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 compare the continuous knotless technique of perineal repair with the interrupted method after spontaneous vaginal birth

                Canadian Task Force Classification I.
                This study was undertaken in a university hospital with more than 2200 deliveries per year. The static population of this district includes a wide range of socioeconomic classes and is predominately white.
                From May 1 to November 19, 2003, 214 primiparous women with a second-degree perineal tear or episiotomy were randomly allocated to either the continuous knotless technique (CKT; n=107) or the interrupted technique (IT; n=107) suturing method.
                The interrupted technique (IT) involves placing 3 layers of sutures whereas the continuous knotless technique (CKT) involves reapproximating vaginal trauma, perineal muscles, and skin with a loose, continuous, nonlocking technique.
                The primary outcomes of the study were perineal pain (evaluated by visual analogue scale) at 48 hours and day 10 and dyspareunia 3 months after delivery. Secondary outcomes included suture removal, wound dehiscence, analgesia use up to 48 hours, and satisfaction with repair established at 3 and 12 months after childbirth. At day 10, 19 women had dropped out of the study. Significantly fewer women reported pain at 10 days with the CKT than with the IT (32.3% vs 60.4%; p<.001). Analgesia use up to 48 hours postpartum was less in the CKT group than in the IT group (33.6% vs 54.2%; p<.05). No difference was found in superficial dyspareunia at 3 months for the CKT versus the IT group.
                The use of a continuous knotless technique for perineal repair is associated with less short-term pain than techniques with interrupted sutures. Genital tract trauma after spontaneous vaginal childbirth is common, and evidence-based prevention measures have not been identified beyond minimizing the use of episiotomy. This study randomized 1211 healthy women in midwifery care at the University of New Mexico teaching hospital to 1 of 3 care measures late in the second stage of labor: 1) warm compresses to the perineal area, 2) massage with lubricant, or 3) no touching of the perineum until crowning of the infant's head. The purpose was to assess whether any of these measures was associated with lower levels of obstetric trauma. After each birth, the clinical midwife recorded demographic, clinical care, and outcome data, including the location and extent of any genital tract trauma. The frequency distribution of genital tract trauma was equal in all three groups. Individual women and their clinicians should decide whether to use these techniques on the basis of maternal comfort and other considerations. To evaluate the repair techniques of continuous and interrupted methods for episiotomy or perineal tears.
                A randomised controlled trial.
                The Hospital Universitario Principe de Asturias, a state hospital belonging to the community of Madrid.
                Four hundred forty-five women who had undergone vaginal deliveries with episiotomies or second-grade tearing of the perineum between September 2005 and July 2007.
                One group was repaired with continuous, nonlocking sutures involving the vagina, perineum, and subcutaneous tissues. The other group had continuous, locking sutures of the vagina, interrupted sutures in the perineal muscles, and interrupted transcutaneous sutures. The threads used for stitching were identical in both groups.
                The participants were questioned regarding the sensation of pain and the use of painkillers on the second and the tenth days, and 3 months postpartum.
                When comparing the group with continuous suture to the group with interrupted sutures, the differences included less repair time (1 minute; P= 0.017) and less suture material used (relative risk [RR], 3.2, 95% CI: 2.6-4.0). The comparison of pain on the second and tenth days, and 3 months postpartum were not statistically different between the two techniques (RR, 1.08, 95% CI: 0.74-1.57; RR, 0.96, 95% CI: 0.59-1.55; and RR, 0.68, 95% CI: 0.19-2.46, respectively).
                Although we did not demonstrate that one technique was better than the other in the incidence of pain in the short or long term, we showed that episiotomy and perineal tear repairs with continuous suturing were quicker and used less suture material without an increase in complication than interrupted suturing. The aim was to compare healing and perineal pain with the use of continuous and interrupted suture techniques in women after normal delivery. A randomized controlled trial was carried out at a hospital birth center in Itapecirica da Serra, Sao Paulo, Brazil. A total of 61 women participated with episiotomy or second degree perineal tear, allocated in two groups according to the continuous (n=31) or interrupted (n=30) suture techniques. The main outcomes evaluated were edema, ecchymosis, hyperemia, secretion, dehiscence, fibrosis, frequency and degree of pain (evaluated by numerical scale from 1 to 10). Data were collected during hospitalization and after discharge (four and 41 days after birth). Healing occurred by first intention in 100% of cases in both suture techniques. There were no statistically significant differences for the occurrence of morbidities, except for perineal pain due to palpation at four days after delivery, which was more frequent among women with interrupted suture. Trauma to the perineum is a serious and frequent problem after childbirth, with about 350000 women each year in the UK needing sutures for perineal injury after spontaneous vaginal delivery, and many millions more worldwide. We compared the continuous technique of perineal repair with the interrupted method, and the more rapidly absorbed polyglactin 910 suture material with the standard polyglactin 910 material.
                1542 women who had a spontaneous vaginal delivery with a second-degree perineal tear or episiotomy were randomly allocated to either the continuous (n=771) or interrupted (771) suturing method, and to either the more rapidly absorbed polyglactin 910 suture material (772) or standard polyglactin 910 material (770). Primary outcomes were pain 10 days after delivery and superficial dyspareunia 3 months postpartum. Analysis was by intention to treat.
                At day 10, three women had dropped out of the study. Significantly fewer women reported pain at 10 days with the continuous technique than with the interrupted method (204/770 [26.5%] vs 338/769 [44.0%], odds ratio 0.47, 95% CI 0.38-0.58, p<0.0001). Occurrence of pain did not differ significantly between groups assigned the more rapidly absorbed material or standard material (256/769 [33.3%] vs 286/770 [37.1%], 0.84, 0.68-1.04, p=0.10). Women reported no difference in superficial dyspareunia at 3 months for the continuous vs the interrupted method (98/581 [16.9%] vs 102/593 [17.2%], 0.98, 0.72-1.33, p=0.88) or the more rapidly absorbed versus standard material (105/586 [17.9%] vs 95/588 [16.2%], 1.13, 0.84-1.54, p=0.42). Suture removal was done less with the more rapidly absorbed material than with standard suture material (22/769 [3%] vs 98/770 [13%], p<0.0001), and with the continuous versus interrupted method (24/770 [3%] vs 96/769 [12%], p<0.0001).
                A simple and widely practicable continuous repair technique can prevent one woman in six from having pain at 10 days. Also, the more rapidly absorbed polyglactin 910 material obviates need for suture removal up to 3 months postpartum for one in ten women sutured.
The use of warm compresses on the perineum is associated with a decreased occurrence of perineal trauma. The procedure has shown to be acceptable to women and midwives. This procedure may therefore be offered to women.
