Acid aspiration prophylaxis in Australian obstetric hospitals--a survey.
During 1987 a confidential survey of all hospitals in Australia providing obstetric services was undertaken to determine the antacid medications used routinely as prophylaxis against acid aspiration pneumonitis. Of the 567 hospitals surveyed, 379 (67%) responded. Of these, 243 hospitals provide an obstetric service which includes caesarean section, and 67% of these perform less than 500 deliveries per annum. ⋯ Results were similar in the emergency caesarean section group. The use of cimetidine or ranitidine was uncommon in all groups. Results of this survey suggest marked differences in attitudes towards acid aspiration prophylaxis between Australian and British obstetric anaesthetic practices.

Comparative StudyPostoperative analgesia in neonates: an Australia-wide survey.
An Australia-wide survey of the use of postoperative analgesia in neonates has been conducted. A high overall use of analgesia has been recorded with 75% of respondents prescribing an opioid. ⋯ The general attitude is that analgesia is desirable but a fear of respiratory depression inhibits its use, particularly in non-ventilated neonates and after more minor surgery. It is suggested that a wider use of regional anaesthesia techniques may reduce this problem.

The influence of CO2 production and physiological deadspace on end-tidal CO2 during controlled ventilation: a study using a mechanical model.
A mechanical lung model was used to investigate the effect of varying carbon dioxide production and deadspace on the end-tidal carbon dioxide levels achieved during mechanical ventilation when using the Bain, Humphrey ADE, and circle systems. Both factors had significant influence on end-tidal carbon dioxide concentration and could result in values in excess of those considered acceptable in clinical practice. The implications of the results are discussed.
