RESUMEN
Purpose@#A tracheostomy is often used to wean patients off the ventilator, as it helps maintain extracorporeal membrane oxygenation (ECMO) without sedation. A percutaneous dilatational tracheostomy (PDT) performed in critically ill patients is widely accepted, however, its feasibility and safety in ECMO is unclear. @*Methods@#This retrospective observational study included 78 patients who underwent a PDT and ECMO at the surgical intensive care unit (SICU) in a tertiary hospital between January 1, 2016 and December 31, 2019. We analyzed their medical records, including PDT-related complications and clinical variables. @*Results@#The median values of hemoglobin, platelet count, international normalized ratio, partial thromboplastin time, and activated partial thromboplastin time before the tracheostomy were 9.2 (8.5-10.2) g/dL, 81 (56-103) × 103/dL, 1.22 (1.13-1.30), 15.2 (14.3-16.1) seconds, and 55.1 (47.4-61.1) seconds, respectively. No clotting was observed within the extracorporeal circuit, however, minimal bleeding was observed at the tracheostomy site in 10 (12.8%) patients. Of 4 patients with major bleeding, local hemorrhage was controlled in 3 patients, and intratracheal bleeding continued in 1 patient. The mortality rate was 60.9% and 57.1% in the complication and no-complication group, respectively. The durations of SICU stay, hospital stay, and mechanical ventilation were not statistically different between the groups. @*Conclusion@#A PDT performed in critically ill patients was associated with a low rate of bleeding. Complications did not appear to significantly affect the patient outcome. PDT can be performed in patients who usually require a tracheostomy to maintain ECMO.
RESUMEN
Purpose@#Despite advances in diagnostic and imaging technologies, the diagnosis of traumatic hollow viscus injury (HVI) remains a great challenge in clinical practice. This study aimed to determine the accuracy of computed tomography (CT) in the diagnosis of HVI in emergent blunt trauma patients. @*Methods@#The study was conducted on patients with abdominal trauma who were admitted to our center, regional emergency center, Kyung Hee University Medical Center, between January 2008 and December 2018. The clinical data of patients with abdominal trauma who underwent CT and abdominal surgery within 24 hours of hospitalization were analyzed to determine the diagnostic capacity of CT. @*Results@#In total, 156 patients were included in the study. There were 88 cases of blunt trauma. Among these patients, 27 were diagnosed with HVI using CT, and 38 patients were diagnosed with HVI in the operating room. The median injury severity score for these patients was 10.0, the revised trauma score was 7.841, and the trauma injury severity score was 0.96. The sensitivity and specificity of CT in predicting HVI in these patients were 65.8%, and 96.0%, respectively. The positive and negative predictive values were 92.6%, and 78.7%, respectively. @*Conclusion@#In urgent situations, CT findings alone are insufficient for diagnosing HVI. Further research on the HVI diagnostic capacity of CT is required.
