Influence of Nociception Level Monitor (NOL) During Guided Analgesic Delivery in Breast Surgeries on the Perioperative Course, Quality of Recovery and Hospital Stay
In Brief
A clinical study evaluating NOL monitor for Anesthesia; Adverse Effect and Breast Cancer. Completed, enrolled 60 participants across 1 site.
Detailed Summary
To assess if perioperative consumption of opioids can be optimized with the assistance of a Nociception Level (NOL) monitor in breast surgery patients receiving pectoral and parasternal nerve blocks as supplementation to general anaesthesia. Hypothesis: 1. NOL monitor guidance optimizes perioperative analgesic consumption and postoperative length of stay and offers a better quality of recovery in breast surgery. 2. Intraoperative NOL monitoring can detect the efficacy of pectoralis and parasternal nerve blocks. 3. Incidence of persistent neuropathic pain after breast cancer surgery is lower in patients receiving lower doses of perioperative opioids.

Timeline
Interventions
NOL technology uses a multiparameter-based sensor platform, and advanced algorithm, to continuous monitor Autonomic Nervous System (ANS) functions. NOL reflects a patient's nociceptive state and analgesic effect, helping to optimize the administration of systemic and/or regional analgesics and avoiding overdose or underuse of these drugs. The nociception level is a multiparameter monitor that combines information from the finger photoplethysmogram amplitude, skin conductance, skin conductance fluctuation, heart rate, heart rate variability, and their time derivatives into one index ranging from 0 (absence of noxious stimulation) to 100 (severe noxious stimulation). The nociception level is a composite score derived from a set of physiologic variables (i.e., peripheral effectors of the autonomous nervous system): heart rate, heart rate variability, the amplitude of the photoplethysmogram, skin conductance, skin conductance variability, and the time derivatives of these variables.
