Comparison of Maternal Hemodynamics During Spinal Anesthesia with Different Cesarean Delivery Positioning

"1. Group A (N=72): Immediate Supine Position (Control):~ Immediately after administering spinal anesthesia, participants will be placed in a supine position. To reduce the risk of aortocaval compression, a slight left lateral tilt (approximately 15 degrees) will be applied. This is the traditional positioning method and serves as the control group for comparison.~2. Group В (N=72): Sitting Position:~ After spinal anesthesia, participants will be positioned in a sitting position with the ack supported at a 90-degree angle for the first 2 minutes. Knees will be bent, and feet will be supported.~3. Group С (N=72): Semi-Sitting Position:~After spinal anesthesia, participants will be positioned in a semi-sitting position with the back supported at the back supported at for the first 2 minutes.~Similar to the sitting position, knees and feet will be flat."
