Background: Central Line Associated Blood Stream Infections (CLABSI) are significant complications for hospitalized patients. Several different approaches have been used to reduce CLABSI.
Objective: This study aimed to (1) describe a systematic approach used to analyze and reduce CLABSI rates in a surgical ICU (SICU) at a quaternary care medical facility (CLABSI reduction bundle) and (2) examine the association of the bundle on CLABSI rates in the SICU, compared to six unexposed health system ICUs.
Methods: Retrospective analysis of 14,022 adult patients with > 0 central line days within a single health system in the southeastern United States. The CLABSI intervention bundle was created and implemented in July 2021. Single and multiple interrupted time series analyses were performed to assess the impact of the CLABSI bundle on CLABSI rate in SICU (compared to control ICUs) pre- and post-intervention. Secondary analyses examined the association of the bundle with ICU mortality and length of stay.
Results: The CLABSI bundle was associated with a significant immediate effect in reducing the CLABSI rate in the SICU compared with control ICUs. There was no significant change in the slope of CLABSI rate post-intervention, compared to control ICUs. There was no significant association of the CLABSI reduction bundle on ICU length of stay or mortality in the SICU.
Conclusion: The CLABSI bundle was associated with an immediate reduction in CLABSI incidence in the SICU compared to unexposed ICUs. A simple, bundled intervention can be effective in reducing CLABSI incidence in a surgical ICU population.

Influence of liberal versus conservative oxygen therapies on the hemodynamic parameters of mechanically ventilated patients with sepsis: a randomized clinical trial.

Background: There is no significant evidence verifying the efficacy of liberal versus conservative oxygen therapy on hemodynamics in patients with sepsis. We investigated how liberal and conservative oxygen therapy influenced stroke volume, cardiac output, and vasopressor needs in patients with sepsis undergoing mechanical ventilation.
Methods: This randomized clinical trial included 106 patients with an admission diagnosis of infection, a Sequential Organ Failure Assessment (SOFA) score of two points or higher and required invasive mechanical ventilation for at least 72 h.
Introduction: Advanced airway management and ventilation of trauma patients are often needed during acute stabilization and resuscitation and later, in those admitted. In addition to endotracheal intubation for advanced airway management, tracheostomy is commonly used in critically ill patients when prolonged mechanical ventilation is required. However, the outcomes associated with airway management approaches and the timing of a tracheostomy in critically ill patients are mixed.

Background And Aims: Tailoring nutrition to measured energy expenditure (EE) and provision of adequate protein amounts, is considered gold standard for critically ill patients. There are currently no recommendations to measure specific substrate utilization or to adapt nutrition accordingly.
Methods: In this retrospective longitudinal study, we analyzed results of 316 simultaneous measurements of indirect calorimetry (IC) and urinary urea nitrogen (UUN) in 191 mechanically ventilated, critically ill patients, admitted to the surgical intensive care unit (SICU) in a tertiary medical center.

Article Synopsis
- - Hemorrhage is the main cause of preventable death in trauma situations, leading to military and civilian advancements in medical practices, particularly through the use of tourniquets to manage extremity bleeding and save lives.
- - While tourniquets have significantly decreased deaths from bleeding in military settings, noncompressible hemorrhage still poses a major risk, especially before patients receive definitive medical care.
- - The study explores using a small, disposable pressure monitor during resuscitative endovascular balloon occlusion of the aorta (REBOA) to enhance blood pressure monitoring, facilitate better resuscitation practices, and reduce the need for blood products in extreme environments.
