Latest / Style Points / Anesthesia for Pheochromocytoma with Erin Grawe
Transcript
- 0:00Hello and welcome to another episode of Style Points.
- 0:13Today I have the pleasure of speaking with Dr. Erin Growey about pheochromocytoma.
- 0:18Erin initially was one of the people who oriented me to my job here at the University of Cincinnati.
- 0:25Erin, thanks for joining us.
- 0:28Thanks for having me, John.
- 0:29This is great.
- 0:31I am really pleased to talk to you because you have a lot of experience in the perioperative
- 0:37space.
- 0:38Can you talk a little bit more about your experience with that?
- 0:40Sure.
- 0:41So my kind of growth and development through the field of anesthesiology has been a little
- 0:50bit unique.
- 0:51I finished my anesthesia residency and then followed residency up with a fellowship in
- 0:58critical care anesthesia and then cardiac anesthesia.
- 1:04So when I started my practice about eight years ago, I spent most of my days in the
- 1:11operating room or in our ICU, our surgical and cardiovascular ICU.
- 1:19And then really through my experiences just developed a passion for perioperative medicine
- 1:28and actually became very involved in our preoperative anesthesia evaluation clinic here at University
- 1:36of Cincinnati.
- 1:37It's called the Center for Perioperative Care or CPC, how most of us refer to it.
- 1:44And became medical director of the CPC for about five years and found that I ended up
- 1:53spending most of my time outside of the operating room rather than inside the walls of the operating
- 1:59room.
- 2:00I was spending most of my time either in the preoperative clinic or in the ICU taking care
- 2:04of patients postoperatively and really just enjoyed that spectrum of care for patients,
- 2:13being able to see them on the preoperative side of things, still being able to manage
- 2:18them in the operating room and then taking care of them in the ICU as well.
- 2:23And have really just developed my practice over the last eight years to kind of fit that
- 2:30model.
- 2:32And I think why I developed a keen interest in pheochromocytomas and their management
- 2:39perioperatively is because I think all of those phases of care are very, very important
- 2:48and really can influence the outcome of a patient after a pheochromocytoma resection.
- 2:54So really important attention to detail preoperatively and getting them optimized, their intraoperative
- 3:02management and ongoing diligence postoperatively can lead to a really positive and good outcome
- 3:10for those patients.
- 3:12Well, before we dig into the management of pheochromocytoma, I want to ask you more.
- 3:17We get to know your question.
- 3:19Let's say that you could have dinner with anyone in the world.
- 3:22It could even be somebody from the past or from fiction.
- 3:24Who would you have dinner with and why?
- 3:28That's a really good question.
- 3:32Interestingly, I think it would be Helen Keller.
- 3:42And the reason I say that, well, interestingly, I have a son who's in great school and he
- 3:48recently had to do a book report on Helen Keller.
- 3:52And I think almost all of us know Helen Keller.
- 3:55She was a woman that grew up in the early 1900s who at a very young age became blind
- 4:00and deaf.
- 4:02And when my son was doing this book report, it sort of led to him reading an autobiography,
- 4:09which then led to us as a family watching a movie about Helen as a young child and all
- 4:15of her struggles.
- 4:18So being blind and being deaf, having to kind of live in this very dark, silent world, I
- 4:26can't imagine how kind of lonely and isolated that must feel.
- 4:31But despite that, she had the perseverance and the strength to kind of overcome that
- 4:39and figure out how to communicate and not only how to communicate and interact with
- 4:45the world, but also to become a leader and an advocate and an author.
- 4:50And she's published and she would speak and she was an activist for patients with
- 4:55or people with disability with the help of her kind of lifelong teacher, Ann Sullivan.
- 5:00So I'd invite Ann Sullivan to that dinner.
- 5:04But just to meet somebody that had that kind of strength and perseverance would be amazing.
- 5:11That sounds like it would be very inspiring.
- 5:15What an interesting answer.
