Non-invasive measurements of oxygen saturation are attractive because they provide continuous information which may result in improved patient care. We evaluated a new finger pulse oximeter as a measure of arterial oxygen saturation in critically ill patients with respiratory distress. In 12 patients studied, 133 simultaneous comparisons between in vivo(More)
Non-invasive measurements of oxygen saturation are attractive because continuous information is provided, which may result in improved patient care. We evaluated a new finger pulsoximeter as a measure of arterial oxygen saturation during fiberoptic intubation. Secondly, we studied the kinetics of oxygen-haemoglobin desaturation during the procedure. In 15(More)
To evaluate the accuracy of the method, sequential measurements (n = 159) of extravascular lung water (EVLW) using the thermo-dye double-indicator dilution technique were performed in 22 critically surgical ill patients. Radiographic grading of lung water content served as clinical standard. Normal mean EVLW defined radiographically without evidence of(More)
During endolaryngeal microsurgery, an attempt was made to quantify laryngeal muscle relaxation by electromyographic recording of evoked responses from the vocal cord musculature in 5 patients. Both mechanographic and electromyographic recordings from the adductor pollicis were obtained simultaneously. Following a bolus dose of vecuronium (60 micrograms/kg,(More)
Based on experiences with 256 kidney transplant operations in 239 patients over a period of ten years (18.6. 1965 to 15.4. 1975) the role of the anaesthesiologist as it had developed in our institution has been described. Some problems with regard to the anaesthetic management of living donors were discussed. The care of patients who, due to their(More)
The effects of 1000 ml 3.6% dextran Ringer's acetate solution (Mw 61,800; infusion time 60 min) on circulation, blood and plasma volume, blood viscosity and renal function parameters were investigated, the renal elimination of dextran also being measured. During the entire investigation period no significant alterations of cardiocirculatory parameters,(More)
Pre-operative "isovolaemic" haemodilution using 6% hydroxyethyl-starch was used in 7 patients with tumours involving the mouth. While the value of isovolaemic haemodilution in terms of reducing transfusion requirements with donor blood was confirmed, this positive effect was found to be offset by the narrow margin within which blood pressure can be reduced(More)
Changes in hemodynamics, plasma catecholamines, and PRA in response to controlled hypotension induced with ISDN (n = 10, mean dose 15.5 micrograms kg-1 min-1) and NTG (n = 7, mean dose 5.5 micrograms kg-1 min-1) were studied during neuroleptanesthesia in patients undergoing facial and neck surgery. Before the commencement of vasodilator infusion the(More)
The effects of intravenous isosorbide dinitrate (ISDN: 3, 6, 9, and 12 mg/h) on systemic and pulmonary vasculature, gas exchange, and dynamic lung compliance were investigated in 7 controlled ventilated patients suffering from ARDS after trauma or in sepsis. Parameters were recorded before and after 20 min. ISDN infusion with 30 min interruption between the(More)
