Objectives:

to demonstrate the effect of adrenaline infusion in relation to noradrenaline for the purpose of preventing maternal hypotension post intradural anesthesia.

Methods:

a total of 114 people, a sample of 46 patients, are distributed in 2 distinct group: A (noradrenaline) and B (adrenaline) at a dose of 0.02 pg/kg/ min. Mean of continuous variables was measured and Shapiro - Wilk normality test was applied. Student's T was applied for the means and Mann-Whitney U for the medians. The frequency was determined for nomina variables.

Results:

the age was 32 to 33 years, with a significant heartbeat in T3 and T4 for group B, p value 0.045 and 0.000. No significant changes in blood pressure or APGAR scores. Side effects are the presence of headache possibly related to the use of oxytocin. 18 and 16 patients did not present hypotension with chi square of 0.89 Total volume of crystalloids from 650 ml to 700 ml in both groups A and B. The reference cost was 0.9 bolivianos

Conclusions:

adrenaline is a suggestive vasopressor, without alterations in maternal heartbeat, but with greater control than noradrenaline, and with a similar action on mean arterial pressure in both groups.
