成人心血管手术中病人压疮危险因素的研究

目的 确定心血管手术中病人压疮危险因素，为预防压疮提供临床依据。方法采用便利抽样方法，应用自行设计心血管手术中病人压疮危险因素评估表对2690例心血管手术中病人进行回顾性调查。通过Logistic多元相关分析得出心血管手术病人发生压疮的危险因素。结果年龄、性别、体外循环时间、淋巴细胞计数等4个因素与术中病人发生压疮密切相关，差异具有统计学意义（P〈0．05）。结论年龄增长、男性、体外循环时间长及淋巴细胞计数减少会增加病人术中发生压疮的几率。

The risk factors of pressure ulcer in adult patients undergoing cardiovascular surgery

Objective To investigate the risk factors of pressure ulcer in adult patients undergoing cardiovascular surgery and provide clinical evidences for the preventing pressure ulcer. Methods 2 690 subjects were recruited by the convenient sampling method and investigated by the self-designed risk factors assessment scale. The data were analyzed by the methods of logistic regression analysis. Results Age, gender, cardiopulmonary bypass time and values of lymphocyte were significantly related to the incidence of pressure ulcer( P < 0. 05). Conclusions The increase of age, the male and the extension of cardiopulmonary bypass time, the reduction of lymphocyte will increase the probability of pressure ulcer.
