Objective:To investigate the association between early central venous pressure (CVP) measurement and mortality in patients with sepsis.Methods:The adult patients with sepsis were identified from the health data of Medical Information Mart for Intensive Care-Ⅲ v1.4 (MIMIC-Ⅲ v1.4). Data of all adult patients with sepsis were collected, including gender, age, comorbidities, length of survival, total length of hospital stay and intensive care unit (ICU) stay, sequential organ failure assessment (SOFA) score, vital signs, laboratory test results on the first day, vasoactive agents usage, fluid input, urine output and fluid balance on the first day, need for renal replacement therapy and mechanical ventilation, diagnosis of sepsis, and the time and value of the first CVP measurement in the ICU. Patients were divided into early measurement and control groups based on whether or not they had a CVP measurement within the first 6 hours of ICU stay. According to the time of the first CVP measurement, the patients were subdivided into four subgroups: ≤ 3 hours, 4-6 hours, 7-12 hours and no measurement within 12 hours. The primary endpoint was 28-day mortality. The relationship between initial CVP and mortality was analyzed by Lowess smoothing method. Kaplan-Meier survival analysis and Log-Rank test were performed for univariate analysis. Cox regression analysis was performed for multivariate analysis to estimate the relationship between timeliness of CVP measurement and mortality.Results:A total of 4 733 sepsis patients were enrolled, 1 673 of whom had CVP measured within 6 hours of admission to the ICU, and the other 3 060 patients served as the control group. There were no differences in demographic characteristics and underlying diseases between the two groups, except that the early CVP measurement group had less underlying renal failure compared with control group. The early CVP measurement group had higher lactic acid (Lac) levels and SOFA scores, indicating worse severity of disease as compared with control group. The 28-day mortality in the early CVP measurement group was significantly lower than that in the control group (34.2% vs. 40.7%, P < 0.01). The early CVP measurement group had shorter length of total hospitalization and longer length of ICU stay, higher rate of mechanical ventilation and vasoactive agents dependent, and more fluid input and fluid balanced in the first day of ICU stay compared with control group. Lowess smoothing analysis showed that a "U"-shaped relationship between initial CVP and mortality was identified, suggesting that too high or too low initial CVP was associated with worse survival. Kaplan-Meier survival analysis showed that compared with the patients without early CVP measurement within 12 hours, the cumulative survival rate of patients with CVP measured within 3 hours was significantly higher (66.7% vs. 59.1%; Log-Rank test: χ2 = 15.810, adjusted P < 0.001); while no significant difference was found in patients with CVP measured between 4 hours and 6 hours and between 7 hours and 12 hours compared with the patients without early CVP measurement within 12 hours (64.4%, 60.3% vs. 59.1%; Log-Rank test: χ2 values were 5.630 and 0.100, and adjusted P values were 0.053 and > 0.999, respectively). Cox multivariate analysis showed that the Cox proportional risk model was established by taking patients without CVP measurement within 12 hours as reference, timely CVP measurement after ICU admission was associated with reduced 28-day mortality of patients with sepsis [≤3 hours: hazard ratio ( HR) = 0.65, 95% confidence interval (95% CI) was 0.55-0.77, P < 0.001; 4-6 hours: HR = 0.72, 95% CI was 0.60-0.87, P = 0.001; 7-12 hours: HR = 0.80, 95% CI was 0.66-0.98, P = 0.032] after the confounding variables (gender, age, SOFA score, initial Lac, renal failure, maximal blood glucose and white blood cell count, and minimal platelet count within 24 hours) were adjusted. Conclusions:Early CVP measurement is associated with decreased 28-day mortality in patients with sepsis. CVP should be considered as a valuable and easily accessible safety parameter during early fluid resuscitation.

