New Study: Postoperative Pain Can Be Reduced by Using NOL Monitoring to Guide Analgesic Medication During Surgery
RAMAT GAN, Israel, Sept. 29, 2020 /PRNewswire-AsiaNet/ --

A new study has found that monitoring pain response levels during surgery with 
NOL technology (Medasense, Ramat Gan, Israel) can help reduce postoperative 
pain. Exploring the potential use of NOL monitoring to help enhance recovery 
after surgery, the study demonstrated that patient pain scores after surgery 
were 33% lower when administration of pain medication during surgery was guided 
with NOL monitoring. 

"High pain scores following surgical procedures are common and are associated 
with poor patient outcomes; but on the other hand we know that excessive use of 
opioids administered during the surgery itself to prevent postoperative pain 
can cause other complications," explains Prof. Dahan of Leiden University 
Medical Center's Department of Anesthesiology, who led the study.

NOL monitoring provides a reliable index to objectively detect and quantify 
noxious stimuli during anaesthesia, when patients can't communicate, guiding 
the clinical team in tailored opioid dosing for each patient. Earlier studies 
have shown that the NOL index outperforms other indexes for monitoring of pain 
response to surgical stimuli and that NOL-guided analgesia resulted in reduced 
intraoperative opioid consumption, leading to fewer intraoperative hypotensive 
events.

The new study, just published in the British Journal of Anaesthesia (BJA)[1] 
[https://bjanaesthesia.org/article/S0007-0912(20)30681-4/fulltext] followed 50 
patients undergoing elective abdominal surgery in a two-center randomized 
controlled trial. The patients were randomly divided so that one group received 
NOL-guided analgesia dosing during the surgery and the control group received 
analgesics according to standard of care (based on hemodynamic monitoring). The 
study showed that while there was no increase in overall dosing in the 
NOL-guided group, the patients in that group reported less pain in the first 90 
minutes compared to the control arm. 

In addition, stress hormone levels (ACTH and cortisol) were on average up to 
50% lower in the NOL-guided group, which clinically aligns with the lower pain 
response levels in those patients during surgery. 

"Clinicians using NOL monitoring to guide analgesia are able to identify more 
accurately when a patient's pain response level rises and to tailor analgesic 
medication more accurately. As we found that opioid dosing overall was not 
different between the groups, we can confidently relate the difference in 
outcomes to the timing of individualized dosing as guided by the NOL monitor," 
Prof. Dahan concluded.

About Medasense and NOL Technology

Medasense (www.medasense.com) offers a breakthrough technology that enables 
clinicians to optimize and personalize pain control and avoid overmedication. 
Medasense's flagship product, the PMD-200™ with its NOL® index, is a unique 
platform that objectively monitors and quantifies the patient's pain response 
by means of artificial intelligence and a proprietary non-invasive sensor 
platform.  

The PMD-200 is used to optimize pain management in critical care and operating 
rooms settings, where patients are unable to communicate.

Clinical studies have demonstrated its impact on patient safety and outcomes, 
including opioid sparing.

The PMD-200 is distributed in Europe exclusively by Medtronic, is cleared for 
marketing also in Canada, Latin America, Israel and Australia, and enables 
connectivity with Philips patient monitors.
