| Abstract | BACKGROUND: This study describes a pharmacodynamic model during general anaesthesia in children relating the bispectral index (BIS) response to the anaesthetic dosing of propofol, fentanyl, and remifentanil. METHODS: BIS, heart rate, mean arterial pressure, sedation scores, and anaesthetic protocols from 59 children aged 1-16 yr undergoing general surgery were considered for the study. Anaesthesia was performed with propofol, fentanyl, and remifentanil. A sigmoid model assuming additive interaction of propofol, fentanyl, and remifentanil was fitted to individual BIS as effect variable. The pharmacodynamic parameters were estimated by non-linear regression analysis. The ability of BIS to predict anaesthetic drug effect was quantified by the prediction probability Pk. RESULTS: BIS started at a baseline of 90 (9), decreased during induction to 30 (14) and remained at 57 (10) during anaesthesia. BIS predicted the anaesthetic drug effect with a Pk of 0.79 (0.08). The EC(50 Propofol) and the k(e0 Propofol) were 5.2 (2.7) microg ml(-1) and 0.60 (0.45) min(-1), respectively. The k(e0 Propofol) decreased from approximately 0.91 min(-1) at 1 yr to 0.15 min(-1) at 16 yr. The EC(50 Remifentanil), k(e0 Remifentanil), EC(50 Fentanyl), and the k(e0 Fentanyl) were 24.1 (13.0) ng ml(-1), 0.71 (0.32) min(-1), 8.6 (7.4) ng ml(-1), and 0.28 (0.46) min(-1), respectively. CONCLUSIONS: The effect equilibration half-time of propofol in children was age dependent. The pharmacodynamics of fentanyl and remifentanil in children were similar to those reported in adults. The BIS showed a close relationship to the modelled effect-site concentration, and therefore, it may serve as a measure of anaesthetic drug effect in children older than 1 yr. |

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.
