BACKGROUND: The effectiveness of surveillance to identify extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E) carriers is controversial during a non-outbreak situation. We performed additional stool cultures for ESBL-E among intensive care unit (ICU) patients already under active surveillance by means of sputum and urine cultures. We aimed to assess the efficacy of stool cultures for screening for ESBL-E in a non-outbreak situation. METHODS: We conducted a retrospective cohort study in an ICU. Sputum and urine samples were cultured for ESBL-E surveillance purposes from January to September 2013 (phase 1). Stool cultures were routinely performed in addition from January to September 2014 (phase 2). Antimicrobial use density values and clinical outcomes were investigated and compared between phase 1 and 2. RESULTS: We identified 512 and 478 patients in phase 1 and phase 2, respectively. ESBL-E were found in the feces of 65 (13.6%) patients in phase 2. The antimicrobial use density values (expressed as defined daily doses per 1,000 bed-days) were not significantly different between the two phases for fluoroquinolones (7 vs. 10, p = 0.376), third-generation cephalosporins (24.2 vs. 29.5, p = 0.724), tazobactam/piperacillin (44.6 vs. 57.3, p = 0.489), and carbapenems (73 vs. 55.5, p = 0.222). Moreover, there were no significant differences in ICU mortality and length of stay (11.5% vs. 9.8%, p = 0.412, and 9 vs. 10 days, p = 0.28, respectively). CONCLUSIONS: Stool culture seemed ineffective in improving the antimicrobial use density of broad-spectrum antimicrobials, clinical outcomes, and ICU length of stay, and is not recommended for surveillance of ESBL-E in a non-outbreak situation.

BACKGROUND: Several antibiotics can be used to treat ventilator-associated pneumonia caused by carbapenem-resistant A. baumannii (CRAB-VAP) including high-dose sulbactam. However, the effectiveness of high-dose sulbactam therapy is not well known. We report our experience with high-dose sulbactam for treatment of CRAB-VAP. METHODS: Medical records of patients with CRAB-VAP who were given high-dose sulbactam between May 2013 and June 2015 were reviewed. RESULTS: Fifty-eight patients with CRAB-VAP were treated with high-dose sulbactam. The mean age was 72.0 ± 15.2 years, and the acute physiology and chronic health evaluation II (APACHE II) score was 15.1 ± 5.10 at the time of CRAB-VAP diagnosis. Early clinical improvement was observed in 65.5% of patients, and 30-day mortality was 29.3%. Early clinical failure (odds ratio [OR]: 8.720, confidence interval [CI]: 1.346-56.484; p = 0.023) and APACHE II score ≥ 14 at CRAB-VAP diagnosis (OR: 10.934, CI: 1.047-114.148; p = 0.046) were associated with 30-day mortality. CONCLUSIONS: High-dose sulbactam therapy may be effective for the treatment of CRAB-VAP. However, early clinical failure was observed in 35% of patients and was associated with poor outcome.

BACKGROUND: To identify the prevalence and related factors for vitamin D deficiency in the patients who admitted to the medical intensive care unit (ICU) of a Korean tertiary care hospital. METHODS: We retrospectively analyzed the data from ICU patients requiring mechanical ventilation (MV) for a period of > 48 h to identify the prevalence and associated factors for vitamin D deficiency. Vitamin D deficiency was defined as serum 25-hydroxyvitamin D [25(OH)D] level < 20 ng/mL. RESULTS: Among 570 patients admitted to the ICU, 221 were enrolled in the study, 194 in the vitamin D deficient group and 27 in the non-deficient group. Prevalence of vitamin D deficiency in critically ill patients was 87.8%. The patient age was lower in the vitamin D deficient group compared with the non-deficient group (64.4 ± 15.4 vs. 71.0 ± 9.6 years, p = 0.049). A higher acute physiology and chronic health evaluation II (APACHE II) score (odds ratio [OR] 1.23, 95% confidence interval [CI] 1.10-1.37) and chronic illness (OR 3.12, 95% CI 1.08-9.01) were associated with vitamin D deficiency after adjusting for age and body mass index. Clinical outcomes of duration of MV, ICU stay, and 28- and 90-day mortality rates were not significantly different between the vitamin D deficient and nondeficient groups. CONCLUSIONS: Vitamin D deficiency was common in critically ill patients, particularly among younger patients. Higher APACHE II score and chronic illness were associated with vitamin D deficiency.

4.The Complexities of Intravenous Fluid Research: Questions of Scale, Volume, and Accumulation.

