Pain in the Neck!An EBM review of emergency department ENT Petr Balcar FRCPC Dec 15, 2011
Outline • Review best evidence in management of • Epistaxis • Fishbone FB • Tonsillitis • Post Tonsillectomy
Epistaxis Questions • Discuss evidence for: • INR • Cool compress • Topical antibiotics • Hemostatic agents • Oral antibiotics in packing • Safety of bilateral packing
Epistaxis: Pearls • Speculum parallel to floor! • Cauterize • Only controlled bleed • Periphery inward • 1cm around bleeder • Wipe excess AgNO3 off • Rapid Rhino • No saline/vaseline • Impairs mesh thrombosis • Recheck cuff 10-15min
Epistaxis: Anticoagulation • Not routine • Warfarin with therapeutic INR • 25% annual rate • Rare to need reversal • Discussion point: • Do all need ENT FU?
Epistaxis: Cool Compress • BestBets review • 3 small studies: • 1. Sucking ice = nasal vasoconstriction • 2. Neck ice packs = nasal vasoconstriction • 3. Forehead ice = 22/28 bleeds stopped • Summary: • Scant evidence • Benign intervention • Discussion point: • Should we hand out ice at triage? • Anyone want to do study?
Epistaxis: Topical Antibiotics • Multiple pediatric studies • Intranasal antibiotic x 4wks = cautery • No long term benefit • Minimal sefx • Staph carriage in adults • Walker and Baring 2009 • Small RTC n=49 • Nasal swabs • No difference in S. aureus carriage ~21% • Conclusion • Consider in pediatrics
Epistaxis: Hemostasis Agents • Multiple thrombogenic products • Quixil (fibrin glue spray) • Floseal (thromin gel) • Surgicel • Gelfoam • Avitene • Positive effect in small studies, few RCTs • Primarily developed for surgical use
Epistaxis: Fibrin Glue • Vaiman 2002 • RCT n 204 • Fibrin glue (Quixil) vs AgNO3 vs Cautery vs foam packing • ~93% immediate cessation • Mean 2.5 min • Fewer mucosal sefx
Epistaxis and Tranexamic Acid • Lysine derivative • Antifibrinolytic • Prevents plasmin to plasminogen • Hereditary hemorrhagic telangectasia • Case studies • Benefit of intranasal spray • Cochrane study under way
Epistaxis: Antibiotics with Packing • Postoperative rates 16 : 100,000 • PO antibiotics do not reduce nasal staph • No good studies: very rare event • Multiple side-effects of antibiotics • Most ENTs do it • Higher risk elderly, immunocompromised, prolonged pack • Discussion Point: • Do you start antibiotics?
Epistaxis: Bilateral Packing • Hollis 2011 • Anatomical model • Bilateral pack = decrease in septal deflection • Hady 1983 • Healthy volunteers packing • ABG at 24 hrs • Increased CO2, decreased PO2, pH equal • Loftus 1994 • 19 pts, posterior pack • Pulse oximetry monitor x 1200hrs • No desats
Epistaxis: Bilateral Packing • Historical cases with bad outcomes • Posterior packing patients died • Hypothesized nasopulmonary reflex • No current evidence of significant morbidity/mortality with bilateral packing • Posterior bleed patients need admit • Anterior bleed with bilateral pack • Consider DC in healthy patients, admit in frail/elderly • Discussion point: • Who does bilateral packing? • Do you admit them?
Fish Bone: Questions • How useful is plain X-ray? • How useful are symptoms? • Do all need scope?
Fish Bone: Are Bones Opaque? • Lue 2000 • 10 fish bones in cadaver head/neck • Blinded radiologists • Plain Xray 39% sensitive • CT 9/10 found • Cooking did not change opacity • Variability by species, orientation • Hone1995 • 10 fish bones in cadaver neck • 9/10 seen by both rads
Fish Bone: Clinical Xray Utility • Several clinical imaging studies • Sensitivity ~30% • Specificity ~88% • Ngan 1990 • Prospective n=358 • Clinical symptoms not reliable for FB • Clinical symptoms did localize FB if present • 117 bones found • 21 direct removal • 82 endoscopic removal
Fish Bone: Clinical Relevance • Impacted oropharyngeal bone location • Tonsils, base of tongue, vallecula • Impacted bones migrate! • Many case reports of significant pathology • Abscess, vascular • Should not be ignored! • Discussion point: • Do you xray all patients? • Do you get ENT/GI FU for all patients?
