Onishi Y, Murai Y, Nakajima E. Framework to elicit consent from lightly sedated mechanically ventilated intensive care patients in nursing practice. Jpn J Nurs Sci 2024; 21:e12601. [PMID: 38698302 DOI: 10.1111/jjns.12601] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Revised: 03/23/2024] [Accepted: 04/02/2024] [Indexed: 05/05/2024]
Abstract
AIM The study aimed to ascertain a framework of nursing practices to elicit consent from lightly sedated ventilated patients. METHODS Study participants were nurses working in intensive care and critical care wards, whose observations and semi-structured interviews were assessed using a modified grounded theory approach. RESULTS A total of 15 concepts were generated, from which three categories and three subcategories were generated. Category 1: Nurses taking the lead in providing assistance by sharing signs of change while continuing the invasive treatment, working to maintain the patient's life, alleviation of pain, promotion of awareness of the current situation, and acclimating them to the treatment environment as the basis for building a relationship between patients and nurses. Category 2: Searching for points of agreement and reaching a compromise involves the nurse drawing out the patient's thoughts, hopes, and expectations, and transforming the relationship into a patient-centered one by sharing goals with the patient in order to achieve them. Category 3: Organizing collaboration within care supported the patient's ability to move safely while maintaining the patient's pace to achieve shared goals, and guided the patient's independent actions. CONCLUSIONS Even when patients recover from an acute life-threatening situation, their physical sensations remain vague and their functional decline continues. Rather than simply eliciting consent from patients, the structure of nursing practice to elicit such response from patients involves drawing out the patient's thoughts, hopes, and expectations, as well as guiding the patient toward goals that they have created together with the nurse and utilizing the patient's strengths to achieve these goals.

Abstract
BACKGROUND ABC-123, a novel Epic electronic medical record real-time score, assigns 0 to 3 points per bundle element to assess ABCDEF bundle compliance. We sought to determine if maximum daily ABC-123 score (ABC-MAX), individual bundle elements, and mobility were associated with mortality and delirium-free/coma-free intensive care unit (DF/CF-ICU) days in critically injured patients. METHODS We reviewed 6 months of single-center data (demographics, Injury Severity Score [ISS], Abbreviated Injury Scale of the head [AIS-Head] score, ventilator and restraint use, Richmond Agitation Sedation Score, Confusion Assessment Method for the ICU, ABC-MAX, ABC-123 subscores, and mobility level). Hospital mortality and likelihood of DF/CF-ICU days were endpoints for logistic regression with ISS, AIS-Head, surgery, penetrating trauma, sex, age, restraint and ventilator use, ABC-MAX or individual ABC-123 subscores, and mobility level or a binary variable representing any improvement in mobility during admission. RESULTS We reviewed 172 patients (69.8% male; 16.3% penetrating; median age, 50.0 years [IQR, 32.0-64.8 years]; ISS, 17.0 [11.0-26.0]; AIS-Head, 2.0 [0.0-3.0]). Of all patients, 66.9% had delirium, 48.8% were restrained, 51.7% were ventilated, and 11.0% died. Age, ISS, AIS-Head, and penetrating mechanism were associated with increased mortality. Restraints were associated with more than 70% reduction in odds of DF/CF-ICU days. Maximum daily ABC-123 score and mobility level were associated with decreased odds of death and increased odds of DF/CF-ICU days. Any improvement in mobility during hospitalization was associated with an 83% reduction in mortality odds. A and C subscores were associated with increased mortality, and A was also associated with decreased DF/CF-ICU days. B and D subscores were associated with increased DF/CF-ICU days. D and E subscores were associated with decreased mortality. CONCLUSION Maximum daily ABC-123 score is associated with reduced mortality and delirium in critically injured patients, while mobility is associated with dramatic reduction in mortality. B and D subscores have the strongest positive effects on both mortality and delirium. LEVEL OF EVIDENCE Therapeutic/Care Management; Level III.

Abstract
INTRODUCTION Sedation is a cornerstone therapy in the management of patients receiving mechanical ventilation and is highly influential on outcome. Early sedation depth appears especially influential, as early deep sedation is associated with worse outcome when compared with light sedation. Our research group has shown that patients receiving mechanical ventilation in the emergency department (ED) are exposed to deep sedation commonly, and ED sedation depth is impactful on intensive care unit (ICU) care and clinical outcomes. While extensive investigation has occurred for patients in the ICU, comparatively little data exist from the ED. Given the influence that ED sedation seems to carry, as well as a lack of ED-based sedation trials, there is significant rationale to investigate ED-based sedation as a means to improve outcome. METHODS AND ANALYSIS This is a multicentre (n=3) prospective, before-and-after pilot trial examining the feasibility of implementing targeted sedation in the immediate postintubation period in the ED. A cohort of 344 patients receiving mechanical ventilation in ED will be included. Feasibility outcomes include: (1) participant recruitment; (2) proportion of Richmond Agitation-Sedation Scale (RASS) scores in the deep sedation range; (3) reliability (agreement) of RASS measurements performed by bedside ED nurses; and (4) adverse events. The proportion of deep sedation measurements before and after the intervention will be compared using the χ2 test. Logistic regression will be used to compare before-and-after differences, adjusting for potential confounders. The inter-rater correlation coefficient will be used to assess paired observations between a study team member and bedside ED nurses, and to describe reliability of RASS measurements. ETHICS AND DISSEMINATION The Human Research Protection Office at Washington University in St. Louis School of Medicine has approved the study. The publication of peer-reviewed manuscripts and the presentation of abstracts at scientific meetings will be used to disseminate the work.

Sedation Patterns and Hyperosmolar Therapy in Emergency Departments were Associated with Blood Pressure Variability and Outcomes in Patients with Spontaneous Intracranial Hemorrhage. J Emerg Trauma Shock 2020; 13:151-160. [PMID: 33013096 PMCID: PMC7472811 DOI: 10.4103/jets.jets_76_19] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Revised: 11/02/2019] [Accepted: 11/21/2019] [Indexed: 11/04/2022] Open
Abstract
Background Spontaneous intracranial hemorrhage (sICH) is associated with high mortality. Little information exists to guide initial resuscitation in the emergency department (ED) setting. However, blood pressure variability (BPV) and mechanical ventilation (MV) are known risk factors for poor outcome in sICH. Objectives The objective was to examine the associations between BPV and MV in ED (EDMV) and between two ED interventions - post-MV sedation and hyperosmolar therapy for elevated intracranial pressure - and BPV in the ED and in-hospital mortality. Methods We retrospectively studied adults with sICH and external ventricular drainage who were transferred to a quaternary academic medical center from other hospitals between January 2011 and September 2015. We used multivariable linear and logistic regressions to measure associations between clinical factors, BPV, and outcomes. Results We analyzed ED records from 259 patients. There were 143 (55%) EDMV patients who had more severe clinical factors and significantly higher values of all BPV indices than NoEDMV patients. Two clinical factors and none of the severity scores (i.e., Hunt and Hess, World Federation of Neurological Surgeons Grades, ICH score) correlated with BPV. Hyperosmolarity therapy without fluid resuscitation positively correlated with all BPV indices, whereas propofol infusion plus a narcotic negatively correlated with one of them. Two BPV indices, i.e., successive variation of blood pressure (BPSV) and absolute difference in blood pressure between ED triage and departure (BPDepart - Triage), were significantly associated with increased mortality rate. Conclusion Patients receiving MV had significantly higher BPV, perhaps related to disease severity. Good ED sedation, hyperosmolar therapy, and fluid resuscitation were associated with less BPV and lower likelihood of death.

