Risks of regional anaesthesia for caesarean section: women's recall and information sources.
Recall and information sources regarding the risks of regional anaesthesia in women having lower segment caesarean section have not been adequately assessed previously. We aimed to survey women's recall of their pre-anaesthesia risk discussion and determine where women, presenting for lower segment caesarean section under regional anaesthesia, obtain risk information. Following a small pilot survey, women's responses were recorded for "spontaneous" or "prompted" recalled risks, the information source and its reliability. ⋯ Of those women giving at least four spontaneous responses, 41 (58.6%) had elective and 26 (32.5%) had emergency lower segment caesarean section (P = 0.001). The majority of women stated that anaesthetists were the main, and most reliable, source of their information regarding risks of regional anaesthesia for caesarean section. This report identifies the risks associated with regional anaesthesia for caesarean section that women most frequently recall, namely headache, paralysis, nerve damage and inadequate block.

Comparative StudyTrends in intra-aortic balloon counterpulsation: comparison of a 669 record Australian dataset with the multinational Benchmark Counterpulsation Outcomes Registry.
The aim of this study was to review and describe indications for intraaortic balloon counterpulsation (IABP) use and identify the impact these have on outcomes at an Australian cardiothoracic tertiary referral hospital. A secondary aim was comparison of the Australian practice with a large multinational IABP data registry. Patient demographics, IABP indication, IABP complication rate and mortality in 662 patients treated with IABP at The Prince Charles Hospital (TPCH), Brisbane, between January 1994 and December 2004 inclusive were compared with The Benchmark Counterpulsation Outcomes Registry. ⋯ TPCH indications for IABP were: weaning from cardiopulmonary bypass (34.2%); cardiogenic shock (24.4%); preoperative support (13%); catheter laboratory support (10.6%); refractory ventricular failure (7.3%); ischaemia related to intractable ventricular arrhythmias (4.5%); unstable refractory angina (4%); mechanical complications due to acute myocardial infarction (1.2%) and other (0.4%) (0.4% not reported). In comparison to Benchmark, IABP at TPCH demonstrated a prejudice toward intraoperative use (34.2% versus 16.6%; P < or = 0.0001) and an aversion to catheter laboratory support (10.6% versus 19%; P < or = 0.0001). TPCH and Benchmark IABP outcomes demonstrated comparable mortality (22% versus 20.8%; P = ns) but increased TPCH complications (10.3% vs. 6.2%; P < or = 0.0001) owing to a 2% difference in observed insertion site bleeding.

Case ReportsTranstracheal lignocaine: effective treatment for postextubation stridor.
Three cases of post-extubation stridor due to suspected laryngospasm are described in which a small dose of lignocaine injected intra-tracheally, through the cricothyroid membrane, produced rapid and effective relief of stridor with no early recurrence or side-effects. The procedure was performed safely and quickly and was well tolerated by patients. Trans-tracheal injection of local anaesthetic should be considered for treatment of post-extubation stridor in adults, so long as there is no risk of pulmonary aspiration, and pathological causes of laryngospasm have been excluded.
