  Purpose
The hypothesis of the study is: Does the Surgical Stress Index (SSI) correlate with the Behavioral Pain Scale (BPS), the Ramsay Sedation Scale (RSS)and/or the Behavioral Pain Scale(BPV) and can therefore be used to monitor the quality of analgosedation in noncommunicative intensive care unit patients?

Condition
Analgesia Sedation Mechanical Ventilation Pain Stress Intensive Care Unit Critical Care

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Cross-Sectional
Official Title: SSI for Monitoring of Analgesia and Sedation in Critically Ill Patients

Estimated Enrollment: 60
Study Start Date: August 2008
Study Completion Date: October 2009
Primary Completion Date: August 2009 (Final data collection date for primary outcome measure)
Groups/Cohorts
Expected ICU
Patients with expected postoperative admission to the ICU. Baseline measurement of SSI. Exploration prior to weaning.
Unexpected ICU
Patients with unexpected stay at the ICU. No baseline measurement of SSI. Exploration in `steady state` of analgosedation.

Detailed Description:
The Surgical Stress index (SSI) was developed as a bedside tool to measure `pain` during surgery. First trials showed a good correlation between SSI and aching procedures and a negative correlation to the dosage of Remifentanil. The first evaluation studies were performed under Propofol and Remifentanil anaesthesia. A different site of use for the Surgical Stress Index could be the intensive care medicine. `Analgesia and Sedation are essential elements of intensive care treatment and relevant for patient outcome... There is therefore a need to monitor and define the level of sedation and pain and to provide the critically ill patient with adequate analgesia and sedation.` (j. martin 2002). Although the Ramsey Sedation Scale was never proven for validity and reliability it is an often used score for measurement of sedation quality. (Ramsay 74, Hansen-Flaschen 94, Jacobi 02, Martin 04). The Behavioral Pain Scale showed , apart from systolic blood pressure and heart rate, to be reliable and valid for measuring pain in noncommunicative, mechanical ventilated intensive care unit patients. (Payen 01, Jacobi 02, Aissaoui 05) These scales need to be performed a few times a day to be up to date and therefore time consuming for the intensive care staff. The Surgical Stress Index could be a non-invasive, bedside and online tool for measurement of sedation and/or analgesia in this complex patient group.
