| Abstract | |
The third stage of labor starts after expulsion of the fetus and ends with the detachment of the placenta. The post-partum blood loss is directly associated to the time of placental detachment and uterine contractility. The active management recommendations for the third stage of labor, issued by ICM/FIGO and WHO, are based on scientific evidence concerning its potential to reduce maternal morbidity and mortality. It encompasses the following interventions: prophylactic administration of oxytocins, after delivery of the baby; early clamping and cutting of the umbilical cord; controlled traction of the cord and massage of the uterine fundus, with the purpose of reducing post-partum blood loss. Objective: to identify the way of managing the third clinical stage of a normal delivery in a teaching maternity hospital and to analyze the obstetric results in the immediate puerperium. Methodology: The sample consisted of 142 women in labor. Data collection was performed by non-participating observation, backed-up by a form previously tested in a pilot study. Results: Afterbirth was spontaneous in 98.6% of the deliveries, with an average duration of 8.79±7.48 minutes. Early clamping and cutting of the umbilical cord were the most frequently performed intervention (93.7%), followed by controlled traction of the cord (87.3%), massage of the uterine fundus (70.4%); early contact (52.8%); early breastfeeding (34.5%); use of ergotamine (3.5%). Oxytocin was used only as an additional therapeutic after delivery (73.9%), at a mean dosage of 9.48±9.47 IU. The following complications were identified: medium-amount bleeding (15.5%); curage (4.2%), and large-amount bleeding (3.5%). No statistically significant association was found (Fisher\'s exact test) between the components of the active management and the occurrence of medium- or large-amount bleeding. A statistically significant association between fetal weight and post-partum bleeding (p=0.043), and an almost significant association between Caucasian ethnicity and post-partum bleeding (p=0.074) were identified. No association with other independent variables was found. Final considerations: Although there is scientific evidence indicating that the active management in the third stage of labor is effective, our results reveal that resistance to adopt it persists and that there was no adhesion to many of its components in the studied institution, where a \"mixed\" management is done (components of the active management and of the passive management). The frequency of complications and their severity were low. We stress the need for further studies on this subject, especially regarding an objective evaluation of blood loss and its clinical repercussions during the puerperium. (AU) | |
