본 연구는 이동 중 구급차에서 응급구조사의 삽관자세 변화에 따른 시야의 높이 변화가 기관내 삽관의 신속성에 영향을 미치는지 비교하고 환자의 삽관자세 변화가 기관내 삽관의 신속성에 영향을 미치는지 분석하여 심정지 및 외상성 응급 환자에게 효과적인 전문기도관리를 시행하는데 목적이 있다. 연구대상은 C도 13개 소방서에 근무하고 있는 1급 응급구조사 60(대조군30명, 실험군30명)명을 편의추출하여 시행하였으며, 자료 분석은 SPSS WIN 14.0 Version을 사용하여 하였다. 연구결과 전문기도관리의 신속성 향상을 위해서는 환자의 냄새맡기 자세와 주들것과 응급구조사 시트 사이 공간에서의 기관내 삽관이 효과적일 것으로 사료되고 실험 후의 삽관 자신감이 유의하게 상승 하였으므로 전문기도관리의 효율성 향상을 위해서는 구급차 내에서의 삽관자세와 방법에 대한 지속적인 교육(훈련)이 필요할 것으로 사료된다.

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.

Purpose : This research was designed to provide basic data for advanced pre-hospital airway management by comparing the ease of intubation, the success rate and the time for intubation performed with Macintosh Laryngoscope, Gum Elastic Bougie and Pentax AirWay Scope on the floor and table. Methods : Intubation was performed 30 times in total, including 5 times for each of intubation using Macintosh Laryngoscope, Gum Elastic Bougie and Pentax Airway Scope on the table and floor, only on subjects who passed the practice test of the national exam for paramedics. Data were collected by measuring the ease of intubation, the success rate and the time for intubation, and then analyzed by descriptive analysis, paired t-test, ANOVA using SPSS 18.0. Results : 1. There was a significant difference in the ease of intubation according to intubation devices. 2. There was a significant difference in the ease of intubation according to table height for intubation. 3. There was a significant difference in the success rate according to intubation devices. 4. There was no significant difference in the success rate according to table height for intubation. 5. There was a significant difference in the intubation time according to intubation devices. 6. There was a partially significant difference in the intubation time according to table height for intubation. Conclusion : Sufficient training not only with Macintosh Laryngoscope but also with Gum Elastic Bougie and Pentax Airway Scope could improve the survival rate by intubation in patients with difficult airway.

본 연구는 성문위기도기 인후두 튜브(Supraglottic Airway Laryngopharyngeal Tube, SALT)와 직접 후두경을 이용하여 어려운 자세에서 기관내삽관의 신속성과 자신감, 용이성 등을 비교하여 전문기도관리 시행 능력을 향상 시키는데 있다. 연구대상은 J도 소방서에서 근무하고 있는 1급 응급구조사 30명을 대상으로 무작위 교차방법(Randomized crossover design)으로 디자인한 실험연구로 자료 분석은 SPSS 20.0 Version을 사용하였다. 어려운 자세에서 SALT를 이용한 기관내삽관은 직접 후두경을 이용한 기관내삽관 보다 신속성에서 유의한 차이를 보였으며(p<.001), 자신감과 용이성에서도 유의한 차이를 나타냈다(p<.001). 직접 후두경을 사용한 기관내삽관이 어려운 환경이나 외상환자의 경우 SALT를 이용한다면 안전하고 신속한 삽관을 할 수 있을 것이다. 또한 전문기도관리의 효율성 향상을 위해서 국내 현장에 SALT의 도입이 필요 할 것으로 사료된다.

Objective: This study examined the initial partial pressure of carbon dioxide ($PCO_2$) as a possible indicator of prehospital ventilation and its association with prehospital i-gel in out-of-hospital cardiac arrest (OHCA) patients. Methods: The demographics and arrest parameters, including i-gel insertion and initial arterial blood gas analysis, of OHCA patients who visited the emergency department were analyzed retrospectively. Linear regression analysis was performed to examine the association between i-gel insertion and the initial $PCO_2$. Results: A total of 106 patients were investigated. Fifty-six patients had prehospital i-gel insertion and 50 patients did not have a prehospital advanced airway. The initial $PCO_2$ was higher in the i-gel group than the no advanced airway group (105.2 mmHg [77.5-134.9] vs. 87.5 mmHg [56.8-115.3], P=0.03). Prehospital i-gel insertion was associated with a higher initial $PCO_2$ level (${\beta}$ coefficient, 20.3; 95% confidence interval, 2.6-37.9; P=0.03). Conclusion: Prehospital insertion of i-gel was associated with higher initial $PCO_2$ values in OHCA patients compared to no advanced airway.

