Design outcomes

Primary

MeasureTime frame
To compare the accuracy of Corrected carotid flow time(FTc) and Inferior vena cava collapsibility index (IVC-CI) in predicting hypotension following spinal anaesthesia in elective caesarean section patientsTimepoint: Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), heart rate, respiratory rate, SpO2 will be noted every 3 minutes until delivery of the baby. The fall of MAP by 20 % from baseline or 65 mmHg will be considered as hypotension.—

Secondary

MeasureTime frame
To determine optimal cutoff values of FTc & IVCCI for predicting post spinal hypotension in parturientsTimepoint: Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), heart rate, respiratory rate, SpO2 will be noted every 3 minutes until delivery of the baby. The fall of MAP by 20 % from baseline or 65 mmHg will be considered as hypotension.—
