The progress of critical care medicine in 2021 is still encouraging. The new international guideline for management of sepsis and septic shock came out after 4 years. Besides, a couple of preferable clinical evidences were released including restrictive blood transfusion strategy for patients with acute myocardial infarction, prevention of peripheral venous catheter infection, heparin inhalation and driving pressure setting in patients with acute respiratory distress syndrome (ARDS), lower oxygenation target for acute hypoxemic respiratory failure, low level positive end-expiratory pressure in non-ARDS patients with respiratory failure, light sedation or non-sedation strategy, biological phenotypes, as well machine learning in sepsis and ARDS. However, we also encounter negative results such as balanced solution during fluid resuscitation, hypothermia therapy after out-of-hospital cardiac arrest or traumatic brain injury, adrenomedullin-specific antibody adrecizumab therapy and coupled plasma filtration-adsorption (CPFA) therapy for patients with septic shock, extracorporeal carbon dioxide removal (ECCO2R) implementation in acute hypoxic respiratory failure, continuous infusion of hypertonic saline in patients with traumatic brain injury. Collectively, in the future, individualized diagnosis and management based on the principle of "wise choice" will become the daily practice scene for all intensivists.
