MP56-07 EFFECT OF 6F DUAL LUMEN CATHETER ON FLOW RATE DURING VIDEO-URODYNAMIC INVESTIGATIONS

Recirculation is an important factor in single needle dialysis and, if high, can compromise treatment efficiency. To provide information regarding recirculation characteristics of access devices used in single needle dialysis, we have developed a new technique to characterise recirculation and have used this to measure the recirculation of a Terumo 15G fistula needle and a VasCath SC2300 single lumen catheter. The experimentally obtained results agreed well with those established clinically (8.5 ± 2.4% and 18.4 ± 3.4%). The experimental results have also demonstrated a dependence on access type, pump speeds and fistula flow rate. A comparison of experimental data with theoretical predictions showed that the latter exceeded those measured with the largest contribution being due to the experimental fistula.

The objective of this study was to determine if a peripheral dual-lumen catheter could be used for accurate tobramycin blood concentration measurement when drug administration and blood sampling were undertaken through separate lumens of the catheter. Eleven adult volunteers received tobramycin 1.5 mg/kg iv infused over 30 minutes through the distal lumen of the dual-lumen catheter every eight hours for two doses. Multiple blood samples were obtained concurrently from the proximal lumen of the catheter and a single-lumen catheter in the contralateral arm after each dose. Blood samples were also obtained through the distal lumen before and 30 minutes after the end of the infusion. Accurate blood samples were obtainable through the dual-lumen catheter in only 5 of 11 subjects due to either infiltration or difficulties in catheter placement. In the subjects from whom accurate blood samples were obtained, approximately 20 minutes postinfusion was the amount of time required before measured tobramycin serum concentrations were similar between the arm in which the drug was infused (site of the dual-lumen catheter) and the contralateral arm. At standard times for obtainment of trough (just prior to the infusion) and peak (30 minutes after the end of a 30-minute infusion) tobramycin serum concentrations from the proximal lumen of the dual-lumen catheter were numerically similar to those obtained from the contralateral arm. This preliminary study indicates that the dual-lumen catheter provides accurate aminoglycoside concentrations when patent relative to blood withdrawal and if peak blood samples are obtained at least 30 minutes postinfusion through the recommended lumen. However, further study in a larger number of subjects is required before routine use of this device can be recommended.

Objectives: The purpose of this study was to compare the newly designed dual-lumen venovenous catheter (VR13, OriGen Biomedical, Austin, TX) with the current dual-lumen catheter (VV12, OriGen Biomedical). Methods: Five newborn lambs, 1 to 5 days old and weighing 4.2 ± 0.5 kg, were cannulated with the VV13 OriGen catheter and placed on extracorporeal membrane oxygenation (ECMO). ECMO flows were increased from 200 to 600 ml/min, with measurements taken after the changes. The experiment was then repeated using the VV12 catheter. Results: Recirculation values were equal for both catheters. The pressure drop at the reinfusion port was equal for both catheters at 200 ml/min, increasing to 275 mmHg at 500 ml/min for the VR13 vs. 240 mmHg for the VV12 catheter. Conclusion: These findings indicate that the VR13 catheter resulted in levels of recirculation equal to the VV12. Based on resistance measurements, we do not recommend the use of this new catheter beyond 400 ml/min until minor design changes are made.
