Oocyte retrieval, Sedation
Brief summary
Oocyte retrieval procedure for in vitro fertilization is a source of anxiety for patients. Local anaesthesia or sedation are commonly used to manage many situations of anxiety, including the oocyte retrieval. However, this sedation should be as mild as possible in order to preserve oocytes. HappyMed Video Glasses are a recent medical device that allows the immersion of patients in films, cartoons or concerts. By distracting patients, this technology can reduce anxiety, discomfort and ultimately pain associated with care. This randomized monocentric trial compares audiovisual distraction versus usual care for the management of anxiety and pain related to oocyte retrieval. Hypothesis of this study is that the audiovisual distraction carried out with the HappyMed Video Glasses reduces the use of sedative drugs during oocyte retrieval while ensuring a better comfort and a faster walking ability.
Detailed description
Consent female patients between 18 and 43 years old scheduled for oocyte retrieval will be enrolled in this study and their anxiety level will be collected via a questionnaire. After randomization, patients will either benefit from audiovisual distraction using HappyMed Video Glasses, (medical device with CE marking), or from the usual management during procedure. The anaesthesiologist will check that no anxiolytic or sedative drug was given 12 hours before anaesthesia. The patients will be stratified according to whether or not a previous intervention was performed. Anaesthesia will be started and maintained with administration of sufentanil (0.1 μg/kg) and propofol (using the Dixon's up-and-down method). The aim is a patient who spontaneously ventilates and does not react to gynaecological stimulation. Prevention of postoperative pain and nausea/vomiting will be carried out at the initiation of the surgical procedure. The effect of these drugs is longer than the intervention duration and will not influence the protocol.
Interventions
DEVICEHappyMed Video Glasses
HappyMed allows the immersion of patients in films, cartoons or concerts.
DRUGPropofol
The dosage is modified according to the Dixon's up-and-down method (using 0.5 µg/ml as a step size). The first patient in each group will start at a dose 3 µg/ml propofol. If patient manifests discomfort then the next patient will receive an increment of 0.5 µg/ml propofol, if patient is comfortable, then the next patient received a decrement of 0.5 µg/ml propofol.
DRUGSufentanil
0.1 µg/kg

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Target concentration of propofol administered during oocyte retrieval procedure to maintain the patient comfortable | Intraoperative period : from the start of anaesthesia to the end of the intervention | An up and down method will define the CP 50 in each group. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Side effects due to audiovisual distraction | 4 hours | Onset of vertigo, nausea or headaches |
| Patient comfort during propofol injection | 30 minutes | Comfort behavior scale : it incorporates three categories of behavior : Facial expression (0=relaxed ; 1= frowning ; 2=grimacing) ; Verbal response (0=none ; 1= moans ; 2=verbal protest) ; Arm movement (0=none ; 1=medium ; 2=strong). Each scored on a 0-2-point scale so that the total score ranges from 0 to 6. |
| Complications due to anaesthesia | up to 24 hours (from the start of anaesthesia to the patient's discharge of the recovery room) | Occurence of desaturation event (SpO2\< 92%), respiratory distress event (RR\<10 breaths per minute) or bronchospasm. |
| Resumption of walking | 12 hours | Duration between the end of the procedure and the standing position. |
| Health staff satisfaction | 2 hours | Satisfaction VRS ranging from 0 to 4 (0=unsatisfied, 4=very satisfied). |
| Patient satisfaction | 4 hours | Satisfaction VRS ranging from 0 to 4 (0=unsatisfied, 4=very satisfied). |
| Resuming activities of daily living | 24 hours | Numeric scale from 0 to 10 (0=bedridden, 10=resuming total activities). |
