Randomized Controlled Trial Clinical Trial
Intravenous ketamine attenuates arterial pressure changes during the induction of anaesthesia with propofol.
To investigate whether the administration of ketamine before induction with propofol produces a smaller decrease in arterial pressure. ⋯ Administration of ketamine before induction with propofol preserved haemodynamic stability compared with induction with propofol alone.

Clinical Trial
The plasma elimination rate and urinary secretion of procalcitonin in patients with normal and impaired renal function.
The amount of procalcitonin eliminated in the urine and the plasma disappearance rate of procalcitonin were evaluated in patients with normal and impaired renal function, because patients with sepsis are a main target group for procalcitonin measurement, and these patients often develop renal dysfunction. ⋯ Renal elimination of procalcitonin is not a major mechanism for procalcitonin removal from the plasma. Although the plasma disappearance rate may be prolonged up to 30-50% in some patients with renal dysfunction, clinical diagnostic decisions may not be severely influenced by this moderate prolongation of procalcitonin elimination. We conclude that procalcitonin can be used diagnostically in patients with renal failure as well as in those with normal renal function.

Randomized Controlled Trial Clinical Trial
Interscalene brachial plexus anaesthesia with small volumes of ropivacaine 0.75%: effects of the injection technique on the onset time of nerve blockade.
We evaluated the effect of the injection technique on the onset time and efficacy of interscalene brachial plexus anaesthesia. ⋯ We conclude that using a multiple injection technique shortened the preparation time and improved the quality of interscalene brachial plexus anaesthesia performed with small volumes of ropivacaine 0.75%.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of remifentanil and fentanyl in patients undergoing carotid endarterectomy.
We investigated the haemodynamic stability and emergence characteristics of isoflurane/nitrous oxide anaesthesia supplemented with remifentanil or fentanyl in patients undergoing carotid endarterectomy. ⋯ Remifentanil appears to be a comparable opioid to fentanyl when supplementing isoflurane/nitrous oxide anaesthesia for carotid endarterectomy.
