PFNA治疗股骨转子间骨折的安全性及术后低氧血症的观察

目的:探讨PFNA治疗股骨转子间骨折的疗效及安全性,观察PFNA术后低氧血症的发生情况,并分析其相关影响因素.方法:选取104名股骨转子间骨折患者为研究对象,按随机数字法分为PFNA组54例与DHS组50例,分别给予PFNA内固定术与DHS内固定术治疗.比较两组手术相关情况以及疗效指标,观察并发症发生情况,分析术后低氧血症发生的相关因素.结果:PFNA组的手术时间、术中失血量、负重时间、骨折愈合时间均显著低于DHS组,Harris评分则显著高于DHS组;PFNA组的并发症发生率7.41%显著低于DHS组26.0%;患者于PNFA手术当天血氧分压降至最低,女性、高龄、麻醉方式为全麻以及术后血红蛋白、血细胞压积、血小板计数值下降幅度大均与PFNA术后低氧血症的发生有关.结论:PFNA手术治疗有助于促进患者骨折愈合与功能恢复,手术效率高且并发症发生率低,具有较好的疗效与安全性,PNFA术后低氧血症的发生与多种因素相关,应注意避免.

Safety of PFNA in treatment of intertrochanteric fractures and observation of postoperative hypoxia

Objective To investigate the efficacy and safety of PFNA in the treatment of intertrochanteric fractures, to observe the occurrence of postoperative hypoxia, and to analyze the related influencing factors. Methods 104 patients with femoral intertro-chanteric fractures were selected as the study subjects. According to the random number method, 54 cases of PFNA group and 50 cas-es in group DHS were treated with PFNA internal fixation and DHS fixation. To compare the two groups of surgery related conditions and efficacy indicators, to observe the incidence of complications, analysis of postoperative hypoxia related factors. Results In PFNA group, the operative time, blood loss, load time, fracture healing time were significantly lower than those of the DHS group. Harris score was significantly higher than that of DHS group; the PFNA group complication rate was 7.41% was significantly lower than that of DHS group 26.0%; patients in PNFA surgery on the day of the oxygen partial pressure was the lowest, female gender, advanced age, type of anesthesia for general anesthesia and postoperative hemoglobin, blood cell hematocrit, platelet count decreased significantly with PFNA postoperative hypoxemia associated. Conclusion PFNA treatment helps to promote patients with fracture healing and functional recovery, high operation efficiency and low complication rate, with better efficacy and safety, PNFA after operation is related to the oc-currence of hypoxemia with a variety of factors, should pay attention to avoid.
