Effects of Different Doses of Esketamine on Postoperative Anxiety and Depression in Patients with Breast Cancer
Objective To investigate the effect of different doses of esketamine on postoperative anxiety and depression in patients with breast cancer.Methods A total of 96 patients undergoing modified radical mastectomy were randomly divided into esketamine L group(0.15mg/kg),M group(0.30mg/kg),high-dose H group(0.50mg/kg),and normal saline group(C group)with 24 cases in each group which will be given during induction of anesthesia.State Anxiety Scale(SAI)score and Montgomery Depression Scale(MADRS)score were recorded 1day before surgery(D1),1day after surgery(D2),3days after surgery(D3),5days after surgery(D4),and 7days after surgery(D5).Data such as the dosage of remifentanil,the dosage of norepinephrine,and the duration of the op-eration(from the beginning of the operation to the end of the operation)were recorded during the operation.The time from the end of an-esthesia to extubation and the postoperative PACU residence time was recorded,and delirium,postoperative nausea and vomiting(PONV),dizziness,drowsiness,and pain relief rate within 24hours after surgery were recorded.Results At D3,group H had a lower SAI score than the other three groups(P＜0.05);compared with D1,the SAI score at D4 and D5 in groups C,L,and M was signifi-cantly decreased(P＜0.05).The SAI score of group H at D3,D4,and D5 was decreased(P＜0.05);the MADRS score of group H was lower than that of the other three groups at D3 and D4(P＜0.05);compared with D1,the MADRS score of all groups gradually de-creased with the extension of time(P＜0.05).Remifentanil consumption in group H was significantly lower than that in the other three groups(P＜0.05).There were no significant differences in the incidence of postoperative delirium,PONA,remedial analgesia,dizzi-ness,lethargy,and fever among the four groups(P＞0.05).Conclusion Intraoperative intravenous injection of esketamine can reduce the SAI and MADRS scores,reduce the perioperative opioid consumption,and not increase the incidence of postoperative adverse reac-tions in breast cancer patients.
