[The relationship between arterial blood lactate clearance, prognosis and myocardial damage in patients with septic shock after early goal-directed therapy].
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(ScvO(2))>70% and urine volume (UO) >0.5ml·kg(-1)·h(-1) and arterial blood lactate (Lac) >2 mmoL/L. ⋯ 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).⑶Logistic 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 ScvO(2) 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 ScvO(2) and PI is correlated with myocardial injury in patients with septic shock after early goal-directed therapy.

[The clinical significance of microcirculation and oxygen metabolism evaluation in acute kidney injury assessment in patients with septic shock after resuscitation].
Objective: To evaluate the value of microcirculation and oxygen metabolism evaluation (MicrOME) in acute kidney injury(AKI) evaluation in patients with septic shock after resuscitation. Methods: Consecutive patients with septic shock after resuscitation and mechanical ventilation were enrolled from October 2016 to February 2017 in ICU at Peking Union Medical College Hospital. Patients were divided into 3 groups based on 10 min transcutaneous oxygen challenge test transcutaneous partial pressure of oxygen(PtcO(2))and venoarterial pressure of carbon dioxide difference (Pv-aCO(2)) /arteriovenous O(2) content difference (Ca-vO(2)) by blood gas analysis, i.e. group A [ΔPtcO(2)>66 mmHg(1 mmHg=0.133 kPa) and Pv-aCO(2)/Ca-vO(2)≤1.23], group B (ΔPtcO(2)≤66 mmHg), group C (ΔPtcO(2)>66 mmHg and Pv-aCO(2)/Ca-vO(2)>1.23). ⋯ The cutoff value of Pv-aCO(2)/Ca-vO(2) was equal or more than 2.20 for predicting progression of AKI, resulting in a sensitivity of 85.7% and a specificity of 73.8%. Conclusion: MicrOME is a significant parameter to predict the progression of AKI in patients with septic shock after resuscitation. Pv-aCO(2)/Ca-vO(2) is also a good predictive factor.

[Investigation of doctors' and nurses' perceptions and implementation of delirium management in intensive care unit].
Objective: To investigate doctors' and nurses' perceptions and implementation of delirium management in intensive care unit. Methods: A total of 197 doctors and nurses in 2 general ICUs and 3 special ICUs at Peking Union Medical College Hospital finished a self-designed questionnaire of delirium management. Results: There were 47 males and 150 females, 43 doctors and 154 nurses who participated in the survey. ⋯ Doctors and nurses from different ICUs had significant discrepancy in the implementation of "delirium assessment" (P< 0.05). Conclusions: The ICU staff should improve the perceptions and the implementation of delirium management,especially in special ICUs. Delirium management should be included as a routine care in ICU to improve patients' outcome.

[Experts consensus on the management of the right heart function in critically ill patients].
To establish the experts consensus on the right heart function management in critically ill patients. The panel of consensus was composed of 30 experts in critical care medicine who are all members of Critical Hemodynamic Therapy Collaboration Group (CHTC Group). Each statement was assessed based on the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) principle. ⋯ The early and prominent manifestation of non-focal cardiac tamponade is right ventricular diastolic involvement, the elevated right atrial pressure should be noticed. (19) The effect of increased intrathoracic pressure on right heart diastolic function should be valued. (20) Ttricuspid annular plane systolic excursion (TAPSE) is an important parameter that reflects right ventricular systolic function, and it is recommended as a general indicator of critically ill patient. (21) Circulation management with right heart protection as the core strategy is the key point of the treatment of acute respiratory distress syndrome. (22) Right heart function involvement after cardiac surgery is very common and should be highly valued. (23) Right ventricular dysfunction should not be considered as a routine excuse for maintaining higher central venous pressure. (24) When left ventricular dilation, attention should be paid to the effect of left ventricle on right ventricular diastolic function. (25) The impact of left ventricular function should be excluded when the contractility of the right ventricle is decreased. (26) When the right heart load increases acutely, the shunt between the left and right heart should be monitored. (27) Attention should be paid to the increase of central venous pressure caused by right ventricular dysfunction and its influence on microcirculation blood flow. (28) When the vasoactive drugs was used to reduce the pressure of pulmonary circulation, different effects on pulmonary and systemic circulation should be evaluated. (29) Right atrial pressure is an important factor affecting venous return. Attention should be paid to the influence of the pressure composition of the right atrium on the venous return. (30) Attention should be paid to the role of the right ventricle in the acute pulmonary edema. (31) Monitoring the difference between the mean systemic filling pressure and the right atrial pressure is helpful to determine whether the infusion increases the venous return. (32) Venous return resistance is often considered to be a insignificant factor that affects venous return, but attention should be paid to the effect of the specific pathophysiological status, such as intrathoracic hypertension, intra-abdominal hypertension and so on. Consensus can promote right heart function management in critically ill patients, optimize hemodynamic therapy, and even affect prognosis.

Observational Study[The impact of goal directed analgesia on mechanical ventilated patients's outcomes in intensive care unit: a clinical observational study].
To investigate the impact of goal directed analgesia on the outcome of patients with mechanical ventilation in intensive care unit. A total of 126 patients who needed mechanical ventilation were recruited. With a method of before and after paired comparison, they were divided into two group: (1) analgesia with empirical administration or control group; (2) goal directed analgesia based on critical-care pain observation tool (CPOT). ⋯ The mean ventilator duration was significantly shortened from (168.49±11.41) h to (142.38±13.24) h(P<0.05). ICU length of stay was significantly shortened from (23.64±9.26) d to (19.63±8.46) d(P<0.05). Due to the mild sedation, patients receiving goal directed analgesia report less delirium, less ventilation time and shorter ICU length of stay, suggesting that the general outcome is improved.
