Population
290 patients scheduled for primary total hip replacement
Comparison
A-V Impulse System foot pump used for seven days… vs Enoxaparin 40 mg daily for seven days…
Design
RCT, randomized

Implication
Foot pumps may serve as an alternative to enoxaparin for DVT prophylaxis after hip replacement; extends mechanical options in orthopedic RCTs.
Structured PICO

P
Population
290 patients scheduled for primary total hip replacement
I
Intervention
A-V Impulse System foot pump used for seven days postoperatively
C
Comparator
Enoxaparin 40 mg daily for seven days postoperatively
O
Outcome
Prevalence of deep-vein thrombosis, determined by venography on the sixth, seventh, or eighth postoperative daysurrogate
A foot pump is a suitable alternative to low-molecular-weight heparin for DVT prophylaxis after total hip replacement, offering fewer soft-tissue bleeding side effects despite some patient tolerance issues.
