The Maternal and Perinatal Outcomes Associated With the Use of Non-pharmacological in Labor

2021年5月23日 更新者:Alessandra Cristina Marcolin、University of Sao Paulo

Evaluation of Maternal and Perinatal Outcomes Associated With the Use of Non-pharmacological in Parturients in Active Phase of Labor

Although there are studies that investigated the use of non-pharmacological pain relief and correction of dystocia during labor, there are few randomized controlled trials, especially related to combined protocols that use such resources. The use of combined protocols could potentiate the effects of resource use alone, evidencing the need for more studies related to the topic, as well as the effects of these methods on maternal and perinatal outcomes. In order to verify the effect of these methods in various stages of labor, childbirth and immediately becomes necessary to conduct a randomized controlled trial well-designed and adequate sample size that can make the future systematic reviews that can definitely conclude about the potential effectiveness of protocols that use combined resources to non-pharmacological pain relief in labor. Aim of our study is to evaluate the effects of a protocol of non-pharmacological resources on pain of pregnant women in the active phase of cervical dilatation and compared with controls.

研究概览

详细说明

Labor is a natural physiologic process triggered by mechanical and hormonal events that promote uterine contractions. Several non-pharmacological resources can be used during labor, such as relaxation techniques and ongoing support, maternal mobility, walking, breathing exercises, massage, Swiss ball, stool, shower, whirlpool and application of transcutaneous electrical stimulation (ENT .) Despite the role of physiotherapy in labor is not an established practice in public hospitals, it is expected that with the evidence of the benefits of non-pharmacological resources at this time, managers and health professionals validate the importance of interdisciplinary care in pregnancy - postpartum. The aim of this study is to evaluate the effects of resources on non-pharmacological pain of mothers in the active phase of cervical dilatation when compared to controls. This research is a randomized, controlled clinical study that includes pregnant women randomly assigned to two groups: Intervention Group (IG) women who will use the following sequence features: ambulation (with cervical dilatation of 4 to 5 cm), alternating stance associated with ENT (cervical dilatation from 6 to 7 cm) and a shower (with dilation> 7 cm) for 40 minutes each resource; Control Group (CG) women who will not use any physical therapy resource, are subject only to routine procedures of maternity care . For pain assessment will use the Visual Analogue Scale - VAS and the body diagram of the location and spatial distribution of pain. Results are presented in tables and graphs made to better understand the comparisons between the control and intervention. To compare maternal morbidity, obstetric and neonatal between groups will be used Fisher's exact test or chi-square.

参与者组/臂
干预/治疗
有源比较器:Control
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.
实验性的:Intervention Group
Experimental: Intervention Group Pregnant women who receive the application the combination of non-pharmacological resources according to cervical dilation: Walking (with cervical dilation between 4 and 5 cm) Alternating stance associated with ENT (cervical dilatation from 6 to 7 cm) Shower (with dilation> 7 cm);

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:

  • Walking (with cervical dilation between 4 and 5 cm)
  • Alternating stance associated with ENT (cervical dilatation from 6 to 7 cm)
  • Shower (with dilation> 7 cm);

研究衡量的是什么?

主要结果指标

结果测量
措施说明
大体时间
Number of Participants Who Requested Analgesia During the Active Phase of Childbirth
大体时间:10 hours
Average uterine cervical dilation of the patient who requested analgesia for pain relief. Data captured from the medical record by the partograph.
10 hours
The Moment in Centimeters That Women Requested Analgesia During the Active Phase of Childbirth, Analyzed by Cevical Dilation.
大体时间:10 hours

Moment when a patient requested analgesia for pain relief. Data captured from the medical record by the partograph.

A partogram was used, which is a printed document and allows the registration of all procedures and complications that occurred during labor, showing the conditions of the parturient and the fetus during this phase. This information is noted on a graph that makes it possible to assess all labor and duration. The doctor filled out the partograph and assessed the patient during labor, and she did not know which group belonged to the patient

10 hours
Average Duration of the Expulsive Period When Compared to Groups
大体时间:Starts with 10 centimeters of dilation until delivery
Assess the duration of the expulsion period and compare between groups
Starts with 10 centimeters of dilation until delivery
Types of Dystocia (Functional, Secondary Stop of Dilation and Fetal Offspring) Between Groups
大体时间:10 hours

Analyze and compare between the groups the types of dystocia.

Dystocia:

b.1) Functional dystocia was considered when cervical dilation increased progressively, but with a speed less than 1 centimeter per hour; b.2) Secondary stop of the dilation was considered when there were 2 vaginal touches with the same cervical dilation in an interval of at least two hours, without being total.

b.3) Secondary descent stop was considered when, with complete dilation of the uterine cervix, the same height of fetal descent was found in two successive touches with an interval of one hour (Protocol Royal College of Obstetricians and Gynecologists, 2012).

10 hours
Admission Numbers to a Neonatal Intensive Care Unit Between Groups.
大体时间:10 hours
Consider and compare neonatal admission to an intensive care unit between groups, attracted by the partogram
10 hours
Number of Newborns With Apgar Scores of 1 and 5 Minutes, Less Than or Greater Than 7.
大体时间:10 hours

Analyze and compare Apgar scores of the 1-min >7 and 5-min >7, between groups. The APGAR score reflects the degree of fetal maturity and predicts healthy child development. It is a scale that can vary from 0 to 10, which 0 is a bad vitality and 10 is an excellent score. When the APGAR score is below 7, especially in the fifth minute, it is a warning sign to give special attention to the newborn.

Newborns who have an Apgar in the first minute greater than 7, demonstrate good birth conditions.
