BACKGROUND Continuous spinal anaesthesia with spinal catheters allows incremental dosing of local anaesthetic and, consequently, less haemodynamic changes. However, little is known about the required doses. Therefore, we designed a study to assess the minimum effective local anaesthetic dose (MLAD) of levobupivacaine and ropivacaine in this context.

BACKGROUND Dexmedetomidine is a potent and selective α2-adrenoceptor agonist used for perioperative and intensive care sedation with certain beneficial qualities. However, based on preclinical observations, it might inhibit gastric emptying and gastrointestinal transit, which could result in unwanted effects in intensive care patients. This study evaluated(More)
The pharmacokinetics of an i.v. bolus of propofol 2 mg kg-1 were studied in 10 uraemic patients undergoing renal transplantation and in seven healthy controls matched for age, weight and duration of anaesthesia. Haemodynamic changes during induction of anaesthesia were recorded in the uraemic and in 10 healthy control patients. Pharmacokinetic variables(More)
We studied seven healthy volunteers given itraconazole 200 mg orally or placebo, once daily for 4 days, in a crossover study. On day 4, racemic bupivacaine 0.3 mg kg-1 was given i.v. over 60 min and venous plasma samples were collected for 23 h. Plasma concentrations of R- and S-bupivacaine, itraconazole and hydroxyitraconazole were measured. Itraconazole(More)
A computerized infusion system was used to determine mivacurium infusion requirements to maintain 95% and 50% neuromuscular block in 15 infants less than 1 yr of age. Neuromuscular block was measured by adductor pollicis EMG and anaesthesia maintained with 66% nitrous oxide in oxygen and alfentanil 50-100 micrograms kg-1 h-1. Neuromuscular block was(More)
