Objective:
To investigate the clinical effect of subcutaneous undermining dissection with continuous negative pressure drainage for the closure of cystic cavity-type bedsore.
Methods:
12 patients with cystic cavity-type bedsore underwent surgical debridement and the wounds were closed after subcutaneous undermining dissection. The negative pressure drainage was put in the deep space. The healing process was observed.
Results:
Completed healing was achieved in all the 12 cases. The skin wounds healed after 17-20 days and the deep spaces closed after 36-43 days. 12 cases were followed up for 1 year with no occurrence.
Conclusions:
It is an easy and effective method to treat cystic cavity -type bedsore by subcutaneous undermining dissection with continuous negative pressure drainage.
