Results indicated ATT and MGCS scores were useful for prediction of outcome for dogs evaluated because of trauma. Penetrating trauma, low blood lactate concentration, and performance of surgical procedures were predictive of survival to hospital discharge. The methods enabled collection of data for a large number of dogs in a short time.

Objective To report summative data from the American College of Veterinary Emergency and Critical Care Veterinary Committee on Trauma (VetCOT) registry. Design Multi-institutional veterinary trauma registry data report Setting VetCOT identified veterinary trauma centers (VTCs) Animals Dogs and cats with evidence of trauma presented to VTCs with data entered in the VetCOT trauma registry September 1, 2013 – March 31, 2017 Interventions VetCOT created a standardized data collection methodology for dog and cat trauma. Data was input to a web-based data capture system (REDCap) by data entry personnel trained in data software use and operational definitions of data variables. Data on demographics, trauma type (blunt versus penetrating), pre-admission care, hospitalization and intensive care requirement, trauma severity assessment at presentation (e.g., modified Glasgow coma scale [MGCS] and animal trauma triage [ATT] score), key laboratory parameters, necessity for surgical intervention and case outcome were collected. Summary descriptive data for each species are reported. Measurements and main results Twenty-nine VTCs in North America. Europe, and Australia contributed information from17,335 dog and 3,425 cat trauma cases during the 42-months reporting period. A large majority of cases presented directly to the VTC after injury (80.4% dogs, 78.1% cats). Blunt trauma was the most common source for injury in cats (56.7%); penetrating trauma was the most common source for injury in dogs (52.3%). 43.8% of dogs and 36.2% of cats were reported to have surgery performed. The proportion surviving to discharge were 92.0% (dogs) and 82.5% (cats). Conclusions The VetCOT registry proved to be a powerful resource for collection of a large dataset on trauma in dogs and cats seen at VTCs. While overall survival to discharge was quite high, further evaluation of data on subsets of injury types, patient assessment parameters, interventions and associated outcome are warranted.

Shock index is a simple and easy calculation that can be used as an additional triage tool and should prompt further investigation for hemorrhage if the values are >0.9.

Objective -To establish a reference interval for tissue oxygen saturation (StO 2 ) levels measured by a portable near-infrared spectroscope and determine site(s) for reproducibly measuring StO 2 levels in dogs. Design -Prospective experimental study. Setting -Veterinary teaching hospital. Animals -Seventy-eight healthy dogs. Measurements and Main Results -A portable device that quantitatively measures StO 2 levels directly in muscle tissue using near-infrared spectroscopy (NIRS) was topically applied to shaved sites over 4 muscle bodies. Readings from the sartorius muscle were obtained 100% of the time. The digital extensors and biceps femoris muscles provided similar readings, but less consistently obtained StO 2 values (70% and 67%, respectively). Mean StO 2 levels measured over these 3 sites were not statistically different from one another. When readings from these 3 sites were combined, a mean AE 1 SD of 92.9 AE 7.4% was obtained. The epaxial muscles produced a significantly lower mean AE 1 SD (68.5 AE 22.4%), and readings were obtained only 60% of the time. Conclusions -In dogs, a mean AE 1 SD of 92.9 AE 7.4% can be used to investigate clinical applications of NIRS. The sartorius muscle most consistently allows for detection of StO 2 levels (100%). The epaxial muscles are not consistent or reliable for obtaining StO 2 readings and are not recommended for clinical application of nearinfrared spectroscope. Sex does not significantly affect StO 2 readings at any site. Body condition score only affects readings obtained from the sartorius muscle.

Decompressive cystocentesis, in cats with urethral obstruction, followed by placement of an indwelling urinary catheter, did not result in a diagnosis of bladder rupture in any cat. The source of and clinical significance of the reported abdominal effusion is not known. Survival to discharge, duration of catheterization, and length of hospitalization were similar to previously reported populations.
