Summary

The Lloyd Davies position is a position used in laparoscopic hysterectomies where the head is lowered 45 degrees and the legs are bent from the knee area.It is a version of the Trendelenburg position. Both this position and for laparoscopic surgery carbon dioxide (CO2) gas given into the abdomen, causes problems for the patient. Increased abdominal and thoracic pressure impairs venous return and increases intracranial pressure. Optic nerve sheath diameter can be measured by placing an ultrasound probe over the eye. It is possible to follow up the increase in intracranial pressure with this diameter measurement. In this study, it was planned to measure the optic nerve sheath diameter by ultrasound in patients who will undergo laparoscopic hysterectomy. It is aimed to observe the changes in the increase in intracranial pressure as the time lengthens with the measurements to be made at certain intervals during the operation. Secondary aim is to determine whether there is a cut-off value where the intracranial pressure starts to increase.

Conditions

  • Intracranial Pressure Increase

Interventions

DEVICE

ultrasound guided optic nerve sheath diameter measurement

First, both eyes were measured in a neutral position while awake and after intubation. Measurements were made at regular intervals until the end of the operation after the head-down position and in the neutral position after the operation.
