Design of Non-invasive Multi-parameter Pain Monitoring System

Abstract

Postoperative pain management of patients is a major medical and nursing challenge. Pain is still being measured in hospitals using Pain scales such as Faces scale. However this type of interpretation is not straightforward and management of postoperative pain using these methods continues to remain problematic and unsatisfactory. Poorly managed pain may interfere with postoperative complications, cause patient suffering and prolong recovery. In this paper, a multi-parametric method of objective pain monitoring using ECG, pulse rate and heart rate is proposed. The case of post-caesarean pain is taken up and the study showed that sympathetic tone increased, vagal tone decreased, heart rate and pulse rate increased during pain. A statistical‘t’ test was performed on the data obtained from patients and the test results justified the conclusion.
