Key result
Flushing the femoral shaft cavity with carbon dioxide eliminated clinically detectable air emboli during total hip replacement, although transient falls in blood pressure persisted.
Why the study?
Does flushing the femoral shaft cavity with carbon dioxide prevent clinically detectable air emboli in patients undergoing total hip replacement?

Flushing the femoral shaft cavity with carbon dioxide during total hip replacement eliminates clinically detectable air emboli.
May eliminate detectable air emboli without preventing hypotension in hip replacement; leaves open clinical utility and requires prospective trials.
A study is described in which clinically detectable air emboli which occurred during total hip replacement were eliminated by flushing the femoral shaft cavity with carbon dioxide. Transient falls in blood pressure were still observed immediately after insertion of bone cement, and alternative mechanisms are discussed.