Abstract
OBJECTIVE Patients with spontaneous intracranial hemorrhage (sICH) have poor outcomes, in part because of blood pressure variability (BPV). Patients with sICH causing elevated intracranial pressure (ICP) are frequently transferred to tertiary centers for neurosurgical interventions. We hypothesized that BPV and care intensity during transport would correlate with outcomes in patients with sICH and elevated ICP. METHODS We analyzed charts from adult sICH patients who were transferred from emergency departments to a quaternary academic center from January 1, 2011, to September 30, 2015, and received external ventricular drainage. Outcomes were in-hospital mortality and the Glasgow Coma Scale on day 5 (HD5GCS). Multivariable and ordinal logistic regressions were used for associations between clinical factors and outcomes. RESULTS We analyzed 154 patients, 103 (67%) had subarachnoid hemorrhage and 51 (33%) intraparenchymal hemorrhage; 38 (25%) died. BPV components were similar between survivors and nonsurvivors and not associated with mortality. Each additional intervention during transport was associated with a 5-fold increase in likelihood to achieve a higher HD5GCS (odds ratio = 5.4; 95% confidence interval, 1.7-16; P = .004). CONCLUSION BPV during transport was not associated with mortality. However, high standard deviation in systolic blood pressure during transport was associated with lower HD5GCS in patients with intraparenchymal hemorrhage. Further studies are needed to confirm our observations.

Abstract
INTRODUCTION One major challenge to achieving optimal patient outcome in extracorporeal membrane oxygenation (ECMO) is the development of effective dosing strategies in this critically ill patient population. Suboptimal drug dosing impacts on patient outcome as patients on ECMO often require reversal of the underlying pathology with effective pharmacotherapy in order to be liberated of the life-support device. Areas covered: This article provides a concise review of the effective use of antibiotics, analgesics, and sedative by characterizing the specific changes in PK secondary to the introduction of the ECMO support. We also discuss the barriers to achieving optimal pharmacotherapy in patients on ECMO and also the current and potential research that can be undertaken to address these clinical challenges. Expert opinion: Decreased bioavailability due to sequestration of drugs in the ECMO circuit and ECMO induced PK alterations are both significant barriers to optimal drug dosing. Evidence-based drug choices may minimize sequestration in the circuit and would enable safety and efficacy to be maintained. More work to characterize ECMO related pharmacodynamic alterations such as effects of ECMO on hepatic cytochrome system are still needed. Novel techniques to increase target site concentrations should also be explored.

Abstract
INTRODUCTION Spontaneous intracranial hemorrhage (sICH) that increases intracranial pressure (ICP) is a life-threatening emergency often requiring intubation in Emergency Departments (ED). A previous study of intubated ED patients found that providing ≥5 interventions after initiating mechanical ventilation (pMVI) reduced mortality rate. We hypothesized that pMVIs would lower blood pressure variability (BPV) in patients with sICH and thus improve survival rates and neurologic outcomes. METHOD We performed a retrospective study of adults, who were transferred to a quaternary medical center between 01/01/2011 and 09/30/2015 for sICH, received an extraventricular drain during hospitalization. They were identified by International Classification of Diseases, version 9 (430.XX, 431.XX), and procedure code 02.21. Outcomes were BPV indices, death, and being discharged home. RESULTS We analyzed records from 147 intubated patients transferred from 40 EDs. Forty-one percent of patients received ≥5 pMVIs and was associated with lower median successive variation in systolic blood pressure (BPSV) (31,[IQR 18-45) compared with those receiving 4 or less pMVIs (38[IQR 16-70]], p = 0.040). Three pMVIs, appropriate tidal volume, sedative infusion, and capnography were significantly associated with lower BPV. In addition to clinical factors, BPSV (OR 26; 95% CI 1.2, >100) and chest radiography (OR 0.3; 95% CI 0.09, 0.9) were associated with mortality rate. Use of quantitative capnography (OR 8.3; 95%CI, 4.7, 8.8) was associated with increased likelihood of being discharged home. CONCLUSIONS In addition to disease severity, individual pMVIs were significantly associated with BPV and patient outcomes. Emergency physicians should perform pMVIs more frequently to prevent BPV and improve patients' outcomes.

Abstract
Current guidelines on the management of pain, agitation, and delirium in the intensive care unit (ICU) recommend a non-benzodiazepine (BDZ)–based approach to sedation. Management of agitation can be challenging in multitrauma patients but is imperative to facilitate patient recovery. Given the current guideline recommendations, a protocol to eliminate BDZ administration and maintain light levels of sedation was adopted in our ICU. The purpose of this analysis was to demonstrate that it is feasible to safely eliminate BDZ administration in a trauma ICU. This was a single-center, retrospective, observational analysis at a Level I trauma center. Adult patients (>18 years old) admitted to the Trauma Critical Care service from March 2015 to August 2015 were included. The primary outcome recorded was the use and duration of nonprocedural BDZs which was defined as BDZ not given within one hour of a procedure or test. A total of 64 patients met the inclusion criteria. The average Injury Severity Score was 18.7. A total of 14 patients (21.9%) received BDZ for a nonprocedure-related indication. Of those patients, all (100%) received less than three as-needed doses of BDZs during their ICU stay. In mechanically ventilated patients, continuous sedation or analgesia was not continued for more than 1.3 days. Only five patients (7.8%) received continuous BDZ. Limiting sedation is feasible in critically ill polytrauma patients. Protocols to standardize sedation strategies should be implemented in the ICU to avoid unnecessary sedation.

Abstract
Optimal pharmacological management during extracorporeal membrane oxygenation (ECMO) involves more than administering drugs to reverse underlying disease. ECMO is a complex therapy that should be administered in a goal-directed manner to achieve therapeutic endpoints that allow reversal of disease and ECMO wean, minimisation of complications (treatment of complications when they do occur), early interruption of sedation and rehabilitation, maximising patient comfort and minimising risks of delirium. ECMO can alter both the pharmacokinetics (PK) and pharmacodynamics (PD) of administered drugs and our understanding of these alterations is still evolving. Based on available data it appears that modern ECMO circuitry probably has a less significant impact on PK when compared with critical illness itself. However, these findings need further confirmation in clinical population PK studies and such studies are underway. The altered PD associated with ECMO is less understood and more research is indicated. Until robust dosing guidelines become available, clinicians will have to rely on the principles of drug dosing in critically ill and known PK alterations induced by ECMO itself. This article summarises the PK alterations and makes preliminary recommendations on possible dosing approaches.

