  • 본 연구는 부적절한 영양지원이 ECMO 환자의 영양상태 뿐만 아니라 사망률 등에도 부정적인 영향을 미칠 수 있음을 보여주었다. 대부분의 ECMO 환자는 중환자실 입실 초기부터 영양상태가 이미 영양불량이거나 영양불량 위험군이었고, 재원기간이 경과하면서 악화되는 것을 관찰하였다. 이는 ECMO 환자들이 가장 위중할 때에 필요로 하는 칼로리와 단백질의 영양 지원이 충분하지 않았음을 시사하는 것이며, 특히 PN과 EN의 개시 시점이 영양관리지침의 권고보다 지연되지 않도록 노력하는 개선이 시급하다. 또한, ECMO 환자의 영양상태 평가만 아니라 공급한 영양지원에 대한 환자의 반응까지 고려한 영양관리가 필요한데, 이를 위해서는 영양관리가 중환자 간호에서 우선시 되어야 하며, 영양사를 포함한 다학제간 접근이 반드시 포함되어야 한다. 점차 증가하는 ECMO 적용 사례를 고려한다면, 중환자실에서의 집중치료 과정에 영양관리도 비중있게 반영되어야 할 것이다. 차후에는 전향적 무작위통제 연구로 환자의 질환 유형이나 ECMO 배치형태에 따른 영양지원방법과 효과를 비교할 것을 제안한다. 더 많은 대상자 수 확보를 위하여 여러 병원의 자료를 취합하여 분석하거나 환자 상태에 따라 영양공급의 적정량을 평가하고 비교하는 연구를 제안한다.

  • Purpose: The unique nature of life-and-death healthcare services sets them apart from other service industries. While many studies exist on the relationship between healthcare services and customer satisfaction, most of them focus on mildly ill patients, ignoring the differences between critically ill and non-seriously ill patients. This study discusses the actual quality of healthcare services for patients who are facing life-threatening illnesses and are on life support, as well as their right to protection and dignity. Methods: The survey conducted to 149 patients with the four major illnesses: cancer, heart disease, brain disease and rare and incurable disease, those who have experiences with senior general hospitals. Results: The basic statistics of this study are adequate to represent the four major critical illnesses, and the reliability and validity of this study's hypotheses, which were measured by multiple items, were analyzed, and the internal consistency was judged to be high. In addition, it was found that the convergent validity was good and the discriminant validity was also secured. When examining the goodness of fit of the hypotheses, the SRMR, which is the standardized root mean square of residuals that measures the difference between the covariance matrix of the data variables and the theoretical covariance matrix structure of the model, met the optimal criteria. Conclusion: The academic implications of this study are differentiated from other studies by moving away from evaluating the quality of healthcare services for mildly ill patients and focusing on the rights and dignity of patients with life-threatening illnesses in four senior general hospitals. In terms of academic implications, this study enriches the depth of related studies by demonstrating the right to protection and dignity as a factor of patient-centeredness based on physical environment quality, interaction quality, and outcome quality, which are presented as sub-factors of healthcare quality. We found that the three quality factors classified by Brady and Cronin (2001) are optimized for healthcare quality assessment and management, and that the results of patients' interaction quality assessment can be used to provide a comprehensive quality rating for hospitals. Health and human rights are inextricably linked, so assessing the degree to which rights and dignity are protected can be a superior and more comprehensive measurement tool than traditional health level measures for healthcare organizations. Practical implications: Improving the quality of the physical environment and the quality of outcomes is an important challenge for hospital managers who attract patients with life and death conditions, but given the scale and economics of time, money, and human inputs, improving the quality of interactions and defining them as performance indicators in hospital quality management is an efficient way to create maximum value in the short term.

  • Purpose: Despite the clinical and socio-economic impact of acute poisoned patients, many of the treatments are not standardized in Korea. Moreover, no formal training that is specifically focused on clinical toxicology exists. Rather, training and education are conducted case by case in various institutions. This study was conducted to develop a standardized simulation-based clinical toxicology training curriculum for healthcare providers. This program will focus on specific assessment and treatment of critical toxicology patients, specifically those who have been poisoned with organophosphate. Methods: The study was performed using a pre- and post-design to determine the effects of implementation of this program. The study was conducted at eight different urban teaching hospitals in a simulated room in the clinical area. The study was targeted to 19 groups composed of emergency residents and nurses. Simulation-based learning was conducted for each group. Results: All 19 groups achieved the minimum passing score of 75%. Implementation of the program led to improved performance rates for overall management and cooperative moods competency (p<0.01). Inter-rater agreement between the two evaluators was excellent. In general, the participants thought the program was realistic and were able to recognize and improve the competencies needed to care for organophosphate poisoned patients. Conclusion: Simulation-based learning is an effective educational strategy that can be applied to improving and understanding proper care for rare but critical patients. This program was effective at improving team performance and cooperative moods when managing an organophosphate poisoned patient in the Emergency Department.

