目的 比较钢丝和胸骨结扎在成人正中切口心脏手术中的相关指标并探讨胸骨结扎的 优点。方法 随机选择 2021 年 3 月至 2022 年 3 月在新疆医科大学第一附属医院心脏外科行正中切口心 脏手术的患者 163 例，其中结扎带组（n = 61）和钢丝组（n = 102）。比较两组的固定胸骨时间、镇痛剂的使用、不同时间段术后疼痛模拟评分、术后并发症的发生率及患者的治疗费用等指标。结果 结扎带组的 胸骨固定时间为 14.9（13.9，16.2）min，钢丝组的胸骨固定时间为 22.1（20.2，24.0）min，结扎带组胸骨固定 时间显著短于钢丝组（Z = -9.940，P < 0.001）；术后使用镇痛剂进行比较，差异有统计学意义（P < 0.05）， 不同时间段结扎带组患者术后疼痛视觉模拟评分均显著低于钢丝组，差异有统计学意义（P < 0.001）；结扎带组与钢丝组在表面感染、纵隔感染、骨髓炎、胸骨哆开及清创缝合等术后并发症指标进行比较，差异 均有统计学意义（P < 0.05）。钢丝组和结扎带组在 ICU 停留时间、总治疗费用及患者支付费用等指标进行比较，差异无统计学意义（P > 0.05）。结论 与钢丝相比，使用胸骨结扎带在术后疼痛和术后并发症方面 具有更大的临床优势。 

Objective To compare the indexes of steel wire and sternal ligation in adult midline incision cardiac surgery and to explore the advantages of sternal ligation. Methods A total of 163 patients who underwent midline incision cardiac surgery in the Department of Cardiac Surgery，the First Affiliated Hospital of Xinjiang Medical University from March 2021 to March 2022 were randomly selected，including sternum band group（n = 61）and steel wire group（n = 102）. The sternal fixation time，analgesic use，postoperative pain simulation score at different time periods，incidence of postoperative complications and treatment costs were compared between the two groups. Results The sternal fixation time of the sternum band group was 14.9（13.9，16.2）min，and that of the steel wire group was 22.1（20.2，24.0）min. The sternal fixation time of the sternum band group was significantly shorter than that of the steel wire group（Z = -9.940，P < 0.001）. The visual analogue score of postoperative pain in sternum band group was significantly lower than that in wire group at different time periods（P < 0.001）. There were statistically significant differences between the sternum band group and the steel wire group in postoperative complications such as surface infection，mediastinal infection，osteomyelitis，sternal debridement and suture（P < 0.05）. There was no significant difference in the length of stay in ICU，total treatment cost and patient payment between the steel wire group and the sternum band group（P > 0.05）. Conclusion Compared with the traditional steel wire，the sternum band has a greater clinical advantage in postoperative pain and postoperative complications.
