In this prospective study, factors contributing to the development of decubitus ulcers were examined. Factors were identified by a literature review and a conceptual framework was developed. Regular observations were made during the subjects' hospitalization to determine the incidence of decubitus ulcers, and to assess other decubitus ulcer risk factors. Seventeen out of 146 admitted for neurological problems patients developed decubitus ulcers during the three month study period. There were no significant differences in the level of serum albumin, hemoglobin or age between those who developed decubitus ulcers and those who did not. There also was no difference in incidence between patient who were paralyzed and those not paralyzed. Mean hospitalization days until decubitus ulcer development was 6.5 days. According to the results of discriminant analysis, four factors -1) friction and shear, 2) sensory perceptual impairment, 3) low diastolic pressure, and 4) multiple use of sedative medications - predicted 84.93% of decubitus ulcer Incidence.

간담도 스캔은 방사성의약품을 정맥주사 후 간세포에 섭취되어 담즙과 함께 담낭과 담도를 통하여 십이지장으로 배출되는 양상을 경시적으로 검사한다. 따라서 간세포와 담낭의 기능 정도 및 담도계의 폐쇄 여부를 알 수 있고 담즙의 누출 유무, 위치 및 정도를 확인하는데 가장 예민한 검사 방법이다. 하지만 담즙 누출을 확인하기 위한 목적의 간담도 스캔은 누출된 담즙과 장으로 배출된 담즙의 구분이 명확하지 않다. 그래서 본 연구는 간담도 스캔 검사 시 양측와위 자세로 검사를 시행하여 누출된 담즙과 장으로 배출 된 방사능을 분리 구분하여 더욱 명확한 담즙 누출의 진단을 하는데 목적을 두고 있다. 총 31명의 환자 중 남자는 14명, 여자는 17명이고, 평균나이는 $51.1{\pm}14.4$세였다. 정상위 자세에서 1분씩 60분간 경시적 영상을 획득하고, 지연검사는 2시간, 4시간, 24시간 간격의 정상위 자세와 좌우 측와위 자세로 각각 5분 동안 영상을 획득하였다. 단, 측와위 자세의 영상 획득 시 약 5분간 측와위 자세를 유지한 후에 영상을 획득 하였다. 간담도 스캔 시 담즙 누출 환자에서의 양측와위 자세의 유용성을 알아보기 위해 정상위 검사에서 누출이 바로 확인되는 환자의 측와위 자세와 관심영역을 비교하여 누출 여부(크기, 위치, 농도)의 감별 편리성의 양상을 비교하였고, 의심되는 질환이 담즙 누출이지만 경시적 영상에서 누출부위를 확실히 구분할 수 없는 환자의 측와위 자세를 통해 누출부위를 우선적으로 식별할 수 있는 환자가 어느 정도인지를 검사대비 감별확률로 비교하였다. 31명의 담즙 누출 환자 중 23명의 환자는 기능영상 혹은 지연영상에서 담즙 누출을 확인하였고, 8명의 환자는 측와위에서 담즙 누출을 확인 할 수 있었다. 영상에서 해부학적으로 누출 위치를 찾는 것은 정상위가 더욱 용이하였으나, 양측와 위 자세 변동으로 인한 장내 담즙의 이동으로 담즙의 누출이 더욱 확실히 구분되었다. 또한 관심영역과 배후방사능의 섭취계수(Counts/Pixel)를 구하여 관심영역/배후방사능비를 평가결과, 평균은 정상위 5.02, 좌측와위 2.08, 우측와위 2.68이었다. 관심영역의 화소 수를 분석하여 크기를 비교할 경우, 좌측와위는 정상위에 비해 평균 1.91배 컸고, 우측와위는 평균 1.05배 컸다. 결과적으로 31명의 환자 중 38.5% 정도만이 측와위가 의미가 있었지만, 위치 변동으로 인해 장내 담즙의 이동으로 누출의 위치는 더욱 명확한 구분이 가능하였다. 또한 그 38.5%의 환자에서 정상위와 양측와위에서의 관심영역/배후방사능비, 관심영역의 크기를 비교하면 측와위에서 관심영역의 넓이는 좌측와위 19%, 우측와위 5% 넓어지고, 농도는 좌측와위 약 60%, 우측와위 약 50% 옅어졌으며, 이는 복강 내로 관심영역의 담즙누출을 의미한다고 할 수 있다. 간담도 검사시 담즙 누출을 의심하는 환자에게 양측와위 자세를 추가하여 검사를 한다면 담즙 누출을 정확하게 진단할 것으로 사료된다.

