Ultrasound-guided Central Line Placement: Embed Several Videos in One Frame


Video: Ultrasound-guided Central Line Placement

Google Docs is a free web-based word processor, spreadsheet, and presentation application.

You can include YouTube videos, images, and text captions into slides to condense and display a “deck” of graphical content in a concise format in your posts.

For example, instead of publishing several videos on one page, you can insert videos and pictures in an embedded presentation slideshow -- see the example above.

I picked the topic of Ultrasound-guided Central Line Placement because this modality is of proven efficacy and safety but is still underutilized. A colleague of mine and I published a A Step-by-Step Procedure Guide with Photos for Central Line Placement with Ultrasound Guidance in an attempt to popularize the approach. A free PDA version of this procedure guide is available from MeisterMed.

What to do if you lose a guide wire during central line placement?

I was discussing central line placement complications with medical students a few days ago. Some of them are illustrated with horrifying details in the NEJM.

"What should you do if you lose a guide wire during central line placement?", I asked.

"We could use a strong magnet to pull it out", one of the students suggested.

Well, not really.

You should call interventional radiology immediately and the radiologist will extract the wire under fluoroscopic guidance by using another wire to hook up and pull out the lost one.

A few examples of different approaches to extract lost guide wires are listed in the British Journal of Anaesthesia.

We have published free illustrated step-by-step procedure guides to central placement with and without ultrasound. The guides are available as web pages and Windows Mobile/Palm downloads.

Free Procedure Guides for Pocket PC/Windows Mobile and Palm

Two years ago, a colleague of mine and I made several procedure guides illustrating central line placement and thoracentesis with step-by-step photos:

Central Line Placement - A Procedure Guide

Central Line Placement with Ultrasound Guidance - A Procedure Guide

Thoracentesis - A Procedure Guide

These photo guides proved very popular and are currently used for teaching purposes by residents at Cleveland Clinic and Case Western Reserve University/St. Vincent, and are linked in Wikipedia among several other web sites.

Eight months ago, I got an email from Andrew Schechtman, a Clinical Instructor at Stanford University School of Medicine and the founder of MeisterMed, a popular PDA portal for medical references. Andrew wanted to know if I was interested in adapting the procedure photo guides to PDA and distributing them for free. The original idea behind the guides was that they should be free and used by residents and physicians all over the world, and his suggestion to adapt them for PDA fitted that idea perfectly. I thought about it but somehow never found the time to do it.

Anyway, the procedure guides for PDA are now available for free from MeisterMed:

The guides themselves are free but they need the iSilo program for Pocket PC/Windows Mobile or Palm to work. The full version of iSilo is required to see the images beyond the trial period and that version costs $ 19. The guides are just like Microsoft Word documents -- you need to have MS Word installed on your computer in order to see the documents. Similarly, you need iSillo installed on your PDA to be able to see the photo guides.

Procedure guides are part of the MeisterMed Procedure Series which will be adding more titles in the near future.

Central Line Placement Videos on YouTube

The videos below show "practical tips and tricks for central line placement in the ED." ClinicalCases.org has our own step-by-step procedure guides with photos:

Central Line Placement - Procedure Guide

Central Line Placement with Ultrasound Guidance - Procedure Guide

Without a doubt, videos are better than still photos in many ways. Photos have the advantage of being able to see clearly what is going on though. It is similar to comparing Flickr to YouTube (or Google Video) -- both are needed for a complete visual experience.

Clinical Procedure Guides on Picasa Web: Step-By-Step Photos

I have just moved the three procedures guides we created to Picasa Web Albums:

Central Line Placement - Procedure Guide

Central Line Placement with Ultrasound Guidance - Procedure Guide

Thoracentesis - Procedure Guide

Picasa Web works great: it resizes the images automatically to fit the monitor size and pre-fetches them so that the slideshows load faster. Our previous host, Webshots, used to place too many banner ads around the images but I chose it over Flick because it offered a larger resolution of the slideshows.

Andrew Schechtman of MeisterMed contacted me last week with the suggestion to create a free PDA guide for clinical procedures. I hope that this project is completed soon.

Of course, our slideshows cannot compete with the excellent professional NEJM videos but this is not the goal. The idea is to help any health care worker anywhere in the world by offering a quick reference guide to refresh the memory about a certain procedure before performing it. In our informal surveys, many residents at the Cleveland Clinic and Case Western/St. Vincent find the guides very helpful.

Unfortunately, NEJM recently removed their procedures videos from the free area of the website and started to charge $ 10 per video.

Is Physical Examination Useless?

There has been a lot of discussion in the medical blogs recently about the usefulness (or lack) of physical examination.

