Infection is one of the most important obstacles in the wound-healing process. Conventional methods used for the treatment of
wound infections have their own limitations and hence, are difficult to control. If
infection is not addressed well in time, it will further increase morbidity and cost of treatment. An attempt was made to develop a simple and effective treatment modality by using
citric acid as the sole
antimicrobial agent to control
bacterial infections of traumatic
wounds. A total of 259 cases of traumatic
wounds infected with a variety of bacteria were investigated for culture and susceptibility, and susceptibility to
citric acid.
Citric acid ointment (3%) was applied to traumatic
wounds to determine its efficacy in their treatment of traumatic
wounds. In a culture and susceptibility study, a total of 369 aerobic bacteria and 7 fungi were isolated, with Staphylococcus aureus (30.31%) being the most common isolate and
ciprofloxacin (61.43%) being the most effective agent. All the isolates were found to be inhibited by
citric acid in in vitro studies (minimum inhibitory concentration--500-2500 µg/ml).
Citric acid ointment was found effective in controlling
infections. Out of 259 cases, 244 (around 95%) were healed completely in 5-25 applications of 3%
citric acid. As
citric acid has antibacterial activity and wound-healing property; hence it is the best alternative for the treatment of traumatic
wounds. Besides these properties,
citric acid has no adverse effects and it is a good dressing agent.
