We evaluated the accuracy of a new disposable pump (Coopdech Syrinjector), which employed the negative pressure made by injecting fluid into the pump for continuous epidural infusion. Thoracic epidural catheter was placed at the T6-T8 level prior to the lung surgery. The continuous epidural infusion of 0.25% bupivacaine at 2 or 3 ml.h-1 was started immediately after the surgery. The residual volume of bupivacaine was recorded. From our results, the injection speed of Syrinjector was satisfactory for clinical use of continuous epidural infusion of bupivacaine. However, when this pump is reused or the volume of the residual local anesthetics is less than 10 ml, the infusion accuracy will be potentially imprecise.