Korean Journal of Critical Care Medicine 2016;31(4):276-299
Despite near ubiquity, information regarding fluids consumption at a health care systems level, and patient exposure at an individual level, is surprisingly limited in the medical literature. The epidemiology of the foundational medical intervention of intravenous fluid administration is incredibly complex, with millions of patients being exposed internationally every year. Fluid is being given for different reasons, to different targets, following different triggers, by different specialties in different countries, and any observations that can be made are thought to have limited external validity to other jurisdictions and patient groups. The independent effects of fluid administration and fluid accumulation are very hard to separate from other markers of illness severity and aspects of the process of care. Fluid accumulation can result in organ injury, even when the fluid is being given to purportedly ameliorate or prevent such injury, and if it were independently associated with mortality then would be an easily accessible and modifiable risk factor for subsequent morbidity or death. Despite their ubiquity, it is clear that we have limited understanding of the effects of the intravenous fluids we use daily in the most vulnerable of patient groups. The research agenda in this field is large and urgent.

5.How Do I Integrate Hemodynamic Variables When Managing Septic Shock?.
Olfa HAMZAOUI ; Jean Louis TEBOUL
Korean Journal of Critical Care Medicine 2016;31(4):265-275
Hemodynamic management of sepsis-induced circulatory failure is complex since this pathological state includes multiple cardiovascular derangements that can vary from patient to patient according to the degree of hypovolemia, of vascular tone depression, of myocardial depression and of microvascular dysfunction. The treatment of the sepsis-induced circulatory failure is thus not univocal and should be adapted on an individual basis. As physical examination is insufficient to obtain a comprehensive picture of the hemodynamic status, numerous hemodynamic variables more or less invasively collected, have been proposed to well assess the severity of each component of the circulatory failure and to monitor the response to therapy. In this article, we first describe the hemodynamic variables, which are the most relevant to be used, emphasizing on their physiological meaning, their validation and their limitations in patients with septic shock. We then proposed a general approach for managing patients with septic shock by describing the logical steps that need to be followed in order to select and deliver the most appropriate therapies. This therapeutic approach is essentially based on knowledge of physiology, of pathophysiology of sepsis, and of published data from clinical studies that addressed the issue of hemodynamic management of septic shock.

6.Central Venous Catheter-Related Hydrothorax.
Korean Journal of Critical Care Medicine 2015;30(4):343-348
This report describes a case of 88-year-old women who developed central venous catheter-related bilateral hydrothorax, in which left pleural effusion, while right pleural effusion was being drained. The drainage prevented accumulation of fluid in the right pleural space, indicating that there was neither extravasation of infusion fluid nor connection between the two pleural cavities. The only explanation for bilateral hydrothorax in this case is lymphatic connections. Although vascular injuries by central venous catheter can cause catheter-related hydrothorax, it is most likely that the positioning of the tip of central venous catheter within the lymphatic duct opening in the right subclavian-jugular confluence or superior vena cava causes the catheter-related hydrothorax. Pericardial effusion can also result from retrograde lymphatic flow through the pulmonary lymphatic chains.

The precise mechanism involved in DIC and delayed traumatic subarachnoid hemorrhage (DT-SAH) remains unclear in multiple-trauma patients. Hereby, we describe a polytraumatized patient with DIC who died due to DT-SAH. A 75-year-old female patient was admitted to our Emergency Department complaining of abdominal pain and drowsiness after a pedestrian accident. Her initial brain computerized tomography (CT) finding was negative for intracranial injury. However, her abdominal CT scan revealed a collection of retroperitoneal hematomas from internal iliac artery bleeding after a compressive pelvic fracture. This event eventually resulted in shock and DIC. An immediate angiographic embolization of the bleeding artery was performed along with transfusion and anti-thrombin III. Her vital signs were stabilized without neurological change. Fourteen hours after admission, she suddenly became comatose, and her follow-up brain CT scan revealed a dense DT-SAH along the basal cisterns with acute hydrocephalus. This event rapidly prompted brain CT angiography and digital subtraction angiography, which both confirmed the absence of any cerebrovascular abnormality. Despite emergency extraventricular drainage to reverse the hydrocephalus, the patient died three days after the trauma. This paper presents an unusual case of DT-SAH in a polytraumatized patient with DIC.

Phacomatosis pigmentovascularis (PPV) is a rare syndrome characterized by concurrent nevus flammeus (capillary malformation) and pigmentary nevus. According to current research, the major pathophysiologic mechanism in PPV is venous dysplasia with resultant compensatory collateral channels and venous hypertension. Arterial involvement is rare. We herein report our experience on renovascular hypertension, intermittent claudication, and severe rhabdomyolysis due to diffuse stenosis of multiple arteries in a patient with PPV type IIb associated with SWS.

Rupture of the lumbar artery is usually associated with trauma but rarely has been reported in association with anticoagulation. We present a 71-year-old man who developed spontaneous rupture of the lumbar artery leading to a retroperitoneal hematoma while receiving continuous renal replacement therapy (CRRT). The bleeding was confirmed by computed tomography and angiography and was controlled successfully using selective angiographic embolization. We suggest that spontaneous retroperitoneal bleeding should be considered in a case of sudden decrease in hemoglobin in a CRRT patient.
