Aim: The position of pregnant may affect the incidence of maternal hypotension and characteristics of sensory block. The aim of this prospective study was to investigate the effects of two different sitting positions of pregnant women on the incidence and the onset of hypotension and on the onset of sensory block in pregnant women undergoing spinal anesthesia for elective cesarean delivery. Materials and Methods: A total of 93 patients were randomized into two groups: traditional sitting position (Group I; n = 47) and the group with legs extended parallel to the table (Group II; n = 46). The number of intrathecal applications, maximum level of sensory and motor block, time to sensory block at the level of T6, hemodynamic parameters, use of ephedrine and incidence of side effects were recorded at measurement time points. Results: The number of intrathecal applications, the time it took for the sensory block to reach the T6 dermatome level, the maximum sensory and motor block levels, the frequency of hypotension, the time it took for the first hypotension to develop, the amount of ephedrine used, and the arising complications did not significantly differ between the groups. Group I was shown to have a statistically significant longer transition time than Group II (p<0.05) from the sitting position to the supine position. Discussion: This study reveals that the sitting position of the pregnant woman has no relationship with maternal hypotension and block characters. Between the groups, the transition from the sitting position to the supine position was found to be shorter than the position in which the legs were extended parallel to the table.
