PURPOSE To investigate changes of continuous mixed venous oxygen saturation (cSvO(2)) and mean arterial blood pressure (MBP) in dogs with bupivacaine-induced cardiac depression. METHODS Bupivacaine was infused into pentobarbital-anesthetized mongrel dogs (n = 8) at a rate of 0.5 mg.kg(-1).min(-1) until the MBP was 40 mmHg or less (end of bupivacaine(More)
