9 July 2012 to November DOCUMENTED INTUBATIONS

10 INDICATIONS RESP FAIL DEC LOC SHOCK OTHER NO DATA

11 Urgency

12 BVM Class

13 Techniques

14 Complications Severe: SBP <70mmHg if >90 mmhg O2 Sat n <80% if >90% Esophageal intubation Other: aspiration, dental trauma, endobronchial intubation, pneumothorax Cardiac Arrest or Death

15 Key findings 1 Attempt (n =224 ) >1 Attempt (n=108) Other Complications % Severe Complications % vs 41% 8.0% vs 30% 1. Others Complications: Aspiration, dental trauma, endobronchial intubation, pneumothorax or any severe complication 2. Severe Complication: - Hypotension: Systolic blood pressure <70mmHg if >90mmHg prior to attempt - Hypoxia: oxygen saturation <80% if >90% prior to attempt -Esophageal intubation -Cardiac Arrest -Death within 30 Min of Intubation

16 Greater than one attempt at ETI was associated with a 4-fold increase in severe, and a 5-fold increase in total complications. Although previous publications found greater than 2 attempts associated with increased complications, recent publications found this association with greater than one attempt, consistent with our findings.

17 Should RTs be intubating? A. Yes, of course B. No, are you nuts?

18 Is It just Us? Do we Just Suck at Intubation at RCH? Fiberoptic intubation gone horribly wrong

19 Do we suck at RCH? A. Yup, you suck B. Nope, that sounds normal C. Nope, you guys are some kind of A/W wizards

20 Complications Rates Authors Jaber 2006 (ICU)N=253 Griesdale (unpublished) (ICU) Jaber 2010 (ICU) N=121 Sackles 2013 N=1828 RCH Data, N=332 Total complications Severe Complications 50% 28% 38% 24% 34% 21% 25% 19% 15%

21 How do we measure up to others

22 Complications Increase with >1 Attempt Authors Griesdale 2008 n=136 Sackles 2013 n=1828 RCH Data n=332 Absolute Risk of Adverse Event 18% 38% 14% 53% 8% 41%

23 Prospective cohort study of pts intubated by ICU team N=136 Excluded Cardiac arrest pts >1 attempt associated with risk of severe complications OR 3.31 (95% CI:1.30,8.40, p=0.01)

24 Retrospective analysis of 4 years of QI data N= attempt complications 14.2% (95% CI12.4%-16.2% >1 attempt complications 47.2%(95% CI 41.8%-52.7%)

26 What are some things we can fix?

27 First pass success PGY-1 38% PGY-2 52% PGY-3 66% Anesthesia Resident 85% Higher year of training RR.74 95%[CI] P<.01 Anesthesia Resident RR.52 95%[CI].2-1 P=.03

28 Lessons People with more experience have better success

29 N=322 Anesthesia Residents out of OR intubations Complications decreased with attending Supervision 21.7% vs 6.1% P=.0001

30 Lesson Anesthetists are the experts

31 So.. How many intubations does it take to become good?

32 How many Intubations should you do to show competency A. 5 B. 10 C. 20 D. 30 E. >30

33 57 successful intubations to have 90% success rate Still improving into the 80s

34 472 intubations by 20 trainees (msi, RT, EMT) All pts prescreened to be easy intubations Analysis of data predicted 90% success after 47 intubations existing Direct laryngoscope intubation training..is inadequate for non-anaesthesia healthcare workers Emphasis should be placed on effective ventilation and oxygenation using BVM

35 Small number of ER residents (3) 342 intubations over 2 years 74.7 intubations to achieve 90% successful intubation (95% CI )

36 Lesson RT intubation competency programs are probably not adequate.

37 33 airway cases identified Identified contributing issues Lack of airway assessment Failure to alter technique when difficult a/w Lack of airway strategy Failure to alter failing technique

38 Lessons Assess Plan and communicate an airway strategy If it looks tough, do something different If something isn t working, don t do it again

39 With anticipated DTI 70% anesthetists didn t change technique > 60% progressed to CICV SGA regularly rescued failed intubation Transtracheal jet high complications rate of death when used as rescue

40 Lesson Change technique for difficult A/W Don t use transtracheal jet SGAs are pretty cool

41 How many of you regularly see DL fail during intubation and the second attempt is DL again?

42 When first attempt DL unsuccessful, repeated DL 80% failure rate. Recommend identification and detailing difficult A/W details

43 Lesson If it isnt working, don t keep doing it no matter how tempting Clearly identify Difficult A/W

44 Previous difficult intubation (DTI) 6 times more likely to be DTI again Previous failed intubation 22 times more likely to fail again. As a result of findings Denmark created database

45 Lesson Clearly identify people with difficult A/W Listen if someone says it was difficult

46 But I Gotta Intubate! It s an Emerrrrrrgency!

47 They Can Usually Wait Less than 1/3 of our pts were Emergent Intubations of Critically ill are usually urgent, not emergent (Griesdale 2011)

