Total Hip Arthroplasty (THA)NCT07747142
Comparison Between Opioid-sparing Anesthesia Guided by the CARDEAN® Index and Opioid-free Anesthesia During Total Hip Arthroplasty
A study testing Titrated Opioid Sparing Anesthesia and opioid free anesthesia in people with Total Hip Arthroplasty (THA), run by Pole Sante Oreliance, Polyclinique des Longues Allees at 1 site in France.
Trial summary
The proposed study compares two anesthesia techniques; the hypothesis being tested is that titrating sufentanil based on the CARDEAN® index (titrated OSA) does not increase post-operative morphine consumption compared to opioid-free anesthesia (OFA). Read more about this study

About this study
Official title: Comparaison Entre anesthésie Avec épargne Morphinique guidée Par l'Index CARDEAN® et anesthésie Sans Morphinique au Cours Des Arthroplasties Totales de Hanche : étude randomisée
The proposed study compares two anesthesia techniques; the hypothesis being tested is that titrating sufentanil based on the CARDEAN® index (titrated OSA) does not increase post-operative morphine consumption compared to opioid-free anesthesia (OFA). This CARDEAN®-guided titrated anesthesia approach could potentially allow for hospital discharge as early as 24 hours post-operatively and is compatible with ERAS protocols. The primary objective is to demonstrate that sufentanil administration guided by the CARDEAN® index (titrated OSA) does not increase postoperative morphine consumption compared to opioid-free anesthesia (OFA). This is a prospective, single-center, randomized, single-blind, non-inferiority study.
Two groups of 70 patients each (140 patients in total) are compared based on the type of intraoperative analgesia: titrated OSA (Arm 1) versus OFA (Arm 2).
Randomization will be performed at a 1:1 ratio and stratified by surgical approach (anterior or lateral approach).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Titrated Opioid Sparing AnesthesiaProcedure or surgery
Opioid-sparing anesthesia using the CARDEAN® index, which enables specific monitoring of nociception during general anesthesia.
By adjusting sufentanil administration in real time based on variations in surgical painful stimuli, the CARDEAN® index enables titrated opioid-sparing anesthesia (titrated OSA).
opioid free anesthesiaProcedure or surgery
anesthesia performed without opioid administration
| Study group | Role | What they receive |
|---|---|---|
| Titrated Opioid Sparing Anesthesia | Experimental | Not described Receives: Procedure: Titrated Opioid Sparing Anesthesia |
| Opioid Free Anesthesia | Active comparator | Not described Receives: Procedure: opioid free anesthesia |
What is being measured
The primary outcome is the main question the study is designed to answer.
Total dose of morphine required to maintain a pain score ≤ 3 on a numerical scale of 1 to 10 during the first 24 hours (dose expressed as oral morphine equivalent, OME)
Measured: During the first 24 hours after the start of anesthesia
Secondary outcomes (13)
Stability of heart rate (HR) and mean arterial pressure (MAP)
- Number of heart rate episodes deviating by ±20% for more than 15 seconds from the baseline heart rate, relative to the duration of the procedure
- Number of mean arterial pressure (MAP) values deviating by ±20% from the baseline MAP, relative to the duration of the procedure
- Number of boluses and total doses of cardiotropic and vasoactive drugs: atropine, norepinephrine, nicardipine

Measured: Time interval between the end of the procedure and extubation

Adverse effects of postoperative opioids
Number of hypoxia episodes in the PACU (hypoxia defined as SpO2 ≤ 94% on room air)
Measured: During the awakening
Discharge from the hospital is possible as early as 24 hours post-procedure for patients deemed eligible for early discharge (determined by the surgeon prior to the intervention).
Measured: Until 24 hours after surgery
Patient satisfaction: satisfaction questionnaire (completed on the day of discharge) regarding the management of any pain.
Measured: At discharge (between 24 and 48 hours after surgery)
Maximum pain score on a 0-10 numerical rating scale (NRS max) at rest and during movement
Measured: On postoperative days 1 and 2
IV morphine dose received in the PACU, expressed in MME
Measured: during the awakening
Morphine dose received in the surgical ward, expressed in MME, at 6, 12, 18, 24, 36, and 48 hours post-surgery (H0 = start of surgery)
Measured: Every 6 hours until 48 hours after surgery
Number of patients not receiving morphine in the PACU
Measured: during the awakening, 24 hours after surgery, 48 hours after surgery
Presence of postoperative nausea and/or vomiting (PONV)
Measured: Until up to 48 hours after surgery

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The proposed study compares two anesthesia techniques; the hypothesis being tested is that titrating sufentanil based on the CARDEAN® index (titrated OSA) does not increase post-operative morphine consumption compared to opioid-free anesthesia (OFA). This CARDEAN®-guided titrated anesthesia approach could potentially allow for hospital discharge as early as 24 hours post-operatively and is compatible with ERAS protocols. The primary objective is to demonstrate that sufentanil administration guided by the CARDEAN® index (titrated OSA) does not increase postoperative morphine consumption compared to opioid-free anesthesia (OFA). This is a prospective, single-center, randomized, single-blind, non-inferiority study.
Two groups of 70 patients each (140 patients in total) are compared based on the type of intraoperative analgesia: titrated OSA (Arm 1) versus OFA (Arm 2).
Randomization will be performed at a 1:1 ratio and stratified by surgical approach (anterior or lateral approach).
