Dog bites

Dog bites in children treated in a pediatric emergency department

ISSUES AND PURPOSE

Unintentional injury is the leading cause of death and disability among children. This study sought to describe the characteristics of dog bite injuries to aid in promoting healthy environments for children.

DESIGN AND METHODS

This descriptive, retrospective study of one hospital's 1997 emergency department records detailed dog bite injuries to children and adolescents and resultant emergency treatment (N = 204).

RESULTS

Children < or = 5 years of age accounted for 49% of the injuries. The biting dog's owner was generally a parent or neighbor. Only 2 children received rabies prophylaxis.

PRACTICE IMPLICATIONS

Parents and children need information about safe interactions with dogs, including community leash laws and quarantine guidelines. Nurses should know the procedures for reporting dog bite injuries to local health authorities. Interested nurses can find many opportunities to assist with community safety campaigns.

Immunogenicity and safety of low-dose intradermal rabies vaccination given during an Expanded Programme on immunization session in Viet Nam: results of a comparative randomized trial

The World Health Organization recently recommended a rabies vaccine pre-exposure schedule using 3 intradermal (i.d.) injections of one-fifth the standard intramuscular (i.m.) dose of current cell culture vaccines as a cost-reducing alternative for developing countries. As a strategy to improve further the acceptability of childhood rabies immunization, we assessed, in a controlled, randomized trial performed in 240 Vietnamese infants, the possibility of associating i.d. administration of a one-fifth dose of purified Vero-cell rabies vaccine (PVRV) with routine Expanded Programme on Immunization vaccines given at 2, 3 and 4 months of age (diphtheria, tetanus, whole-cell pertussis and inactivated poliomyelitis combined vaccine, DTP-IPV). Safety and immunogenicity results were compared with a group of infants given 2 i.m. doses of PVRV (2, 4 months) in association with DTP-IPV (2, 3, 4 months). After i.d. injection, more infants experienced local reactions, particularly redness, but these reactions were generally mild and transient. The rate of systemic reactions was the same in both groups. Although the rabies antibody titres (rapid fluorescent focus inhibition test) were higher 1 month after the third vaccine dose in the i.m. group (30.6 IU/mL vs 12.0 IU/mL in the i.d. group), all infants in both groups had achieved WHO-acceptable protective antibody titres (> or = 0.5 IU/mL) at this time. There was no evidence for any interference between DTP-IPV and rabies vaccine, supporting the interest of a low-dose i.d. PVRV pre-exposure regimen in infants living in rabies-endemic developing countries.

Dog bites in children admitted to Pennsylvania trauma centers

Dog bites are a major public health problem in the pediatric population, requiring emergency treatment for wound repair and possible hospitalization in a trauma center. Data from the Pennsylvania Trauma Outcome Study were analyzed, and the records of 183 pediatric dog bite patients from 1990 to 1995 were evaluated. Dog bites were found to constitute a very small proportion of the total pediatric admissions to Pennsylvania trauma centers; however, the findings were similar to other reported studies.

Minor pediatric injuries

Injuries are a common source of childhood morbidity and mortality. The initial evaluation should follow in a sequential fashion to determine the extent of injuries. Most minor injuries can be treated safely and cost-effectively in an office setting. The principles of wound care include adequate hemostasis, tissue debridement, removal of imbedded foreign bodies, and appropriate closure or coverage of the wound to optimize healing. Appropriate use of antibodies, tetanus prophylaxis, and rabies immunization will minimize complications. With proper selection and treatment, the outcome of children with minor injuries should be excellent.
