[i-eat-worlds]

I’d love to see more cricothyrotomies in whump.

Whether it’s whumper or caretaker, the fear of the scalpel as it hovers over whumpee’s throat. The way it slices through the cartilage. Is it during a chaotic rescue, as whumpee’s throat fills with blood, their last hope of making it out alive? Or is it one of whumper’s cruel games, to rob whumpee of control and stoke fear? Does whumpee know what is happening? Does whumper taunt them with the scalpel, relishing the terror in their eyes? Or perhaps, it’s caretaker, gently but quickly explaining what must be done.

Either way….

CRIC YOUR WHUMPEES!

Today I built four new cricothyroidotomy phantoms again. Now we have a total of six, so that our participants have the chance to practice the surgical airway [email protected] www.bso-akademie.de #docendodiscimus #cricothyrotomy #socialmediadivision #raiseyourhand #stopthebleed #stopthebleeding #bleedingcontrol #tccc #paramedic #veteran #veteranenabzeichen #emergencyparamedic #tacticalmedic #CPR #firstaid #survivaldeutschland #tecc #brotherhood #friendship #adventure #erstehilfe #paramedic #airsoft #combatmedic #notsan (hier: Miesau, Rheinland-Pfalz, Germany) https://www.instagram.com/p/CqBqlWLK449/?igshid=NGJjMDIxMWI=

hi!! i have two questions: 1) is it necessary to use an ambu bag/some other form of manual ventilation on someone after they've had an emergency tracheostomy, or is keeping the tube in the trachea open good enough? 2) if the answer is yes, and an ambu bag isn't available, is there anything that can be used/done instead? thanks for all you do!!!

When people say “emergency tracheostomy” they mean something called a cricothyrotomy. Both a tracheotomy and a cricothyrotomy are essentially the act of cutting a hole in the tube that air flows through to get from the mouth/nose to the lungs (collectively called the airway) when something is blocking the airway higher up. This allows that air to bypass the block and enter the lungs (the hole itself is called a tracheostomy or cricothyrostomy respectively).

The difference is the location of the incision and how quickly the procedure is done. In a cricothyrotomy, the hole is made in the cricothyroid membrane, a thin area of tissue without many important structures laying over it that could be damaged if they were hastily cut through. It is often done in an emergency department by a doctor that specializes in emergency medicine.

In a tracheotomy the hole is made slightly lower in the airway (in the trachea) instead of going through the cricothyroid membrane. It is a more delicate and permanent procedure that is often planned ahead of time and done by a surgeon that specializes in head and neck surgeries.

An emergency cricothyrotomy is temporary- essentially just to get air into the person’s lungs as fast as possible when intubation is not possible due to an injury or obstruction (see this video for how it is done). Usually a regular endotracheal tube (the kind of tube that is put through someone’s mouth when they intubate them) is placed through the incision. The person is then sent to surgery to correct the injury or blockage, or if not possible, to place a tracheostomy tube.

In theory, a person could breathe on their own through an endotracheal tube placed in a cricothyrostomy, the same as people normally would be able to breathe through a long-term tracheostomy. However, between the severity of the injury usually requiring them, the fact that the person has probably gone without oxygen for a while before this procedure is done, the fact that they were probably sedated/anesthetized quickly prior to the procedure (which could decrease respiratory drive), and the fact that it is harder to breathe through a tube than it is through an intact airway, the likelihood that they will need breathing support via a bag valve device is pretty high.

Now I get the feeling you’re not talking about something done in an emergency department. In that case, the procedure is done similarly but instead of placing the ET tube (which I assume your characters do not have), they’d just put something with a wide enough tube to keep the hole open. If they were not breathing on their own and needed breathing support after that, rescue breaths could be given by placing their whole mouth (or, if they have it due to the really likely possibility of coming into contact with blood), their CPR pocket mask or barrier device) over the incision to give the breaths through the cricothyrostomy.

II. Background

Cicothyrotomy is a life-saving definitive tool on the spectrum of airway management interventions

Indicated in a "Can't Intubate, Can't Oxygenate" (CICO) scenario

Indicated when other Advanced Airways have been attempted without success

Cricothyrotomy should not be considered a failure of airway management

III. Precautions: Difficult Cricothyrotomy (Mnemonic: SHORT)

Surgery (with midline neck scar)

Hematoma

Obesity

Radiation Therapy history

Trauma (with distorted Laryngeal Anatomy)

IV. Protocol: Preparation (Cricothyrotomy Tray)

Tracheal Hook

Trousseau Dilator

Scalpel (#11 Blade)

Tracheostomy tube (cuffed, unfenestrated, #4)

Miscellaneous items

Test cuff prior to insertion

Gauze 4x4

Hemostats (small, 2)

Surgical drape

Elastic Bougie

V. Protocol: Double-Setup with the CriCon Technique

Background

Indications

Levels

References

Dr. Scott Weingart on emcrit.org likens Cricothyrotomy preparedness (CriCon) to the old military DefCon system

Assign a Cri-Con level to and prepare for every Advanced Airway placement

Employ a second airway provider to stand-by at the neck for emergency Cricothyrotomy

Green (Cri-Con 5): All patients undergoing intubation

Yellow (Cri-Con 4): Anticipated Difficult Airway

Red (Cri-Con 3-2-1): Anticipated Failed Airway with no reserve for repeat intubation attempt