- 5:16Thank you for sharing.
- 5:17Yeah, well.
- 5:18Let's start off with pheochromocytoma.
- 5:23For listeners who may not be familiar with what it is at all, could you explain what
- 5:26it is and why it presents unique challenges for us in anesthesia?
- 5:30Sure.
- 5:31So a pheochromocytoma is a neuroendocrine tumor that releases catecholamines.
- 5:40So it's a tumor that develops in individuals about 90% of the time.
- 5:46It's an isolated tumor that presents around the third to fourth decade of life.
- 5:53More infrequently, about 10% of the time, it's a familial or genetic tumor.
- 6:02And sometimes even part of the kind of the umbrella of the multiple neuroendocrine neoplasia
- 6:08syndrome, the MEN type 2, if you all remember that from medical school.
- 6:12I have to say, I remember studying that as a buzzword for...
- 6:15Yes, exactly.
- 6:16... kind of memory trick to go along with that.
- 6:19Yes, exactly.
- 6:20So pheochromocytomas can be a part of MEN type 2 syndrome.
- 6:27But 90% of the time, they're an isolated tumor.
- 6:30And usually, 90% of the time arise from the adrenal medulla.
- 6:37And they are catecholamine secreting tumors.
- 6:41And a lot of times, they are identified in patients that have very malignant or severe
- 6:46hypertension.
- 6:49Because they either have continuous or episodic release of catecholamines, both norepinephrine
- 6:55and epinephrine, these patients oftentimes present with syndromes associated with excess
- 7:03catecholamines.
- 7:06So again, hypertension, sometimes kind of diaphoresis, flushing, arrhythmias, and even
- 7:15can develop some renal dysfunction.
- 7:20So why this presents challenges for anesthesiologists is that you are receiving a patient in the
- 7:28operating room who has for potentially years, sometimes maybe even decades, excess catecholamines.
- 7:40And what that does to your physiology and other organ systems management can be quite
- 7:46challenging.
- 7:47Absolutely.
- 7:48I have managed a few pheos in the operating room myself.
- 7:54And I remember each one of them individually.
- 7:57They are certainly cases to be remembered for the last hemodynamic swings that you see.
- 8:05So before we get to the operating room, let's talk about what we do for these patients in
- 8:11the preoperative space.
- 8:13For you and CPC, what does that look like when a patient gets referred to you with FIA?
- 8:18Sure.
- 8:19Well, my approach to them on the preoperative side of things kind of fits, I think, three
- 8:27buckets.
- 8:29Number one being how effectively is their hypertension managed and optimized?
- 8:38And I want to spend a little bit of time on this because I can't emphasize the importance
- 8:43of this enough.
- 8:45And this is usually done on a multidisciplinary level.
- 8:51So once a patient is diagnosed with a pheochromocytoma and the decision is made that this patient
- 8:59is appropriate for surgical resection, preoperative blood pressure optimization usually occurs
- 9:07on a combination of levels.
- 9:09At our institution, it's primarily managed by the patient's endocrinologist.
- 9:14And we're very fortunate at the University of Cincinnati to have a great division of
- 9:17endocrinology who are very proactive and aggressive about managing these patients preoperatively.
- 9:25So because these patients, again, live in this chronic state of excess catecholamide
- 9:32secretion, they all have a state of chronic hypertension.
- 9:39The most important or kind of the initial front line management for hypertension is
- 9:49alpha blockade.
- 9:51And you always want to start with alpha blockade before any type of beta blockade because you
- 9:57don't want unopposed alpha stimulation.
- 10:03So usually the first medication that's introduced to these patients, and this occurs anywhere
- 10:08from about two to four weeks preoperatively, is the initiation of an alpha blockade.
- 10:17And this can occur, or there's a couple of different options, I guess I should say, with
- 10:22regards to alpha blockade.
- 10:25There's a long acting alpha blockade that I think we're probably all familiar with,
- 10:29phenoxybenzamine.