  • Acute renal failure refers to a rapid reduction in renal function that usually occurs in an individual with no known previous renal disease. Development of a complication of acue renal failure in critically ill surgical patients is not unusual, and it causes high morbidity and mortality. Acute renal failure can be divided as Pre-renal (functional), Renal (organic), and Post-renal (obstructive) azotemia according to their etiologies. Early recognition and proper correction of pre-renal conditions are utter most important to prevent an organic damage of kidney. These measures include correction of dehydration, treatment of sepsis, and institution of shock therapy. Prolonged exposure to ischemia or nephrotoxin may lead a kidney to permanent parenchymal damage. A differential diagnosis between functional and organic acute renal failure may not be simple in many clinical settings. Renal functional parameters, such as $FENa^+$ or renal failure index, are may be of help in these situations for the differential diagnosis. Provocative test utilyzing mannitol, loop diuretics and renovascular dilators after restoration of renal circulation will give further benefits for diagnosis or for prevention of functional failure from leading to organic renal failure. Converting enzyme blocker, dopamine, calcium channel blocker, and propranolol are also reported to have some degree of renal protection from bioenergetic renal insults. Once diagnosis of acute tubular necrosis has been made, all measures should be utilized to maintain the patient until renal tubular regeneration occurs. Careful regulation of fluid, electrolyte, and acid-base balance is primary goal. Hyperkalemia over 6.5 mEq/l is a medical emergency and it should be corrected immediately. Various dosing schedules for medicines excreting through kidney have been suggested but none was proved safe and accurate. Therefore blood level of specific medicines better be checked before each dose, especially digoxin and Aminoglycosides. Indication for application of ultrafiltration hemofilter or dialysis may be made by individual base.

  • It has been suggested that mixed venous $O_{2}$ tension is a predicor of cardiac output especially in a critically ill patient after an open heart surgery. From April 1988 through September 1989, we monitored mixed venous $O_{2}$ tension and pulmonary arterial pressure in 48 patients with acyanotic congenital heart disease at postoperative 1 hour, 6 hour, 12 hour, 24 hour, and 48 hour respectively. They were divided into Group I, with severe pulmoary hypertension, and Group II, without severe pulmonary hypertension. In Group I, mixed venous $O_{2}$ tension and cardiac index showed significant increase with time (p<0.05), but the ratio of pulmonary-aortic systolic pressure didn't show significant change. The increase was significant only 24 hour after operation, and so this low cardiac performance in early postoperative period should be considered when postoperative management is being planned in the risky patient. In Group II, all of the three variables didn't show any significant change with time. The correlation coefficient between mixed venous $O_{2}$ tension and cardiac index was significantly different from zero in both Group I (p<0.001) and group II (p<0.05) at each imeperiod, but the ratio of pulmonary-aortic systolic pressure didn't correlated well with the other 2 variables. Our study showed that serial determination of mixed venous $O_{2}$ tension in acyanotic congenital heart disease could be used as a guide in estimating the cardiac index postoperatively.

  • Invasive pulmonary aspergillosis (IPA) is rarely reported in patients who have normal immune function. Recently, IPA risk was reported in nonimmunocompromised hosts, such as patients with chronic obstructive pulmonary disease and critically ill patients in intensive care units. Moreover, influenza infection is also believed to be associated with IPA among immunocompetent patients. However, most reports on IPA with influenza A infection, including pandemic influenza H1N1, and IPA associated with influenza B infection were scarcely reported. Here, we report probable IPA with a fatal clinical course in an immunocompetent patient with influenza B infection. We demonstrate IPA as a possible complication in immunocompetent patients with influenza B infection. Early clinical suspicion of IPA and timely antifungal therapy are required for better outcomes in such cases.

  • Vancomycin is a frequently used antibiotic in intensive care units, and the patient's renal clearance affects the pharmacokinetic characteristics of vancomycin. Several advantages have been reported for vancomycin continuous intravenous infusion, but studies on continuous dosing regimens based on patients' renal clearance are insufficient. The aim of this study was to develop a vancomycin serum concentration prediction model by factoring in a patient's renal clearance. Children admitted to our institution between July 1, 2021, and July 31, 2022 with records of continuous infusion of vancomycin were included in the study. Sex, age, height, weight, vancomycin dose by weight, interval from the start of vancomycin administration to the time of therapeutic drug monitoring sampling, and vancomycin serum concentrations were analyzed with the linear regression analysis of the mixed effect model. Univariable regression analysis was performed using the vancomycin serum concentration as a dependent variable. It showed that vancomycin dose (p < 0.001) and serum creatinine (p = 0.007) were factors that had the most impact on vancomycin serum concentration. Vancomycin serum concentration was affected by vancomycin dose (p < 0.001) and serum creatinine (p = 0.001) with statistical significance, and a multivariable regression model was obtained as follows: Vancomycin serum concentration (mg/l) = -1.296 + 0.281 × vancomycin dose (mg/kg) + 20.458 × serum creatinine (mg/dl) (adjusted coefficient of determination, R2 = 0.66). This prediction model is expected to contribute to establishing an optimal continuous infusion regimen for vancomycin.

