目的：探讨休克病人发生压力性损伤（PI）的危险因素，为建立适用于休克病人的PI评估工具提供依据。方法：回顾我院重症医学科（ICU）2016年1月至12月收治的休克病人的资料，从临床信息系统（CIS）中提取病人一般资料、入住ICU 24 h的Braden PI危险因素评估量表的各因素评分，以及相应时间段PI危险因素调查表中各条目信息，查看护理记录单及PI上报系统，收集是否带入PI和停用血管活性药1周内有无新发PI等数据。将各因素进行PI发生危险因素的单因素方差分析和多因素Logistic回归分析。结果：共纳入休克病人448例，发生PI 169例（37.72%）。多因素Logistic回归分析显示，急性生理与慢性健康评价Ⅱ评分、ICU住院时间、大体皮肤情况、使用血管活性药是休克病人发生PI的独立危险因素。结论：休克病人发生PI是多种危险因素共同作用的结果，仅仅使用Braden量表评估休克病人PI的危险性不能满足临床的需求。
