Exploration of Autonomic Nervous System by Photoplethysmography

ASST Fatebenefratelli Sacco·observational·Posted Dec 24, 2014·Updated Jun 25, 2015

In Brief

An observational study evaluating autonomic nervous system analysis for Intervention Affecting Autonomic Nervous System. Completed, enrolled 52 participants across 1 site.

Detailed Summary

The autonomic nervous system state (ANSS) and the autonomic nervous system state index (ANSSi) - two indices derived from the pulse photo-plethysmography analysis - have been recently advocated as a measure of sympathetic activity in the anesthetized patients, but their validity has not been yet demonstrated. We will conduct a study aiming to assess if ANSS and ANSSi reflect autonomic nervous system modulation on cardiovascular system in healthy humans under general anaesthesia.

Interventions

autonomic nervous system analysisprocedure

electrocardiographic and pulse-photoplethysmographic waves of patients under general anesthesia for laparoscopic cholecystectomy will be recorded on a laptop pc for offline analysis of autonomic nervous system modulation a three main time point: 1) at baseline, before general anesthesia induction, 2) five min after tracheal tube placement, 3) five min after pneumoperitoneum insufflation.
