- Abstract: BACKGROUND:As a routine method after lumbar spine surgery,a drainage tube is convenient for postoperative bleeding drainage and management,and there is still no consensus on the choice of postoperative removal time for short-segment lumbar spine surgery with less risk. OBJECTIVE:To explore the effect of different drainage times on early clinical efficacy after short-segment lumbar fusion. METHODS:A prospective randomized controlled study was performed on 220 patients in the Affiliated Hospital of Southwest Medical University who underwent posterior lumbar interbody fusion for lumbar degenerative diseases from March 2017 to April 2021.According to the different drainage times,the patients were randomly divided into removal on the second day after operation(group A),removal on the third day after operation(group B),and removal after the observation method 24-hour drainage volume<30 mL(group C).The perioperative indicators and follow-up results of the three groups of patients were observed and compared. RESULTS AND CONCLUSION:(1)Because 7 patients were lost to follow-up,2 patients were excluded,and 211 patients were finally included(72 patients in group A,71 patients in group B,and 68 patients in group C).(2)The average drainage time of group C was 2.91 days.The postoperative drainage volume in group A was significantly less than that in groups B and C,and the difference was statistically significant(P<0.05).On day 3 after operation,the hematocrit value of group C was lower than that of group A and group B,and the difference was statistically significant(P<0.05).Postoperative activity time and hospital stay in group A were shorter than those in groups B and C,and the difference was statistically significant(P<0.05).(3)Four patients in group A,two patients in group B and three patients in group C received an allogeneic blood transfusion.There was no significant difference among the groups(P>0.05).(4)In terms of postoperative complications,there were no statistical differences in postoperative wound leakage and surgical site infection in all three groups(P>0.05).(5)All patients were followed up for more than 12 months.Visual analog scale score and Oswestry dysfunction index of the three groups of patients before discharge and at the last follow-up were significantly improved compared with those before surgery(P<0.05).There was no statistical significance among the groups(P>0.05).(6)It is indicated that the removal of the drainage tube on the second day after a posterior lumbar fusion can effectively reduce the time to get out of bed and hospital stay,without increasing the postoperative blood loss and the risk of complications.
