rate of manual removal of placenta was significantly higher (RR 1.69, 99% CI 1.02 to 2.78; P = 0.008). There were no other statistically significant differences detected between the two methods.
                The reduction in pain observed in the 'hands on' group was statistically significant and the difference detected potentially affects a substantial number of women. These results provide evidence to enable individual women and health professionals to decide which perineal management is preferable. A controlled clinical trial was carried out to assess whether a birth room setting would influence the care of mothers and newborns. Of the 163 low-risk women enrolled, 49 (30%) manifested some prenatal risk and were excluded. The remaining 114 were allocated by strict alternation to a birth room or a conventional setting. Of the 56 women allocated to the birth room, 63% of the primiparas and 19% of the multiparas were later transferred. The numbers in the two settings who had oxytocin stimulation, epidural anesthesia, forceps delivery or cesarean section did not show statistically significant differences. The episiotomy rates were slightly lower in the birth room than in the conventional setting, and the rates of an intact perineum were higher in the birth room. Neither the Apgar scores nor the morbidity rates of the infants showed statistically significant differences related to the setting to which the mother had been allocated, although more infants from the conventional setting were admitted to a special care unit. Both "experimental" groups of women less often received routine perineal shaving, enemas or intravenous infusions than did an obstetrically similar nonexperimental comparison group. Despite the apparent inability in this setting for the birth room to influence the rate of major obstetric procedures (except for episiotomy) and outcomes, the authors believe that a birth room is desirable in tertiary care centres as well as in community hospitals.
There is insufficient evidence to recommend perineal shaving for women on admission in labour.
