Scott, great stuff as always! One tip to share and this is an old habit from anaesthesia training, I like to reinsert an OPG after intubation as a bite block to guard the ETT
Yep, a bite block is nice. If you are going to use an oral airway, critical to position it by the molars and not the incisors as patients have been known to chip a tooth when position up front. I tape to the ETT on one side of the mouth.
Speaking from ICU land, we don’t use OPA as a routine – causes too many mucosal pressure injuries and makes oropharyngeal suctioning and proper teeth cleaning difficult.
Management of biting in the ED/first stages of ICU should be proper analgesia/sedation; the only time I’ve seen tube damage was with attempting to wake TBI patients (always a fun job).
(Caveat: Reinforced tubes should always have either a properly sedated patient, be a nasal ETT or have a bite block insitu. If they manage to collapse the wire reinforcement via biting, it stays collapsed. Major pain.)
Yep, by the time they get to ICU, they better have had their sedation and analgesia optimized to the point where they are not going to clench.
Great tip on the reinforced tubes, I can see that being a nightmare.
Reinforced/flexible tubes are a problem for three main reasons. 1 – As mentioned above, once they have been deformed, they do not return to their previous shape, which can cause significant obstruction of the tube. 2 – The cuffs are usually high pressure, low volume cuffs, which can potentially cause musocal inflammation and ischaemia in the trachea. 3 – The tip of the ETT is often made of especially soft and compliant material to facilitate nasal intubation, and easier passage of the larynx when attached to a fibrescope. The tip usually also incorporates the Murphy eye. Once at body temperature… Read more »
Thanks so much for that, Gavin
Hello,
From my ICU expereince we don’t use OPA as bite blocks for the reasons noted above. On rare occassions we use bite blocks that slide over the tube.
The caveat about the reinforced or armoured tubes is an excellent point. Just seen an airway issue with a posterior fossa tumor patient that bent the armoured tube.
I assume the reinforced tube that comes with the iLMA could have the same issue?
Great stuff,
David

I don’t often use bite blocks, but when I do need one in the field I will use an OPA a size or two smaller than the patient would have needed inserted backwards. (The flange that is normally on the lips is just behind the teeth and the curved part is sticking up in the air.) I tape it to the ETT, with a tab for easy removal of course.
Hey Scott,
Not sure what your thoughts are on regular usage of a respirator filter. But for our local standard we also make sure we are using a inline filter so we decrease cross contamination and provider contamination. We acutally are lucky enough to use a HME/respiratory filter combo from Covidien (no conflicts).
all our circuits have two filters between the ventilator and the tubing. If you have yours on the Y, does this mean you resuse vent tubing?
I work pre hospital in a rural setting so we do not have vents available unless we are doing inter facility transports. Even though when we arrive at the hospital we have ventilators (we work closely with our facility’s) we may not have a Dr available after arriving in the ED for 20-30minutes(or longer) depending on time of day and unless a qualified paramedic or Dr that is comfortable with a ventilator is there they are not used and patients are ventilated with a BVM only(no attachments) for an unfortunate amount of time. Our hospital ventilators now that we have… Read more »
This sounds like one of the systems I used to work in… Is there any chance your agency would invest in PEEP valves for the BVMs? If not, can you tactically acquire some from your friendly neighborhood hospital? I share your frustration with a lack of vent training in EMS. I ran all of the ventilator education (both initial and continuing) at one of my jobs and I struggled with both the lack of background knowledge of our (non critical care) paramedics and the infrequency with which they managed vented patients. I believe, in the hands of an inexperienced operator,… Read more »
Rebecca I am acutally pretty lucky, were very progressive in the prehospital realm here. We have everything in the post minus the ABG, oral decontamination and cuff meter. But they are relative to our situation and we make do. I get alot of grief from our uppers over the christmas tree I make every time I set up a BVM. If any one is interested pre hospital tree from our evac ett up Inline Suction/MDI adaptor, Etco2, HME/Resp Filter, Manometer, BVM with peep. I digress.. My question was more to our hospital setting as we frequent are called in to… Read more »
This is great Scott! As far as filtration goes, is there a consensus on what type to use in ED as first line of defense within a Hospital. My recommendation has always been a N99 or N100, especially post SARS.
Agree 99 or 100 is the way to go.
Fellow RTs, help our friend Scott out… He’s a good guy, don’t leave him hanging in his ED without adequate RT support! Most of the steps he mentions here would be done by an RT as a matter of routine within seconds of intubation at my hospital, including the A.line and the intubation itself.
Unfortunately, the powers that be in my hospital haven’t invested in continuous capnography or subglottic suction ETTs.
Ahhh, Sean to work in a center with RTs like that is pure bliss.
Sean, remember that RTs are a very American creature. In Australasia/UK and I think Europe there is no such thing and all of what Scott has gone through is done by docs and nurses. Scott, when you talk about running to vent alarms like a cardiac arrest alarm, do you mean that you have ventilated patients who aren’t being continuously cared for 1:1 by an experienced doc or RN (or RT)? I must say I almost tune out ventilator alarms (indeed, I had the drager tone as my text message alert for a while) because in ANZ all ventilated patients… Read more »
Yep, I understand that RTs mostly exist in Canada and US, and that Scott’s talk may resonate more with docs and nurses that have to take care of the vent and airway as part of a much larger overall job. But seriously guys… get some RTs down under, it would expand my travel options 🙂 I would echo your sentiments about vent alarms to some extent. Most critical care vents have different tones for high and low priority alarms… I think there’s a happy medium between running to the bedside because the pt coughed and triggered an alarm and ignoring… Read more »
what you can insert an A line and perform RSI but dont have access to continuous capnography?
Sad but true. We have the colour change EtCO2 detectors of course for tube confirmation and in ICU we have one crummy handheld capnometer that mostly collects dust.
I get depressed when we get an EMS crew bringing in a pt and I have to sneak a glance at their monitor for EtCO2 before they get disconnected and hooked up to our monitors without that capability.
Sean,
I feel with you, mate! Not having cont. waveform EtCo2 in the ED is very frustrating and if not on the receiving side when I bring them in sometimes I wonder if not only we need “Upstairs care downstairs” but “Outside care inside”!
Dreaming of better managing critical patients in the ED…
not that rare!
On the subject of ETT securing in prehospital setting. This all comes down to simplicity and diligence. We use plain old cloth tape to tie knots and secure tube in my service. I do double ties..that is two pieces of tape with two knots each so there are two ties securing the ETT. I place an oral airway too to guard the tube. And the real key is to watch the ETT like a hawk and use waveform capnography. This is what sets a safe standard for ETT care in the prehospital setting. The commercial ETT holders are fine but… Read more »
Here’s a mnemonic that I made up a while back because I found that I was forgetting to do things after the intubation. I modified it a bit to include a couple of the things you covered in the podcast.
cheers,