Abstract
Patients admitted to the cardiac intensive care unit frequently develop multi-organ system dysfunction associated with their cardiac disease. In many cases, invasive mechanical ventilation is required, which often necessitates sedation for patient-ventilator synchrony, reduction of work of breathing, and patient comfort. In this paper, we describe the use of common sedatives available in the endotracheally intubated critically ill patient and emphasize the clinical and cardiovascular effects. We review γ-aminobutyric acid agonists such as etomidate, benzodiazepines, and propofol, the centrally acting α2-agonist dexmedetomidine, and the N-methyl-D-aspartate receptor antagonist ketamine. Additionally, we outline the use of opioids and their role in potentiating other sedatives. We note that some sedatives are associated with increased delirium rates, and emphasize that judicious strategies minimizing sedative use are associated with decreases in morbidity and mortality. We also discuss standardized sedation assessment scales and highlight the importance of sedation weaning. Finally, we offer recommendations for sedation use during therapeutic hypothermia, and discuss the use of adjuvant neuromuscular blocking agents.

Abstract
[Purpose] The purpose of this study was to investigate the effects of new sedation
management methods and cooperation between nurses and physical therapists on the duration
of mechanical ventilation and hospitalization. [Subjects and Methods] Patients who had
been treated at the study hospital 2 years before and after the implementation of the new
methods were analyzed retrospectively and classified into a “control group” and an
“intervention group”, respectively. Both groups were analyzed and subsequently compared
regarding the effects of the new sedation and cooperative rehabilitation. [Results] A
total of 70 patients met the inclusion criteria and were divided evenly into the two
groups. No significant differences were found between the groups in age, APACHE II score,
or duration of stay in hospital. On the other hand, significant decreases were seen in the
duration of sedation and intubation, mechanical ventilation, and stay in the emergency
ward, as well as time until standing. In addition, after intervention, three patients
undergoing ventilator treatment were able to be ambulated. [Conclusion] These results
suggest that the new sedation and cooperative rehabilitation methods for critically ill
patients were effective in the early stage of treatment and shortened the duration of stay
in the ward.

Abstract
The practice of sedation dosing strategy in mechanically ventilated patient has a profound effect on cognitive function. We conducted a comprehensive review of outcome of sedation on mental health function in critically ill patients on mechanical ventilation in the intensive care unit (ICU). We specifically evaluated current sedative dosing strategy and the development of delirium, post-traumatic stress disorders (PTSDs) and agitation. Based on this review, heavy dosing sedation strategy with benzodiazepines contributes to cognitive dysfunction. However, outcome for mental health dysfunction is mixed in regard to newer sedatives agents such as dexmedetomidine and propofol. Moreover, studies that examine the impact of sedatives for persistence of PTSD/delirium and its long-term cognitive and functional outcomes for post-ICU patients are frequently underpowered. Most studies suffer from low sample sizes and methodological variations. Therefore, larger randomized controlled trials are needed to properly assess the impact of sedation dosing strategy on cognitive function.

Abstract
BACKGROUND Critically ill mechanically ventilated patients in ED have complex needs; chief among these is adequate sedation in addition to effective pain-relief. Emergency nurses are increasingly responsible sedation and analgesia for this complex cohort of patients. The aim of this review was to examine (1) the evidence around assessing, monitoring and managing continuous intravenous sedation for critically ill adult patients, and (2) the implications for emergency nursing practice. STUDY DESIGN Systematic review. METHOD The review of literature extended from 1946 to 2013 and examined peer review journal articles, policy and guidelines to provide a more complex understanding of a phenomenon of concern. A total of 98 articles were incorporated and comprehensively examined. RESULTS Analysis of the literature identified several implications for emergency nursing practice and the management of continuous intravenous sedation: workload, education, monitoring and assessing sedation and policy. CONCLUSION Limited literature was found that directly addressed Australasian emergency nursing practices' in managing on-going intravenous sedation and analgesia for patients. Balancing patient sedation and analgesia requires highly complex knowledge, skills and expertise; the degree of education and training required is above that obtained during pre-registration nurse training. No state or national models of education or training were identified to support ED nurses' practices in managing sedation. Little research has addressed the safety of continuous sedation use in ED.

Abstract
AIM To generate an initial profile of emergency nurses' practices in and factors influencing the assessment and administration of continuous intravenous sedation and analgesia for critically ill mechanically ventilated adult patients. BACKGROUND Emergency nurses are relied upon to assess and manage critically ill patients, some of whom require continuous intravenous sedation. Balancing sedation is a highly complex activity. There is however little evidence relating to how emergency nurses manage continuous intravenous analgesia and sedation for the critically ill intubated patients. DESIGN Descriptive study. METHOD A 12-month retrospective medical record review was undertaken from January to December 2009 of patients (>16 years) administered continuous intravenous sedation in ED. RESULTS Fifty-five patients received ongoing intravenous sedation within the ED during a median length of stay of 3.4 h. Assessment of patient depth/quality of sedation and pain-relief varied and were rarely documented. Adverse events were documented, majority (16%) drug administration related. Thematic analysis identified three themes: 'Maintaining sedation', 'Directionless-directions', and 'Navigating the balance'. CONCLUSION Emergency nurses provide continuity of patient care and optimisation of analgesia and sedation for critically ill sedated patients. The safety and effectiveness of continuous intravenous sedation for the critically ill adult patient in ED are dependent on the expertise and decision-making abilities of the nurse.

Abstract
BACKGROUND Daily sedative interruption and intermittent sedation are effective in abbreviating the time on mechanical ventilation. Whether one is superior to the other has not yet been determined. Our aim was to compare daily interruption and intermittent sedation during the mechanical ventilation period in a low nurse staffing ICU. METHODS Adult patients expected to need mechanical ventilation for more than 24 hours were randomly assigned, in a single center, either to daily interruption of continuous sedative and opioid infusion or to intermittent sedation. In both cases, our goal was to maintain a Sedation Agitation Scale (SAS) level of 3 or 4; that is patients should be calm, easily arousable or awakened with verbal stimuli or gentle shaking. Primary outcome was ventilator-free days in 28 days. Secondary outcomes were ICU and hospital mortality, incidence of delirium, nurse workload, self-extubation and psychological distress six months after ICU discharge. RESULTS A total of 60 patients were included. There were no differences in the ventilator-free days in 28 days between daily interruption and intermittent sedation (median: 24 versus 25 days, P = 0.160). There were also no differences in ICU mortality (40 versus 23.3%, P = 0.165), hospital mortality (43.3 versus 30%, P = 0.284), incidence of delirium (30 versus 40%, P = 0.472), self-extubation (3.3 versus 6.7%, P = 0.514), and psychological stress six months after ICU discharge. Also, the nurse workload was not different between groups, but it was reduced on day 5 compared to day 1 in both groups (Nurse Activity Score (NAS) in the intermittent sedation group was 54 on day 1 versus 39 on day 5, P < 0.001; NAS in daily interruption group was 53 on day 1 versus 38 on day 5, P < 0.001). Fentanyl and midazolam total dosages per patient were higher in the daily interruption group. The tidal volume was higher in the intermittent sedation group during the first five days of ICU stay. CONCLUSIONS There was no difference in the number of ventilator-free days in 28 days between both groups. Intermittent sedation was associated with lower sedative and opioid doses.

