[Danhong injection, ligustrazine injection, combined adsorbable biomembranes prevented adhesion of tendons after the repair operation: a clinical research].

Objective To explore the effect and the mechanism of Danhong Injection(DI),Ligustrazine Injection(LI),and adsorbable biomembranes in preventing the adhesion of tendons and tissues.Methods Totally 120 patients all suffering from simple flexor digitorium tendon rupture on the hand zone two damaged by sharp weapons were randomly assigned to Group A(Dikang adsorbable biomembrane),Group B(Tianxinfu adsorbable biomembrane),Group C(Tianxinfu adsorbable biomembrane+Ligustrazine group),and Group D(Tianxinfu adsorbable biomembrane+DI group)in accordance with random digit table,30 cases in each group.Indicators such as total active movement(TAM)of the hand tendon,Minnesota manual dexterity test(MMDT),and finger flex strength test(FFST)were observed.Results The TAM and the favorable rate were higher in Group C and D than in Group A and B at post-operative 4 and 8 week(P0.05,P0.01).There was no statistical difference between Group C and D(P 0.05).Each index of MMDT was lower in Group C and D than in Group A and B(P0.05).There was no statistical difference in FFST among all the 4 groups(P0.05).Conclusions Combined application of LI or DI with Tianxinfu adsorbable biomembranes could effectively prevent the adhesion of tendons.DI showed equivalent effect as LI did.Besides,the combined application was superior in preventing adhesion to using Xintianfu adsorbable biomembrane or Dikan adsorbable biomembrane alone.
