Paediatric anaesthesia is made easier and safer by use of the correct equipment. The widening range and increasing complexity of available apparatus makes it essential for the anaesthetist to judge which items are most useful in any individual case. As a general rule, the simplest pieces of equipment are the most reliable and among the most useful.

Randomized Controlled Trial Clinical Trial
Continuous monitoring of blood glucose concentration during open-heart surgery.
Continuous monitoring of blood glucose concentration was compared with frequent intermittent sampling in 12 non-diabetic adult patients undergoing open-heart surgery with cardiopulmonary by-pass using priming fluids free of glucose. Continuous monitoring revealed several changes which were not detected on intermittent sampling. ⋯ Rewarming from hypothermic by-pass was associated with a 3 (+/- 0.5)-mmol litre-1 increase in blood glucose concentration (P less than 0.01). Commencement of infusions of sympathomimetic agents resulted in a similar increase.

Randomized Controlled Trial Clinical Trial
Comparison of diazepam and midazolam for sedation during local anaesthesia for bronchoscopy.
Bronchoscopy was performed in 76 outpatients using local anaesthesia plus diazepam 0.2 mg kg-1 i.v. or midazolam 0.05 or 0.1 mg kg-1 i.v. Patient co-operation and ease of bronchoscopy were good in all patients. ⋯ Two hours after sedation, the patients' performances in three psychomotor tests were similar to those measured before sedation in each group, but the patients' ability to stand steadily and walk along a straight line reverted to normal significantly (P less than 0.05) more slowly in patients receiving midazolam 0.1 mg kg-1 than in the patients given diazepam. The results suggest that midazolam offers no advantage over diazepam in terms of speed of recovery of psychomotor function, when doses of similar potency are given for bronchoscopy.