48 N=649,359 Favourable Neurological outcome; Intubation SGA BVM

49 N=649,359 Favourable Neurological outcome; Intubation 1.0% (95% CI 0.9%-1.1%) SGA 1.1% (95% CI 1.1%-1.2%) BVM 2.9%(95% CI 2.9%-3.0%)

50 Lesson It may be better to use BVM than intubate (at least in cardiac arrest)

51 But what if I can t manually ventilate them?

52 4 year observational study N=53, cases of impossible mask ventilation Only 19 of these were difficult a/w

53 Lesson Impossible mask ventilation is extremely rare. Even if you do meet them, they will probably be easy to intubate

54 N=128 Apneic oxygenation Decreased desaturation during intubation absolute risk reduction 16.7% P=0.016

55 Lesson Apneic oxygenation may further decrease your risk of desaturation during intubation

56 What if you put it all together?

57 Two phase Multi-center Use of Intubation Bundle Preoxygenation, 2 operators, RSI, Cricoid, EtCO2, Protective ventilation, Fluid loading N=244 (123 before, 121 after) life threatening complications 34%-21% other complications 21%-9%

58 Griesdale et al 2011 (unpublished) Use of a checklist Serious Complication

59 Lesson Use a checklist, they work!

60 307 Hospitals 4 Countries 1 year Prospective ICU, ED, OR Airway Cases: Death Brain Damage Unexpected ICU

61 NAP 4 4 Common themes identified 1) Lack of airway assessment 2) Lack of airway strategy 3) Avoidance of awake techniques 4) The failure to plan for Failure: repeated attempts using the same people/equipment

62 NAP 4 98/133 no documented airway exam 66 may be difficult -1 change in airway strategy needle Cricothyrotomy: Rate 64% (16/25) Failure Failure to use capnography implicated in 82% of ICU airway deaths and brain damage

63 NAP4 Recommendations Develop a checklist for intubation Standardize Difficult A/W equipment Including SGA and Aintree catheters Do more awake FOB intubations Investigate A/W critical incidents Appoint an A/W lead anesthetist in all institutions. Capnography is mandatory

64 NAP4 Reccomendations Identify Difficult A/W patients Establish good communication between ICU, ER, and Anesthesia Establish clear lines of communication to escalate A/W events to individuals with appropriate skills.

65 What have we done so far Difficult Airway Recognition Blue wrist band Blue sign for HOB Airway Alert form

66

67 24 hour a day response from a rover Anesthesiologist for difficult airways Empowered any member of team to escalate airway emergencies

68 ETCO2 monitoring at every intubation Standardize difficult intubation equipment Standardize intubation procedure Preprinted orders

69 Pre-printed Orders: Intubation Royal Columbian Hospital (trial) DRAFT Form ID: Rev: April 10 th 2014 Page: 1 of 1 DRUG & FOOD ALLERGIES Mandatory o Optional: Prescriber check (P) to initiate, cross out and initial any orders not indicated. 1. PREPARATION- PRE-INTUBATION Airway Competent MD, RT and RN present Airway equipment present and consideration for adjuncts discussed Planned strategy for intubation verbally communicated to all team members (see back) Airway assessment and positioning completed: Assess for contraindications prior to positioning (e.g. any cervical spine instability?)

72 So. Should RTs be intubating? If our competency programs are inadequate We often don t do enough intubations to maintain competency Dealing with failed A/W is beyond our scope We are unable to do awake fiberoptic intubations Open cricothyrotomy is beyond our scope Greater than one attempt significantly increases severe complications

73 So..Should RTs intubate? A. Yes B. No

74 How have the initiatives worked so far?

75 Difficult airway identification system Has been huge success. Every difficult airway (?) is being labelled and documented FHA is adopting system

76 Extubation of Difficult A/W Empowered RTs to refuse orders to extubate difficult airways Identified difficult A/W require anesthetist to be present for extubation

77 So, how has the order set worked? In 11 months we have had 17 uses of the order set Approx 10% usage

78 What about babies? Maybe RTs should intubate babies?

79 Neonatal ETI Data collection cards now kept in NICU Overall complication rates 54% Complication rates with 1 st pass success 29% Complication rates increase to 83% thereafter

80 Complications with Intubation

81 Maybe we suck at intubating babies?

82 5 level 3 NICUs One year study ETI attempts 203 patients

83 Neonatal ETI Low frequency, High-stakes events Success rates poor (at best 72%) 60% decompensation+esophageal Providers with more experience more successful

84

85 Going to get worse No routine intubations for meconium No longer ethical to practice after death Working hours for DRs reduced Reduction in invasive ventilation

86 50 ETI assessed Residents (25), NICU Fellows (13), RTs (12)

87

88

89 Why difference Adult to Neo Difficult airway uncommon Limited techniques and adjuncts Uncommon procedure even for Attending Physicians

90 What do you do if you cant intubate a neonate???

91 Telephone survey of all 59 level 3 NICU in UK 7% had CICV algorithm

92

93 Cautious Maybe Smaller, dedicated staff Take on the dedicated role Reasonable competency program
