BehindTheMedspeak: Pediatric MRIs will never be the same - thank God almighty!

My fellow blogging anesthesiologist Book Of Joe posted BehindTheMedspeak: Pediatric MRIs will never be the same - thank God almighty! and points to new motion-correction software available for MRI's.

" "I was quite dismayed when I read on and learned that, though the software and hardware upgrades required for MRI machines to create acceptable images with a moving patient have been available for a year, 'they are not used in all hospitals and clinics.'

It is inconceivable that any institution doing MRIs wouldn't immediately buy these upgrades.

The cost of a medical negligence suit resulting from a dead or brain-damaged child is astronomical, running into the millions of dollars; it dwarfs whatever G.E.'s charging for Version 2.0.

Talk about penny-wise and pound-foolish..." "

I agree whole heartedly.

Unusual Venue for a Tribute: iTunes Music Store

I ran across an unusual, but moving, tribute from a son to his mother. I say 'unusual' mainly because of where I found it--on the iTunes Music Store. I'll post it below for you to consider:

For those of you with iTunes, you can see the iMix.

RSS for PubMed Searches

Orac Knows points to a really nifty use of rss for those of us that use PubMed for literature searches called HubMed and use RSS. HubMed offers 'RSS feeds of literature queries - updated daily'. For example, I can enter a search string like 'liver transplant anesthesia' and get a nice list of hits on a web page. Encoded in the html of the page is the url for the rss feed of this search. Handing the html page url to your news reader/aggregator allows it to 'discover' the rss url for you. After that, your news reader will highlight any new references the search turns up.

'X' Marks the Spot. Or Does It? has details of a recently announced jury verdict in a case of wrong side surgery:

" "A Manhattan hospital and the chief doctor for the New York Rangers hockey team were ordered Thursday to pay a dance director and choreographer a total of $450,000 because the physician operated on the man's wrong knee.

The jury awarded the money to Douglas Hall, 43, who entered St. Vincent's Hospital on Nov. 30, 2001, for arthroscopic surgery on his right knee. Despite marking that knee with an 'X,' Dr. Andrew Feldman operated on the left knee. " "

Does an 'X' mean 'operate on this one' or does it mean 'do not operate on this one--operate on the other one'? I've seen a few patients write 'No!' on the non-operative side. We all got a chuckle out of it, but it worked! Rather than an 'X', the mark should be placed on and refer to the correct side--either 'R' or 'L'.

The rest of the article points out that the OR was also set up for the wrong side. Just another example of multiple failures being needed for a medical misadventure to occur. I'm sure there was no end of the 'blame game' going on for this one.

Why I Like Being An Anesthesiologist

I've tried to explain to people why I like being an anesthesiologist so much--with difficulty (unfettered access to narcotics, starting my work day at 07:30, having patients ask me if I'm a real doctor, oodels of respect from surgeons and nurses alike are the reasons that usually come to mind). I just ran across something on the web that really helps me understand why. Getting Back To Work: A Personal Productivity Toolkit at is an article about procrastination. Now, my favorite motto is 'hard work pays off after a time, but laziness pays off now,' so I was naturally drawn to this article.

The article describes the ideal work experience as being in a state of 'flow' and goes on to outline the kinds of tasks that make it more likely you'll be able to attain it:

  • Variety
  • Appropriate and flexible challenges
  • Clear goals
  • Immediate feedback
  • A sense that one's skills are adequate to cope with the challenges at hand.
  • A rule-bound action system
This is what the ideal job looks like. This job will resemble play, and will be addictive. As much as you can create work like this, you will be a happy person. As much as you can make your work like this, you will want to do it. "

Bingo! That's why I like being an anesthesiologist in private practice!

That's also why I like using Conversant to build web sites. When I'm working on a Conversant site, I often reach a state of 'flow.'

Google--Preventing comment spam

Google--Preventing comment spam:

" "If you're a blogger (or a blog reader), you're painfully familiar with people who try to raise their own websites' search engine rankings by submitting linked blog comments like 'Visit my discount pharmaceuticals site.' This is called comment spam, we don't like it either, and we've been testing a new tag that blocks it. From now on, when Google sees the attribute (rel='nofollow') on hyperlinks, those links won't get any credit when we rank websites in our search results. This isn't a negative vote for the site where the comment was posted; it's just a way to make sure that spammers get no benefit from abusing public areas like blog comments, trackbacks, and referrer lists." "

JAMA -- Quality of Cardiopulmonary Resuscitation During Out-of-Hospital Cardiac Arrest, January 19, 2005, Wik et al. 293 (3): 299

JAMA -- Quality of Cardiopulmonary Resuscitation During Out-of-Hospital Cardiac Arrest, January 19, 2005, Wik et al. 293 (3): 299 (free article)

Bottom line--it's hard to do it right. I have given chest compressions in the operating room with an arterial line in place so I can see what effect my compressions are having in terms of generating a pressure. Depressing the chest 4 to 5 cm is a lot, but that's the guideline, and that's what it takes to keep blood pumping to the brain. If you're going to the OR and know you're going to have a cardiac arrest, ask for me.

Grand Rounds XVII

Welcome to Medical Weblog Grand Rounds XVII with a theme of medical errors. One week is not a great deal of notice to make a topic-specific post (note that I didn't make one myself), but a 'thank you' goes out to those of you who did post on the topic. Near the end, I've included a 'roundup' of other posts.

If I missed your post, please accept my apologies...and forward it to A Chance to Cut is a Chance to Cure.

    2. "It's sort of like the approach that a family therapist takes. When a family presents for treatment, someone is always identified to the therapist as the bad family member. It's either a child with behavior problems or a dad who is drinking, or the like. But family therapists know that the "identified patient" is just showing that there is a problem in the family system. To stop the bad behavior or the drinking, you have to treat the larger problem.

