1
Q
Diff areas of epistaxis?
A
- Keisselbach’s plexus: anterior
- sphenopalatine plexus: posterior
2
Q
How should pt be sitting w/ epistaxis? Why?
A
- should be sitting straight up - 90 degrees:
- this decreases nasal arterial pressures
- prevents aspiration
- may have to modify if pt appears shocky
3
Q
Sig of posterior bleed as opposed to anterior bleed?
A
- distinguish b/t the 2: posterior won’t stop bleeding, anterior should be able to visualize
- if packing and cauterization isn’t working: most likely a posterior bleed
- posterior is more serious
4
Q
Hx questions to ask pt w/ epistaxis?
A
- one nare or both
- sensation of blood in back of throat
- hx of epistaxis, trauma, head/neck tumor, radiation or head/neck surgery
- family hx of bleeding disorders
- anticoag, NSAIDs, ASA?
5
Q
Underlying causes of epistaxis?
A
- nose picking
- dryness
- trauma
- anticoag or ASA therapy
- bleeding diathesis: heme (polycythemia, TTP, VW dz, hemophilia, aplastic anemia)
- FB
- allergies: nasal steroid use
- ASA? and HTN?
6
Q
Tx of epistaxis - step 1?
A
step 1: start w/ direct pressure:
- compress nares b/t thumb and index finger or 2 tongue depressors taped together - for 20 minutes, have pt lead forward or sit upright
- *this will have to effect on posterior bleeds
7
Q
Step 2 tx of epistaxis?
A
if still bleeding after direct pressure:
- apply a topical anesthetic+vasoconstrictor
- commercial prep like Afrin and cotton balls soaked in lidocaine 2%
- or make own by mixing 2% lidocaine and 1:1000 epi and soaking cotton balls in mixture
- place impregnated cotton balls in nare x 10 min
- remove cotton ball and evacuate clot (blowing or suction)
8
Q
Step 3 tx of epistaxis?
A
determine site of bleeding:
- you need good light, nasal speculum, suction, ENT chair and patience
- many times site is determined by age:
- kids - kiesselbach’s area - anterior
- adults - generally posterior to kiesselbachs area
- older adults - most difficult and often posterior
9
Q
Step 4 tx of epistaxis?
A
cautery w/ silver nitrate stick:
- if still bleeding and can visualize the bleeding area
- apply pressure w/ silver nitrate for 5-10 sec
- cauterize small area around bleeder as well
- apply abx oitment to area
- if this resolves the bleed then abx ointment for 7 days
10
Q
Step 5 tx for epistaxis?
A
anterior packing:
- indicated if all measures up to this pt have failed
- can use nasal tampons or nasal balloon catheters
- apply topical anesthetic to nare
- apply surgical lubricant to packing
- insert along horizontal plane to max depth
- foam polymers may need water to expand, some devices may reqr inflation
- after care:
remove packing in 48-72 hrs, oral abx reqd, pt to remain upright (even sleeping) for 48 hrs, no lifting and avoid laughing for 24 hrs
11
Q
if bleeding still exists after packing and cauterization what should you suspect?
A
- posterior bleed
- consult ENT emergently
12
Q
Tx of posterior epistaxis?
A
- direct pressure is ineffective, nasal packs are uncomfortable to place, posterior packed pts are often admitted for observation
- ENT consult is warranted
13
Q
Complications of posterior epistaxis?
A
- difficulty swallowing
- otitis media
- necrosis of nasal mucosa, TSS
14
Q
Nasal fx: how is dx made? Management?
A
- MC fx bone in face
- dx based on Physical :
nose usually edematous and tender, look for displacement, crepitus, epistaxis - inspection w/ nasal speculum mandatory to r/o septal hematoma
- mangagement: closed reduction - 2-10 days post injury to allow for reduction of swelling
15
Q
Complications secondary to nasal fx?
A
- septal hematoma - complications -cause necrosis, perf septum - untx can lead to saddle nose
- infection
- obstructed airway from septal deviation
- tx: drain hematoma
16
Q
When you see septal hematoma what should you suspect as etiology? tx? Tip off that it is a cartilage fx?
A
- adults: sig trauma and nasal fx
- kids: can occur w/ simple falls or minor altercations
- tx:
drain and pack, abx (augmentin) if abscess suspected - IV clinda and admission - cartilage fx: tip off - formation of bilateral hematoma - ENT referral
17
Q
Complications that occur from untx septal hematoma?
A
- saddle nose deformity
- septal abscess
- septal perf
18
Q
Presentation of external otitis?
A
- aka swimmers ear: pseudomonas
- edema, erythema of EAC w/ +/- exudate
- must see TM (if not make sure you clean out ear so TM is visible - make sure not perf)
- positive pinna tug
- tx is generally application of wick and cortisporin otic, local heat, analgesia
- have to r/o malignant otitis externa (goes intracranially - osteomyelitis) - need systemic tx: really painful, cellulitis
19
Q
CNS origin of vertigo?
A
