Intraincisional medical grade honey decreases the prevalence of incisional infection in horses undergoing colic surgery: A prospective randomised controlled study

Abstract

BACKGROUND: Medical grade honey has previously been described as a prophylactic treatment for wounds. Local prophylactic treatment may be valuable in preventing post-operative incisional infections in horses undergoing colic surgery but has not been evaluated. OBJECTIVES: To establish whether medical grade honey gel, applied on the linea alba intraoperatively, decreases the prevalence of incisional infections in horses undergoing colic surgery with no associated adverse effects. STUDY DESIGN: Prospective blinded randomised controlled clinical study. METHODS: ) was placed in the incision followed by apposition of subcutaneous tissue and skin. Information regarding the incision and post-operative complications was obtained at five time points (24 hours, 48 hours, 5 days, 14 days and 3 months). RESULTS: Eighty-nine horses were included in the study. No adverse effects associated with treatment were observed. Horses in the treatment group had a lower rate of incisional infection compared with the control group (8.2% vs. 32.5%, P = .02). The protective effect of MGH had a calculated adjusted odds ratio (OR) of 0.2 (95% CI:0.07-0.8, P = .03). The number of patients required to receive treatment to prevent one case of incisional infection (NNEB) was 4.7. Risk factors associated with infection included: younger age (OR = 27, 95% CI: 2.3 to 306, P = .008) and diarrhoea 48 hours post-operatively (OR = 20, 95% CI: 1.5 to 277, P = .02). MAIN LIMITATIONS: Follow-up was performed by different veterinary surgeons, hence not completely uniform. CONCLUSION: Local prophylactic treatment with medical grade honey gel in the abdominal incision during surgery is safe and may significantly decrease the prevalence of incisional infections in horses undergoing colic surgery.