Abstract
A prospective observational study was conducted on patients admitted to an adult intensive care unit (ICU) to investigate the pattern of sedation, analgesia and neuromuscular blockade and to determine their relationship to patient outcomes. Data including age, gender, diagnoses, dosage of sedatives, analgesics and neuromuscular blocking agents (NMBA), duration of mechanical ventilation, admission and weaning sedation scores, ICU length of stay and outcomes were recorded; 1550 patient-days were studied from 140 mechanically ventilated patients, of which 52 (37%) received NMBA. The mean length of stay in patients receiving NMBA was 15.6 days compared to 11.7 in patients who did not receive them (p=0.08). Mean duration of mechanical ventilation was 12.5 days in patients receiving NMBA, while it was 10.2 days in patients who did not receive NMBA (p=0.21). Neuromuscular blockade did not significantly influence the duration of mechanical ventilation, length of stay and survival of ICU patients.

Abstract
BACKGROUND Clinical trials exploring optimal sedation management in critically ill pediatric patients are urgently needed to improve both short- and long-term outcomes. Concise operational definitions that define and provide best-available estimates of sedation-related adverse events (AE) in the pediatric population are fundamental to this line of inquiry. OBJECTIVES To perform a multiphase systematic review of the literature to identify, define, and provide estimates of sedation-related AEs in the pediatric ICU setting for use in a multicenter clinical trial. METHODS In Phase One, we identified and operationally defined the AE. OVID-MEDLINE and CINAHL databases were searched from January 1998 to January 2012. Key terms included sedation, intensive and critical care. We limited our search to data-based clinical trials from neonatal to adult age. In Phase Two, we replicated the search strategy for all AEs and identified pediatric-specific AE rates. RESULTS We reviewed 20 articles identifying sedation-related adverse events and 64 articles on the pediatric-specific sedation-related AE. A total of eleven sedation-related AEs were identified, operationally defined and estimated pediatric event rates were derived. AEs included: inadequate sedation management, inadequate pain management, clinically significant iatrogenic withdrawal, unplanned endotracheal tube extubation, post-extubation stridor with chest-wall retractions at rest, extubation failure, unplanned removal of invasive tubes, ventilator-associated pneumonia, catheter-associated bloodstream infection, Stage II+ pressure ulcers and new tracheostomy. CONCLUSIONS Concise operational definitions that defined and provided best-available event rates of sedation-related AEs in the pediatric population are presented. Uniform reporting of adverse events will improve subject and patient safety.

Abstract
The management of pain, agitation, and delirium in critically ill patients can be complicated by multiple factors. Decisions to administer opioids, sedatives, and antipsychotic medications are frequently driven by a desire to facilitate patients' comfort and their tolerance of invasive procedures or other interventions within the ICU. Despite accumulating evidence supporting new strategies to optimize pain, sedation, and delirium practices in the ICU, many critical care practitioners continue to embrace false perceptions regarding appropriate management in these critically ill patients. This article explores these perceptions in more detail and offers new evidence-based strategies to help critical care practitioners better manage sedation and delirium, particularly in ICU patients.

Abstract
Introduction Cardiac troponins are sensitive and specific biomarkers of myocardial necrosis. We evaluated troponin, CK, and ECG abnormalities in patients with septic shock and compared the effect of vasopressin (VP) versus norepinephrine (NE) on troponin, CK, and ECGs. Methods This was a prospective substudy of a randomized trial. Adults with septic shock randomly received, blinded, a low-dose infusion of VP (0.01 to 0.03 U/min) or NE (5 to 15 μg/min) in addition to open-label vasopressors, titrated to maintain a mean blood pressure of 65 to 75 mm Hg. Troponin I/T, CK, and CK-MB were measured, and 12-lead ECGs were recorded before study drug, and 6 hours, 2 days, and 4 days after study-drug initiation. Two physician readers, blinded to patient data and drug, independently interpreted ECGs. Results We enrolled 121 patients (median age, 63.9 years (interquartile range (IQR), 51.1 to 75.3), mean APACHE II 28.6 (SD 7.7)): 65 in the VP group and 56 in the NE group. At the four time points, 26%, 36%, 32%, and 21% of patients had troponin elevations, respectively. Baseline characteristics and outcomes were similar between patients with positive versus negative troponin levels. Troponin and CK levels and rates of ischemic ECG changes were similar in the VP and the NE groups. In multivariable analysis, only APACHE II was associated with 28-day mortality (OR, 1.07; 95% CI, 1.01 to 1.14; P = 0.033). Conclusions Troponin elevation is common in adults with septic shock. We observed no significant differences in troponin, CK, and ECGs in patients treated with vasopressin and norepinephrine. Troponin elevation was not an independent predictor of mortality.

Abstract
A recently proposed interprofessional, evidence-based, multicomponent approach to mitigating the effects of intensive care unit (ICU)-acquired delirium and weakness has the potential to radically transform the way care is delivered to older adults requiring sedation, mechanical ventilation, or both. The Awakening and Breathing Coordination, Delirium Monitoring and Management, and Early Mobility (ABCDE) bundle empowers members of the interdisciplinary ICU team to implement the best available evidence regarding mechanical ventilation, sedation, weakness, and delirium in a safe, effective, and patient-centered manner. Considering that critically ill older adults are cared for in a number of different settings during the course of hospitalization and recovery, the purpose of this article is to explore the rationale and possible benefits of extending the ABCDE bundle into the post-ICU setting. We provide a case study that illustrates how ABCDE bundle adoption could be the key to improving the quality of care provided to seriously ill older adults in the ICU and beyond.

