Purpose: This study was conducted to update the existing nursing practice guideline for intravenous infusion guidelines according to the evidence-based practice guideline in South Korea. Methods: Guideline update process was performed using 22 steps according to the manuals developed by NICE and SIGN. Results: Updated nursing practice guidelines for the intravenous infusion were consisted of 23 domains and 322 recommendations. The number of recommendations in each domain were 4 for general instruction, 12 for vascular access device selection, 20 for site selection, 9 for insertion, 54 for stabilization, 21 for maintaining patency, 4 for blood sampling, 33 for exchange and removal, 28 for add-on device selection, 28, 72 for infusion related complications, 56 for infusion therapies, 7 for education, and 2 for documentation and report. There were 15.9% of A, 30.2% of B, 53.9% of C in terms of grade recommendations. A total of 178 (51.6%) recommendations were newly developed and 24 previous recommendations have been deleted. Conclusion: Updated nursing practice guideline for intravenous infusion was expected to be an evidence-based practice guideline for intravenous infusion in South Korea. This guideline is suggested to be disseminated to clinical nursing settings nationwide to improve the efficiency of intravenous infusion practice.

배경: 승모판막 질환에 동반된 심방세동의 경우 그 기간이 길면 승모판막 질환을 수술하여도 동성 율동으로 전환될 가능성이 매우 적다. 본 연구는 승모판막 질환에 동반된 심방세동에 대한 변형 Maze 수술후 장기 결과와 심방세도의 재발에 미치는 요인을 조사 하고자 하였다. 대상 및 방법: 1990년부터 1996년까지 승모판막 질환과 동반된 심방세동으로 외과적 요법을 시행받은 35명의 환자를 대상으로 하였다. 심방세동의 평균 유병기간은 평균 7.7$\pm$4.5년이었고 수술은 승모판막 대치술 34례(재수술 3례)와 승모판막 성형술 1례를 시행하였고 승모판 질환 수술 외에 동반 수술로는 삼첨판륜 성형술 4례, 삼첨판막 대치술 3례 였다. 심 방세동에 대한 수술은 좌측 폐정맥 부위는 격리하지 않는 변형 Maze 수술을 시행하였다. 수술 후 동성 율동으로 회복여부, 심방세동의 재발에 미치는 요인과 장기 결과를 분석하였다. 결과: 수술 직후 2례를 제외한 33례(93.9%)에서 동성율동으로 돌아왔으나 수술 후 퇴원 전에 12례에서 심방세동이 재발되었다. 수술환자중 1례에서 수술 후 3일에 동성 정지에 따른 심정지가 발생하여 소생되었으나 뇌손상으로 수술 후 15일에 사망하였다. 심방세동이 재발된 경우 수술 후 약 2개월에서 6개월 사이에 항부정맥 약물(mquinidine)과 전기적 제세동으로 치료하여 12례중 10례에서 동성 율동으로 돌아온 환자는 항부정맥 약물을 모두 중단하 였으며, 수술 후 3년에서 9년(평균 71.1$\pm$17.5개월) 추적 관찰 중 9례에서 심방세동이 재발되어 장기간 동성 율동이 유지된 환자는 34명중 25명으로 73.5%이었다. 승모판 질환이 있던 환자에서 수술 후 심방세동의 재발에 미치는 요인들을 조사한 결과 수술전 심방세동의 기간(동성율동 유지군 : 재발군=6.3년 : 10.3년, P=0.008)과 수술 전 단순 흉부 X선상 심흉비율(0.58 : 0.72, p=0.009)은 통계학적으로 유의하게 나타났으나 심초음파 검사상 좌심방의 직경(57.2mm : 77.4mm, p=0.106)은 통계학적 유의성이 없었다. 결론: 심방세동이 있는 환자에서 동반 질환 수술시 병행하여 수술한다면 정상 동성 율동으로 회복될 기회를 증가시킬 수 있는 유용한 수술법으로 생각된다. 그러나 수술후 재발률을 감소시키기 위하여 적절한 술기의 변형에 대한 연구와 약물요법의 병행을 고려하여야 할 것으로 사료된다.

