96例骨科术后伤口感染危险因素调查与分析

目的 分析调查96例骨科术后伤口感染的危险因素.方法 选取2004年1月-2011年12月骨科4623例手术中发生切口感染的96例患者为研究对象,将其感染发生率及与感染发生相关的患者个人基本资料、治疗及其他情况进行研究分析.结果 所有患者伤口感染发生率为2.08％,其中手术时间≥3h的感染发生率为3.03％,高于＜3 h者；急诊手术的感染发生率为4.28％,高于择期手术；Ⅲ类切口为3.06％,高于Ⅰ、Ⅱ类；下肢骨折为2.70％,高于上肢骨折；住院时间≥2周为3.27％,高于＜2周者；年龄＞60岁者为2.94％,高于≤60岁者；并发基础疾病≥3种者为8.00％,高于＜3种者；术前合并其他感染者为7.02％,高于无感染者；抗菌药物应用种类较多者为6.43％,高于其他患者；差异均有统计学意义(P＜0.05).结论 96例骨科术后伤口感染的发生与个人基本资料、治疗及其他情况有关,应给予足够的重视.

Risk factors for wound infections in 96 patients after orthopedic surgery

OBJECTIVE To investigate and analyze risk factors for the wound infections in 96 patients after the surgery in department of orthopaedics.METHODS A total of 96 patients with wound infections were selected as the as research objects from 4623 patients who underwent surgery in department of orthopaedics from Jan 2004 to Dec 2011,and the incidence of infections,the patients′ personal status,and treatment status that were related to the infections were studied.RESULTS The incidence rate of the infections in all the patients was 2.08%,the incidence of the infections was 3.03% in the patients with the operation duration more than 3 hours,which was higher than that in the patients with the operation duration less than 3 hours;the incidence was 4.28% in the patients who underwent emergency operation,higher than that of the patients who received the selective operation;the incidence of the type Ⅲ incision infection was 3.06%,higher than that of typeⅠ or type Ⅱ incision infections;the incidence of the lower limb fracture was 2.70%,higher than that of the upper extremity fracture;the incidence of the infections in the patients with hospitalization duration more than 2 weeks was 3.27%,higher than that of the patients with the hospitalization duration less than 2 weeks;the incidence of the patients aged more than 60 years old was 2.94%,higher than that of the patients aged less than 60 years old;the incidence of the patient combined with more than 3 underlying diseases was 8.00%,highe than that of the patients combined with less than 3;the incidence of the patients with preoperative infections was 7.02%,higher than that of the patients without preoperative infections;the incidence of the patients who used various antibiotics was 6.43%,higher than that of other patients;the differences were statistically significant(all P<0.05).CONCLUSION The wound infections in 96 patients after the surgery in department of orthopaedics are related to the personal status,treatments status and others,which should be attached great importance.
