Effect of On-Demand vs Routine Nebulization of Acetylcysteine With Salbutamol on Ventilator-Free Days in Intensive Care Unit Patients Receiving Invasive Ventilation: A Randomized Clinical Trial

This research by van Meenen and colleagues was published in JAMA March 2018 volume 319 issue 10.
Importance:  It remains uncertain whether nebulization of mucolytics with bronchodilators should be applied for clinical indication or preventively in intensive care unit (ICU) patients receiving invasive ventilation.
Objective:  To determine if a strategy that uses nebulization for clinical indication (on-demand) is non-inferior to one that uses preventive (routine) nebulization.
Design, Setting, and Participants:  Randomized clinical trial enrolling adult patients expected to need invasive ventilation for more than 24 hours at 7 ICUs in the Netherlands.
Interventions:  On-demand nebulization of acetylcysteine or salbutamol (based on strict clinical indications, n = 471) or routine nebulization of acetylcysteine with salbutamol (every 6 hours until end of invasive ventilation, n = 473).
Main Outcomes and Measures:  The primary outcome was the number of ventilator-free days at day 28, with a non-inferiority margin for a difference between groups of -0.5 days. Secondary outcomes included length of stay, mortality rates, occurrence of pulmonary complications, and adverse events.
Results:  Nine hundred twenty-two patients (34% women; median age, 66 (interquartile range [IQR], 54-75 years) were enrolled and completed follow-up. At 28 days, patients in the on-demand group had a median 21 (IQR, 0-26) ventilator-free days, and patients in the routine group had a median 20 (IQR, 0-26) ventilator-free days (1-sided 95% CI, -0.00003 to ∞). There was no significant difference in length of stay or mortality, or in the proportion of patients developing pulmonary complications, between the 2 groups. Adverse events (13.8% vs 29.3%; difference, -15.5% [95% CI, -20.7% to -10.3%]; P #

Implementation of an Evidence-Based Practice Nursing Handover Tool in Intensive Care Using the Knowledge-to-Action Framework

This article in the March 2018 issue of “Worldviews on Evidence Based Nursing” is by Spooner and colleagues.
Background:  Miscommunication during handover has been linked to adverse patient events and is an international patient safety priority. Despite the development of handover resources, standardized handover tools for nursing team leaders (TLs) in intensive care are limited.
Aims:  The study aim was to implement and evaluate an evidence-based electronic minimum data set for nursing TL shift-to-shift handover in the intensive care unit using the knowledge-to-action (KTA) framework.
Methods:  This study was conducted in a 21-bed medical-surgical intensive care unit in Queensland, Australia. Senior registered nurses involved in TL handover were recruited. Three phases of the KTA framework (select, tailor, and implement interventions; monitor knowledge use; and evaluate outcomes) guided the implementation and evaluation process. A post-implementation practice audit and survey were carried out to determine nursing TL use and perceptions of the electronic minimum data set 3 months after implementation. Results are presented using descriptive statistics (median, IQR, frequency, and percentage).
Results:  Overall (86%, n = 49), TLs’ use of the electronic minimum data set for handover and communication regarding patient plan increased. Key content items, however, were absent from handovers and additional documentation was required alongside the minimum data set to conduct handover. Of the TLs surveyed (n = 35), those receiving handover perceived the electronic minimum data set more positively than TLs giving handover (n = 35). Benefits to using the electronic minimum data set included the patient content (48%), suitability for short-stay patients (16%), decreased time updating (12%), and printing the tool (12%). Almost half of the participants, however, found the minimum data set contained irrelevant information, reported difficulties navigating and locating relevant information, and pertinent information was missing. Suggestions for improvement focused on modifications to the electronic handover interface.
Linking Evidence to Action:  Prior to developing and implementing electronic handover tools, adequate infrastructure is required to support knowledge translation and to ensure clinician and organizational needs are met.

Electrodermal Activity during Blood Pooling for Arterial Blood Gases Analysis in Sedated Adult Intensive Care Unit Patients

This article by Aslanidis et al was published in Medical Sciences March 2018 Volume 6 Number 1.
Electrodermal activity (EDA) is considered a measure of autonomous nervous system activity. This study performed an exploratory analysis of the EDA changes during blood pooling for arterial blood gas analysis in sedated adult critical care patients and correlated the variations to other monitored parameters. EDA, along with other parameters, were monitored during 4 h routine daytime intensive care nursing and treatment in an adult ICU. 4 h measurements were divided into two groups based upon the sedation level. Selected recordings before and after blood pooling for arterial blood gases analysis (stress event) was performed. Nine stress events from Group A and 17 from Group B were included for further analysis. Patients’ demographics, laboratory exams, and severity scores were recorded. For both sedation levels, EDA changes are much greater than any other monitoring parameters used. The changes are noticed in both measurement (15 s and 60 s), even though in the 60 s measurement only selected EDA parameters are significantly changed after the start of the procedure. EDA measurements are more sensitive to a given stress event than cardiovascular or respiratory parameters. However, the present results could only be considered as a pilot study. More studies are needed in order to identify the real stress-load and clinical significance of such stimuli, which are considered otherwise painless in those patients.

Fluid accumulation during acute kidney injury in the intensive care unit

This research was published in Acta Anaesthesiologica Scandinavica in March 2018 by Berthelsen et al.
Introduction:  Fluid therapy is a ubiquitous intervention in patients admitted to the intensive care unit, but positive fluid balance may be associated with poor outcomes and particular in patients with acute kidney injury. Studies describing this have defined fluid overload either at specific time points or considered patients with a positive mean daily fluid balance as fluid overloaded. We wished to detail this further and performed joint model analyses of the association between daily fluid balance and outcome represented by mortality and renal recovery in patients admitted with acute kidney injury.
Method:  We did a retrospective cohort study of patients admitted to the intensive care unit with acute kidney injury during a 2-year observation period. We used serum creatinine measurements to identify patients with acute kidney injury and collected sequential daily fluid balance during the first 5 days of admission to the intensive care unit. We used joint modelling techniques to correlate the development of fluid overload with survival and renal recovery adjusted for age, gender and disease severity.
Results:  The cohort contained 863 patients with acute kidney injury of whom 460 (53%) and 254 (29%) developed 5% and 10% fluid overload, respectively. We found that both 5% and 10% fluid overload was correlated with reduced survival and renal recovery.
Conclusion:  Joint model analyses of fluid accumulation in patients admitted to the intensive care unit with acute kidney injury confirm that even a modest degree of fluid overload (5%) may be negatively associated with both survival and renal recovery.
