Comparison of Mephentermine and Norepinephrine infusions for prevention of post-spinal hypotension during elective caesarean delivery:a randomised,double-blind trial.

Spinal anesthesia is the preferred technique for elective caesarean section  due to rapid onset , ease of administration, and minimal foetal drug exposure. however,  one of the most frequent and clinically significant  complication is post spinal hypotension, resulting from sympathetic blockade leading to vasodilation and reduced venous return.in pregnant  patients it can lead to both maternal  and foetal complications  therefore  its crucial to ensure hemodynamic stability .this thesis emphasis on current strategies to overcome post spinal hypotension  with maximal efficacy.
