双髋关节同期置换与分期置换的疗效比较

目的 对比分析双髋关节同期置换与分期置换的临床疗效，为同期双髋关节置换的临床应用提供依据。方法 选取2011年1月至2014年1月入住铜陵市人民医院行髋关节置换的60例患者作为研究对象，采用随机数字法，将患者分为同期置换组与分期置换组各30例，观察两组患者术中出血量、手术时间、C-反应蛋白（CRP）、D-二聚体、并发症及关节功能。结果 同期置换组患者术中出血量、总手术时间均低于分期置换组，两组比较差异有统计学意义（P<0.05）；术前及术后Harris评分两组比较差异无统计学意义（P>0.05）。术后同期置换组患者CRP水平高于分期置换组患者，两组比较差异有统计学意义（P<0.05）。术后两组患者深静脉血栓、感染等并发症比较差异均无统计学意义（P>0.05）。结论 同期双髋关节置换较分期置换有一定的优势，可以降低术中出血量、住院时间。

Comparative analysis of clinical efficacy of staged versus simultaneous bilateral hip joint replacement

Objective To compare and analyze the clinical efficacy of the staged versus the simultaneous bilateral hip joint replacement. Methods From Jan 2011 to Jan 2014, sixty patients ever treated with hip joint replacement in our hospital were selected as the research objects, and were equally divided into the staged group and the simultaneous group by random number table method. The blood loss, operation time, levels of C-reactive protein (CRP) and D-Dimer, postoperative complications and joint function between the two groups were observed and compared. Results The simultaneous group had lower intraoperative blood loss and shorter operation time than the staged group, and their differences were statistically significant (P<0.05), but there was no significant difference in the preoperative and postoperative Harris scores between the two groups (P>0.05). After replacement operation, the CRP levels of patients in the simultaneous group were significantly higher than those in the staged group (P<0.05), and such complications as deep vein thrombosis and infection occurred in the two groups were not significantly different (P>0.05). Conclusion The simultaneous bilateral hip joint replacement has an advantage of lower intraoperative blood loss and shorter hospitalization time, when compared with the staged bilateral hip joint replacement.
