研究室紹介
Professor Ikjun Cho's research lab specializes in critical care medicine, with a primary focus on improving outcomes in severe critical illnesses such as sepsis, septic shock, and cardiac arrest. The lab investigates prognostic biomarkers—particularly lactate, albumin, CRP, and procalcitonin—to predict mortality and guide early intervention. It also examines the impact of systemic factors like emergency department crowding and advanced resuscitation techniques such as extracorporeal cardiopulmonary resuscitation on patient survival and neurological outcomes. The research emphasizes evidence-based, early resuscitation strategies aligned with international guidelines.

15OBJECTIVE: We investigated whether the survival of patients with inhospital cardiac arrest could be extended by extracorporeal cardiopulmonary resuscitation supported with extracorporeal membrane oxygenation compared with those of conventional cardiopulmonary resuscitation. DESIGN: : A retrospective, single-center, observational study. SETTING: A tertiary care university hospital. PATIENTS: We retrospectively analyzed a total of 406 adult patients with witnessed inhospital cardiac arrest receivi
AIM: The aim of this study was to evaluate the clinical utility of the lactate/albumin (L/A) ratio as a predictive factor of 28-day mortality in critically ill sepsis patients. METHODS: This is a retrospective observational study from a prospectively collected multicenter registry of 10 emergency departments (EDs) in teaching hospitals that participated in the Korean Shock Society. It enrolled patients who were 19 years of age or older who had a suspected or confirmed infection and evidence of r
The objective of this study was to evaluate the prognostic value of C-reactive protein (CRP), procalcitonin (PCT), and their combination for mortality in patients with septic shock. This multicenter, prospective, observational study was conducted between November 2015 and December 2017. A total of 1,772 septic shock patients were included, and the overall 28-day mortality was 20.7%. Although both CRP and PCT were elevated in the non-survivor group, only CRP had statistical significance (11.9 mg/
INTRODUCTION: The aim of this study is to evaluate the effects of emergency department (ED) crowding on the implementation of tasks in the early resuscitation bundle during acute care of patients with severe sepsis and septic shock, as recommended by the Surviving Sepsis Campaign guidelines. METHODS: We analyzed the sepsis registry from August 2008 to March 2012 for patients presenting to an ED of a tertiary urban hospital and meeting the criteria for severe sepsis or septic shock. The ED occupa
INTRODUCTION: Several methods have been proposed to evaluate neurological outcome in out-of-hospital cardiac arrest (OHCA) patients. Blood lactate has been recognized as a reliable prognostic marker for trauma, sepsis, or cardiac arrest. The objective of this study was to examine the association between initial lactate level or lactate clearance and neurologic outcome in OHCA survivors who were treated with therapeutic hypothermia. METHODS: This retrospective cohort study included patients who u

Lactate levels in metformin users were initially elevated in the early phase of resuscitation from severe sepsis and septic shock. However, there was no significant difference in lactate levels, LC, and normalization over the initial 24 h period based on metformin use.
Oxygenation category, as represented by initial Scvo2 and lactate levels, was significantly associated with 28-day mortality in patients with severe sepsis or septic shock. Associations between Scvo2 ≥70% and 28-day survival were observed only in patients without severe lactic acidosis.
