Objective: Neuroaxial analgesia is the most effective technique to treat labor pain, however, there are still concerns regarding the undesirable effects. Objective: To evaluate the association between epidural analgesia maintained by programmed intermittent epidural boluses (PEIB) and maternal perinatal complications.  Materials and methods: Observational, analytical study of Cohort type in pregnant women between 18 and 35 years, in labor with cervical dilation of 4 centimeters or more, grouped in two cohorts according to administration or not of epidural analgesia: In pregnant women of Group A, administered bolus epidural analgesia, with maintenance by BEIP with bupivacaine 0.0625% and fentanyl 25 ug in 10cc every 60 minutes; in pregnant women of group B, epidural analgesia was not administered. Results: The duration of the dilation and expulsion period was longer in the group...

To the Editor, Spinal anesthesia is considered the technique of choice in most cesareans, with hypotension being the most common adverse effect. The symptoms that frequently accompany hypotension are: nausea, vomiting, dyspnea and neonatal deleterious effects, among them, low Apgar score and acidosis in cord blood gas analysis1. The question is what is the most effective strategy to prevent and treat hypotension secondary to spinal anesthesia for caesarean section? It is crucial in obstetric anesthesia and the response is related to the physiological events that lead to hypotension. For many years the administration of a volume of crystalloids prior to the placement of spinal anesthesia was mandatory, just as ephedrine was considered the vasopressor of choice to treat such hypotension. The available scientific evidence shows us the opposite2.
