简介：　　 [ 摘要 ] 目的 探讨记忆合金肋骨环抱器治疗多发性肋骨骨折的临床效果。方法 选取 2016 年 2 月～ 2019 年 2 月我院骨科收治的 102 例多发性肋骨骨折患者作为研究对象，根据随机数字表法分为对照组与观察组，每组各 51 例。对照组患者采用常规保守治疗，观察组患者采用记忆合金肋骨环抱器治疗，比较两组患者的骨折恢复效果、各项恢复指标、并發症总发生率、疼痛及肺功能情况。结果 观察组患者的治疗优良率为 96.08% ，高于对照组的 80.39% ，差异有统计学意义（ P<0.05 ） ; 观察组患者的呼吸频率恢复时间、动脉血氧饱和度（ SaO2 ）恢复时间、胸痛缓解时间、住院时间、骨折愈合时间均短于对照组，差异有统计学意义（ P<0.05 ） ; 观察组患者的并发症总发生率低于对照组，差异有统计学意义（ P<0.05 ） ; 观察组患者治疗后的视觉模拟量表（ VAS ）评分低于对照组，每分钟最大通气量百分比（ MVV% ）高于对照组，差异有统计学意义（ P<0.05 ）。结论 记忆合金肋骨环抱器治疗多发性肋骨骨折的临床效果显著，能够有效缩短胸痛持续时间，加快呼吸功能的恢复，促进骨折的早期愈合，降低并发症发生率，具有积极的临床意义。 　　 [ 关键词 ] 多发性肋骨骨折 ; 记忆合金肋骨环抱器 ; 临床效果 　　 [Abstract] Objective To investigate the clinical effect of memory alloy rib encircling device in the treatment of multiple rib fractures. Methods From February 2016 to February 2019 ， 102 patients with multiple rib fractures treated in orthopaedic department of our hospital were selected as the subjects ， and divided into control group and observation group by random number table method ， with 51 cases in each group. The control group used conventional conservative treatment ， and the observation group given memory alloy frame around treatment. The recovery effect of fracture ， the recovery index ， total incidence of complications ， pain and pulmonary function were compared between the two groups. Results The rate of excellent and good treatment was 96.08% ， higher than 80.39% in the control group ， and the difference was statistically significant （ P<0.05 ） . The recovery time of respiratory rate ， arterial oxygen saturation （ SaO2 ） recovery time ， chest pain relief time ， hospitalization time and fracture healing time in the observation group were shorter than those in the control group ， and the differences were statistically significant （ P<0.05 ） . The total incidence of complications in the observation group was lower than that in the control group ， and the difference was statistically significant （ P<0.05 ） . After treatment ， the visual analogue scale （ VAS ） score in the observation group was lower than that in the control group ， and the percentage of maximum ventilation per minute （ MVV% ） in the observation group was higher than that in the control group ， the differences were statistically significant （ P<0.05 ） . Conclusion The memory alloy rib enclasp has significant clinical effect in the treatment of multiple rib fractures ， which can effectively shorten the duration of chest pain ， accelerate the recovery of respiratory function ， promote the early healing of fractures and reduce the incidence of complications ， and has positive clinical significance.
