Influence of continuous support offered by Doula on hormone release in women in labor

INTERVENTION: SP2.006.027.023 The intervention will consist of maintenance alongside the parturient, providing the support in three different dimensions: physical comfort (massage in the lumbosacral region and in the upper and lower limbs, with slip, kneading and pressure techniques, offered with vegetable massage oil certified by ANVISA , hydrotherapy with a shower bath at temperature controlled by the parturient threshold, between 34 and 38 C, warm water compresses between 38 and 40 ºC in the lumbosacral region and the lower belly, use of the Swiss ball to favor the possibility of vertical rest with parturient seated with trunk leaning forward and pillow support on the stretcher, pelvic mobility with anteversion and pelvic retroversion and circumference, comforting touches, ambulation and changes of posture, according to the preference of the parturients, being able to adopt left lateral decubitus, four supports, standing, kneeling or squatting during contractions); emotional support (continuous empathic and welcoming presence, providing encouragement and security, seeking to assist the parturient in identifying their emotions and bodily sensations); and information support (information on the evolution of labor, ensuring the normality of the process, responding to the main doubts and favoring communication between the mother and the child). In relation to the control group, the parturients will not receive any additional intervention to those performed by the medical and technical team, that is, they will only be with their escort of choice without receiving continuous support from a Doula. CONDITION: Pregnancy; Humanizing Delivery. U00‐U99 PRIMARY OUTCOME: Expected results: greater satisfaction with the experience of labor; increase in oxytocin level in relation to the control group; increase in the serotonin level in relation to the control group; increase in the level of beta‐endorphin in relation to the control group; decrease in cortisol level in relation to the control group; decrease in the level of adrenaline and noradrenaline in relation to the control group SECONDARY OUTCOME: Doula's continued support is expected to have a positive impact on women's perception of care received and delivery, on obstetric and neonatal outcomes, as well as on endogenous hormone release and reduced levels of stress, since reduced levels of cortisol are associated with an adequate production of the hormones involved in parturition. INCLUSION CRITERIA: Parturients hospitalized for childbirth care at centro de referência da saúde da mulher; maternal age greater than or equal to 18 years; primigestas; single term pregnancy; hospital admission at the beginning of the active phase between 4 to 6 cm.
