Summary

Laparoscopic surgeries are now more popular because of the advantages such as shorter hospital stay, minimal scar. In order to perform laparoscopic surgery, pneumoperitoneum should be initiated. The optic nerve sheath is an extension of the dura mater and the subarachnoid space is continuous with the intracranial subarachnoid space. Therefore, non-invasive monitoring of the increase in intracranial pressure (ICP) can be achieved by measuring the optic nerve and sheath diameter with ultrasound. Since ONSD measurement with ultrasound is an easily applicable technique, it is useful in monitoring intracranial pressure changes based on the optic nerve diameter during intraoperative changes

Conditions

  • Cholecystitis

Interventions

OTHER

insufflation

Laparoscopic surgery begins with intraabdominal placement of the insufflation needle or trochar, followed by carbon dioxide (CO2) insufflation of the abdominal cavity to an intraabdominal pressure (IAP) of 12 to 15 mm Hg (Normal values are 5-7 mmHg) it is aimed to monitor optic sheat nerve diameter and lung ultrasound score changes with different intraabdominal pressures.

OTHER

desufflation

Laparoscopic surgery begins with intraabdominal placement of the insufflation needle or trochar, followed by carbon dioxide (CO2) insufflation of the abdominal cavity to an intraabdominal pressure (IAP) of 12 to 15 mm Hg. When the surgery is completed, the trochars are removed and intra-abdominal pressure is returned to normal which is 5-7 mmHg.
