Eksperimentel: Reinflation after early deflation
The tourniquet is released after cement implant fixation, and then reinflated, once arterial bleeding was controlled (Reinflation after early tourniquet deflation).

The tourniquet is released after cement implant fixation, and then reinflated, once arterial bleeding was controlled
Andre navne:
|
|
Ingen indgriben: No reinflation after early deflation
The tourniquet is released after cement implant fixation, and remained deflated without reinflation, even after hemostasis.
