Key result
Controlled hypotension with sodium nitroprusside significantly reduced mean surgical blood loss by 826 ml compared to normotension during total hip replacement.

Does controlled hypotension using sodium nitroprusside reduce surgical haemorrhage in patients undergoing total hip replacement?
Population
50 patients undergoing total hip replacement operations.
Comparison

May support blood conservation in hip arthroplasty; leaves open need for RCTs to confirm safety and causality.
Does controlled hypotension using sodium nitroprusside reduce surgical haemorrhage in patients undergoing total hip replacement?
Mean Difference: 826
Absolute Event Rate: 212% vs 1038%
p-value: p=<0.001
Controlled hypotension with sodium nitroprusside significantly reduces surgical blood loss during total hip replacement compared to normotensive surgery.
Vazeery et al. (1979) studied Coxarthrosis (n=50). Controlled hypotension with sodium nitroprusside vs. Normotension was evaluated on Surgical haemorrhage (blood loss during operation) (MD 826 ml, p=<0.001). Controlled hypotension with sodium nitroprusside significantly reduced mean surgical blood loss by 826 ml compared to normotension during total hip replacement.
