近年来,随着创伤性诊疗技术的广泛开展以及广谱抗生素、激素的广泛应用,血流感染的发病率有逐年增高趋势,严重影响着患者的康复和预后,是导致患者死亡的重要因素。血流感染的危险因素包括宿主因素、医院因素、致病菌因素等。预防措施包括保证中央静脉穿刺的安全、用抗生素浸泡导管、彻底清洗手、合理使用抗生素、重视监测工作等。积极治疗原发疾病,去除可能的诱发因素,严格无菌操作,合理使用抗菌药物是降低血流感染发生率,提高治愈率的关键。
In recent years, with the widespread application of traumatic diagnosis and treatment techniques and the broad application of broad-spectrum antibiotics and hormones, the incidence of bloodstream infections has been increasing year by year, seriously affecting the rehabilitation and prognosis of patients and is an important factor leading to the death of patients. The risk factors of bloodstream infection include host factors, hospital factors, pathogenic bacteria and so on. Preventive measures include ensuring the safety of central venipuncture, immersing catheters with antibiotics, thorough hand washing, rational use of antibiotics, monitoring and more. Active treatment of primary disease, removal of possible triggers, strict aseptic technique, rational use of antimicrobial agents is to reduce the incidence of bloodstream infection and improve the cure rate of the key.
