Background: There are limited practical advanced life support algorithms to aid teams in the management of cardiac arrest in patients on extracorporeal membrane oxygenation (ECMO).
Methods: In our specialist tertiary referral centre we developed, by iteration, a novel resuscitation algorithm for ECMO emergencies which we validated through simulation and assessment of our multi-disciplinary team. A Mechanical Life Support course was established to provide theoretical and practical education combined with simulation to consolidate knowledge and confidence in algorithm use. We assessed these measures using confidence scoring, a key performance indicator (the time taken to resolve gas line disconnection) and a multiple choice question (MCQ) examination.
Results: Following this intervention the median confidence scores increased from 2 (Interquartile range IQR 2, 3) to 4 (IQR 4, 4) out of maximum 5 ( = 53, < 0.0001). Theoretical knowledge assessed by median MCQ score increased from 8 (6, 9) to 9 (7, 10) out of maximum 11 ( = 53, p0.0001). The use of the ECMO algorithm reduced the time taken by teams in a simulated emergency to identify a gas line disconnection and resolve the problem from median 128 s (65, 180) to 44 s (31, 59) ( = 36, 0.001) and by a mean of 81.5 s (CI 34, 116, = 0.001).
Conclusions: We present an evidence based practical ECMO resuscitation algorithm that provides guidance to clinical teams responding to cardiac arrest in ECMO patients covering both patient and ECMO troubleshooting.

Numerical transport models are important tools for nuclear emergency decision makers in that they rapidly provide early predictions of dispersion of released radionuclides, which is key information to determine adequate emergency protective measures. They can also help us understand and describe environmental processes and can give a comprehensive assessment of transport and transfer of radionuclides in the environment. Transport of radionuclides in air and ocean is affected by a number of different physico-chemical processes.

Executive functions can be classified into processes of inhibition, working memory and shifting, which together support flexible and goal-directed behaviour and are crucial for both current and later-life outcomes. A large body of literature has identified distinct brain regions critical to performing each of these functions. These findings are however predicated on a piecemeal and single-task approach.

Right ventricular injury (RVI) in respiratory failure receiving veno-venous extracorporeal membrane oxygenation (VV ECMO) is associated with significant mortality. A scoping review is necessary to map the current literature and guide future research regarding the definition and management of RVI in patients receiving VV ECMO. We searched for relevant publications on RVI in patients receiving VV ECMO in Medline, EMBASE, and Web of Science.

Muscle cramps, which are frequently encountered in hemodialysis patients, affect individuals bio-psycho-socially, limit their activities of daily living, and reduce their quality of life. In this study, we aimed to evaluate the effects of aromatherapy massage applied in 12 sessions over 4 weeks on cramp frequency, pain severity, and quality of life. The study was conducted as a pretest-posttest, randomized controlled, and single-blinded using a quantitative and qualitative research design.

Smith+Nephew, Watford, Hertfordshire, UK.
Background: Achievement of moisture balance can be a critical factor affecting time to closure of nonhealing wounds, and dry wounds can take much longer to heal than those with high exudate levels. Whether the goal of management is to donate moisture to the wound or control excessive fluid until the cause has been identified and addressed, choice of dressing and other wound management products can affect nursing resources, clinical outcomes, concordance, and quality of life for the patient.
Case Reports: The cases discussed illustrate differences in management approaches for dry and wet wounds and show how clinician support tools (eg, tissue type, infection/inflammation, moisture imbalance, epithelial edge advancement [TIME] clinical decision support tool) can facilitate treatment decisions.
