Randomized Controlled Trial Comparative Study Clinical Trial
Postoperative sore throat: topical hydrocortisone.
Forty patients undergoing tracheal intubation and controlled ventilation of the lungs for elective surgical procedures were studied. They were allocated randomly into one of two groups. ⋯ The incidence of postoperative sore throat was found to be significantly greater in group A. Topical 1% hydrocortisone cream is therefore ineffective in the prevention of postoperative sore throat.

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.

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.

The Level 1 blood warmer series comprises three infusion sets and two blood warmers of different power outputs. All systems were found to be extremely efficient, with the larger 500 series capable of warming the equivalent of 80 units of blood an hour almost to body temperature.
