Anaesthesia and intensive care

This survey was designed to evaluate the factors affecting mental health and welfare in Australian anaesthetists and to investigate current sources of support. An electronic survey was sent to 500 randomly selected Fellows and trainees of the Australian and New Zealand College of Anaesthetists. Questions were related to: anxiety, stress, depression, substance misuse, self-medication, suicide, reporting illness, and help-seeking. ⋯ Despite a low response rate, and the possibility of responder bias, the mental health of Australian anaesthetists would appear to be subject to common and persistent risk factors, many of which are well described in previous studies. We identify general practitioners as particularly valuable in targeting initiatives for improvements in mental health and welfare. The significant prevalence of suicidal ideation and reluctance to approach senior colleagues with concerns about mental health or welfare issues are specific causes for concern and suggest that further investigation, education and a potential review of support networks is required.

Cricothyroidotomy is infrequently performed in the intensive care unit but may be a lifesaving procedure. The aim of this study was to determine the number of attempts required by trainees to gain adequate skills for a successful cricothyroidotomy (defined as lung inflation <60 seconds). The effect of training on time to completion of cricothyroidotomy was also studied. ⋯ Age, years of postgraduate practice and level of seniority appeared to be associated with earlier success. Consecutive attempts on a manikin led to an improvement in the time to completion of cricothyroidotomy and rate of a successful outcome (<60 seconds). We recommend that clinicians undergo at least five training attempts on a manikin to gain proficiency in cricothyroidotomy.

Approaches to learning for the ANZCA Final Examination and validation of the revised Study Process Questionnaire in specialist medical training.
When evaluating assessments, the impact on learning is often overlooked. Approaches to learning can be deep, surface and strategic. To provide insights into exam quality, we investigated the learning approaches taken by trainees preparing for the Australian and New Zealand College of Anaesthetists (ANZCA) Final Exam. ⋯ Minimal reference was made to the ANZCA syllabus as a guide for learning. These findings indicate that, although trainees found the exam generally relevant to practice and adopted predominantly deep learning approaches, there was considerable variation between the four components. These results provide data with which to review the existing ANZCA Final Exam and comparative data for future studies of the revisions to the ANZCA curriculum and exam process.

Randomized Controlled TrialDuration of cortisol suppression following a single dose of dexamethasone in healthy volunteers: a randomised double-blind placebo-controlled trial.
The synthetic glucocorticoid dexamethasone is administered to many patients receiving a general anaesthetic to reduce the risk of postoperative nausea and vomiting. Dexamethasone is known to suppress the hypothalamic-pituitary-adrenal axis; however, the duration of this suppression following the standard anti-emetic intravenous dose of 4 to 8 mg used with anaesthesia is unknown. A randomised controlled double-blind crossover trial assessing the effects of 8 mg intravenous dexamethasone versus saline control was performed in ten healthy male volunteers. ⋯ Increased plasma glucose levels were also observed in the dexamethasone group as compared with placebo. A dose of 8 mg of dexamethasone results in significant suppression of the hypothalamic-pituitary-adrenal axis and elevated plasma glucose levels. The cortisol suppression is maximal at approximately 24 hours post dose.

Case ReportsNerve sheath catheter analgesia for forequarter amputation in paediatric oncology patients.
In a single centre over two years, four children (7 to 10 years old) with upper limb osteosarcoma underwent chemotherapy followed by forequarter amputation. All patients had preoperative pain and were treated with gabapentin. ⋯ Three of the four patients were successfully treated as outpatients with the nerve sheath catheters in situ. All four children experienced phantom limb pain; however, it did not persist beyond four weeks in any patient.
