目的：观察和分析口腔护理干预对危重住院患者口腔感染的控制效果。方法选取200例危重住院患者作为研究对象，将其随机分为观察组和对照组，每组各100例。观察组患者应用2.5%碳酸氢钠溶液擦拭进行口腔护理干预，对照组患者给予常规口腔护理。对两组患者护理干预后1、2周的口腔感染发生率、护理干预前、后的口腔评分和pH值进行观察和比较。结果观察组患者干预后1周和2周的口腔感染发生率均低于对照组（χ2=5.838、7.447，P＜0.05）；护理干预后观察组患者干预后的口腔评分低于对照组，口腔pH值高于对照组（t=8.000、11.300，P＜0.05）。结论在危重患者的护理中，应用碳酸氢钠液擦拭进行口腔护理干预，能够有效降低危重患者的口腔感染发生率，改善口腔症状和口腔环境。%Objective To observe and analyze the effects of oral nursing intervention in the control of oral infection of critical patients.Methods 200 cases of hospitalized critical patients were selected as the research objects and randomly divided into the observation group and the control group. 100 cases were included into each group. The patients in the observation group was treated with wiping of 2.5%, sodium bicarbonate solution for the oral nursing intervention, the patients in the control group were treated with routine oral nursing. The incidences of oral infection in 1 and 2 week after nursing intervention, the oral scores and pH values before and after the nursing intervention of the patients in the two groups were observed and compared.Results The incidences of oral infection in 1 and 2 week after nursing intervention rate of the patients in the observation group were lower than those in the control group (χ2=5.838, 7.447,P<0.05), after nursing intervention, the oral score of the patients in the observation group was significantly lower than that in the control group, the pH value was signiifcantly higher than that in the control group (t=8.000,11.300,P<0.05). Conclusion In nursing care of critical patients, the application of wiping of sodium bicarbonate solution for oral nursing intervention can effectively reduce the incidence of oral infection of critical patients, improve the symptoms of oral and oral environment.
