These anesthetic adjuvant drugs did not show significant differences in preventing POCD on postoperative days 1 and 7 compared with each other, but ulinastatin may be more effective in preventing POCD than dexmedetomidine [odds ratio (OR)\u00a0=\u00a00.28, 95% confidence interval (CI)\u00a0=\u00a0(0.10, 0.71)] and parecoxib [OR\u00a0=\u00a00.3, 95% CI\u00a0=\u00a0(0.10, 0.82 on postoperative day 3.