  • Background: Serum procalcitonin level has been considered prognostic during sepsis and septic shock. We investigated the significance of procalcitonin in critically ill patients with respiratory infections. Methods: The patients who had radiographically diagnosed diffuse lung infiltrations were enrolled on a prospective basis. Bronchoalveolar lavage (BAL) fluid for the purpose of quantitative cultures (${\geq}10^4$ cfu/mL) was obtained from all patients. Serum procalcitonin levels determined by PCT-Q kit were measured on BAL day and classified as follows; <0.5 ng/mL, 0.5~2.0 ng/mL, 2.0~10.0 ng/mL and >10.0 ng/mL. We analyzed the patient's characteristics according to outcome; favorable or unfavorable, defined as death. Results: Patients from the following categories were included: medical 17 (47.2%), surgical 9 (25%), and burned 10 (27.8%). APACHE II scores on admission to intensive care unit were 11.5${\pm}$6.89 and 11 (30.6%) had unfavorable outcomes. A procalcitonin level ${\geq}$0.5 ng/mL was in 17 (47.2%) of all. On univariate analysis, the frequencies of burn injury, mechanical ventilation, multiple organ failure, and a procalcitonin level ${\geq}$0.5 ng/mL were more often increased in patients with unfavorable outcomes than in those with favorable outcomes (p<.05). Also, a higher procalcitonin range and ventilator-associated pneumonia (VAP) were more closely associated with an unfavorable outcome (p<.05). However in multivariate analysis, a strong predictor of unfavorable outcome was burn injury (p<.05). A procalcitonin level ${\geq}$0.5 ng/mL was more sensitive in predicting VAP than unfavorable outcome. Conclusion: A higher procalcitonin level seems to be associated with VAP, but further study is required to know that procalcitonin would be a prognostic marker in critically ill patients with respiratory infections.

  • 중환자실에 입원한 환자들의 구강위생은 매우 중요한 문제이다. 중환자들은 기본적으로 면역이 저하된 환자들로 각종 병원성 세균들에 의한 감염의 기회가 높기 때문이다. 구강문제는 감염의 1차 방어선인 구강이 감염의 우선적인 부위로 작용될 뿐 아니라 전신감염을 초래하기도 한다. 본 연구에서는 중증환자의 구강청소를 용이하게 하는 마우스 피스 형태의 새로운 진공 구강 세정기 설계에 관한 연구를 수행하였다. 이중 구조 방식의 세정기와 표준 치아 모델로써 3D CAD 모델링 및 유동해석 모델을 수립하고 압력 및 유동특성을 분석하였다. 세정기 내부의 압력은 거의 일정한 분포를 보였으나, 속력분포의 경우 치아 안쪽과 바깥쪽에서 큰 차이를 보였다. 치아 안쪽에서도 가운데 부분의 속도가 가장 높고 가운데에서 멀어질수록 속력이 감소하는 특성을 보였다. 세정기의 흡입관과 배출관을 바꾸어 해석한 결과 치아 바깥쪽 가운데 부분의 속도가 가장 높게 나타났다. 세정기의 효과를 높이기 위해서 흡입-배출을 교대로 바꾸는 교번식을 제안하고, 어금니 부위의 속력을 높이는 설계 보완이 요구된다.

  • 소아에서 급성 신손상의 흔한 원인들로는 신허혈, 신독성 약물들, 그리고 패혈증 등이 있으며, 신대체요법 시작시의 저혈압, 신대체 요법 동안 승압제의 사용, 그리고 신대체 요법 시작시의 수액 과부하 정도가 환자의 생존(소아 중환자실 퇴원)에 영향을 미치는 요인들로 알려져 있다. 지속적 신대체 요법의 빠른 시작은 급성 신손상을 가진 환자들에게서 사망률과 예후에 나쁜 영향을 미치는 수액 과부하를 감소시키는 것으로 보고되었다. 이에 저자들은 소아 환자에게서 지속적 신대체 요법의 실제 처방과 급성 신손상, 수액 과부하, 그리고 지속적 신대체 요법간의 연관성 및 치료결과를 살펴보고자 한다. 결론적으로, 급성 신손상을 가진 소아의 치료에 있어서 과도한 수액 과부하가 발생하기 전에 빠른 지속적 신대체 요법의 시작이 필요하다고 제시하는 바이다.
