Objective To investigate the efficacy of active silver ion antibacterial solution on oral pharynx before tracheal intubation in general anesthesia. Methods One hundred cases of tracheal intubation with general anesthesia for cholecystectomy were selected. The patients were divided into observation group and control group, with 50 cases in each group. The observation group was treated with active silver ion antibacterial liquid and the control group with physiological saline. Throat swabs were collected for semi-quantitative culture of bacteria. The data of semi quantitative culture and different bacterial species were compared between the 2 groups and the pain of the mouth and pharynx was observed. Results The bacteria in semi quantitative culture from the samples from the observation group were less than those from the control group(P<0.001).Gram positive cocci and gram negative bacilli in the observation group were less than those in the control group(P<0.05). The pain score after tracheal extubation of the observation group was lower than that of the control group (P<0.05). Conclusion Active silver ion antibacterial liquid before tracheal intubation in general anesthesia can effectively reduce bacterial colonization in oropharynx, prevent respiratory tract infection, and alleviate postoperative oropharyngeal pain.%目的 探讨全麻手术气管插管前使用活性银离子抗菌液对患者口咽部处理的应用效果.方法 选取行胆囊切除术全麻气管插管手术患者100例.采用随机数字表法将患者分为观察组和对照组各50例.观察组应用活性银离子抗菌液进行口咽部预防处理,对照组应用生理盐水处理.采集口咽部拭子进行2组细菌半定量、不同细菌种类的比较,并观察口咽部疼痛情况.结果 采集的标本细菌培养半定量观察组低于对照组(P<0.001),观察组的革兰氏阳性球菌与革兰氏阴性杆菌量较对照组低(P<0.05),气管插管拔除后观察组疼痛评分低于对照组(P<0.05).结论 在全麻手术气管插管前应用活性银离子抗菌液能有效减少患者口咽部细菌定植,预防呼吸道感染的发生,可有效降低患者术后口咽部疼痛感.
