【摘要】：目的分析自发性气胸发病的时间规律,研究气压、风速等气候因素对自发性气胸发病的影响。方法收集沈阳医学院附属中心医院2011年1月1日至2015年12月31日门诊及住院的自发性气胸门诊及住院患者593例,记录5年间日平均气压及风速数据,分析自发性气胸发病的时间规律及其与大气压、风速变化的关系。结果沈阳地区自发性气胸发病具有明显季节性,原发性自发性气胸每年3、4月份高发,继发性自发性气胸气胸每年11、12月份高发。自发性气胸发病日及前1 d气压差低于非气胸发病日气压差0.6 h Pa,差异有统计学意义(P0.05);自发性气胸发病日风速明显高于非气胸发病日[分别为(9.46±6.33)m/s、(7.11±5.47)m/s,P0.001]。结论自发性气胸发病时间有明显聚集性,大气压急剧下降及风速明显增大对自发性气胸发病具有重要影响。
[Abstract]:Objective to analyze the time rule of spontaneous pneumothorax and to study the influence of climatic factors such as air pressure and wind speed on spontaneous pneumothorax. Methods 593 outpatients and inpatients with spontaneous pneumothorax from January 1, 2011 to December 31, 2015 in affiliated Central Hospital of Shenyang Medical College were collected, and daily mean air pressure and wind speed data were recorded. To analyze the time rule of spontaneous pneumothorax and its relationship with atmospheric pressure and wind speed. Results the incidence of spontaneous pneumothorax in Shenyang was obviously seasonal. The incidence of primary spontaneous pneumothorax was high in April every year, and that of secondary spontaneous pneumothorax was high in November and December each year. The air pressure difference was significantly lower on spontaneous pneumothorax and 1 day before onset than that on non-pneumothorax (P 0.05), and the wind speed on spontaneous pneumothorax was significantly higher than that on non-pneumothorax [(9.46 卤6.33) m / s, (7.11 卤5.47) m / s 路s ~ (0.001), respectively]. Conclusion the onset time of spontaneous pneumothorax has obvious aggregation, the sharp decrease of atmospheric pressure and the obvious increase of wind speed have important influence on the onset of spontaneous pneumothorax.
