术前漱口预防全麻术后呼吸道感染的临床研究

目的探讨全麻插管患者术后呼吸道感染的预防方法。方法将 2 4 0例普外科行全麻插管手术患者随机分为对照组和观察组 ,各 12 0例。观察组术前 2d开始用漱口液在三餐前后及睡前漱口 ,7次 /d ;术后第 1天用漱口液行口腔护理 ;对照组术前不予漱口液漱口 ,术后第 1天常规用生理盐水棉球行口腔护理。两组于漱口前及术后第 1天分别行咽拭子培养。结果对照组与观察组术后咽试子培养结果比较 ,差异有显著性意义 (均P <0 .0 5 )。呼吸道感染、咳嗽咳痰发生率及其症状持续时间 ,观察组明显低于对照组 (均P <0 .0 1)。结论全麻患者术前采用漱口液漱口 ,可起到局部抑菌杀菌的作用 ,减少呼吸道感染的机会。

Clinical Observation on the Effect of Preoperative Mouth-rinsing on Postoperative Infection of Respiratory Tract After General Anesthesia

Objective To explore the preventive measures for preventing the infection of respiratory tract infection after general anesthesia.Methods Two hundred and forty patients who were to undergo general anesthesia in our hospital were randomized into 2 groups: control group and experimental group, with 120 subjects in each group. Patients in the experimental group were asked to rinse their mouth before and after each meal (three meals a day, 7 times each day). On the first day after the operations, the mouth was cleaned with gargle in nursing care. In the control group, patients did not rinse the mouth before the operation and on the first day after the operations, the mouth was cleaned with gargle in nursing care. Nasopharyngeal cultures were performed before each rising and on the first day of the operation. Results There was a significant difference in the incidence of respiratory tract infection between the two groups (all P<0.05). The incidences and lasting time of cough and sputum-coughing in experimental group were significantly lower than those in control group (all P<0.01).Conclusion Preoprative mouth-rinsing has bacteria inhibitory and bactericidal effects in the patients undergoing general anesthesia, thereby minimizing the opportunity of respiratory tract infection.
