What is A severely injured patient with multiple injuries is brought to casualty. Primary survey done and patient is stabilized. What is the preferred investigation? and explain in detail?
Computed tomography(CT) from the head to pelvis with IV contrast, the so called 'whole body CT' (WBCT) is the gold standard investigation in patients with signs or symptoms of multiple injury or deranged physiology.There is no role for scanning selective bodysystems in the severely injured trauma patient. Wherever possible,WBCT should be performed as soon as possible during the patient's resuscitation. A provisional 'hot repo' can be issued within minutes to identify immediate life-threatening pathology to the trauma team. A more detailed definitive repo should be available within 30-60 minutes.Bailey and love 27e 324
