Purpose: Computed tomography (CT) is an accurate test for evaluating hemodynamically stable patients with blunt abdominal trauma. Until now, there have been few studies concentrating on the diagnostic and prognostic significance of the intravenous contrast extravasation (CE) site. We investigated the site of CE on abdominopelvic CT (APCT) and its effect on treating trauma patients and predicting the clinical outcome. Methods: The 50 patients admitted to our emergency department with blunt abdominal trauma showing CE on APCT from January 2004 to September 2006 were included in this study. Patients were prospectively collected, and medical records were reviewed and analyzed. The patients'clinical and lab findings, Focused Assessment with Sonography for Trauma (FAST) findings, CT findings were analyzed. CE sites were classified as intraperitoneal, retroperitoneal, and pelvic cavity and were correlated with post-treatment complications, mortality, and morbidity. Results: Of the 50 patients (mean age : $45{\pm}18years$, 29 males, 21 females) included in our study, 33 patients died (66%). There was no correlation between CE site and ICU or total hospitalization duration (p=0.553, p=0.523). During the first 24 hours of resuscitation, the pelvic cavity group required a mean of 20 units more of packed red blood cell (pRBC) transfusion compared to other groups (p=0.003). In the intraperitoneal group, more patients received operative invasive intervention - either laparotomy or embolization (p=0.025). The intraperitoneal group had the highest mortality, with 13 deaths (11/33, 39%), and the highest early mortality rate (10/13, 76%) in the first 24 hours (p=0.001). Conclusion: Intraperitoneal CE on the CT scan in cases of blunt abdominal trauma is regarded as an indication of a need for invasive intervention (either angiography or laparotomy) and of a higher mortality rate in the first 24 hours. A pelvic cavity CE rquires more aggressive transfusion with pRBC. However, the CT findings themselves showed no significant correlation with overall mortality, morbidity, or hospitalization.

Objective: This study examined whether emergency department (ED) crowding influences the timing of the initial assessment and treatment in severe trauma patients, as well as their mortality rates. Methods: This retrospective, observational study was conducted between January 2015 and October 2016, and included adult severe trauma patients who presented to the ED. The emergency department occupancy rate (EDOR) was used to measure ED crowding. The patients were divided into four groups using the EDOR quartile. The timeliness of the initial assessment and treatment in the four groups as well as the mortality rates were compared. Results: This study investigated 307 patients. The timing