AbstractPatient–ventilator asynchrony (PVA) is commonly encountered during mechanical ventilation of critically ill patients. Estimates of PVA incidence vary widely. Type, risk factors, and consequences of PVA remain unclear. We aimed to measure the incidence and identify types of PVA, characterize risk factors for development, and explore the relationship between PVA and outcome among critically ill, mechanically ventilated adult patients admitted to medical, surgical, and medical-surgical intensive care units in a large academic institution staffed with varying provider training background. A single center, retrospective cohort study of all adult critically ill patients undergoing invasive mechanical ventilation for ≥ 12 h. A total of 676 patients who underwent 696 episodes of mechanical ventilation were included. Overall PVA occurred in 170 (24%) episodes. Double triggering 92(13%) was most common, followed by flow starvation 73(10%). A history of smoking, and pneumonia, sepsis, or ARDS were risk factors for overall PVA and double triggering (all P < 0.05). Compared with volume targeted ventilation, pressure targeted ventilation decreased the occurrence of events (all P < 0.01). During volume controlled synchronized intermittent mandatory ventilation and pressure targeted ventilation, ventilator settings were associated with the incidence of overall PVA. The number of overall PVA, as well as double triggering and flow starvation specifically, were associated with worse outcomes and fewer hospital-free days (all P < 0.01). Double triggering and flow starvation are the most common PVA among critically ill, mechanically ventilated patients. Overall incidence as well as double triggering and flow starvation PVA specifically, portend worse outcome.

Abstract:Background:In the management of subarachnoid hemorrhage (SAH), the potential for early complications and the centralization of limited resources often challenge the delivery of timely neurosurgical care. We sought to determine the impact of proximity to the accepting neurosurgical centre on outcomes following aneurysmal SAH.Methods:Using administrative data, we analyzed patients undergoing treatment for aneurysmal subarachnoid hemorrhage at neurosurgical centres in Ontario between 1995 and 2004. We compared mortality for patients receiving treatment at a centre in their county (in-county) versus those treated from outside counties (out-of-county). We also examined the impact of distance from the patient's residence to the treating centre.Results:The mortality rates were significantly lower for in-county versus out-of-county patients (23.5% vs. 27.6%, p=0.009). This advantage remained significant after adjusting for potential confounders (HR=0.84, p=0.01). The relationship between distance from the treating centre and mortality was biphasic. Under 300km, mortality increased with increasing distance. Over 300km, a survival benefit was observed.Conclusions:Proximity to the treating neurosurgical centre impacts survival after aneurysmal SAH. These results have significant implications for the triage of these critically ill patients.

Persistent Thrombocytopenia

Thrombocytopenia is common among surgical critically ill patients. The relationship between the duration of thrombocytopenia and mortality is not well studied. This retrospective 12-month cohort study was designed to evaluate the association between persistent thrombocytopenia and mortality among surgical critically ill patients to determine the risk factors for persistent thrombocytopenia. The study included adult patients consecutively admitted to the surgical intensive care unit (SICU) at our institution. Patients with a diagnosis of thrombocytopenia were identified from a prospective critical care database. We defined patients with persistent thrombocytopenia as those with thrombocytopenia lasting more than 7 consecutive days. The primary outcome of this study was 28-day mortality and the secondary outcomes were lengths of SICU stay and hospital stay. Fifty-one patients experienced persistent thrombocytopenia and 71 experienced nonpersistent thrombocytopenia. Among patients with persistent thrombocytopenia, mortality was significantly higher, and SICU and hospital stays were longer than those with nonpersistent thrombocytopenia. Risk factor analysis failed to predict which patients with thrombocytopenia would develop into persistent thrombocytopenia. Persistent thrombocytopenia is a clinically significant disorder and is associated with poorer outcomes. Future studies are needed to further define this process.

