Bolus Vasopressor Use for Air Medical Rapid Sequence Intubation: The Vasopressor Intravenous Push to Enhance Resuscitation Trial

by

Daniel P. Davis, MD; David Olvera, BA, NRP, FP-C, CMTE; William Selde, MD; John Wilmas, MD; David Stuhlmiller, MD Abstract Background Rapid sequence intubation (RSI) may compromise perfusion because of the use of sympatholytic medications as well as subsequent positive pressure ventilation. The use of bolus vasopressor agents may reverse hypotension and prevent arrest. Methods […]

The Optimal Preoxygenation Target to Avoid Desaturation During Pediatric Rapid Sequence Intubation

by

Jennifer Noce BA, NRP, CCEMTP, FP-C, CCP-C David Olvera BA, NRP, FP-C, CMTE Daniel Davis MD Abstract Background: Rapid sequence intubation (RSI) is a critical procedure in the resuscitation of critically ill and injured patients but carries an important risk of oxygen desaturation. In the adult population, a target preoxygenation threshold of >93% has been […]

Air Medical Administration of Whole Blood Versus Packed Red Blood Cells for Trauma Patients

by

Leslie Brown, BS, FP-C, TP-C, NRP; Daniel P. Davis, MD; Kaitlyn Price, BSN, RN, CFRN, TCRN; Laura Smith, BSN, RN, CFRN, CEN, EMT-P — Air Methods Corporation Abstract Background: Early blood administration is associated with improved survival from traumatic shock, but the use of whole blood (WB) versus packed red blood cells (PRBCs) remains controversial. […]

Hemodynamics in Helicopter Emergency Medical Services (HEMS) Patients Undergoing Rapid Sequence Intubation With Etomidate or Ketamine

by

Scott Kunkel; Timothy Lenz Abstract Background: Rapid sequence intubation (RSI) is performed by helicopter emergency medical services (HEMS) providers to establish airway control. Common induction agents are etomidate and ketamine, both touted to have relatively stable hemodynamic profiles. Limited data comparing these medications in the air medical setting exist. Objective: Compare administration of ketamine and […]

Compliance and Attitudes of Critical Care Transport Providers Regarding a Prehospital Rapid Sequence Intubation Checklist

by

David Olvera, BA, NRP; Michael J. Lauria, MD, NRP, FP-C; Jennifer Noce, NRP, CCEMTP, FP-C, CCP-C; William B. Weir, MD, FAAEM, FACEP, FAEMS Abstract Human factors engineering innovations, such as checklists, have been adopted in various acute care settings to improve safety with reasonable compliance and acceptance. In the air medical industry, checklists have been […]

Examination of Primary Bougie Use in Air Medical Intubations

by

Thomas Crain, BSN, RN, CFRN FP-C; Daniel Davis, MD, FACEP; Darrin Buchta, BS, NRP, FP-C, MTSP-C — Air Methods Corporation Introduction: Use of a bougie during emergency rapid sequence intubation (RSI) appears to increase first attempt success but may increase time to a definitive airway. This analysis was performed to explore primary use of a […]

First pass success is important in prehospital tracheal intubation to minimize the risk of physiologic deterioration.

by

D.Olvera – A.Patanwala – A. Wolfe Jr. – J. Sakles Abstract Pre-hospital tracheal intubation of the critically ill and injured can be challenging and patients are at risk of serious complications. The purpose of this study was to determine the association between the number of intubation attempts and the occurrence of physiologic deterioration. This institutional […]

The Use of Ketamine for Air Medical Rapid Sequence Intubation Was Not Associated With a Decrease in Hypotension or Cardiopulmonary Arrest

by

Rapid sequence intubation (RSI) is associated with a number of complications that can increase morbidity and mortality. Among RSI agents used to blunt awareness of the procedure and produce amnesia, keta-mine is unique in its classification as a dissociative agent rather than a central nervous system depressant. Thus, ketamine should have a lower risk of peri-RSI hypotension because of the minimal sympatholysis com-pared with other agents.

Prehospital Blood Glucose Testing as a Predictor of Impending Hypotension in Adult Trauma Patients
