Anaesthesia and intensive care
-
Patients who come to the intensive care unit are amongst the sickest patients in our hospitals. Patients can be admitted to the intensive care unit unexpectedly (following accidents or sudden onset of illness) or as unplanned but not necessarily truly 'unexpected' admissions. These patients often have significant underlying chronic health issues, including metastatic cancer, advanced cardiac, respiratory, renal, or hepatic failure, or frailty, with a high likelihood of death in the ensuing months. ⋯ First, systematically target 'high risk of dying' patient groups for goals of care conversations in the outpatient setting. Such groups include those where one would not be 'surprised' if they died within a year. Second, as a society, more conversations about end-of-life wishes are needed.

Proceedings of the 12th International Conference on Rapid Response Systems and Medical Emergency Teams.
Rapid Response Teams (RRTs) have been introduced into hospitals worldwide in an effort to improve the outcomes of deteriorating hospitalised patients. Recently, there has been increased awareness of the need to develop systems other than RRTs for deteriorating patients. ⋯ The conference program included broad ranging presentations related to general clinical deterioration in the acute care setting, as well as deterioration in the emergency department, during pregnancy, in the paediatric setting, and deterioration in mental health status. This article briefly summarises the key features of the conference, links to presentations, and the 18 abstracts of the accepted free papers.

Rational Clinical Pathology Assessment in the Intensive Care Unit.
Blood tests are ordered on a daily basis in intensive care units (ICU). There are no widely accepted guidelines for testing requirements. This study investigated the impact on ICU laboratory test costs of a multi-strategy change in practice involving routine blood testing. ⋯ Two protocol-related adverse events were recorded and judged as minor and were resolved by ordering tests during the day. No adverse patient outcomes resulted from these two events. Blood testing authorisation by an ICU specialist was associated with significant cost savings in ICU and no adverse patient outcomes.

Intravascular catheters-an ultrasound imaging based observational study of position and function.
Peripheral intravenous and intra-arterial catheters often block with movement of the limb in which they are inserted. Although the cause of this blockage is commonly attributed to a valve or other structure within the vein, evidence for this is lacking. We used ultrasound to assess the cause of blockage on movement, and degree of tip movement, of 62 venous and 21 radial arterial catheters. ⋯ Mean potential tip movement was 12.3 mm and 5.7 mm in hand and forearm venous catheters respectively and 9.5 mm in radial artery catheters. There was a significantly lower rate of blockage for forearm (20%) compared to dorsal hand venous catheters (83%, P <0.001) and 52% of radial artery catheters showed damping and blockage on wrist flexion. This study emphasises the advantages of placement of venous catheters in the straight veins of the forearm.
