쇼크(shock)란 조직에 필요한 산소 요구량과 공급 간의 불균형에 의해 유발되는 임상증후군을 말한다. 환자의 치료효과와 생존율 향상을 위해서 쇼크의 조기 진단은 매우 중요하다. 그러나 현재 쇼크 진단에 사용되는 맥박, 혈압 등 생체 징후의 경우 출혈 정도를 제대로 반영하지 못하여 환자에 대한 처치가 늦어질 수 있다. 따라서 쇼크의 조기 진단을 위한 많은 연구들이 진행되어 왔으며, 조직의 저산소증, 대사성 산증을 반영해주는 지표인 젖산 농도와 관류 측정의 유용성이 입증된 바 있다. 본 연구에서는 흰쥐를 대상으로 정량적 출혈을 유도한 후, 젖산 농도 측정과 laser Doppler flowmeter를 통해 관류를 측정하였으며, 지혈 후 젖산 농도/관류의 비(ratio)를 생존 예측을 위한 새로운 지표로써 제안하였다. 새로 제안된 지표를 통한 생존예측을 ROC 커브 방법에 적용한 결과, 민감도 90.0%, 특이도 96.7%, 정확도 94.0%를 보였으며, 생존군과 사망군 간 새로운 지표의 유의한 차이도 가장 조기에 보여주었다. 향후 임상 적용 연구를 통해 새롭게 제안한 지표의 임상 적용이 가능하다면, 쇼크 환자를 조기 진단하고 치료효과를 높일 수 있을 것으로 생각된다.

Objectives: We aimed to investigate the acute effects of heat stress on body temperature and blood pressure of elderly individuals living in poor housing conditions. Methods: Repeated measurements of the indoor temperature, relative humidity, body temperature, and blood pressure were conducted for 20 elderly individuals living in low-cost dosshouses in Seoul during hot summer days in 2010. Changes in the body temperature, systolic blood pressure (SBP) and diastolic blood pressure (DBP) according to variations in the indoor and outdoor temperature and humidity were analyzed using a repeated-measures ANOVA controlling for age, sex, alcohol, and smoking. Results: Average indoor and outdoor temperatures were $31.47^{\circ}C$ (standard deviation [SD], $0.97^{\circ}C$) and $28.15^{\circ}C$ (SD, $2.03^{\circ}C$), respectively. Body temperature increased by $0.21^{\circ}C$ (95% confidence interval [CI], 0.16 to $0.26^{\circ}C$) and $0.07^{\circ}C$ (95% CI, 0.04 to $0.10^{\circ}C$) with an increase in the indoor and outdoor temperature of $1^{\circ}C$. DBP decreased by 2.05 mmHg (95% CI, 0.05 to 4.05 mmHg), showing a statistical significance, as the indoor temperature increased by $1^{\circ}C$, while it increased by 0.20 mmHg (95% CI, -0.83 to 1.22 mmHg) as outdoor temperature increased by $1^{\circ}C$. SBP decreased by 1.75 mmHg (95% CI, -1.11 to 4.61 mmHg) and 0.35 mmHg (95% CI, -1.04 to 1.73 mmHg), as the indoor and outdoor temperature increased by $1^{\circ}C$, respectively. The effects of relative humidity on SBP and DBP were not statistically significant for both indoor and outdoor. Conclusions: The poor and elderly are directly exposed to heat waves, while their vital signs respond sensitively to increase in temperature. Careful adaptation strategies to climate change considering socioeconomic status are therefore necessary.

배경 : 본 연구의 목적은 흉골골절에서 심혈관계 동반 손상의 예측인자를 알아내고 응급 심장 초음파검사의 적응증을 제시하고자 하였다. 대상 및 방법 : 1994년 3월부터 5년간 이화여자대학교 부속 목동병원 응급실을 통해 입원한 흉골골절로 입원한 40명의 환자들을 대상으로 후향적 분석을 시행하였다. 예측인자로서는 1) 안전띠 착용의 유무, 2) 동반 손상의 유무, 3) 심혈관계 질환의 병력 유무, 4) 내원시 환자의 RTS(Revised Trauma Score) 4가지를 대상으로 분석하였다. 또한 심혈관계 손상의 동반 유무를 파악하기 위하여 일반적으로 사용하는 심전도와 흉부 단순 촬영 및 심근 효소의 분획을 조사하였으며, 그 결과에서, 흉골골절에서 응급 심장 초음파 검사의 적응증을 추론하였다. 결과 : 흉골골절에서 심혈관계 손상의 동반 유무를 나타내는데 통계적으로 의미가 있다고 나온 인자로는 심혈관계 과거 병력이 있는 경우와 입원시 RTS의 이상을 들 수 있다. 응급 심장 초음파검사의 시행은 예측인자들과 심전도와 흉부 단순 촬영 및 심근 효소의 분획 같은 일반적으로 사용하는 검사 결과에 따라 시행하였다. 흉골골절 환자에서 응급 심장 초음파검사의 적응으로 1) 의미 있는 예측 인자의 변화가 없더라도 두 개 이상의 검사에서 이상소견을 보이던가, 2) 예측인자의 의미있는 변화가 하나 이상 나오는 경우를 들 수 있다. 결론 : 흉골골절 환자에서 심혈관계의 과거 병력과 초기활력 징후가 심혈관 동반 손상 유무를 중요하게 나타날 수 있으며, 필요한 경우, 응급 심장 초음파 검사를 시행하여 조기에 확진을 내리는 것이 중요하다고 생각한다.

