Double Lumen Catheter
What is an Double Lumen Catheter?
How Double Lumen Catheter work
For the treatment of ARF in the ICU, double-lumen catheters are used instead of single-lumen catheters. The latter requires a dialysis machine able to deliver dialysis using the mode “single needle” but is associated with higher recirculation, decreasing the delivered dialysis dose. The best insertion site providing the higher blood flow is the right jugular vein, but femoral access still remains the emergency site and is associated with the lower rate of acute complication during insertion. Concerning the rate of nosocomial infection or catheter dysfunction between jugular and femoral access, recent data seem to challenge the usually reported higher rate of infection or catheter dysfunction with femoral access.9,10 The subclavian access should be avoided, considering the high rate of venous stenosis after dialysis catheter insertion.
Usually the use of an arteriovenous fistula in chronic renal failure patients is discouraged in the ICU, considering the risk of infection, the risk of low cardiac output, and the lack of experience of the ICU nurse. Use of the long-term cuffed catheter may be considered after the acute phase in a stable patient, but the occurrence of systemic infection usually leads to catheter removal. The diameter of the catheter is important to consider to obtain a good blood flow with acceptable pressures. In this setting, 12 Fr seems to be the minimal inner diameter.
How Double Lumen Catheter procedure is performed
The catheter is laid across the chest along the path of the guide wire and is positioned to curve gently down over the anterior chest. The exit site of the catheter is chosen 3 cm distal to the Dacron cuff and is in- filtrated with 1% lidocaine. The skin and subcuta- neous tissue along the planned catheter track are also infiltrated with 1% lidocaine. A i cm incision is made at the selected distal exit site and at the proximal guide wire exit site. A clamp is passed between the two incisions and the catheter is grasped and posi- tioned in the track so that the Dacron cuff is 3 cm from the skin exit site.
