  • Bloodstream infections (BSI) are caused by planktonic microorganisms, sometimes leading to serious infections such as bacteremia and sepsis. BSI occurs more frequently to the patients wearing the central venous catheter (CVC). The ciprofloxacin-incorporated CVC (CFX-CVC) has been reported previously to possess antimicrobial activity. In this study, the antibacterial activity of CFX-CVC and its mechanism against planktonic BSI cells were explored by using the shake flask test and by examining the release rate of 260 nm-absorbing substances from the bacterial cells indicative of the membrane damage of the bacterial cells. CFX-CVC reduced more than 99.9% of the viable planktonic BSI cells demonstrating its potent antibacterial activity. It provoked bacteriolysis causing leakage of a large amount of 260 nm-absorbing materials from the planktonic bacterial cells like S. aureus and E. coli. These results provide evidence that the antibacterial activity of CFX-CVC came from the inhibition of the stability of the planktonic bacterial cells.

  • 본 연구의 목적은 유치도뇨관, 중심정맥관 및 인공호흡기 감염관리지침에 대한 중환자실 간호사의 지식과 수행도 정도를 파악하고자 하였다. 대상자는 2개의 상급종합병원과 3개의 종합병원의 중환자실에서 근무하는 간호사 175명이다. 자료수집은 2013년 7월 1일부터 7월 31일까지로, 수집된 자료는 SPSS 18.0 통계 프로그램을 사용하여 기술통계, t-test, ANOVA로 분석하였다. 각 지식수준은 유치도뇨 관리관(평균 0.87점), 중심정맥관(0.82점), 인공호흡기(0.82점)순으로 나타났으며, 수행도는 유치도뇨 관리관(평균 4.18점), 인공호흡기(4.04점)중심정맥관(4.07점)순이었다. 지식과 수행도에서는 유치도뇨관(r=.72, p<.00), 중심정맥관(r=.54, p<.001), 및 인공호흡기(r=.30, p<.001) 감염관리간 순 상관관계를 나타냈다. 유치도뇨관 감염관리지침에 대한 지식과 수행도는 성별, 최종학력, 근무경력, 담당환자 수, 병원규모, 세미나 참석 여부에 따라 통계적으로 유의한 차이가 있었다. 중심정맥관 감염관리지침에 대한 지식과 수행도는 최종학력, 근무경력, 담당환자 수, 병원규모, 세미나 참석 여부에 따라 통계적으로 유의한 차이가 있었다. 인공호흡기 감염관리지침에 대한 지식은 근무경력에 따라 통계적으로 유의한 차이가 있었다. 본 연구결과를 기초로 감염관리지침에 대한 지식과 수행을 향상 시킬 수 있는 교육 및 훈련 프로그램이 개발되어야 할 것이다.

  • 투석 환자에서 중심정맥협착은 비교적 흔한 합병증이나, 이로 인한 경정맥역류 및 두개내압 상승은 드물며, 진행성 시력 저하를 보이는 경우는 몇 개의 증례만 보고되고 있다. 저자들은 경정맥역류로 인한 두개내압 상승, 시력 저하 그리고 뇌 MRI에서의 상안정맥 확장에 대해 해면경막 동정맥루로 오인하였던 증례를 보고하고자 한다. 환자는 time-of-flight MR angiography (이하 TOF-MRA)에서 경정맥역류 소견이 있었고, 혈관조영술에서 좌측 완두정맥의 협착이 확인되었다. 중심정맥협착에 대해 풍선혈관성형술을 시행하였고 증상이 호전되어 퇴원하였다. 중심정맥협착에 의한 경정맥역류와 해면경막 동정맥루는 유사한 증상을 보일 수 있으나 치료법이 다르므로, MRI와 TOF-MRA의 면밀한 검토를 토대로 영상의학적으로 감별하는 것이 중요하며, 뇌혈관조영술을 통해 중심정맥협착 유무를 확인하는 것이 필요하다.

  • Background: When managing patients who require repeated venous access, gaining a viable intravenous route has been problematic. To improve the situation, various studies on techniques for venous access have been conducted. The aim of this study is to evaluate the clinical results of complications following totally implanted central venous access port (TICVAP) insertion. Methods: A retrospective analysis was conducted on 163 patients, from December 2008 to March 2013. The occurrence of complications was studied in three separate periods of catheter use: the intraoperative period, postoperative period, and period during the treatment. Results: A total of 165 cases of TICVAP insertions involving 156 patients were included in the final analysis. There were 35 complications (21%) overall. Among these, 31 cases of complications (19%) occurred during the treatment period and the other 4 cases were intraoperative and postoperative complications (2%). There were no statistically significant differences in age and gender of the patients between the two groups to be risk factors (p=0.147, p=0.08). Past history of chemotherapy, initial laboratory findings, and the locations of TICVAP insertion also showed no statistical significance as risk factors (p>0.05). Conclusion: Because the majority of complications occurred after port placement and during treatment, meticulous care and management and appropriate education are necessary when using TICVAPs.