Background: A peripheral extracorporeal membrane oxygenator (p-ECMO) has been developed to support patients who are dying due to a serious cardiopulmonary condition. This analysis was planned to define the clinical situation in which the patient benefits most from a p-ECMO. Material and Methods: Between June 2007 and Aug 2009, a total of 41 adult patients used the p-ECMO. There were 23 males and 18 females (mean age $54.4{\pm}15.1$ years). All patients had very unstable vital signs with hypoxia and complex cardiac problems. We divided the patients into 4 groups. In the first group, a p-ECMO was used as a bridge to cardiac operation. In the second group, patients did not have the opportunity to undergo any cardiac procedures; nevertheless, they were treated with a p-ECMO. In the third group, patients mostly had difficulty in weaning from CPB (cardiopulmonary bypass) after cardiac operation. The fourth group suffered from many complications, such as pneumonia, bleeding, infections, and LV dysfunction with underlying cardiac problems. All cannulations were performed by the Seldinger technique or cutting down the femoral vessel. A long venous cannula of $DLP^{(R)}$ (Medtronic Inc, Minneapolis, MN) or $RMI^{(R)}$ (Edwards Lifesciences LLC, Irvine, CA) was used together with a 17~21 Fr arterial cannula and a 21 Fr venous cannula. As a bypass pump, a Capiox emergency bypass system ($EBS^{(R)}$; Terumo, Tokyo, Japan) was used. We attempted to maintain a flow rate of $2.4{\sim}3.0\;L/min/m^2$ and an activated clotting time (ACT) of around 180 seconds. Results: Nine patients survived by the use of the p-ECMO. Ten patients were weaned from a p-ECMO but they did not survive, and the remainder had no chance to be weaned from the p-ECMO. The best clinical situation to apply the p-ECMO was to use it as a bridge to cardiac operation and for weaning from CPB after cardiac operation. Conclusion: Various clinical results were derived by p-ECMO according to the clinical situation. For the best results, early adoption of the p-ECMO for anatomical correction appears important.

Purpose: Hemorrhagic shock is the leading cause of death in patients with pelvic bone fractures. The majority of blood loss is due to injured pelvic arteries and retroperitoneal veins and to bleeding from the fracture site itself. Pelvic angiography and embolization of injured vessels is an effective way to control continuous bleeding. However, identifying the bleeding focus in hemodynamically unstable patients before diagnostic intervention is difficult. The purpose of this study was to determine the correlation between fracture patterns in hemodynamically unstable patients with pelvic fractures and later pelvic angiography findings. Methods: We performed a retrospective study of 21 hemodynamically unstable patients with pelvic fractures admitted to our emergency department between April 2001 to April 2006. All 21 patients underwent pelvic angiography. Pelvic fractures were assessed according to the Tile's classification and the degree of injury was assessed using the Injury Severity Score (ISS) and Revised Trauma Score (RTS). The hemodynamic status of the patients was defined using vital signs, base excess, and blood lactate. Fracture patterns were compared with hemodynamic status and angiography findings. Results: In the 5year study period, 21 hemodynamically unstable pelvic bone fracture patients were admitted; ten were men (47.6%), and 11 were women (52.4%). The mean age was 41.1 years (range: ${\pm}20.1$). Of the 21 embolization was performed in 6 patient (28.6%): 1 patient of the 5 unstable pelvic bone fracture patients (20%), and 5 patients of 16 the stable pelvic bone fracture patients (31.3%). There were no significant differences between the RTS (p=0.587) and embolization rate (p=0.774) for either the stable patients or the unstable patients. Patients with arterial injury on angiography had a lower RTS compared with patients without arterial injury but there was no significant difference in ISS between the two groups. The angiographic injured sites were five internal femoral arteries and one external femoral artery. Conclusion: The findings in this study suggest that the pelvic fracture pattern in hemodynamically unstable patients with pelvic fractures does not correlate with pelvic angiography findings.

This study compared the effect of injectable combinations of anesthetics on each of the fluorescein angiographic phases in order to determine the most useful anesthetic combination for the procedure. Acepromazineketamine (AK), xylazine-ketamine (XK), diazepam-ketamine (DK) and zolazepam-tiletamine (ZT) group were administered randomly to 8 dogs with a two-week interval between different combination doses. The vital signs including the heart rate and arterial pressure were measured before anesthesia and every five minutes during anesthesia. Serial angiographic images were obtained after injecting a sodium fluorescein dye (25 mg/kg) and the onset time of arterial phase (AP), arteriovenous phase (AVP), early venous phase (EVP) and late venous phases (LVP) were recorded. The onset time of the AP, AVP and EVP were significantly slower in the AK and XK groups than in the DK and ZT groups. The total duration of the AP and AVP in the AK group was significantly longer than those in the ZT group. The heart rates were significantly higher in the DK and ZT groups. The arterial pressure was significantly higher in the AK and XK groups (p<0.05). There were significant differences in each angiographic onset time and duration depending on the changes in the heart rates and arterial pressure. The AK and XK groups showed a long angiographic duration allowing an accurate evaluation. Overall, it is believed that AK and XK are more useful for performing fluorescein retinal angiography than DK and ZT.

