BACKGROUND AirSeal is a novel class of valve-free insufflation system that enables a stable pneumoperitoneum with continuous smoke evacuation and carbon dioxide (CO₂) recirculation during laparoscopic surgery. Comparison data to standard CO₂ pressure pneumoperitoneum insufflators is scarce. The aim of this study is to evaluate the potential advantages of… (More)
Between January 1975 and December 1984, 239 patients after breast conserving surgery were referred to the University Clinic for Radiotherapy and Radiobiology of Vienna. Of these patients 214 were available for analysis with regard to loco-regional control and cosmetic outcome. The breast received supervoltage irradiation from two tangential fields, in 82%… (More)
BACKGROUND Stenotic processes of the tracheobronchial system may lead to dyspnoea that can become lift-threatening. To restore sufficient function of the blocked airway, a silicone stent can be inserted. The anaesthesia techniques used for this intervention so far have been complicated. The object of this study was to determine whether the super-imposed… (More)
Continuous measurements of transcutaneous PO2 are of interest in pulmonary function tests by which dynamic processes of pulmonary gas exchange are examined. The aim of the present study is to clarify the question of whether the transition function of transcutaneous PO2 after a step change of inspiratory oxygen concentration could give information about… (More)
The plasma level of etidocaine was studied within the first two hours of axillary block in 7 patients with renal insufficiency and 7 healthy adults. After 15-20 min the maximum of plasma concentration was found in the group with renal failure and after 30-45 min in the healthy adults. 30 min after the block the plasma level was 1,26 +/- 0,62 mug/ml in the… (More)
In intensive care medicine the tcPO2 measurement can be used efficiently if the problems discussed are taken into consideration. The advantages of the method follow. 1) The trend of the arterial PO2 can be monitored continuously. 2) A large fall in tcPO2 can be a sign of arterial PO2 decrease or of circulatory insufficiency.
The incidence of persistent occipitoposterior positions (POP-positions) during the period from 1969-76 in 7,469 vaginal deliveries was studied with respect to the influence of epidural anaesthesia (EA), parity and age. The EA-group consisting of 1,553 deliveries showed a higher number of POP-positions (4.3%) than in the two control-groups without EA (2.8%,… (More)
