Needle in a haystack: localising the long-term neuronal changes from early-life exposure to general anaesthesia.
Narrowing down the histopathological changes in the brain after early-life exposure to general anaesthesia has presented a consistent challenge for preclinical models of anaesthetic neurotoxicity. Using resting-state functional magnetic resonance imaging, in this issue of the journal Neudecker and colleagues demonstrated in vivo connectivity changes in the brain following a seed-based analysis that was derived from previously reported histopathology in the same animals. The combination of neurohistology and neuroimaging should help focus future preclinical studies investigating the developmental consequences of early exposure to general anaesthesia.

Surgical stabilization of rib fractures (SSRF) has become an increasingly common management strategy for traumatic rib fractures. Although historically managed with supportive care, patients with multiple rib fractures and flail chest increasingly undergo SSRF, and so the anesthesiologist must be well-versed in the perioperative management and pain control for these patients, as controlling pain in this population is associated with decreased length of stay and improved outcomes. ⋯ We describe an approach to the assessment of high-risk patients, analgesic and anesthetic techniques including emerging techniques within locoregional anesthesia, ventilation strategies, and potential complications. This review also identifies areas where additional research is needed to ensure optimal anesthetic management for patients undergoing SSRF.

ReviewHypothermic Circulatory Arrest in Adult Aortic Arch Surgery: A Review of Hypothermic Circulatory Arrest and its Anesthetic Implications.
Diseases affecting the aortic arch often require surgical intervention. Hypothermic circulatory arrest (HCA) enables a safe approach during open aortic arch surgeries. Additionally, HCA provides neuroprotection by reducing cerebral metabolism and oxygen requirements. However, HCA comes with significant risks (eg, neurologic dysfunction, stroke, and coagulopathy), and the cardiac anesthesiologist must completely understand the surgical techniques, possible complications, and management strategies.

Observational StudyThe eXpectations of Parents regarding Anesthesiology Study (XPAS) from a parental perspective: a two-phase observational cross-sectional cohort study.
Uncertainty concerning anesthetic procedures and risks in children requiring anesthesia may cause concerns in parents and caregivers. ⋯ Overall, parental satisfaction scores regarding the pediatric anesthesiology procedure were high, with a minority expressing concerns. Parents indicated a preference for their child's anesthesiologist to visit them both before and after the anesthetic procedure. Parental expectations regarding anesthesia did not completely correspond with the information provided; more information from the clinician about the intended effects and side effects of anesthesia was desired.

Identification of interfascial plane using injection pressure monitoring at the needle tip during ultrasound-guided TAP block in cadavers.
Consistency in needle tip positioning within interfascial planes while performing infiltrative blocks under ultrasound guidance can be difficult. The exact determination of such planes may beyond the physical limits of common ultrasound machines. Aim of this pilot study was to understand if real-time continuous injection pressure monitoring at the needle tip, combined with ultrasound guidance, can help to immediately and consistently identify an interfascial plane needle tip placement. ⋯ The identified injection pressure pattern, together with ultrasound image, may help in determine real-time the needle tip position, while performing a TAP block.
