IntroductionDomestic animal bites are quite common, but mostly cause minor lesions, for which no medical help is sought. The objective of this study is to define the complications resulting from cat and dog bites that lead to hospital admission. This analysis led to updated guidelines for the treatment of dog and cat bites in humans.Patients And MethodsThe emergency department (ED) data of our hospital for the year 2004 were retrospectively analysed, seeking patients that presented with bite wounds from either cat or dog. The patient files were reviewed.Results34 patients, bitten by cats or dogs, presented to our ED in 2004. 73.5% of them (n = 25) consulted within 24 hours after the bite. In 11 of these patients (44.0%), primary closure of the wound was performed after thorough rinsing and evaluation of the dead space. All these patients were given prophylactic antibiotics. In none of these did the wounds need to be reopened afterwards. Nine patients (26.5%) did not present to the ED until after the day they were bitten. In all these patients, the bite wounds were located on the hand (n = 6) or forearm (n = 3). They all consulted because of complications. The main symptoms were limited and there was painful mobilisation of fingers and wrist, and swelling and redness in the area of the bite wound. Their wounds were thoroughly explored and in 6 of these nine late-presenting patients, a tendon lesion or a purulent flexor tenosynovitis was diagnosed. These six patients needed admission for further management. The mean admission duration was 6 days (range 4 to 10 days). None of the admitted patients showed any signs of limited mobility or disability during follow-up after discharge.ConclusionWhile cat and dog bites often cause minor lesions that can be treated by thorough wound care if presented early, the importance of possible late complications should not be overlooked. Patients that present with the symptoms of tissue infection due to a cat or dog bite should be examined adequately and may need admission. Due to aggressive treatment, we had no serious or disabling complications in our population after discharge.
