Michael Barbato, Greg Barclay, Jan Potter, Wilf Yeo, Joseph Chung
CONTEXT: When palliative care patients enter the phase of unconsciousness preceding death it is standard practice to initiate or continue a subcutaneous infusion of an opioid plus or minus a sedative. The doses are determined somewhat empirically and adjustments are based on clinical assessment and observational measures of sedation and comfort. Following reports that these observational measures could be misleading, this study assesses their validity by comparing them with an objective measure of sedation, the Bispectral Index score (BIS)...

BACKGROUND: Targeted light sedation is recommended because it shortens the time of mechanical ventilation and the length of stay in an intensive care unit (ICU). However, there is no validated scale for sedation and agitation in ICU in the Serbian speaking area. The aim of the current study was to validate, verify the reliability and enable the application of the Richmond Agitation and Sedation Scale (RASS) in the Serbian speaking area. METHODS: In this prospective cohort study, RASS was applied to 301 adult patients hospitalized in surgical ICUs by two different research team members...

BACKGROUND: The Richmond Agitation-Sedation Scale (RASS) is a single tool that is intuitive, is easy to use, and includes both agitation and sedation. The RASS has never been formally validated for pediatric populations. The objective of this study was to assess inter-rater agreement and criterion validity of the RASS in critically ill children. METHODS: To evaluate validity, the RASS score was compared to both a visual analog scale (VAS) scored by the patient's nurse, and the University of Michigan Sedation Scale (UMSS), performed by a researcher...

Pain is a common and undertreated problem in critically ill patients. Pain assessment in critically ill patients is challenging and relies on complex scoring systems. The aim of this work was to find out the possible role of the perfusion index (PI) measured by a pulse oximeter (Masimo Radical 7; Masimo Corp., Irvine, CA, USA) in pain assessment in critically ill patients. A prospective observational study was carried out on 87 sedated non-intubated patients in a surgical intensive care unit. In addition to routine monitoring, a Masimo pulse oximeter probe was used for PI measurement...

BACKGROUND: Postoperative impairment of the cerebral function can appear immediately after general anesthesia and may be predictive for a postoperative delirium. We compared three tools assessing patients on recovery room admission in order to detect early signs of postoperative brain dysfunction: the Postanesthetic Recovery Score (PARS), the Richmond Agitation-Sedation Scale (RASS) and the Nursing Delirium Screening Scale (Nu-DESC). METHODS: Inclusion criteria of this secondary analysis of the randomized SuDoCo trial were: age ≥60 years, schedule for elective non-cardiac surgery with an anticipated duration of ≥60 minutes, general anesthesia, ability to communicate in German language...

BACKGROUND: Patients receiving therapeutic paralysis may experience inadequate sedation due to intrinsic limitations of behavioral sedation assessment. Bispectral index (BIS™) provides an objective measure of sedation; however, the role of BIS™ is not well defined in intensive care unit (ICU) patients on neuromuscular blocking agents (NMBA). OBJECTIVE: The aim of this study was to delineate the relationship between BIS™ and level of sedation for critically ill patients during therapeutic paralysis...

BACKGROUND: Mammographic density is a well-established risk factor for breast cancer. We investigated the association between three different methods of measuring density or parenchymal pattern/texture on digitized film-based mammograms, and examined to what extent textural features independently and jointly with density can improve the ability to identify screening women at increased risk of breast cancer. METHODS: The study included 121 cases and 259 age- and time matched controls based on a cohort of 14,736 women with negative screening mammograms from a population-based screening programme in Denmark in 2007 (followed until 31 December 2010)...

OBJECTIVES: Delirium disproportionately affects patients with dementia and is associated with adverse outcomes. The diagnosis of delirium superimposed on dementia (DSD), however, can be challenging due to several factors, including the absence of caregivers or the severity of preexisting cognitive impairment. Altered level of consciousness has been advocated as a possible useful indicator of delirium in this population. Here we evaluated the performance of the Richmond Agitation and Sedation Scale (RASS) and the modified-RASS (m-RASS), an ultra-brief measure of the level of consciousness, in the diagnosis of DSD...

BACKGROUND: Variability in sedation may increase the incidence of delirium and mortality, as well as increased intensive care unit (ICU) and hospital lengths of stay (LOS), despite mean Richmond Agitation Sedation Scale (RASS) scores at goal. Coefficient of variation (CV) can be used to represent variability with a higher ratio indicating increased variability. STUDY QUESTION: Do patients with an increased variability in sedation, as evaluated by CV in RASS, have an increased incidence of delirium? METHODS: We conducted a retrospective chart review of adult medical ICU patients requiring mechanical ventilation (MV) for ≥24 hours between January and April 2013...

Use of ketamine in patients requiring extracorporeal membrane oxygenation (ECMO) has rarely been reported, and the optimal dosing strategy remains unclear. A patient admitted with hypoxic respiratory failure required ECMO in addition to continuous infusion of low-dose ketamine following titration of opioid and sedative medications to high doses. After initiation of ketamine, infusion rates of opioids and/or sedatives were maintained or decreased. Recorded Richmond Agitation-Sedation Scale (RASS) scores were -4 to -5 and documented pain scores were 0...

BACKGROUND: Mechanical ventilation is one of the supporting treatments that are used for different reasons. To reduce patients' inconvenience caused due to using tracheal tube and ventilator, sedation is routinely used. Using scales for the sedation, for example, Richmond Agitation Sedation Scale (RASS), may reduce dose of sedation and length of mechanical ventilation. MATERIALS AND METHODS: This study is a randomized clinical trial on 64 patients selected from three intensive care units (ICUs) in Isfahan, Iran...
