目的 :比较危急重症病人动脉血和静脉血中钾离子结果有无差异.方法 :随机抽取2019年2月 —6月我院重症监护室收治的病人61例,分别采集动脉血和静脉血,采用血气分析仪测定动脉全血钾离子浓度和某公司生产的7600生化分析仪测定静脉血血清中钾离子的浓度,比较两者结果是否有统计学差异及其相关性.结果 :动脉血钾浓度明显低于静脉血钾浓度,差异有统计学意义(t=-5.406,P=0.000).动脉血钾与静脉血钾存在线性相关关系,静脉血钾浓度=1.024+0.783动脉血钾浓度,相关系数r=0.712,P<0.005.结论 :动脉血钾与静脉血钾存在线性相关性,动脉血钾值可代入线性回归方程换算成静脉血钾浓度,作为临床诊治的依据.
Objective:To detect and analyze the infections of respiratory pathogens in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods:Through retrospective analysis, 335 AECOPD patients hospitalized from October 2016 to September 2018 in the First People′s Hospital of Pinghu were selected.The indirect immunofluorescence method was used to detect IgM antibody of eight kinds of respiratory pathogens, and the results were analyzed.Results:The positive rate of respiratory pathogens-IgM antibody in patients with AECOPD was 29.9%.There were 57 cases with one single pathogen infection, 36 cases with two pathogens mixed infection, 7 cases with three kinds of pathogens mixed infection.The influenza virus B [52.0%(78/150)] was the most common, followed by influenza virus A [27.3%(41/150)], the positive rates of pathogens were influenza virus B>influenza virus A>respiratory syncytial virus>parainfluenza virus>Legionella pneumophila>Mycoplasma pneumoniae>Chlamydia pneumoniae>adenovirus.There was no statistically significant difference in different age groups(χ 2=0.047, P=0.829). The positive rates of pathogens-IgM in spring[55.3%(63/114)] and winter[58.1%(54/93)] were higher than those in summer[26.2%(16/61)] and autumn[25.4%(17/67)], the differences were statistically significant(χ 2=30.398, P<0.01). Conclusion:AECOPD is closely related with respiratory pathogens, especially influenza virus.We should do preventive work well in epidemic season.
目的:统计过敏原IgE抗体在3种常见过敏性疾病中的分布情况,为临床诊治提供依据.方法:采用免疫印迹法检测过敏性鼻炎(200例)、哮喘(50例)、皮炎(410例)患者血清吸入性-食物性过敏原特异性IgE抗体,并进行比较分析.结果:660例患者中最常见的过敏原为户尘螨(46.21％)、树花粉(23.48％)、鸡蛋白(21.97％)、牛奶(21.97％)、苋(18.94％).皮炎组狗毛皮屑、牛奶阳性率明显高于鼻炎哮喘组(P＜0.05),鼻炎组的猫毛皮屑阳性率明显高于其他两组(P＜0.05),哮喘组树花粉的阳性率明显高于其他两组(P＜0.05),其他组各病种阳性率差异无统计学意义(P＞0.05).
