ABSTRACT
PURPOSE:
To compare the performance of a dual-lumen flushable drainage catheter to a conventional catheter for complex fluid collection drainage.METHODS:
Two prototype catheters (20- and 28-F) were created by incorporating a customized infusion lumen within the wall of a large-bore conventional drainage catheter, which facilitated simultaneous irrigation of the drainage lumen and the targeted collection via inward- and outward-facing infusion side holes. These were tested against unaltered 20- and 28-F conventional catheters to determine if the injection of a dedicated flush lumen improved rapidity and completeness of gravity drainage. In vitro models were created to simulate serous fluid, purulent/exudative fluid, particulate debris, and acute hematoma.RESULTS:
In the purulent model, mean drainage rate was 19.9 ± 8.0 and 9.5±1.4 mL/min for the 20-F prototype and control (P < .001) and 63.9 ± 4.3 and 35.4 ± 3.4 mL/min for the 28-F prototype and control (P = .006), respectively, with complete drainage achieved in all trials. In the particulate model, mean drainage rate was 24.5 ± 9.7 and 12.0 ± 12.5 mL/min for the 28-F prototype and control (P = .003), respectively, with 69.0% versus 41.1% total drainage achieved over 24 minutes (P = .029). In the hematoma model, mean drainage rate was 22.7 ± 4.6 and 4.8 ± 4.3 mL/min for the 28-F prototype and control (P = .022), respectively, with 80.3% versus 20.1% drainage achieved over 15 minutes (P = .003). Particulate and hematoma 20-F prototypes and conventional trials failed due to immediate occlusion.CONCLUSIONS:
The proposed dual-lumen drainage catheter with irrigation of a dedicated flush lumen improved evacuation of complex fluid collections in vitro.