I personally think that physical exam is very important but when "the HMOs force physicians to care for a maximum number of patients, in a minimum number of minutes for the lowest number of dollars" something has to give...

One of the comments on KevinMD says that clearly: "Why do I have the feeling this guy never had to see 40 patients a day at 15-minutes per encounter... I bet his physical exams would leave a lot to be desired at that rate."

Anyway, if you want to refresh your skills, you can review this large collection of free physical examination videos organized by body system.

Update 3/23/2007:

Dr. Wes comments on "Procedural Darwinism":

Take the stethoscope, for instance. It is rapidly succumbing to Procedural Darwinism. If it weren’t for the stethoscopes ability to hear breath sounds, it would have been extinct long ago. The echocardiogram is far superior to “hear” heart sounds, and adds procedural survival protection by providing additional size, structure, and functional information regarding the heart with little pain or toxicity to the patient. The echo also reimburses well.

How to confirm a nasogastric tube (NGT) placement? By CXR or KUB?

Case scenario:

A 65-year-old Caucasian female (CF) has a new-onset dysphagia secondary to stroke. The speech therapist did a swallow evaluation and found out that the patient is at high risk for aspiration even with soft mechanical diet and honey-thick liquids. She recommended placing a fine-bore feeding tube, Isocal HN with a goal of 90 ml/hr and a repeat swallow evaluation in 3-4 days.

The patient understands and agrees. You have just placed a Corpak tube and tested its postion by pushing 30 cc of air through the tube.

How to confirm the nasogastric tube (NGT) placement? By CXR or KUB?

NGT placement is confirmed by CXR. It is important to see that the NGT is below the diaphragm. One JAMA report concluded that the traditional physical examination-based methods of assessing proper NGT placement are inadequate when applied to the small-bore tubes (for example, Corpak). Only a CXR can assure placement in the stomach.

Why not KUB? What are the complications of NGT placement?

Most of the important complications of NGT placement are related to penetrating the esophagus or passing the tube in the trachea and bronchi. Occasionally, an NGT can penetrate the brain. These misplacements will not be shown on the abdominal x-ray (KUB) and the consequences can be deadly:

In 2000, a 78 year old patient died after she was fed through an NGT which was wrongly placed. The prosecutor case was that the junior doctor had been asked by nurses to look at an x-ray that would have shown that the tube was protruding into a lung and had given the go ahead for feeding to start. When the patient was fed, the food passed into her lung, and she died from acute pneumonia (Source: BMJ 2003).

Examples of NGT misplacement:


NGT in right main bronchus. Report of KUB/Abdomen - portable: A Corpak feeding tube is in place with the tip extending into the right mainstem bronchus. The staff was aware and the feeding tube had been pulled. There is no bowel obstruction.

This X-ray clearly shows why NGT placement should be confirmed with CXR. KUB almost missed the NGT tip.


NGT is too high, in the esophagus and above the diaphragm, not in the stomach. This placement is associated with high risk for aspiration. The NGT must be advanced further down and the new placement should be confirmed with a CXR.

Some important things to remember:



- Measure the expected lenght to reach the stomach (the suggested method is shown here, image source: CPEM.org)
- Sit the patient upright, if possible
- Flex the neck a little. This is just the opposite of the neck extension which is essential for tracheal intubation. In NGT placement you want to avoid the tracheal intubation. This is the reason for flexing the neck.
- Never force the NGT, it should go down smoothly. Ask the patient to swallow.
- Read more about the procedure in the references listed below

If you are not sucessful in placing an NGT on the first attempt, do not despair. Ask somebody (a senior colleague) to help you. Even Dr. Genes, the founder of the online Grand Rounds, had trouble passing a NGT as an intern.

Medical Students Practice Procedures on Robots

The robot is breathing and reacts when you perform procedures. There is a blood-like liquid when you attempt a venipuncture. You can see the results of your heroic CPR actions in real time. No, this is not science fiction but a regular practice session at the Autonomus University's school of medicine in Mexico City, which is the largest in Latin America.

There are 24 robotic patients and a computer program that simulates illnesses ranging from diabetes to a heart attack.

One of the medical students admits every new student's fear: "I would feel nervous if this was a real patient. With this I can practice many times."

The story was reported by AP, Reuters and ABC but I like the Medgadget coverage the best. The guys who keep that blog running are doing a good job - today I was searching for a new type of wound treatment, called EpiFLO, and Medgadget was the number two hit on Google.

Medgadget links to the Mexico City's UNAM University web page (translated to English with Google). We use the same translation tool on this blog.

The Case School of Medicine is working on a Medical Simulation Lab (pdf). The team has a blog on blog.case.edu.
