隐匿性肺炎的临床特点分析

Clinical characteristics of occult pneumonia

目的分析与总结隐匿性肺炎的临床特点,为临床诊断及治疗提供依据。方法回顾性分析2008年6月-2012年6月64例隐匿性肺炎住院患者的临床资料,分析其临床发病年龄、季节、首发症状、实验室检查、放射学检查以及治疗等特点,采用SPSS 13.0统计软件处理,计量资料以均数t表示;计数资料的组间比较采用χ2检验。结果流行病方面,男性39例占60.94%,女性25例占39.06%,年龄主要集中在中老年(>40岁)51例占87.89%,发病季节则集中在夏秋两季42例占65.63%,经统计分析,性别、年龄以及发病季节的差异均有统计学意义(P<0.05);临床表现方面,胸痛为最常见的首发症状,35例占54.69%,血白细胞不增高者38例占59.38%,胸部CT检查阳性47例占73.44%,经统计分析,临床表现、血白细胞以及特殊检查的差异均有统计学意义(P<0.01)。结论隐匿性肺炎的发病对象主要系中老年男性患者,发病季节集中在夏秋两季;胸痛为常见的首发症状;白细胞检查多不增高;胸部放射学检查CT明显优于X线,治疗上以针对革兰阴性杆菌的抗菌药物为主。

OBJECTIVE To analyze and summarize the clinical characteristic of occult pneumonia ,so as to provide the basis for clinical diagnosis and treatment .METHODS Retrospectively analyzed the 64 cases of occult pneumonia and its clinical characteristics such as morbidity age ,seasons ,first round symptom ,laboratory inspection ,radio-activity inspection as well as treatment .Using SPSS 13 .0 statistical software processing ,measurement data with mean t ;the count data were compared between the groups using χ2 test .RESULTS In epidemic ,39 males accoun-ted for 60 .94% ,significantly higher than 25 female patients accounting for 39 .06% .The morbidity age central-ized （the ＆gt;40 year） 51 cases accounted for 87 .89% in the middle and old age .Seasonal incidence was concentrat-ed in the summer and fall of 42 cases accounted for 65 .63% .According to statistical analysis ,the differences of genders ,age and seasons were significant （P＆lt;0 .05） .In clinical manifestations ,chest pain of first symptom was the most common ,35 cases accounting for 54 .69% ;white blood cell was not increased ,38 cases accounting for 59 .38% ;the positive rate of chest CT checking was 47 cases ,accounting for 73 .44% ;according to statistical analysis ,the differences of clinical manifestations ,white blood cells and chest CT checking all were significant （P＆lt;0 .01） .CONCLUSION Occult pneumonia mainly occur in middle-aged and elderly men ,and in summer and autumn;chest pain was the most commonly initial symptoms ;check of white blood cell does not increased ;the CT of chest radiology is superior to x-ray in diagnosis ;the choice of antibiotic mainly aims at the gram-negative bacilli .