Aspergillus Infection is a major.cause of mortality in individuals with depressed cell-mediated immunity. Despite therapy with intravenous amphotericin B and oral antifungal agents, high mortality has been reported among heart transplant recipients. We experienced two cases of pulmonary aspergillosis among 15 heart transplantation cases. Both cases were similiar in terms of age, time of diagnosis, and medication. Percutaneous needle aspiration biopsy revealed Aspergillus fumigatus in both cases. The thirst case showed multiple aspergilloma on both lung fields and were treated by IV Amphotericin B and oral itraconazole. After completion of treatment, the lesion completely disappeared and he has been followed up for more than one year in his good condition. The second case showed a single nodule on his right lower lung field and were treated by both medication and surgery. The patient recovered well and had been doing well until 4th postoperative month when he developed humoral rejection and expired.

Medical services should be provided not only to patients but also to medical staff who are the main actors of medical treatment. This paper is based on Ethnography, observing the behavior of medical staff performing medical actions and finding what is the most frequent of physical medical treatment. In particular, I observed the need for recognition and performance of the clinical workforce for invasive medical treatment. Based on the Insight from the observation and analysis of medical staff's behavior on intravenous fluid therapy and in-depth interview, I defined four design value factors. Plus, I suggest a design prototype with a proposal for designing a medical consumable kit for intravenous fluid therapy to validate the design elements. Kitting medical consumables simplify the preparation and disposal process throughout the treatment, enabling rapid medical action and increasing work efficiency.

Purpose: This study was conducted to develop and test the effects of a program for practice application of intravenous infusion evidence based nursing practice (EBP) guidelines in small and medium-sized hospitals. Methods: A mixed method research design was used, combining non-equivalent control group pre-post test design with qualitative study analysis. The subjects consisted of 55 nurses. The practice application program was developed based on the Advancing Research and Clinical practice through close Collaboration (ARCC) model. Data were collected for analysis in the following areas: nurses' EBP organizational culture and readiness, EBP beliefs, EBP implementation, importance about intravenous infusion, and performance about intravenous infusion, with data assessed using valid and reliable instruments. Patient outcomes were collected from the hospital's medical records. Data were analyzed using t-test, χ2-test, and Shapiro-Wilk test, with qualitative content analysis used for interview data. Results: Following the intervention, nurses' EBP organizational culture and readiness, EBP beliefs, EBP implementation, and performance of intravenous infusion and perceptions of its importance showed significant improvement in the experimental group. Phlebitis rates decreased in the experimental group compared to the control group. Conclusion: This program is effective to improve nurse's perception and practice of evidence based nursing. Therefore we recommend to use this program at same levels of hospitals.

