Multicenter Study
Factors associated with tracheal intubation-related complications in the prehospital setting: a prospective multicentric cohort study.
Background Emergency tracheal intubation is routinely performed in the prehospital setting. Airway management in the prehospital setting has substantial challenges. Objective The aim of the present study was to determine risk factors predicting tracheal intubation-related complications on the prehospital field. ⋯ In the multivariate analysis, we found that the leading risk factors for tracheal intubation-related complications were Cormack and Lehane grade 3 and 4 [odds ratio (OR) = 1.65; 95% confidence interval (CI), 1.05-2.61; and OR = 2.79; 95% CI, 1.56-4.98, respectively], a BMI of more than 30 (OR = 1.61; 95% CI, 1.13-2.28), when intubation was difficult (OR = 1.72; 95% CI, 1.15-2.57), and when tracheal intubation required more than one operator (OR = 2.30; 95% CI, 1.50-3.49). Conclusions In this prospective study, we found that Cormack and Lehane more than grade 2, BMI >30, difficult intubation, and tracheal intubation requiring more than one operator were all independent predictors of tracheal intubation-related complications in the prehospital setting. When these risk factors are identified on scene, adapted algorithms that anticipate the use of a bougie should be generalized to reduce morbidity on the prehospital field.

Multicenter Study
Comparison of seven prehospital early warning scores to predict long-term mortality: a prospective, multicenter, ambulance-based study.
A prospective, multicenter, ambulance-based study of adult patients with an acute illness involving six advanced life support units and 38 basic life support units, referring to five emergency departments in Spain. ⋯ Among seven tested EWS, the use of the MREMS presented better characteristics to predict 1-year mortality; however, all these scores present moderate performances.