- 10:31It's a long acting medication.
- 10:33It's a once a day medication, so patients are usually compliant with it.
- 10:38The downside of it is that it's not as easily titratable in the outpatient setting.
- 10:45More recently we're finding it's hard to get insurance approval.
- 10:49So the more short acting alpha blockers such as prazicin or doxicin is actually typically
- 10:56what we're seeing most patients come to us on.
- 10:59Even though those are TID medications, they're more easily titratable.
- 11:06The goal is to titrate those medications until the patient is normotensive essentially.
- 11:16And once that patient is normotensive without orthostatic symptoms—I think historically
- 11:22the goal was to titrate these patients all the way up to the point that they were getting
- 11:27really orthostatic on an outpatient level.
- 11:29We've found that sometimes that degree of alpha blockade can lead to post-op or acute
- 11:36kidney injury, but at least titrating them to the point that they are normotensive.
- 11:44If we find that tachycardia, which can happen with a lot of alpha blockade, occurs, then
- 11:52initiation of a beta blocker as a second agent is also very helpful.
- 12:01So when a patient arrives in our pre-op clinic, that's kind of the first and foremost thing
- 12:06that we identify or look to identify is how appropriately is their blood pressure managed.
- 12:15And so when they come into the CPC, we're doing obviously vitals, but also orthostatic
- 12:20vitals as well.
- 12:23And if we have concerns about their degree of hypertension or we don't feel like they
- 12:30are alpha blocked enough, then we're communicating that back with the surgeon as well as the
- 12:35endocrinologist who's managing them.
- 12:37And it's usually a conversation at that point on which medications to titrate to get
- 12:44them appropriately optimized.
- 12:46So really important communication with the endocrinologist and the surgeon preoperatively
- 12:50is important.
- 12:53We find that in our pre-op clinic, we're kind of like the final checks and balance of that
- 12:56patient before they enter the operating room.
- 13:00So having that communication is really, really important.
- 13:07So that was kind of one thing in the pre-op clinic.
- 13:11The first kind of aspect that we're looking for and evaluating for the patient.
- 13:16The second really is identifying any other comorbidities that can be associated with,
- 13:26again, potentially years, maybe even decade of pretty malignant hypertension related to
- 13:34that years of excess hypercatecholamine secretion.
- 13:39So a very thorough cardiac evaluation is really important.
- 13:46We always do an EKG to look for any sort of arrhythmias or ischemic findings on an EKG.
- 13:55A preoperative echocardiogram to look for any sort of cardiomyopathy associated with
- 14:02the pheochromocytoma is important.
- 14:08In kidney function or logic function, it's not uncommon that some of these patients may
- 14:12have had strokes in the past or developed some chronic kidney disease.
- 14:18And then the third thing we really look at, and this is for every patient coming through
- 14:21the preoperative clinic, is assessing functional status, any other comorbidities that we need
- 14:27to address and optimize to get the patient through a big abdominal surgery safely.
- 14:37And so those are really kind of the three categories of buckets of things that we evaluate
- 14:42patients for when they come in to our preop clinic.
- 14:46I like that you mentioned one of the very typical buzzwords associated, which is the
- 14:51unopposed alpha and we don't want the unopposed alpha.
- 14:54Can you talk a little bit about what that actually means and what the consequences would
- 14:59be if we decided to ignore that?
- 15:01Sure.
- 15:02That's a great question.
- 15:03So a lot of these tumors, like I said, they secrete catecholamines.
- 15:10And the vast majority of them, most of them secrete more norepinephrine than epinephrine.
- 15:18And if you remember back, going back to physiology and even pharmacology, norepinephrine is primarily
- 15:27an alpha agonist.
- 15:29Epinephrine, you see a little bit more of a balance between alpha and beta agonism.
- 15:34But if you think about what our alpha one receptors are doing, when those alpha one
- 15:42receptors are stimulated, you see a lot of vasoconstriction.
