Monitoring Nociception Using NoL Index to Reduce Opioid-Related Complications in Laparoscopic Abdominal Surgery

The NoL Monitor (PMD-200) is a multi-parameter sensor device placed on the patient's finger to estimate nociception levels during surgery. It provides continuous, real-time feedback to the anesthesiologist on the patient's nociception, assisting in the optimization of analgesic drug administration. The monitor integrates parameters such as heart rate variability, skin conductance, and other physiological signals to compute the NoL index, which ranges from 0 to 100, with target values between 10 and 25 for optimal nociception management.
