No results posted yet for this study

Summary

The aim of this observational study was to understand the effect of ReverseTrendelenburg position, Trendelenburg position on intracranial pressure and carotid blood flow in patients undergoing laparoscopic surgery. The main question it aims to answer is:

Does ReverseTrendelenburg position increase common carotid artery (CCA) flow, optic nerve sheath diameter (ONSD); does Trendelenburg position decrease CCA flow, ONSD.

Conditions

  • Laparoscopic Surgery

Interventions

DEVICE

operating position

In the Trendelenburg position, the operating table was tilted head down at an angle of 20-25°. In the Reverse Trendelenburg position, the operating table was tilted head up at an angle of 20-25°.

DEVICE

pneumoperitoneum

Pneumoperitoneum was established with an intra-abdominal pressure of 10-15 mmHg.
