We have experienced a leakage of infusing fluid at the site of infusion filter ELD-096 LL(PALL) when used in combination with a syringe pump and the insertioncatheter "L-cath". So we measured of obstruction alarm thresholds in two kinds of syringe pumps.With 20 ml syringe, the obstruction alarm threshold of STC-525 (TERUMO) was 2 Kg/cm^2 which was the pressure resistance limit of the infusion filter ELD-096 LL. The threshold was 1 Kg/cm^2 when STC-525 was used with a 50 ml syringe. The thresholds and 1235 (ATOM) was 1 Kg/cm^2 when used either with a 20 ml or 50 ml syringe.The time which need to start operation of the obstruction alarm became longer with slower infusion rate. It took about 2 hours to start when used with the rate of 1 ml/h and even longer with the infusion filter.We must be careful in using syringe pumps and take these characteristics intoconsideration.
