| Abstract | BACKGROUND: We compared Nexfin non-invasive arterial pressure measurements using a novel small finger cuff with intra-arterial pressure in the paediatric setting in order to establish the level of agreement between both methods. METHODS: The study included 41 children aged 2-16 yr admitted for surgery or paediatric intensive care with an intra-arterial catheter as part of standard monitoring. Values of systolic (SAP), diastolic (DAP), and mean arterial pressure (MAP) were obtained simultaneously from the intra-arterial catheter and the non-invasive Nexfin monitor. Data were analysed using intra-class correlation (ICC) coefficients and the Bland-Altman analysis. RESULTS: A non-invasive arterial pressure signal was obtained in the majority of patients. The reproducibility of arterial pressure measurements over time by both non-invasive and invasive techniques was high, with ICC coefficients ranging from 0.94 to 0.98. The Bland-Altman analysis for SAP, DAP, and MAP revealed a bias with 95% limits of agreement of -13.5 (-39.7; +12.8), -0.2 (-12.8; +13.2), and -2.6 (-17.7; +12.5) mm Hg, respectively. Linear regression suggested a weak correlation of SAP and the bias between intra-arterial and Nexfin SAP measurements (intercept 4.9 mm Hg, ß -0.29; P=0.01). CONCLUSIONS: Nexfin non-invasive arterial pressure measurements are feasible in paediatric patients. Nexfin accurately reflects the intra-arterial MAP and DAP curves, but seems to underestimate SAP compared with intra-arterial pressure. These results suggest that Nexfin may be used in low-to-moderate risk children without severe systemic hypotension, who require beat-to-beat haemodynamic monitoring but do not have an indication for invasive measurements. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
