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.

AbstractAbstract PDF

Although hemothorax and pneumothorax are common complications seen in rib fractures, focal extrapleural hematoma is quite rare. We report a 63-year-old female patient that developed large focal extrapleural hematoma after falling off a second floor veranda. The patient had sustained 3, 4, 5th costal cartilage rib fractures and a sternum fracture. She had developed suspected empyema with loculations with small amount of hemothorax. She underwent a planned early decortication/adhesiolysis by video assisted thoracoscopic surgery at the 12th post-trauma day due to failed drainage. Unexpectedly, she had no adhesions or any significant retained hematoma mimicking a mass, but was found with the focal extrapleural chest wall hematoma. She was discharged on postoperative 46th day for other reasons and is doing fine today.

AbstractAbstract PDF

Bilateral chylothorax due to blunt trauma is extremely rare. We report a 74-year-old patient that developed delayed bilateral chylothorax after falling off a ladder. The patient had a simple 12th rib fracture and T12 lamina fracture. All other findings seemed normal. He was sent home and on the 5th day visited our emergency center at Halla Hospital with symptoms of dyspnea and lower back pain. Computer tomography of his chest presented massive fluid collection in his right pleural cavity and moderate amounts in his left pleural cavity with 12th rib fracture and T11-12 intervertebral space widening with bilateral facet fractures. Chest tubes were placed bilaterally and chylothorax through both chest tubes was discovered. Conservative treatment for 2 weeks failed, and thus, thoracic duct ligation was done by video assisted thoracoscopic surgery. Thoracic duct embolization was not an option. Postoperatively, the patient is now doing well and happy with the results. Early surgical treatment must be considered in the old patient, whom large amounts of chylothorax are present.

AbstractAbstract PDF
Purpose

The present study aimed to evaluate the influence of how the trauma care system applied on the management of trauma patient within the region.

Methods

We divided the patients in a pre-trauma system group and a post-trauma system group according to the time when we began to apply the trauma care system in the Halla Hospital after designation of a trauma center. We compared annual general characteristics, injury severity score, the average numbers of the major trauma patients, clinical outcomes of the emergency department, and mortality rates between the two groups.

Results

No significant differences were found in the annual patients’ average age (54.1±20.0 vs. 52.8±18.2, p=0.201), transportation pathways (p=0.462), injury mechanism (p=0.486), injury severity score (22.93 vs. 23.96, p=0.877), emergency room (ER) stay in minutes (199.17 vs. 194.29, p=0.935), time to operation or procedure in minutes (154.07 vs. 142.1, p=0.767), time interval to intensive care unit (ICU) in minutes (219.54 vs. 237.13, p=0.662). The W score and Z score indicated better outcomes in post-trauma system group than in pre-trauma system group (W scores, 2.186 vs. 2.027; Z scores, 2.189 vs. 1.928). However, when analyzing survival rates for each department, in the neurosurgery department, in comparison with W score and Z score, both W score were positive and Z core was higher than +1.96. (pre-trauma group: 3.426, 2.335 vs. post-trauma group: 4.17, 1.967). In other than the neurosurgery department, W score was positive after selection, but Z score was less than +1.96, which is not a meaningful outcome of treatment (pre-trauma group: ?0.358, ?0.271 vs. post-trauma group: 1.071, 0.958).

Conclusions

There were significant increases in patient numbers and improvement in survival rate after the introduction of the trauma system. However, there were no remarkable change in ER stay, time to ICU admission, time interval to emergent procedure or operation, and survival rates except neurosurgery. To achieve meaningful survival rates and the result of the rise of the trauma index, we will need to secure sufficient manpower, including specialists in various surgical area as well as rapid establishment of the trauma center.

AbstractAbstract PDF

Delayed esophageal rupture due to blunt injury is not new. However, rupture due to suspected barotrauma is very rare. We describe a case of esophageal rupture in a male 24-year-old patient after diving in shallow waters. The patient was quadriplegic and could not experience the typical chest pain related to rupture and resulting mediastinitis. The rupture was discovered 4 days after emergency decompressive laminectomy and fusion for his cervical spine. The rupture was evidently caused by barotrauma and was discovered four days after admission. He underwent primary closure and pericardial flap as a life-saving procedure.

AbstractAbstract PDF

Rib fixations for flail chest or displaced rib fractures are not a new technique. However, reports on rib fixations involving costal cartilage fractures are very few and surprisingly there are no reports of internal fixations involving only the costal cartilage in the English literature. The diagnosis is difficult and the necessity of the procedure may be quite controversial. Placing plates in screws into the costal cartilage alone may seem unstable and easily dislodged or stripped through the cartilage. We report a 31-year-old male scuba diver instructor who underwent rib fixations over his 7th and 8th costal cartilage ribs for severe pain. The procedure was done with conventional plates and screws. He had the plates and screws removed 2 months later due to lingering pain, but with them removed he is now quite happy with the results without pain. The procedure for fixation of painful overlapped costal cartilage is quite simple and can be done with the usual conventional methods, fixating plate and screws directly over the cartilage alone without fixation over the bony rib.

AbstractAbstract PDF
Standard open procedures for resection of the first rib in thoracic outlet syndrome can prove to be quite difficult with extensive incisions. A minimal invasive procedure can also be painstaking, but provides an attractive alternative to the more radical open procedures. We report the details of the technique with direct video footage of the procedure performed in a 41-year-old man with thoracic outlet syndrome done entirely by thoracoscopic methods.

