Drawing the Yongquan protocol into the different stages of the cardiopulmonary resuscitation sequence.
To introduce new applications into the ILCOR-cardiopulmonary resuscitation (CPR) "chain" sequence. ⋯ The Yongquan resuscitation manoeuver is a non-invasive, non-tiring, costless, and easy-to-apply procedure that provides a second chance when other options fail.

Used for over 3600 years, hypothermia, or targeted temperature management (TTM), remains an ill defined medical therapy. Currently, the strongest evidence for TTM in adults are for out-of-hospital ventricular tachycardia/ventricular fibrillation cardiac arrest, intracerebral pressure control, and normothermia in the neurocritical care population. ⋯ Despite ample experimental data, clinical evidence for stroke, refractory status epilepticus, hepatic encephalopathy, and intensive care unit is only at the safety and proof-of-concept stage. This review explores the deleterious nature of fever, the theoretical role of TTM in the critically ill, and summarizes the clinical evidence for TTM in adults.

ReviewPrognostic categorization of intensive care septic patients.
Sepsis is one of the leading worldwide causes of morbidity and mortality in critically-ill patients. Prediction of outcome in patients with sepsis requires repeated clinical interpretation of the patients' conditions, clinical assessment of tissue hypoxia and the use of severity scoring systems, because the prognostic categorization accuracy of severity scoring indices alone, is relatively poor. Generally, such categorization depends on the severity of the septic state, ranging from systemic inflammatory response to septic shock. ⋯ For mortality/survival prediction, it discusses the Acute Physiology and Chronic Health Evaluation scores, the Therapeutic Intervention Scoring System, the Simplified acute physiology score and the Mortality Probability Models. An ideal severity scoring system for prognostic categorization of patients with systemic sepsis is far from being reached. Scoring systems should be used with repeated clinical interpretation of the patients' conditions, and the assessment of tissue hypoxia in order to attain satisfactory discriminative performance and calibration power.

ReviewExtracorporeal cardiopulmonary resuscitation for adult cardiac arrest patients.
Cardiac arrest is a major cause of unexpected death in developed countries, and patients with cardiac arrest generally have a poor prognosis. Despite the use of conventional cardiopulmonary resuscitation (CPR), few patients could achieve return of spontaneous circulation (ROSC). Even if ROSC was achieved, some patients showed re-arrest and many survivors were unable to fully resume their former lifestyles because of severe neurological deficits. ⋯ Extracorporeal cardiopulmonary resuscitation (ECPR) has been reported to be superior to conventional CPR in in-hospital cardiac arrest patients. Veno- arterial ECMO is generally performed in emergency settings and it can be used to perform ECPR in patients with out-of-hospital cardiac arrest. Although there is no sufficient evidence to support the efficacy of ECPR in patients with out-of-hospital cardiac arrest, encouraging results have been obtained in small case series.

Hyperglycemia is common in critically ill patients and can be caused by various mechanisms, including nutrition, medications, and insufficient insulin. In the past, hyperglycemia was thought to be an adaptive response to stress, but hyperglycemia is no longer considered a benign condition in patients with critical illnesses. Indeed, hyperglycemia can increase morbidity and mortality in critically ill patients. ⋯ Higher glycemic variability may increase the mortality rate, even in patients with the same mean glucose level. Decreasing glucose variability is an important issue for glycemic control in critically ill patients. Continuous measurements with automatic closed-loop systems could be considered to ensure that blood glucose levels are controlled within a specific range and with minimal variability.
