Purpose
Traumatic brain injury (TBI) directly affects the survival of patients and can cause long-term sequelae. The purpose of our study was to investigate whether the operation of a trauma center in a single tertiary general hospital has improved emergency care and clinical outcomes for patients with TBI.
Methods
The participants of this study were all TBI patients, patients with isolated TBI, and patients with TBI who underwent surgery within 24 hours, who visited our level 1 trauma center from March 1, 2012 to February 28, 2020. Patients were divided into two groups: patients who visited before and after the operation of the trauma center. A comparative analysis was conducted. Differences in detailed emergency care time, hospital stay, and clinical outcomes were investigated in this study.
Results
On comparing the entire TBI patient population via dividing them into the aforementioned two groups, the following results were found in the group of patients who visited the hospital after the operation of the trauma center: an increased number of patients with a good functional prognosis (P<0.001 and P=0.002, respectively), an increased number of surviving discharges (P<0.001 and P<0.001, respectively), and a reduction in overall emergency care time (P<0.05, for all item values). However, no significant differences existed in the length of intensive care unit stay, ventilator days, and total length of stay for TBI patients who visited the hospital before and after the operation of the trauma center.
Conclusions
The findings confirmed that overall TBI patients and patients with isolated brain injury had improved treatment results and emergency care through the operation of a trauma center in a tertiary general hospital.

AbstractAbstract PDF
Purpose

Hemorrhagic shock is the leading cause of death in trauma patients worldwide. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a technique used to improve the hemodynamic stability of patients with traumatic shock and to temporarily control arterial hemorrhage. However, further research is required to determine whether REBOA with cardiopulmonary resuscitation (CPR) in near-arrest or arrest trauma patients can help resuscitation. We analyzed trauma patients who underwent REBOA according to their CPR status and evaluated the effects of REBOA in arrest situations.

Methods

This study was a retrospective single-regional trauma center study conducted at a tertiary medical institution from February 2017 to November 2019. We evaluated the mortality of severely injured patients who underwent REBOA and analyzed the factors that influenced the outcome. Patients were divided into CPR and non-CPR groups.

Results

We reviewed 1,596 trauma patients with shock, of whom 23 patients underwent REBOA (1.4%). Two patients were excluded due to failure and a repeated attempt of REBOA. The Glasgow Coma Scale score was lower in the CPR group than in the non-CPR group (p=0.009). Blood pressure readings at the emergency room were lower in the CPR group than in the non-CPR group, including systolic blood pressure (p=0.012), diastolic blood pressure (p=0.002), and mean arterial pressure (p=0.008). In addition, the mortality rate was higher in the CPR group (100%) than in the non-CPR group (50%) (p=0.012). The overall mortality rate was 76.2%.

Conclusions

Our study suggests that if REBOA is deemed necessary in a timely manner, it is better to perform REBOA before an arrest occurs. Therefore, appropriate protocols, including pre-hospital REBOA, should be constructed to demonstrate the effectiveness of REBOA in reducing mortality in arrest or impending arrest patients.

Purpose

Trauma systems have been shown to decrease injury-related mortality. The present study aimed to compare the mortality rates of patients with major trauma (injury severity score >15) treated before and after the establishment of a level I trauma center.

Methods

During this 20-month study, participants were divided into pre-trauma center and trauma center groups, and trauma and injury severity score (TRISS) method was used to compare mortality rates during 10-month periods before and after the establishment of the trauma center (October 2013 to July 2014 vs. October 2014 to July 2015).

Results

Of the 541 total participants, 278 (51.5%) visited after the establishment of the trauma center. The Z and W statistics indicated better outcomes in the trauma center group than in the pre-trauma center group (Z statistic, 2.635 vs. ?0.700; W statistic, 4.640). The trauma center group also exhibited meaningful reductions in the time interval from the emergency department (ED) visit to emergency surgery (118.0 minutes vs. 142.5 minutes, p=0.020) and the interval from the ED visit to intensive care unit admission (202.0 minutes vs. 259.0 minutes, p=0.035) relative to the pre-trauma center group.

Conclusions

The TRISS and multivariate analysis revealed significant improvements in survival rates in the trauma center group, compared to the pre-trauma center group.

AbstractAbstract PDF
PURPOSE
S100beta, a marker of traumatic brain injury (TBI), has been increasingly focused upon during recent years. S100beta, is easily measured not only in cerebrospinal fluid (CSF) but also in serum. After TBI, serum S100beta, has been found to be increased at an early stage. The purpose of this study was to evaluate the clinical correlations between serum S100beta, and neurologic outcome, and severity in traumatic brain injury.
METHODS
From August 2006 to October 2006, we made a protocol and studied prospectively 42 patients who visited the emergency room with TBI. Venous blood samples for S100beta, protein were taken within six hours after TBI and vital signs, as well as the Glasgow Coma Scale (GCS), were recorded. The final diagnosis and the severity were evaluated using the Abbreviated Injury Score (AIS), and the prognosis of the patients was evaluated using the Glasgow Outcome Score (GOS).
RESULTS
Thirty-eight patients showed a favorable prognosis (discharge, recovery, transfer), and four showed an unfavorable prognosis. Serum S100beta, was higher in patients with an unfavorable prognosis than in patients with a favorable prognosis, and a significant difference existed between the two groups (0.74+/-50 microgram/L vs 7.62+/-6.53 microgram/L P=0.002). A negative correlation existed between serum S100beta, and the Revised Traumatic Score (R2=-0.34, P=0.03), and a positive correlation existed between serum S100beta, and the Injury Severity Score (R2=0.33, P=0.03). Furthermore, the correlations between serum S100beta, and the initial GCS and the GCS 24 hours after admission to the ER were negative (R2=-0.62, P<0.001; R2=-0.47, P=0.005). Regarding the GOS, the mean serum concentration of S100beta. was 7.62 beta partial differential/L (SD=+/-6.53) in the expired patients, 1.15 microgram/L in the mildly disable patient, and 0.727 microgram/L (SD=+/-0.73) in the recovered patients. These differences are statistically significant (p<0.001).
CONCLUSION
In traumatic brain injury, a higher level of serum concentration of S100beta, has a poor prognosis for neurologic outcome.
