That is preposterousi really do believe ketamine is a hypnotic and not a pain medication

Anyone doing cpap during pump run?
Anyone else using ddavp fairly often?
What do you think about drawing fibrinogen and plt a little bit before coming off pump, in certain cases?
Tee for preserved ef cabg?
About ketamine: how many of you have actually had a small dose of ketamine ? At doses that don’t cause deep anesthesia , ketamine SUCKS to experience. It’s a very uncomfortable high unrelated to any “hallucinations”. I don’t give ketamine to anyone that’s not already out from some other hypnotic so that they can skip the acute intoxication and possibly have some of the post effects.
Same reason I don’t give IV lidocaine without heavy sedation first. 60mg of IV lidocaine SUCKS. It is not pleasant .
1) Never. Nope. Surgeons nearly unanimously want the lungs totally deflated during a typical case.
2) Only for ESRD, VWD. So not too often.
3) Not a fan unless there’s been a very long pump run, some preop coagulopathy or DHCA.
4) Almost never. I can get almost all the info I need from direct visualization, especially with the quick surgeons I work with now.
It’s heavily patient dependent. I’ve had all of these when I had my appendix out - Ketamine was particularly great afterwards (I tried to get out of the PACU bed and walk around...), and the lidocaine wasn’t bad at all. But I don’t extrapolate these experiences to my clinical practice much, that’s not wise.
Morphine on the other hand was horrendous.
but how do you know which sedative is causing which effect when you have never had them before and you had them all at once?
And I disagree that you dont extrapolate your personal experiences, personal experiences should be an eye opening experience for you and SHOULd change your practice, i used to poo poo toradol until I had it for a kidney stone when dilaudid wasnt cuting it (at 6mg) it was a miracle.. now i give it to everyone i can..
we are people who have had relatively clean lives and are responsible for forming opinions about giving drugs to people, any personal experience is worth a lot more than some academic study in my book..
I'm of the opinion that all cardiac cases with sternotomy / thoracotomy should get a TEE. This paper (Impact of intraoperative transesophageal echocardiography in cardiac and thoracic aortic surgery: Experience in 1011 cases - ScienceDirect) demonstrated a 6% incidence of TEE leading to either a minor or major change in the surgical plan across a variety of cardiac surgeries, i.e. picking up undiagnosed moderate AI and cardioplegia, undiagnosed MR, ASD, LAA clot, bad ascending atheromatous disease, etc. Even in pure CABG, it was still helpful at a high enough rate for picking up new intraop WM, post pump aortic dissection and unexplained low cardiac output syndrome.
Just last month my non cardiac partner had a routine normal EF cabg. Pt **** the bed about 10 min after the protamine. Turned into a whole thing, unsure if it was graft failure or protamine reaction. Back on pump, balloon pump, nitric, the whole nine yards. No echo probe or machine in the room when the event occurred. Has to go searching for one (since we share with cath lab) which delays any diagnosis. It's a rare event, but the risk of TEE probe insertion is so low that I'd rather always have one in case this kind of situation occurs.

I too think everyone who is going to get cannulated for bypass should have TEE. I also think anyone that gets cannulas should have a cerebral oximeter, but I’ll bever get support for that. How many massive strokes are attritbuted to aortic plaque or air but were really poor SVC drainage. How many of you monitor SVC pressure routinely? On all bicaval cannulations?
Personally I think the worst thing that can happen in heart surgery is not suboptimal repair or revasc but a big stroke.
We used cerebral oximeter routinely in residency. Except nobody did anything about a drop so it was a moot point.I too think everyone who is going to get cannulated for bypass should have TEE.

