CPAS

Circumferential pelvic anti-shock sheeting. A. A sheet is placed under the pelvis. B. The ends are brought together anteriorly. C. Hemostats are used to secure the sheet snugly.

* A simple method for obtaining temporary pelvic stabilization when an external fixator cannot be applied is the application of a circumferential pelvic anti-shock sheet (CPAS).
* Advantages of this technique include the fact that it is inexpensive and readily available in all EDs. Special training is not required and the emergency physician can apply the sheet. Lower extremity and abdominal access is maintained after the sheet is placed.
* Caution is required in patients with lateral compression pelvic ring injuries or sacral neuroforaminal fractures. Forceful or aggressive CPAS application could worsen visceral injury or sacral nerve root injury in these instances.
