Continuous Flush System for Radial Artery Cannulation

Abstract

A prospective study of 50 radial artery cannulations was carried out using the I ntraflo conttnuous flushing device. Fl£nctional patency was maintained in all cannulations. No serious complications were seen. It is concluded that this method of continuous flushing is preferable to intermittent mam£al flushing.

Flush volumes delivered from pressurized bag pump flush systems in neonates and small children

“…Keywords: anaesthesia: neonatal, arterial pressure monitoring; equipment: arterial catheters, flush systems, pressure bag Introduction Arterial vascular catheters for invasive blood pressure monitoring and for intermittent diagnostic blood sampling are usually flushed with a heparinized solution to minimize or prevent occlusion of the cannula (1). Pressurized infusion bags, as routinely used at 300 mmHg manometer pressure combined with a standard flow regulating device, provide continuous flushing of the cannula at a flow rate of approximately 3 mlAEh )1 (2)(3)(4)(5). During fast bolus flushing while opening the flow regulating device, flow rates of 0.5-5.7 mlAEs )1 have been reported with bag pump flush systems (6,7).…”

A Comparison of Continuous Flush Devices

“…6 ,7 Although there are now many different devices commercially available, few have been subject to independent assessment. 7 Rithalia and Tinker evaluated six makes of flush devices in 1982.8 However, they did not specify that full 500 ml bags were used in their infusion systems. Moreover they only monitored infusor cuff pressure and not delivered pressure.…”
