목적: 최근 미숙아에서 동맥관 결찰 술 후 설명할 수 없는 혈역동학적 불안정성에 대한 보고가 되고 있어 극소저체중아에서 동맥관 결찰술 후 발생하는 혈역동학적 불안정성의 위험 요인 및 임상 양상에 대해 알아보고자 하였다. 방법: 2002년 1월부터 2008년 12월까지 고려대학교 의료원내 3개 병원의 신생아 중환자실에서 치료 받은 재태 32주 미만의 극소저체중출생아에서 동맥관 결찰술을 시행 받은 환아 18명을 대상으로 하여 의무기록을 후향적으로 조사, 분석하였다. 수술 중 또는 수술 후 문제로 인한 혈역동학적 불안정성 이외에 설명할 수 없는 심폐 기능의 저하로 인공 호흡기 의존도의 증가와 혈압의 하강 등이 관찰된 환자를 혈역동학적 불안정군(hemodynamic instability group, HI)으로 정의하였다. 결과: 연구에 참여한 18명의 환아들의 재태 주수는 $27^{+6}{\pm}1^{+6}$주, 평균 출생 체중은 951${\pm}$245 g이었다. HI군은 7명(7/18, 39%)이었으며 혈역동학적 안정군(hemodynamic stability group, HS)은 11명(11/18, 61%)이었다. HS군에 비해 HI군은 출생 체중(1,033${\pm}$285 g vs. 821${\pm}$126 g, P=0.048)과 수술 시 체중(1,195${\pm}$404 g vs. 893${\pm}$151 g, P=0.042)이 작았으며, 재원기간이 길었고 (105${\pm}$29 vs. 141${\pm}$39, P=0.038) 심한 기관지 폐 이형성증의 빈도가 높았고(no/mild/moderate/severe, 2/5/2/2 vs. 0/1/2/4, P=0.038) 수술 전 $FiO_2$의 농도가 높았다(0.29${\pm}$0.06 vs. 0.38${\pm}$ 0.09, P=0.02). 18명 중 HS군에서 1명의 환아가 동맥관 결찰술 후 94일 째 패혈증으로 사망하였다. 결론: 극소저체중아에서 동맥관 결찰술 후 혈역동학적 불안 정성이 발생한 경우는 약 39%였다. 작은 출생 체중과 수술 시 체중, 수술 전 높은 산소 분압의 산소 투여가 동맥관 결찰술 후 혈역동학적 불안정성 발생의 위험인자가 될 수 있으며 아울러 혈역동학적 불안정성은 기관지 폐 이형성증의 유병률 및 중증도와 재원기간을 증가시킬 수 있음을 확인하였다.

During the closure of the sternum, following the mitral valve replacement for mitral stenoinsufficiency, hemodynamic instability with cardiac tamponade was developed. After transfusion of massive diuretics and albumin for a few times, reclosure of the sternum was attempted with development of hemodynamic instability. And so we decided delayed sternal closure. After 72 hours of mitral valve replacement, delayed sternal closure was done with success, and so we report this case with literatures.

Pelvic bone fracture with hemodynamic instability is fatal and the mortality rate can range up to 40%. Despite the big advances in the treatment of massive bleeding and hemorrhagic shock, the mortality associated with hemodynamically unstable pelvic bone fractures remains high. The gold standard of treatment for pelvic bone fracture with hemodynamic instability has not yet been determined and is an issue of main discussion among many doctors. Retroperitoneal packing is not yet wide spread in Korea, but is a good modality for managing of massive bleeding from pelvic bone fractures when an angiography suite or an expert surgeon is not available. A vacuum-assisted closure (VAC) system can also be applied with retroperitoneal packing in the manner of damage control surgery and open abdomen surgery. We present the case of a 51-year-old male who had a pelvic bone fracture with massive bleeding. We performed retroperitoneal gauze packing with a VAC system for the first time. The postoperative vital signs of patient were immediately stable, the massive bleeding was easily and quickly controlled, and the amount of transfusion of blood components was reduced.

A Morel-Lavallée lesion is a closed degloving injury caused by traumatic separation of the skin and subcutaneous tissue from the underlying fascia. However, since physicians tend to focus on treating the bone fracture, hemodynamic instability accompanying a Morel-Lavallée lesion can sometimes be overlooked. We report the case of a hemodynamically unstable 73-year-old man who had a Morel-Lavallée lesion of the thigh, but no femur fracture. Angiography showed active bleeding from the muscular branch of the right deep femoral artery, which was then successfully embolized.

Purpose: Treatment and prognosis in patients with pelvic bone fracture depend on the characteristics of the fracture and the stability of the pelvic ring. The purpose of this study is to analyze the characteristics of and the relationships between fracture patterns, injury mechanisms, clinical courses, and prognoses according to the hemodynamic pattern. Methods: Between January 2004 and September 2006, 89 patients under diagnosis of pelvic bone fracture were retrospectively analyzed on the basis of medical records and radiologic examinations. Patients with confirmed hemorragic shock with a systolic pressure of less than 90 mmHg were defined as the shock group. Young's classification was used to characterize fracture patterns. Factors relating to the clinical manifestation and to treatments such as transfusion and surgery were analytically compared. Results: The mean age of the patients was $48.8{\pm}18.7$, among which 49 (55.1%) were male. The numbers of shock and non-shock patients were 35 (39.3%) and 54 (60.7%) respectively. Eighteen (51.4%) of the shock patient had injuries resulting from pedestrian accidents (p=0.008). According to Young's classification, lateral impact fractures amounted to 20 and 33, front-rear impact fractures to 9 and 20, and multiple fractures to 6 and 1 among the shock and non-shock patients, respectively (p=0.027). Thirty-nine (39) cases in non-shock injuries were conservatively managed while 18 cases in shock injuries were surgically treated. In the shock group, the liver and the kidney were often damaged, as well. Among the shock patients, the average admission period was $7.5{\pm}8.7days$ in intensive care and $55.1{\pm}47.9days$ in total, which were longer than the corresponding numbers of days for the non-shock patients (p<0.05). No deaths occurred in the non-shock group while 5 deaths (14.2%) occurred in the shock group (p=0.007). Conclusion: The factors affecting hemodynamic instability in patients with pelvic bone fracture are injury mechanism, classification of fracture, and associated injuries.

