Abstract PDF Supplementary Material: Background
The effectiveness of intravenous tissue plasminogen activator (IV tPA) in patients with large-vessel occlusion (LVO) receiving endovascular treatment (EVT) for acute ischemic stroke (AIS) has been questioned. We investigated IV tPA effectiveness in real-world AIS patients, including those with intracranial LVO receiving EVT.
Methods
We identified patients with AIS who presented to hospital with National Institutes of Health Stroke Scale ≥4 within 8 hours of symptom onset from the institutional stroke registry. The association of IV tPA use with effectiveness and safety outcomes was analyzed in overall enrolled AIS patients; LVO patients; and patients treated with EVT. The effect of IV tPA was assessed using multiple logistic regression.
Results
Among the 654 patients meeting study entry criteria, 238 (36.4%) received IV tPA and 416 (63.6%) did not. Multiple logistic regression analysis and shift analysis revealed IV tPA was associated with improved outcomes in overall enrolled AIS population, LVO, and EVT-treated subgroups. Among EVT-treated patients, IV tPA was associated with higher likelihood of ambulatory or better outcome (modified Rankin Scale 0–3) with odds ratio of 1.95 (P=0.03).
Conclusions
In this real-world study, IV tPA use was associated with improved outcomes for patients with AIS, including among LVO patients treated and not treated with EVT, in the contemporary mechanical thrombectomy era.

Background
Despite recent advances and global improvements in sepsis recognition and supportive care, mortality rates remain high, and adherence to sepsis bundle components in Korea is low. To address this, the Korean Sepsis Alliance, affiliated with the Korean Society of Critical Care Medicine, developed the first sepsis treatment guidelines for Korea based on a comprehensive systematic review and meta-analysis.
Methods
A de novo method was used to develop the guidelines. Methodologies included determining key questions, conducting a literature search and selection, assessing the risk of bias, synthesizing evidence, and developing recommendations. The certainty of evidence and the strength of recommendations were determined using the Grading of Recommendations, Assessment, Development, and Evaluations approach. Draft recommendations underwent internal and external review processes and public hearings. The development of these guidelines was supported by a research grant from the Korean Disease Control and Prevention Agency.
Results
In these guidelines, we focused on early treatments for adult patients with sepsis and septic shock. Through the guideline development process, 12 key questions and their respective recommendations were formulated. These include lactate measurement, fluid therapies, target blood pressure, antibiotic administration, use of vasopressors and dobutamine, extracorporeal membrane oxygenation, and echocardiography.
Conclusions
These guidelines aim to support medical professionals in making appropriate decisions about treating adult sepsis and septic shock. We hope these guidelines will increase awareness of sepsis and reduce its mortality rate.

Background
Successful liberation from mechanical ventilation is one of the most crucial processes in critical care because it is the first step by which a respiratory failure patient begins to transition out of the intensive care unit and return to their own life. Therefore, when devising appropriate strategies for removing mechanical ventilation, it is essential to consider not only the individual experiences of healthcare professionals, but also scientific and systematic approaches. Recently, numerous studies have investigated methods and tools for identifying when mechanically ventilated patients are ready to breathe on their own. The Korean Society of Critical Care Medicine therefore provides these recommendations to clinicians about liberation from the ventilator.
Methods
Meta-analyses and comprehensive syntheses were used to thoroughly review, compile, and summarize the complete body of relevant evidence. All studies were meticulously assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) method, and the outcomes were presented succinctly as evidence profiles. Those evidence syntheses were discussed by a multidisciplinary committee of experts in mechanical ventilation, who then developed and approved recommendations.
Results
Recommendations for nine PICO (population, intervention, comparator, and outcome) questions about ventilator liberation are presented in this document. This guideline includes seven conditional recommendations, one expert consensus recommendation, and one conditional deferred recommendation.
Conclusions
We developed these clinical guidelines for mechanical ventilation liberation to provide meaningful recommendations. These guidelines reflect the best treatment for patients seeking liberation from mechanical ventilation.

Abstract PDF Supplementary Material

Background
Mechanical power (MP) has been reported to be associated with clinical outcomes. Because the original MP equation is derived from paralyzed patients under volume-controlled ventilation, its application in practice could be limited in patients receiving pressure-controlled ventilation (PCV). Recently, a simplified equation for patients under PCV was developed. We investigated the association between MP and intensive care unit (ICU) mortality.
Methods
We conducted a retrospective analysis of Korean data from the Fourth International Study of Mechanical Ventilation. We extracted data of patients under PCV on day 1 and calculated MP using the following simplified equation: MPPCV = 0.098 ∙ respiratory rate ∙ tidal volume ∙ (ΔPinsp + positive end-expiratory pressure), where ΔPinsp is the change in airway pressure during inspiration. Patients were divided into survivors and non-survivors and then compared. Multivariable logistic regression was performed to determine association between MPPCV and ICU mortality. The interaction of MPPCV and use of neuromuscular blocking agent (NMBA) was also analyzed.
Results
A total of 125 patients was eligible for final analysis, of whom 38 died in the ICU. MPPCV was higher in non-survivors (17.6 vs. 26.3 J/min, P<0.001). In logistic regression analysis, only MPPCV was significantly associated with ICU mortality (odds ratio, 1.090; 95% confidence interval, 1.029–1.155; P=0.003). There was no significant effect of the interaction between MPPCV and use of NMBA on ICU mortality (P=0.579).
Conclusions
MPPCV is associated with ICU mortality in patients mechanically ventilated with PCV mode, regardless of NMBA use.

