Antibiotic bone cement combined with vacuum sealing drainage effectively repairs sacrococcygeal pressure ulcer.

Objective: To investigate the effectiveness of antibiotic bone cement combined with the vacuum sealing drainage (VSD) technique for repairing sacrococcygeal pressure ulcer wounds.

Methods: A retrospective analysis was conducted on data from 136 patients treated at Yantai Affiliated Hospital of Binzhou Medical College between May 2020 and June 2022. The cases were devided into a control group and a study group according to their treatment regimen. Indicators of postoperative recovery including blood routine recovery time, hospital stay, antibiotic application time, and healing time were compared between the two groups. Before the procedure and 6, 12, 24, and 48 hours following the operation, the pain levels of patients in both groups were examined using a visual analogue scale (VAS). On the 3rd, 7th, 14th, 21st, and 28th days of treatment, the pressure ulcer scale for healing (PUSH) was used to measure the pressure ulcer area between the two groups. On the 7th, 14th, 21st, and 28th days following treatment, the capillary density values were compared between the two groups, along with the levels of interleukin-1β (IL-1β), interleukin-12 (IL-12), and c-reactive protein (CRP). The proportions of immunoglobulin M (IgM) and immunoglobulin G (IgG) levels, CD3+, CD4+, and CD8+ T cell subsets, as well as CD4+/CD8+ ratio, were compared between the two groups.

Results: The blood routine recovery time, hospital stays, antibiotic usage duration, and healing time were all significantly shorter in the study group compared to those in the control group (all P<0.05). At 6 h, 12 h, 24 h, and 48 h following surgery, the VAS score in study group was significantly lower than that of the control group (P<0.05). The study group also showed a greater reduction in pressure ulcer area, with lower PUSH scores observed on days 14, 21, and 28 (P<0.05). Post-treatment levels of IL-1β, IL-12, and CRP decreased in both groups, with significantly lower levels in the study group (P<0.05). Following therapy, both groups demonstrated significantly increased levels of CD3+, CD4+, CD4+/CD8+, IgM and IgG and reduced level of CD8+. These improvements were more pronounced in the study group (all P<0.05).

Conclusion: The combination of antibiotic bone cement and VSD is effective in enhancing recovery, reducing pain and inflammation, and improving immune response in the treatment of sacrococcygeal pressure ulcers.
