SNP hypotension may aid blood conservation in hip arthroplasty; leaves open confirmation versus alternatives in RCTs.
Does sodium nitroprusside induced hypotensive anesthesia reduce intraoperative blood loss compared to halothane, NLA, or epidural block in patients undergoing total hip arthroplasty?
Controlled hypotension with sodium nitroprusside or the use of epidural block reduces surgical bleeding during total hip arthroplasty compared to general anesthesia.
