To evaluate the feasibility of an improvised tamponade device allowing direct pressure to be applied to the canine nasopharynx.
Proof-of-concept study using 8 canine cadavers.
A tamponade device was made by placing a condom over a nasogastric tube and suturing it to match the length of the nasopharynx. The device was placed in the nasopharynx of canine cadavers via the nares and filled with diluted ioversol. Placement was then confirmed with radiography or computed tomography. Concentrated ioversol was infused into the rostral nasal cavity to assess for a nasopharyngeal seal, defined as no ioversol passing the device seen on imaging. Subjective assessment of adequate nasopharyngeal compression via digital palpation of the soft palate agreed with imaging findings. Repositioning was required in several cases, but with digital palpation, initial placement was more accurate. Subsequent effective placement and a nasopharyngeal seal were achieved in all 8 cadavers.
This device can be placed in the canine nasopharynx, and an adequate nasopharyngeal seal can be achieved, allowing direct compression of the nasopharynx and filling of the nasal cavity with solution. Confirmation of placement was successful with digital palpation and imaging. Further studies are required to investigate the use of this device in live patients.
评估一种可对犬鼻咽部施加直接压力的简易填塞装置的可行性。
使用8具犬类尸体进行概念验证研究。
通过将一个避孕套套在鼻胃管上并缝合以使其与鼻咽部长度匹配来制作填塞装置。该装置经鼻孔置入犬类尸体的鼻咽部，并注入稀释的碘海醇。然后通过X线摄影或计算机断层扫描确认放置情况。将浓缩碘海醇注入鼻前端鼻腔以评估鼻咽部密封情况，鼻咽部密封定义为在影像学上未见碘海醇通过该装置。通过对软腭进行数字触诊对鼻咽部压迫是否充分进行主观评估，结果与影像学检查结果相符。在几例病例中需要重新放置，但通过数字触诊，初始放置更为准确。所有8具尸体均成功实现了后续有效放置及鼻咽部密封。
该装置可置入犬的鼻咽部，并可实现充分的鼻咽部密封，从而能够对鼻咽部进行直接压迫并向鼻腔内注入溶液。通过数字触诊和影像学检查成功确认了放置情况。需要进一步研究以探讨该装置在活体患者中的应用。
