Clinical analysis of postoperative delirium after endoscopic surgery in patients with benign prostatic hyperplasia / 中华老年医学杂志

ABSTRACT

Objective To prevent the occurrence of postoperative delirium after endoscopic surgery in patients with benign prostatic hyperplasia (BPH). Methods A total of 370 BPH patients receiving endoscopic surgery in our hospital were involved in this study. The clinical parameters including age, other systemic diseases, operation method, operation time and postoperative pain were investigated as predictive risk factors. Then the data were dealt by χ~2 test, single factor analysis or multivariate logistic regression analysis. Results Postoperative delirium occurred in 19 cases (5. 1%). Univariate analysis demonstrated that many factors were significantly correlated with the postoperative delirium in elderly patients, such as age (χ~2 = 7. 37, P<0. 05), other systemic diseases (χ~2=10.26, P<0.05), operation time (χ~2 = 19. 87, P<0.05) and postoperative pain (χ~2= 4.99, P<0. 05). The multivariate logistic regression analysis showed that age (OR = 5. 38, P< 0.05), other systemic diseases (OR = 4. 97, P<0. 05) and operation time (OR = 6. 53, P<0. 05) were important factors for postoperative delirium. Conclusions Paying more attention to the advanced age, giving sufficient preoperative preparation and reducing operation time may help to prevent postoperative delirium.