Abstract Background The relationship between fibrosis-4 (FIB-4) index and clinical outcomes in patients with acute kidney injury (AKI) is unclear. We aimed to investigate the association between FIB-4 index and all-cause mortality in critically ill patients with AKI. Methods We used data from the Multiparameter Intelligent Monitoring in Intensive Care III (MIMIC-III) database (v1.4). The FIB-4 score was calculated using the existing formulas. logistic regression model, and Cox proportional hazards model were used to assessed the relationship between the FIB-4 index and in-hospital,28-day and 90-day mortality, respectively. Results A total of 3592 patients with AKI included in the data analysis. 395 (10.99%) patients died during hospitalization and 458 (12.74%) patients died in 28-day. During the 90-day follow-up, 893 (22.54%) patients were dead. An elevated FIB-4 value was significantly associated with increased in-hospital mortality when used as a continuous variable (odds ratio [OR] 1.183, 95% confidence interval [CI] 1.072–1.305, P = 0.002) and as a quartile variable (OR of Q2 to Q4 1.216–1.744, with Q1 as reference). FIB-4 was positively associated with 28-day mortality of AKI patients with hazard ratio (HR) of 1.097 (95% CI 1.008, 1.194) and 1.098 (95% 1.032, 1.167) for 90-day mortality, respectively. Conclusion This study demonstrated the FIB-4 index is associated with clinical outcomes in critically ill patients with acute kidney injury.

Background Patients with SARS-CoV-2 infection could develop severe disease requiring critical care admission. Case reports indicated high incidence of hypertriglyceridemia (HTG) in critically ill patients infected with SARS-CoV-2, which might be related to the drugs. Objective We sought to determine the risk factors associated with HTG in this population and to investigate the relationship between HTG and lipase. Methods A retrospective observational study was conducted at our hospital between March 1 and June 30, 2020. Patients were included if they were ≥18 years old, admitted to the intensive care unit (ICU), tested positive for SARS-CoV-2, and had triglycerides (TG) checked during their hospital stay. Results Of the 111 critically ill patients, 103 patients were included. Males comprised 88.3% of the sample. The median TG at baseline was 197.4 (IQR: 139.8-283) mg/dL. The lipase median level at baseline was 23.00 (IQR: 0.00-69.50) IU/L. The results of the mixed-effects logistic regression analysis indicated that patient-level variables, favipiravir use, blood glucose level, and propofol use were significantly associated with HTG. There was no relationship between lipase and TG levels over time. Furthermore, TG concentrations over time showed a similar trend to inflammatory markers. Conclusion and Relevance The incidence of clinically significant HTG was high and was associated with propofol and favipiravir use. HTG might reflect the high inflammatory state in these patients. Clinicians should look at the full picture before changing therapies based only on HTG. Our findings need to be replicated in a larger prospective study.

Background: APACHE Score is an important criterion for determining the patient prognosis, especially in critically ill patients. According to significantly changes in the serum levels of thyroidal hormones in patients, especially in critically ill patients, the aim of the present study was to evaluate the relationship between thyroid function and APACHE 4 score in the prognosis of the traumatic patients admitted in surgery ICU. Method & Material: In a descriptive-analytical study, 90 patients with multiple trauma were studied. Thyroid hormones and APACHE 4 Score were evaluated on 1st, 5th and10th days of admission for each patient. Their clinical features and duration of hospitalization, either in trauma unit or ICU, elation between thyroidal hormones and APACHE 4 Score, duration of hospitalization, and survival of patients were evaluated. Results: This study included 90 patients. A statistically significant relation was detected between thyroid hormones (TT3) and APACHE 4 Score and duration of hospitalization. Conclusion: TT3 might be utilized as a prognostic factor in the traumatic patients admitted to ICU.

Abstract The standard for monitoring sedation levels in critically ill patients is intermittent bedside evaluation, and is prone to anchoring bias. Quantitative electroencephalography (qEEG) allows automated processing of recorded brain electrical activity and could be used to continuously monitor level of consciousness in critically ill patients. The majority of qEEG studies have included persons 80 years of age or less, and the qEEG profiles of nonagenarians have been incompletely characterized. Knowledge of the qEEG patterns of patients 90 years and older is essential for appropriate interpretation of such metrics in this population. This retrospective cohort study characterized qEEG profiles of acutely ill nonagenarians. We investigated whether the relationship between qEEG and level of consciousness differed between patients with and without a history of dementia. We included patients 90-100 years old admitted to Vanderbilt University Medical Center who underwent EEG and as part of their clinical care. We compared qEEG features to nursing-defined level of arousal as measured by the Richmond Agitation-Sedation Scale (RASS) in patients with and without history of dementia. Between January and December 2019, 26 nonagenarians underwent EEG for clinical purposes. One study was excluded due to excessive artifact. Of the remaining, 6 (24%) were male and 18 (72%) were Caucasian. Among all patients, RASS decreased with increases in EEG theta variability (coefficient -7.7, 95%CI -10.6 to -4.8). This relationship was not significantly modified by history of dementia (coefficient of interaction term -0.36, 95%CI -3.7 to 2.9). Dementia does not impact qEEG features of level of consciousness in nonagenarians.
