The effect of non-pharmacological measures for pain relief in labor

INTERVENTION: Behavioural E02.190 E02.533 E02.779.483 Group A: 43 pregnant women at low risk in the active phase of labor will not receive assistance for pharmacological pain relief through the bath with hot water spray for 30 minutes. Group B: 43 pregnant women at low risk in the active phase of labor will not receive pharmacological assistance for the relief of perineal pain through exercise with the Swiss ball for 30 minutes; Group C: 42 pregnant women at low risk in the active phase of labor will not receive pharmacological assistance for the relief of pain through the sprinkler bath with hot water and perineal exercise Swiss ball for 30 minutes. CONDITION: C10.597.617.515 labor pain, Pain Measurement ; C10.597.617.515 PRIMARY OUTCOME: The study showed clinical and neuroendocrine reducing pain and stress to reduce pain and stress observed in clinical and neuro‐endocrine parturient after the use of non‐pharmacological interventions hot spray bath and perineal exercises with Swiss ball ; The note of pain and anxiety for pain scale, the evolution of obstetric data delivery by cervical dilation, progression of the fetus in the birth canal by the plan: To assess these outcomes, the data pre and post time control interventions will be evaluated DeLee, will be held assessment of fetal well‐being with the examination of cardiotocography, data related to maternal stress and adaptation to pain situation with measurement of blood pressure, pulse, respiration and dosages of the hormones cortisol, norepinephrine will be evaluated, epinephrine and salivary endorphin. Interventions will be offered randomly after randomization. SECONDARY OUTCOME: Secondary outcomes found showed no change in fetal well‐being through the use of interventions for pain relief, there was progression of obstetric parameters related to labor and development to delivery, reduction of labor time to maintain the fetal well‐being observed in the parameters of the test cardiotocography verified by evaluating the baseline fetal heart rate, presence of absence of transient acceleration and deceleration in fetal heart rate, progression in the evolution of obstetric parameters checked through the evaluation of cervical dilatation and descent of the fetal presenting plans DeLee conferred by vaginal touch, smoothing the pattern of uterine contractions observed by recording the examination of cardiotocography, shortening the labor verified by elapsed time between the intervention and the birth, favoring the normal delivery verified by type of delivery occurred INCLUSION CRITERIA: Voluntary without any clinical or obstetric disease; active phase of labor with efficient two or three in ten minutes uterine contractions and cervical dilatation minimum 3 cm; gestational age between 37 completed weeks to complete 42 weeks calculated by last menstrual period or the result of early ultrasound until the twentieth week of pregnancy; minimum age of 18 years old and maximum age of 55 years; pregnancy with single live fetus in cephalic presentation bent; Note greatest pain 5 on the pain scale
