Randomized Controlled Trial Clinical Trial
[Pre-emptive analgesia with ropivacaine in adult tonsillectomy].
We examined whether a pre-emptive analgesic effect could be achieved with ropivacaine, which has less cardiovascular and central nervous system toxicity than bupivacaine, in adults undergoing tonsillectomy. ⋯ We could demonstrate no significant pre-emptive analgesic effect with ropivacaine in adults undergoing tonsillectomy in our study. One can, however, recommend the administration of ropivacaine post-operatively after tonsillectomy, since a reduction of pain scores can thereby be achieved. For post-operative analgesia we recommend the combination of a non-opioid analgesic with a weak opioid.

Randomized Controlled Trial Comparative Study Clinical Trial
[Anesthesia in geriatric patients. The determination of physiological variables for cognitive function in geriatric patients after regional or general anesthesia].
The aim of the present study was to show the influence of the parameters of gas exchange (arterial oxygen pressure paO2, arterial oxygen saturation SatO2) and haemodynamics (arterial systolic and mean blood pressure RRs and MAP) on the restitution of cognitive functions in geriatric patients scheduled for elective hip arthroplasty. ⋯ The restitution of cognitive functions during the first three postoperative days in geriatric patients scheduled for elective hip surgery does not depend on the anaesthetic technique. According to our results regional anaesthesia does not show any advantage for geriatric patients undergoing elective hip arthroplasty.
