Gender differences in mortality and quality of life after septic shock: A post-hoc analysis of the ARISE study

期刊: JOURNAL OF CRITICAL CARE, 2020; 55 ()

Purpose: To assess the impact of gender and pre-menopausal state on short- and long-term outcomes in patients with septic shock. Material and methods: Cohort study of the Australasian Resuscitation in Sepsis Evaluation (ARISE) trial, an international randomized controlled trial comparing early goal-directed therapy (EGDT) to usual care in patients with early septic shock, conducted between October 2008 and April 2014. The primary exposure in this analysis was legal gender and the secondary exposure was pre-menopausal state defined by chronological age (<= 50 years). Results: 641 (40.3%) of all 1591 ARISE trial participants in the intention-to-treat population were females and overall, 337 (21.2%) (146 females) patients were 50 years of age or younger. After risk-adjustment, we could not identify any survival benefit for female patients at day 90 in the younger (<= 50 years) (adjusted Odds Ratio (aOR): 0.91 (0.46-1.89), p = .85) nor in the older (>50 years) age-group (aOR: 1.10 (0.81-1.49), p = .56). Similarly, there was no gender-difference in ICU, hospital, 1-year mortality nor quality of life measures. Conclusions: This post-hoc analysis of a large multi-center trial in early septic shock has shown no short- or long-term survival effect for women overall as well as in the pre-menopausal age-group.

The effects of an enteral nutrition feeding protocol on critically ill patients: A prospective multi-center, before-after study

期刊: JOURNAL OF CRITICAL CARE, 2020; 56 ()

Purpose: The aim of this study was to explore the effects of an enteral nutrition (EN) feeding protocol in critically ill patients. Methods: This was a prospective multi-center before-after study. We compared energy related and prognostic indicators between the control group (pre-implementation stage) and intervention group (post-implementation stage). The primary endpoint was the percentage of patients receiving EN within 7 days after ICU admission. Results: 209 patients in the control group and 230 patients in the intervention group were enrolled. The implementation of the EN protocol increased the percentage of target energy reached from day 3 to day 7, and the difference between two groups reached statistical significance in day 6 (P = .01) and day 7 (P = .002). But it had no effects on proportion of patient receiving EN (P = .65) and start time of EN (P = .90). The protocol application might be associated with better hospital survival (89.1% vs 82.8%, P = .055) and reduce the incidence of EN related adverse (P = .004). There was no difference in ICU length of stay, duration of mechanical ventilation and ICU cost. Conclusion: The implementation of the enteral feeding protocol is associated with improved energy intake and a decreased incidence of enteral nutrition related adverse events for critically ill patients, but it had no statistically beneficial effects on reducing the hospital mortality rate.

Noninvasive ventilation support during fiberoptic bronchoscopy-guided nasotracheal intubation effectively prevents severe hypoxemia

期刊: JOURNAL OF CRITICAL CARE, 2020; 56 ()

Purpose: This study investigated the feasibility and efficacy of continuous noninvasive ventilation (NIV) support with 100% oxygen using a specially designed face mask, for reducing desaturation during fiberoptic bronchoscopy (FOB)-guided intubation in critically ill patients with respiratory failure. Materials and methods: This was a single-center prospective randomized study. All patients undergoing FOB-guided nasal tracheal intubation were randomized to bag-valve-mask ventilation or NIV for preoxygenation followed by intubation. The NIV group were intubated through a sealed hole in a specially designed face mask during continuous NIV support with 100% oxygen. Control patients were intubated with removal of the mask and no ventilatory support. Results: We enrolled 106 patients, including 53 in each group. Pulse oxygen saturation (SpO(2)) after preoxygenation (99% (96%-100%) vs. 96% (90%-99%), p = .001) and minimum SpO(2) during intubation (95% (87%-100%) vs. 83% (74%-91%), p < .01) were both significantly higher in the NIV compared with the control group. Severe hypoxemic events (SpO(2) < 80%) occurred less frequently in the NIV group than in controls (7.4% vs. 37.7%, respectively; p < .01). Conclusions: Continuous NIV support during FOB-guided nasal intubation can prevent severe desaturation during intubation in critically ill patients with respiratory failure. (C) 2019 Elsevier Inc.

