Effect of training on the scope of oral and maxillofacial surgery.
The relationships between training and qualifications and the scope of oral and maxillofacial surgical practice was investigated by a survey of all full members of the Australian and New Zealand Association of Oral and Maxillofacial surgeons. It was found that scope did correlate to length of training. Three were differences in scope for more recently trained surgeons and by practice location. The possession of medical qualification did not necessarily affect scope of practice but did affect attitudes.

Airway occlusion pressure (P0.1)-a useful predictor for the weaning outcome in patients with acute respiratory failure-.
Twenty-five patients who required mechanical ventilatory support (MVS) after major surgery or severe burns were studied to determine whether airway occlusion pressure (P(0.1)) is a clinically useful indicator to predict the success or failure of the weaning trial. A total of 33 weaning trials were attempted on these patients. Of the 33 trials, 24 were followed by successful weaning and 9 by failure. ⋯ The alveolar-arterial P(O)(2) gradient, with an F i(O)(2) of 1.0, in weaning success and failure showed no statistical difference. In contrast, all patients in the success group had a P(0.1) of less than 3.5 cmH(2)O and those in the failure group had a P(0.1) of greater than 3.5 cmH(2)O ( P < 0.001). We conclude that P(0.1) is a clinically superior indicator for discontinuing MVS in patients with acute respiratory failure.

Perioperative monitoring of the electrocardiogram during cerebral aneurysm surgery.
Electrocardiographic (ECG) abnormalities occur frequently following a subarachnoid hemorrhage and may also occur intraoperatively and postoperatively in patients undergoing neurovascular procedures. The aim of this study was to assess the relationship between ECG changes and the neurological status of the patient, the size and the location of the aneurysm, and the influence of these changes on the cardiac and neurological outcome. The preoperative ECG was analyzed in 270 patients. ⋯ Intraoperative and postoperative changes occurred in 35 and 65% of the patients, respectively, and were independent of the studied factors. There were no documented cardiac events. The presence of an abnormal preoperative ECG did not influence the neurological outcome of the patient, but fluctuating postoperative changes were associated with a worse outcome.