내시경 시술 전 일시적으로 항응고제를 중단하는 것은 위장관 출혈의 위험과 혈전색전증의 위험 사이에 적절한 균형을 잡기 어렵기 때문에 논란의 여지가 많다. 와파린은 새로운 경구용 항응고제(direct oral anticoagulant agent, DOAC)보다 임상의에게 더 친숙하고, 효과를 쉽고 빠르게 전환시킬 수 있다는 장점이 있지만 복잡한 약역동학 특징과 좁은 치료적 범위 때문에 관리가 어렵다. 반면, DOAC는 약물의 모니터링 및 용량 조절 없이 정해진 용량으로 처방이 가능하며, 빠르게 작용하고, 반감기가 짧아 관리가 쉽지만 해독제가 없다는 단점이 있다. 이전 연구들에서 DOAC를 복용한 환자들은 와파린을 복용한 환자들보다 시술과 관련되지 않은 위장관 출혈의 위험이 높았다고 보고한 바 있다. 하지만 시술과 관련된 위장관 출혈 위험에 대하여는 알려진 바가 없는 실정이다. 미국이나 유럽 내시경 가이드라인들에서는 저위험 내시경 시술을 받는 환자들에서는 와파린과 DOAC를 유지하도록 권고하고 있으며, 고위험 시술의 경우에는 와파린를 사용하는 환자들에서 헤파린 교량 요법(heparin bridging)을 시행하도록 권고하고 있다. 임상적으로 DOAC를 사용하는 환자들 또한 혈전색전증을 예방하기 위하여 헤파린 교량 요법을 시행해볼 수 있는데, 와파린 및 DOAC의 헤파린 교량 요법과 관련된 출혈 및 혈전색전증 위험의 차이 또한 명확하지 않다. 따라서 저자들은 1) 와파린과 DOAC 치료를 받는 환자들에서의 출혈, 혈전색전증 및 사망의 위험을 비교하고자 하였으며, 2) 13종류의 고위험 내시경 시술 중에서 시술별 위험을 비교하고, 3) 헤파린 교량 요법이 합병증의 발생을 증가시키지 않는지 확인하고자 본 연구를 진행하였다. 일본 대규모 국가 입원 환자 데이터베이스를 이용하여 2014년 4월부터 2015년 5월까지 시술 전 와파린 또는 DOAC(rivaroxaban, apixaban, dabigatran, edoxaban)를 복용하고, 13종류의 고위험 내시경 시술을 시행받은 20세 이상의 성인 환자 총 16,977명을 확인하였다. 고위험 시술은 용종 절제술, 내시경 점막절제술, 내시경 점막하박리술, 협착 부위의 풍선확장술, 내시경 지혈술, 내시경 정맥결찰술, 내시경 주사 경화요법, 내시경 괄약근절개술, 내시경 초음파 유도하 미세침 흡인 검사, 경피적 위루술을 포함하였다. 일대일 성향 점수 매칭 분석(propensity score matching, 나이, 성별, 체질량 지수, 기저 질환, 병원의 규모, 시술의 종류, 약물의 종류를 매칭)을 시행하여 와파린군과 DOAC군에서 시술 위장관 출혈 및 혈전색전증, 사망의 발생을 비교하였다. 또한 경구항혈전제와 헤파린 교량 치료 시행 유무에 따라, DOAC 단독군, 와파린 단독군, DOAC와 헤파린 교량 요법군, 와파린과 헤파린 교량요법군으로 나누어, 하위군(subgroup) 분석을 시행하였다. 5,046쌍이 성향 점수 매칭 분석에 포함되었으며, 와파린군에서 DOAC군보다 통계적으로 의미 있게 위장관 출혈의 비율이 높았다(12.0% vs. 9.9% p=0.02). 혈전색전증 발생률(5.4% vs. 4.7%)과 입원중 사망률(5.4% vs. 4.7%)은 양 군에서 의미 있는 차이는 없었다. DOAC 종류별로 나누어 하위군 분석을 시행하였을 때, 와파린군은 rivaroxaban군에 비하여 위장관 출혈의 비율이 높았으며, rivaroxaban군, dabigatran군에 비하여 혈전색전증의 비율이 높았고, 입원 중 사망률에서는 의미 있는 차이는 없었다. 내시경 시술의 종류로 보정하였을 때 위장관 출혈 및 혈전색전증, 사망률은 DOAC 단독으로 치료한 환자에서보다 와파린과 헤파린 교량 요법(bridging) 또는 DOAC과 헤파린 교량 요법을 시행한 환자에서 높았다. 시술 종류 중에서는 위루관 삽입술에 비하여 내시경 점막하박리술, 내시경 점막절제술 및 내시경 정맥류결찰술, 내시경 주사경화요법을 시행한 환자에서 위장관 출혈의 위험이 가장 높았으며, 하부 내시경 점막절제술, 하부 용종 절제술, 내시경적 유두괄약근절제술 또는 내시경 초음파 유도하 미세침 흡인 검사는 중등도 위험을 보였다.

Purpose : Fluconazole prophylaxis for very low birth weight (VLBW) infants has been shown to reduce invasive fungal infection and its mortality. This study aims to evaluate the effect of fluconazole prophylaxis in VLBW infants on the incidence and mortality of fungal infection. Methods : VLBW infants with endotracheal intubation and central vascular access admitted to the Neonatal Intensive Care Unit (NICU) at Chonnam University Hospital were enrolled. Twenty eight infants of 7-month baseline period from January to July 2005 ('non-fluconazole group') were compared with 29 infants of a 7-month fluconazole period from January to July 2006 ('fluconazole group'). Results : Gestational age, birth weight, sex, mode of delivery, frequency of twin pregnancy, chorioamnionitis, antenatal steroid and rupture of membranes were similar between the fluconazole and non-fluconazole groups. The rate of extremely low birth weight (ELBW) infants, frequency and duration of prophylactic antibiotics, total parenteral nutrition and umbilical catheters, duration of intralipid, mechanical ventilation and nasal continuous positive airway pressure (CPAP) were also not significant. However, frequency of percutaneous central venous catheterization (PCVC) and intralipid administration, and duration of PCVC were significant between the two groups. The overall incidence and mortality of fungal infection were not different between the two groups. Although the Malassezia infection was increased in the fluconazole group (P<0.05), candida was significantly decreased compared to the non-fluconazole group (P<0.05). Conclusion : Fluconazole prophylaxis in high risk VLBW infants decreased the candida infection significantly. Antifungal prophylaxis is recommended in terms of cost effectiveness, but further study is needed to clarify the reason for the increase of Malassezia infection.