- 15:46So these patients live kind of in a very chronic vasoconstrictive state, which also leads to
- 15:56a relative volume contraction because you're going to have, if those blood vessels are
- 16:02constantly vasoconstricted and those patients are hypertensive, you're going to have a decreased
- 16:07amount of salt and water absorption at the kidney level.
- 16:12So these patients are dehydrated and very, very clamped down.
- 16:16So when we start an alpha blockade, that's really important to start relaxing those blood
- 16:21vessels.
- 16:23And at the same time, you want to, what we call salt expansion.
- 16:30So that when it's done on the outpatient setting is giving them salt tabs so that they
- 16:37basically reabsorb water, free water at the kidney level to kind of increase their intravascular
- 16:46volume by the time that they reach the operating room.
- 16:50If we ignore that concept and let's say as an outpatient started a beta blocker, then
- 16:59potentially you're going to have, you're going to block the beta effects, beta one and beta
- 17:07two effects.
- 17:09And then all of a sudden you're going to have an extreme, what we call unopposed alpha stimulation.
- 17:16So a very, very strong vasoconstrictive response and your beta blockers aren't going to necessarily
- 17:22touch that at all.
- 17:25So that can be problematic for the patient.
- 17:27Or if you started them on another agent, like a calcium channel blocker or something like
- 17:31that, you're really not addressing the fact that you've got high levels of norepinephrine
- 17:38in the system working on your alpha one receptors.
- 17:43So the whole concept of this alpha blockade is actually crucial for the management of
- 17:50these patients because of their high levels of circulating norepinephrine.
- 17:56So you actually wrote the intraoperative protocol pretty recently that we are using for our
- 18:03pheochromocytoma patients.
- 18:05So that makes you a great candidate to answer my next question, which is how do we manage
- 18:10these patients when they show up in same day surgery?
- 18:13Sure.
- 18:14I can't speak to being prepared enough.
- 18:20So the answer to that question is preparation, preparation, preparation.
- 18:25We're going to assume that this patient has been well optimized by their endocrinologist,
- 18:32by the surgeon and by our preop clinic.
- 18:36So they're going to come in on the, come into the hospital on the day of surgery.
- 18:43They will have hopefully taken their alpha blockade and their beta blocker.
- 18:48If it's the longer acting phenoxybenzamine, then perhaps we may have them hold it on the
- 18:53day of surgery.
- 18:54But if it's the short acting parazicin, then we'll have them take their alpha blockade
- 18:58and their beta blocker on the morning of surgery.
- 19:04All of these patients get a pre-induction arterial line.
- 19:07We want adequate IV access on these patients.
- 19:11And before you even see these patients in same day surgery, the setup in the operating
- 19:15room is extremely important.
- 19:18This is not a case that you just kind of have some sticks of phenolephrine laying around
- 19:24or maybe some push sticks of nitroglycerin.
- 19:25While you absolutely want those things, we have our plump pumps in the room primed and
- 19:32ready to go with what we call uppers and downers.
- 19:36So antihypertensives, short or very short acting, fast onset antihypertensive agents.
- 19:45And then we also have pressors available as well.
- 19:49Because we can kind of talk about how this surgery I feel like is actually two surgeries
- 19:54and one that you have the first part of the operation is where you have the tumor intact
- 20:01and still have ongoing release of those catecholamines.
- 20:05And then the second half of the procedure is you have once the tumor has been removed,
- 20:13you have a whole second half of the surgery in which you may have an acute drop in your
- 20:21catecholamine levels and you're kind of dealing with the hemodynamic consequences of that
- 20:25as well.
- 20:26I think the key word in what you just said is may have.
- 20:30I have certainly experienced piochromocytomas where after resection the blood pressure plummets
- 20:36and it's dramatic.
- 20:37But I've had other ones that really the blood pressure seems to stay high and I've
- 20:44actually taken patients to the ICU on downers instead of uppers as the literature will usually
- 20:51suggest that you need to be on.
