[A Chinese consensus statement on the clinical application of transesophageal echocardiography for critical care (2019)].
Transesophageal echocardiography(TEE) is valuable in intensive care unit (ICU) because its application meets the requirements of diagnosis and treatment of critically ill patients. However, the current application has not fully adapted to the specialty of critical care. TEE could be more valuablein ICU when used with a new way that under the guidance of the theory of critical care and embedded into the treatment workflow. ⋯ The consensus of Chinese experts on clinical application of TEECC (2019) were 33 in total, of whichthe main items were as follows: (1) TEECC is a significant means, which is expanded and improved from the traditional transesophageal echocardiography according to characteristics of critically ill patients and is applied in ICU based on critically clinical scenarios and requirements by the critical care physician, to promote visualized, refined and precisely management of critically ill patients.(2) TEE possesses distinctive superiority in implementation in ICU. It has characteristics of images with good quality, operations with good stability and low-dependent of operators, monitoring with continuity, and visualization with all-dimensional and detail of heart and blood vessels.(3)As a means of refined monitoring that could resulted in precise diagnosis and treatment, TEECC expands the dimension of intensive monitoring and improves the performance of critical care. (4) Indications of TEECC application include clinical etiological searching and invasive procedures guiding when it acted as a traditional role; and also refined hemodynamic monitoring based on critical care rationale and over-all management under specific critical clinical scenarios. (5) TEE and TTE assessments are complementary; they are not alternative. Integrated assessment of TTE and TEE is required under many critical clinical scenarios.(6) TEE should be a necessary configuration in ICU. (7) All-round and significant information regarding to the mechanism of acute circulatory disorders can be provided by TEECC; it is a non-substitutable means of identifying the causes of shock under some special clinical scenarios. (8) Focal extracardiac hematoma can be accurately and rapidly detected by TEE in patients with open-thoracic cardiac surgery or severe chest trauma when highly suspected pericardial tamponade.(9) The priority of pathophysiologic mechanism of septic shock can be rapidly and accurately identified by TEE; even if its pathophysiological changes are complex, including hypovolemia and/or vasospasm and/or left and right heart dysfunction. (10) Causes of hemodynamic disorders can be rapidly and qualitatively evaluated so that the orientation of treatment can be clarified by TEECC. (11) A full range of quantitative indicators for refined hemodynamic management in critically ill patients can be provided by TEECC. (12) TEECC helps to accurately assess volume status and predict fluid responsiveness.(13) TEECC is specially suitable for accurate quantitative assessment of cardiac function.(14) Mini TEE provides long-term continuous hemodynamic monitoring. (15) Standard views are easy to be acquired by TEECC, which is a premise for accurate and repeatable measurements, and a guarantee for assessment of effect and risk of therapy. (16) Compared with invasive hemodynamic monitoring, TEECC is minimally invasive, with low infection risk and high safety.(17) In patients with acute cor pulmonale (ACP) under condition of right ventricular dysfunction and low cardiac output, TEECC is a key tool for assessment. (18) TEECC should be implemented actively when suspicious of left to right shunt in critically ill patients who occurred hypotension that hard to explain the cause. (19) TEECC should be implemented actively when suspicious of right to left shunt in critically ill patients who occurred hypoxemia that hard to explain the cause. (20) TEECC is preferred in hemodynamics monitoring under prone position of ventilated patients.(21) TEECC is an imperative means to achieve over-all management of extracorporeal membrane oxygenation (ECMO) therapy, especially for all-round hemodynamic monitoring. (22) Three basic views is recommended to be used to simplify TEE assessment during cardiac arrest so that reversible causes could be identified, and resuscitation could be guided. (23) The flow related echodynamic evaluation (TEECC-FREE) workflow is preferred in refined hemodynamics monitoring and therapy. (24) Simple workflow of TEECC could be implemented in special critical clinical scenarios. (25) Application of TEECC is highly secure; however, impairments of procedure should also be alert by operators. (26) Pitfalls in application of TEE should be paid attention to by the critical care physician. (27) Timely and rationally application of TEECC is in favor of diagnosis and treatment of critically ill patients and may improve the prognosis.