good stuff
I’ve been using the subglottic suction devices for the past few months in my rotations at LAC+USC, though I have yet to see one on continuous suction. I have been hooking the subglottic port to suction port up to wall suction each time I perform inline suction, and even with pretty vigilant oral suctioning, I consistently get a bunch of nasty secretions up from the subglottic port.
For me, this shows that the vigilant oral suctioning alone really isn’t doing the job. The cost of these damn things is incredible, but they’ve made a believer out of me.
thanks for your sharing your experience, Geoffrey
Hello, I only have antidotal experience with subglottic suction ETTs (mainly the EVAC tube). But, from my experience they don’t work very well for a couple of reasons. 1) With very think oral secretions the subglottic suction line plugs up. The lumen of the suction tubing is too small. When you do suction the mouth you find the secretions that the subglottic suction ETTs is missing. 2) Staff keep cranking up the pressure on the subglottic suction and this cause tissue damage (due to reason #1) 3) If they work well and all the secretions are cleared the subglottic suction… Read more »
so we are seeing pros and cons for this device, thanks David
Hi Scott, and greetings from Chattanooga, Tn!
Thanks for the great podcast. I had a question about something you mentioned when confirming the ETT placement post-intubation. You mentioned an option would be to advance the ETT until you stopped seeing SLS on the left, then pull back a few sonometers. Is this method something that has been described in the EM literature? Thanks!
Yes, but I can’t recall the reference. Any help?
I have a couple of things to say
1) It is essential to remove the HME filter while giving nebs, otherwise it will be ineffective
2) Swab the port on the cuff with chlorhexidine before connecting it to the pilot balloon
3) I think it is ideal to take abg’s after 20 to 30 mins of fio2 change