- 20:53Can you explain a little bit about why we don't immediately see a drop in everyone's
- 20:58blood pressure after it's resected?
- 21:00Well, I think you bring up a good point that if you've taken care of one patient with
- 21:06piochromocytoma, you've taken care of one patient with piochromocytoma that they can
- 21:11all present and physiologically act a little bit different.
- 21:18So that's why preparation and being kind of prepared for any extreme is really important.
- 21:24I think one thing that's important to know is that every tumor is a little bit different
- 21:30and you will have tumors that are very high secreting tumors.
- 21:35And those are patients that they have really, really high levels of metonephrine or noremetonephrine
- 21:44preoperatively.
- 21:46Those are patients that you may experience more of a rocky road and they really need
- 21:55a lot of attention to preoperative optimization and you may have the really high catecholamine
- 22:04surges with induction and tumor manipulation as the surgeon starts to dissect out the tumor.
- 22:13And with the loss of those very, very high levels of catecholamines after the tumor is
- 22:17removed, those are patients that may become really hypotensive and unstable after tumor
- 22:22removal, especially because we ask them to take their predsense and their beta blockers
- 22:27preoperatively.
- 22:29Now you have on the other end of the spectrum, some tumors are not as high secreting as before
- 22:38and so they seem to have a little bit less of those fluctuations.
- 22:44And those patients may remain hypotensive even after removal because they didn't kind
- 22:50of live at a really high catecholamine secreting state.
- 22:54The second thing too is some patients may have underlying chronic hypertension in addition
- 23:01to their pheochromocytoma that was contributing to their hypertension.
- 23:05So those patients may also not drop too low after tumor removal.
- 23:12The third thing is that really adequate volume resuscitation preoperatively and intraoperatively
- 23:21with the salt expansion and volume resuscitation, that should continue intraoperatively as well.
- 23:29So really close attention to volume management will also help minimize those really low lows
- 23:36after the tumor is resected.
- 23:39So I think there's a lot of caveats and nuances associated with pheochromocytoma management.
- 23:47And as you said, it can actually present quite differently depending on the nature of the
- 23:54tumor and how well the patient was optimized and their other co-lubidities as well.
- 24:03Now when I get a patient that comes to same-day surgery and their blood pressure is 210 over
- 24:10120, a lot of times that's a signal to me that I need to talk to the surgeon about potentially
- 24:16canceling or postponing a case.
- 24:20What if one of these patients comes to same-day surgery and they have a blood pressure that
- 24:24is sky high?
- 24:26Is this a patient that you would consider going forward with as opposed to a standard
- 24:31patient or what's your approach to that sort of situation?
- 24:34Sure, that's a great question.
- 24:38In pheochromocytoma patients, if a patient presented to same-day surgery with malignant
- 24:45pressures like this, I would one, want to verify did they take their home medications,
- 24:50their alpha blocker, their beta blocker, any other antihypertensive medications that were
- 24:56prescribed.
- 24:57If they did and their blood pressure is that high, then that's an indication to me that
- 25:02this patient isn't appropriately optimized and I would be having a conversation with
- 25:05the surgeon about canceling the case and seeing if we can get the patient optimized.
- 25:12Occasionally, if they've come in and they've told me that they haven't taken any of their
- 25:18home medications, well then I'll give them medications and in same-day surgery give it
- 25:25about an hour, sometimes two hours if we have the ability to delay the case that long and
- 25:31see if the blood pressure has come down.
- 25:35But because we know that in this procedure there is such a risk for extreme hypertension
- 25:43with tumor manipulation, blood pressures starting off in that extreme are really quite scary.
- 25:54And we've had a couple of patients that for various reasons have come in with pressures
- 26:00that high and we've elected to cancel the case and take a different approach for those
- 26:05patients coming in for surgery.
