Abstract The objective of this study was to evaluate the prognostic value C-reactive protein (CRP), procalcitonin (PCT), and their combination for mortality in patients with septic shock. This multicenter, prospective, observational conducted between November 2015 December 2017. A total 1,772 shock were included, overall 28-day 20.7%. Although both CRP PCT elevated non-survivor group, only had statistical significance (11.9 mg/dL vs. 14.7 mg/dL, p = 0.003, 6.4 ng/mL 8.2 ng/mL, 0.508)....

The Sepsis-3 criteria introduced the system that uses Sequential Organ-Failure Assessment (SOFA) score to define sepsis. cardiovascular SOFA (CV SOFA) scoring needs modification due change in guideline-recommended vasopressors. In this study, we aimed develop and validate modified CV score.We developed, internally validated, externally validated using suspected infection cohort, sepsis septic shock cohort. primary outcome was 28-day mortality. constructed with consideration of recently...

Abstract Rapid response teams have been adopted to prevent unexpected in-ward cardiac arrest. However, there is no convincing evidence of optimal operation with rapid team. Our aim was address the impact focused team on safety patients in wards. Comparison extended performed single center. The operated adult whole ward (both medical and nonmedical ward) 24 hours per day, 7 days week during 2012. In 2015, operational time office from Monday Friday study population were limited ward....

Septic shock can be defined both by the presence of hyperlactatemia and need vasopressors. Lactate levels should measured after volume resuscitation (as per Sepsis-3 definition). However, currently, no studies have evaluated patients who been excluded new criteria for septic shock. The aim this study was to determine clinical characteristics prognosis these patients, based on their lactate initial fluid resuscitation. This observational performed using a prospective, multi-center registry...

Background This study aimed to investigate the relationship between body mass index (BMI) and sufficient chest compression depth (CCD) in obese patients by a mathematical model. Methods Results retrospective analysis was performed with computed tomography images conducted 2006 2018. We classified selected individuals into underweight (<18.5), normal weight (≥18.5, <25), overweight (≥25, <30), (≥30) groups according BMI (kg/m2). defined heart fraction (HCF) as [Formula: see text] estimated...

Out-of-hospital cardiac arrest (OHCA) is a major public health problem and leading cause of death worldwide. Previous studies have focused on improving the survival people who had OHCA by analyzing short-term outcomes, such as return spontaneous circulation, 30-day survival, to discharge. Research has been conducted prehospital prognostic factors improve patients with OHCA, among which association between socioeconomic status (SES) reported. SES could affect bystander cardiopulmonary...

Epidural analgesia has become a common procedure to provide excellent pain relief with few complications. Pneumorrhachis and pneumocephalus are rare complications of unintentional dural puncture injection air into the subarachnoid or subdural space. No cases cardiac arrest associated these have been reported in literature previously. We report pneumorrhachis two Korean women who previously visited local clinic underwent epidural analgesia. Thereafter, they were admitted emergency department...
