Methods: After institutional ethics committee approval, prospectively collected data of 1824 parturients undergoing C/S at Van Training and Research Hospital between August 2014 and February 2015 were reviewed. Parturients with high preoperative anxiety scores (visual analogue scale for anxiety (VAS-A)≥70) undergoing C/S under spinal anesthesia with thiopental (Group S=49) and without any other type of sedation (Group NS=53) were included in the analysis. All parturients received SA with hyperbaric bupivacaine 0.5% 2.5 mL. Hemodynamic parameters were documented and maximum systolic arterial pressure (SAP) reductions from the baseline after spinal anesthesia were calculated. Incidences of hypotension (SAP≥30% decrease from baseline or <100 mmHg) and bradycardia (HR<55 beats/min), and related-ephedrine and -atropine requirements were noted. All data were obtained from the surgical database and patient charts. Primary endpoint of our study was to compare the maximum SAP reductions from the baseline values in Groups S and NS. Secondary endpoints were incidences of hypotension and bradycardia, required ephedrine and atropine doses, newborn Apgar scores at 1st and 5th min.
