Safety And Clinical Effect Of No Drainage Tube After Lumbar Fusion

Objective:To investigate the safety and clinical efficacy of no drainage tube after lumbar fusion,so as to provide reference for rapid recovery after lumbar fusion.Methods:A retrospective study was conducted on 128 patients accepted lumbar fusion surgery in the same surgery group in our hospital from September 2015 to September 2018.From April 2017 to September 2018,patients who received single or double segment posterior lumbar interbody fusion were set as group A(observation group,without drainage tube)because of no drainage tube after operation.From September 2015 to March 2017,patients who received single or double segment posterior lumbar interbody fusion were set as group B because of drainage tube after operation(control group,drainage tube group).There were 65 patients in group A,including 30 males and 35 females,with an average age of 55.09±5.22,54 cases accepted TLIF and 11 cases accepted PLIF,39 cases accepted single-segment fusion and 26 cases accepted double-segment fusion.There were 63 patients in group B,including 27 males and 36 females,with an average age of 56.71±1.43,48 accepted TLIF and 15 accepted PLIF,37 single segment fusions and 26 double segment fusions.The two groups were compared in terms of operation time,blood loss,postoperative time on the ground,preoperative and postoperative lower back pain at 3 days,1 week,1 month and 1 year after the surgery(VAS score),and spinal function improvement at 1 week,1 month and 1 year after the surgery(ODI score).Postoperative incision complications were recorded in both groups.Results:There was no significant difference in preoperative general data between the two groups(P>0.05).There was no significant difference in operation time between the two groups(P>0.05).The amount of blood loss in group A was less than that in group B(P<0.05),and the postoperative time on the ground in group A(2.88±0.75 days)was earlier than that in group B(P<0.05).VAS score and ODI score of each time period after the operation of the two groups were significantly different from those before the operation(P<0.05),and the clinical effect was satisfactory.There was no statistically significant difference in VAS score and ODI evaluation between the two groups 1 week,1 month and 1 year after surgery(P>0.05),but there was A statistically significant difference in VAS score between the two groups 3 days after surgery,and the pain in group A was less than that in group B(P<0.05).There were 2 cases of cerebrospinal fluid leakage in each of the two groups.There were no incision infection,epidural hematoma and no internal fixation loosening in the two groups.Conclusion:No drainage tube placement after lumbar fusion can not increase infection of incision,complications such as spinal canal hematoma,as well as conventional drainage tube placement,and can achieve good treatment effect,but no drainage tube placement can reduce postoperative incision pain,facilitate patient turn care,early ambulation.This has advantageous to achieve rapid postoperative recovery.
