Abstract:

Background Management of traumatic hemothorax HTx with pigtail catheters has not been widely adopted due to concerns about blood evacuation rates. We compared pigtail catheters with standard chest tubes for the drainage of acute HTx in a swine model. Methods Seven hundred-fifty milliliters of blood was withdrawn from each femoral artery and instilled into each pleural space in mechanically ventilated swine. A 32F chest tube was placed in one randomly assigned hemothorax a 14 F pigtail catheter was placed in the other. Output from each drain was measured every minute for 5 minutes, then every 5 minutes for 40 minutes. Results Blood drainage was more rapid from the chest tube during the first three minutes compared to the pigtail catheter 348 I 09 mLmin vs. 17653 mLmin but this difference was not statistically significant p0.19. Thereafter, the rates of drainage between the two tubes were not substantially different. The chest tube drained a higher total percentage of the blood from the chest 87.3 vs 70.3 , but this difference did not reach statistical significance p0.21 . Conclusion We found no statistically significant difference in the volume of blood drained by a 14F pigtail catheter compared to a 32F chest tube.
