The low intra- and inter-operator variabilities in the caudal vena cava, aorta and caudal vena cava:aorta ratio measurements support their reliability and operator independency. The sonographic assessment of volaemia appears to be a promising non-invasive, repeatable point-of-care ultrasound protocol for assessment and monitoring of blood loss. Further studies are needed to assess the sonographic assessment of volaemia protocol in spontaneously bleeding dogs.

“…First, capnographs can be expensive and not ubiquitously present in veterinary emergency rooms or even in operating rooms. Secondly, when cardiac output is extremely low—or even zero during cardiac arrest—CO 2 may be undetectable even if the tube is correctly placed ( Gottlieb et al, 2020 ; Herreria-Bustillo et al, 2016 ).…”

“…Although described decades ago ( Raphael & Conard III, 1987 ), just recently ultrasound (US) has emerged as an alternative to confirm ET intubation in veterinary medicine ( Herreria-Bustillo et al, 2016 ). Studies in humans have shown promising results, demonstrating high accuracy for the method and a fast learning curve ( Chenkin et al, 2015 ; Chou et al, 2011 ; Liu et al, 2023 ).…”

“…Studies in humans have shown promising results, demonstrating high accuracy for the method and a fast learning curve ( Chenkin et al, 2015 ; Chou et al, 2011 ; Liu et al, 2023 ). Nonetheless, most research has focused on experienced practitioners and up to now only one study was performed in veterinary medicine ( Herreria-Bustillo et al, 2016 ). Thus, it is important to investigate if the method could also aid inexperienced personnel.…”

Although endotracheal intubation is usually a simple and fast procedure in dogs, some situations can be challenging and lead to the risk of tube misplacement in the esophagus—a life-threatening complication. Hence, confirming intubation is a cornerstone whenever this procedure is performed. Methods such as direct visualization or capnography present limitations insofar as they may be unreliable or unavailable under some circumstances. Ultrasound has emerged as a promising tool to confirm intubation in medicine. However, so far little research has been done on the subject in veterinary medicine. This study’s main goal was to investigate ultrasound performed by veterinary students as a confirmation method for intubation in canine cadavers after a brief training session (25 minutes). A total of 160 exams were performed with a microconvex probe by 20 students in 11 different cadavers on left and right recumbencies. Overall accuracy was 70.6% with a median success rate of 75% and a median time to diagnosis of 25 seconds. The number of correct diagnoses was statistically higher than the wrong ones (p<0.05) without difference between recumbencies. Sensitivity, specificity, and positive and negative predictive values were 72.5%, 68.8%, 69.9%, and 71.4%, respectively. The fastest diagnosis was performed in just 4 seconds, and among the top-performers, one student had 100% accuracy with a mean time to diagnosis of 16.8 seconds, and four students had approximately 88% accuracy. This study showed for the first time that even inexperienced veterinary students can have acceptable accuracy in confirming endotracheal intubation in dogs after a brief training session.
