目的:探讨研究下呼吸道感染与麻醉的相关因素以及临床预防措施。方法:对本院2006-03/2010-02收治的208例经临床手术麻醉患者的临床治疗及护理情况进行了临床监测并回溯式综合调查分析,对下呼吸道感染与麻醉的相关因素进行研究。结果:使用一次过滤器II-A组与使用复用式过滤器的II-B组患者、使用经气体消毒剂消毒喉镜的III-A组与使用喉镜行普通消毒的III-B组患者、麻醉前使用抗生素的IV-A组与麻醉前未使用抗生素的IV-B组患者相比,前者的细菌感染例数与下呼吸道感染例数组间相比均存在统计学差异,前者显著低于后者。结论:临床为控制下呼吸道感染的发生,应采取将气管导管、螺纹管、面罩、麻醉机等麻醉用设备器械进行定期的消毒清洁,尽量使用一次性过滤器,喉镜使用气体消毒并在术前适量使用抗生素等预防手段,以便规范化麻醉器械的消毒管理,进而达到控制和降低患者院内下呼吸道感染发生率的要求。
Objective: To investigate the related factors of lower respiratory tract infection and anesthesia and clinical preventive measures. Methods: The clinical treatment and nursing of 208 cases undergoing clinical surgical anesthesia admitted to our hospital from March 2006 to March 2010 were retrospectively analyzed. The related factors of lower respiratory tract infection and anesthesia were studied. Results: Patients in group II-A with primary filter and patients in group II-B with re-use filter had lower rates of mortality with Group III-A sterilized laryngoscopes using gas sterilizers and Group III-B patients with normal laryngoscopes There was a statistically significant difference in the number of cases of bacterial infection between the IV-A group receiving antibiotics before anesthesia and the IV-B group receiving no antibiotics before anesthesia, the former being significantly lower than the latter the latter. Conclusion: In order to control the occurrence of lower respiratory tract infection, anesthesia equipment such as endotracheal tube, threaded tube, face mask and anesthesia machine should be regularly disinfected and cleaned. The disposable filter should be used as far as possible. The laryngoscope should be sterilized with gas, Before the appropriate use of antibiotics and other preventive measures in order to standardize the disinfection management of anesthesia equipment, and then to control and reduce the incidence of nosocomial lower respiratory tract infection requirements.
