“…Therefore, comparing the diameter of the IVC with the diameter of the abdominal aorta corrects for patients of various age, size, and weight. Two recent studies validated ultrasonographic assessment of CVC/Ao using the spleno‐renal and hepatic views to estimate volemia in dogs . In our study, a RV for CVC/Ao was not calculated because of poor inter‐rater variability, but means (±SD) were provided.…”

“…In veterinary medicine, 2 studies reported a positive correlation between CVP and caudal vena cava diameter (CVC D ) in anesthetized dogs receiving IV fluids and positive pressure ventilation . Three recent studies evaluating CVC diameter, CVC collapsibility (CVC CI ), and the CVC to Ao ratio (CVC/Ao) showed promise in evaluation of intravascular volume status in dogs . Another study on healthy dogs undergoing general anesthesia and mechanical ventilation reported that the CVC CI is a reliable predictor of fluid responsiveness.…”

BackgroundClinical assessment of intravascular volume status is challenging. In humans, ultrasonographic assessment of the inferior vena cava diameter, directly or as a ratio to the aortic diameter is used to estimate intravascular volume status.ObjectivesTo ultrasonographically obtain reference values (RV) for caudal vena cava diameter (CVCD), area (CVCa) and aortic ratios using 3 views in awake healthy dogs.AnimalsOne hundred and twenty‐six healthy adult dogs from clients, students, faculty, or staff.MethodsProspective, multicenter, observational study. Two observer pairs evaluated CVCD by a longitudinal subxiphoid view (SV), a transverse 11th‐13th right hepatic intercostal view (HV), and a longitudinal right paralumbar view (PV). Inter‐rater agreements were estimated using concordance correlation coefficients (CCC). For body weight (BW)‐dependent variables, RVs were calculated using allometric scaling for variables with a CCC ≥ 0.7.ResultsThe CCC was ≤0.43 for the CVC/aorta ratio at the PV and ≤0.43 in both inspiration and expiration for CVC at the SV. The RVs using allometric scaling for CVCa at the HV for inspiration, expiration, and for CVCD at the PV were 6.16 × BW0.762, 7.24 × BW0.787, 2.79 × BW0.390, respectively.Conclusions and Clinical ImportanceThe CVCD, measured at the HV and PV in healthy awake dogs of various breeds has good inter‐rater agreement suggesting these sites are reliable in measuring CVCD. Established RVs for CVCD for these sites need further comparison to results obtained in hypovolemic and hypervolemic dogs to determine their usefulness to evaluate volume status in dogs.

Objective: To describe the technique and findings of the 'veterinary focused assessment with sonography for trauma-airway, breathing, circulation, disability and exposure' protocol in dogs suffering from trauma. Materials and MethOds: Prospective observational study on a new point-of-care ultrasound protocol on 64 dogs suffering from trauma and comparison of findings with radiology. results: Comparison of the results of this new ultrasound protocol for trauma patients with radiography findings for pneumothorax, pleural effusion, alveolar-interstitial syndrome and abdominal effusion revealed positive agreement of 89, 83, 100 and 87% and negative agreement of 76, 83, 76 and 92%, respectively. Novel findings of the 'veterinary focused assessment with sonography for trauma-airway, breathing, circulation, disability and exposure' exam, which were not previously reported for dogs undergoing focused assessment with sonography for trauma, included alveolar-interstitial syndrome (suggestive of pulmonary contusions), diaphragmatic hernia, retroperitoneal effusion and tracheal injury. Our new technique may also help identify increased intracranial pressure via changes in optic nerve sheath diameter and haemodynamic instability through the evaluation of the caudal vena cava and cardiac function.clinical significance: The described ultrasound examination protocol can be rapidly performed during resuscitation on dogs suffering from trauma and it may detect injuries previously undetectable using other veterinary point-of-care ultrasound protocols.
