Controlled randomized prospective study comparing two forms of treating the bone graft donor site in vertebral-spine surgery

OBJECTIVE: Compare the placement of absorbable jelly Gelfoan® versus the placement of a only a suction drain on the donor site, assessing post-operative pain, the presence of complications and the patient follow up. METHODS: Through a computer program, 30 patients were randomized, of which 14 patients using Gelfoan® with an anesthetic and 16 patients using a suction drain. All patients were assessed in five consecutive periods, the pain was assessed based on the visual analogue scale (VAS), and the incidence of complications was observed. Patients with an anterior or posterior approach were included and only the iliac bone was considered the donor site. Patients between 18 and 70 years of age from both genders were included. RESULTS: It was observed that the post-operative pain was less intense with the gelatin in the first assessments, but the mean results were similar and did not present statistical differences between both. In the average of the assessments, the visual analogue scale for pain was of two, not observing complications in the graft donor site. CONCLUSION: We have concluded that the approach with Gelfoan® with bupivacaine improves pain in the first 48 hours post-operatively when compared to the vacuum suction drain, but in average both techniques are safe, with the presence of residual pain in both interventions and a low complication rate, with none observed in our study.
