Background: Critical care physician staffing is a crucial element of the intensive care unit (ICU) organization, and is associated with better outcomes in ICUs. Adult ICUs in Korea have been suffering from inadequate full-time intensivists and nurses because of insufficient reimbursement rates (<50% of the original critical care cost) from the National Health Insurance System. Recently, full-time intensivists have been introduced as a prerequisite for adult ICUs of tertiary hospitals in Korea. The purpose of this study was to examine the perception of intensivist staffing among critical care program directors regarding the barriers and solutions when implementing an intensivist model of critical care in Korea. Methods: An email survey of critical care program directors in designated teaching hospitals for critical care subspecialty training by the Korean Society of Critical Care Medicine was performed. The survey domains included vision, culture, resources, barriers, and potential solutions to implementing intensivist physician staffing (IPS). Results: Forty-two critical care program directors were surveyed. A total of 28 directors (66.7%) responded to email queries. Of these, 27 directors (96.4%) agreed that IPS would improve the quality of care in the ICU, although half of them reported a negative perception of relevant clinical colleagues for the role of full-time intensivists and poor resources for IPS in their hospitals. Increased financial burden due to hiring full-time intensivists and concerns regarding exclusion from the management of their critically ill patients in the ICU, together with loss of income for primary attending physicians were stated by the respondents to be major barriers to implementing IPS. Financial incentives for the required cost from the health insurance system and enhancement of medical law relevant to critical care were regarded as solutions to these issues. Conclusions: Critical care program directors believe that intensivist-led critical care can improve the outcome of ICUs. They indicated the financial burden due to IPS and underestimation of a full-time intensivist’s role to be major barriers. The program directors agreed that a partnership between hospital leaders and the Ministry of Health and Welfare was needed to overcome these barriers.

배경: 동맥편만을 이용한 관상동맥 우회술을 위한 한 방법으로 양측성 내흉동맥을 이용한 관상동맥 우회술의 유용성에 대해 알아보고자 하였다. 대상 및 방법: 2000년 1월부터 2001년 12월까지 서울아산병원 흉부외과에서 심폐바이패스를 사용하지 않는 관상동맥 우회술을 시행받은 139명의 환자를 대상으로 의무기록을 이용한 후향적 분석을 시행하였다. 전체환자를 양측성 내흉동맥을 사용한 환자군을 양측 내흉동맥군(bilateral internal thoracic artery; BITA group, n=85), 단일 내흉동맥을 사용한 환자군을 단일 내흉동맥군(single internal thoracic artery; SITA group, n=54)으로 나누었고 수술결과를 비교하였다. 결과: 수술에 따른 사망은 양 군에서 각각 1예씩 발생하였다. 중환자실 재원일 및 퇴원기간은 양 군 간에 차이를 보이지 않았다(BITA군: 2.4±1.7일, 11.2±17.7일, SITA군: 2.8±2.7일, 9.7±7.1일, p>0.05). 문합혈관수는 BITA군이 3.9±0.7개, SITA군이 3.1±0.8개로 BITA군이 더 많았다. 술 후 심근경색은 7예(BITA군 2예, SITA군 5예)에서 발생하였고 심부 흉골감염이 4예(BITA군 3예, SITA군 1예) 발생하여 재수술이 시행되었다. 수술 직후 104명의 환자에서(BITA군 64/85, SITA군 40/54명) 관상동맥 조영술이 시행되었고 좌전하행지로의 문합부위 협착이 4예(BITA군: 2예, SITA군: 2예)에서 관찰되었다. 전체 관찰기간 동안의 문합부위 협착 발생은 총 8예였고 이 중 3명의 환자에서 경피적 관상동맥 성형술이 시행되었으며 관상동맥 우회술을 재시행한 경우는 없었다. 결론: 관상동맥 우회술 시행 시 양측 내흉동맥의 사용은 수술 전후 이환율에서 큰 차이 없이 만족할 만한 개통률을 얻으면서 동맥편만을 이용한 관상동맥 우회술을 가능케 하는 유용한 대안이 될 수 있으리라 생각한다.

이준완,이재원,김종우 대한흉부외과학회 2003 Journal of Chest Surgery (J Chest Surg) Vol.36 No.7

선천성 관상동맥 기형 중 관상동맥 이상기시는 매우 드물게 발생한다. 무증상인 경우도 있지만 실신, 부정맥, 호흡곤란이나 심인성 급사를 일으키기도 한다고 알려져 있다. 저자들은 반복적인 운동 시 실신과 호흡곤란을 주소로 내원한 12세 환아에서 좌관상동맥의 우관상동 기시를 진단하여 관상동맥 이동술(coronary artery transfer)을 시행하여 성공적으로 치험하였기에 관련 문헌과 함께 보고한다.

