Comparative StudyThe effect of fluid injection on lesion size during radiofrequency treatment.
Previous ex vivo studies on monopolar radiofrequency have not incorporated the preinjection of fluid before radiofrequency ablation into study design. The objective of this study was to investigate the effects of the preinjection of small volumes of different fluids on lesion dimensions. ⋯ The influence of the composition of the pre-injected fluid should be considered for monopolar radiofrequency ablation. This ex vivo study revealed a simple method to increase monopolar radiofrequency lesion size. Future research is needed to determine the degree of influence of the composition of the fluid on thermal and electrical conductivity.
