ath. The more frequent the double-triggering occurred, the more serious the pendelluft phenomenon was. A higher pendelluft volume of normal breath and a higher respiratory rate were related to severity of double-triggering.
During PSV, the abnormal movement of air in the lungs (pendelluft phenomenon) was more likely to occur in double-triggering especially in double-triggered breath. The more frequent the double-triggering occurred, the more serious the pendelluft phenomenon was. A higher pendelluft volume of normal breath and a higher respiratory rate were related to severity of double-triggering.
To investigate the diagnostic value of neutrophil CD64 index in sepsis patients in intensive care unit (ICU).

A prospective case-control study was conducted, the patients admitted to ICU of Jiangbei People's Hospital Affiliated to Nantong University from December 2016 to June 2020 were enrolled. According to the criteria of Sepsis 3, 107 patients diagnosed with sepsis were classified as the sepsis group, 112 patients without infection were classified as control group. Peripheral venous blood samples were collected within 24 hours after ICU admission, neutrophil CD64 index, C-reactive protein (CRP), procalcitonin (PCT), white blood cell count (WBC) were detected. Receiver operating characteristic curve (ROC curve) was used to evaluate the diagnostic value of neutrophil CD64 index, CRP, PCT and WBC for sepsis.

The neutrophil CD64 index, CRP and PCT in sepsis group were significantly higher than those in control group [neutrophil CD64 index 9.03±5.59 vs. 3.18±1.50, CRP (mg/L) 146.9±68.3 vs. 46.5±35.8, PCT (ng/L) 31.82±14.71 vs. 1.87±1.42, all P < 0.05]. selleck products ROC curve analysis showed that neutrophil CD64 index, CRP and PCT had certain diagnostic value for sepsis, the area under ROC curve (AUC) were 0.924, 0.915 and 0.879, respectively, the 95% confidence intervals (95%CI) were 0.871-0.978, 0.855-0.975, 0.807-0.951, respectively, P values were 0.016, 0.017 and 0.026, respectively. Among the three indicators, the diagnostic value of neutrophil CD64 index was much higher. When the optimal cut-off value was 4.32, the sensitivity and specificity were 83.6% and 88.7%, respectively, which were higher than the sensitivity (75.1%, 76.3%) and specificity (87.2%, 82.5%) of CRP and PCT.

Neutrophil CD64 index is a valuable biomarker for the diagnosis of sepsis in ICU.

To investigate clinicians' compliance with the 2018 Surviving Sepsis Campaign (SSC) update "1-hour sepsis Bundle therapy" (1-hour Bundle) when treating patients with Sepsis 3 in the intensive care unit (ICU), and to analyze its impact on patient outcomes.

A multicenter, prospective observational cohort study was conducted. A total of 153 ICU patients in Ziyang First People's Hospital, Ziyang People's Hospital and Yanjiang District People's Hospital who were diagnosed of sepsis by the definition and diagnostic criteria of Sepsis 3 from January 2019 to December 2020 were selected. Among them, 95 patients who had completed 1-hour Bundle were divided into the Bundle compliance group. 58 patients who did not complete the Bundle within 1 hours were classified as the Bundle non-compliance group. The distribution of pathogenic bacteria and infected sites, 1-hour Bundle compliance and 28-day survival in the 3 hospitals were analyzed. Univariate analysis was used to analyze the risk factors affecting the prognostictimicrobial use and microbial culture retention before antimicrobial use. The 28-day survival rate in the Bundle compliance group was significantly higher than that in the Bundle non-compliance group, suggesting that the 1-hour Bundle regimen can improve the prognosis of patients with sepsis.
The 1-hour Bundle compliance rate of ICU patients with sepsis in 3 hospitals of Ziyang City was 62.09%, and the compliance is still to be improved, especially for the 2 aspects of empirical antimicrobial use and microbial culture retention before antimicrobial use. The 28-day survival rate in the Bundle compliance group was significantly higher than that in the Bundle non-compliance group, suggesting that the 1-hour Bundle regimen can improve the prognosis of patients with sepsis.
To evaluate the clinical value of neutrophil/lymphocyte ratio (NLR) in early prediction of the incidence of sepsis-induced organ dysfunction and 28-day mortality.

A retrospective study was conducted in 815 adult patients with sepsis admitted to the department of critical care medicine of the First Affiliated Hospital of China Medical University from January 2017 to December 2019. The clinical data including age, gender and complication were collected, and the peripheral blood routine indexes at 24, 48 and 72 hours after the diagnosis of sepsis were collected, and the NLR was calculated. The primary endpoint of the study was the incidences of sepsis related acute kidney injury (AKI), acute respiratory distress syndrome (ARDS), disseminated intravascular coagulation (DIC) and acute liver failure (ALF); the secondary endpoint was the 28-day in-hospital mortality in septic patients with organ dysfunction. Univariate and multivariate Logistic regression were used to analyze the risk factors of organ dysfunctio28-day mortality in patients with sepsis. ROC curve showed that the AUC of NLR at 48 hours was 0.598, 95%CI was 0.540-0.658, P = 0.02; when the cut-off value was 10.1, the sensitivity and specificity for predicting 28-day mortality was 75.2% and 58.0%, respectively; the AUC of NLR at 72 hours was 0.595, 95%CI was 0.536-0.655, P = 0.03; when the cut-off value was 9.24, the sensitivity and specificity for predicting 28-day mortality was 75.3% and 59.9%, respectively.

NLR cannot predict the occurrence of AKI, ARDS, DIC and ALF in sepsis in early stage. NLR has a certain clinical value in predicting 28-day mortality in patients with sepsis, but its predictive efficiency is low.
