Design outcomes

Primary

MeasureTime frame
To compare the subclavian vein and Inferior vena cava collapsibilty index in the prediction of postspinal hypotension in patients undergoing caesarean section under spinal anaesthesiaTimepoint: Pre spinal anaesthesia Heart rate, sysytolic blood pressure, diastolic blood pressure and mean arterial pressure is recorded. Postspinal anaesthesia vitals are recorded every 2 minutes interval for the first 20 minutes.—

Secondary

MeasureTime frame
To assess correlation between degree of hypotension and subclavian vein and inferior vena cava diameter and To estimate incidence of hypotension in patients undergoing caesarean section elective versus emergencyTimepoint: Pre spinal anaesthesia heart rate systolic blood pressure diastolic blood pressure and mean arterial blood pressure Post spinal anaesthesia vitals are recorded at every two minutes interval for the first twenty minutes—
