Chest Tube Versus Pigtail Catheter Drainage of On-Going Hemothorax in Swine (Sus scrofa)
Abstract
Background: We compared pigtail catheters with chest tubes for the drainage of acute HTx in a swine model. Methods: Six Yorkshire-cross swine were anesthetized, instrumented, and mechanically ventilated. A 32F chest tube was placed in one randomly assigned hemothorax; a 14F pigtail catheter was placed in the other. Each was connected to a chest drainage system at -20 cm H2O suction and clamped. Seven hundred-fifty milliliters of the withdrawn blood was instilled into each pleural space, and fluid resuscitation with colloid was initiated. 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 +/- 109 mL/min vs. 176 +/- 53 mL/min) but this difference was not statistically significant (p=0.19). 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 was not statistically significant (p=0.21). Conclusion: We found no statistically significant difference in the volume of blood drained by a 14F pigtail catheter compared to a 32F chest tube.
