Ultrasound of the caudal vena cava pre, trans and post surgery as a determination of hypotension in dogs
Abstract
Blood volume is a fundamental factor in hemodynamic functionality that determines the correct homeostasis in living beings. Both hypovolemia and hypervolemia are detrimental factors in the patient who suffers from them. The measurement of the collapsibility index of the caudal vena cava (ICVCC) is a predictive marker of certain disorders, which can be corrected by administering intravenous fluids and thus being able to assess its adequate response by ultrasound. Through the use of ultrasonography, measuring the maximum and minimum diameter of the CCV using the M mode of the ultrasound equipment, which allows measuring the internal diameter of the CCV, before, during and after the surgical procedure. In patients with evidence of caudal vena cava collapse, Lactated Ringer’s solution was administered regardless of the surgical moment to later measure CCV again and verify that they responded to fluid therapy.
