|Acute Coronary Syndrome||Drug: MEOPA and paracetamol Drug: Morphine||Phase 4|
The investigators wish to compare the use of morphine according to current recommendations with the use of MEOPA associated with intravenous paracetamol in the management of patients with STEMI. The investigators hypothesize that the association of MEOPA and paracetamol, which is easy to use in a pre-hospital setting, will give patients pain relief as effectively as morphine.
This alternative treatment would avoid the use of morphine, whose potentially damaging consequences on myocardial function have been suggested by experimental studies and by an observational study. The physician of the mobile emergency team (SMUR) verifies the inclusion and non- inclusion criteria for the study. The patient must present STEMI defined in accordance with the recommendations and chest pain of intensity ≥ 4 on the NRS. The specific treatment for STEMI will be given before inclusion in the study, with the exception of analgesic treatment. In particular, inclusion in the study must not delay the initiation of strategies of recanalization and reperfusion.
The SMUR physician in charge of the patient will administer the treatment defined by randomization.
After 30 minutes, the patient will be managed in accordance with the recommendations and will be hospitalized, generally in a cardiology intensive care unit. At one month, the clinical research technician will record the patient's vital status and collect the patient's hospital records.

Active Comparator: Morphine
Morphine group: administration of morphine will start with a 0.05 mg/kg bolus followed by reinjection of 2 mg every 5 minutes until effective analgesia is obtained, defined as NRS ≤ 3.
Bolus of 2 mg intravenously if EN = 4 or 5 and 3 mg bolus if EN> 6 followed by reinjection of 2mg every 5 minutes until effective analgesia.
Other Name: Morphine Renaudin 1mg/ml
Experimental: MEOPA and paracetamol
The patient will be equipped with a facemask delivering MEOPA.The gas flow received by the patient is adapted to his/her ventilation.
During the same time, an intravenous injection of 1 g paracetamol will be administered.
Drug: MEOPA and paracetamol
The patient will be equipped with a facemask after he/she has been informed. The facemask is adapted to the patient. The patient breathes normally in the mask which is held in place by a member of the SMUR team who has received previous training in use of MEOPA. The gas flow received by the patient is adapted to his/her ventilation.
Other Name: Entonox 170 bar
- Effective analgesia (NRS score≤ 3) at 30 minutes after the start of analgesia [ Time Frame: 30 minutes after randomisation. ]The primary outcome measure is effective analgesia, defined by the consensus conference as an NRS score ≤ 3 at 30 minutes after the start of analgesia.
- Adverse event [ Time Frame: all 5 minutes during 30 minutes ]Occurrence of an adverse effect, in particular, respiratory depression (RR, respiratory rate < 10 cycles par minute or respiratory score ≥ R1), nausea, vomiting, sedation (sedation scale (EDS) score ≥2), dizziness, pruritus.
- NRS distribution [ Time Frame: 30 minutes after randomization ]Distribution of the NRS at 30 minutes and on arrival at the cardiology unit
- Effective analgesia [ Time Frame: all 5 minutes during 30 minutes ]The time of effective analgesia will be defined for each subject
