To compare the hemostatic efficacy and clinical applicability of a modified glove roll tourniquet versus a conventional rubber band tourniquet in digital nerve block surgery, providing evidence for optimizing intraoperative hemorrhage control. Eligible patients undergoing finger surgery were randomized into two groups: the experimental group (modified glove roll tourniquet, n = 30) and the control group (conventional rubber band tourniquet, n = 30). Tourniquet application time, total tourniquet duration, intraoperative blood loss, tourniquet pressure, postoperative wound healing, and Visual Analog Scale (VAS) scores on postoperative day 3 were recorded and compared. Statistical analysis was performed to assess intergroup differences. Four patients in the control group were excluded from the study. The experimental group demonstrated significantly better outcomes in intraoperative blood loss (p < 0.05) and tourniquet pressure (p < 0.05) compared to the control group. However, no statistically significant differences were observed in VAS scores, tourniquet application time, total tourniquet duration, or wound healing (p > 0.05). Additionally, clinical observations indicated that the modified glove roll tourniquet allowed greater flexibility during intraoperative positioning adjustments. Compared to the conventional rubber band tourniquet, the modified glove roll tourniquet provides more effective hemostasis with lower pressure. Its design also enhances intraoperative maneuverability, suggesting superior clinical utility.