경피적 관상동맥 중재술 시 골절된 가이드 와이어의 외과적 제거

이준완,김상필 대한흉부외과학회 2006 Journal of Chest Surgery (J Chest Surg) Vol.39 No.8

경피적 관상동맥 중재술 시 사용되는 가이드 와이어의 골절은 드문 합병증이다. 골절로 인하여 관상동맥내에 위치하는 가이드 와이어는 혈관 내막 손상과 혈소판의 응집을 촉발하여 혈전 생성을 야기할 수 있다. 좌전하행지에 위치하여 안정 시 흉통을 유발한 가이드 와이어를 성공적으로 제거하고 관상동맥 우회술을 시행하였기에 보고하는 바이다.

Phrenic Arterial Injury Presenting as Delayed Hemothorax Complicating Simple Rib Fracture

안홍준,이준완,김건동,유인술 대한의학회 2016 Journal of Korean medical science Vol.31 No.4

Delayed hemothorax after blunt torso injury is rare, but might be associated with significant morbidity and mortality. We present a case of delayed hemothorax bleeding from phrenic artery injury in a 24-year-old woman. The patient suffered from multiple rib fractures on the right side, a right hemopneumothorax, thoracic vertebral injury and a pelvic bone fracture after a fall from a fourth floor window. Delayed hemothorax associated with phrenic artery bleeding, caused by a stab injury from a fractured rib segment, was treated successfully by a minimally invasive thoracoscopic surgery. Here, we have shown that fracture of a lower rib or ribs might be accompanied by delayed massive hemothorax that can be rapidly identified and promptly managed by thoracoscopic means.

Feasibility and Early Outcomes of Intensivist-Led Critical Care after Major Trauma in the Korean ICU

김길동,이준완,박형근 연세대학교의과대학 2013 Yonsei medical journal Vol.54 No.2

Purpose: Substantial evidence supports the benefits of an intensivist model of critical care delivery. However, currently, this mode of critical care delivery has not been widely adopted in Korea. We hypothesized that intensivist-led critical care is feasible and would improve ICU mortality after major trauma. Materials and Methods: A trauma registry from May 2009 to April 2011 was reviewed retrospectively. We evaluated the relationship between modes of ICU care (open vs. intensivist) and in-hospital mortality following severe injury [Injury Severity Score (ISS) >15]. An intensivist-model was defined as ICU care delivered by a board-certified physician who had no other clinical responsibilities outside the ICU and who is primarily available to the critically ill or injured patients. ISS and Revised Trauma Score were used as measure of injury severity. The Trauma and Injury Severity Score methodology was used to calculate each individual patient’s probability of survival. Results: Of the 251 patients, 57 patients were treated by an intensivist [intensivist group (IG)] while 194 patients were not [non-intensivist group (NIG)]. The ISS of IG was significantly higher than that for NIG (26.5 vs. 22.3, p=0.023). The hospital mortality rate for IG was significantly lower than that for NIG (15.8% and 27.8%, p<0.001). Conclusion: The intensivist model of critical care is feasible, and there is room for improvement in the care of major trauma patients. Although trauma systems take time to mature, future studies are needed to evaluate the best model of critical care delivery for severely injured patients in Korea.

Objective We investigated whether patients with out-of-hospital cardiac arrest (OHCA) due to an acute myocardial infarction without cardiogenic shock required higher doses of vasopressors with low targeted temperature management (TTM) after return of spontaneous circulation. Methods We included consecutive comatose patients resuscitated from OHCA between January 2011 and December 2013. Patients with return of spontaneous circulation, regional wall motion abnormality on echocardiography, and coronary artery stenosis of ≥70% on percutaneous coronary artery angiography were enrolled. These patients received 36°C TTM or 33°C TTM following approval of TTM by patients’ next-of-kin (36°C and 33°C TTM groups, respectively). The cumulative vasopressor index was compared between groups. Results During induction phase, dose of vasopressors did not differ between groups. In the maintenance phase, the norepinephrine dose was 0.37±0.57 and 0.26±0.91 μg·kg-1·min-1 in the 33°C and 36°C TTM groups, respectively (P<0.01). During the rewarming phase, the norepinephrine and dopamine doses were 0.49±0.60 and 9.67±9.60 mcg·kg-1·min-1 in the 33°C TTM group and 0.14±0.46 and 3.13±7.19 mcg·kg-1·min-1 in the 36°C TTM group, respectively (P<0.01). The median cumulative vasopressor index was 8 (interquartile range, 3 to 8) and 4 (interquartile range, 0 to 8) in the 33°C and 36°C TTM groups, respectively (P=0.03). Conclusion In this study, patients with OHCA due to acute myocardial infarction without cardiogenic shock had an elevated vasopressor requirement with 33°C TTM compared to 36°C TTM during the maintenance and rewarming phases.