- 26:09And I can think of one case that occurred maybe about three or four months ago who was
- 26:16a patient who wasn't English speaking and actually the language that they did speak
- 26:22was very hard to get a translator for.
- 26:26And so medical translation happened through one of the patient's relatives.
- 26:32So I think a lot of the medical communication got lost in translation.
- 26:37So we don't think the patient was as optimized as they should have been or could have been.
- 26:42And there was just so many factors that went into that.
- 26:46So ultimately with conversations between the endocrinologist, the surgeon, and the endoseologist
- 26:52when we had that experience of the patient showing up to same day surgery with malignant
- 26:56range pressures we decided to cancel the case.
- 26:59And when we came back to actually do the case a second time we pre-admitted the patient
- 27:04to the hospital a day before surgery.
- 27:08Actually it might have been two days before surgery.
- 27:10Make sure they really got volume expansion through IV fluids.
- 27:14We were able to really carefully titrate their medications while being closely monitored
- 27:20in an inpatient setting.
- 27:21And ultimately the patient had a very successful surgery and resection and very positive outcomes.
- 27:28But I think it kind of highlighted the need to kind of come up with some creative solutions
- 27:37for these patients to really get them optimized and how important that is.
- 27:43That makes a lot of sense.
- 27:45So let's talk for a little bit about creating your battle station in the operating room.
- 27:52You said you mentioned having uppers and downers.
- 27:55And I know that there's a lot of room for a lot of different types of medications to
- 27:59be used here.
- 28:00What would you personally choose in a patient that you're pretty concerned about?
- 28:06Sure.
- 28:07So let's talk about I guess our downers first because in the operating room those are potentially
- 28:13the first medications that you're going to need.
- 28:17In the room spiked on a pump I usually have two downers.
- 28:23At our institution we have the availability of clavitapine which is a relatively new diphenhydramine
- 28:33calcium channel blocker that is very short acting and very rapid onset and very easily
- 28:38titratable.
- 28:40So my personal preference is clavitapine along with nitroproside are agents that I have spiked
- 28:50ready to go ready to start infusing in the patient.
- 28:54In addition to that we have push doses of nitroglycerin available as well.
- 29:01I also have on the flip side because again after the tumor is resected I want to have
- 29:07pressors available.
- 29:08Sure.
- 29:09And the two pressors that we will commonly use is norepinephrine or levofed and vasopressin.
- 29:16I'll have both of those medications spiked and ready to go.
- 29:20In addition to push doses of epinephrine and phenylephrine and norepinephrine if we need
- 29:26it for kind of a quick boost in the blood pressure while the infusions kind of get to
- 29:31a steady state.
- 29:33So those are the medications that I have spiked ready to go.
- 29:36We have two fluid sets set up.
- 29:40I mentioned I always usually or almost usually always do a pre-induction A line for these
- 29:46patients.
- 29:47So your pressure tubing for an A line.
- 29:51If I'm worried about cardiomyopathy in these patients I will also do a non-invasive cardiac
- 29:58output monitor.
- 29:59We use a visual a or flow track here to help kind of really guide fluid management for
- 30:06these patients.
- 30:09There can also be fluctuations with the patient's blood glucose.
- 30:13There can be kind of a surge of insulin with tumor manipulation and there can be some hypoglycemia
- 30:20followed by hyperglycemia.
- 30:23So I have an insulin infusion but I also have dextrose available.
- 30:28The whole case is like a tale of two cities.
- 30:30You have two operations in one where you have a very kind of shifting physiologic experience
- 30:38at the beginning of the case and you have at the end of the case.
- 30:42And so emphasizing preparedness for both of those situations.
- 30:47Sure.
- 30:48That makes a lot of sense.
- 30:49So what would be your approach if during the surgery they're working with their instruments,
- 30:56they're watching what they're doing on the screen and all of a sudden you see massive
- 31:03kinematic shift on the monitor.
- 31:05You see crazy hypertension spikes up to 250.
