We measured afterdrop and peripheral tissue temperature distribution in eight patients cooled to approximately 17°C during cardiopulmonary bypass and subsequently rewarmed to 36.5°C. A nasopharyngeal probe evaluated trunk and head temperature and heat content. Peripheral tissue temperature (arm and leg temperature) and heat content were estimated using(More)
UNLABELLED Electromyographic (EMG) activity can contaminate electroencephalographic signals. Paralysis may therefore reduce the Bispectral Index (BIS) by alleviating artifact from muscles lying near the electrodes. Paralysis may also reduce signals from muscle stretch receptors that normally contribute to arousal. We therefore tested the hypothesis that(More)
OBJECTIVES Interagency Registry for Mechanical Assisted Circulatory Support (INTERMACS) Level I patients have the highest early mortality after ventricular assist device (VAD) implantation. This is determined by the exposure of patients in shock with acutely damaged end-organs and high catecholamine support to a significant surgical trauma. We report our(More)
BACKGROUND Magnesium is a calcium and an NMDA-receptor antagonist and can modify important mechanisms of nociception. We evaluated the co-analgesic effect of magnesium in the postoperative setting after on-pump cardiac surgery. METHODS Forty patients randomly received either magnesium gluconate as an i.v. bolus of 0.21 mmol kg(-1) (86.5 mg kg(-1))(More)
BACKGROUND High-dose remifentanil (1-5 microg kg-1 min-1), commonly used for cardiac surgery, has been associated with muscle rigidity, hypotension, bradycardia, and reduced cardiac output. The aim of this study was to determine an optimal lower remifentanil dose, which should be accompanied by fewer adverse events, that still effectively suppresses(More)
Background: Hypothermic and normothermic cardiopulmonary bypass (CPB) have resulted in apparently contradictionary cardiac and neurologic outcome. Cerebrovascular risk and cognitive dysfunction associated with normothermic CPB still remain uncertain. Materials and methods: In a prospective randomized study, we measured the effects of mildly hypothermic(More)
