    Abstract:
    OBJECTIVE: To determine clinical features, outcome, risk factors for death, and efficacy of IV administration of lidocaine as a prophylactic treatment for ischemic reperfusion injury in gastric dilatation and volvulus (GDV) in dogs. DESIGN: Retrospective case series. ANIMALS: 112 dogs with GDV. PROCEDURES: Data pertaining to breed; time lag to admission; clinical, clinicopathologic, and surgical findings; lidocaine treatment; and postoperative complications were assessed for association with outcome. RESULTS: German Shepherd Dogs (28.6%) and Great Danes (17%) were significantly over-represented. Risk factors for death included time lag (> or = 5 hours vs < 5 hours) from onset of clinical signs to admission (46.0% vs 11.3%), rectal temperature (< or = 38 degrees C vs > 38 degrees C [< 100.4 degrees F vs > 100.4 degrees F]) at admission (40.0% vs 14.9%), presence or absence of ARF (67.0% vs 23.3%), presence or absence of suspected gastric wall necrosis (59.3% vs 16.0%), and untreated gastric wall necrosis, compared with treated gastric wall necrosis (100% vs 47.6%). Overall mortality rate was 26.8%; no significant differences were detected in mortality rate or postoperative complications between dogs that received lidocaine IV prior to surgical intervention (52.0%) and dogs that did not (48.0%). Mean +/- SD hospitalization time was longer in the lidocaine treatment group (3.5 +/- 1.9 days vs 2.5 +/- 1.4 days). CONCLUSIONS AND CLINICAL RELEVANCE: Presence of the identified risk factors should warrant aggressive treatment. Lidocaine treatment was not associated with mortality rate or postoperative complications, but was associated with prolonged hospitalization time.
