For trauma patients with severe shock, massive fluid resuscitation is necessary. However, shock and a large amount of fluid can cause bowel and retroperitoneal edema, which sometimes leads to abdominal compartment syndrome in patients without abdomino-pelvic injury. If other emergent operations except intraabdomen are needed, a distended abdomen is likely to be recognized late, leading to multiple organ dysfunction. Herein, we report two cases of a 23-year-old woman who was in a car accident and a 53-year old man who was pressed on his leg by a pressing machine; severe brain swelling and popliteal vessel injury were diagnosed, respectively. They were both in severe shock and massive fluid resuscitation was required in the emergency department. Distended abdomen was recognized in both the female and male patients immediately after neurosurgical operation and immediately before orthopaedic operation in the operating room, respectively. Decompressive laparotomy revealed massive ascites with retroperitoneal edema.

Trauma surgeons' roles in a national hospital in Korea changed during the COVID-19 pandemic. In this study, we report on their roles over a 15-month period (March 2020 to May 2021) including the eight months where the hospital was a COVID-19-only hospital. Despite shortages in medical resources including medical personnel, and intensive care unit (ICU) beds, the trauma surgeons helped to control the public health problem by assuming various roles including working in another COVID-19 ICU in Dae-gu, treating trauma patients with COVID-19 or those who needed self-quarantine, being in charge of care for some COVID-19 patients in the ICU (for two months), and performing the role of a rapid response team member for COVID-19 ICU patients. In this report, we emphasize how trauma surgeons, along with intensivists, played an active role in treatment of COVID-19 patients, and helped prevent the collapse of the healthcare system within the hospital during the pandemic.

When a patient with severe trauma is admitted to the emergency room (ER), they are evaluated before transfer to either the intensive care unit (ICU) or operating room. To minimize the time until a definitive treatment can be provided, direct operating room resuscitation can be performed. In this hospital the ER was closed during the hospital’s transition to a coronavirus disease 2019-dedicated hospital, and direct ICU resuscitation for patients with trauma was performed for a short period. To perform effective trauma resuscitation, all ICU beds were reorganized to achieve a modified, experienced nurse: patient ratio (1:2-3) and 2 beds were assigned for trauma ICU resuscitation alone. The equipment for initial resuscitation was installed and ICU nurses received training. Consultations with the hospital administration, nursing, and pharmaceutical departments were completed in advance to avoid formal problems. Conversion of the ICU for direct resuscitation procedures was performed in 4 patients.

Purpose: Tracheostomy is a procedure which requires careful selection of tracheostomy tube size, because it can significantly impact patient outcomes. However, in situations where radiological imaging is unavailable for measuring the tracheal inner diameter (ID), it can be estimated using the patient's height, weight, and sex. This study aimed to develop a method for estimating tracheal ID. Methods: A retrospective study was conducted on 468 adult patients who underwent chest computed tomography and chest X-ray at the National Medical Center from 2019 to 2021. Tracheal ID at the level of the jugular notch was measured and cross-checked. The correlation of the patient's body size and sex was then checked with tracheal ID and a regression equation was obtained to estimate tracheal ID. Results: Height showed the greatest correlation with tracheal ID, followed by either ideal body weight (IBW) or adjusted body weight (ABW). The regression equation to estimate tracheal ID was as follows: “Expected ID of the trachea (mm)” = [11.0781 + (1.9682 for Male or 1 for Female)] + [7.3767 × height (cm)] - {0.8022 × [√ IBW (kg) for healthy weight or ABW (kg) for obese]}. The equation was applied to determine appropriate tracheostomy tube sizes. Conclusion Tracheal ID can be estimated using patient sex, height, and either IBW or ABW. By providing a practical method for estimating tracheal ID, the derived regression equation can serve as a valuable tool for healthcare professionals in emergency situations, which may reduce tracheostomy complication rates and deliver better patient outcomes.

Coronavirus disease was first reported in December 2019, and the World Health Organization declared it as a pandemic on March 11, 2020. The virus is known to attack various vital organs, including the respiratory system. Patients sometimes require positive pressure ventilation and tracheostomy. Because tracheostomy is a droplet-spreading procedure, medical staff should protect themselves against the risk of transmission of this contagious viral disease. In our case, we performed tracheostomy for a 70-year-old man with coronavirus disease 2019 (COVID-19) who had required more oxygen with gradual weakness of respiratory muscle to maintain his arterial oxygen saturation. We focused on the risks of the medical staffs and patients, and minimized them at the same time using temporary balloon over-inflation, pre-operative adjustment of endotracheal tube position, and attachment of a transparent film dressing to the surgical field without stopping the ventilator while following routine safety measures. Fourteen days after the tracheostomy, all participating medical staff members were healthy and asymptomatic. The patient was discharged 105 days after the COVID-19 diagnosis.

When treating trauma patients with severe hemorrhage, massive transfusions are often needed. Damage control resuscitation strategies can be used for such patients, but an adequate fresh frozen plasma: packed red blood cell (FFP:PRBC) administration ratio must be established. We retrospectively reviewed the medical records of 100 trauma patients treated with massive transfusions from March 2010 to October 2012. We divided the patients into 2 groups according to the FFP:PRBC ratio: a high-ratio (> or =0.5) and a low-ratio group (<0.5). The patient demographics, fluid and transfusion quantities, laboratory values, complications, and outcomes were analyzed and compared. There were 68 patients in the high-ratio and 32 in the low-ratio group. There were statistically significant differences between groups in the quantities of FFP, FFP:PRBC, platelets, and crystalloids administered, as well as the initial diastolic blood pressure. Bloodstream infections were noted only in the high-ratio group, and the difference was statistically significant (P=0.028). Kaplan-Meier plots revealed that the 24-hr survival rate was significantly higher in the high-ratio group (71.9% vs. 97.1%, P<0.001). In severe hemorrhagic trauma, raising the FFP:PRBC ratio to 0.5 or higher may increase the chances of survival. Efforts to minimize bloodstream infections during the resuscitation must be increased.
