Recent ventilator-associated pneumonia (VAP) guidelines recommend considering abbreviated therapy in patients with non-Pseudomonas aeruginosa VAP if clinical signs resolve. However, using an arbitrary day cutoff or clinical signs can be suboptimal for some, especially multiply injured patients, resulting in relapse and/or antibiotic resistance. Previously, we showed that repeat bronchoalveolar lavage (BAL) could guide antimicrobial duration for community-acquired VAP in trauma patients. The purpose of this study was to determine the appropriate duration of antimicrobial therapy for VAP in trauma patients secondary to hospital-acquired pathogens. ⋯ Repeat BAL provides objective evidence for VAP resolution in the face of potentially confounding clinical factors. Hospital-acquired VAP can be managed effectively by a defined course of therapy with a low recurrence. Duration of antimicrobial therapy for VAP in trauma patients should be dictated by the causative pathogen.

Several thousand snakebites occur annually in the US, but fewer than 10 deaths occur. Most deaths are from envenomations by rattlesnakes (Crotalus species), but deaths from copperhead and water moccasin (Agkistrodon species) are rare. ⋯ Accurate identification of the pit viper species involved in snakebites is essential. Although envenomation by a rattlesnake (Crotalus species) may require antivenom and uncommonly surgery, a bite by a copperhead (Agkistrodon contortrix) rarely requires any intervention other than observation. The unnecessary use of antivenom should be discouraged.
