Abstract

Abstract:

Objective To analyze the risk factors for stroke-associated pneumonia. Methods The patients with acute ischemic stroke (AIS) who were consecutively admitted to Beijing Tiantan Hospital from May 2014 to May 2016 were included in this retrospective study. According to whether they developed new-onset pneumonia within 7 days of stroke onset, all the patients were divided into stroke-associated pneumonia group and non-pneumonia group. The vascular risk factors and NIHSS at admission were compared between the two groups, and multivariate logistic regression analysis was used to analyze the risk factors for stroke-associated pneumonia. Results A total of 1129 patients were included, including 1043 patients in non-pneumonia group and 86 patients in stroke-associated pneumonia group. Multivariate analysis showed that elder age (OR 1.084, 95%CI 1.047-1.122, P <0.0001), NIHSS at admission (OR 1.192, 95%CI 1.133-1.254, P <0.0001), increased white blood cells count (OR 1.269, 95%CI 1.134-1.420, P <0.0001) and long hospital stay (OR 1.146, 95%CI 1.087-1.208, P <0.0001) were independent risk factors for strokeassociated pneumonia. Conclusions Acute ischemic stroke-associated pneumonia were associated with elder age, severe neurological impairment, increased white blood cells count and long hospital stay.

摘要：

目的分析缺血性卒中相关性肺炎危险因素。方法连续入组2014年5月-2016年5月收治的急性缺血性卒中患者为研究对象，根据是否在卒中发病7 d内新发生肺炎将患者分为无卒中相关性肺炎组与卒中相关性肺炎组，比较两组患者的血管危险因素、入院NIHSS等指标的差异，并采用多因素logistic回归分析卒中相关性肺炎的独立影响因素。结果研究共入组1129例急性缺血性卒中患者，无卒中相关性肺炎组1043例，卒中相关性肺炎组86 例。多因素分析显示，年龄增高（OR 1.084，95%CI 1.047～1.122，P <0.0001）、入院NIHSS评分增加（OR 1.192，95%CI 1.133～1.254，P <0.0001）、白细胞计数升高（OR 1.269，95%CI 1.134～1.420，P <0.0001）及住院天数延长（OR 1.146，95%CI 1.087～1.208，P <0.0001）是卒中相关性肺炎的独立危险因素。结论缺血性卒中后卒中相关性肺炎的发生与高龄、神经功能缺损程度重、白细胞增高、住院时间长有关。

者出现吞咽功能障碍[14]，提示缺血性卒中患者

发病后早期发生肺炎的风险即开始上升。本研

究显示缺血性卒中发病至肺炎确诊中位时间为

4 d，累计50%发病时间范围为0～3 d。结合卒

中相关性肺炎组入院白细胞计数已经明显升高，

提示缺血性卒中患者发病4 d内是卒中相关性

肺炎的高发时间段。因此，对缺血性卒中患者

进行早期肺炎危险因素评估，进而制订针对性

的治疗和护理方案，具有重要的临床意义。

本研究为横断面研究，对连续的住院患者

进行数据分析，样本量较大，因此结果具有一

定的代表性。卒中相关性肺炎的风险也同时受

医院对卒中患者临床治疗的规范性的影响，如

本研究的中心常规对卒中患者进行入院后早期

的吞咽功能筛查并针对吞咽障碍的患者进行

治疗和干预，这些管理和诊疗措施均可能影响

卒中相关性肺炎的发生率，因此本研究作为在

单中心展开的调查分析，结果可能具有一定的

偏倚。不过基于本研究的结果数据，提示临床

医师应该对高龄、神经功能缺损严重、入院时

白细胞计数增高的患者进行更严格的预防肺炎

的管理，以降低这部分患者卒中相关性肺炎发

生的风险。
