Photoplethysmography and nociception
Acta Anaesthesiologica Scandinavica, 2009Photoplethysmography (PPG), i.e. pulse oximetric wave, is a non‐invasive technique that is used in anaesthesia monitoring primarily to monitor blood oxygenation. The PPG waveform resembles that of the arterial blood pressure but instead of pressure it is related to the volume changes in the measurement site and hence contains information related to the

In recent years, progress in the treatment of pain has been strongly influenced by new insights into the mechanisms underlying pain and nociception. The following article briefly reviews some recent reports which make a significant contribution to our knowledge of the structure and function of nocisensors, the neuropeptides involved in the nociceptive ...

AbstractThe biomimetic characteristics of the memristor as an electronic synapse and neuron have inspired the advent of new information technology in the neuromorphic computing. The application of the memristors can be extended to the artificial nerves on condition of the presence of electronic receptors which can transfer the external stimuli to the ...

Depth of Anesthesia and Nociception Monitoring: Current State and Vision For 2050.
Anesthesia and AnalgesiaAnesthesia objectives have evolved into combining hypnosis, amnesia, analgesia, paralysis, and suppression of the sympathetic autonomic nervous system. Technological improvements have led to new monitoring strategies, aimed at translating a qualitative ...

Publisher Summary This chapter describes the algesic peptides, opioid peptides, naloxone-sensitive nonopioid peptides, naloxone-insensitive peptides, and peptides with mixed effects. The chapter presents certain criteria that need to be fulfilled to demonstrate the involvement of an endogenous peptide in nociception.

Intraoperative Nociception Monitoring
Anesthesiology Clinics, 2021Nociception refers to the process of encoding and processing noxious stimuli. Its monitoring can have potential benefits. Under anesthesia, nociceptive signals are continuously generated to cause involuntary effects on the autonomic nervous system, reflex movement, and stress response. Most available systems depend on the identification and measurement

INTRODUCTION Under-dosage or over-dosage of intraoperative analgesia can cause harm to patients. Many studies have demonstrated the clinical advantages of nociception monitoring tools, but with some conflicting results.

The potential importance for nociception of P2X receptors, the ionotropic receptors activated by ATP, is underscored by the variety of pain states in which this endogenous ligand can be released. Several important findings have been made recently indicating that P2X receptors can be involved in pain mechanisms both centrally and in the periphery.

BACKGROUND The NOL index is based on multiparametric analysis of heart rate (HR), skin conductance, wave plethysmography, and their time derivative. The aim of this study was to evaluate the NOL to detect standardized nociceptive stimuli with various ...

There is evidence that the cerebral cortex is involved in the perception of pain but no specific area appears to be the ‘pain centre’. Limited knowledge exists on the cortical processing of the noxious input. The nociceptors are most likely to activate at least two different systems with different characteristics.
