Key result
A bipolar sealer device significantly reduced intraoperative (p=0.002) and postoperative (p=0.001) blood loss, and decreased transfusions by 73% compared to standard electrocautery.

Does a bipolar sealer device reduce blood loss and transfusion rates compared to standard electrocautery in patients undergoing primary total hip arthroplasty?
Effect estimate: 40% reduction
p-value: p=0.002 (intraoperative), 0.001 (postoperative)
The use of a bipolar sealer in total hip arthroplasty significantly reduces intra- and postoperative blood loss and transfusion requirements compared to standard electrocautery without affecting clinical outcomes.
Marulanda et al. (2008) conducted an RCT in primary total hip arthroplasty (n=50). bipolar sealer device vs. standard electrocautery was evaluated on intra- and postoperative blood loss (40% reduction, p=0.002 (intraoperative), 0.001 (postoperative)). A bipolar sealer device significantly reduced intraoperative (p=0.002) and postoperative (p=0.001) blood loss, and decreased transfusions by 73% compared to standard electrocautery.
