血沉及降钙素原在髋关节置换术后早期感染中的价值

目的：探讨血沉与血清降钙素原在髋关节置换术后早期感染中的诊断价值。方法回顾性分析我院近年来15例髋关节置换术后早期感染的患者（感染组）及无感染的17例患者（对照组）的临床资料，分析患者术前及术后血沉及血清降钙素原的检测情况。结果感染组与对照组术前血沉无明显差异，术后感染组与对照组血沉均加快，但感染组血沉明显快于对照组，两者差异有统计学意义（P ＜0．05）；感染组与对照组术前血清降钙素原水平相近，对照组术后水平较术前未升高，而感染组术后血清降钙素原明显升高，与对照组相比差异有统计学意义（P ＜0．05）。结论血沉及血清降钙素原为髋关节置换术后早期感染的敏感性及特异性均较高检测指标，对髋关节术后感染的早期诊断极有帮助，可作为髋关节术后有无感染的常用指标。

Values of blood sedimentation and procalcitonin in early infection after hip arthroplasty

Objective To investigate the diagnostic values of blood sedimentation and serum pro-calcitonin（PCT）in early infection after hip arthroplasty.Methods The clinical data of 15 patients with early infection after hip arthroplasty（infection group）and 17 patients without it（control group）in recent years were retrospectively reviewed.Preoperative and postoperative levels of blood sedimentation and serum PCT were analyzed for comparison.Results No significant differences in preoperative blood sedimentation were observed between the groups.Postoperative blood sedimentation increased in both groups,and level of the infection group was significantly higher（P 〈0.05）.Preoperative serum PCT levels were similar be-tween the groups.Postoperative serum PCT level in the infection group elevated significantly,but the level of control group was not（P 〈0.05）.Conclusion For early infection after hip arthroplasty,blood sedi-mentation and serum PCT are helpful indicators with certain sensitivity and specificity,and they may be commonly used for the early diagnosis of postoperative infection.
