Design outcomes

Primary

MeasureTime frame
To derive and study changes in internal carotid artery blood flow ultrasonographically in patients undergoing elective laparoscopic cholecystectomy under general anaesthesia in terms of internal carotid artery diameter, internal carotid artery velocity and beat volumeTimepoint: 1- Awake - just before induction of anaesthesia. 2- Two minutes after induction of anaesthesia, 3- Two minutes after creation of pneumoperitoneum and 4- Two minutes after providing head up tilt.—

Secondary

MeasureTime frame
To derive and calculate cardiac output by Liljestrand and Zander formulaTimepoint: 1- Awake - just before induction of anaesthesia. 2- Two minutes after induction of anaesthesia, 3- Two minutes after creation of pneumoperitoneum and 4- Two minutes after providing head up tilt.—
