Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome is to measure the change in optic nerve sheath diameter on changing position from supine to trendelenburg position in elective laparoscopic surgeries as a surrogate marker for increased intracranial pressure.Timepoint: The patients will be observed firstly in supine position at 5 mins after induction of general anaesthesia and secondly, in trendelenburg position after achieving pneumoperitoneum and third, 5 mins after turning back to supine post-surgery after desufflation of pneumoperitoneum. | — |
Secondary
| Measure | Time frame |
|---|---|
| The impact of angle of trendelenburg position in surgery on optic nerve sheath diameter patients undergoing elective laparoscopic surgeries.Timepoint: The patients will be observed firstly, in supine position at 5 mins after induction of general anaesthesia & secondly, in trendelenburg position after achieving pneumoperitoneum & third, 5 mins after turning back to supine postsurgery after desufflation.;The impact of duration of trendelenburg position in surgery on optic nerve sheath diameter patients undergoing elective laparoscopic surgeries.Timepoint: The patients will be observed firstly, in supine position at 5 mins after induction of general anaesthesia & secondly, in trendelenburg position after achieving pneumoperitoneum & third, 5 mins after turning back to supine postsurgery after desufflation. | — |