Abstract
OBJECTIVE To provide an update to the "Surviving Sepsis Campaign Guidelines for Management of Severe Sepsis and Septic Shock," last published in 2008. DESIGN A consensus committee of 68 international experts representing 30 international organizations was convened. Nominal groups were assembled at key international meetings (for those committee members attending the conference). A formal conflict of interest policy was developed at the onset of the process and enforced throughout. The entire guidelines process was conducted independent of any industry funding. A stand-alone meeting was held for all subgroup heads, co- and vice-chairs, and selected individuals. Teleconferences and electronic-based discussion among subgroups and among the entire committee served as an integral part of the development. METHODS The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to guide assessment of quality of evidence from high (A) to very low (D) and to determine the strength of recommendations as strong (1) or weak (2). The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. Some recommendations were ungraded (UG). Recommendations were classified into three groups: 1) those directly targeting severe sepsis; 2) those targeting general care of the critically ill patient and considered high priority in severe sepsis; and 3) pediatric considerations. RESULTS Key recommendations and suggestions, listed by category, include: early quantitative resuscitation of the septic patient during the first 6 hrs after recognition (1C); blood cultures before antibiotic therapy (1C); imaging studies performed promptly to confirm a potential source of infection (UG); administration of broad-spectrum antimicrobials therapy within 1 hr of recognition of septic shock (1B) and severe sepsis without septic shock (1C) as the goal of therapy; reassessment of antimicrobial therapy daily for de-escalation, when appropriate (1B); infection source control with attention to the balance of risks and benefits of the chosen method within 12 hrs of diagnosis (1C); initial fluid resuscitation with crystalloid (1B) and consideration of the addition of albumin in patients who continue to require substantial amounts of crystalloid to maintain adequate mean arterial pressure (2C) and the avoidance of hetastarch formulations (1C); initial fluid challenge in patients with sepsis-induced tissue hypoperfusion and suspicion of hypovolemia to achieve a minimum of 30 mL/kg of crystalloids (more rapid administration and greater amounts of fluid may be needed in some patients) (1C); fluid challenge technique continued as long as hemodynamic improvement, as based on either dynamic or static variables (UG); norepinephrine as the first-choice vasopressor to maintain mean arterial pressure ≥ 65 mm Hg (1B); epinephrine when an additional agent is needed to maintain adequate blood pressure (2B); vasopressin (0.03 U/min) can be added to norepinephrine to either raise mean arterial pressure to target or to decrease norepinephrine dose but should not be used as the initial vasopressor (UG); dopamine is not recommended except in highly selected circumstances (2C); dobutamine infusion administered or added to vasopressor in the presence of a) myocardial dysfunction as suggested by elevated cardiac filling pressures and low cardiac output, or b) ongoing signs of hypoperfusion despite achieving adequate intravascular volume and adequate mean arterial pressure (1C); avoiding use of intravenous hydrocortisone in adult septic shock patients if adequate fluid resuscitation and vasopressor therapy are able to restore hemodynamic stability (2C); hemoglobin target of 7-9 g/dL in the absence of tissue hypoperfusion, ischemic coronary artery disease, or acute hemorrhage (1B); low tidal volume (1A) and limitation of inspiratory plateau pressure (1B) for acute respiratory distress syndrome (ARDS); application of at least a minimal amount of positive end-expiratory pressure (PEEP) in ARDS (1B); higher rather than lower level of PEEP for patients with sepsis-induced moderate or severe ARDS (2C); recruitment maneuvers in sepsis patients with severe refractory hypoxemia due to ARDS (2C); prone positioning in sepsis-induced ARDS patients with a PaO2/FIO2 ratio of ≤ 100 mm Hg in facilities that have experience with such practices (2C); head-of-bed elevation in mechanically ventilated patients unless contraindicated (1B); a conservative fluid strategy for patients with established ARDS who do not have evidence of tissue hypoperfusion (1C); protocols for weaning and sedation (1A); minimizing use of either intermittent bolus sedation or continuous infusion sedation targeting specific titration endpoints (1B); avoidance of neuromuscular blockers if possible in the septic patient without ARDS (1C); a short course of neuromuscular blocker (no longer than 48 hrs) for patients with early ARDS and a Pao2/Fio2 < 150 mm Hg (2C); a protocolized approach to blood glucose management commencing insulin dosing when two consecutive blood glucose levels are > 180 mg/dL, targeting an upper blood glucose ≤ 180 mg/dL (1A); equivalency of continuous veno-venous hemofiltration or intermittent hemodialysis (2B); prophylaxis for deep vein thrombosis (1B); use of stress ulcer prophylaxis to prevent upper gastrointestinal bleeding in patients with bleeding risk factors (1B); oral or enteral (if necessary) feedings, as tolerated, rather than either complete fasting or provision of only intravenous glucose within the first 48 hrs after a diagnosis of severe sepsis/septic shock (2C); and addressing goals of care, including treatment plans and end-of-life planning (as appropriate) (1B), as early as feasible, but within 72 hrs of intensive care unit admission (2C). Recommendations specific to pediatric severe sepsis include: therapy with face mask oxygen, high flow nasal cannula oxygen, or nasopharyngeal continuous PEEP in the presence of respiratory distress and hypoxemia (2C), use of physical examination therapeutic endpoints such as capillary refill (2C); for septic shock associated with hypovolemia, the use of crystalloids or albumin to deliver a bolus of 20 mL/kg of crystalloids (or albumin equivalent) over 5 to 10 mins (2C); more common use of inotropes and vasodilators for low cardiac output septic shock associated with elevated systemic vascular resistance (2C); and use of hydrocortisone only in children with suspected or proven "absolute"' adrenal insufficiency (2C). CONCLUSIONS Strong agreement existed among a large cohort of international experts regarding many level 1 recommendations for the best care of patients with severe sepsis. Although a significant number of aspects of care have relatively weak support, evidence-based recommendations regarding the acute management of sepsis and septic shock are the foundation of improved outcomes for this important group of critically ill patients.

Abstract
OBJECTIVE To revise the "Clinical Practice Guidelines for the Sustained Use of Sedatives and Analgesics in the Critically Ill Adult" published in Critical Care Medicine in 2002. METHODS The American College of Critical Care Medicine assembled a 20-person, multidisciplinary, multi-institutional task force with expertise in guideline development, pain, agitation and sedation, delirium management, and associated outcomes in adult critically ill patients. The task force, divided into four subcommittees, collaborated over 6 yr in person, via teleconferences, and via electronic communication. Subcommittees were responsible for developing relevant clinical questions, using the Grading of Recommendations Assessment, Development and Evaluation method (http://www.gradeworkinggroup.org) to review, evaluate, and summarize the literature, and to develop clinical statements (descriptive) and recommendations (actionable). With the help of a professional librarian and Refworks database software, they developed a Web-based electronic database of over 19,000 references extracted from eight clinical search engines, related to pain and analgesia, agitation and sedation, delirium, and related clinical outcomes in adult ICU patients. The group also used psychometric analyses to evaluate and compare pain, agitation/sedation, and delirium assessment tools. All task force members were allowed to review the literature supporting each statement and recommendation and provided feedback to the subcommittees. Group consensus was achieved for all statements and recommendations using the nominal group technique and the modified Delphi method, with anonymous voting by all task force members using E-Survey (http://www.esurvey.com). All voting was completed in December 2010. Relevant studies published after this date and prior to publication of these guidelines were referenced in the text. The quality of evidence for each statement and recommendation was ranked as high (A), moderate (B), or low/very low (C). The strength of recommendations was ranked as strong (1) or weak (2), and either in favor of (+) or against (-) an intervention. A strong recommendation (either for or against) indicated that the intervention's desirable effects either clearly outweighed its undesirable effects (risks, burdens, and costs) or it did not. For all strong recommendations, the phrase "We recommend …" is used throughout. A weak recommendation, either for or against an intervention, indicated that the trade-off between desirable and undesirable effects was less clear. For all weak recommendations, the phrase "We suggest …" is used throughout. In the absence of sufficient evidence, or when group consensus could not be achieved, no recommendation (0) was made. Consensus based on expert opinion was not used as a substitute for a lack of evidence. A consistent method for addressing potential conflict of interest was followed if task force members were coauthors of related research. The development of this guideline was independent of any industry funding. CONCLUSION These guidelines provide a roadmap for developing integrated, evidence-based, and patient-centered protocols for preventing and treating pain, agitation, and delirium in critically ill patients.

