Effects of esketamine on postoperative anxiety and depression in burn patients undergoing escharec-tomy and skin grafting
Objective To investigate the effects of intraoperative application of esketamine on post-operative anxiety and depression in burn patients undergoing escharectomy and skin grafting.Methods Seventy-three patients undergoing escharectomy and skin grafting were selected,46 males and 27 females,aged 18-64 years,BMI 18.5-27.9 kg/m2,ASA physical status Ⅱ or Ⅲ.According to the random number table method,the patients were divided into two groups:esketamine group(group E,n=37)and control group(group C,n=36).Group E received a 0.2 mg/kg intravenous bolus of esketamine during anesthesia induction followed by a 0.1 mg·kg-1·h-1 continuous infusion until the end of surgery.Group C received an equal volume of normal saline.Patients in both groups received patient-controlled intravenous analgesia(PCIA)after surgery.The postoperative eye opening time,extubation time,PACU residence time,hospitalization and the number of effective compressions and total compressions of postoperative anal-gesia pumpand remediate analgesia after surgery were recorded.The self-rating anxiety scale(SAS),self-rating depression scale(SDS)and incidence of anxiety and depression were recorded 1 day before surgery,3 and 7 days after surgery.The occurrence of adverse reactions within 48 hours after surgery were also recor-ded.Results Compared with group C,the postoperative PACU residence time and hospitalization in group E were shortened(P＜0.05),the times of effective and total compressions and remediate analgesia after surgery in group E were decreased(P＜0.05),the scores of SAS and SDS and incidence of anxiety and depression at 3 and 7 days after surgery in group E were decreased(P＜0.05).There were no statistical differences in adverse reactions within 48 hours after surgery between the two groups.Conclusion Intraop-erative application of esketamine in burn patients undergoing escharectomy and skin grafting can improve postoperative anxiety and depression,reduce the usage of postoperative opioids and promote early recovery.
