Nonvenomous snakebite in Massachusetts: prophylactic antibiotics are unnecessary.

STUDY

OBJECTIVE

To investigate wound infection in nonvenomous snakebite.

DESIGN

Prospective clinical series.

SETTING

Massachusetts Poison Control System.

PARTICIPANTS

Seventy-two consecutive children and adults with nonenvenomated snakebite wounds.

INTERVENTIONS: Patients were examined and advised that there was no published clinical evidence that prophylactic antibiotics were beneficial for nonenvenomated snakebites. They were re-examined five to ten days after the bite.

MAIN

RESULTS

Four patients used prophylactic antibiotics; 68 did not. There were no wound infections. Plain radiographs revealed a snake tooth fragment in the persistently tender wound of one patient bitten by his pet python.

CONCLUSION

Despite reports that pathogenic bacteria can be isolated from snakes' mouths, nonenvenomated snakebites in Massachusetts usually do not require prophylactic antibiotic therapy. Radiography is occasionally indicated for persistently tender wounds inflicted by large snakes.