Objective To evaluate the prognostic value of arterial blood lactate clearance based on central venous oxygen saturation and perfusion index in patients with septic shock related myocardial injury after early goal-directed therapy.Methods One hundred and fifty-seven patients with septic shock after early resuscitation were enrolled from August 2013 to July 2016 in ICU at Peking Union Medical College Hospital.Parameters indicating early resuscitation included central venous pressure (CVP) 8-12 mmHg (1 mmHg=0.133 kPa),mean arterial pressure (MAP)＞65 mmHg,central venous oxygen saturation(ScvO2)＞70％ and urine volume (UO) ＞0.Sml · kg-1 · h-1 and arterial blood lactatc (Lac) ＞2 mmoL/L.Patients were divided into group A [ScvO2＞80％ and perfusion index (PI)＞1.4],group B(ScvO2＞80％ and PI＜1.4),group C (ScvO2＜80％ and PI＞1.4),group D(ScvO2＜80％ and Pl＜l.4).Hemodynamic parameters and tissue perfusion indexes at 2 hours(T2),4 hours(T4) and 6 hours(T6) after early resuscitation and troponin Ⅰ which indicated myocardial damage,on day 1 2 3 in ICU were recorded.Results (1)Lac clearance in group C was the quickest,which was 34.57％ (21.44％,44.20％),58.33％ (30.19％,70.79％),71.43％ (53.75％,82.79％) at T2,T4,T6 respectively.(2)The maximal incidence of myocardial damage was in group B(85.0％) and the lowest in group A (45.7％) on day 1 in ICU.Whereas on day 2,group C showed the lowest incidence of myocardial damage (29.3％) and group B the highest(70.0％).On day 3,the proportion of elevated troponin Ⅰ in group B was 70.0％,which was significantly higher than that of group B (29.3％,P＜0.008).(3)Logistic regression analysis suggested that the rate of Lac clearance at T4 in group B was related to the incidence of myocardial damage on day 2 and 3 in ICU.Conclusions The combination of PI and ScvO2 as a resuscitation target in patients with septic shock facilitates Lac clearance as the goal of resuscitation.The rate of arterial Lac clearance based on ScvO2 and PI is correlated with myocardial injury in patients with septic shock after early goal-directed therapy.

Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound,the examiner and interpreter of the image are critical care medicine physicians.The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes.With the idea of critical care medicine as the soul,it can integrate the above information and clinical information,bedside real-time diagnosis and titration treatment,and evaluate the therapeutic effect so as to improve the outcome.CUS is a traditional technique which is applied as a new application method.The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept,implementation and application of CUS.It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure.At the same time,the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications,and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS.Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group,based on the rich experience of clinical practice in critical care and research,combined with the essence of CUS,to learn the traditional ultrasonic essence,established the clinical application technical specifications of CUS,including in five parts:basic view and relevant indicators to obtain in CUS;basic norms for viscera organ assessment and special assessment;standardized processes and systematic inspection programs;examples of CUS applications;CUS training and the application of qualification certification.The establishment of applied technology standard is helpful for standardized training and clinical correct implementation.It is helpful for clinical evaluation and correct guidance treatment,and is also helpful for quality control and continuous improvement of CUS application.

Objective:To study the feasibility of the early diagnosis of chronic periodontitis using near-infrared diffuse correlation spectroscopy(DCS).Methods:30 subjects were inclded.The relative gingival blood flow(GBF) at the labial,mesial and distal healthy gingiva(the control) or the gingiva with periodontitis of maxillary anterior teeth was respectively measured by DCS before periodontal treatment,a week and a month after treatment.Results:The GBF of healthy gingiva group,gingivitis group and periodontitis group was 129.73 ± 10.70,95.51 ± 11.83 and 67.84 ± 13.05 respectively.Periodontal indexes were decreased and the relative GBF increased significantly 1 week and 1 month after treatment.Gingival index and sulcus bleeding index were respectively correlated to relative GBF(r =-0.902,r =-0.893).Conclusion:Near-infrared diffuse correlation spectroscopy can non-invasively detect the relative gingival blood flow in different stages of chronic periodontitis,it may be a method of early diagnosis of chronic periodontitis.
