CPR PRO® Device Reduces Rescuer Fatigue during CPR

CPR PRO
We have just published an article in The Journal of Emergency Medicine titled “CPR PRO® Device Reduces Rescuer Fatigue during Continuous Chest Compression Cardiopulmonary Resuscitation: A Randomized Crossover Trial Using a Manikin Model”

This is the first trial to test the benefits of the device I have invented and have been developing the last couple of years. This device is called CPR PRO and is intended to allow rescuers to performed better chest compressions.

Here is the summary of the article:

1. Why is this topic important?
Rescuers are often required to perform cardiopulmo- nary resuscitation (CPR) for prolonged periods of time, and their fatigue has been shown to cause significant decline in quality of chest compressions, which are crucial for survival of sudden cardiac arrest victims.

2. What does this study attempt to show?
In our randomized crossover trial, health care professionals performed continuous chest compression CPR for 10 min on a manikin to evaluate the impact of a novel CPR PRO! device for manual chest compression on res- cuer fatigue, pain, and CPR quality.

3. What are the key findings?
After using the CPR PRO device, subjects reported less pain in the hands and lower perceived exertion levels, as well as achieving lower average and maximal heart rates during testing, when compared to standard manual CPR. Reduced fatigue and pain has resulted in higher average depth of chest compressions, which declined more slowly over time, than with standard manual CPR.

4. How is patient care impacted?
In a simulated setting, a novel CPR PRO device for manual chest compression has been shown to reduce the work of CPR, which allowed rescuers to achieve signifi- cantly higher quality of chest compressions. Delivering higher quality of chest compressions with minimal interruptions in the clinical setting has a potential to result in better patient outcomes after sudden cardiac arrest.

mobile chain of survival
Just recently my colleague and I have published two research papers. I am very proud of the first one titled “Mobile phone in the Chain of Survival”, which was published after a lot of research in the Resuscitation journal. This short paper gives an overview of vast possibilities possessed by mobile phones to be of assistance in medical emergencies. It represents a continuation of my work with CPR mobile applications. I have also now published a video of the lecture I gave during the Resuscitation 2010 congress about the same subject. You can watch my 10 minute lecture here, and read our paper at the Resuscitation website.

The second paper we wrote appeared in the Croatian journal Lijecnicki Vjesnik (in English this would be something like Physician’s Newsletter). It is a case report demonstrating a patient with smell disorders, which we suspect were caused be lacidipine, a calcium channel blocker used to treat hypertension. So far this drug has not been linked with smell disorders, but other calcium channel blockers from the same group are well known to cause such problems. The paper is written in Croatian, but its abstracts is available in English – Can lacidipine cause smell disorders? A case report.

The Usefulness of Sonohysterography

By-line:
This article is contributed by Sarah Scrafford, who regularly writes on the topic of how to become a pharmacy technician. She invites your questions, comments and freelancing job inquiries at her email address.

A recent study conducted at the Thomas Jefferson University Hospital in Philadelphia has found that sonohysterography (SHG) is a highly effective transvaginal ultrasound technique that improves the ability of doctors to diagnose adenomyosis, a condition that causes severe pelvic pain combined with abnormal and unexplained vaginal bleeding.

SHG is a relatively new technique that allows medical practitioners to view a woman’s uterine cavity more clearly. A soft, plastic catheter is placed in the cervix in conjunction with transvaginal ultrasound, and a sterile saline infusion passed through this tube expands the uterus and also provides a contrast to the lining, thus giving doctors a better idea of what the problem really is.

  • Sonohysterography is especially useful in treating women with infertility – it helps determine the presence of polyps, fibroids or tumors that prevent conception.
  • Besides, it allows doctors to examine the uterine cavity before any surgery like a hysterectomy or a D&C procedure.
  • It also helps in investigating unexplained infertility and repeated miscarriages.
  • It’s a good diagnostic tool to explore unexplained vaginal bleeding in pre and post menopausal women.
  • It allows examination and assessment of the endometrium and reveals endometrial abnormalities.
  • A sonohysterography that’s performed before a suggested hysterectomy can sometimes help you avoid the hysterectomy altogether. So you’re saved the cost, mental stress, physical pain, and recovery from a surgery.