I’m not a cardiac guy, but at my shop the default plan for elective cardiac cases involves IT duramorph and extubating on the table.
Devils advocate ....
Undiagnosed moderate AI and catdioplegia:
- tte should theoretically pick it up and often the field and ekg can tell if you are distending and not getting an arrest , also moderate ai doesn’t mean antegrade wont work
Laa clot:
- I guess tee is a whole lot better , but if they had major risk factors they probably be on Coumadin for prevention, what’s the chance they have low risk and still have clot?
Atheromatous disease:
- most are coming with CT scan, and if scan does show or if it isn’t done they can use epiOrtic US which has data behind its use for cannulation
Asd
- I mean I guess any asymtpmatic congenital thing could be there, I’d assume tte is somewhat decent for picking up, when would you even fix it...pfo often missed but I believe in just a cabg unless septal aneurysm data doesn’t support going after it
New rwma
- ekg? see it sooner on tee vs ekg I guess, I’ve seen surgeons use some flow and Doppler interrogation when they worried about their targets or graft
Post pump dissection:
I’ve caught it before But I don’t see why epi aortic couldn’t do the same if cannulation was straightforward and you were worried about it
Low cardiac output syndrome unexplained or protamine reaction or something else
- agree it’s tough without a pa cath or tee to really know...
I’ve seen someone die from tee probe before that’s why I bring up the food for thought
If Risk of complication from tee probe > chances tee making meaningful difference then it’s worth a thought....not sure we have all the answers yet though
A whole lotta "ifs" in this post.
TTE should pick up a lot of things, but I live in an area where my average male cardiac pt is 5'8" and >230lb (female 5'3" and also >230lb lol), so the mileage varies quite a bit on what a TTE will actually pick up. Some of my patients don't even have a TTE available when they come to surgery (chest pain-> +trop -> cath with normal LV gram and LVEDP -> proceed to CABG), but I do review the images from the most recent TTE if a pt has one before I TEE them, and you'd be shocked at how much pathology can be missed or miscalled, especially when talking about posterior structures, degrees of valve disease and MAC, or things that require fine resolution.
Agreed, moderate AI doesn't automatically rule out antegrade. But if it was you on the table, wouldn't you rather the surgeon had some idea beforehand about the operative (not preoperative) degree of AI (and maybe a backup plan) rather than rolling the dice and seeing the heart blow up?
LAA clot without risk factors is rare. So are TEE complications. Very few CABGs where I'm at have gotten a CT scan unless they had a history or the aorta looked crazy calcified on cath. Regardless, CT won't pick up big, soft atheroma that well (which is really the kind you should be worrying about since surgeons can palpate calcium). Also, between residency, fellowship, current gig, and locums gig I've worked at 4 different hospitals that did cardiac in the last 5 years and I've seen only one surgeon do epiaortic one time. It's cumbersome and just not a thing at the places I've been.
Picking up RWMA with EKG? LOL. The surgeon may do flowmetry on the graft but that doesn't mean the graft is gonna remain great as the chest is closed and the thing kinks off. There's a reason a lot of fellowships instruct trainees not to take the probe out until the skin is almost closed.
Significant ASD (qp:qs > 2) should be fixed. TTE can miss these if the RA/RV isn't crazy blown up and they're not looking closely.
Using epiaortic to check dissection? Again, good luck getting the surgeon to do that. Half the time with CABGs coming off I barely get about 10 seconds to eyeball the heart before the surgeon is yelling "protamine???"
We used cerebral oximeter routinely in residency. Except nobody did anything about a drop so it was a moot point.
We used to do sufentanil bolus for induction followed by an intraop infusion but with the opioid shortage we’ve been doing most of our cardiac cases without IV opioids. Preop oral Tylenol, Neurontin and methadone. No OG suction before TEE. Ketamine GTT intraop. Precedex GTT after. It’s actually worked better than we expected without much change in pain after (anecdotally) and likely faster extubation times.
I do miss using sufentanil for induction (so smooth) but luckily there is still a little bit available for transplants or emergency/unstable cases.
Not aware of any data to support its use on ANY case.not sure there is any evidence that says routine use for basic cabg decreases stroke

I was talking about cerebral oximetry....based on numerous studies that have speculated on the purported reduction in perioperative morbidity associated with the use of TEE in cardiac surgical patients undergoing MV procedures [15, 20].

dont hold me accountable for defending these if they are junk

Yeah, me too. Surgeons want them for the ICU.9Fr IJ catheters and CCO PA catheters in every single patient.
Although competent ICU clinicians don't need the numbers to diagnose/treat, when you are relying on NPs/PAs to babysit the patient while you sleep, the numbers are useful.Yeah, me too. Surgeons want them for the ICU.![]()

i Go back and forth about the usefulness of PA catheters. Putting them in everyone has taught me that the echo is far from the final word in valve disease severity and I find that the information helps me be more sure about grading disease severity because it really helps you correlate and interpret echo findings
Another how do you do your average case...
I’ve slowly been changing things during my first year out based on stuff I see my partners do that I like...
One is US aline with micropuncture for all
My first pass success is 100% since switching and it doesn’t add more than 30 seconds since the probe and everything is already in there
I realize I’ll get harassed for this, but I’ll take it
I’ll also just use the use glidescope fromcthe get go with folks who have a sick heart and bad lungs with potential for airway or mask ventilation to be iffy....I figure why not make life simple since these guys won’t tolerate much anyways. Just sick of watching someone struggle then inevitably pt goes downhill quick and you are trying to retrace steps
This is a good thread. Especially for guys like me still changing the way they do things based on reasonable stuff that others do
Mine too. I don’t argue because they’re the ones that manage the patient post op and they’re usually at homeYeah, me too. Surgeons want them for the ICU.![]()
There really isn’t. The swans are usually for post opI will admit I wish I was better and did this more routinely. The more Sr guys in my group are just way quicker and better at using information from the swan.
Can you give specific examples for stenosis and regurgitation that you routinely use and feel might trump or carry more weight than tee.

You’re essentially doing a diagnostic right heart cath every case if you treat it that way so you can use the information and correlate it with your echo findings. It’s pretty useful for the tricuspid because hepatic vein flows are really variable compared to pulmonary vein flows and affected by many things. Catheter based RAP and V waves are helpful for differentiating significant TR and RV diastolic disease.
It’s similar for the left sided valves and PA pressures. I’ve had a few cases where the patients symptoms were surely from severe diastolic disease and not their valve.
It’s also interesting to note that you can have blowing flow reversal in the pulmonary veins and normal PA pressures. There’s a deeper understanding of real physiology to be gained from cathing people routinely
Can you expound a little bit on the variability of hepatic vein flows? My understanding was full systolic wave reversal was a pretty sensitive and specific indicator of severe TR
Sensitive not specific I believe...compliance and Rhythm on the right can give the reversal...I think but I’ll dbl check the guidelines that recently made this point
