POTD: Emergent Trach Complications

 Most common Tracheostomy Complaints Include the Following:

o   Dislodgement

o   Decannulation

 

Equipment:

o   3 parts  (past photo)

o   Outer cannula (rigid)

  • §  Top portion of the trach is called the neck plate

    ·      On the right upper hand corner you will find all the information you need in terms of sizing

  • o   Size 4, 6, 8 is the measurement of the inner diameter

o   Inner cannula

  • §  Must be inserted into the outer cannula to be able to bag the patient or connect the patient to the vent

  • §  You do not need the inner cannula if the patient is trach to air

o   Obturator  

  • §  The most distal portion of the outer cannula is blunt and has sharp edges the obturator prevents you from causing any damage when inserting the outer cannula

Important things to know when you get a tach patient

o   Size ( 4,6,8)

o   Cuffed or uncuffed

o   Reason for Trach

o   Date of placement

o   Stoma healing roughly 7-10 days

  • §  Increased risk of creating a fall passage if you replace the trach within 10days

 

Uncuffed trach are mostly used in patients to allow them to speak. If you need to ventilate a patient you must have a cuffed trach

 

Step-wise Management  of Patient with respiratory Distress in the Setting of a Trach

o   Default action for all patients in respiratory distress is to bag the face and the neck

o   High flow or PPV

o   How to bag the stoma if the trach is dislodged

o   Pediatric BVM

o   LMA (inflate a size 3 or 4  LMA and seal it around the stoma)

o   Remove the inner cannula and clean it. Replace it with either a new one or the clean one

o   Insert a sterile in-line suction catheter

o   If you can only insert the suction 1-2cm your tube is either dislodged or obstructed

o   If suctioning fails will need to deflate the cuff and push it in further and re-inflate it

o   If deflating the cuff fails will need to remove the trach tube

o   Can now intubate through the stoma or oropharynx

 Laryngectomy patient:

o   Cannot intubate through the mouth must go through the stoma

 If inserting an ET tube into the stoma only go until you loose site of the cuff then stop and inflate. Very short distance the tube needs to travel for a trach compared to an oropharyngeal intubation

 Algorithm

o   Green Algorithm (patent upper airway)

o   Red Algorithm (laryngectomy patient)

Stop Giving Your Patients Oxygen!

Stop giving oxygen.

You heard me.

Sometimes it seems like every patient in the emergency room is wearing a nasal cannula. Sometimes they're wearing it like a headband, or a necklace, or sometimes it's just spewing gas next to the stretcher. (Pause for laughter.)

But oxygen, for those who do not *need* it, may be harmful.

ACS

  • The folks at UpToDate suggest only giving oxygen if O2 is <90% on room air.

  • AHA also says only if room air sat <90%.

  • In the UK, oxygen is only recommended if the room air saturation is < 94%.

  • This amazing post from Dr. Salim Rezaie shows there is no convincing data that oxygen helps patients who aren't hypoxic, and there is some signal of harm with increased troponin/CK in patients given O2! Are we worsening their MIs?

STROKE

  • AHA says no oxygen unless saturation < 94%.

  • Journal Feed talked about this RCT of 8,000 patients, those getting supplemental O2 had no benefit.

ACUTE & CRITICAL CARE

So what's the ideal saturation?

In our critically ill patients, it's reasonable to aim for a sat of 94-98% based on a huge retrospective study in Chest.


Drowning and Submersion Injuries

For today's POTD, we're going to talk about drowning/submersion injuries. Hopefully you don't have to take care of a jet-skiier that gets pulled out of the East river this weekend, but in case you do, here's some tips to prepare you!

Epidemiology: 20% of deaths involve children < 14 yo, a leading cause of death in children < 5yo, typically in swimming pools, bathtubs, buckets. 

History of seizures and cardiac disease increases the risk of drowning.

Bimodal distribution with second peak usually (80%) in males 15-25 yo, alcohol involved in up to 70% of cases. Typically rivers, lakes, beaches.

Pathophys: Fluid aspiration => loss of surfactant, pulmonary edema, hypoxemia from V/Q mismatch

ED Management: ACLS if in cardiac arrest, it is usually a respiratory arrest. Remove wet clothing and use rewarming techniques. Initial CXR often normal. Assess for signs of trauma. C-spine injuries are uncommon (<5%) but still evaluate for trauma especially if unwitnessed event. Intubate if O2 sat < 90% despite supplemental O2, PaO2 < 60, or PaCO2>50 as hypoxemia is the major issue. If able to protect airway, BIPAP for positive pressure.

Fresh water vs. salt water drowning distinctions do not matter much because you need to aspirate more than 11mL/kg of body weight to get blood volume changes and even more to get electrolyte changes. Most nonfatal drowning victims aspirate at most 3-4 mL/kg.

Meds: none really helpful, it is supportive care. Steroids and antibiotics have not been shown to help.

Dispo: admit if any symptoms on arrive to hospital, at least for monitoring. If asymptomatic after a near drowning, monitor for at least 4-6 hours.
