Comparison of differences in ventilation volume according to fixation method of I-gel during cardiopulmonary resuscitation in hospital: a study using a simulation manikin

ABSTRACT

Objective@#The I-gel device and endotracheal tube are used for advanced airway management during cardiopulmonary resuscitation (CPR). This study compares differences in the ventilation volume according to the fixation methods (tape and band) of I-gel using a simulation manikin. @*Methods@#I-gel was placed in an advanced life support simulator and fixed with either tape or band fixation, and an endotracheal tube was inserted using an endotracheal tube holder (AnchorFast). CPR was performed according to the 2020 Korean CPR guidelines, using a mechanical chest compression device (LUCAS) and an adult bag. CPR was performed for 30 minutes. Positional shifts of the I-gel and endotracheal tube and differences in the ventilation volume on the simulation manikin were subsequently measured. Five trials were carried out in each setting. Statistical analysis was carried out using SPSS version 27.0. A P-value <0.05 is considered significant. @*Results@#The following positional shifts were obtained after 30 minutes of CPR I-gel tape fixation, 4.96±0.72 mm; I-gel band fixation, no change; endotracheal tube holder, no change. The mean ventilation volumes obtained were 504.43± 14.42, 536.86±5.56, and 528.38±8.81 mL, respectively. @*Conclusion@#Our results indicate that the use of I-gel is as effective as an endotracheal tube for initial airway maintenance during CPR in the hospital. We recommend using an elastic band-type fixation device for the fixation method.
