Case ReportsIntraoperative 'pressure field' haemodynamic monitoring in a patient with severe aortic regurgitation having laparoscopic robot-assisted colorectal surgery.
Laparoscopic robot-assisted colorectal surgery can pose significant haemodynamic challenges for patients with severe aortic regurgitation. The increased afterload caused by pneumoperitoneum and aortic compression, along with concurrent factors like hypercarbia, Trendelenburg positioning and ventilatory impairment, can worsen aortic regurgitation, leading to myocardial ischaemia and heart failure. ⋯ Minimally invasive haemodynamic monitoring enabling real-time visualisation of a patient's 'pressure field' has been suggested as a potential adjunct or alternative to TOE, with the added advantage of providing continuous quantitative information about both stroke volume and the afterload to ventricular ejection in a single visualisation. We describe an example of successful concurrent use of pressure field haemodynamic monitoring and TOE in a patient with severe aortic regurgitation having a prolonged laparoscopic robot-assisted pelvic exenteration.

A cross-sectional study of the relationship between iron deficiency anaemia and chronic pain.
Iron deficiency and iron deficiency anaemia are frequently under-recognised in chronic conditions with non-specific symptoms, including fatigue. This study aimed to assess the prevalence of iron deficiency with or without anaemia in chronic pain patients, and the association between iron deficiency status, fatigue and health-related quality of life. Eighty-two patients attending chronic pain outpatient appointments were recruited into this cross-sectional study. ⋯ There was no significant association between iron deficiency status and the functional assessment of chronic illness therapy fatigue scale score or 36-item short form survey domain scores. There was a high prevalence of iron deficiency in this group of chronic pain patients, while the prevalence of iron deficiency anaemia was low. There was no statistically significant association found between iron deficiency status and fatigue or quality of life measures.

A comprehensive audit of difficult airway trolleys in selected Victorian hospitals.
This study aimed to assess the availability, design, and contents of difficult airway trolleys in hospitals in Victoria, Australia. A survey audit was conducted with a 92.3% reply rate, and the responses from 22 major Victorian hospitals were analysed. The results showed that difficult airway trolleys were available in 100% of operating theatres, emergency departments and intensive care units, and the rate of standardisation was high. ⋯ The carriage of non-essential items was reduced compared with earlier audits. However, there was heterogeneity in the brands of supraglottic airway devices, videolaryngoscopes and cognitive aids used. The study highlights the need for ongoing improvement to the organization and content of difficult airway trolleys, and for further discussion regarding the safety of equipment variation across institutions.

Promoting behavioural change by educating anaesthetists about the environmental impact of inhalational anaesthetic agents: A systematic review.
Of the total carbon footprint of Australia, 7% is attributed to healthcare. In the UK, inhalational agents make up 5% of the healthcare carbon footprint. This systematic review aims to determine which methods of education about the environmental impact of inhalational anaesthetic agents can be utilised to promote behaviour change, reducing the anaesthetic-related carbon footprint. ⋯ The most common teaching techniques utilised in education curricula were didactic lectures (85%), visual prompts (54%), emails (46%), and conversation forums (31%). All but one study reported a positive relationship between teaching sessions and behavioural change resulting in lower inhalational anaesthetic use by participants and their organisations, reducing healthcare-associated emissions. This systematic review has demonstrated that single education sessions as well as multi-focused, multimodal education curricula on the topic of greener anaesthesia can be beneficial in promoting behavioural change.
