Abstract

This study aims to develop a laryngoscope that can more quickly remove foreign substances in the mouth and perform endotracheal intubation and confirm its usefulness. A laryngoscope suitable for the purpose was manufactured and conducted on 30 fourth-year students at H University. The experimental method was to perform oral suction and endotracheal intubation after inserting a laryngoscope when there was no foreign material, and when there was a foreign material, endotracheal intubation was performed using a laryngoscope with an aspirator attached. When a foreign body was present, suction was performed using the existing method and the developed integrated laryngoscope. The suction time was shorter when the integrated laryngoscope was used than the existing method, and a statistically significant difference was found (p< .000). In the case of the time required for endotracheal intubation, the time required for endotracheal intubation was shorter when the integrated laryngoscope was used than the conventional method, and a statistically significant difference was found (p< .000). The development of an integrated laryngoscope with an aspirator is a useful device that can more effectively remove foreign substances and perform endotracheal intubation when there are foreign substances in the mouth.

본 연구는 입 안에 이물질이 있는 경우 좀 더 신속하게 제거하고 기관내 삽관을 시행할 수 있는 후두경을 개발하고 이에 대한 유용성을 확인하고자 한다. 목적에 맞는 후두경을 제작하고, H 대학 4학년 30명을 대상으로 시행하였다. 실험방법은 이물질이 없는 경우, 이물질이 있는 경우 후두경 삽입 후 입 안흡입, 기관내 삽관 실시의 방법과 흡입기가 부착된 후두경을 사용하여 기관내 삽관을 시행하였다. 이물질이 있는 경우 기존방식과 개발된 일체형 후두경을 사용하여 흡입한 결과 일체형 후두경을 사용한 경우가 기존방식보다 흡입 시간이 단축되며, 통계적으로 유의한 차이가 나타났다(p< .000). 기관내 삽관에 소요되는 시간의 경우 일체형 후두경을 사용한 경우가 기존방식보다 기관내 삽관 시 소요되는 시간이 단축되며, 통계적으로 유의한 차이가 나타났다(p< .000). 흡입기가 부착된 일체형 후두경의 개발은 입 안의 이물질이 있는 경우 좀 더 유용하게 이물질을 제거하고 기관내 삽관을 시행할 수 있는 유용한 장비이다.
