5 | CONCLUSION
Each patient with DNSI develops individualized treatment plan according
to his own situation. Conservative treatment and surgical treatment are
feasible treatment plans, which can complement each other. In view of
the pyogenic cavity aerobic therapy proposed by us, it has been proved
that it is a good treatment method for patients with DNSI and incision
and drainage of pus, and the operation process is simple. Combined with
negative pressure drainage, it shortens the treatment time of dressing
change, reduces the physical and psychological pain of patients. The
method not only reduces the workload of clinical doctors, but also
reduces the risk of rupturing large blood vessel rupture and damaging
important nerve structure during dressing change. The materials used in
the treatment process are common clinical materials. Therefore, we
believe that this method is worthy of clinical promotion. Our team has
summed up the experience, but many of the mechanisms are not yet fully
clear, and need to be further studied and verified.
