Introduction to ALS Sir Sandford Fleming
Outline Work Environment Scope of Practice Training Equipment Procedures How PCP/ACP Combos work What will be expected of you?
Work Environment Many services are up to 40% ALS Presents different challenges – Bags are different – Dispatched differently – Crew configuration different (>age) – Expectations for level of care higher – Closer scrutiny Potentially more stress for the crew Combined care (different attendant/driver roles)
Work Environment Legislation – Narcotics Check sheets Signatures DMA – Risk’s/benefit – Higher chance something will go much better or much worse
Scope of Practice Lots more drugs Lots more heavy things Special airway equipment Special features on monitor – Manual defib – Cardioversion – Pacing (transcutaneous)
Scope of Practice Manual Defibrillation, Pacing and Cardioversion Advanced Airway LMA’s, Lited Stylets BTLS, ACLS,PALS IV Therapy ALS Drugs plus Symptom Relief, Versed, Fentanyl Activated Charcoal CXR Interp Pentaspan
Difficult Airway Algorithm Need ETT Attempt #1 -Without sedation(crash) or nasal ETT Attempt #2- Midazolam 0.05 mg/kg Fentanyl mcg/kg Attempt #3(or RSI Direct) Lidocaine, (atropine) with midazolam and fentanyl (see above) and succinylcholine mg/kg Backup- Laryngeal Mask Airway, Lighted Stylet, Surgical Airway
Training Time lines – roughly 1 year for ALS Didactic –classroom time Clinical –practice in a controlled setting – OR – ER – MOP/SOP – OBS/PEDS/ICU – Other (Burn Unit, HSC IV Team)
Preceptorship/Consolidation Where it should all come together With a designated preceptor Gradual transition to full care
Equipment Airway- – Basic airway – Laryngoscope plus ETT for Intubation – Rescue Devices –advanced airway Lighted stylet LMA – Surgical –Seldinger vs Quik Trach Bougie
Procedures Cardioversion Pacing Sedation Vagal and CSM Manual Defibrillation IV Bolus and IV medication Other routes (PR,IN,IM,ETT,IO) Intubation Advanced airway Needle decompression IO Thrombolytics VAD Central access
CONTROL THE AIRWAY Airway Management Decision Process (Judge how aggressive you need to be.) -Time/Distance-Personnel-Equipment -Other Considerations?
CONTROL THE AIRWAY “Evaluate for signs of difficult intubation” (this may help in your decision as well) -Obesity-Small body habitus -Small jaw-Large teeth -Burns-Trauma -Anaphylaxis-Stridor
CONTROL THE AIRWAY The PCP vs. ACP airway decision may not be based on one single factor, but rather based on an overall assessment of many factors.
CONTROL THE AIRWAY Pre-Intubation -Prepare Equipment -Hyper-oxygenate
CONTROL THE AIRWAY Orotracheal Intubation Procedure Sweep Left and Look
CONTROL THE AIRWAY Backward, Upward, Right Pressure (B.U.R.P.) Find Your Landmarks

CONTROL THE AIRWAY Readjusting with Cricoid Pressure
CONTROL THE AIRWAY Common Provider Mistakes * Making a difficult intubation more difficult *Rushing *Poor equipment preparation *Suction (lack there of)
CONTROL THE AIRWAY What is your back-up plan today? prolonged BVM… another provider… a smaller tube… better lighting… additional suctioning…
CONTROL THE AIRWAY Helpful Adjuncts Gum Elastic Bougie

Nasotracheal Intubation Indications: “Patient still breathing but in respiratory failure and in whom oral intubation is impossible or difficult.” CONTROL THE AIRWAY
Contraindications: -Apnea -Resistance in the nares -Blood clotting or anticoagulation problems -Basilar Skull Fx (?) CONTROL THE AIRWAY Nasotracheal Intubation
Technique: -Prepare patient and nostril -Prepare tube -Insert on inspiration -Take your time Complications: -Bleeding STEP 4. CONTROL THE AIRWAY Nasotracheal Intubation

