Frailty is a syndrome of cumulative decline across multiple physiological systems, which predisposes vulnerable adults to adverse events. Assessing vulnerable patients can potentially lead to interventions that improve surgical outcomes. ⋯ Radiological modalities, such as computed tomography and ultrasonography, are widely performed before surgery, and are therefore available to be used opportunistically to objectively evaluate surrogate markers of frailty. This review presents the importance of frailty assessment by anaesthesiologists; lists common clinical tools that have been applied; and proposes that utilising radiological imaging as an objective surrogate measure of frailty is a novel, expanding approach for which anaesthesiologists can significantly contribute to broad implementation.

Neuromuscular blocking agents (NMBAs) remain the leading cause of perioperative anaphylaxis in Australia. Standard evaluation comprises history, skin tests, and in vitro specific immunoglobulin E tests. Drug provocation tests to suspected NMBA culprits are associated with a significant risk. Basophil activation testing (BAT) is a potentially useful in vitro test that is not commercially available in Australia or as part of standard evaluation. ⋯ BAT may be a useful supplement to the standard evaluation in diagnosing NMBA anaphylaxis in patients with suggestive histories, but no sensitisation on skin tests. Ongoing study of this specific group of patients is required to clarify its utility in clinical practice.
