Epistaxis is one of the commonest ENT emergencies and is experienced by up to 60% of people in their lifetime, with 6% requiring medical attention. The objective of the study was to determine the frequency of primary epistaxis and its relationship with temperature and relative humidity.
This cross sectional study included 460 patients with epistaxis attending the ENT Department of Ayub Medical College, Abbottabad. Daily temperature and humidity record was obtained from the department of Hydrology and Meteorology of Hazara Division. The results of four hundred and sixty patients were analyzed for the effect of temperature and humidity on the frequency of epistaxis. Data was analysed using SPSS-11. Pearson's r was calculated to determine correlation between different variables.
A total of 460 patients were included, out of which 206 (44.8%) had primary epistaxis. The frequency of primary epistaxis was seen to be higher during the cold period from October to March. Statistical analysis showed good negative correlation between temperature and primary epistaxis (r = -0.948) while average correlation with humidity (r = -0.445).
The relationship between temperature and primary epistaxis was good while that with relative humidity was average.
鼻出血是耳鼻喉科最常见的急症之一，一生中高达60%的人会经历鼻出血，其中6%的人需要就医。本研究的目的是确定原发性鼻出血的发生率及其与温度和相对湿度的关系。
这项横断面研究纳入了460例在阿伯塔巴德阿尤布医学院耳鼻喉科就诊的鼻出血患者。每日温度和湿度记录来自哈扎拉地区水文气象部门。分析了460例患者的结果，以研究温度和湿度对鼻出血发生率的影响。使用SPSS-11对数据进行分析。计算Pearson相关系数r以确定不同变量之间的相关性。
共纳入460例患者，其中206例（44.8%）为原发性鼻出血。原发性鼻出血的发生率在10月至3月的寒冷时期较高。统计分析显示温度与原发性鼻出血之间存在良好的负相关（r = -0.948），而与湿度的相关性一般（r = -0.445）。
温度与原发性鼻出血之间的关系良好，而与相对湿度的关系一般。
