The effect of ketamine on the postoperative depression-like mood and inflammatory mediators during one lung ventilation in patients with esophageal cancer radical surgery / 实用医学杂志

ABSTRACT

Objective To observe the effect of ketamine at low dose on inflammatory mediators during one lung ventilation and postoperative depression-like mood in patients with esophageal cancer radical surgery. Methods 60 patients who underwent esophageal cancer radical surgery were randomly divided into ketamine group(K)and control group(C). The patients in group K was injected with ketamine at a dose of 0.5 mg/kg at the time of anesthesia induction,then continuous infused with ketamine at a dose of 0.25 mg/(kg · h)for 30 minutes. Patients in group Csaline was given .Then concentrations of TNF-α,IL-6,IL-10 and PHQ-9 scores at different time points were evaluated. Results The PHQ-9 scores of the patients in K group at the 5 d after operation was significantly lower than that at the 1d before operation(P<0.05);The PHQ-9 scores in group K were decreased ob-viously than that those in group C(P<0.05). The concentration of serum TNF-α,IL-6 and IL-10 were significantly increased after T1 time of the two groups(P<0.05);Compared with group C,there was no statistical difference in the levels of TNF-α,IL-6 and IL-10 in group K at T2 and T3 time(P<0.05).Conclusion Low dose ketamine has no obvious effect on the concentration of blood TNF-α,IL-6 and IL -10 during one lung ventilation in patients with esophageal cancer radical surgery ,but it may alleviate postoperative depression-like mood.