Abstract
OBJECTIVE To provide an update to the "Surviving Sepsis Campaign Guidelines for Management of Severe Sepsis and Septic Shock," last published in 2008. DESIGN A consensus committee of 68 international experts representing 30 international organizations was convened. Nominal groups were assembled at key international meetings (for those committee members attending the conference). A formal conflict of interest policy was developed at the onset of the process and enforced throughout. The entire guidelines process was conducted independent of any industry funding. A stand-alone meeting was held for all subgroup heads, co- and vice-chairs, and selected individuals. Teleconferences and electronic-based discussion among subgroups and among the entire committee served as an integral part of the development. METHODS The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system to guide assessment of quality of evidence from high (A) to very low (D) and to determine the strength of recommendations as strong (1) or weak (2). The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. Recommendations were classified into three groups: (1) those directly targeting severe sepsis; (2) those targeting general care of the critically ill patient and considered high priority in severe sepsis; and (3) pediatric considerations.

Abstract
As most critically ill or injured patients will require some degree of sedation, the goal of this paper was to comprehensively review the literature associated with use of sedative agents in the intensive care unit (ICU). The first and selected latter portions of this article present a narrative overview of the shifting paradigm in ICU sedation practices, indications for uninterrupted or prolonged ICU sedation, and the pharmacology of sedative agents. In the second portion, we conducted a structured, although not entirely systematic, review of the available evidence associated with use of alternative sedative agents in critically ill or injured adults. Data sources for this review were derived by searching OVID MEDLINE and PubMed from their first available date until May 2012 for relevant randomized controlled trials (RCTs), systematic reviews and/or meta-analyses and economic evaluations. Advances in the technology of mechanical ventilation have permitted clinicians to limit the use of sedation among the critically ill through daily sedative interruptions or other means. These practices have been reported to result in improved mortality, a decreased length of ICU and hospital stay and a lower risk of drug-associated delirium. However, in some cases, prolonged or uninterrupted sedation may still be indicated, such as when patients develop intracranial hypertension following traumatic brain injury. The pharmacokinetics of sedative agents have clinical importance and may be altered by critical illness or injury, co-morbid conditions and/or drug-drug interactions. Although use of validated sedation scales to monitor depth of sedation is likely to reduce adverse events, they have no utility for patients receiving neuromuscular receptor blocking agents. Depth of sedation monitoring devices such as the Bispectral Index (BIS©) also have limitations. Among existing RCTs, no sedative agent has been reported to improve the risk of mortality among the critically ill or injured. Moreover, although propofol may be associated with a shorter time to tracheal extubation and recovery from sedation than midazolam, the risk of hypertriglyceridaemia and hypotension is higher with propofol. Despite dexmedetomidine being linked with a lower risk of drug-associated delirium than alternative sedative agents, this drug increases risk of bradycardia and hypotension. Among adults with severe traumatic brain injury, there are insufficient data to suggest that any single sedative agent decreases the risk of subsequent poor neurological outcomes or mortality. The lack of examination of confounders, including the type of healthcare system in which the investigation was conducted, is a major limitation of existing pharmacoeconomic analyses, which likely limits generalizability of their results.

Abstract
BACKGROUND Adequate assessment and control of sedation play crucial roles in the proper performance of mechanical ventilation. METHODS A total of 30 patients with various pulmonary diseases were prospectively enrolled. The study population was randomized into two groups. The sedation assessment group (SAG) received active protocol-based control of sedation, and in the empiric control group (ECG), the sedation levels were empirically adjusted. Subsequently, daily interruption of sedation (DIS) was conducted in the SAG. RESULTS In the SAG, the dose of midazolam was significantly reduced by control of sedation (day 1, 1.3±0.5 µg/kg/min; day 2, 0.9±0.4 µg/kg/min; p<0.01), and was significantly lower than the ECG on day 2 (p<0.01). Likewise, on day 2, sedation levels were significantly lower in the SAG than in the ECG. Significant relationship was found between Ramsay sedation scale and Richmond agitation-sedation scale (RASS; r(s)=-0.57), Ramsay Sedation Scale and Bispectral Index (BIS; r(s)=0.77), and RASS and BIS (r(s)=-0.79). In 10 patients, who didn't require re-sedation after DIS, BIS showed the earliest and most significant changes among the sedation scales. Ventilatory parameters showed significant but less prominent changes, and hemodynamic parameters didn't show significant changes. No seriously adverse events ensued after the implementation of DIS. CONCLUSION Active assessment and control of sedation significantly reduced the dosage of sedatives in patients receiving mechanical ventilation. DIS, conducted in limited cases, suggested its potential efficacy and tolerability.

Abstract
Critically ill patients receiving extracorporeal membrane oxygenation (ECMO) are often noted to have increased sedation requirements. However, data related to sedation in this complex group of patients is limited. The aim of our study was to characterise the sedation requirements in adult patients receiving ECMO for cardiorespiratory failure. A retrospective chart review was performed to collect sedation data for 30 consecutive patients who received venovenous or venoarterial ECMO between April 2009 and March 2011. To test for a difference in doses over time we used a regression model. The dose of midazolam received on ECMO support increased by an average of 18 mg per day (95% confidence interval 8, 29 mg, P=0.001), while the dose of morphine increased by 29 mg per day (95% confidence interval 4, 53 mg, P=0.021) The venovenous group received a daily midazolam dose that was 157 mg higher than the venoarterial group (95% confidence interval 53, 261 mg, P=0.005). We did not observe any significant increase in fentanyl doses over time (95% confidence interval 1269, 4337 µg, P=0.94). There is a significant increase in dose requirement for morphine and midazolam during ECMO. Patients on venovenous ECMO received higher sedative doses as compared to patients on venoarterial ECMO. Future research should focus on mechanisms behind these changes and also identify drugs that are most suitable for sedation during ECMO.

Abstract
OBJECTIVES To determine the feasibility of conducting a sedation wake-up trial (SWT) plus a spontaneous breathing trial (SBT) in critically ill trauma patients based on the ability to implement the combined intervention; to measure and describe patients' physiological responses; and to maintain patient safety. METHODS A secondary analysis of the intervention group from a trial of 20 mechanically ventilated patients receiving SWT plus SBT in a trauma-intensive care unit. RESULTS Patients passed 67% of the 39 SWTs performed; those who failed presented RASS scores of +1 and +2 (70%), tachycardia (15%) or ventilator asynchrony (15%). Eighteen patients tolerated their first SBT, and after the second SBT, more than half of the patients were discontinued from the mechanical ventilator. A significant increase from the beginning to the end of the SWT was found in heart rate (p=.021), respiratory rate (p=.043) and systolic blood pressure (p=.04). Although these measures increased significantly, their overall mean did not increase by 20%. CONCLUSION SWT plus SBT was well tolerated and successfully implemented. Our data showed that it is not necessary to withhold continuous-infusion analgesia during the SWT.