of the first computed tomography (CT) and laboratory test order, CT and laboratory test result acquisition, first transfusion, and patient transfer from the ED to the operating room were similar in the four groups. Multivariable logistic regression analysis did not show a significant difference in mortality between the groups. Conclusion: ED crowding was not associated with delays in the initial assessment and treatment of severe trauma patients, or in their mortality rates.

연구배경 : 체외 순환으로 인한 지혈 기전의 심각한 손상은 술후 과다 출혈을 일으켜 환자의 생명을 위협하고, 대량 수혈에 따른 부작용과 재수술의 우려마저 증가시킬 수 있다. 특히, 심장 수술동안 섬유소 용해계의 활성화와 혈소판의 숫적, 기능적 변화가 술후 상당 시간동안 출혈의 원인이 된다고 보고하고 있다 대상 및 방법 : 본 연구는 체외 순환 동안 및 그 후에 있어, 체외 순환에 의한 섬유소 용해계의 활성화를 포함한 다양한 혈액학적 변화를 조사하고, 이러한 변화들이 술후 비외과적 출혈의 정도와 어떤 상관성이 있는가를 규명하기위해 체외 순환을 실시할 성인 환자 20명을 대상으로 전향적으로 계획되었다. 혈소판 수, 섬유소원 및 plasminogen 농도, FDP, D-dimer, BT, aPTT, PT와 같은 혈액학적 변수의 측정을 위해 수술동안 또는 술후 시기에 혈액을 연속적으로 채취하였다. 출혈량은 흉부 삽관을 통한 배출량을 술후 3, 6, 12, 24, 48시간의 양과 총혈액량을 각각 측정하였다. 결과 : 연구 결과를 요약하면 다음과 같다:혈소판 수는 체외 순환으로 인해 급격히 감소되었다 (p<0.01). 총 체외 순환 시간이 길수록 혈소판 수의 감소률은 더 높았으며 (r=0.55, p=0.01) 술후 7일이 되어서야 비로소 술전치에 근접하였다. 체외 순환동안 FDP와 D-dimer의 농도가 의미있게 증가하였고 (p<0.0001), 섬유소원 및 plasminogen 농도 둘 다 서로간에 상관성을 보이면서 감소하였다 (r=0.57, p<0.01). 술후 2hr-BT, 2hr-PT, 2hr-aPTT 모두 술전치에 비해 유의하게 연장되었다(각각 p<0.05, p<0.0001, p<0.0001). 술후 총 출혈량과 환자의 연령, 대동맥 차단 시간, 체외 순환 시간은 각각 양의 상관관계 (positive correlation)가 있었다. 술전 기준치 혈소판 수와 술후 3시간 출혈량, 체외 순환 종료시의 혈소판 수와 술후 3시간, 6시간 및 총 출혈량 그리고 술후 1일의 혈소판 수와 48시간 출혈량 사이에는 각각 음의 상관관계 (negative correlation)가 있었다. 술후 2hr-aPTT는 술후 6시간 및 48시간대의 출혈량에 상관성이 있었고 (r=0.53, p=0.02) 술후 2hr-PT는 48시간 출혈량과 각각 양의 상관성이 있었으나 (r=0.43, p=0.05). 이 두가지 변수와 총 출혈량 간에는 상관성이 없었고, 술후 2hr-BT와 술후 출혈량 사이에도 유의한 상관성을 발견하지 못하였다. 결론 : 이상의 관찰 결과들은 체외 순환이 섬유소 용해계의 활성화와 혈소판 수의 심한 감소를 포함한 다양한 혈액학적 변화를 유도하고 환자의 연령, 혈소판 수, 대동맥 차단 시간, 체외 순환 시간, 술후 PT 및 aPTT와 같은 다인적 상황들이 술후 출혈에 영향을 미친다는 점들을 시사하고 있다. 본 연구 결과들은 체외 순환에 따른 지혈적 손상에 관한 이해와 술후 출혈을 감소시키기 위한 기초 자료로 활용 가능하리라 사료된다.

본 증례에서는 한방치료를 받은 두 명의 골수이형성증후군 환자를 통하여 골수이형성증후군에 대한 한방치료의 효과를 보여주고자 하였다. 골수이형성증후군은 골수의 증식과 구성 세포들의 이형성, 비효율적인 조혈을 특징으로 하는 골수의 악성 종양이다. 현재까지 골수이형성증후군에 대한 완벽한 치료법은 없으며 골수이형성증후군의 증상을 경감시키거나 급성 골수성 백혈병으로의 진행을 막는 목적으로 치료가 이뤄지고 있다. 첫 번째 환자는 1차성 골수이형성증후군 환자로 2011년 1월부터 2016년 현재까지 꾸준히 침 치료 및 한약치료를 받고 있다. 두 번째 환자는 난소암 치료를 위한 항암화학요법의 부작용으로 생긴 2차성 골수이형성증후군 환자로 2010년 10월부터 4년간 꾸준한 한약 복용 및 3번의 입원치료를 받은 환자이다. 침 치료, 한약 치료와 함께 환자들의 상태를 평가하기 위해 정기적인 혈액검사가 이루어졌다. 골수이형성증후군 진단 후 두 달에 한 번씩 수혈을 받으며 수혈 의존 경향을 보이던 첫 번째 환자는 한방치료 후 단 두 번의 수혈밖에 받지 않았고 급성골수성백혈병으로 진행하지도 않았으며 건강한 몸 상태를 유지하고 있다. 두 번째 환자 역시 꾸준한 한방치료를 통해 비교적 좋은 삶의 질을 유지하며 기본 체력 또한 많이 상승되면서 골수 이식을 받을 정도까지 몸 상태가 개선되었다. 본 증례보고는 마땅한 치료법이 없는 골수이형성증후군 환자들에게 한방 치료가 특별한 부작용 없이 환자들이 호소하는 증상을 개선하고 기본적인 체력 증진에 도움이 되며 급성 골수성 백혈병으로의 진행을 예방하는 동시에 기존의 보존적 치료법의 효과를 극대화 시키는 효과가 있음을 보여주는 증례라고 하겠다.