  • Purpose: To determine whether a peripherally inserted central catheter (PICC) meets the goals of a low infection rate and long-term use in trauma patients. Methods: From January 2016 to June 2018, the medical records of patients who underwent central venous catheterization at a level I trauma center were retrospectively reviewed. Data collected included age, sex, injury severity score, site of catheterization, place of catheterization (intensive care unit [ICU], emergency department, or general ward), type of catheter, length of hospital stay during catheterization, types of cultured bacteria, time to development of central line-associated bloodstream infection (CLABSI), and complications. Results: During the study period, 333 central vein catheters (CVC) were inserted with a total of 2,626 catheter-days and 97 PICCs were placed with a total of 2,227 catheter-days. The CLABSI rate was significantly lower in the PICC group when the analysis was limited to patients for whom the catheter was changed for the first time in the ICU after CVC insertion in the ER with similar indication and catheter insertion times (18.6 vs. 10.3/1,000 catheter-days, respectively, p<0.05). The median duration of catheter use was significantly longer in the PICC group than in the CVC group (16 vs. 6 days, respectively, p<0.05). Conclusions: The study results showed that the duration of catheter use was longer and the infection rate were lower in the PICC group than in the CVC group, suggesting that PICC is a safe and reliable alternative to conventional CVC.

  • A 3-year-old girl with a primitive neuroectodermal tumor (PNET) and a 6-yearold girl with acute lymphoid leukemia were referred to us because of problems with their implantable central venous ports (Port-A-Cath$^{(R)}$). On physical examination, the ports were upside-down, so a needle could notbe inserted through the membrane of the port. Right lateral side view of the chest radiogram confirmed port inversion in both cases. At operation, the ports were inverted and the transfixing sutures were totally absorbed. The ports were rotated 180 degrees and anchoring sutures placed.

  • 목 적 : 15세 이하 소아의 중심정맥 도관 관련 감염의 임상적 검토를 통해 원인균을 밝히고 삽입위치, 유치기간, 기저 질환 등에 따른 감염 발생과의 연관성을 조사하고자 하였다. 방 법 : 2003년 1월 1일부터 12월 31일까지 연세의료원에 입원하여 중심정맥 도관을 삽입술을 시행 받은 15세 이하 112명을 대상으로 의무기록의 후향적 검토를 시행하였다. 결 과 : 총 139례의 배양검사가 시행되었으며, 45례(34.2%)에서 중심정맥 도관 감염이 발생했고(Table 1), 53가지 균주가 동정되었다. 발생 균주는 그람 양성인 coagulase negative Staphylococcus가 18례(33.9%)로 가장 많았고 Enterococcus faecium 5례(9.3%), Staphylococcus aureus 4례(7.5%), Enterococcus faecalis 2례(3.8%) 순으로 발생했고, 그람 음성은 Acinetobacter anitratus 3례(5.7%), Pseudomonas aeruginosa 3례(5.7%), Klebsiella pneumonia 2례(3.8%) 순이었으며, 이외 Yeast 4례(7.5%), Candida albicans 3례(5.7%), Acinetobacter species, ${\alpha}$-streptococcus, Candida species, Citrobacter freundii, Diphtheroid 각 1례(1.9%)의 빈도를 보였다. 삽입 부위는 우측 대퇴 정맥이 72례로 가장 많았고, 우측 경정맥 21례, 좌측 대퇴 정맥 20례였다. 중심정맥 도관 삽입 유치기간은 평균 $14.17{\pm}12.00$일이었으며, 감염이 발생하지 않은 군은 $13.19{\pm}9.10$일, 감염이 발생한 군은 $15.98{\pm}15.98$일로 두 그룹 사이에 관련성이 있을 것으로 판단된다(P=0.06). 중심정맥 도관 삽입 환자 중 9명이 사망하였는데 4명에서 중심정맥 도관 감염이 있었으나, 중심정맥 도관 감염과 사망과는 통계적으로 유의한 관계는 없었다(P>0.05). 결 론 : 중심정맥 도관 관련 감염에서 삽입위치, 유치기간에 따른 감염률은 통계적으로 유의한 관계는 보이지 않았다. 또한 흔하게 분리된 coagulase negative Staphylococcus는 피부 상재균으로 임상적인 의미에 대한 추가적인 연구가 필요하며, 향후 중심정맥 도관 관련 감염의 예방 및 치료를 위한 적절한 방법이 개발되어야 할 것으로 생각된다.

  • Background: The use of indwelling central venous access devices (CVADs) in children can result in complications such as infection, occlusion, and dislodgement. Purpose: To evaluate whether reinforcing CVAD care bundles by using a regular direct feedback system could reduce such complications in children. Methods: The intervention in this retrospective interrupted time-series study was initiated in January 2019. The study was divided into the preintervention (October-December 2018), 3-month postintervention (January-March 2019), and 6-month postintervention (April-June 2019) phases. Risk difference and Poisson regression analyses were used to illustrate the effectiveness of the intervention. Results: The hospital-wide central line-related bloodstream infection rate decreased from 10.0/1,000 catheter-days to 4.5/1,000 catheter-days at 3-month postintervention (P=0.39) and to 1.4/1,000 catheter-days at 6-month postintervention (P=0.047). The central line occlusion rate significantly decreased from 30% to 12.8% (P=0.04) and 8.3% (P=0.002) at 3 and 6 months, respectively. Approximately 7% of CVADs became dislodged during the preintervention phase versus 8.5% (P=0.364) and 3.3% (P=0.378) at 3 and 6 months, respectively. Conclusion: Reinforcing CVAD care bundles with direct feedback could significantly decrease CVAD-associated complications in terms of infection at 6-month postintervention, and occlusion at 3- and 6-month postintervention. Thus, reinforcement and regular direct feedback might improve care quality in children with CVADs.
