Design outcomes

Primary

MeasureTime frame
To observe the preoperative values of IVCCI, dIVCmax/IVCCI ratio and IVC: Ao index in patients undergoing surgery under spinal anesthesia. To evaluate the predictive values of IVCCI, dIVCmax/IVCCI ratio and IVC: Ao index for detecting PSAH.Timepoint: One hour post induction—

Secondary

MeasureTime frame
To find the incidence of PSAH To compare the predictive values of IVCCI, dIVCmax/IVCCI ratio and IVC: Ao index to detect Post Spinal Anesthesia Hypotension â?¢ To find any other clinical or perioperative variable which may predict PSAHTimepoint: One hour post induction—
