Therapeutic Effect Of Surgical Site Continuous Lavage Drainage On Postoperative Infection After Thoracolumbar Posterior Internal Fixation

Objective To evaluate the efficacy of surgical site continuous lavage drainage in the treatment postoperative infection after thoracicolumbar spine posterior internal fixation.Methods Collected 19 the data off patients were collected in department of spinal surgery in our hospital from June 2014 to June 2019.Those patients underwent local continuous lavage and drainage of antibiotic lesions to treat early surgical site infections after posterior thoracolumbar spine surgery.Comparing case data of 12 cases of such patients treated,comparing the general conditions before and after treatment,the number of white blood cells,erythrocyte sedimentation,C-reactive protein,blood culture,the culture and resistance of pathogenic bacteria in lesion tissue and the time of cure Differences,VAS and ODI scores.Follow up the infection recurrence after cure and analyze the clinical efficacy.Results There was no significant difference in WBC values between the antibiotic group and the traditional group at each time point(P> 0.05).However,in terms of CRP,the antibiotic group the examination on the 5th day after surgery(31.32 ± 14.04 mg / L),the 7th day after surgery(22.05 ± 7.56 mg / L),and discharged(5.26 ± 2.44 mg / L)compared with the traditional group the examination on the 5th day after surgery(48.33 ± 27.25 mg / L),the examination on the 7th day after surgery(44.08 ± 24.38 mg / L),and discharge from the hospital(7.92 ± 2.68 mg / L),the differences were statistically significant(P <0.05).The ESR values of the two groups were compared.The antibiotic group the examination on the 5th day after operation(26.00 ± 8.05 mm / h)and the examination on the 7th day after operation(23.79 ± 7.38 mm / h)was compared with the traditional group on the 5th day after operation(48.67 ± 21.65 mm / h)and examination on the 7th day after operation(42.58 ± 15.72 mm / h),the difference was statistically significant(P <0.05).The postoperative lavage time in the antibiotic group(14.31 ± 3.46 d),the drainage tube placement time(15.95 ± 3.36 d),and the time to reach the standard of cure(19.32 ± 3.99 d)were shorter then the traditional group postoperative lavage time(19.08 ± 9.92 d),the drainage tube placement time(21.25 ± 10.44 d)and the time to reach the cure standard(25.75 ± 10.3 d).The difference was statistically significant(P <0.05).In the antibiotic group,1 case had a pulmonary infection;in the traditional group,1 had a pressure ulcer,1 had a deep vein thrombosis of the lower extremity,and 1 had a gastrointestinal discomfort.No recurrent infection occurred in the antibiotic group.One patient in the traditional group developed a surgical incision infection within 3 months.Conclusion 1.The methods of surgical site continuous antibiotic lavage drainage in lesions is effective in the treatment postoperative infection of thoraciolumbar spine after posterior internal fixation.2.The use of antibiotics in the lavage solution can control infection faster,and has the advantages of quick recovery,fewer recurrences and fewer complications.
