I asked for suggestions on a strange EKG I snagged at work here in this post.

Many good suggestions, and a couple did guess correctly:   it is artifact.  I know, all that build-up for nothing, so disappointing, right?

The night I grabbed this though the patient had been admitted earlier on shift and had been in normal sinus rhythm since arrival.  This popped up and the tele tech asked someone to see what was going on as it was a retty major shift from the baseline.  It wasn’t obviously artifact, but very different from previous.  So we go down the hall and into the room and are greeted with the patient laying prone on her bed, tele leads and box squished under a rather substantial girth.  We convinced her to roll over and her tele returned to normal.

Just a little example as to how even artifact can look like something (or nothing at all) and why we as nurses should always remember that when something looks out of normal, we need to check it out.

I grabbed a cool strip this week but am heading out of town and won’t be able to post it until next week, but trust me, it’s a keeper.  Have a great weekend!

2nd Degree AV Block, Type I

Otherwise known as Wenckebach, or perhaps my favorite of the AV Blocks.  It has a certain je-nes-sais-quoi to it.  It is dynamic, but rather non-threatening.

The classic definition of 2nd Degree AV Block, Type I, is an increasing PR interval until a QRS complex is dropped.  “Longer, longer, drop, you’ve got yourself a Wenckebach” is a nice little mnemonic to remember when determining the rhythm.  Starting from the 4th beat in on the strip, you can see the PR interval goes from .24s, .26s, then .36s and a complex is dropped in the next round.  But you ask, where is the P wave for the dropped complex?  It’s buried in the T-wave from beat #6.  One other identifying feature of Wenckebach is that the P-P interval remains constant, in this case .64s, and the R-R interval lengthens as well.

Normally, this is a problem with the AV node, although there are some occasions where it occurs below the node, in the His-Perkinje fibers.  Occasionally you will get wide and bizarre QRS complexes with both above and below the node eitilogies, but more commonly narrow complex QRSs will be the norm.

Causes can include drug induced, from beta and calcium channel blockers, digoxin and amiodarone, also in cases of acute myocardial infarction (most commonly inferior wall).  Unlike Type II block which can evolve into 3rd degree block, Type I does not evolve into anything worse on its own.  Patients are rarely symptomatic just from the rhythm, and symptoms are usually a result of the precipitating factors. Unlike 3rd degree block, there is not much for us nurses to do except to monitor the patient.  As these folks are usually asymptomatic, it’s all we can do.  Past that, if symptoms are present, we can treat the symptoms.

And just because we’re talking Wenckebach, I have to include the classic YouTube gem:

Angiography: Live and In-Person

BBC NEWS | Health | Watch an emergency heart procedure

This is far too cool.  Patient is a 36 year old male, with a blockage of his RCA (according to the cardiologist). Risk factors?  Smoking. I lived in England for 3 months and am sure that smoking was not the only risk factor…but.

I wish they had displayed a copy of the EKG, but I would venture to guess there was some ST-segment elevation for them to rush him back to the cath lab so quickly.  They show a fluoro shot of the dye being injected then stopping, which gives a great visual representation of what is going on.  You can see how it is pretty much totally blocked.  Then they also show a fluoro shot prior to stenting where you can see the narrowed lumen of the artery. Unfortunately, these shots are pretty much fleeting in nature so to get the best view you would have to pause the video, which I highly recommend.

It’s fun, especially when the patient has a bit of a reperfusion arrhythmia!

Just Bizarre

Really?

Really?

Yessiree, I’m gonna’ get me some chicky chicky boom boom for dinner tonight.

As I had been out imbibing adult beverags with work colleagues earlier in the night, this sounded, well, near-delightful.  Luckily for me, cooler heads prevailed and there was no chicky chicly boom boom bought.  More than anything I just love the name.  AlthoughI wonder if that is a code name for certain acts…

Junkfood Science: National Patient Registry

Junkfood Science: National Patient Registry

The article explores the various legal and ethical pitfalls associated with EMRs…and it’s incredibly fascinating.  And it is a little scary, to realize that the creation of a national database would have far reaching effects onto the delivery of care and the provisions of privacy (or lack thereof).  One thing that struck me was the discussion of HIPPA and privacy, citing Supreme Court dialogs about the privacy of a persons’ medical record.