$\underline{Purpose}$: Combined modality therapy including chemotherapy, surgery and radiotherapy is considered the standard of care for the treatment of stage III non-small cell lung cancer (NSCLC). This study was conducted to evaluate the efficacy of paclitaxel and cisplatin with induction chemotherapy followed by concurrent chemoradiotherapy for stage IIIB NSCLC. $\underline{Materials\;and\;Methods}$: Between July 2000 and October 2005, thirty-nine patients with stage IIIB NSCLC were treated with two cycles of induction chemotherapy followed by concurrent chemoradiotherapy. The induction chemotherapy included the administration of paclitaxel ($175\;mg/m^2$) by intravenous infusion on day 1 and treatment with cisplatin ($75\;mg/m^2$) by intravenous infusion on day 1 every 3 weeks. Concurrent chemoradiotherapy included the use of paclitaxel ($60\;mg/m^2$) plus cisplatin ($25\;mg/m^2$) given intravenously for 6 weeks on day 43, 50, 57, 71, 78 and 85. Thoracic radiotherapy was delivered with 1.8 Gy daily fractions to a total dose of $54{\sim}59.4\;Gy$ in $6{\sim}7$ weeks (median: 59.4 Gy). $\underline{Results}$: The follow up period was $6{\sim}63$ months (median: 21 months). After the induction of chemotherapy, 41.0% (16 patients) showed a partial response and 59.0% (23 patients) had stable disease. After concurrent chemoradiotherapy, 10.3% (4 patients) had a complete response, 41.0% (16 patients) had a partial response, and the overall response rate was 51.3% (20 patients). The 1-, 2-, 3-year overall survival rates were 66.7%, 40.6%, and 27.4% respectively, with a median survival time of 20 months. The 1-, 2-, 3-year progression free survival rates were 43.6%, 24.6%, and 24.6%, respectively, with median progression free survival time of 10.7 months. Induction chemotherapy was well tolerated. Among 39 patients who completed the entire treatment including chemoradiotherapy, 46.3% (18 patients) had esophagitis greater than grade 3 and 28.2% (11 patients) had radiation pneumonitis greater than grade 3. $\underline{Conclusion}$: Paclitaxel and cisplatin with induction chemotherapy followed by concurrent chemoradiotherapy for stage IIIB NSCLC seems to be an effective treatment. Occurrence of esophagitis and pneumonitis represents a significant morbidity and suggests a modification of the treatment regimen, either with the chemotherapy schedule or with radiotherapy treatment planning.

Hormonal replacement therapy (HRT) has been proven for treatment of postmenopausal symptoms such as hot flushes, night sweats and urologic symptoms. HRT became very popular in the 1990's, when there were several reports showing that it also helped with other menopausal complications such as osteoporosis and cardiovascular disease. Recent studies report that the incidence of breast cancer, endometrial cancer, cerebral infarction, coronary artery diseases, deep vein thrombosis and pulmonary thrombembolism could rise after HRT. Among these side effects of HRT, the risk of pulmonary thromboembolism increases 2 to 4 fold after HRT, but can vary with the use of different doses and preparations. Here, we summarize the risk factors and clinical courses for 5 patients who developed pulmonary thromboembolism after postmenopausal HRT.

The purpose of this study is to evaluate the applicability of intravenous atropine sulfate therapy in infantile hypertrophic pyloric stenosis (IHPS). From 1998 to 2000 among 35 cases of IHPS, pyloromytomy was performed in 13 (Group A), and intravenous atropine was given as a primary therapy in 22 cases (Group B). In group A, all cases were cured completely. In group B, 13 (59 %) out of 22 cases were successfully treated with atropine, but 9 were failed therapy, and required operation. The recovery period to normal feeding and the hospital stay of the successful atropine group were longer than those of pyloromyotomy, 8.6 days vs. 2.9 days and 13.2 days vs. 4.1 days, respectively. In conclusion, intravenous atropine therapy did not replace pyloromyotomy, but it might be an alternative for the selected patients with contraindications for operation.
