The new Diploma of Rural Generalist Anaesthesia: Supporting Australian rural and remote communities.
In 2023, a Diploma of Rural Generalist Anaesthesia (DipRGA) was implemented across Australia. Developed collaboratively by the Australian and New Zealand College of Anaesthetists (ANZCA), the Australian College of Rural and Remote Medicine (ACRRM) and the Royal Australian College of General Practitioners (RACGP), the 12-month qualification is completed during or following ACRRM or RACGP Rural Generalist Fellowship training. Focused on the needs of rural and remote communities for elective and emergency surgery, maternity care, resuscitative care for medical illness or injury, and stabilisation for retrieval, the DipRGA supports rural generalist anaesthetists working within collaborative teams in geographically isolated settings. ⋯ Curriculum content is addressed in seven entrustable professional activities supported by workplace-based assessments and multisource feedback. Trainees are supervised by rural generalist anaesthetists and specialist anaesthetists, and complete flexible learning activities to accommodate geographical dispersion. Standardised summative assessments include an early test of knowledge and an examination, adapted from the ACRRM structured assessment using multiple patient scenarios.

ReviewAirway management of lingual tonsillar hypertrophy: A narrative review.
Lingual tonsillar hypertrophy is rarely identified on routine airway assessment but may cause difficulties in airway management. We conducted a narrative review of case reports of lingual tonsillar hypertrophy to examine associated patient factors, success rates of airway management techniques and complications. We searched the literature for anaesthetic management of cases with lingual tonsillar hypertrophy. ⋯ Our findings show that severe cases of lingual hypertrophy may cause an unanticipated difficult airway and serious complications, including hypoxic brain damage and death. A robust airway strategy is required which includes limiting the number of attempts at laryngoscopy, and early priming and performance of emergency front of neck access if required. In patients with known severe lingual tonsillar hypertrophy, awake intubation should be considered.

Preliminary pharmacokinetics and patient experience of jet-injected dexmedetomidine in healthy adults.
Jet injection is a drug delivery system without a needle. A compressed liquid drug formulation pierces the skin, depositing the drug into the subcutaneous or intramuscular tissues. We investigated the pharmacokinetics and patient experience of dexmedetomidine administered using jet injection in six healthy adult study participants. ⋯ The Richmond agitation sedation scale was used to assess the sedative effect, and scored 0 (alert and calm) or -1 (drowsy) in all participants. Five of the six participants stated they would prefer jet injection to needle injection in the future and one had no preference. The findings suggest that the use of a larger dose (>2 μg/kg) would be required to achieve the clinically relevant target concentration of 1 μg/l necessary to achieve deeper sedation (Richmond agitation sedation scale ≤3).

There is a paucity of literature describing the research productivity among trainees in intensive care medicine. We sought to examine the occurrence and determinants of successful publication outcomes associated with intensive care training. The study cohort consisted of all individuals admitted to fellowship of the College of Intensive Care Medicine of Australia and New Zealand (CICM) from 2012 to 2019. ⋯ Although gender and location at the time of fellowship award were not associated, location of receipt of medical degree, shorter time period between medical school graduation and fellowship award, more recent year of award, and completion of medical degree/fellowship in the same geographical region were associated with project publication. A minority of CICM fellows have PubMed-indexed publications related to their training. Further efforts are warranted to better define the determinants of successful project publication to optimise future opportunities.

Randomized Controlled TrialInflammation risk before cardiac surgery and the treatment effect of intraoperative dexamethasone.
Patients who exhibit high systemic inflammation after cardiac surgery may benefit most from pre-emptive anti-inflammatory treatments. In this secondary analysis (n = 813) of the randomised, double-blind Intraoperative High-Dose Dexamethasone for Cardiac Surgery trial, we set out to develop an inflammation risk prediction model and assess whether patients at higher risk benefit from a single intraoperative dose of dexamethasone (1 mg/kg). Inflammation risk before surgery was quantified from a linear regression model developed in the placebo arm, relating preoperatively available covariates to peak postoperative C-reactive protein. ⋯ No treatment-effect heterogeneity was detected for the main clinical outcome (P = 0.167 for interaction). Overall, risk predictions from a model of inflammation after cardiac surgery were associated with the degree of peak postoperative C-reactive protein reduction derived from dexamethasone treatment. Future work should explore the impact of this phenomenon on clinical outcomes in larger surgical populations.