Being involved in an EMR transition project it brought up things I didn’t really consider and it is great food for thought.  It’s heavy reading but well worth it.

Targeted Advertising

I was watching the evening news tonight through heavily lidded eyes, but something very evident occurred to me:  people my age don’t watch the news.

How did I figure this out?  Commercials.  During 1 break that I was a little more cognizant for I saw a commercial for Plavix, Miralax and CVS pharmacies.  Not many folks in their 30’s need to take anti-platelet medications.  Sure some need to keep the GI tract moving and we all need a place to pick them up for sure.  But the general bent to these few commercials I was coherent for were obviously targeted to a older demographic.

Just a random observation.  I was really watching the evening news to compare broadcasts, NBC versus BBC America.  The depth and scope of coverage between the 2 was very different, vastly different.  Once again, targeted.

Making the Transition

Jerry had been on our floor for a little over a week, maybe a bit longer.  And he wasn’t getting any better.  In fact each day he seemed to get worse.  Small gains would be erased by further declines.  The anitbiotics weren’t doing their thing.  He was lucky to keep his O2 sats above 90% even on 10L high-flow nasal cannula.  It seemed like all he had to do was turn his head and he would de-sat into the low 80’s and take 10-20 minutes to come back up.

Unfortunately for Jerry his run with usual interstitial pneumonia was nearing its close.  His lungs were so scarred and fibrotic that there was nothing we as health-care providers do, except to place him on long-term ventilation, something which he had frequently and definitvely said he did not want.  One day he made his decision:  he was going to die,  Jerry wasn’t my patient, but I had interacted with him, albeit briefly, but understood from those interactions that this was a man who knew what he wanted to do and to continue living like this was not one of those.

I arrived at work the other night and the day charge nurse said to me, “We’re going to help Jerry die tonight.”

“What do you mean?”  I asked.

“He made the decision that he’s going to take off his oxygen and let nature take its course.” she said.  “But we’re going to make him comfortable and treat his symptoms.”  she finished.

“So everybody is on-board with this?  They’re not going to ry to change their minds half-way though?”  I asked.

“No.  The family is here, they’re in the process of saying good-bye.  Even his doc, who came out of the room crying today after he made his decision, is behind him.  I think everyone knows what he wants and are accepting that.  To help with that though I did staff you up a nurse.”  she said trying to put a spin on it.

I was still processing the idea.  I know that we’ve had comfort care patients who we let slip away, but never had someone who was completely lucid and in control of their faculties tell us to let them die and for us to actively help him make the journey.  In a strange way I was almost proud, can’t really find a word that describes how I felt, of Jerry for actively deciding how he was going to end his battle.  Instead lingering in an ICU, hooked up to a ventilator with nearly no quaility of life, he decided to take matters into his own hands and say, “This is how, this is when it is going to happen.  Finally, I’m in control.”

The nurse who had taken care of Jarry for the previous couple of nights was back again.  I hoped that she would be willing to take this on, but I knew she wouldn’t refuse, even if she was ucomfortable.  I saw her as she left the locker room and pulled her aside.

“I have to talk to you about tonight.  Jerry is planning on dying tonight.  I thought since you have a relationship with him, having taken care of him for the last couple of nights, you should get the assignment.  He’ll be your only patient and I’ll be your back-up and runner.  But, you have every right to refuse this.  I can’t force you to take this on.”  I siad as I laid out the situation.

“No, I can do it.” she replied.  “We don’t have that great relationship, it’s not like we’re friends, but you’re right, he knows me, is comfortable with me and I think that would be most appropriate.  Besides who else would step in?”

“Me.” I said.

“No, I’ll do it, what is going to happen?” she asked.

“Basically he’s going to let you know when to take his oxygen off and let things go from there.  You have medication orders for anxiety and dyspnea, so you can keep him comfortable and peaceful.”  I said.

