Purpose
Helicopter transport with medical teams has been proven to be effective, with improvements in patient survival rates. This study compared and analyzed the clinical characteristics and treatment outcomes of trauma patients transported by doctor helicopters according to whether patients were transferred after a clinical evaluation or without a clinical evaluation.
Methods
This study retrospectively reviewed data from the Korean Trauma Data Bank of trauma patients who arrived at a regional trauma center through doctor helicopters from January 1, 2014, to December 31, 2022. The patients were divided into two groups: doctor helicopter transport before evaluation (DHTBE) and doctor helicopter transport after evaluation (DHTAE). These groups were compared.
Results
The study population included 351 cases. At the time of arrival at the trauma center, the systolic blood pressure was significantly lower in the DHTAE group than in the DHTBE group (P=0.018). The Injury Severity Score was significantly higher in the DHTAE group (P<0.001), and the accident to trauma center arrival time was significantly shorter in the DHTBE group (P<0.001). Mortality did not show a statistically significant between-group difference (P=0.094). Surgical cases in the DHTAE group had a longer time from the accident scene to trauma center arrival (P=0.002). The time from the accident to the operation room or from the accident to angioembolization showed no statistically significant differences.
Conclusions
DHTAE was associated with significantly longer transport times to the trauma center, as well as non-statistically significant trends for delays in receiving surgery and procedures, as well as higher mortality. If severe trauma is suspected, air transport to a trauma center should be requested immediately after a simple screening test (e.g., mechanism of injury, Glasgow Coma Scale, or Focused Assessment with Sonography in Trauma), which may help reduce the time to definitive treatment.

AbstractAbstract PDF
A Morel-Lavallée lesion (MLL) is a pathologic fluid collection within an abnormally formed space, resulting from an internal degloving injury between the muscle fascia and subcutaneous fat layer. Due to its resistance to conservative treatments such as drainage or compression dressing, various therapeutic methods have been developed for MLL. However, no standardized guidelines currently exist. Recently, endoscopic debridement and cutaneo-fascial suture (EDCS) has been introduced for the treatment of MLL, particularly for large lesions resistant to conservative approaches. While this procedure is known to be effective, limited reports are available on potential complications. The authors present a case of skin necrosis following EDCS for a massive MLL.

AbstractAbstract PDF
Purpose

Blunt cardiac injuries (BCI) have a wide clinical spectrum, ranging from asymptomatic myocardial contusion to cardiac rupture and death. BCIs rarely require surgical intervention, but can be rapidly fatal, requiring prompt evaluation and surgical treatment in some cases. The aim of this study was to identify potential factors associated with in-hospital mortality after surgery in patients with BCI.

Methods

The medical records of 15 patients who had undergone emergency cardiac surgery for BCI between January 2014 and August 2020 were retrospectively reviewed. We included trauma patients older than 18 years admitted to Regional Trauma Center, Gachon University Gil Medical Center during the study period. Clinical and laboratory variables were compared between survivors and non-survivors.

Results

Non-survivors showed a significantly higher Injury Severity Score (p=0.001) and Abbreviated Injury Scale in the chest region (p=0.001) than survivors. American Association for the Surgery of Trauma-Organ Injury Scale Grade V injuries were significantly more common in non-survivors than in survivors (p=0.031). Non-survivors had significantly more preoperative packed red blood cell (PRBC) transfusions (p=0.019) and were significantly more likely to experience preoperative cardiac arrest (p=0.001) than survivors. Initial pH (p=0.010), lactate (p=0.026), and base excess (BE; p=0.026) levels showed significant differences between the two groups.

Conclusions

Initial pH, lactate, BE, ventricular injury, the amount of preoperative PRBC transfusions, and preoperative cardiac arrest were potential predictors of in-hospital mortality.

AbstractAbstract PDF
Purpose

Immediate post-laparotomy hypotension (PLH) is a precipitous drop in blood pressure caused by a sudden release of abdominal tamponade after laparotomy in cases of severe hemoperitoneum. The effect of laparotomy on blood pressure in patients with significant hemoperitoneum is unknown.

Methods

In total, 163 patients underwent laparotomy for trauma from January 1, 2013 to December 31, 2015. Exclusion criteria included the following: negative laparotomy, only a hollow viscous injury, and hemoperitoneum <1,000 mL. After applying those criteria, 62 patients were enrolled in this retrospective review. PLH was defined as a decrease in the mean arterial pressure (MAP) ≥10 mmHg within 10 minutes after laparotomy.

Results

The mean estimated hemoperitoneum was 3,516 mL. The incidence of PLH was 23% (14 of 62 patients). The MAP did not show significant differences before and after laparotomy (5 minutes post-laparotomy, 67.5±16.5 vs. 68.3±18.8 mmHg; p=0.7; 10 minutes post-laparotomy, 67.5±16.5 vs. 70.4±18.8 mmHg; p=0.193). The overall in-hospital mortality was 24% (15 of 62 patients). Mortality was not significantly higher in the PLH group (two of 14 [14.3%] vs. 13 of 48 [27.1%]; p=0.33). No statistically significant between-group differences were observed in the intensive care unit and hospital stay.

Conclusions

PLH may be less frequent and less devastating than it is often considered. Surgical hemostasis during laparotomy is important. Laparotomy with adequate resuscitation may explain the equivalent outcomes in the two groups.

Summary

AbstractAbstract PDF
Purpose

Accurate and appropriate prehospital field triage is essential for a trauma system. The Korean trauma system (established in 2014) uses the trauma field triage algorithm of the United States Centers for Disease Control and Prevention (CDC). This study evaluated the suitability of the CDC field triage criteria for major trauma cases (injury severity score >15) in Korea.

