Trial Outcomes & Findings for Evaluation of the Surgical Pleth Index During Spinal and General Anesthesia (NCT NCT00789438)

NCT ID: NCT00789438

Last Updated: 2010-07-13

Results Overview

Surgical Pleth Index (SPI), derived from finger photoplethysmographic signal has a range from 0 showing the lowest stress level to 100 showing the maximum stress level. SPI was compared between the groups during six defined time points: baseline (BL)- day before surgery; induction (IND)-before induction of general anesthesia or before spinal punction respectively; intubation (INT) or spinal punction (SPA); skin incision (INC), surgical suture (SU) and 10 minutes after admission to the recovery room (PACU). Difference between the groups is calculated using ANOVA.
