Abstract:
Objective To evaluate the correlation between the concentrations of matrix metalloproteinase-9 (MMP-9) and adiponectin (ADP) and postoperative delirium (POD) in perioperative serum of elderly patients undergoing lobectomy. Methods Seventy-three elderly patients undergoing lobectomy under general anesthesia, 38 males and 35 females, aged 65-80 years, BMI ＜ 24 kg/m2, falling into ASA physical status Ⅰ or Ⅱ, were selected in some suitable period. All patients were divided into POD group and non-POD group according to the Chinese Version of Consciousness Assessment Scale at 24 hours, 48 hours, and 72 hours after operation, and their blood samples were collected 5 minutes before induction of anesthesia (T0), at the time of tracheal extubation (T1) and at postoperative 24 hours (T2), 48 hours (T3), and 72 hours (T4) to determine the concentrations of MMP-9 and ADP in their serums. Results POD occurred in 19 patients, with the incidence rate of 17.8％. The concentrations of MMP-9 at T1-T4 were significantly higher than those before lobectomy in serums in POD group, while the concentrations of ADP in serums were significantly lower than those before lobectomy (P ＜ 0.05). The concentrations of MMP-9 in serums at T1 were significantly higher than those before lobectomy in non-POD group, while the concentrations of ADP in serums were significantly lower than those before lobectomy (P ＜ 0.05). In the comparison between the two groups, the concentrations of MMP-9 in POD group at T1-T4 were significantly higher than those in non-POD group, while the concentrations of ADP in POD group were significantly lower than those in non-POD group (P ＜ 0.05). Conclusion The serum level of MMP-9 is increased and ADP is decreased in perioperative, wich maybe involved in the pathophysiological process of POD in elderly patients undergoing lobectomy.