Pharyngitis: Questions • Review pathogens • Best evidence: • When to treat • Which antibiotics and how long • What to do if treatment fails • Analgesia
Pharyngitis: Bug Pearls • Usually viral • Consider EBV • GAS • Very common • Serious Complications • GBS/GCS minimal complications • HIV in at risk population • Early diagnosis/treatment • Mycoplasma / Chlamydia • Peds RCT n=133 • >30% carriage, not improved by Azithro • Ghonococcal • 5-15% carriage in MSM • Rare symtomatic, Rc Ceftriaxone • Diptheria • Un-immunized, endemic travel
Pharyngitis: Why Treat GAS? • Prevent complications • Suppurative • Rheumatic Fever • Up to 9 days post ssx • Scarlet Fever • Reduce symptoms • If within 48hrs • Reduce transmission • ~35% close contacts • Within 24hr, 80% swab neg
Pharyngitis: Antibiotics • Penicillin • 100% susceptibility • Pen V PO x 10days • Pen G IM lasts 3-4 weeks! • Amoxicillin • 100% susceptibility • Tastes better (yum) • AOM 15% • Clindamycin • 93% susceptibility • Better staph/anaerobe
Pharyngitis: Antibiotics • Cephalosporins • 100% susceptibility • Casey et al 2004 • Meta analysis: pen vs cephalosporin • <18yrs, n=7135 • Clinical and culture cure • Both superior in cephalosporins • Cost more, increased use in community • Macrolides • 93% susceptibility • Meta analysis shows improved compliance
Pharyngitis: Why Antibiotics Fail • Confirmed GAS • Chronic Carrier (up to 20% peds) • Poor compliance • Re-infection • Pet, toothbrush, dentures • Other beta-lactamase flora • Poor antibiotic penetration of tissue • Resistant strain (No pen resist strain Identified!) • Treat too early, reduced immune response • Non GAS • Suppurative complication
Pharyngitis: When Treatment Fails • No Specific Evidence • Screen for atypical etiology • Look for abscess • Repeat culture GAS + • Consider other PO Abx +/- IM Pen • Recurrent episodes • Consider testing family and treat all +ve • Consider chronic carrier with Viral • 6/year = tonsillectomy
Pharyngitis: Evidence for Steroids • All ENT’s do it! • Cochrane study in progress • Multiple small studies • Pediatrics • 3 studies • Oral Dexamethason • Adults • 7 studies • IM or PO steroid • Overall ~ 5-6hr quicker pain relief • No Early difference in Sefx
Pharyngitis: Summary • Consider atypical causes • High risk: tearly + swab • Antibiotics • Penicillin still 1st choice • Cephalosporins excellent • Amoxil peds • Failure re-test • Analgesia • Topical lozenges • Steroids
Peritonsillar Abscess: Questions • Utility of US • Best treatment options
Peritonsillar Abscess: US Imaging • Relatively new • Several small studies • Excellent for Abscess locations • Intraoral = 95% sensitive • Transcutaneous = 80% sensitive
Peritonsillar Abscess: US Drainage • Costantino 2010 • RCT n=23 • ED physician, US vs blind drainage • Diagnosis 100% vs 63% • Aspiration 100% vs 42% • ENT Referal 8% vs 55%
Peritonsillar Abscess: Treatment • Several poor studies • Overall I&D = Needle • ~90% success rate • Consider primary tonsillectomy • Antibiotics • Usually polymicrobial • IV Pen/Clinda • PO Pen/Clinda/Amox-clav • Steroids reduce morbidity
Peritonsillar Abscess: Summary • Needle okay • US guided probably best • Iv steroid dose helps • Discussion point: • Lets buy an oral probe!
Post Tonsillectomy: Questions • Indications • How much bleeding is concerning? • Analgesic options
Post Tonsillectomy: Bleeding • Significant hemorrhage 1-3% • 1:40,000 fatal • 95% secondary (>24 hr) • Up to 39 days • Blood = ENT • Consider admit • Active bleed • Pressure • Epi • +/-Thrombin
Post Tonsillectomy: Analgesia • Expected pain pattern: • Improve over 3-5 days • Then increases for 1-2 days • Resolves • Steroids given periop • NSAIDS?
Post Tonsillectomy: NSAIDS • Surgeon will not be pleased! • Several RCTs, 2 good reviews • Marret 2003 • N = 262 • Need for OR • NNH 29 • Moinche 2003 • N = 970 • Need for OR • NNH 60 • Reduction in N/V vs opioid • NNT 9
Post Tonsillectomy: Summary • Delayed pain presentation • Any bleed need ENT FU • No NSAIDs
