| Research Abstract |
We investigated interactions between sugammadex and rocuronium, one of non-depolarizing neuromuscular blockers, in sepsis using a rat model of acute sepsis induced by cecal ligation and puncture (CLP). Adult male Wistar rats were assigned to a normal group or a group in which sepsis was surgically induced by CLP (CLP group). Twitch tension of hemidiaphragm removed from each rat was estimated while rocuronium or sugammadex was additively administered in each group. The concentration-twitch tension curve for rocuronium significantly shifted rightwards in the CLP group compared with the normal group, and the concentration-twitch tension curves for the administration of sugammadex significantly differed between the two groups. Sepsis attenuates the effects of rocuronium on twitch tension of the rat diaphragm and also attenuates the reversal effect of sugammadex on rocuronium-induced depression of twitch tension in vitro.