This study is to evaluate the decubitus ulcer healing effect of occlusive dressing with hydrocolloid and traditional dry dressing for home care nursing clients. Study design was quasi-experimental pre-post test design. Control group(15 person) was treated decubitus wound with traditional dry gauze dressing, and experimental group(17 persons) was treated decubitus ulcer with occlusive dressing with hydrocolloid and calcium alginate(17 persons). Study period was from 8/1/97 to 12/31/97. Subject subjects was 17 males and 15 females with 2nd phase over decubitus ulcer aged 30 to 70 who have been registered as home care nursing clients in Nurse's Association in Seoul city. Outcome variables were stages, size of decubitus ulcer, pain at dressing time and exudate amount. Study result as follows. Occlusive dressing with hydrocolloid was superior to traditional gauze dressing decreasing ulcer size and phase, and shortening treatment period. Dressing change of occlusive dressing was easier than that of traditional gauze dressing. In conclusion, occlusive dressing was recommended to treat decubitus ulcer in home care patients even if hydrocolloid is expensive to gauze dressing because of treatment effect and easeness of dressing.

Decubitus ulcer is a pressure-induced ulceration of the skin occurring in persons confined to bed for long periods of time. In order to prevent decubitus ulcer, the medical bed mechanism to minimize pressure, friction, and shear forces acting between bed and patient had been developed. Air mattress also can be effective for reducing pressure over bony prominence. In this study, motion analysis was performed to examine whether this bed mechanism functioned properly in case of using air mattress, which was much thicker than common hospital mattress. We found that the patient on the air mattress above the medical bed for preventing decubitus ulcer slipped upward and downward excessively as the general motored-bed. New bed mechanisms were synthesized kinematically using simple 4-bar and 6-bar linkages so as to reduce sliding between the bed and the patient on the air mattress for preventing decubitus ulcer.

Because patients with coronary artery disease (CAD) have depressed vagal modulation and the mortality risk from acute myocardial infarction is lower in patients with higher vagal modulation, methods that can increase vagal modulation are desirable in patients with CAD. We intended to inspect the effect of recumbent posture on vagal modulation. By using angiography, 33 patients with abnormal (CAD group) and 33 patients with normal coronary arteries (control group) were studied. The nonlinear as well as the linear characteristics of heart rate variability (HRV) were analyzed on these patients in three recumbent postures: namely, the supine, right lateral decubitus, and left lateral decubitus postures. The lower the normalized high-frequency power (nHF) in the supine or left lateral decubitus posture, the higher the increase in the nHF when the posture was changed from supine or left lateral decubitus to right lateral decubitus in both groups of patients. Right lateral decubitus posture can lead to the highest vagal modulation and the lowest sympathetic modulation among the three recumbent postures in both normal and patients with CAD. Therefore, the right lateral decubitus posture can be used as an effective physiologic vagal enhancer in patients with CAD.

