Trimming long-term tunneled central venous catheters: Scalpel produces a smoother surface compared to scissors


Intravenous literature: Inserra, A., Crocoli, A., Conforti, A., De Petris, L. and Jenkner, A. (2012) Trimming long-term tunneled central venous catheters in pediatric patients. Pediatric Blood & Cancer. Sep 19. .


Long-term tunneled central venous catheters (CVC) are employed in critically ill patients. Manufacturers do not provide patient-customized devices; therefore, trimming is required for pediatric use. Scanning Electron Microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy and attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR) was used to assess changes induced by different trimming methods on single and double lumen Hickman-Broviac catheters. Increased roughness, exposure of inorganic macroaggreagates and increase in surface inorganic charges were generated by the trimming procedure, with the scalpel producing a smoother surface compared to scissors. Trimming produces changes on the CVC surface that may influence the rate of long-term complications.
