在监护室内院内感染的发病率较高,除了泌尿系统感染外,医源性肺炎是最常见的院内感染。常见的院内感染还有伤口感染及败血症。曾有学者报道医源性肺炎的发病率为7%～40%。医源性肺炎在监护室内已成为发病率及死亡率最高的原因,且给临床治疗带来了很大的额外经济负担,而成为一个严重问题。 The incidence of nosocomial infections in the superintendent’s hospital is high, with iatrogenic pneumonia being the most common nosocomial infection in addition to urinary tract infections. Common nosocomial infections are wound infections and sepsis. Some scholars have reported that the incidence of iatrogenic pneumonia was 7% to 40%. Iatrogenic pneumonia has become the leading cause of morbidity and mortality in the care unit and poses a significant additional financial burden on clinical treatment, which has become a serious problem.
