FETAL IMPACT WITH THE USE OF PHENYLEPHRINE INTRAVENOUS INFUSION USED AS PROPHYLAXIS OF ARTERIAL HYPOTENSION AFTER INTRADURAL ANESTHESIA AT ELECTIVE ISSUES
Background and goal 
The objective of this study was to assess the fetal repercussion, both in the Apgar test and in cord blood gas analysis, of the use of continuous intravenous infusion of phenylephrine used as prophylaxis for hypotension after intradural anesthesia in elective cesarean
Material and Methods
We performed a prospective study including all elective cesarean performed at the obstetrics service of the Miguel Servet University Hospital from November 2012 to March 2015. We excluded the non-acceptance of participation in the study, the presence of uterine dynamics or the suspicion of maternal-fetal pathology. 105 patients were included into the study.
All patients underwent an intradural anesthesia with 0.5% hyperbaric bupivacaine and doses according to the size (<155cms-10mg, 155-165-11mg,> 165-12mg)
All newborns were submitted to an apgar test at 5 minutes of life, as well as  arterial and venous blood from umbilical cord was taken  for determination of gasometry.

We made a comparative analysis evaluating  pre and post intradural anesthesia data according if patients  were administered a continuous intravenous infusion of phenylephrine(2mcg/Kg/min) (53 patients)or not( 52 patients). The patients were randomly assigned to each group.
To correlate different variables we used the chi square of Pearson or Fisher test for discrete variables and t-student or U Mann-Whitney test for continuous variables. Significance at  p<0.05

Results and Conclusions
Prophylaxis of arterial hypotension with phenylephrine in intravenous infusion at 2 mcg / kg / min, did not present a significant impact at the fetal level, assessed by Apgar test and cordometric gasometry.
