Exploration of Autonomic Nervous System by Photoplethysmography

NCT02324478 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 52

Last updated 2015-06-25

No results posted yet for this study

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.

Conditions

  • Intervention Affecting Autonomic Nervous System

Interventions

PROCEDURE

autonomic nervous system analysis

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.
