Background
Epistaxis in dogs can arise from nasal or systemic conditions and is challenging to manage due to limited accessibility of bleeding sites. This study aimed to design and test a nasopharyngeal tamponade device to provide compression and enable effective administration of hemostatic agents in the nasopharynx.
Methods
A proof-of-concept study was conducted using eight canine cadavers. A tamponade device was constructed using a condom affixed to a nasogastric tube, filled with a diluted contrast medium. Device placement was guided by CT or radiography, and its efficacy was assessed by creating a nasopharyngeal seal to prevent fluid leakage. Measurements of nasopharyngeal dimensions and device efficacy were analyzed.
Results
-The device was successfully placed and formed an effective nasopharyngeal seal in all cadavers, confirmed via radiography and digital palpation.
-Median nasopharyngeal length was 5.6 cm, and the required volume for sealing was 0.51 mL/kg (range: 0.38–1.24 mL/kg).
-Repositioning was needed in three cadavers, but subsequent adjustments resulted in effective placement.
-The device allowed prolonged contact of hemostatic agents within the nasal cavity without leakage, enhancing theoretical hemostasis.
Limitations
-The study was conducted on cadavers without active hemorrhage or preexisting nasal disease, limiting clinical extrapolation.
-The device's compatibility with brachycephalic breeds and live patients with active bleeding remains untested.
-Potential discomfort and breathing obstruction require use under anesthesia and intubation in live patients.
Conclusions
The nasopharyngeal tamponade device is a cost-effective and accessible tool for managing epistaxis in canines, with potential applications for enhancing hemostatic treatments. Prospective studies are required to validate its efficacy in clinical scenarios.
(A) Equipment required to place the tamponade device. (B) A condom is placed over the nasogastric tube. (C) Two circumferential
sutures are applied at the premeasured point. (D) The residual condom distal to the sutures is removed with a scalpel. (E) The guidewire is
removed, and an adaptor is attached to the tube. (F) Negative pressure is applied to remove any residual air within the tamponade device. (G)
Saline is instilled to fill the condom, ensuring that there is no leakage. (H) The condom is held vertically with the tip uppermost, and air within the
condom is removed.