Chest lateral decubitus 촬영은 일반적으로 PA 검사를 시행하여 왔으나, 응급환자나 몸이 불편한 환자의 검사에 있어 많은 불편이 있었다. 이에 본 연구에서는 AP 검사와 PA 검사를 비교하여 영상의 질, 환자의 안전성, 검사 효율성을 분석하고 두 검사간의 유용성을 알아보고자 하였다. 본원에서 2011.10.1 ~ 2012.7.30까지 늑막염 또는 기흉으로 의심되거나 진단된 환자들 중 chest lateral decubitus 촬영을 시행한 30명(남자 20명, 여자 10명)을 대상으로 하였다. 영상 화질 평가방법은 폐야의 미세구조, 진단영역의 넓음, air-fluid 경계면의 명확 유무, 환자 회전유무, 심장음영과 횡격막의 선명유무를 기준으로 하였으며, 영상의학과 전문의 2명, 호흡기내과 전공의 2명이 blind test로 평가하였다. 환자 안정성 및 방사선 검사의 효율성 평가는 환자 position의 안정성, 환자 상태 확인 등의 기준으로 일반촬영 5년 이상 경력의 방사선사 15명이 5점 척도로 평가를 하였고, 통계 분석은 Paired T-test로 분석하였다. Chest decubitus 촬영 시 AP와 PA자세에 따른 검사의 유용성을 비교 분석한 결과 영상의 화질에서 AP와 PA자세는 큰 차이가 없었던 반면, 환자의 안정성 및 방사선사의 검사 효율성에 있어 PA자세에 비해 AP자세의 평가 점수가 높게 나타났다. 이에 특별히 PA자세가 요구되지 않는다면 AP자세로 검사하여도 무방할 것으로 사료된다.

It is widely recognized that manipulation of body position takes advantage of the influences of gravity for improving oxygenation. The study aims to determine the effects of positioning(supine, prone, right lateral decubitus and left lateral decubitus positions) applied to the mechanically ventilatory acute respiratory failure patients on arterial oxygen partial pressure($PaO_2$), alveolar arterial oxygen tension difference($AaDO_2$), mean aterial pressure, peak inspiratory pressure and plateau pressure. Thirty two acute respiratory failure patients admitted to the medical intensive care unit at Kangnam St. Mary's Hospital, The Catholic University of Korea from March 1997 to January 1998, were divided into three groups by radiographic evidence of unilateral or bilateral lung disease. In group 1 with dominant right lung disease were twelve subjects, group 2 with dominant left lung disease had eight subjects and group 3 had twelve subjects with bilateral lung disease. The variables were measured in 30 minutes after each position of supine, prone, good lung down lateral decubitus and sick lung down lateral decubitus position. The position order was done at random by Latin squre design. The results are as follows; 1) With group 1 patients, the $PaO_2$ in the left lateral decubitus and prone position were $126.8{\pm}30.8$ mmHg and $106.7{\pm}36.8$ mmHg, respectively(p=0.0001). 2) With group 2 patients, the $PaO_2$ in the prone and the right lateral decubitus position were $121.7{\pm}44.7$ mmHg and $118.5{\pm}31.7$ mmHg, respectively (p=0.0018). 3) With group 3 patients, the $PaO_2$ was $143.6{\pm}36.6$ mmHg in the prone position (p=0.0001). 4) With group 1 patients, the $AaDO_2$ in the left lateral decubitus and the right lateral decubitus position were $178.1{\pm}29.7$ mmHg and $233.1{\pm}24.4$ mmHg, respectively(p=0.0001). 5) With group 2 patients, the $AaDO_2$ in the prone and the left lateral decubitus postion were $184.0{\pm}39.5$ mmHg and $231.0{\pm}23.9$ mmHg, respectively(p=0.0019). 6) With group 3 patients, the $AaDO_2$ in the prone and the supine postion were $377.1{\pm}35.6$ mmHg and $435.7{\pm}13.1$ mmHg, respectively (p=0.0001). 7) There were no differences among the mean arterial pressure, peak inspiratory pressure and plateau pressure for each of the supine, prone, left lateral decubitus and right lateral decubitus position. The results suggest that oxygenation may improve in mechanically ventilatory patients with unilateral lung disease when the position is good lung dependent and prone, and patients with bilateral lung disease when the position is prone without any effects on the mean arterial pressure and airway pressure. It is suggested that body positions improve ventilation/perfusion matching and oxygenation need to be specified in patient care plans.
