Abstract

Study Design:Retrospective, descriptive study.Objectives:Managing early surgical site infection following elective lumbar spine surgery remains a challenge with controversy regarding retention of instrumentation and bone graft. Wound closure may also pose considerable challenges. We aim to report on our method of managing deep surgical site infections complicating elective spine surgery with surgeon assembled deep vacuum dressings. Identification of causative organisms with their sensitivities was a secondary objective.Methods:Patients were identified from a prospectively maintained, single-surgeon database from 2003-2015. Patients who had an infective or trauma related diagnosis, cervical procedures, and were younger than 18 years were excluded. Records were reviewed to identify bacteriology, laboratory tests performed, antibiotics administered, and type and frequency of surgical management. One thousand two hundred twenty patients qualified for inclusion, with 19 identified as having developed acute wound sepsis.Results:All patients had surgical debridement on the day of presentation and the majority of wounds were managed with a vacuum dressing. In all but 1 patient was instrumentation retained. Specimens for culture were taken at each debridement and antibiotics changed accordingly. Patients received a minimum 6 weeks of antibiotics.Conclusions:The management of deep surgical site infection is labor intensive and frustrating for both surgeon and patient due to the unexpected prolonged admission. Management goals are identification and eradication of the causative organism with subsequent healing of the surgical wound. This process is enhanced with the use of negative-suction dressings made from theatre stock replaced at regular intervals and allows retention of bone graft and instrumentation in the majority of cases.
