Comparison Of The Effects Of Two Different Low-Doses Of Isobaric Bupivacaine On Intraoperative Hemodynamics In Spinal Anesthesia During Cesarean Section: A Randomized Controlled Trial

The primary aim of this study was to compare the effects of two different low-dose bupivacaine used in spinal anesthesia on intraoperative hemodynamics in cesarean section operations.Investigators think that low-dose bupivacaine and fentanyl mixture applied in cesarean section cause fewer hemodynamic changes,provide adequate anesthesia and analgesia quality,cause fewer side effects,and postoperatively,patients may return to their daily activities more quickly.This study was conducted on 80 pregnant women undergo an elective cesarean section.Patients were randomly allocated in GrupA and GroupB. Combined spinal-epidural anesthesia was performed in the sitting position using the needle-inside-needle technique.After cerebrospinal fluid flow was observed, GroupA patients were given a solution containing 5 mg isobaric bupivacaine+15 µg fentanyl (1.3 ml),and Group B was administered a solution containing 7 mg isobaric bupivacaine+15 µg fentanyl (1.7ml).Hypotension,bradycardia,duration of analgesia,postoperative nausea and vomiting were recorded.
