Abstract
Pain during labor may elicit different responses that can be detrimental both to the mother and the fetus. Among the different methods used to relieve pain during childbirth, neuraxial analgesia has proven to be the most effective. The epidural technique and the combined spinal-epidural are the most common techniques for administrating neuraxial analgesia. Several studies have analyzed the adverse reactions of these techniques, by comparing their effects on uteroplacental perfusion measured by uterine contractions, fetal heart rate and the need to perform an emergency cesarean delivery due to these alterations. Comparing the results in these studies, it was demonstrated that, even though patients that had received a combined spinal-epidural presented greater fetal heart rate alterations, this did not increase perinatal complications significantly. These alterations have shown to be transient and, if recognized and treated promptly, do not increase maternal or fetal morbidity and mortality.
