Comparison of 1% Silver Sulphadiazine and Chlorhexidine Dressing Combined Versus 5% Chlorhexidine Dressing Alone in Preventing Pin Tract Infection in External Fixators

ABSTRACT
Objective: To determine the efficacy of 1% Silver Sulphadiazine and Chlorhexidine dressing combined versus 5% Chlorhexidine dressing alone in preventing pin tract infection in external fixators.
Methods: This was a comparative study done in the Orthopedic Department Hayatabad Medical Complex(HMC) from March 2015 to March 2018 on 198 patients with external fixator in tibia. This study compares the frequency of pin tract infection(PTI) in patients treated with 1 % Silver Sulphadiazine and 5% Chlorhexidine combine (group A) and 5% Chlorhexidine alone(group B).Patients were labelled to have pin tract infection if signs of infection(redness, tenderness, discharge) were noted at pin sites.
Result: The total number of patients in our study were 198 and equally divided into group A and group B. Treatment in group A was effective in 90 (90.9%) patients while group B was effective in 71(71.7%). The difference was statistically significant (p value 0.001).
Conclusion: Combined 1% Silver Sulphadiazine and 5% Chlorhexidine was effective in preventing pin tract infection in majority of patients with external fixators than 5% Chlorhexidine dressing alone.
