简要总结
Recently, a newly developed index, the Nociceptive Level (NOL) index, was validated and showed superiority over heart rate and blood pressure for recognition and grading of intense and mild nociceptive stimuli during surgery under general anesthesia.
We hypothesize that compared with standard management, NOL-guided anesthesia will lead to reduced postoperative pain scores, and during anesthesia, to increased hemodynamic stability.
详细描述
Uncontrolled postoperative pain may result in significant clinical, psychological, and socioeconomics consequences. Not only does inadequate pain management following surgery result in increased morbidity and mortality but it also may delay recovery, result in unanticipated readmissions, decrease patient satisfaction, and lead to chronic persistent postsurgical pain. Pain is multifactorial in nature and understanding both the complexity of pain and its side effects is imperative to achieve a successful surgical outcome.
Nociception/analgesia are currently assessed by monitoring changes in heart rate (HR), blood pressure (BP), and other indirect parameters which are not sensitive or specific to nociception. As a result, the patient may be given insufficient analgesia which can promote postoperative pain, or excessive analgesia which can result in overdosing and related complications.
