Clinical Trial Summary
Each year, millions of burn, trauma, or surgical patients worldwide suffer from scarring that
severely affects their quality of life and social functioning. In order to prevent and treat
diseases related to abnormal scar hyperplasia, clinicians and researchers have adopted
various methods, such as scar grinding, surgical resection, drug injection in scar tissue,
cryotherapy, laser and so on. However, these methods can not effectively inhibit the abnormal
proliferation of scars and improve the adverse effects of existing scars on patients. To
date, there is no accepted gold standard for the effective treatment and improvement of
abnormal scar tissue.
Description:
Through a large number of literature review and preliminary experiments, we summarized and
found the following problems: a. The latest research on prevention of scar formation by
botulinum toxin type A is only aimed at surgical wounds from the wound type, and there is no
research on the scar prevention effect of trauma wounds. b. From the point of view of the
study site, there is no study on the effect of scar prevention only on the head, neck, chest
and other parts of the body. c. For the research results of botulinum toxin type A in the
prevention of scarring, the current research focuses on the effectiveness of botulinum toxin
type A at a certain concentration, and does not compare the effects of botulinum toxin type A
at various concentrations.
Therefore, in order to explore the "optimal concentration" of botulinum toxin type A to
prevent scar formation; To explore the effect of botulinum toxin A on scar prevention of
traumatic wounds and surgical incisions. To explore the effect of botulinum toxin A on scar
prevention in other parts of the body in addition to effective prevention of head, neck and
chest scar, We intend to focus on the effectiveness and "optimal concentration" of botulinum
toxin type A to prevent scarring, to determine the effect of this means on scar prevention,
to provide new ideas for botulinum toxin type A to prevent scarring, and to broaden the
methods of scar prevention.
Patients were randomly assigned to experimental group and control group. The experimental
group was treated according to botulinum toxin type A The concentration gradient of toxin was
set to 3 groups:1 U,2.5 U,5 U, and the control group was injected with 0.9% Nacl.Follow-up
was performed immediately after surgery,7 days,15 days,1,3, and 6 months. Follow-up was
performed according to SBSES, pruritus, pain, and patient satisfaction.
