Managing acute alcohol withdrawal in critical care presents a unique challenge to the critical care nurse. The prominence of alcohol use within the Australian community means that many critical care admissions involve acute alcohol withdrawal, an alcohol induced illness, or indeed an unrelated admission with underlying heavy alcohol intake. Current statistics suggest 1 in 5 Australians drink to 'risky' levels each month. ⋯ Contemporary management guidelines for alcohol withdrawal suggest a common framework of first line benzodiazepine usage, with emerging research focusing on adjunctive therapy aimed at reducing benzodiazepine doses, and therefore reducing length of stay in the critical care unit. The controversial therapy of ethanol infusion and common assessment and withdrawal scales are examined in relation to their usefulness in critical care. Alcohol withdrawal management in critical care necessitates careful nursing assessment, including alcohol usage history, delirium management, withdrawal assessment and symptomatic relief using an evidence-based protocol.

Delirium is an acute, reversible and fluctuating central nervous system dysfunction with an organic cause, and is associated with substantial morbidity and mortality. Many recent studies have shown that delirium is highly prevalent in the Intensive Care Unit (ICU) population. Despite its seriousness; delirium in the ICU is under recognized by bedside nurses. ⋯ There was a significant discrepancy between the ICU bedside nurses' assessment of delirium and the independent formal delirium assessment utilizing the CAM-ICU. We concluded that routine bedside nursing patient interaction do not reliably detect delirium in a critically ill patient.

Radial arterial line is required for critically ill patients to provide continuous blood pressure monitoring and arterial blood sampling. A program training experienced ICU nurses to perform radial artery cannulation was introduced in a Melbourne metropolitan ICU to allow early treatment and intervention to be delivered to patients while medical staff attend to more urgent diagnostic care. The aim of this research was to evaluate the effectiveness of the training program for radial artery cannulation in the ICU. ⋯ The findings showed that ICU nurses can safely insert radial arterial lines with improvements recommended.

Described in this study is the case of a 53-year-old woman who developed a life-threatening infection caused by the bacterium Capnocytophaga canimorsus (C. canimorsus), subsequent to being bitten by a dog. The patient presented to an Emergency Department with a 24-h history of diarrhoea and vomiting with dehydration but within 36 h of presentation developed an overwhelming severe sepsis with septic shock, disseminated intravascular coagulation, acute renal failure, metabolic acidosis and threatened acute respiratory failure requiring urgent intensive care intervention. ⋯ C. canimorsus has been reported as a rare cause of severe infection in susceptible individuals; however this case is of particular interest as there were no apparent predisposing factors conferring risk of severe infection. This case also raised significant practice issues for the treating hospital.
