Randomized Controlled Trial Comparative Study Clinical Trial
Recovery after day-case anaesthesia. A 24-hour comparison of recovery after thiopentone or propofol anaesthesia.
Sixty patients who presented for day-case dilatation and curettage were allocated randomly to receive either thiopentone or propofol for induction and maintenance of anaesthesia. One anaesthetist administered all the anaesthetics whilst all assessments were made by one other. ⋯ There was a significant difference in subjective feelings of tiredness and drowsiness recorded by the two study groups at 24 hours. Memory function assessed by Wechsler logical memory function passages at 24 hours was impaired in the propofol group in comparison to a group of 'reference' subjects.

Volume therapy with hypertonic saline hydroxyethyl starch solution in cardiac surgery.
The ideal solution for volume therapy remains controversial. In cardiac surgery, haemodynamic efficacy as well as the influence of extracorporeal oxygenation are of major interest when administering volume. The present study examines the effects of a new hypertonic saline hydroxyethyl starch solution in comparison to a 6% hydroxyethyl starch solution on haemodynamics and laboratory variables. ⋯ Patients in that group showed the highest decrease in total systemic resistance (-29.8%), whereas arterial pressure and right ventricular ejection fraction remained almost unchanged in all groups. No negative alteration in coagulation or organ function was demonstrated within the investigation period. It can be concluded that hypertonic saline hydroxyethyl starch solution seems to be a valuable alternative to conventional volume therapy in cardiac surgery.

Randomized Controlled Trial Comparative Study Clinical Trial
The laryngeal mask airway in paediatric anaesthesia.
Forty-eight children, aged between 2 and 10 years, admitted as day cases for otological surgery were allocated at random into two groups. The first group was anaesthetised using a standard facemask, and the second with a laryngeal mask airway. ⋯ Hypoxia was significantly less frequent in the laryngeal airway group (p less than 0.05), and there were significantly fewer interruptions to surgery than in the facemask group (p less than 0.001). Patient safety, operating and anaesthetic conditions were all considered superior in the laryngeal airway group.