Abstract
INTRODUCTION While one controlled trial found that a daily awakening and spontaneous breathing trial (DA-SBT) decreases time on mechanical ventilation (MV), there is a paucity of real-world data surrounding the development, implementation, and impact of DA-SBT protocols. We describe a multidisciplinary process improvement effort in 2, 10-bed medical intensive care units (MICUs) at a 330-bed academic medical center that focused on the development, implementation, and evaluation of a new DA-SBT protocol. METHODS A DA-SBT protocol, developed using results from a nursing survey literature and available institutional resources, was implemented after extensive clinician education and institution of quality reminders to boost use. Postprotocol compliance was evaluated. Use of sedation, DA and SBT practices, and clinical outcomes were retrospectively compared between the before and after DA-SBT protocol groups (ie, consecutive MICU patients requiring a continuously infused sedative [CIS] ≥24 hours). RESULTS In the after group (n = 32), the DA and SBT compliances were 44% and 84%, respectively. Compared with the before group (n = 33), after group patients received CIS on fewer days of MV (100% vs 67%, P = .003) and had their CIS down-titrated by ≥25% on more days of CIS (40% vs 71%, P = .006). Neither total CIS dose (P = .49), total MV days (P = .75), days of MV where a SBT occurred (P = .38), nor episodes of self-extubation (15% vs 6%, P = .43) differed between the 2 groups. CONCLUSION Despite the implementation of a DA-SBT protocol that was individualized to clinician preferences and institutional resources and accompanied by substantial education and reminders for use, compliance to the DA component of this protocol was low and duration of MV remained unchanged. Additional quality improvement strategies are needed to overcome barriers to DA-SBT protocol use that may not exist in controlled clinical trials.

Abstract
The continuous infusion of sedative agents is often necessary for critically ill patients. However, it has been associated with several disadvantages. Numerous interventions to reduce these risks have been evaluated, including the practice of interrupting sedative infusions on a daily basis. A literature search was conducted, and 7 studies were reviewed to evaluate the safety and effectiveness of daily interruption of sedative infusions and its outcomes. The implementation of daily sedation interruptions was suggested to minimize multiple complications associated with continuous sedative infusions and was not associated with intensive care-related complications or long-term psychological effects. Additional studies have revealed perceived barriers to the implementation of daily sedation interruptions. Further randomized controlled trials enrolling larger, more diverse samples are needed to provide more evidence regarding the safety and effectiveness of this intervention.

Abstract
Extracorporeal membrane oxygenation (ECMO) is a form of prolonged cardiopulmonary bypass used to temporarily sustain cardiac and/or respiratory function in critically ill patients. Extracorporeal membrane oxygenation further complicates the management of critically ill patients who already have profound physiologic derangements with consequent altered pharmacokinetics. The purpose of this study is to identify and critically review the published literature describing pharmacokinetics in the presence of ECMO. This review revealed a dearth of data describing pharmacokinetics during ECMO in critically ill adults, with most of the available data originating in neonates. Of concern, the present data indicate substantial variability and a lack of predictability in drug behavior in the presence of ECMO. The most common mechanisms by which ECMO affects pharmacokinetics are sequestration in the circuit, increased volume of distribution, and decreased drug elimination. While lipophilic drugs and highly protein-bound drugs (eg, voriconazole and fentanyl) are significantly sequestered in the circuit, hydrophilic drugs (eg, β-lactam antibiotics, glycopeptides) are significantly affected by hemodilution and other pathophysiologic changes that occur during ECMO. Although the published literature is insufficient to make any meaningful recommendations for adjusting therapy for drug dosing, this review systematically describes the available data enabling clinicians to make conclusions based on available data. Furthermore, this review serves to highlight the need for well-designed and conducted clinical and laboratory-based studies to provide the data from which robust dosing guidance can be developed to improve clinical outcomes in this most unwell cohort of patients.

Abstract
The Spanish Society of Critical Care Medicine (SEMICYUC) has recently published an updated version of Quality Indicators in Critical Care. Daily sedative interruption is included among them. As this practice is controversial, research studies are revised and guidelines for its implementation are proposed.

Abstract
Protocolized target-based sedation and analgesia is central to effective management of sedation. Important components include identifying goals and specific targets,using valid and reliable tools to measure pain, agitation, and sedation, and titrating a logically selected combination of sedatives and analgesics to defined end-points.A variety of approaches to structured management have been tested in controlled trials with major categories of (1) sedation algorithms and protocols and (2) daily interruption of sedation. Although not all studies that compare new interventions to “usual care” document dramatic improvements, many studies show that by reducing oversedation, using a structured approach, faster recovery from respiratory failure may ensue. The somewhat discrepant results illustrate, however, that various approaches,such as DIS, may not be optimal for all patients. Further research will be necessary to define these patients and examine alternative strategies. Finally, implementation of structured approaches to sedation management is a challenging, time-consuming process for clinicians that must be supported with sufficient resources to be successful.

Abstract
Limitations are inherent to surveys. Most surveys have low response rates, which raises the issue of responder bias. Another limitation of self-report surveys stems from the possible differences between stated and actual practice. That is, what physicians report that they do in surveys often contrasts significantly with what they do in observational studies, as highlighted by the Canadian surveys conducted in 2002 and 2008. Some surveys report estimates provided by ICU nurse managers or physician directors, potentially resulting in inaccurate estimates or data reflecting the individuals practice rather than the entire ICU. Surveys may not reflect how different specialists practice; for example, the German surveys collected data only in ICUs run by anesthesiologists.Notwithstanding these limitations, surveys provide a wealth of information on current practice and determinants of practice, and serve as a useful tool to guide future research and educational interventions. The authors identified substantial international variation in the use of sedative and analgesic drugs, and marked changes over the last 10 years. Overall, there is a trend toward lighter sedation, along with a shift from benzodiazepines toward propofol, and from morphine toward fentanyl and remifentanil. Despite the publication of numerous studies and guidelines for sedation and analgesia, actual practice differs from recommended practice, suggesting that the impact of clinical trials and guidelines on physician practice is quite low. It is clear that there remain substantial barriers to the incorporation of sedation scales, protocols,and daily interruption into routine ICU care.

Abstract
Little is known of nonpharmacologic and pharmacologic delirium prevention and treatment in the critical care setting. Trials emphasizing early mobilization suggest that this nonpharmacologic approach is associated with an improvement in delirium incidence. Titration and reduction of opiate analgesics and sedatives may improve subsyndromal delirium rates. All critical care caregivers should rigorously screen for alcohol abuse, apply alcohol withdrawal scales in alcoholic patients, and titrate sedative drugs accordingly. No nonpharmacologic approach or drug has been shown to be beneficial once delirium is established. Considering the importance and the consequences of delirium in the critical care setting, studies to further address prevention and rigorous trials addressing pharmacologic intervention are urgently needed.

