Practice GuidelineAustralian and New Zealand Anaesthetic Allergy Group/Australian and New Zealand College of Anaesthetists perioperative anaphylaxis management guideline 2022.
Perioperative anaphylaxis is a potentially life-threatening emergency that requires prompt recognition and institution of life-saving therapy. The Australian and New Zealand College of Anaesthetists and Australian and New Zealand Anaesthetic Allergy Group have partnered to develop the anaphylaxis management guideline along with crisis management cards that are recommended for use in suspected anaphylaxis in the perioperative setting. This is the third version of these guidelines with the second version having been published in 2016. This article contains the revised Australian and New Zealand Anaesthetic Allergy Group/Australian and New Zealand College of Anaesthetists perioperative anaphylaxis management guideline, with a brief review of the current evidence for the management of anaphylaxis in the perioperative environment.

Case ReportsA case series of the Royal Perth Hospital cannula-first approach in the 'can't intubate, can't oxygenate' scenario.
At the Royal Perth Hospital, we have been developing and teaching a can't intubate, can't oxygenate (CICO) rescue algorithm for over 19 years, based on live animal simulation. The algorithm involves a 'cannula-first' approach, with jet oxygenation and progression to scalpel techniques if required in a stepwise fashion. There is little reported experience of this approach to the CICO scenario in humans. ⋯ We recommend that institutions teach and practice this approach; we believe it is effective, safe and minimally invasive when undertaken by clinicians who have been trained in it and have immediate access to the requisite equipment. The equipment is low cost, comprising a 14G Insyte cannula, saline, 5 ml syringe and a Rapid-O2. Training can be provided using low-fidelity manikins or part-task trainers.

The influence of needleless connectors and inserted catheters on flow rates through vascular introducer sheaths.
SummaryA vascular introducer sheath is often used for rapid volume replacement. However, common manipulations such as the addition of needleless connectors to infusion ports and the insertion of catheters or other devices through the introducer sheath may impede flow. In this study we utilised a rapid infuser to deliver room-temperature normal saline through two introducer sheath configurations with and without the addition of needleless connectors and the placement of catheters through the introducer sheaths. ⋯ These findings indicated that both needleless connectors and the placement of catheters through vascular introducer sheaths substantially reduced potential flow rates. Even 'large' vascular introducer sheaths capable of delivering high flow rates could be rendered minimally effective for rapid fluid administration when used in this way. Clinicians should consider these impediments to flow when rapid fluid administration is required, and obtain alternative vascular access if necessary.

Simulated impact of lift car sizes on transport of critical care patients: Informing the design of the New Dunedin Hospital.
The New Dunedin Hospital (NDH) is New Zealand's largest health infrastructure build. Here we describe the use of a simple simulation-based hospital design exercise to inform the appropriate lift car size for critical care intrahospital transfers in the NDH. The intensive care unit (ICU) user group tested a series of entries and exits of simulated complex patient transfers in mocked-up lift cars of three different dimensions. ⋯ The resultant clinical recommendations for the dimensions of a critical care lift car surpass current international health architecture guidelines and may help to inform future updates. The NDH project benefited from an objective assessment of risk, in language familiar to clinicians and healthcare architects. The outcome was an upsizing of the two ICU-capable lifts.
