Application Of Enhanced Recovery After Surgery In Perioperative Period Of Lumbar Spinal Stenosis

Objective: To evaluate the effectiveness and value of the application of enhanced recovery after surgery(ERAS)in the perioperative period of lumbar spinal stenosis,and to help further optimize the management in the later stage.Methods: Retrospective analysis was used to study the clinical data of 40 patients who were diagnosed with lumbar spinal stenosis and underwent surgical treatment in our department.The control group selected 20 patients from November2018 to April 2019 and given conventional treatment methods.The ERAS group selected 20 patients from April 2019 to October 2019,and adopted the perioperative method optimized by the ERAS concept.Gender,age,weight,operation time,Preoperative visual analog scale(VAS),Visual analog scale(VAS)for the first 3 days after surgery,Intraoperative blood loss,total postoperative drainage,postoperative first exhaust time,postoperative hospital stay,postoperative nausea and vomiting and other complications of the two groups were collected.All data were processed using SPSS26.0 statistical software.Counting data were tested by chi-square.The measurement data are analyzed normally.Normally distributed data were expressed by mean±standard deviation(?x ± s),and independent sample t-test was adopted.Non-normally distributed data are expressed as median and interquartile range,and comparisons between groups were performed using the Mann-Whitney U test.P <0.05 can be considered statistically significant between groups.Results:(1)There was no significant difference in age,weight and gender between the two groups of patients(P>0.05).(2)There was no significant difference between the two groups of patients before and after surgery on the 1st day(Z=-0.973,-0.116,P>0.05).The pain scores in the ERAS group were lower than those in the control group on the 2nd and 3rd day after operation,and the difference was statistically significant.(Z=-4.302,-3.028,P<0.05).(3)Comparison of intraoperative blood loss between the two groups was statistically significant(Z=-2.025,P<0.05).There was no statistical significance in the operation time and postoperative drainage(Z=-0.898,-1.234,P>0.05).(4)There was no significant difference in the first exhaust time and hospital stay between the two groups ofpatients(t=-1.340,-1.060,P>0.05).(5)There was no significant difference in the incidence of postoperative complications between the two groups of patients(P>0.05).Conclusion: The application of the ERAS in the perioperative period of lumbar spinal stenosis can reduce the amount of bleeding during surgery and effectively relieve pain after surgery,without increasing the incidence of postoperative complications and improving the quality of life during the perioperative period..With more understanding of the ERAS,it may be necessary to adjust and supplement the current relevant treatment measures.
