NCT04305015

Brief Summary

Previous work has shown that NOL (Medasense, Ramat Gan, Israel) accurately quantifies nociception during general anesthesia. Presumably, titrating opioids to NOL will therefore provide individual guidance so that patients will be given about the right amount. Patient given the right amount will presumably awaken quickly when anesthesia is done, and have good initial pain control in the post anesthesia care unit (PACU). To the extent that NOL titration facilitates optimal opioid dosing, patients are likely to have better PACU experiences - which would be an important outcome that clinicians and regulators are likely to take seriously.

Outcome Measures

Primary Outcomes (1)

  • PACU pain score

    Average pain scores (0-10 verbal response scale) at 10-minute intervals during the initial 60 minutes of recovery are more often between 1 and 3 or significantly lower with NOL-guided fentanyl than with routine care

    60 minutes during recovery

Study Arms (2)

Routine opioid management

ACTIVE COMPARATOR

Clinicians will be blinded to NOL monitoring and use clinical judgement to determine how much fentanyl should be given, and when

Other: Routine opioid management

NOL-guided opioid administration

EXPERIMENTAL

Clinicians will titrate fentanyl to keep NOL under 25 - always using good clinical judgement for individual patients

Device: NOL Guided Analgesia

Interventions

NOL values exceeding 25 will typically be treated with boluses of fentanyl 50 µg at roughly 5-minute intervals. The target will be maintained until surgery ends

Also known as: Physiological Monitoring Device: PMD-200 system
NOL-guided opioid administration

Clinical judgement will be according to their standard practice and may include interpretation of blood pressure, heart rate, diaphoresis, tearing, and pupil size. Boluses of fentanyl 50 µg can be given per clinical judgement

Routine opioid management

Eligibility Criteria

Age21 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults having major non-cardiac surgery expected to last ≥2 hours;
  • American Society of Anesthesiologists physical status 1-3;
  • Age 21-85 years old;
  • Planned endotracheal intubation

You may not qualify if:

  • Routine user of psychoactive drugs other than opioids;
  • Contraindication to sevoflurane, fentanyl, morphine, or ondansetron.
  • Intracranial surgery
  • BMI \> 40

Masking Details
Anesthesia clinicians cannot be blinded since they will need to titrate opioid administration to NOL. However, all postoperative care and evaluations will be fully blinded to randomization, thus preventing measurement bias
