Pain Clinical Trial - Clinical Evaluation of Medasense Pain Monitor

Status Completed

Clinical Trial Summary

In this study, the performances of Medasense's non-invasive pain monitoring is compared with standard pain related indicators, such as heart rate, galvanic skin response, etc. , and with a subjective pain level assessment. The subjective pain level is assessed by the anesthesiologist when the patient is under general anesthesia and by the patient and a nurse in post anesthetic care unit (PACU).

The study is based on recording and analyzing the subject's physiological signals, while recording painful events, medication dosing and different clinical signs.

Clinical Trial Description

Pain is an unpleasant sensation, ranging from slight discomfort to intense suffering. Since pain is a subjective phenomenon, it has frequently defied objective, quantitative measurements. Today, in order to measure pain, subjective uni-dimensional scales are used to quantify pain. One of the most common scale used to rate a patient's pain intensity is the visual analog scale (VAS), usually scored from 0 to 100. Hitherto, those scales are based on the subjective evaluation of pain by the patient.

During anesthesia the patient cannot communicate and therefore the verbal or other report is impossible. Therefore, due to misrepresentation of the existence or extent of pain, care providers may fail to estimate the correct measure of pain and give too much or too little medication. A scoring system of pain level is therefore needed. That is the problem Medasense's system tries to approach.

In this study investigators intend to test and analyze the performances of Medasense pain monitor by comparing its results with standard pain related indicators and with subjective patient's pain level assessment. The patient's pain level will be assessed by the anesthesiologist during surgery based on known pain stimuli, medications administered and clinical signs, and by the PACU nurse and patient's reports, when the patient is in recovery. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
