Recent metaanalysis showed significantly reduced hypotension and bradycardia in patients undergoing caesarean section in spinal anesthesia when 5-hydroxytryptamine 3 receptor antagonists were used prophylactically.~Due to this fact in our clinic the standard procedure was changed. All patients for caesarean section receive Granisetron before spinal anesthesia.~The aim of the present study is to evaluate the usage and dose of sympathomimetics during spinal anesthesia.~Therefore the investigators will evaluate approximately 120 participants who received granisetron and 120 participants who did not receive 5-hydroxytryptamine 3 receptor antagonists.
The aim of the present study is to quantify the dose and usage of sympathomimetics used in caesarean section.
