Abstract:
Objective:To analyze the efficacy of different doses of esketamine in maintaining general anesthesia in elderly patients undergoing radical resection of esophageal cancer.Methods:A total of 98 elderly patients who underwent radical resection of esophageal cancer and admitted from Jun. 2023 to May. 2025 in Shangqiu First People’s Hospital were selected and divided into Group A ( n=50, 0.25 mg·kg -1·h -1) and Group B ( n=48,0.5 mg·kg -1·h -1) according to the dose of esketamine. The following situations between the two groups were compared: (1) hemodynamics [mean arterial pressure (MAP), heart rate (HR) ] before anesthesia induction (T0), 30 minutes after the start of the operation (T1), and at extubation (T2) ; (2) Stress inflammatory indicators [norepinephrine (NE), C-reactive protein (CRP) ] before the operation and 1 day after the operation; (3) Analgesia status [Dosage of propofol and remifentanil, remedial analgesia rate, and the degree of analgesia was evaluated by visual analogue scale (VAS) 2 hours after the operation]; (4) Postoperative recovery [postoperative eye-opening time, extubation time, anesthesia recovery time, and postoperative recovery quality was evaluated using the Chinese version of the 15-item Quality of Recovery (QoR-15) Scale 1 day after the operation]; (5) Safety. Results:(1) At time T1, MAP of both groups was lower than that at time T0,and at time T2, MAP of group B was higher than that at time T1 ( P<0.05). At times T1 and T2, HR of both groups was lower than that at time T0, and HR of both groups at time T2 was higher than that at time T1 ( P<0.05). At time T1, MAP and HR in group B were lower than those in group A ( P<0.05). (2) The dosages of propofol and remifentanil in group B were lower ( P<0.05) ,while the comparison of remedial analgesia rate and VAS score between the two groups showed P>0.05. (3) One day after the operation,the levels of serum NE and CRP in both groups were higher than those before the operation,while those in group B were even lower ( P<0.05). (4) The incidence of adverse reactions in group B (20.83%) was slightly higher than that in group A (10.00%). (5) The eye-opening time,extubation time and anesthesia recovery time after surgery in group B were all longer than those in group A ( P<0.05), while the comparison of QoR-15 scores between the two groups showed P>0.05. Conclusions:In the maintenance of general anesthesia for elderly patients undergoing radical resection of esophageal cancer, the intraoperative hemodynamic fluctuations of low-dose esketamine are smaller. Although the dosages of propofol and remifentanil are higher and the postoperative recovery time is longer, there are no significant differences in analgesic effect, adverse reactions or recovery quality, while the stress and inflammatory responses of high-dose esketamine are smaller.