배경: 본 연구는 심폐바이패스를 사용하지 않는 관상동맥우회술 중 발생한 혈역학적 불안정에 대한 대동맥내 풍선펌프 치료의 유용성을 평가하고자 하였다. 대상 및 방법: 2000년 1월부터 2006년 12월까지 심폐바이패스를 사용하지 않는 관상동맥우회술을 받은 796명의 환자를 대상으로 하였다. 수술중 대동맥내 풍선펌프 삽입이 필요했던 환자들을 I군(n=39), 삽입하지 않았던 환자들을 II군(n=757)으로 분류하였다. 결과: 두 군간에 수술 사망률(2.6%, 1/39 vs. 0.8%, 6/757; p=0.195)과 심방 세동(p=0.691), 뇌졸중(p=0.908), 종격동염(p=0.781) 이환율의 차이는 없었다. 인공호흡기 치료 시간, 중환자실 및 병원 재원 기간은 I군에서 II군보다 길었다 (p<0.05). 다변량 분석에서 수술 중 대동맥내 풍선 펌프 삽입이 수술 사망률을 유의하게 증가시키진 않았다(p=0.549). I군에서 대동맥내 풍선 펌프 치료와 관련하여 수술적 치료가 필요했던 합병증이 3예 있었으나(7.9%), 대동맥내 풍선 펌프 삽입 술기를 변형한 2003년 이후에는 발생하지 않았다. 결론: 심폐바이패스를 사용하지 않는 관상동맥우회술 중 혈역학적 불안정이 발생한 경우 대동맥내 풍선펌프를 이용하여 비교적 적은 합병증으로 관상동맥우회술을 시행할 수 있었다.

We report a case of primary undifferentiated cardiac sarcoma. The tumor originated from the left atrial free wall with multi-organ metastases, e.g., lung, and adrenal gland. The patient gradually grew worse with dyspnea and hemoptysis because of the obstructed left atrial outflow. Surgical resection of the left atrial sarcoma was undertaken to save the patient's life, followed by chemotherapy and brain irradiation as adjuvant therapy. The prognosis of cardiac sarcoma with metastases is very poor. However, in patients with hemodynamic instability, surgical intervention could be a therapeutic modality as palliation.

Cephalohematoma with epidural hematoma[EDH] is a known complication of birth trauma and is usually best managed by observation only. However, this complication may jeopardize a neonatal life because of cranial compromise and hemodynamic instability. It should also be recognized that surgical intervention confers undoubted benefits on patients in some cases. We report a case of massive EDH with cephalohematoma and linear skull fracture, successfully treated with a craniotomy and evacuation of the hematoma.

Purpose: There is little controversy that a classic indication such as hemodynamic instability or any sign of peritoneal irritation requires an immediate laparotomy in the management of abdominal stab wounds. However, omental herniation or bowel evisceration as an indication for an immediate laparotomy is controversial. The purpose of this study was to evaluate the significance of these factors as indications for an immediate laparotomy. Methods: The medical records of 98 consecutive abdominal stab wounds patients admitted to the Emergency Center of Masan Samsung Hospital from January 2000 to December 2006 were carefully examined retrospectively. Using multivariate logistic regression analysis, thirty-nine factors, including the classic indication and intraabdominal organ evisceration, were evaluated and were found to be associated with a need for a laparotomy. Also, the classic indication was compared with a new indication consisting of components of the classic indication and intra-abdominal organ evisceration by constructing a contingency table according to the need for a laparotomy. Results: Multivariate logistic regression analysis revealed any sign of peritoneal irritation, base deficit, and age to be significant factors associated with the need for a laparotomy (p<0.05). The sensitivity, specificity, and accuracy rates of the classic indication were 98.6%, 72.0%, and 91.8%, respectively, and those of the new indication were 93.2%, 84.0%, and 90.8%, respectively. The differences in those rates between the above two indications were not significant. Conclusion: Intra-abdominal organ evisceration was not a significant factor for an immediate laparotomy. Moreover, the new indication including intra-abdominal organ evisceration was not superior to the classic indication. Therefore, in the management of abdominal stab wounds, the authors suggest that an immediate laparotomy should be performed on patients with hemodynamic instability or with any sign of peritoneal irritation.

Outcomes of ventricular septal rupture (VSR) as a complication of acute myocardial infarction are extremely poor, with an in-hospital mortality rate of 45% in surgically treated patients and 90% in patients managed with medication. Delaying surgery for VSR is a strategy for reducing mortality. However, hemodynamic instability is the main problem with this strategy. In the present case, venoarterial extracorporeal membrane oxygenation (ECMO) was used to provide stable hemodynamic support before the delayed surgery. Awake ECMO was also used to avoiding the complications of sedatives and mechanical ventilation. Here, we describe a successful operation using awake ECMO as a bridge to surgery.
