摘要: Objective To investigate the effect of permissible hypercapnia (PHY) on postoperative delirium (POD) in elderly patients undergoing thoracoscopic radical resection of esophageal cancer. Methods A total of 92 elderly patients (≥65 years old) who underwent thoracoscopic radical resection of esophageal cancer were randomly divided into the normal arterial partial pressure of carbon dioxide [p(CO2) was controlled at 35-45 mmHg] group (N group, 46 cases) and the mild PHY [p(CO2) was controlled at 46-55 mmHg] group (H group, 46 cases). Data of mean arterial pressure (MAP), heart rate (HR) and cerebral oxygen saturation (rSO2) were recorded when patients were awake (T0), intubated (T1), pneumothorax 0.5 h (T2), pneumothorax 1 h (T3) and vented for 10 min (T4). Intraoperative fluid volume, urine volume, blood loss and ephedrine dosage were recorded in the two groups of patients. Visual analogue scale (VAS) was recorded for three consecutive days after operation, and the occurrence of POD was assessed by Delirium Diagnostic Scale (CAM). Results Compared with T0, MAP, HR and rSO2 were decreased at T1-T4 in the N group and the H group (P<0.05). Compared with the group N, MAP and rSO2 were higher at T2-T4 in the group H (P<0.05). Correlation analysis showed that rSO2 was positively correlated with p(CO2) at T2-T4 in the two groups of patients (rs=0.438, 0.646 and 0.554, all P<0.01). There were no significant differences in infusion volume, urine volume and blood loss between the two groups of patients (P>0.05). Compared with the group N, the amount of ephedrine was lower in the group H [(5.8±3.2) mg vs. (4.0±2.5) mg, t=3.014, P<0.01]. The VAS score were gradually decreased 3 days after operation in the two groups (P<0.05), and there was no significant difference in VAS scores between the two groups (P>0.05). Compared with the group N, the incidence of POD was lower in the group H (8.7% vs. 23.9%, χ2=3.903, P<0.05). Conclusion PHY ventilation strategy in elderly patients undergoing thoracoscopic radical resection of esophageal cancer is helpful to optimize the balance of cerebral oxygen supply and demand, increase rSO2, and reduce the incidence of POD.
