【摘要】 目的 探究下颌水平阻生智齿拔除术后感染患者的影响因素及预防对策,为患者的治疗提供参考。方法 回顾性分析龙岗区第五人民医院口腔科2016年12月至2018年12月间收治的行下颌水平阻生智齿拔除术患者临床治疗情况。选取其中120例术后感染患者作为观察组,同时选取120例术后未感染患者作为对照组,分析患者术后感染特点、影响因素及预防对策。结果 观察组患者术后感染部位主要分布在创面,占75.8%,其次分别为口腔黏膜和呼吸道,各占18.3%和5.8%;观察组患者中共分离出病原菌132株,其中革兰阴性菌105株,占79.5%,革兰阳性菌19株,占14.4%,真菌8株,占6.1%;患者术后感染相关危险因素显示,术后出血、术前预防性使用抗菌药物以及手术时间均与患者术后感染有相关性(P<0.05);观察组患者术后并发症发生率为12.5%,明显高于对照组的5.8%,差异有统计学意义(P<0.05)。结论 下颌水平阻生智齿拔除术后,患者会由于多种因素引起术后感染,针对患者感染情况,可在术前采取针对性的预防措施,以提高治疗效果。

【Abstract】 Objective To explore the influencing factors and preventive measures of the infection after impact-ed mandibular third molar extraction, and provide reference for the treatment of patients. Methods A retrospective anal-ysis was made of the clinical treatment of the patients who underwent impacted mandibular third molar extraction be-tween December 2016 and December 2018 in the Department of Stomatology, the Fifth People's Hospital of LonggangDistrict of Shenzhen. A total of 120 cases of postoperative infection were selected as the observation group, and 120 cas-es of uninfected patients were selected as the control group. The postoperative infection characteristics, influencing fac-tors, and preventive measures were analyzed. Results The postoperative infection sites of the observation group weremainly distributed in the wound surface, accounting for 75.8%, followed by oral mucosa and respiratory tract, respec-tively, accounting for 18.3% and 5.8%. In the observation group, 132 strains of pathogens were isolated, of which 105strains were Gram-negative bacteria (accounting for 79.5% ), 19 strains were Gram-positive bacteria (accounting for14.4%), 8 were fungi (accounting for 6.1%); the risk factors of postoperative infection showed that bleeding, prophy-lactic use of antibiotics and operation time were correlated with postoperative infection (all P<0.05); the incidence ofpostoperative complications was 12.5% in the observation group, which was significantly higher than 5.8% in the con-trol group (P<0.05). Conclusion After impacted mandibular third molar extraction, the patient may cause postopera-tive infection due to various factors. For the patient's infection, targeted preventive measures can be taken before surgeryto improve the treatment effect.