Abstract PDF

Background
Evidence for using high-flow nasal cannula (HFNC) in hypercapnia is still limited. Most of the clinical studies had been conducted retrospectively, and there had been conflicting reports for the effects of HFNC on hypercapnia correction in prospective studies. Therefore, more evidence is needed to understand the effect of the HFNC in hypercapnia.
Methods
We conducted a multicenter prospective observational study after applying HFNC to 45 hospitalized subjects who had moderate hypercapnia (arterial partial pressure of carbon dioxide [PaCO2], 43–70 mm Hg) without severe respiratory acidosis (pH <7.30). The primary outcome was a change in PaCO2 level in the first 24 hours of HFNC use. The secondary outcomes were changes in other parameters of arterial blood gas analysis, changes in respiration rates, and clinical outcomes.
Results
There was a significant decrease in PaCO2 in the first hour of HFNC application (-3.80 mm Hg; 95% confidence interval, -6.35 to -1.24; P<0.001). Reduction of PaCO2 was more prominent in subjects who did not have underlying obstructive lung disease. There was a correction in pH, but no significant changes in respiratory rate, bicarbonate, and arterial partial pressure of oxygen/fraction of inspired oxygen ratio. Mechanical ventilation was not required for 93.3% (42/45) of our study population.
Conclusions
We suggest that HFNC could be a safe alternative for oxygen delivery in hypercapnia patients who do not need immediate mechanical ventilation. With HFNC oxygenation, correction of hypercapnia could be expected, especially in patients who do not have obstructive lung diseases.

Abstract PDF

Background
Mortality rates associated with sepsis have increased progressively in Korea, but domestic epidemiologic data remain limited. The objective of this study was to investigate the characteristics, management and clinical outcomes of sepsis patients in Korea.
Methods
This study is a multicenter retrospective cohort study. A total of 64,021 adult patients who visited an emergency department (ED) within one of the 19 participating hospitals during a 1-month period were screened for eligibility. Among these, patients diagnosed with sepsis based on the third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) were included in the study.
Results
Using the Sepsis-3 criteria, 977 sepsis patients were identified, among which 36.5% presented with septic shock. The respiratory system (61.8%) was the most common site of infection. The pathogen involved was identified in 444 patients (45.5%) and multi-drug resistance (MDR) pathogens were isolated in 171 patients. Empiric antibiotic therapy was appropriate in 68.6% of patients, but the appropriateness was significantly reduced in infections associated with MDR pathogens as compared with non-MDR pathogens (58.8% vs. 76.0%, P<0.001). Hospital mortality was 43.2% and 18.5% in sepsis patients with and without shock, respectively. Of the 703 patients who survived to discharge, 61.5% were discharged to home and 38.6% were transferred to other hospitals or facilities.
Conclusions
This study found the prevalence of sepsis in adult patients visiting an ED in Korea was 1.5% (15.2/1,000 patients). Patients with sepsis, especially septic shock, had a high mortality and were often referred to step-down centers after acute and critical care.

Abstract PDF

There is no well-stated practical guideline for mechanically ventilated patients with or without acute respiratory distress syndrome (ARDS). We generate strong (1) and weak (2) grade of recommendations based on high (A), moderate (B) and low (C) grade in the quality of evidence. In patients with ARDS, we recommend low tidal volume ventilation (1A) and prone position if it is not contraindicated (1B) to reduce their mortality. However, we did not support high-frequency oscillatory ventilation (1B) and inhaled nitric oxide (1A) as a standard treatment. We also suggest high positive end-expiratory pressure (2B), extracorporeal membrane oxygenation as a rescue therapy (2C), and neuromuscular blockage for 48 hours after starting mechanical ventilation (2B). The application of recruitment maneuver may reduce mortality (2B), however, the use of systemic steroids cannot reduce mortality (2B). In mechanically ventilated patients, we recommend light sedation (1B) and low tidal volume even without ARDS (1B) and suggest lung protective ventilation strategy during the operation to lower the incidence of lung complications including ARDS (2B). Early tracheostomy in mechanically ventilated patients can be performed only in limited patients (2A). In conclusion, of 12 recommendations, nine were in the management of ARDS, and three for mechanically ventilated patients.

