Abstract
DELGADO R, Martha B. et al. Nivel sensitivo calculado vs. observado en anestesia peridural con bupivacaína. Estudio de concordancia . Rev. colomb. anestesiol. [online]. 2006, vol.34, n.3, pp.149-153. ISSN 0120-3347.
Objectives: This study was designed to evaluate the concordance between measured and estimated sensitive level after epidural anesthesia with bupivacaine 0.5% and to validate the equation routinarily used to calculate total dose volume. Methods: Prospective conformity concordance study. Setting and participants: 77 patients, both gender, older than 17, scheduled for abdominal or lower limb surgery at San Ignacio University Hospital under epidural anesthesia with bupivacaine 0.5%. The total volume dose and the estimated sensitive level was calculated using the equation (7.8-(age x 0.03) x No. metameres) / 5, and 30 minutes after epidural dose administration the observed sensitive level was assessed. Then estimated sensitive level and measured sensitive level were compared. Results: The 95% agreement limits were calculated between measured sensitive level and estimated sensitive level. The mean difference was 2.23 levels and the limits were -2.39 and 6.84. 50% of patients had at least 2 levels upper than expected, and some people had 9 levels upper than estimated. Conclusions: There is a poor agreement between expected vs. observed level using the equation to estimate bupivacaine 0.5% volume dose.
