Resuscitation Fluid Use in a Single Surgical Intensive Care Unit

Purpose@#The aim of this study was to analyze the temporal change of resuscitation fluid use based on all fluids administered in a surgical intensive care unit (ICU). @*Methods@#The administration of resuscitation fluid to all patients admitted to a surgical ICU of a tertiary referral hospital was investigated from 2008 to 2015. The types and volumes of fluid, and laboratory data taken within 7 days after ICU admission were evaluated. Resuscitation fluids were defined as fluids infused according to stat orders, rather than routine orders. @*Results@#There were a total of 8,885 admissions to the ICU for 7,886 patients. The volumetric proportion of crystalloid to total resuscitation fluids increased significantly over the study period (p < 0.001; 79.6% in 2008; 93.7% in 2015). Although the proportion of 0.9% saline to crystalloids decreased, that of balanced solutions increased (p < 0.001; 29.5% in 2008; 55.6% in 2015). The use of colloids decreased from 20.4% in 2008, to 6.3% in 2015 (p < 0.001). Proportions calculated using the number of individual fluids administered revealed trends similar to those calculated using volumetric data. The amount of infused 0.9% saline was weakly correlated with the lowest blood pH and the highest serum chloride levels (ρ = -0.26 and 0.19, respectively). @*Conclusion@#Changes in the trends of fluid resuscitation practice were noted in a single surgical ICU over the 8-year study period. Crystalloid use increased owing to a rise in the utilization of balanced solutions with a downward trend in colloid use.

Clinical Characteristics and Outcomes of Patients with Culture-Negative Pyogenic Spondylitis according to Empiric Glycopeptide Use / 감염과화학요법

BACKGROUND@#The optimal choice of antibiotics is challenging in culture-negative pyogenic spondylitis (PS). The empiric use of glycopeptides is suggested depending on various risk factors, although clinical data are sparse. This study aimed to analyze the clinical characteristics and outcomes of patients with culture-negative PS and evaluate the effect of empiric glycopeptide use on clinical outcomes in these patients.@*MATERIALS AND METHODS@#Data on the characteristics, treatment, and outcomes of 175 patients diagnosed with PS were retrospectively obtained from the electronic database of a tertiary referral hospital from 2009 to 2016. Patients with negative culture results were grouped by the duration of glycopeptide treatment: glycopeptide therapy <28 days (Group A) and glycopeptide therapy ≥28 days (Group B).@*RESULTS@#Of 89 patients with negative culture results, 78 were included in the analysis (Group A, n = 66; Group B, n = 12). The mean age of patients with negative culture results was 65.5 years, and 52.6% were male. The median follow-up duration was 573 (interquartile range [IQR], 83 – 1,037) days. The duration of intravenous glycopeptide therapy was 0.0 (IQR, 0.0 – 0.0) days and 55.5 (IQR, 37.0 – 75.7) days for Groups A and B, respectively. Patients who used glycopeptide longer empirically (Group B) had more commonly undergone a previous spinal procedure, including surgery (P = 0.024). The length of hospitalization, erythrocyte sedimentation rate, and C-reactive protein level were significantly higher in Group B compared with those in Group A (P <0.001, P <0.001, and P = 0.006, respectively). Regarding treatment modalities, patients in Group B underwent surgery more frequently (P = 0.017). The duration of parenteral antibiotic treatment was longer in Group B (P <0.001). Recurrence was noted in 7 patients (9.0%), and the recurrence rate was not significantly different between the 2 groups (Group A, 5/66 [7.6%]; Group B, 2/12 [16.7%]; P = 0.293).@*CONCLUSION@#The recurrence rate among patients with culture-negative PS was not different based on the duration of empiric glycopeptide use. However, considering the small sample size and heterogeneity of our study population, we suggest that it is reasonable to administer glycopeptide antibiotics in these patients depending on clinical risk factors. Further large-scale prospective studies are needed to obtain more evidence for appropriate antibiotic treatment.

The job competency of radiological technologists in Korea based on specialists opinion and questionnaire survey / 보건의료교육평가

PURPOSE: Although there are over 40,000 licensed radiological technologists (RTs) in Korea, job competency standards have yet to be defined. This study aims to clarify the job competency of Korean RTs. METHODS: A task force team of 11 professional RTs were recruited in order to analyze the job competency of domestic and international RTs. A draft for the job competency of Korean RTs was prepared. A survey was then conducted sampling RTs and the attitudes of their competencies were recorded from May 21 to July 30, 2016. RESULTS: We identified five modules of professionalism, patient management, health and safety, operation of equipment, and procedure management and 131 detailed job competencies for RTs in Korea. “Health and safety” had the highest average score and “professionalism” had the lowest average score for both job performance and importance. The content validity ratios for the 131 subcompetencies were mostly valid. CONCLUSION: Establishment of standard guidelines for RT job competency for multidisciplinary healthcare at medical institutions may be possible based on our results, which will help educators of RT training institutions to clarify their training and education.

Diffuse Pulmonary Ossification Developing in Patients with End-stage Renal Disease / 대한내과학회지

Diffuse pulmonary ossification (DPO) is a rare condition characterized by chronic metaplastic ossification of the lung parenchyma. DPO is associated with various underlying pulmonary, cardiac, and systemic diseases. However, to our knowledge, DPO has rarely been described in patients with end-stage renal disease undergoing hemodialysis. We describe two cases of DPO diagnosed in long-term hemodialysis patients. Awareness of this rare disorder is required for a better differential diagnosis of cases presenting with bilateral diffuse micronodular lesions, including calcific opacities.

Chylous Ascites in a Patient with Sepsis Caused by Bilateral Pneumonia / 대한구급학회지

Chylous ascites is a rare form of ascites characterized by milky peritoneal fluid rich in triglycerides due to the accumulation of chyle in the peritoneal cavity. This affliction occurs as a result of a disruption of lymph flow associated with traumatic injury or obstruction of the lymphatic system. There are various causes of chylous ascites, such as lymphatic anomalies, malignancy, cirrhosis, infection, trauma, surgery, and nephrotic syndrome. We report a rare case of an 81-year-old male with sepsis caused by bilateral pneumonia who presented with chylous ascites.

Clinical Relevance of Bronchial Anthracofibrosis in Patients with Chronic Obstructive Pulmonary Disease Exacerbation / 결핵및호흡기질환

BACKGROUND: Bronchial anthracofibrosis (BAF), which is associated with exposure to biomass smoke in inefficiently ventilated indoor areas, can take the form of obstructive lung disease. Patients with BAF can mimic or present with an exacerbation of chronic obstructive pulmonary disease (COPD). The purpose of the current study was to investigate the prevalence of BAF in Korean patients with COPD exacerbation as well as to examine the clinical features of these patients in order to determine its clinical relevance. METHODS: A total of 206 patients with COPD exacerbation were divided into BAF and non-BAF groups, according to computed tomography findings. We compared both clinical and radiologic variables between the two groups. RESULTS: Patients with BAF (51 [25%]) were older, with a preponderance of nonsmoking women; moreover, they showed a more frequent association with exposure to wood smoke compared to those without BAF. However, no differences in the severity of illness and clinical course between the two groups were observed. Patients in the BAF group had less severe airflow obstruction, but more common and severe pulmonary hypertension signs than those in the non-BAF group. CONCLUSION: Compared with non-BAF COPD, BAF may be associated with milder airflow limitation and more frequent signs of pulmonary hypertension with a more severe grade in patients presenting with COPD exacerbation.
