In my opinion, the inclusion of PTA in the monitoring protocol allows us to complete the information and refine the treatment in something as complicated as nociception, thinking not only intraoperatively but also in postoperative pain

Currently, the clinical assessment method for nociception (intraoperative ‘pain’) is based on simple but basic responses, such as sudden increases in heart and respiratory rates or blood pressure. These responses imply that we are late in providing a good pain reliever and stability plan for our patients. The PTA monitor is a novel approach and a significant advance to detect the presence of nociception, and to anticipate situations where our patients do not have sufficient analgesic coverage.

The evaluation of the autonomic nervous system during general anesthesia allows for more accurate control of what happens after nociceptive stimuli. The PTA monitor allows me to detect most of the sympathetic responses that occur during surgery, even the ones that are very slight and do not cause major changes in blood pressure and heart rate.
