- Abstract
A patient with nasal hemorrhage would usually insert wadding composed of blood sucking material easily available at home, such as toilet paper, cotton, or gauze, into the nostril. The wadding tends to split under draw force, and is difficult for extraction from the nostril after blood sucking or generates adhesion with inner wall of the nasal cavity in hemostasis process, such that secondary injury occurs for nasal cavity during extraction. The most common problem occurs in that such wadding cannot press the bleeding site inside the nasal cavity of the patient in compliance with nasal cavity shape effectively, so that there is limited effect in mitigating intranasal bleeding symptom. Preclinical evaluation of new polyvinyl alcohol foam (PVAF) nasal matrix could be established by determining morphology, water permeability, macroporosity, and compression property.