Objective: To investigate the effect of intraoperative glucose fluctuation and postoperative interlukin-6 (IL-6), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), C-reactive protein (CRP) levels on the short-term prognosis of patients with intracranial supratentorial neoplasms. Materials and Methods: Eighty-six patients undergoing intracranial excision were selected in The Second Hospital of Jilin University. According to the condition of glucose fluctuation, the patients were divided into group A (glucose fluctuation <2.2 mmol/L, n=57) and group B (glucose fluctuation ${\geq}2.2mmol/L$, n=29). Glucose was assessed by drawing 2 mL blood from internal jugular vein in two groups in the following time points, namely fasting blood glucose 1 d before operation ($T_0$), 5 min after anesthesia induction ($T_1$), intraoperative peak glucose ($T_2$), intraoperative lowest glucose ($T_3$), 5 min after closing the skull ($T_4$), immediately after returning to intensive care unit (ICU) ($T_5$) and 2 h after returning to ICU ($T_6$). 1 d before operation and 1, 3 and 6 d after operation, serum IL-6 and TNF-${\alpha}$ levels were detected with enzyme-linked immunosorbent assay (ELISA), and CRP level with immunoturbidimetry. Additionally, postoperative adverse reactions were monitored. Results: There was no statistical significance between two groups regarding the operation time, anesthesia time, amount of intraoperative bleeding and blood transfusion (P>0.05). The glucose levels in both groups at $T_1{\sim}T_6$ went up conspicuously compared with that at $T_0$ (P<0.01), and those in group B at $T_2$, $T_4$, $T_5$ and $T_6$ were significantly higher than in group A (P<0.01). Serum IL-6, TNF-${\alpha}$ and CRP levels in both groups 1, 3 and 6 d after operation increased markedly compared with 1 d before operation (P<0.01), but the increased range in group A was notably lower than in group B (P<0.05 or P<0.01). Postoperative incidences of hypoglycemia, hyperglycemia and myocardial ischemia in group A were significantly lower than in group B (P<0.05), and respiratory support time obviously shorter than in group B (P<0.01). Conclusions: The glucose fluctuation of patients undergoing intracranial excision is related to postoperative IL-6, TNF-${\alpha}$ and CRP levels and those with small range of glucose fluctuation have better prognosis.

말라리아는 세계적으로 매년 1억 이상의 환자를 발생시키며 그 중 약 100만 명씩을 사망케 하고 있는 무서운 원충 질환으로 잘 알려져 있다. 우리 나라에는 과거에 삼일열 말라리아 (tefilnmuwia)의 유행이 있었으나 1970년대 말 이후부터는 토착적 환자 발생 보고가 없어 소멸된 것으로 알려져 왔다. 그러나 최근 저자 등은 해외 여행 경력이 없는 환자 1명에서 삼일열원충 (Plasmodium vivax) 감염을 확일하였기에 보고하고자 한다. 환자는 23세 남자인 국군 병사로서 1993년 7월 중순부터 18일 동안 격일로 매회 4-8시간씩 계속되는 발열과 오한을 주소로 내원하였다. 환자는 경남 창원시에 거주하였고 1992년 6월 군에 입대한 후에는 경기도 파주군의 한 야전군 부대에 근무해 왔으나 외국에 나간 일은 전혀 없다고 하였다. 과거력상 수혈을 받거나 정맥주사를 맞은 일도 없다고 하였다. 환자의 말초혈액 도말 표본에서는 삼일열원충의 ring form, trophozoite, schizont 및 gametocyte가 검출되었고, 약간의 적혈구 감소와 혈소판 감소가 관찰되었다 확진 후 hydroxychloroquine과 primaquine을 투여하여 치료하였고, 추적 혈액 도말검사에서는 말라리아 원충을 발견할 수 없었다. 이 증례가 우리 나라 토착적 말라리아의 재유행에 의한 것인지, 도입성 (introduced) 말라리아의 국내 정착에 의한 2차 감염 환자인지는 판단하기가 쉽지 않으나. 어쨌든 말라리아가 다시 유행할 가능성 에 대해서는 커다란 관심을 기울여 야 할 것으로 생각되었다.

