Purpose : The present study was designed to provide basic data for advanced pre-hospital airway management by comparing the insertion time and success rate between laryngeal tube suction II (LTS II) and laryngeal mask airway (LMA) in a manikin. Methods : A total of 32 participants were novice users to both of devices among paramedic students. After taking the introductory lecture and demonstrations, the participants made an attempt to insert the LTS II and LMA to compare the insertion time and success rate. They marked the easiness of insertion of the score ranged from 1 to 10 score scale and preference of the two devices. Results : The insertion time of the LTS II was significantly shorter than that of the LMA (p =.000). There was no significant difference between LTS II and LMA in the success rate. In the easiness of insertion, the score of LTS II $(8.47{\pm}1.41score)$ was significantly higher than that of LMA $(7.19{\pm}1.98score)$(p =.001). The preference of LTS II (75%) was much higher than that of LMA (25%). Conclusion : The manikin study data showed that the LTS II may be a good alternative airway device for providing and maintaining a patent airway.

A laryngeal mask airway (LMA) has many advantages in the management of airway emergencies or the treatment of patients in whom intubation is difficult, but the use of LMA during positive ventilation may seem inappropriate to protect the airway because of the risk of pulmonary aspiration of regurgitated gastric contents. We experienced aspiration pneumonia after general anesthesia using LMA in patient who suffered from panperitonitis. It is considered that the main reason for aspiration pneumonia was a leakage of gastric content through the space surrounding the nasogastric tube while under high airway inflation pressure. We concluded that when LMA or the Proseal laryngeal mask airway (PLMA) is chosen for the use in difficult intubations, careful patient-suitability selection and the correct knowledge of LMA and PLMA are needed to protect the airway against aspiration.

이 연구는 소방 119구급대에서 근무하는 1급 응급구조사의 병원임상수련 실태를 조사한 연구이다. 조사대상은 소방에 근무하는 1급 응급구조사 42명으로 하였으며, 2012년 5월 11일부터 2012년 5월 12일까지 구조화된 무기명 자기기입식 설문지를 이용한 설문조사에 의하였다. 연구결과 1급 응급구조사의 업무범위를 한 번 이상 직접 경험한 경우는 56.5 %였고, 이들 중 기관내삽관 66.9 %, 후두마스크 8.4 %, 정맥로확보 76.6 %, 니트로글리세린 설하투여 61.2 %, 기관지확장제 흡입 50.0 %, 수액투여 73.8 %, 인공호흡기 사용 57.6 %, 포도당 주입 57.6 %를 경험하였으며, 1급 응급구조사 업무범위를 16개 의료기관별로 살펴본 결과 58.0 %가 한 번 이상 직접 경험하였다. 향후 1급 응급구조사의 교육 요구도에 대한 지속적 연구가 필요하며, 병원임상수련의 문제점 분석, 임상실습지침서의 보완과 실무중심의 교육프로그램 운영 및 관리에 대한 규정과 지속적인 평가가 필요하다.

Despite the laryngeal mask airway (LMA) has been widely used in anesthesia, its use is rare in the field of dentistry. Placing LMA in the oral cavity may interrupt dental treatment. However, there are some circumstances in which LMA is more advantageous than tracheal intubation for managing the airway. Especially, the reinforced LMA has a flexible tube shaft, rendering it more accessible for dental treatment. We report a case of dental treatment of a 3-year-old patient with hypoplastic left heart syndrome combined with pulmonary hypertension using reinforced LMA for airway management under general anesthesia. We also discuss the considerations of utilizing the reinforced LMA for dental treatment.

심정지 또는 중증 외상 환자의 신속한 기도유지는 매우 중요하다. 본 연구의 목적은 후두튜브(LTS)와 후두마스크(PLMA)의 삽관 속도, 성공률, 교육 전 후 자신감 변화를 비교하여 병원 전 단계의 주축을 담당하고 있는 119구급대의 전문기도관리 능력을 향상 시키는데 있다. 연구 대상자는 119구급대원 중 1급 응급구조사 60명(LTS군 30명, PLMA군 30명)이며 마네킹을 대상으로 5분간 3회 실습 후 삽관 소요시간과 성공 여부, 자신감 변화를 측정하였다. 연구결과 LTS와 PLMA를 이용한 삽관 시간은 유의한 차이를 보였고(p=.000), 성공률은 유의한 차이가 없으며, 실험 후 자신감은 유의하게 상승하였다(p=.000). 결론적으로 경추가 고정되고 혀 부종이 있는 외상환자에게 신속한 삽관이 필요한 경우 LTS 사용이 효과적이며 교육을 통하여 전문기도관리 능력을 향상시킬 수 있을 것으로 사료된다.

Purpose: The purpose of the study was to investigate the effects of laryngeal mask airway (LMA) insertion from different positions, using different methods, on the quality of the insertion, for identifying a more convenient and effective insertion method. Methods: In a model ambulance, 30 paramedic students performed the LMA insertion procedure, in four different settings, combinations of the rescuer's position (at the head end of the patient, at the side of the patient), and insertion technique (index finger insertion, thumb insertion), in a randomized order. Quality of insertion index and convenience of use were measured. Results: The quality of insertion index (tidal volume, gastric insufflation, airway pressure, airway sealing pressure, midline positions, insertion success grade, and insertion time) were not significantly different among four different settings. However LMA insertion from the anterior (head) end, using the index finger method compared to the thumb method was found to be significantly more convenient. Conclusion: We recommend using the more convenient and familiar LMA insertion method, between index finger insertion and thumb insertion, regardless of rescuer's position.
