[Use of portable computed tomography in non-transportable patients on the intensive care unit: preclinical...

To evaluate different concepts of the application of a portable CT (PCT) directly in a patient's ICU room versus in a specially designed interventional suite (IS).

13 patients with maximum ICU treatment were examined by PCT and assessed with regard to their health status by ICU scores (TISS 28, MODS). Only patients with a therapeutic intervention scoring system 28 (TISS 28) value of 40 or greater were included in the study. A TISS 28 value of 40 or more characterizes a patient requiring maximal ICU treatment. Patients were examined by PCT either in the patient's room or in the IS on the ICU. Scanning time and personnel resource expense were determined. The multiple organ dysfunction score (MODS) was utilized for patient characterization.

An average of 1.4 hours was needed to perform a PCT scan in the interventional room. A minimum of 4.5 hours or up to a maximum of 7.2 hours were required to perform a bedside scan in the patient's room. There is a noticeable difference between patients with respect to TISS 28. Patients examined by bedside CT were more acutely ill than the others by reason of MODS (8 - 18 patient-room group vs. 3 - 12 IS group).

PCT performed on an ICU assures optimal treatment of patients during CT examination. Portable CT had more time exposure and required more personnel resources than examination in the IS. All PCT examinations performed directly in the patient's room demonstrated the diagnostic value and had direct therapeutic consequences.
