* Penetrating TM ruptures- f/u with ENT in 24 hours
* Otic abx if foreign material remains in canal
30
What are the 2 classifications of epistaxis?
* Anterior bleed: visualized on external exam MC @ Kiesselbach plexus
* Posterior bleed: unable to directly visualize, blood from bilat nares or in posterior pharynx, failure to control with anterior packing MC @sphenopalatine artery
* Use nasal speculum to attempt visualization of bleed
31
Management of epistaxis
* If severe bleed/hemodynamic instability: type and crossmatch blood (MC in posterior bleed and anticoag)
* Place in sniffing position: lean forward, neck in neutral position, nose straight
* Direct pressure after nose blow (to evacuate clots) via intranasal vasocontrictor --> oxymetazoline or phenylephrine followed by pinching nose for 10-15 minutes without disturbing pressure
32
What can you do if epistaxis is anterior and direct pressure has failed and bleeding vessel visualized?
Chemical cauterization with 1:1 oxymetazoline and lidocaine then silver nitrate on bleeding vessel
33
What are CI for chemical cauterization?
Active hemorrhage, bilateral bleeding, recent cauterization (within last 4-6 weeks)
34
What is used for epistaxis if chemical cautery fails?
* Thrombogenic foams and gels (gelfoam and surgical) applied directly to bleeding mucosa
* Floseal: thrombin injected directly into bleeding nare and nare filled completely, breaks down after 3-5 days
35
What are indications for nasal packing to treat epistaxis?
* Failure of chemical cautery
* Gel/foam not available
* Posterior epistaxis suspected
36
What are the 3 types of packing
Epistaxis ballon: easier to use and more comfortable, fabric with cellulose for platelet aggregation
Nasal tampons/sponge: coat with antibiotic, insert along nasal floor, irrigate if doesn't expand, and tape to face, remove in 2-3 days
Ribbon gauze: last packing resort, most uncomfortable for patient and most difficult to insert
37
What is a posterior packing alternative?
* 14-French foley catheter
38
What are complications of epistaxis?
* Vasovagal syncope
* Dislodgement of packing
* Recurrent bleeding
* Sinusitis
* Toxic shock syndrome
39
When would you admit and consult ENT for epistaxis?
* Posterior packing required or anterior epistaxis not controlled
40
If packing will be present >48 hours, what should you add to epistaxis treatment?
Amoxicillin/clavulanic acid (or cephalosporin or bactrim for PCN allergy)
41
What is follow up for epistaxis?
all packing removed in 2-3 days by ENT or ED 2 days ideal
42

68
What is the MC food that becomes lodged in esophagus
Meat
69

* Adults: retrosternal pain, dysphagia, vomiting, choking, coughing, aspiration if attempting to wash down FB
70
Physical exam of swallowed foreign bodies
Assess airay, nasopharynx, oropharynx, neck and chest
FB may be visualized in oropharynx
71
Diagnostic studies of swallowed foreign bodies
* Foreign body film: chest and abd with radiopaque objects, coins with circular face on AP/PA in the esophagus and if trachea will show circular face in lateral view
* CT chest without contrast: will show non-opaque objects and provide information on perforation and signs of infection
72
Interpretation of imaging for swallowed foreign object
* If passes pylorus can usually move through GI tract
* Increased risk of obstruction past pylorus if irregular or sharp or wide/long
73
Management of swallowed FB
* Assess for airway compromise and risk of aspiration
* Determine need for urgent endoscopy
* Expectant therapy: if object past pylorus and meets no red flags for obstruction
Distal esophagela objects: IV glucagon may relax lower sphincter and allow passage
Successful endoscopy without complications: discharge home
74
What should be done for food impaction
Complete esophageal obstruction --> emergency endoscopy
Partial obstruction: treat expectantly with f/u in 12-24 hours to ensure passage, if no passage endoscopy required
75
What should be done for coin ingestion
Coins in esophagus should be removed with endoscopy
76
What shoul dbe done for sharp objects
* If in esophagus, stomach, or duodenum, immediate endoscopy
* If distal to duodenum and asymptomatic daily xrays until passage
* If passage not within 3 days, general surgery
* COnsult surgery immediately if s/s of perforation: pain, emesis, fever, GI bleed
77
What should be doen for button battery ingestion
True emergency! Prompt removal if in esophaguse will cause rapid mucosal injiury and necrosis, perforation within 6 hours of ingestion
* If passed esophagus f/u in 24 hours for repeat exam
* Repeat x rays at 48 hours to ensure passage through pyloruys
78
What should be done for narcotic ingestion
* Commonly ingested inside condom
* Rupture can be fatal
* Endoscopy CI due to risk of rupture
* Often visible on plain film
* Admit for observation until packet reaches rectum
