Conventional Chest Tube vs Pigtail Catheter

Leave a comment

Traditionally, hemothorax and pneumothorax in trauma has been treated with chest tubes. I’ve previously written about some of the debate regarding using smaller tubes or catheters. A paper that will be presented at the EAST meeting in January looked at pain and failure rates using 14Fr pigtail catheters vs 28Fr chest tubes.

This was a relatively small, prospective study, and only 40 of 74 eligible patients were actually enrolled over 20 months at a Level I trauma center in the US. Pain was measured using a standard Visual Analog Scale, as was complication and failure rate, tube duration and hospital stay.

The following interesting findings were noted:

  • Chest wall pain was similar. This is expected because the underlying cause of the pneumothorax, most likely rib fractures, is unchanged.
  • Tube site pain was significantly less with the pigtail
  • The failure rate was the same (5-10%)
  • Complication rate was also the same (10%)
  • Time that the tube was in, and hospital stay was the same

Bottom line: There may be some benefit in terms of tube site pain when using a smaller catheter instead of a chest tube. But remember, this is a very small study, so be prepared for different results if you try it for your own trauma program. If you do choose to use a smaller tube or catheter, remember to do so only in patients with a pure pneumothorax. Clotted blood from a hemothorax will not be completely evacuated.

EAST 2017 #7: Pigtail vs Chest Tube – Does Size Matter?

Leave a comment

I’ve been somewhat old school when it comes to chest tubes. Unlike some, I don’t believe that you have any control of where a chest tube goes if you are placing it in a closed chest. Only in the OR with an open one. And I’ve got plenty of x-rays to prove it.

And I used to think that chest tube size mattered when dealing with hemothorax. In theory, you need a big tube to get clots out, right?

Well, maybe not! The trauma group at the University of Arizona Tucson has previously done work on using 14 French pigtail catheters in lieu of a full-size tube. They will be presenting their extended experience with this concept at EAST 2017.

They have maintained a prospectively collected database of information on trauma patients with chest tubes for many years. This study focused only on those who had blood in their chest, either hemothorax (HTX) or hemopneumothorax (HPTX). They also looked at trends in their selection of chest drain tubes.

Here are the factoids:

  • Nearly 500 patients were treated with a tube for HTX or HPTX during the 7 year study period, 2/3 with a chest tube and 1/3 with a pigtail
  • Pigtails had more fluid drain initially (430cc vs 300cc, significant), and 1 less treatment day (4 vs 5, also significant)
  • Failure rate and insertion-related complications were the same (about 22% and 6%, respectively)
  • The group found that their use of pigtails steadily and significantly increased over the years

Bottom line: I’m coming around. The literature does appear to be tilting toward smaller tubes, and this longer-term study helps confirm that. How can this be? Although this is speculation on my part, it probably has to do with the fact that any size tube will drain liquid blood. And probably no size of tube will successfully get all the clot out. 

And certainly, smaller tubes are much better tolerated and do not require the degree of sedation that a mega-tube does. The authors suggest that a multi-center trial should be carried out to confirm this. For my part, I’m going to review the literature we have to date and consider modifying my own chest tube policy (see links below).

Questions and comments for the authors/presenters:

  • Where did you typically insert the pigtails? Anterior chest or classic chest tube position? Was it consistent?
  • Was/is the selection of tube type an attending surgeon specific choice, or did you implement a policy to direct them?
  • Did patient injury pattern or body habitus have any part in tube selection?
  • What about removal failures? That is, how many had to have a tube replaced, and how many went on to require VATS or other surgical procedure for drainage?
  • I enjoyed this provocative paper!

How To: Insert A Small Percutaneous Chest Tube

Video Leave a comment

This short (10 minute) video demonstrated the technique for inserting small chest tubes, also known as “pigtail catheters.” It features Jessie Nelson MD from the Regions Hospital Department of Emergency Medicine. It was first shown at the third annual Trauma Education: The Next Education conference in September 2015, for which she was a course director.

Pigtail Cathers Instead Of Chest Tubes?

Leave a comment

I reviewed this abstract a few months ago, and now I’ve had the opportunity to hear it and see the data. Here’s an update on whether this is worthwhile..

This was a relatively small, prospective study, and only 40 of 74 eligible patients were actually enrolled over 20 months at a Level I trauma center in the US. Pain was measured using a standard Visual Analog Scale, as was complication and failure rate, tube duration and hospital stay.

The following interesting findings were noted:

  • Chest wall pain was similar. This is expected because the underlying cause of the pneumothorax, most likely rib fractures, is unchanged.
  • Tube site pain was significantly less with the pigtail
  • The failure rate was the same (5-10%)
  • Complication rate was also the same (10%)
  • Time that the tube was in, and hospital stay was the same

There were a few questions regarding blinding of the pain scale raters, but other than the small sample size, the study was nicely done.

Bottom line: There may be some benefit in terms of tube site pain when using a smaller catheter instead of a chest tube. But remember, this is a very small study, so be prepared for different results if you try it for your own trauma program. If you do choose to use a smaller tube or catheter, remember to do so only in patients with a pure pneumothorax. Clotted blood from a hemothorax will not be completely evacuated.