Purpose: Effective time management, as well as life-saving care, are important in maximizing the prognosis of patients who have sustained major traumas. This study evaluated the appropriateness of emergency medical system (EMS) provider's essential care and how this care impacted on-scene time in patients with major traumas. Methods: This retrospective observational study analyzed the EMS major trauma documents, classified according to the physiological criteria (Glasgow coma scale <14, systolic blood pressure <90mmHg, Respiration rate <10 or >29) in Daejeon, from January, 2015 to December, 2018. Results: Of the 707 major trauma cases, the mean on-scene time was 7.75±4.64 minutes. According to EMS guidelines, essential care accuracy was 67.5% for basic airway, 36.4% for advanced airway, 91.2% for cervical collar, 81.5% for supplemental oxygen, 47.0% for positive pressure ventilation, 19.9% for intravenous access and fluid administration, and 96.0% for external hemorrhage control. Factors affecting on-scene time were positive pressure ventilation (p<.004), and intravenous access and fluid administration (p<.002). Conclusion: Adherence to guidelines was low during advanced airway procedures, positive pressure ventilation, intravenous access, and fluid administration. In addition, the on-scene time was prolonged when the practitioner provided positive pressure ventilation, intravenous access, and fluid administration; however, these durations did not exceed the recommended 10 minutes.

Dental treatment under general anesthesia is considered a good way for behavioral control in disabled patients. General anesthesia for disabled patients sometimes requires difficult airway management. In this case, intra-oral camera is great helpful to intubation. Originally, the intra-oral camera is designed to facilitate diagnosis dental disease. The intra-oral camera is very efficient on intubation. Laryngeal photo taken by Intra-oral camera can be good guide for difficult intubation. In this report, an 11-year-old boy with chromosomal anomaly received dental care under general anesthesia. And he had a potentially difficult airway. We achieved nasotracheal intubation successfully with intra-oral camera.

본 연구의 목적은 주행 중인 구급차에서 기관내 삽관과 후두마스크(LMA) 삽입의 신속성과 성공률을 비교하여 구급대원의 전문기도관리 능력을 향상시키는 데 있다. 연구방법은 C 지역 구급대원 중 1급 응급구조사 60명(대조군 30명, 실험군 30명)을 편의추출 하여 마네킹을 대상으로 측정을 하였다. 자료 분석은 SPSS WIN 14.0 Version을 사용하였다. 연구결과 기관내 삽관이 냄새맡기 자세에서 신속성이 좋은 것으로 나타났고(t=-4.038, p<.001), 중립자세에서 그룹 간 신속성 차이는 없었으나 기관내 삽관 시 16명(53.3%)에게 치아파절이 발생했다. 또한, 그룹 간 성공률 차이는 없었고 두 그룹 모두 실험 후 자신감이 향상된 것으로 나타났다. 결론적으로 냄새맡기 자세가 불가능한 외상성 환자는 후두마스크(LMA)의 사용이 효과적이고 구급대원의 기도관리 능력을 향상시키기 위하여 지속적인 교육이 필요할 것으로 사료된다.

Programs provided by the Korea Association of Cardiopulmonary Resuscitation include Basic Life Support (BLS), Advanced Cardiac Life Support (ACLS), Pediatric Advanced Life Support (PALS), and Korean Advanced Life Support (KALS). However, programs pertinent to dental care are lacking. Since 2015, related organizations have been attempting to develop a Dental Advanced Life Support (DALS) program, which can meet the needs of the dental environment. Generally, for initial management of emergency situations, basic life support is most important. However, emergencies in young children mostly involve breathing. Therefore, physicians who treat pediatric dental patients should learn PALS. It is necessary for the physician to regularly renew training every two years to be able to immediately implement professional skills in emergency situations. In order to manage emergency situations in the pediatric dental clinic, respiratory support is most important. Therefore, mastering professional PALS, which includes respiratory care and core cases, particularly upper airway obstruction and respiratory depression caused by a respiratory control problem, would be highly desirable for a physician who treats pediatric dental patients. Regular training and renewal training every two years is absolutely necessary to be able to immediately implement professional skills in emergency situations.