The main advantages of a sonohysterography are:

  • It’s painless and can be administered in a normal ultrasound scan room
  • It does not require the patient to be sedated or under the influence of anesthesia.
  • It is not as expensive as an MRI scan which is normally used to investigate abnormal bleeding
  • It is commonly available at most healthcare facilities.
  • It helps avoid invasive diagnostic procedures
  • It has no side effects and is not very uncomfortable for the patient
  • Diagnosis is quick
  • There are no complications to be worried about

Top 10 Most Read Medscape Articles by Medical Students

Medscape is a part of WebMD Health Professional Network and they offer specialists, primary care physicians, and other health professionals integrated medical information and educational tools. They also have a portal for medical students called Medscape Med Students, which I highly recommend.

For the end of this year they published a list of top 10 most read articles by medical students in 2008, and here they are. Free registration is required to read them.

  1. Surveying the Sex Lives of Medical Students
  2. A small study offers a glimpse of how medical school affects students’ sexual function. A larger survey may reveal a great deal more.

  3. How Should I Get Recommendation Letters for Residency?
  4. Asking faculty to write letters of recommendation for you can be a daunting — but doable — task.

  5. Making Students Cry (Or: How Hammering Home the Point Can Smash the Process to Pieces)
  6. A teacher can be so intent on correcting error, so focused on the point in hand, that they forget the person.

  7. A Puzzling Facial Rash on a 17-Year-Old Boy
  8. A 17-year-old boy presents to the pediatric infectious disease clinic with a 10-day history of a facial rash. No improvement was noted with 2 separate courses of antibiotic therapy. What is the most likely diagnosis?

  9. What Should I Bring on Overnight Call?
  10. This “Top 10” list could make your overnight shifts just a little more comfortable and productive.

  11. Woman With an Acute Onset of Nausea and Vomiting

Buy a video game console for your grandparents

video gamesThe research paper which will appear this month in the journal Psychology & Aging suggest you should buy your grandparents a video game console, or a PC loaded with games.

This study found that adults in their 60s and 70s can improve a number of cognitive functions by playing a strategic video games. “When you train somebody on a task they tend to improve in that task, whatever it is, but it usually doesn’t transfer much beyond that skill or beyond the particular situation in which they learned it,” he said. “And there are virtually no studies that examine whether there’s any transfer outside the lab to things people care about.”

After testing several video games, the researchers selected “Rise of Nations,” which gives gamers points for building cities and “wonders,” feeding and employing their people, maintaining an adequate military and expanding their territory.

The study included 40 older adults, half of whom received 23.5 hours of training in Rise of Nations. The others, a comparison group, received no training in the game.

Both groups were assessed before, during and after the video game training on a variety of tests designed to measure executive control functions. The tests included measures of their ability to switch between tasks, their short-term visual memory, their reasoning skills and their working memory, which is the ability to hold two or more pieces of information in memory and use the information as needed.

There were also tests of the subjects’ verbal recall, their ability to inhibit certain responses and their ability to identify an object that had been rotated to a greater or lesser degree from its original position.

The researchers found that training on the video game did improve the participants’ performance on a number of these tests. As a group, the gamers became significantly better – and faster – at switching between tasks as compared to the comparison group. Their working memory, as reflected in the tests, was also significantly improved. Their reasoning ability was enhanced. To a lesser extent, their short-term memory of visual cues was better than that of their peers, as was their ability to identify rotated objects.

The video game training had no effect on their ability to recall a list of words in order, their enumeration ability or their ability to inhibit certain responses, however.

There was a correlation between their performance on the game and their improvement on certain cognitive tests, Kramer said.

Those who did well in the game also improved the most on switching between tasks. They also tended to do better on tests of working memory.

“In medical terminology, these would be dose-response effects,” Kramer said. “The more drug – or in this case the more training on the video game – the more benefit.”
