Clinical Trial Summary

compare the time of second hypotension after administration of three different doses of ephedrine 5,10,15 mg

Description:

In cesarean section, under subarachnoid block the most common complication is hypotension with a reported incidence greater than 80%. Hypotension may occur even after left uterine displacement and preloading with crystalloid. The severity of hypotension depends on the degree of aortocaval compression syndrome, the amount of crystalloid preloading, doses of local anesthetic drugs administered. The most effective treatment of hypotension associated with cesarean section under subarachnoid block is the administration of vasopressor drugs.
