Pigtail Cathers Instead Of Chest Tubes?

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.