Non-pharmacological interventions to reduce the incidence and duration of delirium in critically ill patients: A systematic review and network meta-analysis

期刊: JOURNAL OF CRITICAL CARE, 2020; 60 ()

Objective: To compare non-pharmacological interventions in their ability to prevent delirium in critically ill patients, and find the optimal regimen for treatment. Methods: Literature searches were conducted using PubMed, Embase, CINAHL, and Cochrane Library databases until the end of June 2019. We estimated the risk ratios (RRs) for the incidence of delirium and in-hospital mortality and found the mean difference (MD) for delirium duration and the length of ICU stay. The probabilities of interventions were ranked based on clinical outcomes. The study was registered on PROSPERO (CRD42020160757). Results: Twenty-six eligible studies were included in the network meta-analysis. Studies were grouped into seven intervention types: physical environment intervention (PEI), sedation reducing (SR), family participation (FP), exercise program (EP), cerebral hemodynamics improving (CHI), multi-component studies (MLT) and usual care (UC). In term of reducing the incidence of delirium, the two most effective interventions were FP (risk ratio (RR) 0.19, 95% confidence interval (CI) 0.08 to 0.44; surface under the cumulative ranking curve (SUCRA) = 94%) and MLT (RR 0.43, 95% CI 0.30 to 0.57; SUCRA = 68%) compared with observation. Although all interventions demonstrated nonsignificant efficacy in regards to delirium duration and the length of the patient's stay in the ICU, MLT (SUCRA = 78.6% and 71.2%, respectively) was found to be the most effective intervention strategy. In addition, EP (SUCRA = 97.2%) facilitated a significant reduction in hospital mortality, followed in efficacy by MLT (SUCRA = 73.2%), CHI (SUCRA = 35.8%), PEI (SUCRA = 34.8%), and SR (SUCRA = 31.8%). Conclusions: Multi-component strategies are overall the optimal intervention techniques for preventing delirium and reducing ICU length of stay in critically ill patients byway of utilizing several interventions simultaneously. Additionally, family participation as a method of patient-centered care resulted in better outcomes for reducing the incidence of delirium. (C) 2020 Elsevier Inc. All rights reserved.

Association between plasma adiponectin levels and left ventricular systolic dysfunction in sepsis patients

期刊: JOURNAL OF CRITICAL CARE, 2020; 60 ()

Purpose: As a well-known cardioprotective factor, the relevance of adiponectin (APN) to heart function following sepsis remains largely unknown. The present study evaluated the effects of plasma APN levels on heart function and 28-day mortality in sepsis patients. Materials and methods: This was a prospective study that was performed with 98 patients with sepsis and 32 controls. Left ventricular systolic dysfunction (LVSD) was defined as a left ventricular ejection fraction (LVEF) <= 45% based on echocardiography. The effects of APN on the development of sepsis-related LVSD and prediction of 28day mortality were evaluated. Results: Plasma APN levels significantly decreased in sepsis patients compared with controls, with rising severity of illness, and positively correlated with the LVEF and stroke volume index. Sepsis patients with LVSD had lower APN levels than patients without LVSD. According to the receiver operating characteristic curve, plasma APN levels had the comparable value in prediction of LVSD incidence than those conditional factors, including brain natriuretic peptide (BNP) and highly sensitive cardiac troponin T (hsTnT). Twenty-three of the 98 sepsis patients (23.47%) died at 28 days. Adiponectin levels were an independent predictive factor for 28-day mortality. Conclusions: Low APN levels were associated with the incidence of LVSD and 28-day mortality in sepsis patients. Adiponectin may be a novel factor that may be useful for the diagnosis of LVSD.

The role of ultrasound in front-of-neck access for cricothyroid membrane identification: A systematic review

期刊: JOURNAL OF CRITICAL CARE, 2020; 60 ()

Purpose: Conventional palpation techniques for cricothyroid membrane (CTM) identification are inaccurate and unreliable. Ultrasound plays a multi-faceted role in airway management, however there is limited literature around its use for CTM identification prior to cricothyrotomies. This review sought to compare ultrasound to palpation in the general population, identify its indications in subjects with ill-defined neck anatomy, and determine its role in defining neck anatomy. Methods: Two reviewers independently assessed titles, abstracts and full-text English articles through the Ovid Medline and EMBASE databases. Studies related to ultrasound for CTM assessment and/or cricothyrotomy in subjects older than 12 years were included. Results: Fourteen studies were selected. Compared to palpation, ultrasound has greater accuracy, but longer CTM identification times in those with normal airway anatomy. Interestingly, ultrasound offers comparable times to palpation in patients with difficult airways. Ultrasound also helps define anatomical parameters in the neutral and extended neck positions thereby underscoring the importance of neck positioning during cricothyrotomies and confirming consensus-based incision recommendations set by the Difficult Airway Society. Conclusion: Ultrasound appears to be superior to palpation for CTM localization especially in those with difficult airway anatomy and objectively defines neck anatomy. Its pre-emptive use should be incorporated during difficult airway management. (C) 2020 Elsevier Inc. All rights reserved.