3 excellent tips! I usually wait 20 minutes for PEEP changes. FiO2 can be seen in ~5 minutes.
Beg to differ with the sequence. Anesthesiologist for 40+ years. First step is ET CO2-not there, neither is the tube unless it part of CPR where levels may be nearly undetectable. The desire to believe in correct positioning is overwhelming but ET CO2 is THE reality check
Thanks so much for commenting. I hope I was clear on the podcast: these steps are post tube placement and confirmation. Levels are never undetectable on waveform capnography even during CPR. The location of ETCO2 in the post-tube package is for places using coloremtric for confirmation and then having to find/call for cont waveform for tube monitoring. Of course tube confirmation occurs prior to a post-intubation package.
It’s really great ..
Hi Scott, I’m an RT at a university/county trauma center in San Francisco and have been listening to your podcast for a few years now. I thoroughly enjoyed this podcast as it dealt with things we routinely do at our institution, and I only wanted to comment on the topic of ETCO2 and the importance of understanding the PaCO2-PETCO2 gradient, especially with the hypoperfused trauma/medical patient. Often, we (RTs) find ourselves asked by our anesthesia/EM colleagues to “aim for x ETCO2” and they request maxing out the respiratory rate to achieve this, and often time resulting in a considerable amount… Read more »
The fact that ETCO2 doesn’t = PaCO2 is a consistent meme on the podcast. Thanks for reinforcing this point yet again. The reason we are monitoring ETCO2 is for tube disconnection.
Noone has mentioned the most important thing in this post

I’ve got one. Great for cracking open a beer after a difficult case…
Bet that was a gift from Ron Walls 😉

Hi Scott, fantastic podcast. I practice as a critical care flight paramedic in Ontario Canada and this lecture (and indeed most of your lectures) is very much in keeping with our practice. I will be forwarding this podcast to our education department as I think it very nicely summarizes the many facets involved in post intubation care. In response to your tube securing question we have a few approaches that we use. Our call profiles are on scene trauma, modified on scene (pick up from er closest to the incident), or interfacility. I find no gross deviance between rotor and… Read more »
Yep, I remember the 2″ pants leg. Awkward to do in real time! I used to premake them, which at least saves time, but I am a huge fan of the commercial devices. Nothing more disheartening than finishing a 5 minute tape job and then finding the tube needs to be pulled back 2 cm.
Hey Dr. Scott! I love your podcast!! Just a quick note on your comments regarding cuff pressures following placing an ETT. For the last several years, I’ve used my own version of a “poor man’s manometer.” It requires no additional equipment and I have had great results. I am a flight nurse and paramedic. Obviously, adding additional equipment to our limited arsenal of airway equipment is limited. So here a poor man’s method of achieving 10-30mmHg in the ETT cuff… After passing the tube through the cords, begin ventilating the patient with a BVM or vent. Put your ear next… Read more »
Ray, It is a great tip. I’m worried that your method would guarantee that the cuff pressure is not too high, but it may be too low as it is basically obtaining the minimum sealing pressure.
Great summation. Confirms and reinforces actions I have taken as my standard practice from other sources. What was really cool for me was listening to the dominating the vent lectures and intubating metabolic acidosis patients about three times each. Now it is incorporated in both my practice and my teaching of medical students, MLP’s, RT’s and RN’s. Good stuff.
thanks so much, Kevin
Scott,
I work in both an aeromedical transport environment as well as at a quaternary referral centre in Canada. MY site uses EVAC tubes (subglottic suction tubes) routinely and overall we are quite happy with them. The only real concern is as you mentioned on the podcast, the outer diameter. These tubes can be considerably bigger than an equivalent sized inner diameter tube. Usually this is not a concern in adults but in children we have gone away from using them as it can be the difference between a tube that is almost a full size or more bigger.
thanks for the real-world confirmation, my friend
Do you normally start enteral feeding at a trophic dose in the ED? Giving the controversy of PPI with VAP and C. difficile colitis, it seems a better choice for preventing stress ulcer.
we haven’t, but it is always on my list of things to consider introducing.
Scott, great post intubation package. Like you, I’ve been through the era of umbilical and cotton tape to secure ET tubes. I couldn’t agree more with the use of commercial ET tube holders. Additionally, please consider the use of a hard cervical collar (Stiff neck, Miami J, Aspen, Philly) on any intubated patient in the ED, not just trauma patients. By controlling the head movement, whether onto a CT table or during the transfer for ground or air transport you significantly decrease the probability of tube displacement. I have used this for many years doing air transport and have never… Read more »
It’s a great point during transfers in-house and probably for when radiology is shooting their chest x-rays. I see the patients head flopping back and forth every time they shoot one.
Great podcast as always (yes I’m a little behind)! I’m going to try and get my residency to create a “post-intubation” order set for our EMR that will incorporate much of what you listed.
Question about lubing up the ETT cuff… is this commonly done? I’m a 4th year EM resident and I’ve never heard of this. I checked out the article and it looks legit, I’ll try it next time. To be honest I’ve often wondered why we don’t just lube the whole tube.
it gets done, but is low down on the priority tree and can’t be done ahead of time with current lubes.