- 31:09What's your first move there?
- 31:11Communication.
- 31:13Communicate with your surgeon what's going on.
- 31:15They're going to be obviously very hyper focused on their surgical technique and quick removal
- 31:22of the tumor.
- 31:23So telling them what's going on.
- 31:26A lot of times if they're at a place in their surgery or their resection where they
- 31:30can stop and let things settle out, they'll do that.
- 31:34So once you identify it, alert the surgeon and then initiate basically your antihypertensive
- 31:43agents either by infusion or push dose, usually a combination of both until you can kind of
- 31:50get the patient stabilized toward normal tens of range and then they can again start their
- 31:55resection and tumor manipulation.
- 31:57And hopefully at this point now that you have some antihypertensive circulating in the system,
- 32:04you won't have such a profound hypertensive response to surgical manipulation.
- 32:08So communication is really, really important in these cases.
- 32:14One thing that you also mentioned before was having adequate IV access on these patients
- 32:18and something that we've talked about before when you were writing the protocol was whether
- 32:23or not to put a central line in these patients.
- 32:25What do you think?
- 32:26Should we put a central line in every single one of these patients?
- 32:30I think the bigger question is who needs a central line ever?
- 32:36Sure.
- 32:37So when you think of the reasons why somebody might need a central line, obviously number
- 32:44one is adequacy of IV access.
- 32:47So if you have a patient come in who's got great peripheral IV targets where you can feel
- 32:56like you can get two or more large bore IVs, I'm talking about 16 gauge, 14 gauge IVs,
- 33:06then your patient may not need a central line.
- 33:10You want enough access to give large volume of fluids rapidly if you need to, transfusion
- 33:20if you need to.
- 33:22You want a reliable IV for your IV infusions.
- 33:28And this is kind of, I think, the crux of the question and every institution might be
- 33:33a little bit different and every provider might feel a little bit differently.
- 33:38If there's a possibility that they have to run a presser at the end of the case, norepinephrine
- 33:43or vasopressin, again, I want a large bore IV that I can do that safely with.
- 33:51I know that potentially I'm not going to be doing that for an extended period of time.
- 33:55I know that I'm, as a provider, one-on-one with this patient so I can kind of continually
- 34:01assess the adequacy of that IV.
- 34:03I want to make sure I can see that IV.
- 34:06So if the patient's arms are tucked or someplace that I can't visibly assess that IV, I might
- 34:13be more hesitant to allow pressers to run through the IV.
- 34:18But if I have a situation in which I've got great IV access, I think that the duration
- 34:25of infusion isn't going to be terribly long and I can see and assess that IV for a patency,
- 34:31then I feel comfortable doing this procedure with peripheral IVs.
- 34:36Now on the flip side, if any of those scenarios aren't met, then I have a very, very low
- 34:43threshold for putting in a central line.
- 34:45And I think most of our colleagues, to be honest with you, would just go to a central
- 34:49line like 100% of the time on these patients.
- 34:58At our institution, most of our ICUs, especially our surgical ICUs, will not run pressers through
- 35:07a peripheral IV.
- 35:09So even if I have a patient where I've managed them intraoperatively with pressers, relatively
- 35:16low dose pressers through a peripheral IV, if at the end of the case they still require
- 35:20those, I will put in a central line before bringing them to the ICU.
- 35:25So I want to say that you can do a pheochromocytoma case without a central line, but with an asterisk,
- 35:34and understanding that those are the caveats.
- 35:39And that also if you feel like you need a central line for hemodynamic monitoring, if
- 35:44you want to monitor a CVP, then obviously a central line is another reason, or doing
- 35:50that is another reason to put in a central line.
- 35:53That makes a lot of sense.
- 35:54I definitely agree with you that it's certainly up to the provider, but I think most of the
- 36:01time most of us will put in a central line, but I can imagine some exceptions as well.