Objective We compared the predictive value of the National Early Warning Score+Lactate (NEWS+L) score with those of other parameters such as the pre-endoscopic Rockall score (PERS), Glasgow-Blatchford score (GBS), and albumin, international normalized ratio, altered mental status, systolic blood pressure, age older than 65 years score (AIMS65) among patients with upper gastrointestinal bleeding (UGIB). Methods We conducted a retrospective study of patients with UGIB during 2 consecutive years. The primary outcome was the composite of in-hospital death, intensive care unit admission, and the need for ${\geq}5$ packs of red blood cell transfusion within 24 hours. Results Among 530 included patients, the composite outcome occurred in 59 patients (19 inhospital deaths, 13 intensive care unit admissions, and 40 transfusions of ${\geq}5$ packs of red blood cells within 24 hours). The area under the receiver operating characteristic curve of the NEWS+L score for the composite outcome was 0.76 (95% confidence interval, 0.70 to 0.82), which demonstrated a significant difference compared to PERS (0.66, 0.59-0.73, P=0.004), but not to GBS (0.70, 0.64-0.77, P=0.141) and AIMS65 (0.76, 0.70-0.83, P=0.999). The sensitivities of NEWS+L scores of 3 (n=34, 6.4%), 4 (n=92, 17.4%), and 5 (n=171, 32.3%) were 100%, 98.3%, and 96.6%, respectively, while the sensitivity of an AIMS65 score of 0 (n=159, 30.0%) was 91.5%. Conclusion The NEWS+L score showed better discriminative performance than the PERS and comparable discriminative performance to the GBS and AIMS65. The NEWS+L score may be used to identify low-risk patients among patients with UGIB.

Hemodialysis is essential treatment for the chronic renal failure patient's long-term cure and for the patient management before and after kidney transplantation. It sustains the endstage renal failure patient's life which didn't get well despite strict regimen and furthermore it becomes an essential treatment to maintain civil life. Bursing implementation in hemodialysis may affect the significant effect on patient's life. The purpose of this study was to obtain the basic data to solve the hypotension problem encountable to patient and the blood loss problem affecting hemodialysis patient'a anemic states by incomplete rinsing of blood in coil through all process of hemodialysis. The subjects for this study were 44 patients treated hemodialysis 691 times in the hemodialysis unit, The .data was collected at Gang Nam 51. Mary's Hospital from January 1, 1981 to April 30, 1981 by using the direct observation method and the clinical laboratory test for laboratory data and body weight and was analysed by the use of analysis of Chi-square, t-test and anlysis of varience. The results obtained an follows; A. On clinical laboratory data and other data by dialysis Procedure. The average initial body weight was 2.37 ± 0.97kg, and average body weight after every dialysis was 2.33 ± 0.9kg. The subject's average hemoglobin was 7.05±1.93gm/dl and average hematocrit was 20.84± 3.82%. Average initial blood pressure was 174.03±23,75mmHg and after dialysis was 158.45±25.08mmHg. The subject's average blood ion due to blood sample for laboratory data was 32.78±13.49cc/ month. The subject's average blood replacement for blood complementation was 1.31 ±0.88 pint/ month for every patient. B. On the hypotensive state and the coping approaches occurrence rate of hypotension was 28.08%. It was 194 cases among 691 times. 1. In degrees of initial blood pressure, the most 36.6% was in the group of 150-179mmHg, and in degrees of hypotension during dialysis, the most 28.9% in the group of 40-50mmHg, especially if the initial blood pressure was under 180mmHg, 59.8% clinical symptoms appeared in the group of“above 20mmHg of hypotension”. If initial blood pressure was above 180mmHg, 34.2% of clinical symptoms were appeared in the group of“above 40mmHg of hypotension”. These tendencies showed the higher initial blood pressure and the stronger degree of hypotension, these results showed statistically singificant differences. (P=0.0000) 2. Of the occuring times of hypotension,“after 3 hrs”were 29.4%, the longer the dialyzing procedure, the stronger degree of hypotension ann these showed statistically significant differences. (P=0.0142). 3. Of the dispersion of symptoms observed, sweat and flush were 43.3%, and Yawning, and dizziness 37.6%. These were the important symptoms implying hypotension during hemodialysis accordingly. Strages of procedures in coping with hypotension were as follows ; 45.9% were recovered by reducing the blood flow rate from 200cc/min to 1 00cc/min, and by reducing venous pressure to 0-30mmHg. 33.51% were recovered by controling (adjusting) blood flow rate and by infusion of 300cc of 0,9% Normal saline. 