Abstract
Background: Injury-related visits to the emergency department (ED) account for 34.2% of all visits. Rapid evaluation, management, and disposition are important steps in ED throughput. The early assessment of a potentially unstable trauma patient must be both rapid and unequivocal to best direct the diagnostic and therapeutic measures in each relevant case. Ultrasound is one of the most fundamental components of care of the injured patients that may help physicians to prevent diseases or severe complications of trauma prior to becoming completely apparent with irreversible consequences for the patients. The ability to obtain images rapidly and correlate to the clinical scenario has several advantages, particularly for unstable or potentially unstable trauma patients. These advantages include identifying immediately life threatening injuries such as pneumothorax, hemothorax, or pericardial tamponade, as well as aiding decision making regarding additional imaging studies such as plain radiographs or computed tomography (CT) scans The aim of the work: The purpose of this study was to evaluate the role of multiple modalities of ultrasound in initial assessment of polytrauma patients. Patients: This is a prospective study was conducted over 100 trauma patients admitted to Emergency Hospital Mansoura University over a year from May 2018 to May 2019. Methods: All patients subjected to resuscitation, history taking, clinical examination, multiple modalities of us including E-FAST, chest US and ECH; other radiological and laboratory invetstigations. Results: There was a statistically significant value of multiple modalities of ultrasound in rapid and early diagnosis of potentially life threating chest, abdominal and cardiac injuries related to trauma in the initial assessment of polytrauma patients prior to other additional nvestigations. Conclusion:. Multiple modalities of Ultrasound (MMUS) has significant value in initial assessment of life threatening conditions of trauma with acceptable sensitivity and high specificity, it has the advantages of being inexpensive, portable and readily available, as well as allowing multi-planar imaging and being free of ionizing radiation. The major limitation of ultrasound remains that it is operator dependent. Ultrasound is also patient dependent as the examination may be limited by morbid obesity.Recommendations: using multiple modalities of ultrasound (MMUS) in managing trauma patients as part of the primary trauma survey performed on all polytrauma patients in the emergency department as well as to be a part of pre-hospital protocols performed on scene or during transportation for early identification and management of life threating conditions which requires adequate and periodic training of medical personnel, emergency physician by radiologists to perform essential maneuvers of MMUS.
