Objective: Critically ill patients suffer disrupted sleep. Hypnotic medications may improve sleep; however, local epidemiological data regarding the amount of nocturnal time awake and the use of such medications is needed.
Design: Point prevalence study.
Objectives: The most efficient way to adjust skeletal muscle area (SMA) derived from chest CT to body size remains unclear. We hypothesized that vertebral body area (VBA) measurement would allow such efficient adjustment.
Methods: We conducted a retrospective observational study of chest CT imaging in a cohort of critically ill COVID-19 patients.
To quantify current protein prescription and delivery in critically ill adults in Australia and New Zealand and compare it with international guidelines. Prospective, multicentre, observational study. Five intensive care units (ICUs) across Australia and New Zealand.

The objective of this study is to understand resuscitation practices in patients presenting to ED with early sepsis.
Methods: Design, participants and setting: Prospective, observational, multicentre, single-day, point-prevalence study enrolling adult patients present in 51 Australian and New Zealand ICUs at 10.
Introduction: Blood pressure (BP) management is common in patients with aneurysmal subarachnoid hemorrhage (SAH) admitted to an intensive care unit. However, the practice patterns of BP management (timing, dose, and duration) have not been studied locally.
Methods: This post hoc analysis explored BP management goals (defined as the setting of a minimum systolic BP target or application of induced hypertension) in patients enrolled into the PROMOTE-SAH study in eleven neurosurgical centers in Australia and New Zealand.
Background: Hypovitamin B1 occurs frequently during critical illness but is challenging to predict or rapidly diagnose. The aim of this study was to evaluate whether plasma phosphate concentrations predict hypovitamin B1, enteral nutrition prevents hypovitamin B1 and intravenous thiamine supplementation achieves supraphysiological concentrations in critically ill patients.
Methods: Thirty-two enterally fed critically ill patients, with a plasma phosphate concentration ≤0.
Objective: To evaluate the association between time from ED presentation to intensive care unit (ICU) transfer on mortality in patients presenting with septic shock.
Methods: Adult patients with suspected septic shock enrolled in the Australasian Resuscitation in Sepsis Evaluation trial were included. The primary outcome of this post-hoc analysis was 90-day mortality.
Our objective was to describe antiseizure medication (ASM) prescription patterns, and associations between ASM use and death and disability outcomes in patients with aneurysmal subarachnoid haemorrhage (aSAH) admitted to ICU. This was a multi-centre prospective observational study. The study took place in eleven ICUs across Australia and New Zealand.

To evaluate the effects of a "liberal" approach to targeted blood glucose range during ICU admission. This mutlicenter, parallel-group, open-label randomized clinical trial included 419 adult patients with type 2 diabetes expected to be in the ICU on at least three consecutive days.

Objective: To determine the relationship between arterial and venous acid-base status in a model of septic shock.
Methods: Paired samples (n = 435) of arterial and femoral venous blood from 57 sheep (47 septic, 10 non-septic) managed with protocol-guided ventilation, sedation, parenteral fluids and inotropic support.
Results: The arterial-venous difference in acid-base parameters was similar with and without sepsis.
Aim: The aim of this study was to investigate the association of hyperoncotic (20%) human albumin solution (HAS) with outcomes among critically ill patients receiving continuous renal replacement therapy (RRT).
Methods: Analysis of the Randomized Evaluation of Normal versus Augmented Level (RENAL) RRT trial data.
Results: Of 1,508 patients, 771 (51%) received albumin.
Background: Frailty is independently associated with morbidity and mortality in critically ill patients. However, the association between preadmission frailty and the degree of treatment received in the intensive care unit (ICU) remains unclear.
Objective: To describe patient length of stay in an ICU and the treatments provided according to the extent of patient frailty.
Background: Hypophosphatemia may be a useful biomarker to identify thiamine deficiency in critically ill enterally-fed patients. The objective was to determine whether intravenous thiamine affects blood lactate, biochemical and clinical outcomes in this group.
Method: This randomized clinical trial was conducted across 5 Intensive Care Units.
Background: Disability is common following critical illness, impacting the quality of life of survivors, and is difficult to measure. 'Participation' can be quantified as involvement in life outside of their home requiring movement from their home to other locations. Participation restriction is a key element of disability, and following critical illness, participation may be diminished.

Design: Prospective cohort study.
Setting: Eleven ICUs in Australia and New Zealand.
Objective: Intravenous antimicrobial therapy within 1 h of the diagnosis of septic shock is recommended in international sepsis guidelines. We aimed to evaluate the association between antimicrobial timing and mortality in patients presenting to the ED with septic shock.
Methods: Post-hoc analysis of 1587 adult participants enrolled in the Australasian Resuscitation in Sepsis Evaluation (ARISE) multicentre trial of early goal-directed therapy for whom the time of initial antimicrobial therapy was recorded.
Self-harm is one of the most common reasons for admission to an intensive care unit (ICU). While most patients with self-harm survive the ICU admission, little is known about their outcomes after hospital discharge. We conducted a retrospective cohort study of patients in the Barwon region in Victoria admitted to the ICU with self-harm (between 1998 and 2018) who survived to hospital discharge.

Materials And Methods: In 12 critically ill patients: oxygen-sensing probe inserted in the bladder catheter and dexmedetomidine infusion at a mean (SD) rate of 0.9 ± 0.
