- Primary Outcome Measures
Name Time Method OPTIC NERVE SHEATH DIAMETER:- Measured through ultrasound assistance in both eyes. Primary goal is to compare the impact of Low versus Standard pressure pneumoperitoneum on Intracranial pressure using ultrasound assisted Optic nerve sheath diameter in patients undergoing elective laparoscopic cholecystectomyTimepoint: Optic nerve sheath diameter will be measured at following time intervals:- <br/ ><br>1.Before Induction of Anaesthesia <br/ ><br>2.5 minutes after induction in supine position <br/ ><br>3.10 minutes post pneumoperitoneum <br/ ><br>4.10 minutes after 30-degree reverse Trendelenberg positioning <br/ ><br>5.At every 20 minutes interval intraoperatively <br/ ><br>6.After returning to supine position without pneumoperitoneum
- Secondary Outcome Measures
Name Time Method 1.Haemodynamic changes:- Comparison of vital signs (Heart rate, Mean Arterial pressure) between the two groups at low versus standard pressure pneumoperitoneum <br/ ><br>2.To observe Complications, if anyTimepoint: Heart rate, Mean arterial pressure will be monitored:- <br/ ><br>1.At the time of Induction <br/ ><br>2.At the time of CO2 insufflation <br/ ><br>3.While patient is kept in Reverse Trendelenberg position <br/ ><br>4.Intraoperatively <br/ ><br>5.In supine position after exsufflation of gas
