Post-spinal hypotension at cesarean section: the denial of evidence

Post-spinal hypotension at cesarean section appears difficult to prevent, despite the three obligatory so-called preventative measures. So far, literature data provide no compelling evidence that expectations have been met in this regard. A critical appraisal of volume preload, ephedrine prophylaxis and left lateral supine position shows that the preventative measures should be re-evaluated. New avenues should be explored aiming at a better prevention and decrease in both the prevalence and magnitude of post-spinal hypotension at cesarean section.
