Postoperative delirium or psychosis occurs in 41% to 70% of patients following open-heart surgery, with predisposing factors including illness severity, physical stress, and environmental circumstances.
The text highlights the high incidence of postoperative delirium or psychosis following open-heart surgery, noting previous estimates ranging from 41% to 70%.
High postoperative delirium rates after open-heart surgery warrant clinical vigilance; leaves optimal prevention strategies open for trials.
A MAIN focus of interest in relation to open-heart surgery has been the reputedly high incidence of delirium or psychosis characterized by perceptual distortion, hallucinations, and paranoid ideation occurring two to five days following surgery. Egerton and Kay¹reported a 41% incidence of postoperative delirium, and Blachly and Starr,²57%. Kornfeld et al³found a similar incidence in reviewing their records, but when they personally interviewed a sample of their patients they raised their estimate of the incidence of postoperative delirium to 70%. Predisposing factors which statistically are more frequent in the patients developing delirium are seriousness of illness preoperatively,²degree of physical stress during surgery,²and environmental circumstances such as marital instability, overwhelming personal problems, and a lack of positive interpersonal support during hospitalization.¹However, there appears to be increasing evidence pointing toward the

Harold Gilberstadt (1967) conducted a review in Open-heart surgery. Open-heart surgery was evaluated on Postoperative delirium or psychosis. Postoperative delirium or psychosis occurs in 41% to 70% of patients following open-heart surgery, with predisposing factors including illness severity, physical stress, and environmental circumstances.
