Trial Outcomes & Findings for Observational Study of Rapid Sequence Intubation Drug Delivery Using Intraosseous and Intravenous Access. (NCT NCT01486407)

Race and Ethnicity were not collected from any participant.

Time measured in seconds from first drug delivery to the time of operator-perceived sufficient relaxation to perform endotracheal tube placement

Intubation Difficulty Scale (IDS) provides a numerical Total score describing the difficulty of the intubation procedure based upon the summation of the following individual sub-scores: number of attempts (each additional attempt adds (+)1 point, minimum score=0, no maximum), number of operators (each additional +1 point, minimum score=0, no maximum), use of alternative techniques (each alternative technique +1 point, minimum score=0, no maximum), cormack grade for first oral attempt (measures the quality of the view of the larynx using grades 1 - 4 where higher number means poorer visibility; successful blind intubation=0. minimum score=0, maximum=4), lifting force required (normal=0 or increased=1), laryngeal pressure (not applied=0 or applied=1), vocal cord mobility (abduction=0 or adduction=1). Total IDS minimum score=0, no maximum score. Score 0=Easy; Score 1 - 5 =slight difficulty; Score \>5 =moderate to major difficulty Score infinite =Failed/Impossible intubation

Operator reported level of satisfaction with intubating conditions regarding adequacy of sedation and adequacy of muscular relaxation. This is reported using a 100 mm visual analog scale from 0 - 100 where higher numbers indicate greater satisfaction.

Failure rate of endotracheal intubation and requirement for alternative airway management methods

Incidence of short-term catheter related complications for each technique (IO vs IV)