Abstract
OBJECTIVE The reliability of electrocardiogram interpretation to diagnose myocardial ischemia in critically ill patients is unclear. In adults with septic shock, we assessed intra- and inter-rater agreement of electrocardiogram interpretation, and the effect of knowledge of troponin values on these interpretations. DESIGN Prospective substudy of a randomized trial of vasopressin vs. norepinephrine in septic shock. SETTING Nine Canadian intensive care units. PATIENTS Adults with septic shock requiring at least 5 μg/min of norepinephrine for 6 hrs. INTERVENTIONS Twelve-lead electrocardiograms were recorded before study drug, and 6 hrs, 2 days, and 4 days after study drug initiation. MEASUREMENTS Two physician readers, blinded to patient data and group, independently interpreted electrocardiograms on three occasions (first two readings were blinded to patient data; third reading was unblinded to troponin). To calibrate and refine definitions, both readers initially reviewed 25 trial electrocardiograms representing normal to abnormal. Cohen's Kappa and the φ statistic were used to analyze intra- and inter-rater agreement. RESULTS One hundred twenty-one patients (62.2 ± 16.5 yrs, Acute Physiology and Chronic Health Evaluation II 28.6 ± 7.7) had 373 electrocardiograms. Blinded to troponin, readers 1 and 2 interpreted 46.4% and 30.0% of electrocardiograms as normal, and 15.3% and 12.3% as ischemic, respectively. Intrarater agreement was moderate for overall ischemia (κ 0.54 and 0.58), moderate/good for "normal" (κ 0.69 and 0.55), fair to good for specific signs of ischemia (ST elevation, T inversion, and Q waves, reader 1 κ 0.40 to 0.69; reader 2 κ 0.56 to 0.70); and good/very good for atrial arrhythmias (κ 0.84 and 0.79) and bundle branch block (κ 0.88 and 0.79). Inter-rater agreement was fair for ischemia (κ 0.29), moderate for ST elevation (κ 0.48), T inversion (κ 0.52), and Q waves (κ 0.44), good for bundle branch block (κ 0.78), and very good for atrial arrhythmias (κ 0.83). Inter-rater agreement for ischemia improved from fair to moderate (κ 0.52, p = .028) when unblinded to troponin. CONCLUSIONS In patients with septic shock, inter-rater agreement of electrocardiogram interpretation for myocardial ischemia was fair, and improved with troponin knowledge.

Abstract
OBJECTIVE To establish whether continuous subglottic suctioning (CSS) could be cost-effective. DESIGN Cost-benefit analysis, based on a hypothetical replacement of conventional ventilation (CV) with CSS. SETTING A surgical intensive care unit (SICU) of a tertiary care university hospital in France. PATIENTS All consecutive patients receiving ventilation in the SICU in 2006. METHODS Efficacy data for CSS were obtained from the literature and applied to the SICU of our hospital. Costs for CV and CSS were provided by the hospital pharmacy; costs for ventilator-associated pneumonia (VAP) were obtained from the literature. The cost per averted VAP episode was calculated, and a sensitivity analysis was performed on VAP incidence and on the number of tubes required for each patient. RESULTS At our SICU in 2006, 416 patients received mechanical ventilation for 3,487 ventilation-days, and 32 VAP episodes were observed (7.9 episodes per 100 ventilated patients; incidence density, 9.2 episodes per 10,000 ventilation-days). Based on the hypothesis of a 29% reduction in the risk of VAP with CSS than CV, 9 VAP episodes could have been averted. The additional cost of CSS for 2006 was estimated to be €10,585.34. The cost per averted VAP episode was €1,176.15. Assuming a VAP cost of €4,387, a total of 3 averted VAP episodes would neutralize the additional cost. For a low VAP incidence of 6.6%, the cost per averted VAP would be €1,323. If each patient required 2 tubes during ventilation, the cost would be €1,383.69 per averted VAP episode. CONCLUSION Replacement of CV with CSS was cost-effective even when assuming the most pessimistic scenario of VAP incidence and costs.

Abstract
Sedation is often used to improve comfort, reduce anxiety and stress and to facilitate nursing care of critically ill patients in the intensive care unit. This meta-analysis examined the benefits and risks of daily sedation interruption in critically ill adult patients. A total of five randomised controlled trials, comparing daily sedation interruption with no interruption in 699 critically ill patients, from the Cochrane controlled trials register, Embase and MEDLINE databases (1966 to April 2010) were identified and subject to meta-analysis. With the limited data available, daily sedation interruption was not associated with a significant reduction in duration of mechanical ventilation, length of intensive care unit and hospital stay, or mortality. Daily sedation interruption was associated with a reduced risk of requiring tracheostomy (odds ratio 0.57, 95% confidence interval 0.35 to 0.92, P = 0.02; F = 3%) but not an increased risk of removal of the endotracheal tube by the patients (odds ratio 1.3, 95% confidence interval 0.41 to 4.10, P = 0.65; F = 49%). The current evidence suggests that daily sedation interruption appears to be safe, but the significant heterogeneity and small sample sizes of the existing studies suggest that large randomised controlled studies with long-term survival follow-up are needed before daily sedation interruption can be recommended as a standard sedation practice for critically ill adult patients.

Abstract
PURPOSE To evaluate efficacy and adverse events related to inhaled sevoflurane for long-term sedation compared with standard intravenous (i.v.) sedation with propofol or midazolam. METHODS Randomized controlled trial. Sixty intensive care unit (ICU) patients expected to require more than 24 h sedation were randomly assigned to one of three groups: group S, inhaled sevoflurane; group P, i.v. propofol; group M, i.v. midazolam. All patients also received i.v. remifentanil for goal-directed sedation (Ramsay scale and pain score) until extubation or for a maximum of 96 h. Primary end points were wake-up times and extubation delay from termination of sedative administration. Proportion of time within Ramsay score 3-4, i.v. morphine consumption at 24 h post extubation, hallucination episodes after end of sedation, adverse events, inorganic fluoride plasma levels, and ambient sevoflurane concentrations were recorded. RESULTS Forty-seven patients were analyzed. Wake-up time and extubation delay were significantly (P<0.01) shorter in group S (18.6 ± 11.8 and 33.6 ± 13.1 min) than in group P (91.3 ± 35.2 and 326.11 ± 360.2 min) or M (260.2 ± 150.2 and 599.6 ± 586.6 min). Proportion of time within desired interval of sedation score was comparable between groups. Morphine consumption during the 24 h following extubation was lower in group S than in groups P and M. Four hallucination episodes were reported in group P, five in group M, and none in group S (P=0.04). No hepatic or renal adverse events were reported. Mean plasma fluoride value was 82 μmol l(-1) (range 12-220 μmol l(-1)), and mean ambient sevoflurane concentration was 0.3 ± 0.1 ppm. CONCLUSIONS Long-term inhaled sevoflurane sedation seems to be a safe and effective alternative to i.v. propofol or midazolam. It decreases wake-up and extubation times, and post extubation morphine consumption, and increases awakening quality.
