AbstractAbstract PDF
Purpose
The purpose of this study was to report the treatment results of patients with traumatic cardiac tamponade after the opening of Jeju Regional Trauma Center.
Methods
We analyzed the treatment outcomes of patients with traumatic cardiac tamponade who were treated at Jeju Regional Trauma Center from January 2018 to August 2022.
Results
Seven patients with traumatic cardiac tamponade were treated. The male to female ratio was 1.33:1 (four male and three female patients) and the average age was 60.3±7.2 years. The mechanism of injury was blunt trauma in six cases and penetrating injury in one case. Upon arrival at the emergency department, pericardiostomy was performed in four cases, and an emergency operation was performed in six cases. Pericardiostomy alone was performed in one patient, who had cardiac tamponade due to extrapericardial suprahepatic inferior vena cava rupture. The causes of cardiac tamponade were right atrium appendage rupture in one case, right ventricle rupture in one case, inferior vena cava rupture in two cases, right atrium and left atrium rupture in one case, both atria and left ventricle rupture in one case, and intercostal artery rupture in one case. In three cases, intraoperative cardiopulmonary bypass was required. Two of the seven patients died (mortality rate, 28.5%).
Conclusions
Relatively favorable treatment results were observed for traumatic cardiac tamponade patients after Jeju Regional Trauma Center was established.

AbstractAbstract PDF
Purpose
There are many studies on the practicality of interleukin-6 (IL-6) as a prognostic predictor in patients with multiple severe traumas. However, few studies focus on the practicality of IL-6 in patients with chest trauma. So, this study investigated whether IL-6 is effective as a prognostic factor in patients with blunt chest trauma.
Methods
A total of 44 blunt chest trauma patients who visited the regional trauma center from July to December 2021 were included in this retrospective study. Blood IL-6 levels were measured immediately after emergency room admittance (IL-6 E) and 24 hours after trauma (IL-6 24). To determine whether IL-6 levels can predict the clinical course and prognosis of patients with blunt chest trauma, the correlation between IL-6 (IL-6 E and IL-6 24) and the trauma score system, Injury Severity Score, Thoracic Trauma Severity Score, and Pulmonary Contusion Score, intensive care unit (ICU) stay period, and total hospitalization period were analyzed.
Results
IL-6 E showed a good correlation with Injury Severity Score (P=0.505), Thoracic Trauma Severity Score (P=0.597), Pulmonary Contusion Score (P=0.493), ICU stay period (P=0.762), and total hospitalization period (P=0.662). However, IL-6 24 had a relatively low correlation compared to IL-6 E. Therefore, IL-6 E showed useful results for predicting the prognosis of patients with blunt chest trauma.
Conclusions
Early plasma IL-6 levels (IL-6 E) can predict the injury severity of blunt chest trauma, length of ICU stay, and total hospitalization period.

AbstractAbstract PDF
Purpose
Ventilator-associated pneumonia is the most common nosocomial infection in patients with mechanical ventilation. In 2013, the new concept of ventilator- associated events (VAEs) replaced the traditional concept of ventilator-associated pneumonia. We analyzed risk factors for VAE occurrence and in-hospital mortality in trauma patients who received mechanical ventilatory support.
Methods
In this retrospective review, the study population comprised patients admitted to the Jeju Regional Trauma Center from January 2020 to January 2021. Data on demographics, injury characteristics, and clinical findings were collected from medical records. The subjects were categorized into VAE and no-VAE groups according to the Centers for Disease Control and Prevention/National Healthcare Safety Network VAE criteria. We identified risk factors for VAE occurrence and in-hospital mortality.
Results
Among 491 trauma patients admitted to the trauma center, 73 patients who received ventilator care were analyzed. Patients with a chest Abbreviated Injury Scale (AIS) score ≥3 had a 4.7-fold higher VAE rate (odds ratio [OR], 4.73; 95% confidence interval [CI], 1.46–17.9), and those with a glomerular filtration rate (GFR) <75 mL/min/1.73 m2 had 4.1-fold higher odds of VAE occurrence (OR, 4.15; 95% CI, 1.32–14.1) and a nearly 4.2-fold higher risk for in-hospital mortality (OR, 4.19; 95% CI, 1.30–14.3). The median VAE-free duration of patients with chest AIS ≥3 was significantly shorter than that of patients with chest AIS <3 (P=0.013).
Conclusions
Trauma patients with chest AIS ≥3 or GFR <75 mL/min/1.73 m2 on admission should be intensively monitored to detect at-risk patients for VAEs and modify the care plan accordingly. VAEs should be closely monitored to identify infections early and to achieve desirable results. We should also actively consider modalities to shorten mechanical ventilation in patients with chest AIS ≥3 to reduce VAE occurrence.