배경: 호스피스 암 환자에게 적합한 경과기록지의 부재 또한 적절한 암성 통증 관리의 장애요인으로서 기존의 "문제 지향식 의무기록"의 경과기록지 형식에서 벗어나 호스피스 암 환자를 위한 의무기록지(HOMR)를 개발하게 되었다. 방법 및 결과: 2004년 3월부터 5월 사이 고대 구로병원 호스피스 팀은 20여 차례의 모임을 갖고 호스피스 환자의 초기 평가 이후 경과기록에 사용할 수 있는 의무기록지를 개발하였다. 구성항목의 결정은 pilot study를 통해 수정과정을 거쳤다. HOMR은 A4용지 크기로 작성자를 위한 지침서 1장과 2장의 경과기록지로 구성되었다. 앞면에는 환자의 인적 사항, 현재 문제목록 및 활동 수행 능력 상태, 검사 결과, 1주일 간의 활력 징후 및 I/O, 배변 횟수가, 뒷면에는 통증 부위, 통증의 성격 및 강도, 약물 및 비약물 요법, 진정 정도, 동반 증상, 약물 부작용 등을 한꺼번에 기록할 수 있도록 구성되어 있다. 결론: 호스피스 암 환자를 위한 의무기록지는 짧은 여명과 다양한 신체 증상을 갖고 있으며 증상의 변화가 빠르지만 만성적인 경과를 보이는 호스피스 환자에게 적합하며 그 자체만으로도 교육자료로서의 가치가 높고 환자를 돌보는 데 있어 진료의 질을 평가하거나 심사할 수 있으므로 진료의 질을 높이는 역할도 기대된다.

Objectives This study is aimed to develop a Clinical Practice Guideline (CPG) on acupuncture treatment for the stroke patients with Post-stroke Urinary Incontinence(PSUI). Methods Experts committee, consisting of stroke or methodology specialists, searched Medline, EMBASE, Cochrane Library, China National Knowledge Infrastructure, and 19 Korean medicine journals. The search terms were selected to screen the randomized controlled trials (RCTs) or systematic reviews for the effectiveness of acupuncture on PSUI, compared with placebo or conventional group. Levels of evidence and grades of recommendations were appraised based on Recommendations for Development of Clinical Practice Guideline in Korean Medicine. Results & Conclusions 8 RCT were included to build the CPG. There was a strong evidence to support the effectiveness of acupuncture treatment for PSUI. The moderate evidence was presented that over 3 times a week of the acupuncture should be performed over 4 weeks on the acupoints, such as BL23, CV3, SP6, CV4, CV6, ST28, BL28, BL32, GV20, BL22, GV4 or ST36, for 15-30 minutes. 1-150 Hz frequency is suggested if electro-acupuncture treatments is performed with. It was also suggested that the procedure should begin at the acute stage just after the vital signs of the patients are stabilized. There was a moderate evidence to support safety of acupuncture treatment for PSUI. We recommend acu-points of constitutional acupuncture for Sasangin on the healthy side.

Purpose: The study examined the poisoned patients' characteristics nationwide in Korea by using data from the National Emergency Department Information System (NEDIS). Methods: Among the patients' information sent to NEDIS from January 1, 2013 to December 31, 2015, the included subjects' main diagnosis in ED showed poisoning according to the 7th edition of the Korean Standard Disease Classification (KCD-7). We analyzed the patients' gender, age, initial vital signs, visit time, stay time of staying in ED, results of ED care, main diagnosis in ED, length of hospitalization, and results of hospitalization. Results: A total of 106,779 ED visits were included in the analysis. There were 55,878 males (52.3%), which was more than the number of females. The number of intentional poisoning was 49,805 (59.6%). 75,499 cases (70.8%) were discharged, and 25,858 cases (24.2%) were hospitalized. The numbers of poisoning patients per 1,000 ED visits were 14 in Chungnam and 11.9 in Jeonbuk. The most common cause of poisoning, according to the main diagnosis, was venomous animals. It was the same for hospitalized patients, and pesticide was next. Pesticide was the most common cause of mortality in ED (228 cases, 46.1%) and after hospitalization (584 cases, 54.9%). The incidence of poisoning by age group was frequent for patients in their 30s to 50s, and mortality in ED and post-hospitalization were frequent for patients in their 60s to 80s. Conclusion: This study investigated the characteristics of poisoning patients reported in the past 3 years. Pesticide poisoning had a high mortality rate for patients in ED and in-hospital. For mortality, there was a high proportion of elderly people over 60. Thus, policy and medical measures are needed to reduce this problem. Since it is difficult to identify the poison substance in detail due to nature of this study, it is necessary to build a database and monitoring system for monitoring the causative substance and enacting countermeasures.
