Invasive aspergillosis (IA) is most commonly seen in patients with risk factors, such as cytotoxic chemotherapy, prolonged neutropenia, corticosteroids, transplantation and acquired immune deficiency syndrome. IA commonly occurs in the respiratory tract. Extrapulmonary aspergillosis is usually a part of a disseminated infection, and primary invasive intestinal aspergillosis is very rare. Herein, we report a case of an immunocompetent 53-year-old male who suffered recurrent septic shock in the intensive care unit (ICU) and was finally diagnosed as invasive intestinal aspergillosis without dissemination. IA is rarely considered for patients who do not have an immune disorder. Thus, when such cases do occur, the diagnosis is delayed and the clinical outcome is often poor. However, there is a growing literature reporting IA cases in patients without an immune disorder, mostly among ICU patients. Primary intestinal aspergillosis should be considered for critically ill patients, especially with severe disrupted gastrointestinal mucosal barrier.

Since the Harvard criteria for brain death was proposed in 1968, deceased donor, mainly brain death donor (BD), organ transplantation has been performed worldwide and given the chance for a new life to patients suffering from end-stage organ disease. In Korea by the eager efforts promoting brain-dead organ donation, fortunately, the number of organ donations from the brain-dead has increased successfully in the last decade. However, the disparity between the number of patients awaiting organ transplantation on the list and the number of actual organ donations has become wider and the organ shortage remains a limitation for new lives by transplantation. Because of donor organ restriction, optimal management of brain-dead donors is increasingly important. In addition, the favorable clinical outcomes of recipients is directly associated with the well-preserved organ function of brain-dead donors, which can be accomplished by the maintenance of optimal perfusion. However the brain-dead condition leads to various and profound pathophysiological changes in the neuroendocrine and cardiovascular systems, and management of brain-dead organ donors usually includes active intensive care for maintaining organ function. Therefore, to enhance the potential organ graft function and increase the organ supply, physicians must have knowledge of the pathophysiology of brain death and must deal with rapid hemodynamic changes, endocrine and metabolic abnormalities, and respiratory complications. This article reviews the pathophysiologic changes resulting from brain death and the adequate management for maximizing use of organs recovered from brain death donors.

PURPOSE: To assess the prevalence of multidrug-resistant organisms (MDROs) in inter-hospital transferred critically ill patients. METHODS: This is a retrospective study. The study population comprised patients who were transferred from other hospitals or health care units into the medical or surgical intensive care unit of Samsung Medical Center from January 2012 to December 2014. We evaluated the acquisition of clinically significant MDROs including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococci (VRE), extended-spectrum beta-lactamase (ESBL)-producing Gram-negative bacteria, and carbapenem- resistant Gram-negative bacteria (CRGNB). RESULTS: Three hundred and twenty-one patients were included in this study. One hundred and fifty-one patients (47.0%) had at least one species of MDRO, 21.5% in MRSA, 27.1% in VRE, 15.6% in CRGNB, and 3.7% in ESBL. The prevalence of MDROs was significantly higher in male (52.7%), patients with diabetes (61.6%), patients with combined infectious diseases (51.6%), and medical patients (49.3%). Patients with MRSA had significantly longer length of stay than the patients without MRSA. The patients with CRGNB had higher mortality than the patients without CRGNB. CONCLUSION: The prevalence of MDROs in inter-hospital transferred critically ill patients was very high. Patients with MDROs in this study had longer hospital stay and higher mortality. These patients require more attention for isolation and hygiene protocols, and antibiotic choices.

