Matthew Hansen, M.D., awarded K23 grant

Matthew Hansen, M.D.

Matthew Hansen, M.D., was recently awarded a K23 grant from the National Heart, Lung, and Blood Institute for his study, "Improving the Safety and Efficacy of Out-of-Hospital Pediatric Airway Management."

The overall objective of Dr. Hansen's study is to test whether supraglottic airway devices are superior to endotracheal intubation and bag-valve-mask ventilation for out-of-hospital pediatric airway management. Endotracheal intubation, a complex and invasive procedure, is the single most common out-of-hospital advanced airway technique and the gold standard in the hospital. However, up to 50% of out-of-hospital pediatric endotracheal intubations are complicated by endotracheal tube misplacement and/or dislodgement, hypoxia, hypercapnia, or damage to airway structures. Bag-valve-mask ventilation is less invasive but challenging in the out-of-hospital environment given the need to provide care in a moving vehicle. There is critical need for a new approach that reduces complications and is effective in oxygenation and ventilation. The central hypothesis of this study is to understand whether supraglottic airway devices, commonly used in children in the operating room, are more effective than endotracheal intubation and bag-valve-mask ventilation for out-of-hospital emergency airway management. To test this hypothesis Dr. Hansen will examine the efficacy of supraglottic airway devices being used by paramedics in simulation lab and operating room environments; conduct a qualitative study to understand the decision making process used in out-of-hospital pediatric airway management and identify potential barriers to implementation of supraglottic airway devices; and conduct a prospective observational study to determine how the airway management strategy affects CPR quality and medication administration in pediatric out-of-hospital cardiac arrest. This research will help improve out-of-hospital pediatric airway management by helping understand how individual device characteristics, provider factors, and clinical context affect the efficacy and safety of airway management techniques.

Research is supported by the National Heart, Lung, and Blood Institute of the National Institutes of Health under Award Number K23HL131440

Dr. Hansen joined the Department of Emergency Medicine at OHSU as faculty in 2012. Dr. Hansen completed residency training in Emergency Medicine and a fellowship in Pediatric Emergency Medicine, both at OHSU. He is currently a K12 Scholar and Assistant Professor in the Center for Policy and Research in Emergency Medicine. His research interests focus on resuscitation and stabilization of ill and injured children in the prehospital setting with a specific emphasis in pediatric airway and respiratory management in the prehospital setting.
