Purpose:
The initial assessment of severely injured patients in the resuscitation room requires a systematic and quickly performed survey. Whereas the Advanced Trauma Life Support (ATLS®)-based algorithm recommends focused assessment with sonography in trauma (FAST) among others, recent studies report a survival advantage of early whole-body computed tomography (WBCT) in haemodynamically stable as well as unstable patients. This study assessed the opinions of trauma surgeons about the early use of WBCT in severely injured patients with abdominal trauma, and abdominal CT in patients with isolated abdominal trauma, during resuscitation room treatment.
Methods:
An online cross-sectional survey was performed over 8 months. Members of the Swiss Society for Surgery and the Austrian and German associations for trauma surgery were invited to answer nine online questions.
Results:
Overall, 175 trauma surgeons from 155 departments participated. For haemodynamically stable patients, most considered FAST (77.6%) and early CT (82.3%) to be the ideal diagnostic tools. For haemodynamically unstable patients, 93.4% considered FAST to be mandatory. For CT imaging in unstable patients, 47.5% agreed with the use of CT, whereas 52.5% rated early CT as not essential. For unstable patients with pathological FAST and clinical signs, 86.8% agreed to proceed with immediate laparotomy.
Conclusions:
Most surgeons rely on early CT for haemodynamically stable patients with abdominal trauma, whereas FAST is performed with similar frequency and is prioritized in unstable patients. It seems that the results of recent studies supporting early WBCT have not yet found broad acceptance in the surgical community.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
