Objective:To explore the effects of discharge key task plan in patients undergoing lumbar intervertebral fusion surgery.Methods:Totally 125 patients who underwent lumbar intervertebral fusion surgery in Zhuhai Hospital of Traditional Chinese Medicine from June 2018 to June 2019 were selected by convenient sampling and divided into an observation group and a control group according to the random number table. Patients in the observation group received interventions with the discharge key task plan, while patients in the control group received routine care. The discharge readiness, compliance of treatment behavior, and Oswestry Disability Index were collected and compared between the two groups of patients.Results:Finally, 123 patients completed the study, with 62 in the observation group and 61 in the control group. The total scores and scores of all dimensions of readiness to discharge in the observation group were higher than those in the control group ( P<0.05) . The compliance with treatment behavior in the observation group 24 hours before discharge and 3, 6 months after discharge were higher than those in the control group ( P<0.05) ; and the repeated measures analysis of variance showed that the compliance scores of the two groups shoed statistically significant difference in the intervention time, between the groups, and in interaction effects ( P<0.01) . The Oswestry Disability Index in the observation group was lower than that in the control group 3 and 6 months after discharge from the hospital ( P<0.05) ; and the repeated measures analysis of variance showed that the Oswestry Disability Index of the two groups showed statistically significant difference in terms of intervention time, inter-group, and interaction effects ( P<0.01) . Conclusions:The discharge key task plan helps to improve the discharge readiness and compliance with treatment behavior, and reduce the lumbar intervertebral dysfunction in patients undergoing lumbar intervertebral fusion surgery.

Objective To summarize the diagnosis and treatment experience of surgical site infection(SSI)after percutaneous endoscopic lumbar discectomy(PELD).Methods A retrospective analysis was made on 11 cases of postoperative SSI after PELD from January 2016 to December 2022.After PELD surgery,severe lower back or lower limb pain occurred in all the patients,with a Visual Analog Scale(VAS)score of 7-9(average,8.1).The erythrocyte sedimentation rate(ESR)was 17-114 mm/h(average,54.4 mm/h),and the level of C-reactive protein(CRP)was 8-151 mg/L(average,56.5 mg/L).The MRI showed changes of inflammatory signals in the intervertebral space of the surgical area.The SSI was diagnosed at 2-17 d(average,9.5 d)after PELD surgery.All the cases were treated with antibiotics(4 cases with empiric antibiotic therapy and 7 cases with sensitive antibiotic treatment),8 of which underwent combined surgery,including percutaneous endoscopic lesion removal,catheter irrigation and drainage in 4 cases,posterior lesion removal in 2 cases,and posterior lesion removal combined with internal fixation in 2 cases.Results The patients were followed up for 14-75 months(average,36.8 months).According to the modified MacNab criteria,5 cases were excellent,4 cases were good,and 2 cases were fair.Conclusions SSI after PELD is characterized by acute onset,recurrent severe lower back or lower limb pain,elevated inflammatory markers,and characteristic imaging features.Standardized antibiotic treatment combined with surgery can achieve good therapeutic effects.