We went off to start the shift and get things going.  She came up to me a little later and said, “I just talked to the doc who is covering tonight and he explained everything to me.  He even asked me if I wanted him to stay…it was a little surreal.  He did give me his pager and said if I wanted help, or needed support, he’d be willing to even come in to help.  Right now family is in saying their good-byes.  I’ll let you know when we decide to start.”

A little later she started.  She spent hours at his bedside, sitting with family and him reminiscing, learning about Jerry as he slowly started to slip away.  She would turn down his oxygen, give him some meds and wait for awhile and do it again.  About 1am she came out to both reload and take a break.  She said, “He’s hanging on.  He’s kind of Cheyne-Stoke-ing, real shallow, so when his family slipped out awhile ago I checked some vitals, he was 50/30, sats of 35%.  The doc had said it would be fairly quick, but I guess he’s hanging on for something.  I feel like there’s something else I should be doing. I mean, I’ve never done this before.  Is there something I’m missing?”

“I don’t think so.” I said.  “Maybe he’s not quite ready to let go.  Maybe give him anothe dose and let him sit with his family alone for awhile.”

And that’s what she ended up doing.  He had started to gasp a little so she gave him a dose and then left the room.  Sure enough about ten minutes later she went in to check and the family told her he was gone.  Normally we call the houe docs right away to pronounce, but with family at the bedside I decided to give them some time.  In the end we called the doc, who was a bit perplexed about why we called him, even more so why Jerry had decided to do this, but came and did his part in the end.  As part of protocol I called the attending who had told us o call if we needed anything to inform him and he asked how it went and if he was comfortable to the end.  He cared enough about Jerry to give him the dignified death he deserved and make sure it wasn’t a traumatic death  and he did a good job.

Helping Jerry make the transition was strange.  So often we’re going for the opposite, even when people are at the end we try to prolong life as much as we can.  But Jerry didn’t want that.  He didn’t want to live out the rest of his days on a vent, with lines and tubes coming out of him.  He chose how he wanted to go.  And that’s so rare.

Funny Quote of Last Night

“Who cares about HIPAA anyway?  The FBI is listening in on all of our phone conversations so there’s no confidentiality anyway.”  said by the self-confessed ultra-liberal near-socialist float pool nurse.  I’m thinking about getting her a tinfoil hat and a prescription for Haldol the next time she works with us.

It was either that or, “banan-anan-anana..” as uttered by the dude with horrid expressive aphasia.

Real posting to resume shortly.

Weather Wimps

For a place with such relatively mild weather, we here in Oregon tend to complain a little too much about the weather. I mean really, it rarely snows, it rarely gets over 100 degrees, no tornadoes, no hurricanes, but let me tell you, when something happens it’s like the Apocalypse.

Last month, we had a snowstorm.  Actually several snowstorms, that left at most 16″ of snow over the course of several days.  Of course leave it to the news to label this phenomenon of the *cue dramatic music* Arctic Blast 2008.  Yes, it was a mess.  Icy roads, bitter cold with a biting wind and the town acted like we were transported to the Arctic Circle.  What made things worse was the hysteria stoked by the news media and the inability of our local governments to effectively manage the roads and related infrastructure.  I lived in Flagstaff for 3 years and had several times where we  got over a foot of snow in less than 12 hours, but the town shut down only once and that was because we got 3 feet of snow in a 24 hour period.  That really is near cause for hysteria.  But the only people in hysterics were the tourists from the Valley of the Sun.

But it’s always the same.  Whether it is “Fall Floods ’07”, or “Heat Wave 2008”, “Arctic Blast” or the soon to come “Floods of 2009” on the news media whips us into a frenzy.  For days on end the local channels had nothing on but news, relating the same stories ad nauseam and bringing the dire reports of more nasty weather to come. All it takes a little change from the normal for them to start the dire warnings.  One anchor in particular is never happy with the weather.  When it rains a lot she complains about the lack of sun, but when it has been sunny for a long time she complains about the lack of rain.  She always has a snarky comment about the weather.

But I love it.  I was out in the weather on my bike nearly everyday of it.  I rode to work all but 2 days of the storm that I did work.  My co-workers looked at me in disbelief when I walked in head-to-toe in my foul weather gear.  But really, it was just another day.  No weather wimp here!
