Pulmonary Stents And HemoptysisScott Farquharson M.D.Dec 9th 2010 With thanks to Dr. Alain Tremblay and Dr. David JungenCase - 57 Y/O woman with HemoptysisRockyview Hospital00: 12 EMS patch 57 y/o female with gross hemoptysis, has endobronchial stent and difficult airwayAwake, alert, sats 98% on NRB, other vitals OK How would you prepare? Teus AM2Preparation for difficult airwayCode roomRT, NursingPrepare for awake intubationDAM cart, GlidescopeTopical LidocaineKetamineBig BerthaNotify other Ed physician re possible triple set up

Who is aware that there is an Interventional Pulmonologist on call?Objectives of TalkReview indications for calling Interventional PulmonologistDiscuss pulmonary stent use and complications that could be seen in the EDDiscuss airway management of life threatening hemoptysis in the ED

Case00:29 Pt arrivesT 35.9, P 150, BP 189/90, RR 40, Sats 96% NRBDrying blood in mouth, on face, hands and front of clothing. No active hemoptysis.StridorAble to speak 1-2 words at a timeIndrawing 15 minutes after call6History - EMSOral Ca 2002 with curative resection and subsequent reconstructionLung Ca 2006 in remission post chemo/radiation radiation scarring of lungsHas stent in L mainstem bronchus Had balloon bronchoplasty of R mainstem 5 days ago R1 as no active cancer Stent Card

Massive HemoptysisGreater than 600 cc of blood in 24 hrsNot very useful definition in ED setting (although Pts regularly stay more than 24hrs)Gross hemoptysisGross hemoptysis with respiratory distressGross hemoptysis with respiratory distress and hemodynamic instability Massive HemoptysisLiterature reports a Mortality of 25-65% with massive hemoptysis 1Majority die of respiratory failure from blood contaminating upper airways and alveoli 22 sources of bleeding in lungs possiblePulmonary circulationBronchial circulationMajority from bronchial circulation 3

Massive HemoptysisCauses tend to be unilateral 4TraumaCancerInterventioninfectionSystemic illness rarely a cause of massive hemoptysis 5

Management StrategyLocalize the bleedingAdvanced airway managementSimple intubation may not be enough to protect uncontaminated lung from bloodEarly mobilization of other specialties to control bleedingAnesthesiaIPMInterventional radiology - EmbolizationThoracic Surgery

Airway ManagementSelective ventilation of one lungNo special equipmentProtects 1 lungCan only ventilate one lungIf R lung intubated will occlude RULNo tamponadeHave to reposition tube to use FB

Selective Lung Ventilation

Airway ManagementDouble Lumen ET TubeCan ventilate each lung independentlyMost commonly placedCan be placed blindProvides protection of non bleeding lungNo direct tamponadeAllows only small FBSizes French35-37 women39-41 men

Double Lumen ET Tube

Airway Management- Bronchial Blockers Fogarty CatheterPassed beside ET tube Placed with FBAllows large FBCan place in lobar bronchiBalloon can migrate or leakFogarty Catheter

Airway Management- Bronchial Blockers Univent tubeCombined ET tube and bronchial blockerCan ventilate while placing blockerLarge diameter tube > 8.0Blocker placed with FB or blindAllows large FBCan place in lobar bronchiTube can migrate or leak

Univent Tube

Airway Management- Bronchial Blockers Arndt wire guided endobronchial blockerCan be added to regular ET tubeMultiport adapter allows for simultaneous ventilation, bronchoscopy and Blocker placementCan place in lobar bronchiTube can migrate or leak

46Airway ManagementAll methods are temporizingDefinitive hemostasisFBEmbolization by Interventional Radiology Thoracic SurgeryHigh failure rate in inexperienced hands

CaseNext 48 hrsPt showed evidence of anoxic brain injurySeized Had 2nd massive pulmonary bleedFamily decided no further interventionsDied ConclusionsIPM is available for appropriate consultsStent complications will often require FB interventionMassive Hemoptysis is difficult to manage involve appropriate specialties early