AbstractAbstract PDF
PURPOSE
The role for minimally invasive surgery in chest trauma is vague, one that recently is more frequently performed, and one attractive option to be considered. Thoracoscopic surgery may improve morbidity, mortality, hasten recovery and shorten hospital stay.
METHODS
A total of 31 patients underwent video assisted thoracoscopic surgery for the treatment of blunt and penetrating chest trauma from June 9th, 2013 to March 21st, 2016 in Jeju, South Korea.
RESULTS
Twenty-three patients were males and eight patients were females. Their ages ranged from 23 to 81 years. The cause of injury was due to traffic accident in 17 patients, fall down in 5 patients, bicycle accident in 2 patients, battery in 2 patients, crushing injury in 2 patients, and slip down, kicked by horse, and stab wound in one patient each. Video assisted thoracoscopic exploration was performed in the 18 patients with flail chest or greater than 3 displaced ribs. The thoracoscopic procedures done were hematoma evacuation in 13 patients, partial rib fragment excision in 9 patients, lung suture in 5 patients, bleeding control (ligation or electrocautery) in 3 patients with massive hemothorax, diaphragmatic repair in two patients, wedge resection in two patients and decortication in 1 patient. There was only one patient with conversion to open thoracotomy.
CONCLUSION
There is a broad range of procedures that can be done by thoracoscopic surgery and a painful thoracotomy incision can be avoided. Thoracoscopic surgery can be done safely and swiftly in the trauma patient.

AbstractAbstract PDF
The primary and secondary survey was designed to identify all of a patient's injuries and prioritize their management. However 15 to 22.3% of patient with missed injuries had clinically significant missed injuries. To reduce missed injury, special attention should be focused on patients with severe anatomical injury or obtunded. Victims of blunt trauma commonly had multiple system involvement. Some reports indicate that inexperience, breakdown of estalished protocol, clinical error, and restriction of imaging studies may be responsible for presence of missed injury. The best way of reducing clinical significant of missed injuries was repeated clinical assessment. Here we report a case of severe blunt hepatic injury patient and pericardial injury that was missed in primary and secondary survey. After damage control surgery of hepatic injury, she remained hemodynamically unstable. Further investigation found cardiac tamponade during intensive care. This was managed by pericardial window operation through previous abdominal incision and abdominal wound closure was performed.

AbstractAbstract PDF
Ureteral trauma is rare, accounting for less than 1% of all urologic traumas. However, a missed ureteral injury can result in significant morbidity and mortality. The purpose of this case presentation is to suggest another method for early detection of ureteral injury in blunt traumatic patient. A 47-years-old man was injured in pedestrian traffic accident. He undergone 3-phase abdominal CT initially and had had a short-term follow-up simple. We suspected ureteral injury. Our final diagnosis of a ureteral injury was based on follow-up and antegrade pyeloureterography, he underwent emergency surgery. We detected the ureteral injury early and took a definitive action within 24 hours. In blunt trauma, if abnormal fluid collection in the perirenal retroperitoneal space is detect, the presence of a ureteral injury should be suspected, so a short-term simple X-ray or abdominal CT, within a few hours after initial abdominal CT, may be useful.

AbstractAbstract PDF
PURPOSE
Traumatic pancreatic injury is not common in abdominal trauma injury. However, the morbidity and the mortality rates of patients with pancreatic injury, which are related with difficulties of initial assessment, establishment of diagnosis, and treatment are relatively high. The aim of this study is to review our institution's experience and suggest a diagnosis and therapeutic algorithm for use in cases involving traumatic pancreatic injury.
METHODS
Eighteen(18) patients with blunt pancreatic injury from January, 2004 to October 2012 were included in this study. We analyzed treatment and diagnosis method, other organ injury, treatment interval, hospital stay and complications retrospectively.
RESULTS
Nine patients were treated with conservative medication and another nine patients were treated surgically. Complications occurred in nine patients, and one patient died due to intraventricular hemorrhage and subdural hemorrhage with multiple organ failure. Delayed surgery was performed in three cases. The early and delayed surgery groups showed difference in hospital stay and intensive care unit stay. Delayed surgery was associated with a longer hospital stay (p=0.007) than immediate surgery.
CONCLUSION
In blunt pancreatic trauma, proper early diagnosis and prompt treatment are recommended necessity. Based on this review of our experience, we also suggest the adoption of our institution's algorithm for cases involving traumatic pancreatic injury.

AbstractAbstract PDF
Severe blunt abdominal trauma frequently involves the liver. The development of nonsurgical treatment of liver trauma has led to more frequent appearance of unusual complications. A hepatic arterioportal fistula (APF) is a rare complication of liver trauma. We present a case of traumatic APF in a patient with liver trauma. A 31-year-old male visited our emergency department with pain in the right upper abdomen following a traffic accident. Initial physical exam and abdominal computed tomography (CT) revealed liver laceration with hemoperitoneum. An abdominal CT obtained on day 11 revealed early opacification of the right portal vein on the arterial phase. After we had come to suspect an APF of the liver, its presence was confirmed on angiography. It was subsequently managed by using transcatheter coil embolization. In patients with portal hypertension and no evidence or history of cirrhosis, one should consider an APF as a potential etiology if history of liver biopsy or penetrating trauma exists. In a patient with liver trauma, serial abdominal CT is important for early detection and treatment of an APF.
