BACKGROUND: Unplanned extubation (UE) of patients requiring mechanical ventilation in an intensive care unit (ICU) is associated with poor outcomes for patients and organizations. This study was conducted to assess the clinical features of patients who experienced UE and to determine the risk factors affecting reintubation after UE in an ICU. METHODS: Among all adult patients admitted to the ICU in our institution who required mechanical ventilation between January 2011 and December 2013, those in whom UE was noted were included in the study. Data were categorized according to noninvasive or invasive management after UE. RESULTS: The rate of UE was 0.78% (the number of UEs per 100 days of mechanical ventilation). The incidence of self-extubation was 97.2%, while extubation was accidental in the remaining patients. Two cases of cardiac arrest combined with respiratory arrest after UE were noted. Of the 214 incidents, 54.7% required invasive management after UE. Long duration of mechanical ventilation (odds ratio [OR] 1.52; 95% confidence interval [CI] 1.32-1.75; p = 0.000) and high ICU mortality (OR 4.39; 95% CI 1.33-14.50; p = 0.015) showed the most significant association with invasive management after UE. In multivariate analysis, younger age (OR 0.96; 95% CI 0.93-0.99; p = 0.005), medical patients (OR 4.36; 95% CI 1.95-9.75; p = 0.000), use of sedative medication (OR 4.95; 95% CI 1.97-12.41; p = 0.001), large amount of secretion (OR 2.66; 95% CI 1.01-7.02; p = 0.049), and low PaO2/FiO2 ratio (OR 0.99; 95% CI 0.98-0.99; p = 0.000) were independent risk factors of invasive management after UE. CONCLUSIONS: To prevent unfavorable clinical outcomes, close attention and proper ventilatory support are required for patients with risk factors who require invasive management after UE.

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.

Conventional medical therapies have not been very successful in treating adults with refractory septic shock. The effects of direct hemoperfusion using polymyxin B and veno-arterial extracorporeal membrane oxygenation (ECMO) for refractory septic shock remain uncertain. A 66-year-old man was admitted to the emergency department and suffered from sepsis-induced hemodynamic collapse. For hemodynamic improvement, we performed direct hemoperfusion using polymyxin B. Computed tomography scan of this patient revealed emphysematous pyelonephritis (EPN), for which he underwent emergent nephrectomy with veno-arterial ECMO support. To the best of our knowledge, this is the first report of successful treatment of EPN with refractory septic shock using polymyxin B hemoperfusion and nephrectomy under the support of ECMO.

Mucormycosis is an uncommon opportunistic fungal infection mostly affecting immunocompromised patients and gastrointestinal mucormycosis is a rare and life-threatening. We describe a 31-year-old man with a history of idiopathic cyclic neutropenia who developed perforations of the stomach and intestine and intra-abdominal bleeding due to disseminated gastrointestinal mucormycosis after the initial operation.

Although shock in sepsis is usually managed successfully by conventional medical treatment, a subset of cases do not respond and may require salvage therapies such as veno-arterial extracorporeal membrane oxygenation (VA ECMO) support as well as an attempt to remove endotoxins. However, there are limited reports of attempts to remove endotoxins in patients with septic shock on VA ECMO support. We recently experienced a case of septic shock with severe myocardial injury whose hemodynamic improvement was unsatisfactory despite extracorporeal membrane oxygenation (ECMO) support. Since the cause of sepsis was acute pyelonephritis and blood cultures grew gram-negative bacilli, we additionally applied polymyxin B direct hemoperfusion (PMX-DHP) to the ECMO circuit and were able to successfully taper off vasopressors and wean off ECMO support. To the best of our knowledge, this is the first adult case in which PMX-DHP in addition to ECMO support was successfully utilized in a patient with septic shock. This case indicates that additional PMX-DHP therapy may be beneficial and technically feasible in patients with septic shock with severe myocardial injury refractory to ECMO support.

BACKGROUND: Colistin (polymyxin E) is active against multidrug-resistant Gram-negative bacteria (MDR-GNB). However, the effectiveness of inhaled colistin is unclear. This study was designed to assess the effectiveness and safety of aerosolized colistin for the treatment of ventilator-associated pneumonia (VAP) caused by MDR-GNB. METHODS: In this retrospective longitudinal study, we evaluated the medical records of 63 patients who received aerosolized colistin treatment for VAP caused by MDR-GNB in the medical intensive care unit (MICU) from February 2012 to March 2014. RESULTS: A total of 25 patients with VAP caused by MDR-GNB were included in this study. The negative conversion rate was 84.6% after treatment, and acute kidney injury (AKI) occurred in 11 patients (44%, AKI group). The average length of MICU stay and colistin treatment- related factors, such as daily and total cumulative doses and administration period, were not significantly different between groups. In-hospital mortality tended to be higher in the AKI group (p = 0.07). Multivariate analysis showed that a body mass index less than 18 was an independent risk factor of mortality (odds ratio [OR] = 21.95, 95% confidence interval [CI] 1.59-302.23; p = 0.02). Notably, AKI occurrence was closely related to the administration of more than two nephrotoxic drugs combined with aerosolized colistin (OR = 15.03, 95% CI 1.40-161.76; p = 0.025) and septic shock (OR = 8.10, 95% CI 1.40-161.76; p = 0.04). CONCLUSIONS: The use of adjunctive aerosolized colistin treatment appears to be a relatively safe and effective option for the treatment of VAP caused by MDR-GNB. However, more research on the concomitant use of nephrotoxic drugs with aerosolized colistin will be necessary, as this can be an important risk factor of development of AKI.

Limited data are available on improved outcomes after initiation of neurointensivist co-management in neurosurgical intensive care units (NSICUs) in Korea. We evaluated the impact of a newly appointed neurointensivist on the outcomes of neurosurgical patients admitted to an intensive care unit (ICU). This retrospective observational study involved neurosurgical patients admitted to the NSICU at Samsung Medical Center between March 2013 and May 2016. Neurointensivist co-management was initiated in October 1 2014. We compared the outcomes of neurosurgical patients before and after neurointensivist co-management. The primary outcome was ICU mortality. A total of 571 patients were admitted to the NSICU during the study period, 291 prior to the initiation of neurointensivist co-management and 280 thereafter. Intracranial hemorrhage (29.6%) and traumatic brain injury (TBI) (26.6%) were the most frequent reasons for ICU admission. TBI was the most common cause of death (39.0%). There were no significant differences in mortality rates and length of ICU stay before and after co-management. However, the rates of ICU and 30-day mortality among the TBI patients were significantly lower after compared to before initiation of neurointensivist co-management (8.5% vs. 22.9%; P = 0.014 and 11.0% vs. 27.1%; P = 0.010, respectively). Although overall outcomes were not different after neurointensivist co-management, initiation of a strategy of routine involvement of a neurointensivist significantly reduced the ICU and 30-day mortality rates of TBI patients.
