Efficacy of "optimal hydration" during labor: HYDRATA study protocol for a randomized clinical trial.

There is a lack of consensus in the international scientific community with respect to the most suitable hydration strategies when attending nulliparous women during low-risk births. This paper describes the protocol for a randomized controlled trial to compare two hydration strategies and their influence on maternal and neonatal morbidity. The study population consists of nulliparous women admitted to the obstetrics department of a University Hospital. The women are being randomized into two groups: the "optimal hydration" group, which will be guaranteed 300 ml/hr liquids (crystalloids and bottled mineral water) with a minimum diuresis of 35 ml/hr; and the "variability in hydration" group, which will receive intravenous (alternating normal saline, Ringer's lactate solution, glucose, or Voluven®) and clear (bottled mineral water or isotonic drinks [Aquarius®]) liquids, without any established perfusion rate, and without established minimum diuresis. Outcomes for mothers include duration of labor, cesarean section, fever, and dehydration. Outcomes for newborns are respiratory distress, hypoglycemia, hyponatremia, jaundice, weight loss over 48 hr, and breastfeeding difficulties. Analysis will be per-protocol. Administering optimal hydration may improve health and safety for mothers and their newborn and reduce maternal and neonatal morbidity. The study is registered at www.clinicaltrials.gov. The project received funding by the Ministry of Health of Spain and is approved by the Research Ethics Committee.

Perineal repair of media-lateral episiotomies and 2nd degree tears by midwives: A randomised controlled trial comparing three suture techniques.

BACKGROUND: Perineal trauma pain is associated with perineal repair and its subsequent healing. New evidence is required concerning perineal repair techniques that cause less pain and favour healing. OBJECTIVE: To compare three perineal repair suturing techniques after episiotomy or second degree tearing during a normal birth with respect to reducing pain and improving the perineal healing process. DESIGN: A randomised controlled trial. SETTING: A large public university hospital in Madrid, Spain. PARTICIPANTS: Full term pregnant women older than 18 years-of-age, who required perineal repair after episiotomy or second degree tearing and were attended for normal birth by midwives. METHODS: One hundred and eighty-three women were randomly assigned to three groups: the Continuous Suture Group (n = 58), Interrupted Cutaneous Suture Group (n = 53), or the Interrupted Subcutaneous Suture Group (n = 57). The study participants and data collectors were blinded to group allocations. Principal outcome: perineal pain 10 days after birth. Other outcomes: short (2 and 48 h) and long term (3 and 6 months) perineal pain after birth; short term healing; suture time. RESULTS: At 10 days postpartum, the presence of spontaneous pain, pain when walking or moving in bed, was almost nonexistent in the 3 suture groups. The median (P25-P75) perineal pain on palpation was similar in the 3 groups, with values of 2 (1-4) in the Continuous Suture Group, 3 (2-5) in the Interrupted Cutaneous Suture Group and 2 (1-4) in the Interrupted Subcutaneous Suture Group; also were similar the perineal pain on sitting: 1 (0-3) in the Continuous Suture Group, 1 (0-2) in the Interrupted Cutaneous Suture Group and 1 (0-3) in the Interrupted Subcutaneous Suture Group. There were no statistically significant differences between the groups. Pain measurements throughout the follow-up period only showed statistically significant differences in 2 out of 22 evaluations: pain when sitting 48 h after birth and spontaneous pain at 3 months. The mean times (standard deviation) to carry out suturing were 12.86 (4.9) minutes in the Continuous Suture Group, 13.54 (5.6) in the Interrupted Cutaneous Suture Group, and 15.59 (6.9) minutes in the Interrupted Subcutaneous Suture Group (p < 0.05). CONCLUSIONS: The three suturing methods described for perineal repair after episiotomy or second degree tearing after normal birth are comparable with respect to short, medium and long term perineal pain and the healing process. Use of the continuous suturing technique involved less time than interrupted suture methods. Tweetable abstract: proper the suturing methods for perineal repair after episiotomy or second degree tearing prevent postpartum perineal pain.

The development and validation of a new postpartum sexual function and dyspareunia assessment tool: The Carol Scale.

OBJECTIVE: The aim is to develop a new tool to evaluate postpartum sexual function and dyspareunia which will facilitate better evaluation of perineal pain in woman after vaginal delivery. DESIGN: The development and validation of the Carol Postpartum Sexual Function and Dyspareunia Assessment Scale. SETTING: The Obstetrics and Gynecology Service of a University Hospital in central Spain. PARTICIPANTS: 102 women after being attended for vaginal birth, and 5 midwife assessors. FINDINGS: 81women reinitiated sexual activity (with vaginal intercourse) during the first three months postpartum. The Carol Postpartum Sexual Function and Dyspareunia Assessment Scale (Carol Scale) was internally reliable with a Cronbach-α value of 0.79 (95%CI0.72-0.85). Cronbach-α coefficients for Carol Scale domains were: preparation for the sexual activity 0.69 (95%CI0.55-0.79), pain or discomfort on caressing the vulval area 0.86 (95%CI0.79-0.91), pain or discomfort related to vaginal intercourse 0.93 (95%CI0.90-0.95) and pain or discomfort after vaginal intercourse 0.86 (95%CI0.78-0.91). CONCLUSIONS: The Carol Postpartum Sexual Function and Dyspareunia Assessment Scale is valid and reliable for measuring sexual function and postpartum dyspareunia in women after being attended for vaginal birth. IMPLICATIONS FOR PRACTICE: The Carol Scale could be used both clinically and in research to improve the quality of care for the mother after childbirth. The scale could help to identify problems in the reinitiation of postpartum sexual activity and, therefore, could contribute to widening the clinical information about these women and help in decision making.
