Infusion pump dose error reduction systems: trends in purchasing and use.

View original source ↗Export metadata ↓

Abstract

Over the last three years, infusion pump suppliers have begun introducing dose error reduction systems. The primary function of these systems is to reduce pump programming errors and associated injuries to patients. However, these systems can offer other benefits as well. In this article, we describe ways that hospitals can use dose error reduction system data to improve patient care and staff efficiency. We also detail the fees that accompany this new software and discuss the potential for increasing patient safety using wireless capabilities.

Do antisiphon valves reduce flow irregularities during vertical displacement of infusion pump systems?

Vertical displacement of syringe pumps may cause irregular drug delivery due to hydrostatic pressure changes in the infusion line. The extent of flow fluctuations depends on the internal compliance of infusion lines, syringes and syringe pumps. We evaluated whether pressure regulation by antisiphon valves (ASV) reduces the flow variation during vertical displacement of 50 ml standard syringes and infusion pumps. An infusion assembly comprising a standard 50 ml BD Plastipak or a 50 ml Fresenius syringe, with syringe pump and 2 m low compliance infusion line was used for in vitro measurement of fluid delivery. The assembly was tested without ASV, and with two ASVs of differing operating pressure (ASV:75: valve opening pressure = 75 mmHg; ASV:155, 155 mmHg). Retrograde aspiration volume, zero-drug delivery time and valve opening bolus were determined after lowering the syringe pump by 50 cm. After elevating the syringe pump to its initial position the ensuing infusion bolus was recorded. Without an antisiphon valve the observed zero-drug delivery times after lowering the syringe pump were (mean +/- SD) 2.4 +/- 0.2 min using the BD Plastipak syringe and 4.09 +/- 0.55 min using the Fresenius syringe. Introduction of the antisiphon valve prolonged the zero drug delivery time 58% (ASV:75) and 88% (ASV:155) in the BD Plastipak syringe assembly and 43% (ASV:75) and 81% (ASV:155) in the Fresenius syringe assembly (P < 0.001). Antisiphon valves worsen flow irregularities caused by vertical displacement of syringe pumps and when used with delivery of concentrated inotropic drugs at low infusion rates, they may aggravate haemodynamic consequences of inconstant drug delivery.
