Recent studies have led to a better understanding of mechanical ventilation strategies in patients with septic shock, particularly in the use of neuromuscular blocking agents, PEEP, and recruitment maneuvers. The role of lung protective ventilation in patients with healthy lungs still needs further refinement, and the potential detrimental effects of spontaneous breathing in patients with acute respiratory distress syndrome are increasingly recognized.
Purpose of review The aim of this study was to review the most recent literature on mechanical ventilation strategies in patients with septic shock. Recent findings Indirect clinical trial evidence has refined the use of neuromuscular blocking agents, positive end-expiratory pressure (PEEP) and recruitment manoeuvres in septic shock patients with acute respiratory distress syndrome. Weaning strategies and devices have also been recently evaluated. The role of lung protective ventilation in patients with healthy lungs, while recognized, still needs to be further refined. The possible detrimental effects of spontaneous breathing in patients who develop acute respiratory distress syndrome is increasingly recognized, but clinical trial evidence is still lacking to confirm this hypothesis. A new concept of lung and diaphragm protective is emerging in the critical care literature, but its application will need a complex intervention implementation approach to allow adequate scrutiny of this concept and uptake by clinicians. Many advances in the management of the mechanically ventilated patient with sepsis and septic shock have occurred in recent years, but clinical trial evidence is still necessary to translate new hypotheses to the bedside and find the right balance between benefits and risks of these new strategies.
