At the end of your cesarean section surgery, which is started by applying medication to the spinal cavity from your waist, pain medication will be applied between the relevant muscle and its covering from your lower abdomen or back with the help of ultrasonography and a special block needle. Then, a patient-controlled pain device with a serum containing painkillers will be connected to your vascular access, and its use and purpose will be explained to you. You will be asked about your pain condition and the severity score of your pain, if any, at certain hourly intervals. At the end of 24 hours, a pain device will be removed, your satisfaction will be questioned and your complaints, if any, will be recorded. Immediately before surgery and 4-6 days after your surgery. An evaluation survey consisting of 10 questions will be asked to you within a 5-minute period during the weeks, at a time when you are free, and your answers will be recorded.
