Patients with severe lung injury and hemorrhagic shock, may develop acute respiratory failure syndrome during resuscitation, and may require extracorporeal membrane oxygenation (ECMO) support to ensure adequate oxygenation to sustain life. In this case study, a 69 year-old female was hit by a motor vehicle whilst riding her bicycle. She was in a state of hemorrhagic shock due to polytrauma and was resuscitated with massive fluid transfusion during the initial management. After admission to the intensive care unit, she suffered from hypoxia which required mechanical ventilation using 100% oxygen. However, hypoxia did not improve, so she was placed on venoveno ECMO support after 4 days of intensive care treatment. Although trauma and bleeding are considered as relative contraindications for ECMO support, veno-veno ECMO allows for lung rest, and improvement of pulmonary function.

The retroperitoneum is a posterior space of the peritoneum, which has many visceral and vascular structures. Spontaneous retroperitoneal hemorrhages have variable causes, the most common of which are diseases of retroperitoneal organs. However, retroperitoneal hemorrhages may be caused by bare area injury. In this case study, a bare area was observed in the right upper quadrant (RUQ) of the retroperitoneum, the posterosuperior region of Couinaud liver segment 7 (bare area) is directly connected to the anterior pararenal space. The rupture or exophyte of the hepatocellular carcinoma on the bare area could invade the retroperitoneum, which may lead to inaccurate diagnosis of the condition. When the mass or the hemorrhage in the RUQ of the retroperitoneum is observed in computed tomography images, it is possible that ruptured hepatocellular carcinoma or a mass on the bare area of the liver, looks like a spontaneous retroperitoneal hemorrhage in the RUQ area for example a right adrenal hemorrhage.

Pyometra is a rare condition that is defined as the accumulation of purulent material in the uterine cavity caused by an occlusion to the natural drainage of the uterus. Pyometra cases are seldom reported. The symptoms of pyometra may be non-specific, resulting in a delay or misdiagnosis that may subsequently increase the risk of perforation of the pyometra. Once a pyometra ruptures, the patient develops acute abdominal and generalized peritonitis. This case report describes diffuse peritonitis caused by the spontaneous perforation of a pyometra in a woman who was diagnosed preoperatively and treated successfully by emergency laparotomy.

It is extremely difficult to achieve hemostasis in the case of proximal amputation of major limbs, and especially in the case of a proximal upper arm amputation, which is adjacent to the axilla. A 30-year-old male sustained a traumatic proximal left upper extremity amputation resulting in hypovolemic shock. A median sternotomy was performed to clamp the left subclavian artery. The completely transected brachial artery was reconstructed with an artificial vascular graft and the transected nerves were repaired. With simultaneous rehabilitation, the patient recovered from the hypovolemic shock and ischemic injury of the arm. Performing a median sternotomy for proximal clamping of the transected artery allowed control of the bleeding which could not be controlled by a pressure cuff. This procedure may be considered a safe and effective surgical option for patients with traumatic proximal upper extremity amputation.

Purpose: Intensive IV insulin infusion therapy has been applied widely to critically ill patients. However, IV insulin protocols are complex, and require repeated calculations. The purpose of this study was to evaluate the safety and efficiency of a computerized insulin infusion (CII) protocol to replace manual insulin infusion protocols, for glucose control in critically ill patients. Methods: This was an observational study (September 2016 to January 2017) of 43 patients in ICU whose blood glucose level was between 140-180 mg/mL and could not be controlled by the conventional manual insulin protocol. The CII protocol was integrated in to the electronic medical record order system, and automatically calculated the insulin infusion dose and blood sugar test (BST) interval. BSTs were taken 48 hours pre- and post-initiation of the CII protocol. The proportion of BSTs in the normal (70-180 mg/mL), hypoglycemic (70 mg/mL), and severe hyperglycemic (> 250 mg/mL) range were recorded. Results: The mean number of BSTs performed before using the CII protocol was 10.3/person and 0.4/hour, and after implementing the protocol, increased to 21.7/person and 0.7/hour. The mean glucose level (281.4 mg/mL) decreased after using the CII protocol (195.5 mg/mL; p < 0.001). The percentage of BSTs within normal range increased from 22.5% to 44.9% after implementing the protocol (p < 0.001). Severe hyperglycemia (> 250 mg/mL) decreased from 47.3% to 17.9% after protocol implementation (p = 0.020). Conclusion The CII protocol safely and successfully maintained a normal glucose range, and decreased severe hyperglycemia in intensive care patients.

