Creatine kinase (CK) and its brain-specific isoenzyme (CK-BB), neuron-specific enolase (NSE), neural cell adhesion molecule (NCAM) and the ions sodium, potassium, chloride and calcium were measured both in CSF and serum and inorganic phosphate in CSF in order to assess their prognostic value in total brain ischemia due to cardiac arrest. The samples were(More)
BACKGROUND Preservation of right ventricular myocardium is unsatisfactory in patients with critical stenosis or occlusion of the right coronary artery. The aim of this study was to investigate whether ischemic preconditioning (IP) improved the recovery of right ventricular function after coronary artery bypass grafting. METHODS Forty patients with(More)
BACKGROUND Operations are typically associated with sleep and other circadian rhythm disturbances. The present study was set up to evaluate the influence of spinal and general anaesthesia associated with knee surgery on the circadian rhythm of melatonin, which has sleep inducing properties. Previously this context has been studied only in some invasive(More)
OBJECTIVES We intended to investigate whether ischemic preconditioning (IP) enhances myocardial performance in patients who undergo off-pump coronary artery bypass grafting (CABG). DESIGN A controlled, randomized, prospective study. SETTING A university hospital. PATIENTS Thirty-two patients with left anterior descending coronary artery (LAD) or(More)
OBJECTIVE The release of proinflammatory cytokines has been shown to be associated with the development of complications after coronary artery bypass grafting with cardiopulmonary bypass. The purpose of the present study was to establish whether ischemic preconditioning (IP) could limit inflammatory cytokines release in patients undergoing elective coronary(More)
OBJECTIVE To evaluate the reliability of whole-body impedance cardiography with electrodes on wrists and ankles in the measurement of cardiac output compared with the thermodilution method. DESIGN Prospective, clinical investigation. SETTING Surgical intensive care unit and operating room at a university hospital. PATIENTS Simultaneous cardiac output(More)
To study the possible benefits of N2O pneumoperitoneum, 40 patients scheduled for laparoscopic cholecystectomy for symptomatic cholelithiasis were randomized into either CO2-induced (n = 20) or N2O-induced (n = 20) pneumoperitoneum groups. The intensity of postoperative pain was assessed by the patients themselves using an visual analogue pain score scale.(More)
Cardiovascular and hormonal responses to aortic cross-clamping (ACC) and declamping (ADC) were studied in 20 patients undergoing reconstructive aortic surgery anesthetized with fentanyl and droperidol. Ten of the patients served as a control group, and 10 patients were treated with oral captopril (25 mg the day before operation and 25 mg one hour before(More)
The EEG of ten elective abdominal surgery patients was studied during halothane anaesthesia. The EEG was analysed by compressed spectral array. The total power and various power bands were analysed. Anaesthesia was induced by mask with halothane in air. EEG analysis was performed from the data collected before induction and during anaesthesia at steady(More)
OBJECTIVE Cardiopulmonary bypass is acknowledged to be one of the major causes of a complex systemic inflammatory response after cardiac surgery, and it may contribute to postoperative complications and even multiple organ dysfunction. We here compared the cytokine responses and the degree of myocardial injury after coronary artery bypass grafting with or(More)
