Anaesthesia
-
Interventional cardiology is an innovative and expanding field. Anaesthetists are increasingly involved in managing complex congenital and acquired heart lesions in the cardiac catheterisation laboratory. This article provides an overview of common lesions encountered in the cardiac catheterisation laboratory, the anaesthetic management of patients with congenital and acquired heart lesions, the procedures performed and the complications encountered during such procedures.

Randomized Controlled Trial Comparative Study
A comparison of oral midazolam and nitrous oxide sedation for dental extractions in children.
The aim of the study was to compare oral midazolam and inhaled nitrous oxide as sedative agents during the management of children aged 5-10 years presenting for extraction of primary teeth under local anaesthetic. Subjects required two visits for the extraction of four primary teeth, one in each quadrant of the mouth, and were randomly allocated to be given nitrous oxide 30% in oxygen or oral midazolam 0.3 mg.kg(-1) at the first visit, the other technique being used at the second visit. Vital signs, sedation levels and behavioural scores were recorded, and postoperative recall and satisfaction were reported by the patients. ⋯ Physiological parameters remained within acceptable clinical limits for both types of sedation. Oral midazolam was considered acceptable by 59% and was preferred by 36%. Oral midazolam sedation in 5 to 10-year-old children was shown to be as safe and effective as nitrous oxide in oxygen sedation for extraction of primary teeth but would not be the method of choice for all patients.
