Clinical Trial Controlled Clinical Trial[Behavior of adrenaline, noradrenaline, blood pressure and heart rate in intubation in relation to different doses of fentanyl].
In 24 patients undergoing ENT surgery the reactions of blood pressure, heart rate and plasma catecholamines were studied during standardized induction of anaesthesia as well as after additional fentanyl administration of 0.1 or 0.2 mg before intubation. In the control group (n = 8) six measurements were performed, i.e. one minute before and after the administration of the drugs for induction, as well as immediately after the insertion of the laryngoscope and one minute after intubation. In the reference groups two measurements were performed: before induction of anaesthesia and one minute after intubation, in the period of maximal circulatory reaction. 0.1 or 0.2 mg were administered in the fentanyl groups (n = 8 in each) after precurarization before injecting thiopentone. ⋯ The administration of 0.1 mg fentanyl proved to be insufficient to depress the sympathoadrenergic reaction during intubation. Although plasma catecholamines did not rise, a marked increase in blood pressure and heart rate could not be avoided. The difference compared to 0.2 mg fentanyl was significant in the parameters blood pressure and heart rate (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Case Reports[Lesion of the brachial plexus, caused by wrong positioning during surgery].
We report three patients, which showed plexus palsies after routine operations. Compression and stretch of the nerves despite pads leaded to nerve injury in patient A. ⋯ Hyperreclination of the head in semisitting position caused the lesion in patient C. The anaesthetist should know the risks of positioning to prevent nerve injuries.