The characteristics and outcomes of 681 severe cases with COVID-19 in China

期刊: JOURNAL OF CRITICAL CARE, 2020; 60 ()

Purpose: To clarify the epidemiological, clinical, and therapeutic features of patients with severe COVID-19. Methods: In this study, we enrolled 681 patients with confirmed cases of severe COVID-19. The epidemiological, demographic, clinical, laboratory, treatment, and outcome data were collected. Results: The median age of the study participants was 65 years, 53.2% were male, and 104 (15.3%) died. Age, Neutrophil-To-Lymphocyte Ratio (NLR), acute myocardial injury, and levels of C-reactive protein (CRP), lactate dehydrogenase (LDH), and CD3 T cells counts were independently associated with death, while arbidol and ribavirin were protective from death. The combination of NLR and acute myocardial injury on admission (AUC = 0.914) predicted mortality better than NLR, CRP, LDH, and acute myocardial injury. There were 312 (45.8%) patients with cardiovascular disease, of whom 23.4% died. beta-blockers, ACEI/ARB, arbidol, and ribavirin might have a beneficial effect for severe COVID-19 patients with cardiovascular disease. Conclusion: The combination of NLR and acute myocardial injury on admission was highly predictive of mortality and survival. Clinicians should adopt more aggressive strategies for patients with a high NLR (>6.66) combined with myocardial injury. beta-blockers and ACEI/ARB, as well as arbidol and ribavirin, were effective in COVID-19 patients with cardiovascular disease.

Timeline of sepsis bundle component completion and its association with septic shock outcomes

期刊: JOURNAL OF CRITICAL CARE, 2020; 60 ()

Purpose: To assess the impact of the timeline of sepsis bundle completion with clinical outcomes in septic shock. Materials and methods: We retrospectively studied adult (>= 18 years) patients with septic shock from January 1, 2006, through May 31, 2018, who were admitted to the intensive care unit in Mayo Clinic, Rochester. We divided patients into three groups based on the SSC compliant 1) <1h, 2) 1.1 to 3 h, 3) >3 h after the time of septic shock diagnosis. Results: We enrolled 1052 septic shock patients, among 8% were in group 1, 26% in group 2, and the remaining in group 3. Those who completed all bundle components within 3 h had the lowest 28-day mortality (17.5% vs. 31.4%, p<.001) and higher survival at 90 days (HR = 0.67; 95% CI 0.55-0.80; p<.001). Sepsis bundle completion in <1 h had no significant advantage in 28-day mortality (21.5% vs.15.9%, p = .4) or 90-day survival compared with group 2 (HR = 1.08; 95% CI 0.77-1.53; p = .6). Conclusions: We showed an association between the completion of SSC bundle components within three hours with lower mortality or earlier shock reversal. This relationship was not evident when compared to bundle completion in 1 h vs. within 3 h. (C) 2020 Elsevier Inc. All rights reserved.

Informed consent procedures in patients with an acute inability to provide informed consent: Policy and practice in the CENTER-TBI study

期刊: JOURNAL OF CRITICAL CARE, 2020; 59 ()

Purpose: Enrolling traumatic brain injury (731) patients with an inability to provide informed consent in research is challenging. Alternatives to patient consent are not sufficiently embedded in European and national legislation, which allows procedural variation and bias. We aimed to quantify variations in informed consent policy and practice. Methods: Variation was explored in the CENTER-TBI study. Policies were reported by using a questionnaire and national legislation. Data on used informed consent procedures were available for 4498 patients from 57 centres across 17 European countries. Results: Variation in the use of informed consent procedures was found between and within EU member states. Proxy informed consent (N = 1377;64%) was the most frequently used type of consent in the ICU, followed by patient informed consent (N 426;20%) and deferred consent (N 334;16%). Deferred consent was only actively used in 15 centres (26%), although it was considered valid in 47 centres (82%). Conclusions: Alternatives to patient consent are essential for TBI research. While there seems to be concordance amongst national legislations, there is regional variability in institutional practices with respect to the use of different informed consent procedures. Variation could be caused by several reasons, including inconsistencies in clear legislation or knowledge of such legislation amongst researchers. (C) 2020 Published by Elsevier Inc.
