The complexity analysis of cerebral oxygen saturation during pneumoperitoneum and Trendelenburg position: a retrospective cohort study.

ABSTRACT:

Background

The human brain is a highly complex and nonlinear system, nonlinear complexity measures such as approximate entropy (ApEn) and sample entropy (SampEn) can better reveal characteristics of brain dynamics. However, no studies report complexity of perioperative physiological signals to reveal how brain complexity associates with age, varies along with the development of surgery and postoperative neurological complications.

Aim

This study examined the complexity of intraoperative regional cerebral oxygen saturation (rSO₂), aiming to reveal brain dynamics during surgery.

Methods

This retrospective cohort study enrolled patients who scheduled for robot-assisted urological surgery. Intraoperative rSO₂ was continuously monitored throughout the
