Objective To investigate influencing factors of postoperative cognitive dysfunction (POCD) in elderly patients underwent laparoscopic surgery. Methods The elderly patients underwent laparoscopic surgery were collected in the Daye City People's Hospital and Yangxin County People's Hospital from September 14, 2014 to January 1, 2016 and the Traditional Chinese Medicine Hospital of Daye City from June 19, 2014 to January 1, 2016. Factors included in the registration of patients in general and a variety of influencing factors during perioperative period were recorded. The independent factors associated with POCD were analyzed by multivariate logistic regression analysis. Results Three hundred and seventy-eight elderly patients underwent laparoscopic surgery were included according to the inclusion and exclusion criteria, of which 43 patients with POCD and 335 patients without POCD within 3 days after laparoscopic surgery. The baseline data had no significant differences between the patients with POCD and without POCD. The cerebral infarction, preoperative fear, preemptive analgesia, use of dexmedetomidine before laparoscopic surgery, general anesthesia combined with epidural anesthesia, operation time, low SpO2 during anesthesia induction, PaCO2 after pneumoperitoneum, postoperative patient controlled epidural analgesia (PCEA), postoperative VAS score on day 3 were associated with the POCD (P < 0.05). The results of logistic regression analysis showed that the preemptive analgesia, use of dexmedetomidine before laparoscopic surgery, general anesthesia combined with epidural anesthesia, and postoperative PCEA were the independent protective factors of the POCD (P < 0.05). The operation time and PaCO2 after pneumoperitoneum were the independent risk factors of the POCD (P < 0.05). Conclusion For elderly patients underwent laparoscopic surgery, clinicians should be alert to occurrence of POCD according to the influence factors of it, and timely screen relevant scale so as to early diagnose and early intervent and effectively delay progress of patient's POCD.
