ABSTRACT
Objective To analyze the associated factors of ICU delirium after cardiac surgery,and propose the proper treatment strategy.Methods 124 patients after cardiac surgery were observed.The basic information including gender,age,blood type,respirator assistant time and ICU hospitalizing time was recorded.SPSS software was used for statistical analysis.Results Among the 124 patients,the incidence of ICU delirium was 17％.There was significant difference between patients with ICU delirium and without ICU delirium on age,respirator assistant time and ICU hospitalizing time.The ICU delirium incidence was dramatically different among different blood types,and the incidence of blood type A was much more higher than blood type B and O.Univariate Logistic regression analysis showed that age,mechanical ventilation time,ICU time,gender and blood types were the related factors of delirium in ICU.Conclusions Age,respirator assistant time,ICU hospitalizing time,and blood type are all influencing factors of ICU delirium.Patients who are male,older,or with longer usage of respirator,or with longer ICU hospitalizing time are more likely to develop ICU delirium.The incidence of ICU delirium is quite different among different blood types,blood type A is more easily to occur ICU delirium than blood type O and B.
