Objective:

To assess the venous gases in the umbilical cord, in the newborns of healthy mothers, obtained by cesarean section, using two different regional anesthesia techniques.

Methods:

With previous authorization from the ethics committee, a replicative, observational, transversal, comparative-analytical, non-probabilistic sample study was carried out during November 2016 to January 2017 in obstetric patients from Hospital Universitario “Dr. José Eleuterio González”. 42 patients were included and classified into two groups according to the election of the anesthesiologist: the first group received epidural anesthesia, the second group received spinal anesthesia with epidural catheter.

Results:

The group which received subarachnoid anesthesia presented major events of hypotension after 15 minutes 80.95% (p= 0.0407), ODD (4.675), and greater tendency to stay more time hypotensive (p = 0.5195), ODD (1,625). Therefore the newborn babies of this group had pH significantly more under 7.19, ± 0.26, (P = 0.0481). No relevant differences were found on the Apgar scale at birth (p = 0.9999).

Conclusions:

In our study findings suggest that subarachnoidal anesthesia products from mothers who were applied have pH levels acidemia, secondary to pharmacological sympathectomy-compatible, without impact to the newborn.
