Certain risk factors play a role in altering the incidence of hypotension. Aortocaval compression counteraction does not help to prevent hypotension. Intravenous crystalloid prehydration has poor efficacy; thus, the focus has changed toward co-hydration and use of colloids. Phenylephrine is established as a first- line vasopressor, although there are limited data from high-risk patients. Ephedrine crosses the placenta more than phenylephrine and cause possible alterations in the foetal physiology. Key Words caesarean section, hypotension, spinal anaesthesiaen-USArticle
