Pigtail Catheters Instead Of Chest Tubes?

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.

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%)

(5-10%) Complication rate was also the same (10%)

(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.
