BACKGROUND: Silver sulfadiazine (SSD) has been the standard topical antimicrobial for burn wounds for decades. Recently, nanometer-sized silver particles are available which have high surface to volume ratio and remain effective even at a very low concentration and minimizes the chance for tissue toxicity due to silver. Hence, we conducted a randomized controlled trial to compare the effectiveness of topical SSD and nano-crystalline silver (AgNP) hydrogel in burn wounds management.
MATERIALS AND METHODS: Study was conducted in the Burn Unit of IPGME&R & SSKM Hospital Calcutta, from January 2011 to August 2012. Patients with 2° burn injury were randomly allocated to SSD and AgNP treatment group. Clinical assessments of burn wound were done on every week till 4(th) week and on completion of treatment.
RESULTS: Data for evaluation were obtained for 54 patients on SSD (2° deep-dermal cases 27) and 52 (2° deep-dermal cases 31) on AgNP treatment. Healing status of 2° deep-dermal burns was more satisfactory for AgNP group than SSD treatment at 4 weeks. Among patients receiving AgNP, 80.6% showed at least 50% healing of 2° deep-dermal wounds compared to 48.1% on SSD at 4 weeks (P = 0.001). The figures for complete healing at 4 weeks were, respectively, 4% and 0% (P = 0.116).
CONCLUSIONS: AgNP can be an effective and superior alternative to SSD for burn wounds, particularly 2° deep-dermal burns. Healing can be expected, in general, in 6 to 8 weeks time, depending upon the extent of body surface involvement.