- 36:07Moving on to the ICU, we drop off this patient, and some of us who don't work in the ICU
- 36:14like myself would forget about them forever.
- 36:16Not really.
- 36:18What kind of management would you be doing in the ICU afterwards for these patients?
- 36:23Well, if they have that very classic traditional response of hypotension and vasoplesia post
- 36:31tumor removal, then it's just going to be close management of their blood pressure and
- 36:38their pressors.
- 36:40That can sometimes last for up to 24 hours.
- 36:43But again, as you said, there are patients that come out even hypertensive, and you're
- 36:49titrating your downer, so to speak.
- 36:53So ongoing blood pressure management is really the crux of their care over the next 24 hours.
- 37:01I mentioned too, glucose management, it can be wildly variable.
- 37:07They can kind of have this rebound hyper insulin response where they get hypoglycemic and may
- 37:12end up on a dextrose infusion.
- 37:15That's very possible as well.
- 37:18So these patients continue to require a ton of vigilance over the next 24 hours postoperatively.
- 37:25And once they kind of have leveled out to the point where you can kind of get them off
- 37:31all of these like vasoactive drips, so to speak, then really the next step is from a
- 37:37kind of a longer blood pressure management standpoint.
- 37:41These patients don't require their alpha blockade anymore.
- 37:46Some of them may require nothing for blood pressure management as an outpatient.
- 37:51Some of them, again, have some underlying chronic essential hypertension that they will
- 37:55need ongoing management of.
- 37:58So figuring out where that patient settles into is important.
- 38:04And that occurs days, weeks, even months postoperatively.
- 38:09So not only just in the ICU is that important, but close follow up even after the patients
- 38:15left the hospital to figure out how this patient's blood pressure is going to be managed on an
- 38:20ongoing basis.
- 38:21Yeah, that makes a lot of sense.
- 38:24Well, to wrap up, I wonder if you could share with us some of your personal style points,
- 38:30particular things that you do that you think, believe contribute to your effectiveness,
- 38:35success in the operating room.
- 38:39Kind of unrelated, pheochromocytoma management.
- 38:41Just like a general approach that I take in my career, whether I'm in the operating room
- 38:49or I'm in the ICU or I'm in our pre-op clinic.
- 38:53And I would give this advice to every young clinician out there is it's not enough to
- 39:00identify problems, either with a patient or the system or your environment.
- 39:06You have to identify solutions.
- 39:08For you to be an effective clinician and for you to earn the respect of your colleagues,
- 39:15of surgeons, of hospital administrators, wherever your career may lead you, an effective way
- 39:24of doing that is taking the next step is to find a solution to whatever problem that you're
- 39:31dealing with and proposing that.
- 39:34Now, it has to be within your sphere of influence.
- 39:36You don't want to walk around telling everybody else how you think they should be doing their
- 39:40jobs.
- 39:41I'm glad you said that.
- 39:42But if it's within your sphere of influence and you identify a problem with a system or
- 39:50an environment that you're working in, then think about how to make it better.
- 39:54It's not like you said, you want to be the person that, you know, curses the darkness
- 39:59or lights the match.
- 40:01So find a solution and work with the people around you to make your, to make patient care
- 40:10safer, to make work a more enjoyable place for everybody, to improve efficiency.
- 40:17And I think that's probably the kind of the number one thing that I could, advice I could
- 40:24give to young clinicians is it's not just enough identifying a problem.
- 40:31It's living and owning your kind of world, your patients and the environment that you
- 40:38work in to create a better system.
- 40:40Well, Erin, thank you so much for joining us.
- 40:44I am really pleased that you agreed to come on as a guest.
- 40:47I know that myself and many of the department members that I talk to think of you as a big
- 40:52sister to the whole department.
- 40:55You certainly bring a lot of your own personality and style to the operating room and I appreciate
- 41:04you sharing that with us.
- 41:05Thanks so much for having me, John.
- 41:06This has been awesome.
