The objective of this study is to evaluate a new medical device in the management of pain. The principle of this new treatment is based on the emission of electromagnetic radiation in millimeter band. This new modality of pain management is evaluated in a perioperative management in patients undergoing surgery for aortic valve replacement.
The hypothesis is that the use of this medical device in perioperative would reduce the consumption of postoperative morphine with an identical quality of analgesia. The decline in morphine consumption would allow a decrease in opioid adverse effects.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| conventional management of postoperative pain | No Intervention | Patients who have had an aortic valve replacement surgery have a conventional management of pain after surgery. The pain is treated by morphine using a patient-controlled analgesia for the administration. Patients are recruiting prospectively or possibly retrospectively. The management is usual, nothing from the conventional care of patients change, only data will be collected. | |
| Medical device - electronic-pain killer | Experimental | In addition to the conventional management of postoperative pain, patients benefit from perioperative treatment sessions with medical device. Patients are recruiting prospectively. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Medical device - electronic-pain killer | Device | Treatment sessions with the medical device (no-marked EC): 2 sessions before surgery and 4 or 5 sessions until 48 hours after surgery. Each treatment sessions takes 45 minutes. Each session is spaced by 12 +/-3 hours. |
| Measure | Description | Time Frame |
|---|---|---|
| Cumulative consumption of morphine auto-administered in the experimental group in the first 48 hours : descriptive analysis | The morphine cumulative consumption administered by auto-analgesia in the experimental group at 24 and 48 hours after the surgery | 48 hours |
| Measure | Description | Time Frame |
|---|---|---|
| Cumulative consumption of morphine auto-administered in the control group in the first 48 hours : descriptive analysis | The morphine cumulative consumption administered by auto-analgesia in the control group at 24 and 48 hours after the surgery | 48 hours |
| Determine the number of patients required to demonstrate a 30% decrease in morphine consumption within the first 48h following aortic valve replacement surgery in a population treated with "Electronic-Pain-Killer" compared to conventional pain management |

Cumulative morphine consumption in milligrams, administered by auto-analgesia, at 48 hours post-operatively in the experimental and control groups. |
| 48 hours |
| Troponin's peak characterization in the first 48 hours postoperatively. | The troponin is assessed in ng/ml in the two groups from the end of the surgery until 48 hours postoperatively | 48 hours |
| The Pain characterization: Echelle Numérique Standard; standard digital scale | The patient pain is evaluated using the ENS (Echelle Numérique Standard; standard digital scale, score between 0 to 10) for both groups. | 48 hours |
| The hospitalization length in the intensive care unit | For the two groups, the hospitalization length in the intensive care unit is assessed in hours. | 48 hours |
| Characterization of analgesic drugs | The analgesic drugs are characterized by their class, dose and number of dose taken in the two groups since they are in the intensive care unit. | 48 hours |
| Number of postoperative nausea or vomiting events (number of PONV) in the experimental group | In the experimental group, the number of PONV events requiring a treatment is assessed. | 48 hours |
| Delirium events in the experimental group | The number of delirium events is assessed using the CAM-ICU (Confusion Assessment Method for the Intensive Care Unit) scale in the experimental group. | 48 hours |
| Adverse effect from the medical device | The number of adverse effects from the medical device is assessed from the first session with the medical device to the follow-up visit. | 48 hours |
| Description of the medical device use | Log files of the medical device are extracted. The length of each session, the start and end session times, each stopping is analysed. | 48 hours |
| Medical device acceptability : score | This score has been specifically created for the electronic pain killer medical device. Each item range from 0 (the worst) to 10 (the best). | 48 hours |
| Medical device acceptability : descriptive analysis | Open questions will be asked in a questionnaire without scale. A descriptive analysis will be done with the answers. | 48 hours |
| Use Error evaluation : System Usability Scale (SUS) | The System Usability Scale (SUS) contains 10 questions that are rated on a scale from 1 to 5. "The participant's scores for each question are converted to a new number, added together and then multiplied by 2.5 to convert the original scores of 0-40 to 0-100." Jeff Sauro established the average score of SUS is 68. The score can go from 0 (worst) to 100 (best). | 48 hours |
| Subgroup analysis excluding patients who have had Nefopam administration | To avoid a potential bias confusion, patients taking Nefopam drug are excluded from the analyses and all the previous outcome are assessed again. | 48 hours |
