The Effect Of Preoperative Short-term Mindfulness Meditation On Preoperative Sedation And Postoperative Anxiety In Patients Undergoing Gynecological Tumor Surgery

Objective:To explore the effects of preoperative short-term mindfulness psychological intervention on preoperative sedation and postoperative anxiety of patients undergoing gynecological tumor surgery.Methods: A total of 60 patients aged 18-60 and classified as ASA I-II who underwent elective surgery for gynecological tumors in our hospital were randomly divided into an experimental group(n=30)and a control group(n=30).One day before the operation,the anesthesiologist made a preoperative visit to the two groups of patients.The State-Trait Anxiety Inventory(STAI)was used to evaluate the patients' state anxiety at baseline,and the Mini-Mental State Examination(MMSE)was used to evaluate the patients' cognitive function at baseline.Patients in the control group received only routine preoperative visits,while patients in the experimental group received a 15-minute mindfulness meditation training in the ward at 7 p.m.one day before the operation,in addition to routine preoperative visits,and filled in the immediate satisfaction questionnaire after the intervention.On the day of the operation,after being connected with standard monitoring and the Bispectral index(BIS)and venipuncture,patients in the control group laid still for 15 minutes,and patients in the experimental group underwent 15 minutes of mindfulness meditation training under professional audio guidance.The blood pressure(BP)and heart rate(HR)before and after the intervention and the BIS value during the intervention were recorded.Numerical Rating Scale(NRS)was used to evaluate the pain degree at four time point: recovery from anesthesia,6h,24 h and 48 h after surgery.Two days after the operation,STAI and MMSE were used to evaluate the postoperative anxiety and cognitive function,and the postoperative satisfaction of the patients in the experimental group was investigated.Results: There was no significant difference in systolic blood pressure and heart rate between the two groups before intervention after entering the operating room(p>0.05).After intervention,systolic blood pressure and heart rate in the experimental group were significantly lower than those in the control group(p<0.05).The BIS value in the experimental group was significantly lower than that in the control group(P<0.05).There was no significant difference in SAI score between the two groups on the first day before the operation(p>0.05),and 48 h after the operation,the SAI score in the test group was significantly lower than that in the control group(p<0.05).There was no difference in TAI scores between the two groups at 1 day before surgery and48 h after surgery(p>0.05).There was no difference in MMSE score between the two groups at 1 day before surgery and 48 h after surgery(p>0.05),and MMSE score did not decrease after surgery.There was no difference in the degree of postoperative pain between the two groups(p>0.05),and the most intense postoperative pain occurred between anesthesia recovery and 6h after surgery.There was no difference in total hospital stay and postoperative hospital stay between the two groups(p>0.05).Both immediate satisfaction and postoperative satisfaction were high in the experimental group.Conclusion: Preoperative short-term mindfulness psychological intervention can effectively stabilize patients' BP and HR before anesthesia,improve the sedation level of patients before anesthesia,and relieve postoperative state anxiety.The satisfaction and acceptability of patients were high.The application of preoperative short-term mindfulness psychological intervention to gynecological tumor surgery patients has certain clinical significance,and can be easily operated.It is a valuable psychological intervention tool which can be applied to clinical work.
