The administration of local anesthesia in intraperitoneal space as part of the multi-modal analgesic regimen has shown to be effective in reducing postoperative pain. Recent studies demonstrated that intraperitoneal lidocaine may provide analgesic effects. Primary objective was to determine the impact of intraperitoneal lidocaine on postoperative pain scores at rest. ⋯ In this review, our findings should be interpreted with caution. Future studies are warranted to determine the optimal dose of administering intraperitoneal lidocaine among adult patients undergoing surgery.

Lumbar and sacral tattoos are popular amongst all ages. Some physicians are concerned that passing a needle through a pigmented area during lumbar puncture may deposit toxic material into the central nervous system, resulting in late complications. ⋯ There is insufficient evidence to endorse placement of a needle through a tattoo into the neuraxis before it is completely healed. The Fermi paradox 'absence of evidence is not evidence of absence of effect' still holds in light of emerging evidence that tattoos may be linked to lymphoma.

Most of science involves making observations, forming hypotheses, and testing those hypotheses, to form valid conclusions. However, a distinct, longstanding, and very productive scientific approach does not follow this paradigm; rather, it begins with a screen through a random collection of drugs or genetic variations for a particular effect or phenotype. ⋯ This review explains the rational for forward screening approaches and uses examples of screens for mutants with altered anesthetic sensitivities and for novel anesthetics to illustrate the methods and impact of the approach. Forward screening approaches are becoming even more powerful with advances in bioinformatics aided by artificial intelligence.

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.

ReviewThe Fontan Circulation in Pregnancy: Hemodynamic Challenges and Anesthetic Considerations.
Pregnancy in patients with Fontan physiology presents unique challenges due to altered cardiovascular dynamics inherent to both conditions. The Fontan procedure reroutes venous blood directly to the pulmonary arteries, bypassing the heart, and necessitating precise regulation of pulmonary venous resistance and systemic venous pressure to maintain effective cardiac output. ⋯ This review delineates the essential physiological adaptations during pregnancy and the challenges faced by Fontan patients, advocating for a comprehensive care approach involving multidisciplinary collaboration, vigilant monitoring, tailored anesthetic management, and postpartum care. Understanding the complex dynamics between Fontan physiology and pregnancy is crucial for anesthesiologists to develop and execute individualized management strategies to minimize risks and optimize outcomes for this high-risk population.
