Effects of acupuncture on pain and inflammation in pediatric appendicitis

A paper [full text here] from The Journal of Alternative and Complementary Medicine says that "acupuncture may be a feasible and effective treatment modality for decreasing subjective pain and inflammation" in pediatric patients with appendicitis.

They studied six adolescents with appendicitis and administered acupuncture for pain control prior to surgery. Pain was assessed using three analog scales, and inflammation was measured using serial white blood cell (WBC) counts and C-reactive protein levels (CRP). CRP is a nonspecific indicator of inflammation in the body.

Figure 2 from the paper summarizes the results.

You can see that after 20 minutes of acupuncture, all three pain scores and WBCs declined. However, CRP continued to rise. Conspicuously absent from the figure and the text of the paper are any statistical analyses. This is due to the lack of a significant difference in any of these values because of the limited number of subjects studied.

A new surgeon confronts self-doubt

A chief resident about to graduate wrote the following to me:

I just read—twice—The New Yorker's review of Henry's Marsh's [a renowned UK neurosurgeon] memoir you tweeted about. Wow.

It seems like he is grappling with so many of the things I'm feeling now, as I'm trying to sort out if I'm trained "enough" to head out into the world. Of course, Marsh is at the other end of his career. So fascinating how the same anxieties can flourish and grow in entirely different soil.

I want to read the book, but I wonder if now is the right time. Seriously! Might be better to wait a few years.

Only 38 more days to go until I complete residency.

Congratulations on finishing your training and becoming self-aware.

When I was a program director I used to laugh at residents who felt that they were so stressed. I would say to them, "If you think you're stressed now, wait until you're on your own and have to make a life-and-death decision in the middle of the night with no attending surgeon backup."

I haven't read Dr. Marsh's book, but the excerpts had an impact on me as well. I've been retired for 2½ years, and I still go over complications and mistakes in my mind. Even now, it is so real for me that sometimes I can't sleep.

CPR in space is possible, maybe

Last summer I wrote about the many problems associated with performing surgery in outer space. [Link here.]  Not surprisingly, I was highly skeptical about such issues as training astronauts to operate on each other and the difficulties in taking along enough supplies to deal with unexpected trauma and surgical diseases.

At least one commentor on that post felt that NASA had all the answers. But another said, “What NASA never wants to discuss publicly is the scenario: If X happens then you die.”

Not to be outdone, the European Space Agency recently released a YouTube video illustrating how cardiopulmonary resuscitation could be carried out in a weightless environment.

You can see that the technique is rather awkward and questionably effective. To my knowledge, the rescuer falling on the victim is not currently recommended in the latest CPR guidelines.

Assuming that by some miracle the victim survives CPR, what would happen to him? Would he be transferred to the intensive care unit on the spaceship? Would there be a ventilator? What about an endotracheal tube and someone to insert it? Who would monitor the patient? Would that person be subject to work hours limits?

Here’s what I think.

If you have a cardiac arrest on the way to Mars, you’re not only in deep space, you’re in deep doodoo.

Problem with my blog. I need your help

I have a big problem.

For the last 10 days, Twitter has been blocking me from tweeting any links to my blog.

This is the message I get whenever I try to send a tweet with "" in it.

I have tried to contact Twitter through @twitter and @support four times and have received no reply, nor have they replied to numerous ticket requests through the Twitter Help Center.

I discovered a site called which compiles reports from 63 different programs that detect viruses, worms, trojans, and malware.

Originally a site called BitDefender claimed my site was malicious. The next day, BitDefender declared my site was clean, but AutoShun, which previously had no problem with my site, said it was malicious. The following day, AutoShun said my site was unrated and Clean MX said "malicious." But the day after, AutoShun went back to calling it malicious and Clean MX said my blog was clean. At no time, did more than one of the 63 detection programs identify my blogsite is being malicious.

You would think that if my blog contained any suspicious programs, more than one of the 63 virus detection organizations would have come up with a positive result on the same day.

None of the programs saying my blog was malicious gave me any clue as to what part of my site was supposedly creating the problem.

I attempted to get some help from Blogger, which hosts my blog. Although one person on a forum responded with some advice, it wasn't enough for me to solve the problem.

My blog is averaging 1600 page views per day. Not one person has contacted me to complain that I am harboring viruses or any other malicious software. That is because, to the best of my knowledge, no such malicious software exists on my blog.

Maybe it would help if you would go to the results section of the virustotal website and cast your vote in favor of my site as not being malicious. In the upper right-hand corner of the site you will see this cartoon.

 Please click on the green face to support my blog.

Meanwhile, I have discovered an interesting workaround which enables me to tweet links to my blog, but visitors to the site will still be blocked by Twitter from tweeting links.

If you consider yourself computer-savvy, maybe you can figure out how I did it. If you think you know the answer, please submit a comment.

I also would welcome any comments or suggestions that could help to resolve my problem. If anyone knows a way to contact a human at Twitter, please let me know.

Problems with surgical residents and continuity of care

How are we doing with residency training and continuity of care? Not too well if you believe a recent paper called "Continuity of Care in General Surgery Resident Education" appearing online in the American Journal of Surgery.

A group from Rush University in Chicago looked at the records of 228 patients who underwent commonly performed operations during the year 2012. They found that in only 21/228 (9.2%) of cases had the operating resident seen the patient preoperatively, and in 20/223 (9.0%) had the operating resident seen the patient in postoperative follow-up. In no case, did the operating resident see the same patient both pre- and postoperatively.

The table lists the type of cases and the frequency of resident participation in preoperative care or postoperative follow-up.

This is important because on page 18 of the Residency Review Committee (RRC) for Surgery Program Requirements for Graduate Medical Education in General Surgery, the following is stated:

The robot is here to draw your blood

A company has produced prototype robots that can draw blood from human arms. Here is a 48 second video showing one of them in action.

Using an infrared camera, the robot identifies a suitable vein and accesses the vein with ultrasound guidance.

A second video, not embedded in this post, explains that the robot is about 83% successful at drawing blood which compares favorably to the success rate of experienced human phlebotomists. The robot's inventor hopes to refine the procedure to get the success rate up to 90%.

It also says that there are 9 billion blood draws per year in the United States suggesting that a market is certainly there.

The second video also mentions the discomfort patients experience when a phlebotomist misses or damages the vein.

Iatrogenic polyuria

Dr. William Reichert commented on a recent post of mine. I thought he told an interesting story and with his permission, I am featuring it here so more of you might see it.

He wrote

Some time ago, I was consulted on a patient because of excessive urination. The patent was putting out 4 or 5 five liters a day and nobody knew why. I checked out all the usual suspects, diabetic ketoacidosis, hyperglycemia, diabetes insipidus, etc. and all the medications listed on his chart. No diuretics. Finally, at my wit’s end, I entered the ICU room and noticed a number of med bags, some full, some empty hanging there on the IV pole. I checked each and discovered a bag labeled "dopamine” slowly dripping in.

I went to the nurse and asked how long the patient had been on dopamine. She said "He's not on dopamine." I said, "Come with me" and showed her that he was in fact getting low dose dopamine, a drug that behaves like a diuretic.
