During cesarean section operations, anxiety is quite high. This anxiety also affects the choice of the form of anesthesia. Providing patients with detailed information during preoperative period reduces this anxiety. In the present study, we aimed to investigate the effect of demonstrating a video of administering spinal anesthesia technique to pregnant women on their anesthetic method preferences. After the approval of the ethics committee, the techniques that can be applied during the preoperative evaluation were verbally explained to the pregnant women and the prepared questionnaires were asked. Then, those who were willing to watch an informative video about spinal anesthesia were demonstrated the video. A total number of 412 patients were included in the study. After being verbally informed, 163 (39.6%) of the pregnant women preferred general anesthesia, 166 (40.3%) preferred regional-anesthesia, while 83 (20.1%) of them were hesitant. 98 (23.8%) of the pregnant women stated that they did not have information about anesthesia techniques that can be applied, while 314 (76.2%) of them stated that they were informed. 352 pregnant women (85.4%) watched the video. After video demonstration, those who preferred spinal anesthesia accounted for 62.4%, while others who preferred general anesthesia accounted for 37.6%. 63.9% of the patients watching the video reported that the video demonstrated to inform them was influential in their preferences of anesthesia technique. In conclusion, demonstrating informative video concerning the choice of anesthesia for cesarean section is effective in choosing a method of anesthesia.
