Perioperative pulse oximetry was performed on one hundred consecutive abdominal surgical patients to audit our management of perioperative oxygenation. Oximetry was performed preoperatively, in the recovery room, and daily in the ward until discharge or the sixth postoperative day, with prescribed oxygen therapy continuing during measurement. ⋯ In this group of patients, clinical assessment of oxygenation and the need for oxygen therapy was inadequate. Intermittent oximetry is rapidly and simply performed, and by detecting patients with arterial haemoglobin desaturation, could improve oxygen prescribing in the perioperative period.

Randomized Controlled Trial Comparative Study Clinical Trial
Cardiovascular effects of fibrescope-guided nasotracheal intubation.
The cardiovascular effects of fibrescope-guided nasotracheal intubation were compared to those of a control group of patients who were intubated using the Macintosh laryngoscope. The 60 patients studied received a standard anaesthetic technique which included a muscle relaxant and were allocated randomly to one of two groups immediately before tracheal intubation. Systolic and diastolic arterial pressures in the fibreoptic group were significantly lower than in the control group during the first minute after intubation. ⋯ The heart rate in the fibreoptic group was significantly higher than in the control group during all five minutes after intubation. The maximum increase in heart rate was significantly higher in the fibreoptic group. The cardiovascular responses to fibreoptic nasotracheal intubation under general anaesthesia should not cause undue concern in fit patients, but appropriate measures should be taken to prevent excessive tachycardia in compromised patients.

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.
