Article Synopsis
  • Critically ill patients with bloodstream infections (BSIs) who experience hypothermia are at a higher risk of death, but the impact of rewarming rates on their outcomes is not well understood.
  • In a study involving 3951 ICU admissions, researchers found that 8.4% of hypothermic patients had temperatures below 34.9°C, and lower temperatures were linked to higher severity of illness and a greater need for organ support.
  • The 90-day case-fatality rate was 22.9% overall, with significantly higher rates among those with lower temperatures; faster rewarming was associated with lower mortality rates even after accounting for illness severity and comorbidities.

Article Synopsis
  • Doctors studied how hydrocortisone, a medicine, is used for patients with septic shock in 12 hospitals to see if its use changed after a big research trial called the ADRENAL trial.
  • They found that more patients started getting hydrocortisone after the trial was published, showing an increase from 28% to 43% over time.
  • The study showed that the change in how often hydrocortisone was given was significant during two different time periods: right after the trial was published and the transition period before that.

Article Synopsis
  • Researchers conducted a multicenter study to compare point-of-care testing (POCT) and central laboratory testing for creatinine measurement in critically ill patients.
  • The study analyzed 79,767 paired creatinine measurements from 19,118 patients in intensive care units, finding that results from POCT were clinically equivalent to central laboratory results.
  • This suggests that POCT could be a viable option for more frequent kidney function monitoring, potentially allowing for earlier detection of acute kidney injury in critically ill patients.

  • The study compared the prevalence and outcomes of sepsis-associated acute kidney injury (SA-AKI) in patients with chronic kidney disease (CKD) versus those without.
  • Among 84,240 ICU admissions, 8.6% involved CKD patients, who had a higher incidence of SA-AKI (21% vs 14%) and were generally older and sicker.
  • Despite worse initial outcomes and higher unadjusted mortality in CKD patients, adjustments showed CKD was not an independent risk factor for increased 90-day mortality or major adverse kidney events.

  • Hypophosphatemia is frequently observed in critically ill patients admitted to Intensive Care Units (ICUs), with a study examining its prevalence and outcomes in Queensland, Australia between 2015 and 2021.
  • Out of 89,776 patients, 68,699 were included, and 34.2% experienced hypophosphatemia, typically identified on the second day of ICU stay and resolved within three days.
  • The severity of hypophosphatemia correlated with increased 90-day mortality rates, with moderate and severe cases showing significantly higher fatality risks compared to those without hypophosphatemia.

Introduction: Traumatic brain injury (TBI) is a heterogeneous condition with a broad spectrum of injury severity, pathophysiological processes and variable outcomes. For moderate-to-severe TBI survivors, recovery is often protracted and outcomes can range from total dependence to full recovery. Despite advances in medical treatment options, prognosis remains largely unchanged.

Background: Handgrip strength (HGS), lung function and health-related quality of life (HRQoL) are relevant indicators of future cardiovascular risk and mortality. The impact of cardiac surgery on these predictive variables has been under-explored. The aim of this study was to determine the acute (within hospital) changes in HGS, lung function and HRQoL, and their relationships, in adults undergoing elective cardiac surgery.

There is substantial interest by clinicians to improve the health outcomes of older and frail patients following major surgery, with prehabilitation a potential and important component of future standard patient care. We studied the feasibility of a randomised controlled trial of pre-operative prehabilitation in frail patients scheduled for colorectal surgery in regional Australia. We conducted a single blind, parallel arm, randomised controlled trial in a regional referral centre where colorectal surgical patients aged over 50 were invited to participate and screened for frailty.

Background: High-risk patients presenting for surgery require complex decision-making and perioperative management. However, given there is no gold standard for identifying high-risk patients, doing so may be challenging for clinicians in practice. Before a gold standard can be established, the state of current practice must be determined.

The Cook staged extubation set (Cook Medical) has been developed to facilitate management of the difficult airway. A guidewire inserted before tracheal extubation provides access to the subglottic airway should re-intubation be required. This prospective cohort study examines patients' tolerance of the guidewire and its impact on clinical status around tracheal extubation in the intensive care unit.

Introduction: Patients who are frail, have multiple comorbidities or have a terminal illness often have poor outcomes from surgery. However, sole specialists may recommend surgery in these patients without consultation with other treating clinicians or allowing for patient goals. The Patient-Centred Advanced Care Planning (PC-ACP) model of care provides a framework in which a multidisciplinary advanced care plan is devised to incorporate high-risk patients' values and goals.

Management of the difficult airway is an important, but as yet poorly-studied, component of intensive care management. Although there has been a strong emphasis on prediction and intubation of the difficult airway, safe extubation of the patient with a potentially difficult airway has not received the same attention. Extubation is a particularly vulnerable time for the critically ill patient and, because of the risks involved and the consequences of failure, it warrants specific consideration.

In this article, we report two cases of acute toxic leukoencephalopathy to highlight this acute clinicoradiological syndrome as an important, although uncommon, consideration in the undifferentiated comatose patient who fails to wake following drug overdose or has unexplained neurology with a history of drug exposure. We then review the current literature and discuss potential differential diagnoses in this setting, along with proposed treatments for this condition. The cases presented demonstrate a more fulminant onset than previously well-defined acute toxic leukoencephalopathy subtypes and highlight the prognostic importance of magnetic resonance imaging in diagnosing a condition from which significant functional recovery seems possible.