Have Cricothyrotomy kit available if needed (check stock)

Mark 1.5 cm vertical incision line with skin marker from Thyroid cartilage to cricoid (see below)

Move Cricothyrotomy kit to bedside

Prepare the neck with hibiclens or betadine

Make vertical incision

Open the Cricothyrotomy kit

Scalpel is ready to make incision

Feel the cricothyroid membrane

Perform circothyrotomy

See No-Drop technique as below

VI. Protocol: No-Drop Technique

Identify the landmarks

Mark the incision line with skin marker

Prepare the skin

Immobilize the Larynx

Vertical Skin Incision (superficial)

Horizontal cricothyroid membrane incision

Immediately place finger or Elastic Bougie through incision into airway to hold position open

Insert Tracheostomy tube

Confirm tube placement

Completion

Thyroid cartilage

Cricothyroid membrane

Cricoid cartilage

Draw vertical line down midline from mid-Thyroid cartilage to cricoid cartilage

Consider Ultrasound (linear probe) to identify landmarks when soft tissue obscures the cricothyroid membrane and airway

Antiseptic solution (e.g. Hibiclens, Betadine)

Lidocaine 1% infiltrated into skin and subcutaneous tissue down to cricothyroid membrane (in conscious patient)

Use "Laryngeal Handshake" method (Levitan, see EM-Crit surgical airway link below)

Hold Thyroid cartilage between thumb and middle finger

Slide down the Thyroid cartilage with fingers on either side

Place index finger on cricothyroid membrane (between the thumb and middle finger)

Make superficial vertical 2 cm incision

Incise in midline from mid-Thyroid cartilage to cricoid ring

Insert index finger to palpate cricothyroid membrane

Some providers skip the vertical incision if they can easily identify the cricothyroid membrane

They move straight to making a horizontal incision below

Reduces bleeding and time to "cut to air"

However, greater risk of straying off the midline

Make horizontal incision at lower aspect of membrane (avoids vessels at top of membrane)

Technique: Make stab incision through membrane

Blood and soft tissue shifting will quickly obscure landmarks (and will spray blood)

Posterior aspect of cricoid cartilage serves as a long backstop

Prevents knife from penetrating deep structures

Cut to one direction, rotate blade 180 degrees, and cut opposite direction

Hole must be wide enough to fit a finger, bougie and tube

Option 1: Bougie and 6.0 or 6.5 ET Tube rapid technique (scalpel-finger-tube)

Option 2: Tracheal hook and dilator

Immediately move to 6.0 or 6.5 Endotracheal Tube over Elastic Bougie (without inserting hook)

http://emcrit.org/wee/real-surgical-airway/

http://emcrit.org/wp-content/uploads/2014/08/EMA-Scalpel-FInger-Bougie.pdf

Insert tracheal hook

Insert Trousseau dilator

Insert through hook incision

Rotate hook so it retracts the upper membrane in cephalad direction

Dilator is inserted a short distance

Spread the membrane vertically

Consider first inserting Elastic Bougie as guidewire for the Tracheostomy tube (see above)

Consider 6.0 or 6.5 Endotracheal Tube in place of standard Shiley Tracheostomy tube

Insert Tracheostomy tube gently (avoid creating a false passage)

Use an ET Tube that is shortened to 11 cm (alternatively, 6.0 Portex cuffed trach tube may be used)

ET Tube is inserted only until balloon is completely inside incision, then inflated

ET Tube is more easily inserted and managed

Less interlocking parts than Shiley

Shiley diameters are not consistent and may not allow Gum Elastic Bougie passage

Rotate so tube is directed towards Bronchi

Remove dilator and hook

Inflate Tracheostomy cuff

Auscultate lung fields

CO2 Detector or Capnography (or consider esophageal detector in Cardiac Arrest)

Observe for subcutaneous Emphysema

Suggests paratracheal insertion via false passage

A Nasogastric Tube or Elastic Bougie inserted into tube will meet significant resistance if tube is mal-placed

Obtain Chest XRay

Secure tube in place

Tape (2 inch) split in half at each end and each half wrapped around tube (and other part of tape to chest)

Respiratory therapy may have more secure ways to fix the tube in position

VII. Management: Post-Cricothyrotomy

Consult pulmonology or anesthesia for controlled attempt at intubation from above (e.g. under bronchoscopy)

Consult otolaryngology for further management of Cricothyrotomy site

I just witnessed my first cricothyrotomy. Female, 37, down for an unknown time. Medics on radio report to the doc that patient's jaw is locked and presumably from rigor. They simultaneously report that the rest of the patient is flaccid and warm. ((Everyone standing around scratched their head.)) Medics asked if they had permission to call, but docs advised to continue with ALS care. Patient arrived in the STEMI Bay with the Lucas on. Again, no success was made in intubating. The attending decided on a cricothyrotomy. The resident tried several times, but failed to be successful. One of the medics stood by me and explained the whole procedure as it was happening which was hugely helpful to hear and see what was going on. Things were really messy with the repeated attempts to insert the tube, five or six tries getting nowhere. Unfortunately at 5:13am they called time of death. By this point, the color difference between the patient's face and body was incredible. Quite a learning experience in the trauma bay tonight for sure.

There's this person in my head.

He's brilliant. Capable. He can do needle decompressions and cricothyrotomies, he can run a code without freaking out. He's a really good paramedic. Maybe even a great paramedic. He's me. Only so much better.