Laryngeal Mask Airway Developed in 1981 at the Royal London Hospital By Dr Archie Brain ALTERNATIVES TO ETI
Indications: -When definitive airway management cannot be obtained. (ETT) Not a substitute for definitive airway management Laryngeal Mask Airway STEP 7. ALTERNATIVES TO ETI
Contraindication/Limitations:-Obesity-Non-secure -Size based -Not a med route Laryngeal Mask Airway ALTERNATIVES TO ETI
Weight Based Sizing <5kg = Size kg = Size kg = Size 2.5 Small Adult= Size 3 Average Adult = Size 4 Large Adult = Size 5 Laryngeal Mask Airway ALTERNATIVES TO ETI
Average Adult Woman = 4 Average Adult Male = 5 Average Adult Male = 5 *If in doubt, check the LMA Laryngeal Mask Airway ALTERNATIVES TO ETI
Procedure: -Hyper oxygenate -Check cuff -Lubricate posterior cuff -Head in neutral or slightly flexed position -Insert following hard palate (use index finger to guide) -Stop when met with resistance -Let go and inflate cuff (visualize “pop”) -Confirm and secure Laryngeal Mask Airway ALTERNATIVES TO ETI
Air volume is variable depending on cuff size and individual patient anatomy General Guideline: Size 1 = 4 ml Size 2 = 10 ml Size 2.5 = 14 ml Size 3 = 20 ml Size 4 = 30 ml Size 5 = 40 ml Laryngeal Mask Airway ALTERNATIVES TO ETI
Common Provider Problems: -Failure to seat properly -Sizing difficulties -Aspiration Laryngeal Mask Airway ALTERNATIVES TO ETI
Why – Unconscious / unresponsive patients without gag reflex – Blind insertion technique – Alternative to E.T.T. Known Issues – Obtaining proper seal / placement – Is NOT a medication route for Endotracheal drugs – Multiple sizes, based on height, also multiple cuff volumes – Contraindications Responsive patients with an intact gag reflex. Patients with known esophageal disease. Patients who have ingested caustic substances.
User Tip The key to insertion is to get the distal tip of King Airway around the corner in the posterior pharynx, under the base of the tongue. Experience has indicated that the lateral approach, in conjunction with a chin lift, facilitates the placement of the King Airway. Alternatively, a laryngoscope or tongue depressor can be used to lift the tongue anteriorly to allow easy advancement of the airway into place.
Insertion #3 As the King Airway is advanced around the corner in the posterior pharynx, it is important that the tip of the device be maintained at the midline. If the tip is placed or deflected laterally, it may enter into the piriform fossa and the tube will appear to bounce back upon full insertion and release. Keeping the tip at the midline assures that the distal tip is properly placed in the upper esophagus.
Insertion #5 Air Volume Required for Cuff Inflation: – Size #3: 55 ml – Size #4: 70 ml – Size #5: 80 ml
Insertion #6 Attach Bag While gently bagging, simultaneously withdraw the King Airway until ventilation is easy and free-flowing. Can the King tube device be used for PPV? Yes, in unresponsive non breathing pts
Is there an optimal head position for insertion? – Sniffing position, but the head can be in neutral position. – For obese patient’s, elevation of the shoulders & upper back should be considered. How long can the King tube be left in place? – Up to 8 hours. For longer procedures it is important to monitor& limit cuff pressure to 60 cm H20 or less. If my patient needs to be on a mechanical ventilator, do I need to replace the tube? – Due to the King tube’s improved ventilatory seal, it is less frequent that the tube needs to be exchanged compared to other supraglottic airways. Can a laryngoscope be used? – Yes, but it is not routinely used. It may be used by the inexperienced user, or difficult airway. What volume of pressure is needed to properly inflate the cuffs? – The least amount needed to create a seal at the desired ventilatory pressures. Each tube size is different What reference point for the centimeter depth markings on the tubes? – The cm markings indicate the distance from the distal ventilatory opening. The markings serve as a visual reference after placement and can be used to document insertion depth.
Indications-Obstruction -Facial Trauma -Intubation or other alternatives impossible -Trismus (clenching) ->8 years old (for open procedures) SURGICAL AIRWAYS LAST RESORT!
SURGICAL AIRWAYS -Vertical Incision over membrane -Pierce membrane in horizontal plane -Open and spread to insert 4.0 or 5.0 tube -Secure tube in place and ventilate
Needle Procedure: -Identify Cricothyroid membrane -Pierce at 45° angle -Place catheter or styllette -Advance dilator per manufacturer’s recommendation SURGICAL AIRWAYS Needle Cricothyrotomy
WHY AN ALGORITHM? 1.Step by step process in order 2.Start simple and work up 3.Alternatives 4.Be sure 5.Get it done
Procedure for Intubation Preoxygenate with 100% (may not need to bag) Prepare equipment (SLOPES-M) Hyperextend –Sniffing position Insert larygoscope into R sweep tongue to left Look for view Insert ETT to 1-3 cm beyond cords Withdraw largy Remove stylet inflate cuff with 5-8 cc air Auscultate neck, chest x 4 Secure ETT Document cm marking and reevaluate often