PURPOSE: Creatine kinase (CK) elevation is caused by rhabdomyolysis, intense exercise, muscle damage, and several drugs. This study evaluated the clinical significance of elevated serum CK levels in patients with an intensive care unit (ICU) and their effects on muscle strength. METHODS: The database of 179 patients, who were examined with CK a t least once among patients in the Samsung Medical Center ICU database, was reviewed retrospectively. Forty-eight patients with a myocardial infarction were excluded and 131 patients were analyzed. The clinical features of patients with an elevated CK of more than 2,000 IU/L (more than 10 times the normal value) and those who did not were compared. RESULTS: The ICU stay days were longer in the high elevation group than the other group (8.6 days vs. 21.7 days, p=0.002). The high elevation group was more likely to go to other treatment centers than home after discharge (14.6% vs. 60.0%, p=0.007). When the Medical Research Council scale was measured, the score of the high elevation group was lower than that of the other group (17.2 vs. 13.3, p=0.006). CONCLUSION: Patients with high CK levels were more likely to receive invasive treatment in the ICU, so their muscle strength may decrease with increasing ICU stay and were less likely to be discharged home because of difficulties in living alone. Therefore, in patients with high CK, anticipating long-term treatment in an ICU, minimizing muscle loss, and maintaining functional muscle strength through active rehabilitation will be helpful for the prognosis of the patient.

Purpose: Intensive IV insulin infusion therapy has been applied widely to critically ill patients. However, IV insulin protocols are complex, and require repeated calculations. The purpose of this study was to evaluate the safety and efficiency of a computerized insulin infusion (CII) protocol to replace manual insulin infusion protocols, for glucose control in critically ill patients. Methods: This was an observational study (September 2016 to January 2017) of 43 patients in ICU whose blood glucose level was between 140-180 mg/mL and could not be controlled by the conventional manual insulin protocol. The CII protocol was integrated in to the electronic medical record order system, and automatically calculated the insulin infusion dose and blood sugar test (BST) interval. BSTs were taken 48 hours pre- and post-initiation of the CII protocol. The proportion of BSTs in the normal (70-180 mg/mL), hypoglycemic (70 mg/mL), and severe hyperglycemic (> 250 mg/mL) range were recorded. Results: The mean number of BSTs performed before using the CII protocol was 10.3/person and 0.4/hour, and after implementing the protocol, increased to 21.7/person and 0.7/hour. The mean glucose level (281.4 mg/mL) decreased after using the CII protocol (195.5 mg/mL; p < 0.001). The percentage of BSTs within normal range increased from 22.5% to 44.9% after implementing the protocol (p < 0.001). Severe hyperglycemia (> 250 mg/mL) decreased from 47.3% to 17.9% after protocol implementation (p = 0.020). Conclusion The CII protocol safely and successfully maintained a normal glucose range, and decreased severe hyperglycemia in intensive care patients.

Purpose: In the intensive care unit, a peripherally inserted central catheter (PICC) may be an alternative option to standard central venous catheters, particularly in patients with coagulopathies or at high risk of infection. The purpose of this research was to assess the feasibility of bedside ultrasound (US)-guided PICC placement by critical care fellows on intensive care units.
Methods: All bedside US-PICCs inserted by critical care fellows from July 2013 to September 2015 were retrospectively reviewed focusing on the rate of successful insertion, complications of insertion, or during maintenance.
Results: A total of 177 US-guided PICCs were inserted in 163 patients and included in the analysis. The median age was 62 years (IQR 50-70 years) and 104 cases (58.8%) were male. There were 172 cases (90.4%) of PICCs inserted in the upper arm. Anticoagulant therapy was used in 26 patients (14.7%) and 8 patients (5.2%) had severe coagulopathies. The median procedural time was 30 minutes (IQR 19-45 minutes). Insertion success rate was 93.2%, and there were no major complications during insertions except for malposition (12.1%). Catheters remained in place for a total of 3,878 days (median 16 days: IQR 8-31 days). There was only 1 case (0.6%) of catheter-related bloodstream infection, and 2 cases (1.2%) of symptomatic venous thromboembolism.
Conclusion Bedside US-guided placement of PICCs by critical care fellows is safe and feasible. The success rate of the procedure was “acceptable,” and was not associated with significant risks of infectious and non-infectious complications, even in patients with coagulopathies.