Methods

This retrospective cohort study evaluated trauma patients who presented at the authors’ regional trauma center from January 1 to May 7, 2017. The undertriage and overtriage rates of each CDC field triage step were calculated. Receiver operating characteristic curves were constructed, and the area under the curve (AUC) was evaluated for each step.

Results

Among the 1,009 enrolled patients, 168 (16.7%) had major trauma. The undertriage/overtriage rates of each step (steps I, II, III, and IV) of CDC field triage were 9.2%/47.4%, 6.3%/50.8%, 4.5%/59.4%, and 5.3%/78.9%, respectively. The AUC values of each CDC triage step were 0.722, 0.783, 0.791, and 0.615, respectively. The AUC values of the separate components of each step (physiologic criteria, anatomic criteria, mechanism-of-injury criteria, and special considerations) were 0.722, 0.648, 0.647, and 0.456, respectively.

Conclusions

The CDC field triage system is acceptable, but not ideal, for Korean trauma care. If we follow the protocol, it would be preferable to omit step IV. The Korean Triage and Acuity Scale may be a good indicator for in-hospital triage. However, a new triage protocol that is simple to estimate on-scene while having good performance should be developed.

AbstractAbstract PDF
Purpose

This study was conducted to investigate the usefulness of a polyester urethane dural substitute (Neuro-Patch®, B. Braun, Boulogne, France) as an anti-adhesion agent in subsequent cranioplasty by analyzing the use of Neuro-Patch® during decompressive craniectomy in traumatic brain injury patients.

Methods

We retrospectively analyzed patients with traumatic brain injury who underwent decompressive craniectomy followed by cranioplasty from January 2015 to December 2018. Patients were analyzed according to whether they received treatment with Neuro-Patch® or not (Neuro-Patch® group, n=71; control group, n=55). Patients’ baseline characteristics were analyzed to identify factors that could affect cranioplasty results, including age, sex, hypertension, diabetes mellitus, use of antiplatelet agents or anticoagulant medication, the interval between craniectomy and cranioplasty, and the type of bone used in cranioplasty. The cranioplasty results were analyzed according to the following factors: operation time, blood loss, postoperative hospitalization period, surgical site infection, and revision surgery due to extra-axial hematoma.

Results

No significant difference was found between the two groups regarding patients’ baseline characteristics. For the cranioplasty procedures, the operation time (155 vs. 190 minutes, p=0.003), intraoperative blood loss (350 vs. 450 mL, p=0.012), and number of surgical site infections (4 vs. 11 cases, p=0.024) were significantly lower in the Neuro-Patch® group than in the control group.

Conclusions

The use of Neuro-Patch® was associated with a shorter operation time, less blood loss, and a lower number of surgical site infections in subsequent cranioplasties. These results may provide a rationale for prospective studies investigating the efficacy of Neuro-Patch®.

AbstractAbstract PDF
Purpose

Blunt injury accounts for 80?95% of renal injury trauma in the United States. The majority of blunt renal injuries are low grade and 80?85% of these injuries can be managed conservatively. However, there is a debate on the management of patients with high-grade renal injury. We reviewed our experience of renal trauma at our trauma center to assess management strategy for high-grade blunt renal injury.

Methods

We reviewed blunt renal injury cases admitted at a single trauma center between August 2007 and December 2015. Computed tomography (CT) scan was used to diagnose renal injuries and high?grade (according to the American Association for the Surgery of Trauma [AAST] organ injury scale III?V) renal injury patients were included in the analysis.

Results

During the eight?year study period, there were 62 AAST grade III?V patients. 5 cases underwent nephrectomy and 57 underwent non-operative management (NOM). There was no difference in outcome between the operative group and the NOM group. In the NOM group, 24 cases underwent angioembolization with a 91% success rate. The Incidence of urological complications correlated with increasing grade.

Conclusions

Conservative management of high-grade blunt renal injury was considered preferable to operative management, with an increased renal salvage rate. However, high-grade injuries have higher complication rates, and therefore, close observation is recommended after conservative management.

AbstractAbstract PDF
PURPOSE
Bleeding is the primary cause of death after severe pelvic fracture. Transcatheter arterial embolization (TAE) is the mainstay of treatment for arterial bleeding. This study aimed to determine the frequency of bleeding by angiography of blush-positive pelvic fractures on computed tomography (CT) images. The bleeding arteries that were involved were investigated by pelvic angiography.
METHODS
This retrospective cohort study evaluated 83 pelvic fracture patients who were treated in the intensive care unit of the author's trauma center between January 01, 2013 and April 30, 2015.
RESULTS
Overall mortality was 9 of 83 patients (10.8%). Blush was observed in 37 patients; blush-positive patients had significantly higher mortality (24.3%) than blush-negative patients (0%). Twenty-four of the 83 patients (28.9%) underwent pelvic angiography. Bleeding was showed in 22 of 24 patients in pelvic angiography. TAE was successfully performed in 21 (95.5%) of the bleeding 22 patients. Angiography was performed in 23 of 37 blush-positive patients, and arterial bleeding was identified in 21 (91.3%). A total 33 bleeding arteries were identified in 22 angiography-positive patients. The most frequent origin of bleeding was internal iliac artery (69.7%) followed by the external iliac artery (18.2%) and lumbar arteries (12.1%).
CONCLUSION
The vascular blush observed in CT scans indicates sites of ongoing bleeding in pelvic angiography. TAE is an excellent therapeutic option for arterial bleeding and has a high success rate with few complications.
