Aim Of The Study: We investigated the pharmacodynamic effects of the phosphodiesterae inhibitor enoximone in the presence of halothane and isoflurane in 20 patients, ASA class III, aged 45-75 years, undergoing coronary artery bypass grafting. The study was approved by the local Medical Ethics Committee and patients' informed written consent was obtained.
Methods: After induction of anaesthesia (midazolam, fentanyl, etomidate and pancuronium) all patients received either halothane 1 MAC (group I, n = 10) or isoflurane 1 MAC (group II, n = 10), followed 20 min later by enoximone 0.
We have investigated the circulatory effects of halothane and isoflurane in the presence of the phosphodiesterase inhibitor, enoximone, in 20 patients, ASA class III, aged 40-70 yr, undergoing coronary artery bypass grafting. After induction of anaesthesia (midazolam, fentanyl, etomidate and pancuronium) all patients received enoximone 0.5 mg kg-1, followed, 10 min later, by either halothane 1 MAC (group I; n = 10) or isoflurane 1 MAC (group II; n = 10).
