[Mathematical analysis of relations between dose, level or volume of bupivacaine and various hemodynamic parameters in epidural anesthesia]. / Matematyczna ocena zaleznosci miedzy dawka, stezeniem lub objetoscia bupiwakainy a niektórymi parametrami hemodynamicznymi w znieczuleniu zewnatrzoponowym.

Changes in the basic, hemodynamic parameters during the first 30 minutes of epidural anesthesia in relation of the dose, concentration, and volume of bupivacaine used are discussed. It was found, that in a proper epidural anesthesia a significant effect on the value of basic hemodynamic parameters was exerted only by a volume of administered bupivacaine solution, whereas its concentration or dose do not play any significant role. However, further prospective studies are necessary to extend this observation on the wider population.
