A prospective randomized controlled study on the effect of a novel exsanguination tourniquet in fresh closed distal radius fracture surgery.

Abstract

PurposeThis study aimed to evaluate the efficacy and safety of an elastic constriction ring compared to traditional pneumatic tourniquets in patients undergoing surgery for closed distal radius fractures.MethodsA total of 60 participants were enrolled, with 30 in the experimental group (elastic constriction ring) and 30 in the control group (traditional tourniquet). Key indicators assessed included preoperative exsanguination time, intraoperative blood loss, tourniquet-related complications, and so on.ResultsThe experimental group demonstrated a significantly shorter average exsanguination time (8.36 ± 2.72 s vs 55.98 ± 3.61 s) and lower intraoperative blood loss (12.07 ± 6.54 mL vs 17.07 ± 8.29 mL). No significant differences were observed in tourniquet time or operation time between the groups. Besides, adverse events related to the device are minimal in two groups.ConclusionsThe elastic constriction ring is an effective alternative to traditional pneumatic tourniquets, offering significant advantages in reducing exsanguination time and intraoperative blood loss without increasing complication rates.
