OBJECTIVE
The aim of this study was to compare the effect of tourniquet time less than or in excess of 120 minutes on foot surgery wound healing.
NULL HYPOTHESIS
A tourniquet time of over 120 minutes will not affect wound healing in foot surgery.
DESIGN, SETTING, PARTICIPANTS AND METHOD: A retrospective comparative cohort analysis was performed on 96 patients undergoing complex hindfoot surgery in a large central teaching hospital. Fifty-five patients receiving tourniquet pressure for >120 minutes and 41 receiving <120 minutes of tourniquet pressure were identified from electronic case records. The primary outcome was surgical wound healing. Secondary outcomes were discharge date and complication rate.
RESULTS
There was no significant difference in reported time for wounds to heal in the <120-minute or >120-minute cohort. There were no other significant differences in secondary clinical outcomes and no significant variations in patient demographics.
CONCLUSION
This study suggests that tourniquet times from 2 to 3 hours in foot and ankle surgery with pressures up to 300 mmHg are not associated with a significant effect on wound healing.
目的
本研究旨在比较止血带使用时间少于或超过120分钟对足部手术伤口愈合的影响。
零假设
止血带使用时间超过120分钟不会影响足部手术的伤口愈合。
设计、地点、参与者与方法：对一家大型中心教学医院中96例行复杂后足手术的患者进行回顾性比较队列分析。从电子病例记录中识别出55例接受止血带压力超过120分钟的患者和41例接受止血带压力少于120分钟的患者。主要结局为手术伤口愈合情况。次要结局为出院日期和并发症发生率。
结果
在止血带使用时间少于120分钟或超过120分钟的队列中，报告的伤口愈合时间无显著差异。次要临床结局无其他显著差异，患者人口统计学特征也无显著变化。
结论
本研究表明，在足踝手术中，止血带使用时间为2至3小时且压力高达300 mmHg对伤口愈合无显著影响。
