Task: Question Generation
Input (English): To evaluate whether the use of intraoperative dexmedetomidine (DEX) during lung cancer surgery may reduce the incidence of postoperative atrial fibrillation (POAF).', 'A retrospective study.', 'Academic hospital.', 'Seven hundred three adult patients with non-small-cell lung cancer.', "Patients younger than 18 years of age with a history of atrial fibrillation were excluded. Episodes of atrial fibrillation were identified from electronic medical records and consisted of cardiology consultations, electrocardiogram records, and use of anti-arrhythmic medications within the postoperative admission time. The Wilcoxon rank sum test was used to evaluate the difference in a continuous variable between patient groups. Fisher's exact test or the chi-square test was used to evaluate the association between 2 categorical variables. Logistic regression models were used for multivariate analysis. Overall POAF incidence was 136 of 703 (19.35%), with a mean onset of 3.01±2.03 days after surgery. Among patients, 204 (29.02%) received DEX intraoperatively. Male gender and age were strong predictors of POAF. POAF incidence was comparable between patients who were (n=93, 21.1%) and were not (n=43, 18.6%) treated with DEX (p=0.46). The mean onset time of arrhythmia was similar in both groups (DEX users: 2.93±2.49 days; non-DEX users: 3.05±1.79 days; p=0.146).
Output (English): Does dexmedetomidine reduce atrial fibrillation after lung cancer surgery?