[A reevaluation of diagnostic efficacy of International Society of Thrombosis and Haemostasis and Japanese Association for Acute Medicine criteria for the diagnosis of sepsis disseminated intravascular coagulation].
Objective: To reevaluate the diagnostic efficacy of International Society of Thrombosis and Haemostasis (ISTH) and Japanese Association for Acute Medicine (JAAM) criteria for sepsis disseminated intravascular coagulation (DIC). Methods: A total of 769 patients diagnosed as sepsis were enrolled in our study. Blood samples were collected within the first hour in ICU and the index of coagulation was detected. ⋯ Conclusions: According to the ISTH and JAAM diagnostic criteria, the diagnostic efficacy of PT and PLT is relatively high, which is associated with the severity of DIC. D-dimer and FDP have the high sensitivity but the specificity is poor. The diagnostic specificity of Fib is good, yet with low sensitivity and poor overall efficacy.

[The value of renal resistance index and urine oxygen pressure for prediction of acute kidney injury in patients with septic shock].
Objective: To explore the value of renal resistance index (RI) and urine oxygen pressure for early prediction of acute kidney injury (AKI) in patients with septic shock. Methods: Patients with septic shock were enrolled from August 2018 to November 2018 in intensive care unit (ICU) at Peking Union Medical College Hospital. Subjects' general information and AKI characteristics were assessed. ⋯ Conclusion: High RI and low urine oxygen pressure are independent risk factors for the development of AKI in patients with septic shock. The predictive cut-off values are 0.70 for RI and 48 mmHg for urine oxygen pressure. Combination of RI and urine oxygen pressure has a practical predictive value for AKI in patients with septic shock.

[Experts consensus on the management of delirium in critically ill patients].
To establish the experts consensus on the management of delirium in critically ill patients. A special committee was set up by 15 experts from the Chinese Critical Hypothermia-Sedation Therapy Study Group. Each statement was assessed based on the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) principle. ⋯ Bedside electroencephalogram monitoring should be used in the ICU if conditions warrant. (17) Pay attention to differential diagnosis of delirium and dementia/depression. (18) Pay attention to the role of rapid delirium screening method in delirium management. (19) Assessment of the severity of delirium is an essential part of the diagnosis of delirium. (20) The key to the management of delirium is etiological treatment. (21) Improving environmental factors and making patient comfort can help reduce delirium. (22) Early exercise can reduce the incidence of delirium and shorten the duration of delirium. (23) Communication with patients should be emphasized and strengthened. Family members participation can help reduce the incidence of delirium and promote the recovery of delirium. (24) Pay attention to the role of sleep management in the prevention and treatment of delirium. (25) Dexmedetomidine can shorten the duration of hyperactive delirium or prevent delirium. (26) When using antipsychotics to treat delirium, we should be alert to its effect on the heart rhythm. (27) Delirium management should pay attention to brain functional exercise. (28) Compared with non-critically illness related delirium, the relief of critically illness related delirium will not accomplished at one stroke. (29) Multiple management strategies such as ABCDEF, eCASH and ESCAPE are helpful to prevent and treat delirium and improve the prognosis of critically ill patients. (30) Shortening the duration of delirium can reduce the occurrence of long-term cognitive impairment. (31) Multidisciplinary cooperation and continuous quality improvement can improve delirium management. Consensus can promote delirium management in critically ill patients, optimize analgesia and sedation therapy, and even affect prognosis.

[Risk factors and prognoses analysis of new-onset atrial fibrillation in patients with acute myocardial infarction].
Objective: To explore the risk factors and prognoses of new-onset atrial fibrillation (NOAF) in patients with acute myocardial infarction (AMI). Methods: A total of 468 patients with AMI were admitted into Beijing Anzhen Hospital for emergency pereutaneous coronary intervention (PCI). According to the NOAF occurred during hospitalization, the patients were divided into two groups: the NOAF (n=37) group and the non-NOAF (n=431) group. ⋯ The in-hospital mortality (8.1% vs 1.4% P=0.004) and the incidence of in-hospital MACCE (37.8% vs. 7.7%, P<0.001) in the NOAF group were significantly higher than those in the non-NOAF group. Logistic multivariate regression analyses showed that age (HR 1.083, 95%CI 1.028-1.141, P=0.003), CRP (HR 1.116, 95%CI 1.049-1.187, P=0.001), NT-pro-BNP (HR 1.463, 95%CI 1.001-4.064, P=0.001) and no-reflow (HR 4.388, 95%CI 1.006-19.144, P=0.049) were independent predictors of NOAF after AMI. Conclusions: Age, elevated levels of CRP, NT-pro-BNP, and the absence of no-reflow are risk factors for incident NOAF in patients with AMI in hospital.
