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

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

Cesarean delivery is a common surgical procedure, and maintaining maternal hemodynamic stability during the procedure is crucial for both maternal and fetal outcomes . Hemodynamic instability, such as hypotension following spinal anesthesia, is a frequent complication and can lead to adverse maternal and neonatal outcomes. Traditionally, after spinal anesthesia, women are positioned supine, sometimes with a slight left lateral tilt to mitigate the risk of aortocaval compression . However, recent studies and clinical observations suggest that delayed supine positioning-keeping the patient in a sitting or semi-sitting position for a period following spinal anesthesiamay improve hemodynamic stability. These alternative positions may help to mitigate the abrupt drop in blood pressure commonly seen after spinal anesthesia by allowing for a more gradual redistribution of blood volume . Understanding the optimal positioning strategy could lead to improved clinical protocols that enhance maternal and fetal safety. By comparing immediate supine positioning with delayed supine positioning (in sitting and semi-sitting positions), this study aims to provide evidence on which positioning strategy offers the best hemodynamic outcomes.
