A prospective evaluation of risk factors for infections from dog-bite wounds.

摘要: OBJECTIVE: To define risk factors for infections from dog- bite wounds and to model the probability of wound infection in patients presenting without who are treated as outpatients. METHODS: A prospective survey 769 consecutive dog-bite victims over a two-year period community hospital emergency department (ED) with an medicine residency program. standardized wound-cleaning protocol was used, which included debridement closure when indicated. Wounds were examined at follow-up. Variables analyzed demographic data (patient age, gender, race); information (wound type, number, location, depth); treatment (prior hospital, ED debridement, suturing, tetanus or rabies shots, antibiotics). RESULTS: There 734 complete records. These had mean age 13.4 +/- 13.2 years (range, 4 months 71 years). Infection evident 2.5% upon presentation. 704 (765 wounds) managed outpatients distributed follows: 26.7% head/neck, 20.4% hand, 15.7% arm, 10.1% trunk, 9.5% thigh, 15.9% leg, 1.7% foot. 32.9% puncture, 39.9% full-thickness, 60.1% partial-thickness wounds. Wound diagnosed 2.1% Of these requiring surgical sevenfold higher rate (p = 0.01). Patients more than 50 sixfold younger 0.05). Stepwise logistic regression found following variables be best predictors infection: full-thickness [p 0.006, odds ratio (OR) 6.23], female gender 0.048, OR 2.88), 0.024, 5.01). Combinations three predict rates 0.35% 23.9%. CONCLUSION: low seen this cohort on outpatient basis. depth, patient clinical that predicted likelihood developing infection. Future interventional studies should concentrate high probabilities Keywords: Animal Bites; Dog Bites Language: en
