Summary

MEOPA (Equimolar Oxygen-Nitrogen Protoxide Mix) is a gas used in emergencies for short-term painful acts. It is often very effective with an analgesic, anxiolytic and muscle relaxant action. It is often combined with other analgesic medicines. It has already been proven in emergency medicine for short-term pain and trauma. It seems that it could be used more particularly for pains of medical origin. A study has already proved its effectiveness in the treatment of migraines in emergencies. The first phase of the NEPHROPAIN study began in 2016 after a favorable opinion from the Regional Ethics Committee. NEPHROPAIN phase AVANT was a prospective non-interventional study on the use of analgesic drugs in nephritic colic in emergencies by Dr. Alexandre Tanneau. This study was conducted at the University Hospital of Rennes and included 60 patients admitted to the emergency department for suspected renal colic. It made it possible to recruit the control group of the NEPHROPAIN study. Its main objective was to describe the suspected population of renal colic in Rennes emergencies, to determine NEPHROPAIN's primary endpoint and the number of NEPHROPAIN needed subjects.
