目的 探究环抱式接骨器内固定术与克氏针肋骨内固定术治疗创伤性多发肋骨骨折患者的疗效。方法 以本院2021.01—2023.05期间医治的100例创伤性多发肋骨骨折患者为研究对象，依据不同手术方法分为研究组（n=53）、对照组（n=47），前者行环抱式接骨器内固定术，后者行克氏针肋骨内固定术。比较两组手术指标、手术前后血气指标[氧饱和度（SaO2）、动脉氧分压（PaO2）、动脉二氧化碳分压（PaCO2）]、呼吸功能[最高呼气流速（PEF）、第1s用力呼气容积（FEV1）、用力肺活量（FVC）]、疼痛数字评价量表（NRS）、并发症。结果 与对照组相比，研究组下床时间、镇痛药使用时间、手术时间、住院时间、骨折愈合时间均较短（P<0.05）；术后1W，与对照组相比，研究组SaO2、PaO2指标较高，PaCO2指标较低（P<0.05）；术后1W，与对照组相比，研究组PEF、FEV1、FVC指标较高（P<0.05）；与对照组相比，研究组术后NRS评分较低（P<0.05）；两组并发症发生率（1.89% VS 6.38%）相比，差异无统计学意义（P>0.05）。结论 环抱式接骨器内固定术能改善肋骨骨折患者血气指标，减少对呼吸功能损伤，减轻术后疼痛程度，缩短住院时间，加快康复进程。

Objective   To  explore  the  efficacy  of internal  fixation  techniques  on  traumatic  multiple  rib  fractures. Methods  A total of 100 patients with traumatic multiple rib fractures treated in the Taikang Tongji(Wuhan) Hospital during January 2021 to May 2023 were recruited and assigned into the study group(n=53) and control group(n=47) according to different surgical methods.Internal fixation using an embracing device was performed in the study group, and  internal  fixation  using  the  Kirschner  needle  was  conducted  in  the  control  group. The  surgical  indicators, blood gas before and after surgery, respiratory function(peak expiratory flow[PEF], forced expiratory volume in  1  s[FEV1], forced  vital  capacity[FVC]), the  numerical  rating  scale(NRS)  score  and  complications  were  compared  between the  two  groups. Results    Compared  with  those   of  the  control  group, the  time   of  off-bed  activities, duration   of using  analgesics, operation  time, length  of  stay  and  the  duration  of  fracture  healing  were  significantly  shorter  in the  study  group(r<0.05). At   1  week  after  operation, patients  in  the  study  group  had  significantly  higher  oxygen saturation(SaO2)  and  arterial  partial  pressure  of oxygen[p(O2)], but  lower  arterial  partial  pressure  of carbon  dioxide [p(CO2)]，r<0.05. At  1  week  after operation, PEF, FEV1  and FVC were  significantly higher in the  study group than those of the control group(r<0.05).The NRS score of the study group was significantly lower than that of the control group(r<0.05). There  was  no  significant  difference  in  the  incidence  of  complications  between  the  two  groups ( 1.89% VS 6.38%,r>0.05). Conclusion   The internal fixation using an embracing device effectively improves blood gas, reduces respiratory function injury and postoperative pain, shortens length of stay and accelerates the process of rehabilitation in patients with rib fractures.
