Pediatric dog bite outcomes: infections and scars

Area of Science:

• Trauma surgery
• Pediatric surgery
• Wound management

Background:

• Management of dog bite victims lacks consensus, with limited data on long-term patient outcomes.
• Key outcomes of interest include infection rates and unfavorable scar formation following dog bite injuries.

Purpose of the Study:

• To evaluate the impact of repair location and personnel on infection and unfavorable scar formation in dog bite victims.
• To identify factors contributing to adverse outcomes in dog bite wound management.

Main Methods:

• Retrospective review of 45 pediatric dog bite cases undergoing definitive repair from January 2013 to May 2016.
• Data collected included wound characteristics, repair location, personnel performing repair, post-repair infection, and scar assessment.
• Level of evidence for this retrospective study is level III.

Main Results:

• Unfavorable scarring was not significantly associated with repair location or the personnel performing the repair.
• Infection rates were not significantly related to the location of repair.
• A significantly higher infection rate (73%) was observed when repairs were performed by emergency physicians compared to surgeons (p=0.002).

Conclusions:

• Infection following dog bite repair is significantly associated with bedside repair by emergency physicians.
• Differences in wound preparation and repair techniques between emergency and surgical departments may contribute to varying infection rates.
• Standardizing repair techniques and developing a robust wound classification system could mitigate infectious complications and long-term morbidity.