4.1% were recovered by infusion of over 300cc of 0.9% normal saline. 3.6% by substituting Nor-epinephiine, 5.7% by substituting blood transfusion, and 7,2% by substituting Albumin were recovered. And the stronger the degree of symptoms observed in hypotention, the more the treatments required for recovery and these showed statistically significant differences (P=0.0000). C. On the effects of the changes of blood pressure and osmolality by albumin and hemofiltration. 1. Changes of blood pressure in the group which didn't required treatment in hypotension and the group required treatment, were averaged 21.5mmHg and 44.82mmHg. So the difference in the latter was bigger than the former and these showed statistically significant difference (P=0.002). On the changes of osmolality, average mean were 12.65mOsm, and 17.57mOsm. So the difference was bigger in the latter than in the former but these not showed statistically significance (P=0.323). 2. Changes of blood pressure in the group infused albumin and in the group didn't required treatment in hypotension, were averaged 30mmHg and 21.5mmHg. So there was no significant differences and it showed no statistical significance (P=0.503). Changes of osmolality were averaged 5.63mOsm and 12.65mOsm. So the difference was smaller in the former but these was no stitistical significance (P=0.287). Changes of blood pressure in the group infused Albumin and in the group required treatment in hypotension were averaged 30mmHg and 44.82mmHg. So the difference was smaller in the former but there is no significant difference (P=0.061). Changes of osmolality were averaged 8.63mOsm, and 17.59mOsm. So the difference were smaller in the former but these not showed statistically significance (P=0.093). 3. Changes of blood pressure in the group iutplemented hemofiltration and in the Uoup didn't required treatment in hypotension were averaged 22mmHg and 21.5mmHg. So there was no significant differences and also these showed no statistical significance (P=0.320). Changes of osmolality were averaged 0.4mOsm and 12.65mOsm. So the difference was smaller in the former but these not showed statistical significance（P=0.199). Changes of blood pressure in the group implemented hemofiltration and in the group required treatment in hypotension were averaged 22mmHg and 44.82mmHg. So the difference was smatter in the former and these showed statistically significant differences (P=0.035). Changes of osmolality were averaged 0.4mOsm and 17.59mOsm. So the difference was smaller in the former but these not showed statistical significance (P=0.086). D. On the changes of body weight, and blood pressure, between the group of hemofiltration and hemodialysis. 1, Changes of body weight in the group implemented hemofiltration and hemodialysis were averaged 3.340 and 3.320. So there was no significant differences and these showed no statistically significant difference, (P=0.185) but standard deviation of body weight averaged in comparison with standard difference of body weight was statistically significant difference (P=0.0000). Change of blood Pressure in the group implemented hemofiltration and hemodialysis were averaged 17.81mmHg and 19.47mmHg. So there was no significant differences and these showed no statistically significant difference (P=0.119), But in comparison with standard deviation about difference of blood pressure was statistically significant difference. (P=0.0000). E. On the blood infusion method in coil after hemodialysis and residual blood losing method in coil. 1, On comparing and analysing Hct of residual blood in coil by factors influencing blood infusion method. Infusion method of saline 200cc reduced residual blood in coil after the quantitative comparison of Saline Occ, 50cc, 100cc, 200cc and the differences showed statistical significance (p < 0.001). Shaking Coil method reduced residual blood in Coil in comparison of Shaking Coil method and Non-Shaking Coil method this showed statistically significant difference (P < 0.05). Adjusting pressure in Coil at OmmHg method reduced residual blood in Coil in comparison of adjusting pressure in Coil at OmmHg and 200mmHg, and this showed statistically significant difference (P < 0.001). 2. Comparing blood infusion method divided into 10 methods in Coil with every factor respectively, there was seldom difference in group of choosing Saline 100cc infusion between Coil at OmmHg. The measured quantity of blood loss was averaged 13.49cc. Shaking Coil method in case of choosing saline 50cc infusion while adjusting pressure in coil at OmmHg was the most effective to reduce residual blood. The measured quantity of blood loss was averaged 15.18cc.

