Abstract
A Sodium Bicarbonate Catheter Lock Solution that prevents clot formation inside the catheter lumen and ensures patency of the catheter and also eliminates bleeding and other complications caused through the use of anticoagulants and other solutions as a catheter locking solution. Said lock solution may be used with or without other components such as antimicrobials/antibiotics and/or anti-coagulants/anti-clotting agents.
Claims3
A method of preventing catheter occlusion or thrombosis in a catheter during dwell time, consisting of the steps of:
- providing a patient with a central catheter for vascular access;
- and
- inserting into a lumen of said catheter a stand-alone anti-clotting lock solution consisting of 8.4% of sodium bicarbonate “and an antimicrobial agent” to mitigate clotting within said lock solution in order to keep patency when said catheter is not being used for treatment of a patient.
