Surgical/Trauma Flashcards
Liver lobectomy as treatment for spontaneous
hemoabdomen secondary to a ruptured liver mass in dogs; Histopathologic findings and survival outcomes
Reist et al_JAVMA_2022
Well-differentiated hepatocellular carcinoma cases: 36% (72/200) overall survival days: 356 days, benign masses 27.5% (55/200) 905 days, hemangiosarcoma 25.5% (51/200) 45 days, and other malignant tumors 11% (22/200), 109 days. Overall survival time for all dogs was 897 days.
Prognostic factors for survival included diagnosis, increased ALT, anemia, and whether a transfusion
was received. Overall survival time in dogs with increased ALT was 644 versus 63 days with normal values.
Epidemiology of severe trauma in cats
Lee_JVECC_2022
Cats were categorized by ATTS0–2 (mild,65.1%) and ≥3 (severe, 34.9%). There was no age difference between categories. Male animals, particularly intact animals, were overrepresented. Blunt trauma was more common than penetrating, with blunt trauma and a combination of blunt and penetrating trauma being more common in the severe trauma group. While 96.6% of cats with ATTS 0–2 survived to discharge, only 58.5% with ATTS≥3 survived. Only 46.8% of cats with severe trauma had a point-of-care ultrasound performed, of which 8.9% had free abdominal fluid noted. Hospitalization and surgical procedures were more common in the severe trauma group. Transfusions occurred more frequently in the severe trauma group but only in 4.1% of these cats. Other than ionized calcium, all recorded clinicopathological data (plasma lactate, base excess, PCV, total plasma protein, blood glucose) differed between groups.
The effects of sex and neuter status on trauma survival in dogs
Fontes_2022_JVECC
Of 2649 eligible dogs, 56% survived to hospital discharge (n=1469). Neutered females had a significantly higher survival rate (58.3% vs 51.3%; P=0.03) compared to intact females, and neutered males had a significantly higher survival rate (56.6% vs 50.7%; P=0.04) compared to intact
males. There was no significant difference in survival between intact females and intact males (P=0.87) or between neutered females and neutered males (P=0.46). Mean cumulative ATT score was higher in intact groups and was found to be a significant predictor of survival (P<0.01). Based on logistic models, overall odds of survival were 20.7% greater in neutered dogs.