Abstract PDF

Infections due to multidrug resistant Acinetobacter baumannii have become a challenging problem in intensive care units. Tigecycline is a derivative of minocyline, and has provided new hope for the treatment of multidrug-resistant A. baumannii infections. Because isolates showing reduced susceptibility to minocycline or tigecycline have emerged in many countries, empirical combination therapy has become common practice to treat patients infected with extreme drug-resistant A. baumannii. Herein we report a case of extreme drug-resistant A. baumannii infection successfully treated with tigecycline and amikacin.

Abstract PDF: BACKGROUND
There are only inadequate studies on the characteristics of severe pneumonia in the patients who have solid cancer and who are treated with cytotoxic chemotherapy and also on the usefulness of the various severity index scores.
METHODS
We retrospectively reviewed 31 patients who were treated with cytotoxic chemotherapy because of solid cancer and who were admitted to the medical ICU at Samsung Medical Center from April 2007 to August 2008.
RESULTS
The median age of the 31 patients was 64 years old (34-79). The types of solid cancer were lung cancer (19, 61.3%), gastroesophageal cancer (4, 12.9%), breast cancer (2, 6.5%), liver cancer (1, 3.2%), ovarian cancer (1, 3.2%) and other types of cancer (4, 12.9%). The hospital mortality rate was 64.5%. We were able to determine the pathogen of 19 (61.3%) patients; S. pneumoniae (6), S. aureus (3), Candida species (3), P. aeruginosa (2), K. pneumoniae (1), Pneumocystis jiroveci (1) and others (3). There were no statistically differences of the laboratory data and severity index scores (PSI, CURB-65, APACHE II, SOFA, SAPS 3) between the survivors and nonsurvivors, except the P/F ratio.
CONCLUSIONS
The hospital mortality rate of severe pneumonia in patients who had solid cancer and who received cytotoxic chemotherapy was high. The major pathogen was S. pneumoniae. The severity indexes for general pneumonia were not useful to these patients.

Abstract PDF: BACKGROUND
Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the leading causes of death after lungresection. Neutrophil elastase is thought to be an important mediator in the pathogenesis of ALI. Sivelestat is a new neutrophil elastase inhibitor which may improve the outcome in patients with ALI/ARDS after lung resection. The objective of this study was to determine whether or not sivelestat can reduce mortality in patients with ALI after pulmonary resection for lung cancer.
METHODS
This study was a retrospective case-control study of twenty three patients who developed ALI/ARDS within seven days of lung resection for lung cancer. The control group (n = 12) received standard care, while the sivelestat group (n = 11) received a continuous infusion of sivelestat (0.2 mg/kg/hr) for seven days in addition to standard care.
RESULTS
There was no significant difference in the baseline characteristics between the control and sivelestat groups, except for heart rate. Six of twelve patients (50%) in the control group survived, while seven of twelve patients (64%) survived in the sivelestat group (p = 0.34). There was also no significant difference between the two groups in the progression to ARDS. In the sivelelestat group, survivors had lower APACHE II and SOFA scores than the patients in the control group.
CONCLUSIONS
There was no additional effect of a neutrophil elastase inhibitor in the treatment of ALI after pulmonary resection for lung cancer.

Abstract PDF

BACKGROUND
The role of glucocorticoids for treating persistent acute respiratory distress syndrome (ARDS) is matter of debate. In the previous studies, the side effects of moderate doses of glucocorticoids might have negated positive effects of glucocorticoids. This study aimed at determining the feasibility of administering "low-dose" glucocorticoid to treat the patients who suffer with persistent ARDS.
METHODS
We retrospectively reviewed the medical records of twelve patients with ARDS of at least seven days' duration and who were treated with "low-dose" glucocorticoid (starting dose of 1 mg/kg) between June 2007 to December 2008. The patients were divided by whether or not they were successfully weaned from the ventilator after glucocorticoid therapy. The baseline characteristics and physiologic parameters were recorded for up to 7 days after starting glucocorticoid therapy.
RESULTS
Five patients (42%) were included in the weaned group. There was no significant difference in the clinical characteristics and the physiologic parameters between the two groups on the day of ARDS. Yet the weaned group had a significantly lower Sequential Organ Failure Assessment (SOFA) score, as compared to that of the failed group [3 (3-6) vs 8 (5-12), p = 0.009)] at start of glucocorticoid treatment. After 3 days of glucocorticoid therapy, there was significant improvement in the PEEP, the PaO2/FIO2 ratio, the PCO2, the SOFA score and the Murray Lung Injury Score of the weaned group, as compared to that of the failed group. There were no major neuromuscular side effects from the therapy.
CONCLUSIONS
This study suggests that the "low-dose" glucocorticoid therapy is feasible and that the SOFA score and the physiologic parameters may assist in determining whether or not to initiate and to continue glucocorticoid therapy for the patients who are suffering with persistent ARDS.
