Abstract
Introduction Insulin adsorption onto infusion equipment may affect glycaemic control. Methods The change in insulin concentration during delivery through tubing employed for adult ICU and neonatal patients was determined using continuous flow UV analysis. Results Insulin adsorption depended on tubing composition, dimensions and flow rate, being highest for neonatal polyvinylchloride tubing at low flow rates. Conclusion In continuous insulin therapy, we should consider the nature of the infusion set and flow rate.
