Related factors of delirium after transsphenoidal endoscopic pituitary adenoma resection-A matched retrospective...

The primary aim of this study is to explore the factors associated with delirium incidence in postoperative patients who have undergone endoscopic transsphenoidal approach surgery for pituitary adenoma.

The study population included patients admitted to Tianjin Huanhu Hospital's Skull Base Endoscopy Center from January to December 2022, selected through a retrospective cohort study design. The presence of perioperative delirium was evaluated using the 4 'A's Test (4AT) scale, and the final diagnosis of delirium was determined by clinicians. Statistical analysis included Propensity Score Matching (PSM), χ2 Test, and Binary Logistic Regression.

A total of 213 patients were included in this study, and the incidence of delirium was found to be 29.58 % (63/213). Among them, 126 patients were selected using PSM (delirium:non-delirium = 1:1), ensuring age, gender, and pathology were matched. According to the results of univariate analysis conducted on multiple variables, The binary logistic regression indicated that a history of alcoholism (OR = 6.89, [1.60-29.68], P = 0.010), preoperative optic nerve compression symptoms (OR = 4.30, [1.46-12.65], P = 0.008), operation time ≥3 h (OR = 5.50, [2.01-15.06], P = 0.001), benzodiazepines for sedation (OR = 3.94, [1.40-11.13], P = 0.010), sleep disorder (OR = 3.86, [1.40-10.66], P = 0.009), and physical restraint (OR = 4.53, [1.64-12.53], P = 0.004) as independent risk factors for postoperative delirium following pituitary adenoma surgery.

For pituitary adenoma patients with a history of alcoholism and presenting symptoms of optic nerve compression, as well as an operation time ≥3 h, enhancing communication between healthcare providers and patients, improving perioperative sleep quality, and reducing physical restraint may help decrease the incidence of postoperative delirium.
