A pilot study of the King LT supralaryngeal airway use in a rural Iowa EMS system

چکیده
INTRODUCTION In 2003, the King Laryngeal Tube (LT) received FDA approval for US sales. Prehospital systems in urban setting have begun evaluating and adopting the LT for clinical airway management. However, it is not routinely approved by State EMS Boards for use by all prehospital providers. Given the LT's simple design there may be benefit to using this tool for airway management in all levels of prehospital providers. This pilot study reviews cases where the King LT was used in a rural Iowa county EMS system. METHODS In 2006, the Iowa Department of Public Health / Bureau of EMS approved a 12 month pilot evaluating the King LT by all levels of EMS providers in a rural county EMS system. Following a didactic and competency training session on using the King LT, the providers were instructed to continue airway management per usual protocol but were allowed to use the King LT as a first line airway tool if they felt indicated. Successful placement of airway devices used were determined by colourimetric end-tidal CO2, chest auscultation and rise as well as vital sign and skin colour improvement. Review of the data was approved by the University of Iowa Institution Review Board (IRB). RESULTS During the 12-month pilot period, the King LT was used in 13 patients with a mean age of 60.7 years (24-81). All patients had cardiopulmonary or traumatic arrest. The King LT was successfully placed on the first attempt in all but one case. The King LT was placed following endotracheal intubation failure in 6/13 (46.1%) cases and in 3/13 (23.1%) of cases of Combitube attempt / failure. CONCLUSIONS This small pilot project emphasizes the need for additional rapid airway management tools given the demonstrated ETI failures. The authors believe the King LT has significant potential to impact prehospital airway management as a primary airway device or backup to other failed strategies. Further study is necessary to evaluate the LT's efficacy compared to current strategies.

INTRODUCTION The ever-present risk of mass casualties and disaster situations may result in airway management situations that overwhelm local emergency medical services (EMS) resources. Endotracheal intubation requires significant user education/training and carries the risk of malposition. Furthermore, personal protective equipment (PPE) required in hazardous environments may decrease dexterit...

BACKGROUND Airway management is a key component of prehospital care for seriously ill and injured patients. Oral endotracheal intubation (OETI) is the definitive airway of choice in most emergency medical services (EMS) systems. However, OETI may not be an approved skill for some clinicians or may prove problematic in certain patients because of anatomic abnormalities, trauma, or inadequate rel...

OBJECTIVES Previous reports have shown a high rate of ventilation failure via direct laryngoscopy as compared with the King LT-D airway. This difference is further divergent in the pediatric population. The goal of this study was to compare the difference in efficacy of ventilation by prehospital providers in a simulated environment between direct laryngoscopy and Pedi-King LT-D. METHODS In t...
