卒中相关性肺炎是脑卒中最常见并发症之一,其病菌易产生抗生素耐药性,对患者的肢体和语言等相关功能的恢复产生不利影响,治疗棘手,严重影响患者的预后[1]。有研究表明,脑卒中急性期患者中有约10%~47%发生肺部感染,而死于肺部感染者占脑卒中死亡病例的1/3[2-4]。卒中相关性肺炎是卒中常见的并发症,其发病率为7%~22%[5],其肺部感染的控制程度,影响到卒中患者的转归和 Stroke-associated pneumonia is one of the most common complications of stroke. Its pathogens are susceptible to antibiotic resistance, adversely affecting the recovery of patients’ limbs and language-related functions, and are difficult to treat and seriously affect patient’s prognosis [1]. Studies have shown that about 10% to 47% of patients with acute stroke have pulmonary infection, while those who died of lung infection accounted for 1/3 of stroke deaths [2-4]. Stroke-associated pneumonia is a common complication of stroke and its incidence is 7% -22% [5]. The degree of lung infection control affects the outcome of stroke patients and
