PLEASE NOTE: Mixing of these solutions has not been tested and is not recommended.
Is the MAHURKAR™* 12Fr. triple lumen catheter available in a curved configuration? The MAHURKAR™* 12Fr. triple lumen catheter is available in both curved and straight extensions.
Can the MAHURKAR™* 12Fr. triple lumen catheter be placed in the femoral vein or from a left-sided approach? Yes. The MAHURKAR™* 12Fr. triple lumen catheter contains a strain relief at the catheter shaft/hub connection. It provides a secure transition of the catheter shaft and hub. The hub material extends further down the catheter shaft preventing kinking of the catheter during insertion and use at the hub/catheter connection site.
Why would I use a triple lumen acute catheter instead of a standard dual lumen acute catheter? This depends on the physician and the patient. The triple lumen catheter will best serve those situations where preservation of vascular access is a key factor. The third infusion port is a dedicated line that is completely independent from the two (2) larger dialysis lumens. It can be used like a standard central line for blood access and fluid or medication delivery between dialysis treatments without the need for a separate access. The MAHURKAR™* 12Fr. triple lumen catheter was designed with the need for additional access in mind.
What is different about the insertion of a triple lumen acute catheter vs. that of a standard dual lumen acute catheter? There is no difference. Both catheters will be inserted using a percutaneous approach, the seldinger technique.
Does the flow rate of the MAHURKAR™* 12Fr. triple lumen catheter differ between straight extensions vs. curved extensions? Studies conducted with the MAHURKAR™* 12Fr. triple lumen catheter indicate that there is no significant difference between the flow rates of the straight and curved extension versions.
Can the MAHURKAR™* 12Fr. triple lumen catheter be exchanged over a guidewire? If you currently exchange acute catheters over a guidewire, the MAHURKAR™* 12Fr. triple lumen catheter can also be exchanged over a guidewire. You should always follow your facility's existing protocol. A full explanation for catheter exchange is detailed in the product's instructions for use (IFU).
What gauge size is the third infusion lumen on the MAHURKAR™* 12Fr. triple lumen catheter? The third infusion lumen on the MAHURKAR™* 12Fr. triple lumen catheter is 19 gauge.
What gauge size are the larger dialysis lumens on the MAHURKAR™* 12Fr. triple lumen catheter? The larger dialysis lumens on the MAHURKAR™* 12Fr. triple lumen catheter are 15 gauge.
What is recommended to maintain patency of the MAHURKAR™* 12Fr. triple lumen catheter between dialysis or apheresis treatments? To maintain patency between dialysis or apheresis treatments, keep the lumina of the catheter filled with the appropriate concentration and volume of heparin. In most cases, 5000 Units/cc is cost successful (refer to priming volumes of catheter). Approved heparin concentrations vary within each institution. The medial infusion port may be treated as a standard central line as per hospital protocol. Be sure to use those heparin concentrations approved by your facility.
What is recommended for exit site care with the MAHURKAR™* 12Fr. triple lumen catheter? Catheter care must be performed at least every three (3) days or as specified by the institution; more frequently if the dressing should become wet or soiled. Use sterile technique when handling or using the catheter.
How long can a MAHURKAR™* 12Fr. triple lumen catheter be left in place? According to the National Kidney Foundation, Kidney Dialysis Outcome Quality Initiatives (NKF, K-DOQI), non-cuffed, double-lumen catheters may be used for up to three (3) weeks. Due to infection and dislodgement rates, femoral catheters require that they be left in place no more than three (3) to four (4) days and only in bed-bound patients with good exit site care.
How long should a femoral catheter be to ensure optimal performance with the MAHURKAR™* 12Fr. triple lumen catheter? According to the National Kidney Foundation, Kidney Dialysis Outcome Quality Initiatives (NKF, K-DOQI), to minimize recirculation femoral catheters should be at least 19cm long to reach the inferior vena cava and optimize performance.
Where should the tip of a jugular catheter be located to optimize performance of the MAHURKAR™* 12Fr. triple lumen catheter? According to the National Kidney Foundation, Kidney Dialysis Outcome Quality Initiatives (NKF, K-DOQI), jugular catheters require chest x-ray or fluoroscopy to confirm catheter tip position at the caval atrial junction for optimal performance.
Are there any risks to subclavian vein insertions with the MAHURKAR™* 12Fr. triple lumen catheter? According to the National Kidney Foundation, Kidney Dialysis Outcome Quality Initiatives (NKF, K-DOQI), subclavian insertion should not be used in patients who may need permanent vascular access. A catheter insertion in the subclavian vein may result in subclavian vein stenosis, which may impair use of the ipsilateral extremity for future vascular access. Subclavian access also requires chest x-ray or fluoroscopy to confirm catheter tip position at the caval atrial junction.
What clinical support do you have that the MAHURKAR™* 12Fr. triple lumen catheter does not increase the risk for infection or decrease flow rates when compared to a standard dual lumen acute dialysis catheter? Contreras et. al., published a prospective, randomized, multi-center study in 485 patients in the American Journal of Kidney Disease, 42(2): 315-324, 2003. This study compared the MAHURKAR™* 12Fr. triple lumen catheter to a standard dual lumen acute dialysis catheter. The results showed no difference in flow performance between the MAHURKAR™* 12Fr. triple lumen and dual lumen catheters and physicians achieved the desired flow rates that they prescribed 100% of the time. They also found that even though the MAHURKAR™* 12Fr. triple lumen catheters were handled and utilized more often than the dual lumen catheters, this did not lead to a higher incidence of catheter related blood stream infections.
