Non-pharmacological Resources in Assisting Labor

Application of Non-pharmacological Resources in Assisting Labor: Randomized Controlled Trial

The proposed project will be conducted to evaluate the influence of application resources associated with non-pharmacological during labor for pain relief and accelerated phase of expansion. Although mothers' access to resources for non-pharmacological pain relief during labor is recommended, is not seen as the application of routine obstetric practice, although it has been demonstrated benefits and scientific evidence with your application. It is believed that the implementation of associated application of non-pharmacological resources in assisting the labor can be introduced into daily practice in various hospitals in the country, minimizing pain and favoring the shorter duration of labor, decrease in use of painkillers and inductors, resulting in a reduction of complications, improves the comfort of the mother making her birth experience more satisfying and rewarding, being assisted with security and trained by multidisciplinary teams.

Study Overview

• Status: Completed
• Conditions: Labour Pain
• Intervention / Treatment: Other: Routine care; Other: Non-pharmacological resources

Detailed Description

The current model of care delivery has demanded a technical-assistance approach that prioritizes the quality of care, as indissolubly concerns the employment of technology, knowledge, the centrality of dialogue between professionals and patients and individualized choice resources deemed suitable for safe delivery. Seeking to implement a less interventionist care with evidence-based practice and greater incentive to vaginal delivery, the programs were created humanization of labor and birth, with the use of various non-pharmacological resources. This study aimed to evaluate the effectiveness of the combination of non-pharmacological resources during the dilation in relieving the pain of the mothers. The research will be of type randomized controlled trial, consisting of low-risk primigravidae admitted at the Reference Center for Women's Health in Ribeirão Preto. The mothers will be distributed in two groups (intervention protocol features non-drug) and Control (routine maternity) and will be evaluated before and after application of each resource, and the control group in the same time according to cervical dilation. Evaluation will be conducted by a visual analog scale and / or facial pain and pain location diagram and postpartum will be applied a validated questionnaire Experience and Satisfaction with childbirth. After collecting the data, the groups are statistically analyzed using the linear regression model with mixed effects (fixed and random), taking into account a value of p <0.05 to obtain the statistical significance of 5%.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Control Group; Pregnant women who receive assistance from the routine CRSM MATER care, not being assisted by the physiotherapist, but that will be evaluated at the same time in the intervention group.	Other: Routine care; Routine care of the institution performed by the staff, without the presence of the researcher that included offering a balanced meal, continuous support with the presence of a partner or family throughout labor, use of oxytocin when prescribed by the staff, use of drug analgesia when requested by the patient.
Experimental: Intervention Group; Pregnant women who receive the application the combination of non-pharmacological resources according to cervical dilation: pelvic mobility , lumbosacral massage and warm shower.	Other: Non-pharmacological resources; A sequence of non-pharmacological resources were applied to the patient by the researcher according to uterine cervical dilation, as follows: Pelvic mobility on the exercise ball oriented and accompanied by the researcher for 40 minutes;; Lumbosacral massage for a period of 40 minutes, when dilation was between 5 and 6 cm. During the procedure, the woman in labor was allowed to freely choose the most comfortable position; and,; Warm shower with the water flow directed to the lower-back of the woman in labor, for 40 minutes, when uterine cervical dilation was equal to or higher than 7cm.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Pain Relief	The Visual Analogue Scale - VAS - was used to measure the intensity of the pain described by the patients during the study. The patient was requested do mark a dot in a straight line, measuring 100mm, being a 0 (Zero) no pain and 100 the most intense pain. The researcher then would measure the estimated pain intensity in millimeters. The pain intensity was measured in all three phases before and after each procedure assigned to each group. The phases and their respective procedures were: Phase I: 4-5cm of cervical dilation (pelvic mobility in exercise ball); Phase II: 5-6cm of cervical dilation (lumbosacral massage); Phase III: 7cm or higher cervical dilation (warm shower)	ten hours

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Evolution of Labor	Amount of minutes, from admission to labor.	10 hours
Moment That Women Requested Analgesia During the Active Phase of Labor	Mean uterine cervical dilation at the moment the patient requested analgesia for pain relief. Data obtained from medical record	10 hours
Number of Women Who Received Pharmacological Analgesia	Determine the number of women who where submitted to pharmacological analgesia, either prescribed by the attending physician ou requested by the patient herself.	10 hours
Type of Delivery	Type of delivery at the end of the active phase of labor.	10 hours
Number of Participants Whose Neonates Had:	Number and type of neonatal complications as reported in medical chart	10 hours
Number of Participants With:	Number and type of maternal complications as reported in medical chart	10 hours
