Breathing support and brain pressure during keyhole surgery
Part of Brain & nervous system clinical trials.
This study looks at how different ways of breathing support during laparoscopic (keyhole) surgery affect pressure inside the head and blood flow to the brain, depending on the tilted position you're in. It aims to find the safest breathing method for your brain during surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You can be any age.
- You must be in generally good health (classified as ASA I, II, or III by the anesthesiology team).
- Your surgery must be done in one of two tilted positions: head-down (Trendelenburg) or head-up (Reverse Trendelenburg).
- You must be on a breathing machine (mechanical ventilation) during the surgery.
- You cannot have serious heart or lung disease, brain conditions, or be on blood thinners that cannot be stopped.
- You must be able to understand and follow study instructions.
