不同年龄急性主动脉夹层患者发病时间的比较

目的比较不同年龄的急性主动脉夹层(acute aortic dissection,AAD)患者的发病时间,以期为因人、因时施护提供客观依据。方法回顾性分析2002年1月至2011年12月在扬州大学临床医学院确诊治疗的、有明确发病时间记载的287例AAD患者的临床资料。根据患者的年龄分为中青年组(65岁)和老年组(≥65岁),对其发病时间进行圆形分布图分析。结果中青年组AAD患者发病存在明显的月份集中趋势,集中月份在9月29日至次年2月18日,高峰月在12月9日;同时存在明显的时间集中趋势,集中时间在6:49至16:19,高峰时间在11:34。老年组AAD患者发病无月份集中趋势,发病呈均匀分布,但存在明显的时间集中趋势,集中时间在6:06至14:43,高峰时间在10:25。不同年龄组患者的发病时间的差异有统计学意义(F=6.197,P0.05)。结论中青年AAD患者的发病时间与老年患者不同,防治侧重不一样,有针对性地做好中青年与老年患者的时间护理,有助于更好地防范AAD的发生。

Comparision of Temporal Pattern of Onset and Nursing of Acute Aortic Dissection in Young and Elderly Patients

Objective To compare the occurrence regularity of acute aortic dissection（AAD） in young and elderly patients, so as to provide the scientific evidences for the personal and time nursing. Methods Clinical data of 287 patients with AAD from January 2002 to December 2011 were analyzed by circu- lar distribution retrospectively, and patients were divided into young group （〈 65 years） and elderly group （≥ 65 years ） according to the sequence of admission. Results AAD often occurred from Sep- tember 29th to next February 18th in young group, the peak is in December 9th. There was also a very obvious hourly centralized tendency, from 6：49 to 16：19 with a peak at 11：34. But there is no monthly but a hourly centralized tendency, from 6.06 to 14：43 with a peak at 10 =25. Significant hourly variation of on- set with different ages was proved （F=6. 1970, P〈 0.05）. Conclusion The onset of AAD has a marked differences for patients with different ages, so we should do time nursing with different strategies to pre- vent ADD.
