Overview
Brief Summary
Prospective single-blind, multicenter, national, randomized, controlled trial in 15 Emergency Department to compare two ways of morphine titration. The eligible patient is included immediately after his arrival in the Emergency Department, after being questioned by the triage nurse about the presence and the intensity of pain, when the VAS is greater than 70 (or EN>7) and after written consent.
After installation into the examination room, patient is randomized in one of two parallel groups (stratified by sex and center using software) and receives one of the two treatments, either inhaled morphine + IV placebo or IV morphine+ inhaled placebo (control group).
In both groups, titration is defined by a dose of repeated boluses as long as the relief is not achieved (VAS> 30 or EN >3) and the criteria to stop titration are not met.
A 5 minutes time interval between the boluses is chosen. Each aerosol takes 5 minutes at a constant air flow, aerosol mask, plastic tubing and PVC transparent tank are used.
Thus patient receives a maximum of 3 aerosol (one aerosol every 10 minutes) and a maximum of 6 IV injections (one injection every 5 minutes) The stopping criteria, except pain relief, are linked to the occurrence of side effects and specific cares are described into the protocol (in case of severe ventilatory depression naloxone titration is provided). Exit criteria from the emergency room and from the hospital are defined. An information sheet is delivered.

Outcomes
Primary Outcomes
Rate of relief obtained or "success rate" at 1 hour from the start of drug administration, and not at the end of titration, such as EVA1 ≤ 30/100 (or EN1 ≤ 3/10).
Time Frame: 1 hour after the initiation of the titration
Rate of relief obtained or "success rate" at 1 hour from the start of drug administration, and not at the end of titration, such as EVA1 ≤ 30/100 (or EN1 ≤ 3/10).
Secondary Outcomes
- Assess the feasibility of an aerosol titration (compliance to the protocol)(From the beginning of the titration until the end of the aerosol titration- within one hour after the start of the titration)
- Safety-Proportion of Sleepy patients (Ramsay score = 3) (adverse events)(Until 3hours after the end of the titration)
- Evaluate antalgic efficacy criteria(2hours after the initiation of the titration)
- Safety- Proportion of serious adverse events in each arm(Until 3hours after the end of the titration)
- Safety- incidence of minor side effects in each arm of which neurovegetative usually known and related to opiates (nausea, vomiting, urine retention, ...)(Until 3hours after the end of the titration)
- Evaluate antalgic efficacy criteria(From the beginning of the titration until the end of the titration- assessed within one day)
- Evaluate antalgic efficacy criteria(From the beginning of the titration until the end of the titration- assessed up to one day)
- Evaluate antalgic efficacy criteria(30 minutes after the initiation of the titration)
- Evaluate antalgic efficacy criteria(1hour after the initiation of the titration)
