Q

What is your initial treatment of epistaxis?

A
  1. Patient must sit up and lean forward(to reduce BP and not swallow blood)- trotters manoeuvre 2. Squeeze nostrils tightly 3. Anaesthetise and then use a silver nitrate stick application 4. If that does not work use a nasal pack with ribbon gauze bismuth iodoform paraffin paste(bipp)

Q

How does allergic rhinitis occur?

A

The allergens bind to IgE and causes degranulation of the mast cells and that releases mediator substances such as histamine, leukotrienes and SRSA(slow reacting substance of anaphylaxis

What are the 3 major complications of facial trauma?

A
  • haemorrhage
  • respiratory obstruction
  • inhalational injuries
82
Q

What are the different types of respiratory obstruction?

A
  • intra-oral blood clots
  • blockage due to tooth fragments or dentures
  • facial fractures may narrow the orophyrangeal isthmus
  • The tongue may cause posterior blockage
83
Q

Wha is the Mx for respiratory obstruction?

A
  • intubation an tracheostomy
  • pulling the jaw forward to prevent posterior blockage of the tongue
84
Q

How does haemorrhage occur in the nose and how do you treat it?

A

When there is damage to the lamina papyracea and a tear in the anterior ethmoidal artery leading to epistaxis

85
Q

How do we treat bleeding in the nose?

A

-nasal packing and direct pressure to stop the flow of blood

86
Q

What is ARDS?

A
  • adult respiratory distress syndrome
  • where gatsric and blood contents are comatose which increase the morbidity and mortality
87
Q

What is treatment of ARDS?

A
  • adequate oxygenation and multi-organ failure
  • inhalation and tracheostomy
88
Q

What is cerebrospinal fluid rhinorrhea?

A

CSF- is a clear watery discharge coming out of the nose after facial trauma

-The usual site of trauma is the cribriform plate and posterior wall of the posterior sinus

89
Q

How do we distinguish between normal nasal secretions and CSF leaks?

A
