Abstract

Abstract:

Objective

To investigate the clinical effect of medical suspension bed for stage Ⅲ-Ⅳ gluteal-sacral pressure injuries after flap transplantation.

Methods

A retrospective analysis was conducted on the clinical data of 55 patients with stage Ⅲ-Ⅳ gluteal-sacral pressure injuries admitted to the Department of Traumatology， Burns and Plastic Surgery of Liuzhou Workers' Hospital from June 2021 to May 2025. All the patients received flap transplantation to repair the wound. Patients treated with conventional hospital bed after flap transplantation were assigned to the conventional bed group (29 cases), while those treated with medical suspension bed were assigned to the suspension bed group (26 cases). The wound healing time in the recipient area， the postoperative length of hospital stay， the total length of hospital stay， hospitalization costs， incidence of complications in the donor and recipient areas （such as hematoma， infection， incision dehiscence， flap necrosis， etc.）， and reoperation rate were observed.

Results

Compared with the conventional bed group， the suspension bed group showed significantly shorter wound healing time in the recipient area ［（12.8±3.4） days vs. （16.0±5.6） days， t=-2.47， P=0.008］， postoperative length of hospital stay ［（13.8±3.9） days vs. （16.8±6.0） days， t=-2.14， P=0.019］， and total length of hospital stay ［（27.9±4.6） days vs. （30.7±6.6） days， t=-1.78，P=0.040］. There was no statistically significant difference in hospitalization costs between the two groups ［（3.9±0.9） ten thousand yuan vs. （3.6±1.1） ten thousand yuan， t=1.17， P=0.124］.The total complication rate （7.7%） and reoperation rate （3.8%） in the suspension bed group were significantly lower than those in the conventional bed group （34.5% and 24.1%， respectively），with statistically significant differences （P values were 0.016 and 0.033， respectively）.

Conclusion

The application of medical suspension bed in the treatment of stage Ⅲ-Ⅳ gluteal-sacral pressure injuries after flaps transplantation can accelerate wound healing， shorten length of hospital stay， and reduce the risk of complications and reoperation.
