Learning Curve of VL for Intubation During CPR

Learning Curve of Video-laryngoscope (VL) for First Attempt Successful Endotracheal Intubation During Cardiopulmonary Resuscitation (CPR)

This is a clinical study based on analysis of video-clip data of endotracheal intubation (ETI) using videolaryngoscope (VL) and clinical data for cardiopulmonary resuscitation patients between 2012.03.01.-2015.02.28.

The purpose of this study is to evaluate the appropriate numbers of VL usages for successful ETI at first attempt during cardiopulmonary resuscitation.

Direct layngoscope (DL) is a basic tool for endotracheal intubation(ETI) during cardiopulmonary resuscitation(CPR). ETI during CPR has higher risks of failure or delayed success with frequent attempts, misplacement of the tube, and prolonged interruptions of chest compressions. The main problems associated with ETI relate to the inherently technical difficulty in using DL. VL have various advantages of fast learning curve and overall success comparing with the DL in non-arrest patients, but there was no known data of learnig curve of successful ETI during CPR.

This study tried to estimate the the appropriate numbers of VL usage for successful ETI at first attempt during CPR. So the investigators analyze the success rate, speed, trial number, incidence of complications, and hands-off time of ETI using VL which in real clinical setting. In addition, this study analyze the residency training term, total number of of VL usage using VL at that time.

Inclusion Criteria:

• patients who suffer sudden cardiac arrest and physician tried ti intubate using viseolaryngoscope.

Exclusion Criteria:

• case of requesting the do-not-attempt resuscitation befor ETI
• intubated cases before arrival to emergency department
• physician tried ti intubate using direct-laryngoscope
