Intraoperative Optic Nerve Sheath Diameter Changes After Laparoscopic Surgery

ClinConnect Summary

This clinical trial is studying how laparoscopic surgery, a less invasive type of surgery, affects the optic nerve sheath diameter (ONSD), which can give us clues about changes in pressure inside the skull, known as intracranial pressure (ICP). During laparoscopic surgery, carbon dioxide gas is used to create space in the abdomen, which may lead to increased ICP. Researchers are using ultrasound, a safe and painless imaging technique, to measure the ONSD and see if there are any changes during and after the surgery.

To participate in this trial, people aged 18 to 75 who are scheduled for laparoscopic surgery may be eligible. However, individuals with certain health conditions, such as severe heart or lung issues, or those with previous eye or neurological problems, will not be able to join. If you decide to participate, you can expect a straightforward process where your optic nerve sheath diameter will be measured before and after your surgery using ultrasound, helping researchers understand the effects of this surgical method on intracranial pressure.