      Likewise, doctors need to understand that the goal should be to identify the problem within the "hospital family" that leads to medical errors, instead of having an identified bad-doctor in the hospital family."

    2. "What are staffing ratios? It's different for each area of the hospital. ICU's are to have only one-two patients per nurse. Medical/Surgical floors are supposed to have only 6 patients per nurse. (I've worked on med/surg floors and have had nine patients.) The staffing ratios were supposed to be put into effect over the course of several years. This means that as of yesterday, January 1, 2005, med/surg nurses were supposed to be assigned only 5 patients apiece."
  9. The Write Wing: Medical Errors
    1. The Write Wing: Medical Errors
    2. "In the fast pace of the emergency room environment, there are very common mistakes involving medication orders. When orders are spoken, you need a nurse who will 'call back' your orders to you to confirm, and MOST ESPECIALLY when she is in doubt about the dosage or the route of a medication! It is NOT an affront to your ego, a statement of your competence as an MD, it is the job of any good nurse to do so. This is how a TEAM operates."

A satisfied but unspoken calm descended upon him as his mind sifted through the various circuits of memory stretching between the left and right sides of his brain. He told me of the best musicians he had ever played with, and it was like listening to a man recount the loves of his life. It was neither lustful nor corporeal, but rather experiential and otherworldly."

"I was utterly flabbergasted that a company could use such false and/or misleading statements this on a large AM station in order to sell a test whose validity had not yet been established for that purpose and that insurance companies didn't pay for. Concerned about the false information being promulgated several times an hour on his station, I politely wrote the program director and expressed to him my concerns that this ad was deceptive in exaggerating the shortcomings of mammography and the usefulness of breast MRI as known at the time."
  14. Hospice Blog: Why people like hospice
    1. Hospice Blog: Why people like hospice
    2. "So, why do people with a past hospice experience have a positive view of hospice? The answer, in my mind, is somewhat simple. When people stop me on the street tell me how wonderful hospice is and how much we helped one of their family members or friends, I usually say, “We’re the experts at the one thing that nobody wants to be an expert at.” I believe that simple statement is why hospice is so well received."

    2. "A 72-year old female comes into the clinic with arm pain. This occurred when she was shoveling snow on her porch, and was brought in by her family. The pain is described as dull and aching, worse when she was shoveling the snow, somewhat resolved on rest. She denies chest pain, shortness of breath, nausea, vomiting, fevers or chills."
  16. Different River: Medicare for All=None
    1. Different River: Medicare for All=None
    2. "The dirty little secret behind Medicare is that it works only because it does not cover every American. Part of the reason for this is that Medicare’s payment structure is designed to pay doctors and hospitals in such a way as to limit total spending, rather than to ensure they can break even. Clearly, they have to do better than break even to stay in business, and the people running Medicare know that. Medicare depends on the fact that there are lots of non-Medicare patients out there who (through their private insurance) can pay enough to keep the doctors and hospitals in business. This is called “cost shifting.”"

Triple Lumen Catheters Are Not Volume Lines

I brought a patient to the operating room recently who had a Type A ascending thoracic aneurysm dissection. She was bleeding into her pericardium and was in tamponade on arrival. She had a radial arterial line that wasn't (in an artery), and two triple lumen central lines--one in a femoral vein and one in an internal jugular vein.

I immediately thought back to my medical school days when I would see patients in the ICU with a GI bleed being transfused with cold, undiluted packed red blood cells through a triple lumen central line....and they were on vasoactive drips for 'hypotension.'

What's my point? Triple lumen catheters are long and narrow (especially compared to Cordis introducer sheaths or products like them made by other manufacturers such as Arrow). Remember the Poiseuille-Hagen equation shows that flow rate is directly proportional to the fourth power of the radius, to the viscosity of the fluid being transfused, and to the pressure gradient established and inversely proportional to the length of the tube. A 9 French introducer sheath can infuse fluid at about 1000 cc/min. Compare that to about 250 cc/min for the 14 gauge lumen of a triple lumen catheter. So it follows, then, that if you need to give someone fluid (like blood) fast, you infuse it through a fat catheter that is short, reduce the viscosity by diluting it and warming it (in the case of packed red blood cells), and apply some pressure by elevating it well above the patient or putting a pressure bag on it. Got it? Good! This might come in handy when you next see a hypovolemic patient...

Medical Weblogs Grand Rounds XVI

At Medical Madhouse today.

Next week, I'm hosting Grand Rounds right here on WakingUpCosts and I'd like to focus the submissions on the subject of medical errors. Other posts are welcome, of course, but if you've been thinking about medical errors (as I have), why not blog about that this week and submit it? Please add your suggestions as a comment to this thread or send an e-mail.

Does Race-based Affirmative Action Help Professional Students?

An article is about to be published in the Stanford Law Review that is already creating a great deal of buzz in the law community. UCLA Law School professor Rick Sanders has written "Systematic Analysis of Affirmative Action in American Law Schools" which argues that African American students have been materially and tangibly harmed by law school affirmative action policies (a summary is here).

" "In the case of blacks, at least, the objective costs of preferential admissions appear to substantially outweigh the benefits. The basic theory driving many of these findings is known as the “academic mismatch” mechanism; attending an advanced school where one’s credentials are far below those of one’s peers has a variety of negative effects on learning, motivation, and goals that harm the beneficiary of the preference. Over the past several years, a wide range of scholars have documented the operation of the mismatch mechanism in a number of fields of higher education. " "

Based on my experience as a medical student and then as a member of medical school admissions committees, these finding resonate with me. I hope that a similar analysis can be done for medical school admissions. More importantly, I hope we can have an open discussion focussed on what's best for the individual students.