배경: 심혈관 수술 시 일반적으로 사용하는 저체온 체외순환이 세포의 저체온 손상, 말초혈관계의 비정상적 반응 및 수술 후 높은 출혈 경향을 일으키는데 비해 정상체온 체외순환은 이러한 저체온 체외순환의 유해한 효과들을 예방하고 심장의 빠른 회복을 가져다준다고 한다. 저자들의 연구는 염증 및 혈액학적 반응에 대한 저체온 체외순환과 정상체온 체외순환의 영향을 비교하기 위해 전향적으로 실시되었다. 대상 및 방법: 심장수술이 계획된 34명의 성인 환자들을 연구목적에 따라 무작위로 저체온 체외순환군(비인두 온도 26～28$^{\circ}C$, n=17, 저체온군)과 정상체온 체외순환군(비인두 온도&35.5$^{\circ}C$, n=17, 정상체온군)으로 나누었다. 심근보호는 양 군 모두 비혈액성 냉각심정지법을 적용하였다. 환자들로부터 체외순환 시작 전(Pre-CPB), 체외순환 실시 10분(CPB-10), 체외순환 종료 후(CPB-OFF)에 요골동맥으로부터 혈액을 채취하여 총 백혈구 수, 혈소판 수, interleukin-6 (IL-6)농도의 변화율(백분율로 표시), D-dimer 농도, protein C 활성도 및 Protein S 활성도를 측정하였고 수술 후 24시간 출혈량, 혈액제제 사용량도 조사하여 양 군 간에 비교 평가하였다. 결과: Pre-CPB에 비해 CPB-OFF의 경우 정상체온군의 총 백혈구 수(10,032$\pm$65/mm$^3$) 및 IL-6 증가율(353$\pm$7.0%)이 저체온군의 총 백혈구 수(7,254$\pm$$48/mm^3$) 및 IL-6 증가율(298$\pm$7.3%)보다 유의하게 높았다(p=0.02 및 p=0.03). 그러나 정상체온군의 protein C activity (32$\pm$3.8%) 및 protein S activity (35$\pm$4.1%)는 저체온군의 protein C activity (45$\pm$4.3%) 및 Protein S activity (51$\pm$3.8%)보다 유의하게 낮았다(p=0.04 및 p=0.009). 체외 순환 중 혈소판 수와 D-dimer농도의 변화는 양 군 간에 유의한 차이가 없었다. 정상체온군의 수술 후 24시간 출혈량(850$\pm$23.2 mL) 및 수혈을 위한 농축적혈구(1,402$\pm$20.5 mL), 신선냉동혈장(970$\pm$20.8 mL), 농축 혈소판(252$\pm$6.4 rnL) 사용량은 저체온군의 수술 후 24시간 출혈량(530$\pm$21.5 mL) 및 수혈을 위한 농축적혈구(696$\pm$15.7 mL), 신선냉동혈장(603$\pm$18.2 mL), 농축혈소판(50$\pm$0.0 mL) 사용량보다 유의하게 더 높았다(p=0.04 및 p=0.01, p=0.04, p=0.01). 결론: 정상체온 체외순환은 저체온 체외순환에 비해 더 높은 염증반응, 수술 후 더 많은 출혈 및 혈액제제 사용량의 증가를 유발하므로, 저자들은 심장수술시 정상체온 순환법을 일상적으로 사용하기 위해서는 더 많은 연구가 필요할 것으로 생각한다.

목적: 암환자에게 있어 중심 정맥관 삽입은 항암치료나 수혈, 비경구 영양공급 목적으로 흔히 시행된다. 중심정맥관 삽입으로 인해 발생하는 합병증으로는 감염, 혈전, 물리적 합병증이 있는데, 이 연구는 합병증의 빈도와 관련 인자들을 규명하기 위해 계획되었다. 방법: 2001년 3월부터 2006년 8월까지 중심 정맥관을 삽입한 고형암과 혈액암 환자를 대상으로 경과기록 분석을 통한 후향적 연구를 시행하였다. 감염, 혈전, 물리적 합병증 각각의 빈도를 조사하였고, 감염과 혈전의 발생에 영향을 미치는 여러 인자들과 그 연관성을 분석하기 위해 교차 분석을 사용하였다. 또한, 삽입관 수명에 영향을 미치는 인자들을 알기 위해 단변량 분석에는 log-rank test를 이용한 Kaplan-Meier 방법과 다변량 분석에는 Cox regression analysis 를 사용하였다. 결과: 310명의 암환자들에게 310개의 중심 정맥관 삽입이 시술되었고, 남자 157명, 여자 153명이었고, 혈액암 환자가 132명, 고형암 환자 178명이었으며, 평균 연령은 52세였다(range: 15~82). 60예(19%)의 환자에서 합병증이 나타났으며, 혈전을 가진 환자에서 감염이 더 빈번하게 일어났고(P=0.003), 암이나 삽입관의 종류, 수혈 및 비경구 영양 시행 여부와 합병증 발생과는 큰 연관성이 없었다. 삽입관의 평균수명은 99일(range: 2~1,330)이었는데 삽입관의 수명은 터널식 삽입관(P=0.000)을 가진 경우에, 그리고 중심정맥관을 통해 수혈을 하지 않은 경우(P=0.030) 더 연장되었다. 결론: 중심 정맥관 삽입의 주요 합병증은 혈전과 감염이었다. 터널식 정맥관은 장기적인 사용에 효과적인 방법이며, 특히 중심정맥관을 통해 수혈을 받지 않는 경우에 그러하다. 중심 정맥관 장기 사용을 위해 혈전과 감염의 예방 및 치료에 대한 연구가 더욱 이루어져야할 것으로 여겨진다.
