摘要
Background: Spinal anesthesia (SA) is a preferred anesthetic technique for childbirth through caesarean section. It causes a sympathetic block responsible for low blood pressure which can be prevented or treated with vasopressors. Aim: This research aims to compare the effect of Noradrenaline with that of Ephedrine in the management of arterial hypotension caused by SA during Caesarean act. Study method: It was a cross-sectional study with two comparative settings which took place at the Teaching hospital of Parakou from April 15<sup>th</sup> to August 15<sup>th</sup> 2020. It included all parturients who underwent a caesarian act and received spinal anesthesia. To prevent hypotension two groups were formed. The first group parturient received Noradrenaline (10 γ) as prophylactic and the second group received Ephedrine (10 mg) before anesthesia. The main evaluation criteria were the time before the hypotension occurs and, the secondary endpoint was the number of hypotension episode. The two groups were compared using the usual statistical tests. The study received the approval of the Local Ethical committee of University of Parakou. Results: Two hundred and four parturients were compiled with 102 in each group. The mean age was 28.37 ± 6.15 years with extremes of 16 and 45 years. The main indications for Caesarean section were respectively iterative Caesarean section (46.57%) for scheduled Caesarean section and acute fetal distress (15.69%) for emergency Caesarean section. The incidence of hypotension was 38.24%. The mean delay of occurrence of hypotension was significantly longer in adrenaline group (19.90 min) than ephedrine group (12.53 min) with P = 0.001. According to the secondary endpoint the number of episodes of hypotension, number of tachycardia, and the total doses of each vasopressor were significantly lower in adrenaline group than in the ephedrine group. Conclusion: The use of Noradrenaline according to the established protocol demonstrated its efficiency compared with Ephedrine in the management of hypotension after spinal anesthesia.
