Abstract: BACKGROUND: Having considered the physiologic challenges during pregnancy, scientists have searched for different delivery methods with minimal medical intervention. The use of water immersion by women for relaxing during labor is being used worldwide. We aimed to evaluate the controversies surrounding water birth and to find out the interest of Iranian women in this delivery method. METHODS: In a randomized clinical trial, 106 pregnant women were assigned to control and experimental groups. The experimental group underwent the labor and delivery in standardized warm water pools. The control group gave birth by conventional delivery method at the hospital. A questionnaire was completed during the labor for women in both control and experimental groups including the method of delivery; labor length; use of different drugs such as analgesics, opiates, antispasmodic, and oxytocin; use of episiotomy, and newborn's Apgar score and weight. RESULTS: Totally, 53 cases and 53 controls with the mean age of 26.4+/-5.9 and 27.1+/-5.9 years, respectively, completed the study. Women in the control group required oxytocin, antispasmodics, opiates, and analgesics more frequently than those in the experimental group (P<0.001). Meanwhile, the active phase and the third stage of labor were shorter experimental group by 72 and 1.3 minutes, respectively (P<0.004, and P<0.04). All the participants in the experimental group gave birth naturally, whereas only 79.2 Article Published Date : Sep 01, 2009

Abstract: BACKGROUND: Our purpose was to assess benefits and possible disadvantages of water births and to compare maternal and neonatal outcomes with normal vaginal deliveries. METHODS: This case-controlled study was carried out between January 2000 and July 2001. A total of 140 women who wanted water births were enrolled into the study. Our analysis was restricted to a sample of women with a gestational age>37 weeks, a normal sized foetus, a reactive admission cardiotocography, drainage of clear amniotic fluid (if the membranes were already ruptured) and a pregnancy with cephalic presentation. Women with medical or obstetric risk factors were excluded. 140 controls were selected from the delivery database as the next parity-matched normal spontaneous vaginal delivery. RESULTS: A statistically significant lower rate of episiotomies (p = 0.0001) and vaginal trauma (p = 0.03) was detected in the group assigned to water birth, whereas the frequency of perineal tears and labial trauma remained similar in both groups (p>0.05). A statistically significant decrease in the use of medical analgesia (p = 0.0001) and oxytocin (p = 0.002) was observed in women who had water births. A trend towards a reduction of the length of the first stage of labour was only observed in primiparous women bearing in water, but this reduction did not reach statistically significance (p>0.05). Manual placenta removal (p = 0.017), severe postpartum haemorrhage (blood loss>500 ml; p = 0.002) and maternal infection rate (p = 0.03) were statistically significant lower in women who delivered in water. When analysing the postpartum haemoglobin, no statistically significant differences could be observed between the two groups (p>0.05). No statistically significant differences were detected for neonatal parameters (p>0.05) between women who had had water births and those choosing conventional vaginal delivery.

Abstract Title: A retrospective comparison of water births and conventional vaginal deliveries. Abstract Source: Eur J Obstet Gynecol Reprod Biol. 2000 Jul;91(1):15-20. PMID: 10817872 Abstract Author(s): C M Otigbah, M K Dhanjal, G Harmsworth, T Chard Article Affiliation: Department of Obstetrics and Gynaecology, Homerton Hospital, London, UK. Abstract: The aim of this study was to document the practice of water births and compare their outcome and safety with normal vaginal deliveries. A retrospective case-control study was conducted over a five year period from 1989 to 1994 at the Maternity Unit, Rochford Hospital, Southend, UK. Three hundred and one women electing for water births were compared with the same number of age and parity matched low risk women having conventional vaginal deliveries. Length of labour; analgesia requirements; apgar scores; maternal complications including perineal trauma, postpartum haemorrhages, infections; fetal and neonatal complications including shoulder dystocias; admissions to the Special Care Baby Unit, and infections were noted. Primigravidae having water births had shorter first and second stages of labour compared with controls (P<0.05 and P<0.005 respectively), reducing the total time spent in labour by 90 min (95% confidence interval 31 to 148). All women having water births had reduced analgesia requirements. No analgesia was required by 38% (95% confidence interval 23.5 to 36.3, P<0.0001) and 1.3% requested opiates compared to 56% of the controls (95% confidence interval 46. 3 to 58.1, P<0.0001). Primigravidae having water births had less perineal trauma (P<0.05). Overall the episiotomy rate was 5 times greater in the control group (95% confidence interval 15 to 26.2, P<0.0001), but more women having water births had perineal tears (95% confidence interval 6.6 to 22.6, P<0.001). There were twice as many third degree tears, post partum haemorrhages and admissions to the Special Care Baby Unit in the controls, although these differences were not significant. Apgar scores were comparable in both groups. There were no neonatal infections or neonatal deaths in the study. This study suffers from many of the methodological problems inherent in investigation of uncommon modes of delivery. However, we conclude that water births in low risk women delivered by experienced professionals are as safe as normal vaginal deliveries. Labouring and delivering in water is associated with a reduction in length of labour and perineal trauma for primigravidae, and a reduction in analgesia requirements for all women.
