Prehospital airway management is a key component of emergency responders and remains an important task of Emergency Medical Service (EMS) systems worldwide. The most advanced airway management techniques involving placement of oropharyngeal airways such as the Laryngeal Mask Airway or endotracheal tube. Endotracheal tube placement success is a common measure of out-of-hospital airway management quality. Regional variation in regard to training, education, and procedural exposure may be the major contributor to the findings in success and patient outcome. In studies demonstrating poor outcomes related to prehospital-attempted endotracheal intubation (ETI), both training and skill level of the provider are usually often low. Research supports a relationship between the number of intubation experiences and ETI success. National standards for certification of emergency medicine provider are in general too low to guarantee good success rate in emergency airway management by paramedics and physicians. Some paramedic training programs require more intense airway training above the national standard and some EMS systems in Europe staff their system with anesthesia providers instead. ETI remains the cornerstone of definitive prehospital airway management, However, ETI is not without risk and outcomes data remains controversial. Many systems may benefit from more input and guidance by the anesthesia department, which have higher volumes of airway management procedures and extensive training and experience not just with training of airway management but also with different airway management techniques and adjuncts.

5. Prospective, comparative, randomised study during 6 months.
Methods:
Prospective, comparative, randomised study during 6 months.
Tracheal intubation was attempted by an emergency doctor with extensive experience. Patients were randomly allocated to one of two groups, direct (DL)laryngoscopy vs Mcgrath group(MG).
This study was performed to compare DL with MG in terms of time to intubation (TTI), number of attempts and complications and use of difficult intubation equipment.
Descriptive analysis of : indications, difficult airway predictors, success, times tu success and complications.

10. Study sample is representative of people intubated in IMU in France.
Discussion :
Study sample is representative of people intubated in IMU in France.
This study, which compares DL with MG, demonstrates that MG is not superior.
On the other side, TTI and complications are comparable in number while there is more patients with difficult airway predictors in MG group.
There is no oesophagial intubation in MG group.
This study had several limitations : selection bias and a lack of potency.

11. Conclusion :
This study can’t demonstrate the Mac Grath© is superior to DL in terms of TTI and number of attempts.
The Mac Grath© place remains to be definied in emergency medicine.
