In medicine, a nasopharyngeal airway (NPA), nasal trumpet (because of its flared end), or nose hose, is a type of airway adjunct, a tube that is designed to be inserted through the nasal passage down into the posterior pharynx to secure an open airway. It was introduced by Hans Karl Wendl in 1958. [1]
Typically, dissolvable nasal packing is first attempted; if the bleeding persists, non-dissolvable nasal packing is the next option. Traditionally, nasal packing was accomplished by packing gauze into the nose, thereby placing pressure on the vessels in the nose and stopping the bleeding.
Nasal obstruction characterized by insufficient airflow through the nose can be a subjective sensation or the result of objective pathology. [10] It is difficult to quantify by subjective complaints or clinical examinations alone, hence both clinicians and researchers depend both on concurrent subjective assessment and on objective measurement of the nasal airway.
Surgicel is a hemostatic agent (blood-clot-inducing material) made of an oxidized cellulose polymer (polyanhydroglucuronic acid), manufactured by the Ethicon subsidiary of Johnson & Johnson.
Nasal strips, designed for humans, in varying colors and sizes. A nasal strip, external nasal dilator strip or nasal dilator strip is a type of adhesive bandage with embedded plastic ribs or splints that is applied across the bridge of the nose and sides of the nostrils, to assist in keeping the airway open.
Gamgee Tissue has a thick layer of absorbent cotton wool between two layers of absorbent gauze. [2] It represents the first use of cotton wool in a medical context, and was a major advancement in the prevention of infection of surgical wounds. It is still the basis for many modern surgical dressings.
Oxygen can be insufflated into the nose by nasal cannulae to assist in respiration. Mechanical insufflation-exsufflation simulates a cough and assists airway mucus clearance . It is used with patients with neuromuscular disease and muscle weakness due to central nervous system injury.
Monocryl is a synthetic, absorbable suture manufactured in Cornelia, Georgia, USA, and trademarked by Ethicon.It is composed of poliglecaprone 25, which is a copolymer of glycolide and epsilon-caprolactone. [1]
