A unique snapshot of intensive care resources in Australia and New Zealand.
The objective of this study was to analyse and report on the distribution and attributes of intensive care services in Australia and New Zealand for the 2005/2006 financial year A survey was mailed to 155 Australian and 26 New Zealand intensive care units (ICU) listed on the database of the Australian and New Zealand Intensive Care Society. A descriptive analytical approach was used. ⋯ These units contain 1485 available beds in the public sector and 538 available beds in the private sector Calculations to determine beds per 100,000 population, medical specialists per 1000 patient days and registered nurses per 1000 patient days showed wide variation. International comparisons are limited by lack of data; however it does appear that intensive care patients in Australia and New Zealand have very good outcomes.

Randomized Controlled TrialA randomised comparison of parecoxib versus placebo for pain management following minor day stay gynaecological surgery.
At therapeutic concentrations, parecoxib selectively inhibits the cyclo-oxygenase-2 enzyme. We investigated the impact of a single preoperative dose of parecoxib on pain relief following minor gynaecological surgery. Ninety women undergoing uterine dilatation and curettage, with or without hysteroscopy, were randomised to receive either 40 mg of parecoxib intravenously or a saline placebo prior to induction of standardised general anaesthesia. ⋯ The 24 hour Quality of Recovery score did not differ significantly between groups but the parecoxib group was less likely to experience headache at 24 hours postoperatively (12 vs. 38%, P = 0.007) and reported complete satisfaction more frequently (78 vs. 57%, P = 0.042). The preoperative administration of parecoxib was associated with a significant but small decrease in dynamic pain scores one hour postoperatively. Women who received preoperative parecoxib had a lower incidence of postoperative headache and higher satisfaction.

Randomized Controlled TrialFentanyl dose for the insertion of Classic Laryngeal Mask Airways in non-paralysed patients induced with propofol 2.5 mg/kg.
The aim of this randomised, controlled trial was to determine the optimum dose of fentanyl in combination with propofol 2.5 mg x kg(-1) when inserting the Classic Laryngeal Mask Airway. Seventy-five ASA I or II patients were randomly assigned to five groups of fentanyl dosage: 0 microg x kg(-1) (placebo), 0.5 microg x kg(-1), 1.0 microg x kg(-1), 1.5 microg x kg(-1) and 2.0 microg x kg(-1). Anaesthesia was induced by first injecting the study drug over 10 seconds. ⋯ We found that there was a high rate of successful first attempt at insertion with 1 microg x kg(-1) and 1.5 microg x kg(-1), 93% and 87% respectively, compared to 87% in the 2.0 microg x kg(-1) group. The 1.0 microg x kg(-1) group also achieved an 80% optimal insertion conditions score of 4, compared to 73% in the 1.5 microg x kg(-1) group and 80% in the 2 microg x kg(-1) group. Therefore we recommend 1.0 microg x kg(-1) as the optimal dose of fentanyl when used in addition to propofol 2.5 mg/kg for the insertion of the Classic Laryngeal Mask Airway.

Clinical TrialMagnesium sulphate for treatment of tetanus in adults.
There are reports that suggest that magnesium sulphate alone may control muscle spasms thereby avoiding sedation and mechanical ventilation in tetanus, but this has not been confirmed. We examined the efficacy and safety of intravenous magnesium sulphate for control of rigidity and spasms in adults with tetanus. A prospective clinical study of intravenous magnesium sulphate was carried out over a period of two years in a tertiary care teaching hospital. ⋯ The average duration of ventilatory support was 18.3 +/- 16.0 days and the overall mortality was 22.9%. Asymptomatic hypocalcaemia was a universal finding. Magnesium sulphate therapy alone may not be efficacious for the treatment of severe tetanus.
