Dual lumen catheters for angioaccess in patients with leukemia.
Dual lumen long-term indwelling right atrial catheters have been used to improve venous access in adult patients with leukemia. Twenty-eight such catheters have functioned for 1,895 days in 28 patients over the past eight months at the University of Maryland Hospital. Although insertion of the dual lumen catheter was more technically demanding than insertion of a single lumen catheter, the greater versatility in drug management (e.g., administration of two continuous infusions simultaneously or one continuous infusion leaving one line for platelets, blood, antibiotics or venous sampling) provided by the extra venous portal of entry more than compensated for any increased operative time (average, 58 vs 39 min/insertion). Eight episodes of bacteremia (0.37/100 patient days) occurred in these patients, but only one of these was associated with an exit site infection: the remainder were secondary to infections remote from the catheter. No catheter was removed as a result of these episodes, nor was any removed for ante mortem mechanical failure. The dual lumen catheter is a safe reliable device for providing angioaccess in patients with leukemia and offers substantially greater flexibility than the single lumen catheter.
