OBJECTIVE: To evaluate the placement of V-Gel Advanced supraglottic airway device (SGAD) in cats.
STUDY DESIGN: Retrospective study.
ANIMALS: A total of 75 client-owned cats with V-Gel Advanced (SGAD) undergoing computed tomography (CT) scans.
METHODS: CT images of cats with SGADs in place and exhibiting normal capnogram waveforms were reviewed. The size, distance from the end of the SGAD connector to the incisors of the animal, closure of the anatomical area around the shoulders of the SGAD, perfect seal of the larynx, closure of the oesophagus, adequate size, presence of gas in the stomach, complications and other observations were recorded. Descriptive statistics and logistic regression were performed to assess the association of the factors studied with incorrect device placement.
RESULTS: A total of 69 CTs were included in the study. The SGAD did not seal the area around the shoulders of the SGAD, the larynx or the oesophagus in 62.3% (43/69), 14.5% (10/69) and 72.5% (50/69) of the CTs, respectively. The device was slightly or very rotated in 26% (18/69) and 5.7% (4/69) of the CTs, respectively. The device was touching the epiglottis in 2.9% (2/69) of the CTs. The SGADs were positioned too caudally and too rostrally in 1.4% (1/69) and 2.9% (2/69) of the CTs, respectively. No association was found between factors studied and incorrect device placement. No complications were recorded.
CONCLUSIONS AND CLINICAL RELEVANCE: Based on the results, normal capnography waveforms do not confirm the correct placement of the SGAD.
