Does intramuscular ephedrine prevent systolic blood pressure changes better than intravenous ondansetron and Ringer's solution in patients undergoing cesarean section under spinal anesthesia?
Intramuscular ephedrine given 25 minutes before spinal anesthesia is more effective than intravenous ondansetron or Ringer's solution in preventing systolic blood pressure changes during cesarean section.
Intramuscular administration of ephedrine 25 minutes prior to the spinal anaesthesia leads to better prevention of systolic blood pressure changes compared with intravenous ondansetron and ringer, while administration of ondansetron and ringer had the same effects on reducing hemodynamic changes.