Purpose: Thromboelastography (TEG) was investigated for the diagnosis of coagulopathy compared with traditional coagulation tests, in association with disease severity in patients with severe sepsis or septic shock. Methods: Retrospective data was collected from a single center between January 25th to March 24th, 2016. There were 18 patients with severe sepsis or septic shock admitted to intensive care units included in this study. Laboratory tests including TEG were performed at admission. Disease severity was measured using the Simplified Acute Physiology Score III, Sequential Organ Failure Assessment score, and the level of lactate. Results: There were 18 patients (61% males; median age, 60.5 years) who were diagnosed with severe sepsis, or septic shock requiring a norepinephrine infusion (n = 10, 55.6%). Of these, 4 patients had traditional coagulation tests, and TEG profiles which confirmed hypercoagulability. Eight patients had follow-up tests 48 hours post-admission with a Sequential Organ Failure Assessment score of 6.5 (3-9.5) at admission, decreasing to 4 (2-11) after 48 hours (although not significantly lower), however, the lactate level decreased statistically significantly from 2.965 at admission, to 1.405 mmol/L after 48 hours (p < 0.05). The TEG profiles tended to normalize after 48 hours compared with admission, but there was no statistically significant difference. Conclusion Coagulopathy with severe sepsis or septic shock patients can be life-threatening, therefore it is important to diagnose coagulopathy early and precisely. TEG can be a feasible tool to confirm coagulopathy with traditional coagulation tests.

Purpose: The occurrence of trauma-related delirium following postoperative abdominal surgery is associated with a poor prognosis. The purpose of this study was to identify predictive risk factors for trauma-related delirium. Methods: Trauma patient data from a regional trauma center were retrospectively collected from August 2015 to December 2016. The primary inclusion criteria were patients diagnosed with traumarelated delirium following abdominal trauma surgery. Head trauma patients and those under 18 years of age were excluded from this study. A multivariate logistic regression analysis was performed to identify the risk factors associated with trauma-related delirium. Results: Of the 255 trauma patients who met the inclusion criteria, 32 (12.5%) were diagnosed with delirium. The mean values for the age of the patients, Injury Severity Score, Glasgow Coma Scale score, and length of intensive care unit stay were 52.1 ± 17.8 years, 16.9, 14, and 7.1 days, respectively. Among the measured parameters, age [odds ratio (OR), 1.03; 95% confidence interval (CI), 1.01-1.06; p = 0.022)], sex (OR, 0.125; 0.03-0.55; p = 0.006), hemoglobin level (OR, 0.875; CI, 0.68-0.98; p = 0.03), length of stay in the intensive care unit (OR, 1.12; CI, 1.03-1.22; p = 0.01), and having an abdominal operation (OR, 2.92; CI, 1.10-7.23; p = 0.011) showed strong correlations with trauma-related delirium. Conclusion This study showed that abdominal surgery was strongly associated with delirium in patients with traumatic abdominal injury. Thus, changes in consciousness should be carefully monitored following surgery.

Purpose: This study aimed to independently analyze pediatric trauma characteristics from a single institution in Korea to gain a better understanding of pediatric injury. Methods: A retrospective review was conducted at a single, non-regional trauma center using data from 303 children (< 8 years) who presented at the emergency department (March 2010 to December 2018), to determine the frequency and details of admissions. Demographic variables [sex, age, mechanism of injury, regions of trauma on the body, score of the injury (abbreviated injury scale)] location where the trauma occurred, injury severity score, history of surgery, mortality, and cumulative length of hospital stay], were used to evaluate the severity of the trauma. Results: The frequency of admissions was typically high for all seasons except winter. The most common mechanism of injury was due to falls; however, this was not the case for 1-, 2-, and 4-yearolds. The most common location where trauma occurred was at home for the age group 1-3 years, and outside the home for children aged 4 years or older. The most common area of injury was the extremities (65.7%). The median injury severity score was 4 (range, 4-4), and the median hospital stay was 4 days (range, 2-6). The overall mortality rate was 0.3%. Conclusion Although mortality from trauma is low among pediatric patients, we must continue to improve treatment outcomes. Hospitals lack sufficient resources for pediatric trauma specialists, however to improve patient outcome, it is necessary to recognize age-specific trauma characteristics.

Aneurysm of the pancreaticoduodenal artery is a rare finding that can be divided into true and false aneurysm. True aneurysm of the pancreaticoduodenal artery is more common and is usually due to atherosclerosis or celiac stenosis. Herein we present a rare case of a 59-year-old male patient with a spontaneous rupture of an idiopathic aneurysm of the inferior pancreaticoduodenal artery who was successfully treated with angiographic coil embolization

Explosions in the abdomen during surgery are rare. This article reports a case of an intra-abdominal explosion caused by flammable gas ignited by electrocautery during a laparotomy. The patient’s small intestine, left colon, and peritoneum were burned superficially, but recovered without any specific symptoms. Despite the rarity of this phenomenon, surgeons should be aware of the possibility of an explosion due to intra-abdominal gas, and consider the use a scalpel rather than electrocautery when opening the peritoneum of patients with pneumoperitoneum.
