[Can lung protective ventilation methods modify outcome?--A critical review].

Area of Science:

• Critical Care Medicine
• Pulmonary Medicine
• Mechanical Ventilation

Background:

• Mechanical ventilation can exacerbate lung injury through barotrauma, volutrauma, atelectrauma, and biotrauma.
• Lung-protective ventilation (LPV) strategies aim to mitigate ventilator-induced lung injury (VILI).
• Acute Respiratory Distress Syndrome (ARDS) is a primary indication for LPV.

Purpose of the Study:

• To evaluate the efficacy of lung-protective ventilation strategies in ARDS patients.
• To review various therapeutic measures supporting LPV.
• To determine the optimal approach for improving ARDS outcomes.

Main Methods:

• Analysis of experimental and clinical data on mechanical ventilation and VILI.
• Review of proposed therapeutic interventions for LPV in ARDS.
• Consideration of findings from large prospective randomized trials and observational studies.

Main Results:

• A lung-protective ventilation strategy, characterized by limited airway pressures and small tidal volumes, has demonstrated reduced mortality rates in ARDS.
• While several adjunctive therapies (e.g., prone positioning, ECMO) have been proposed, only prone positioning is widely adopted, and ECMO is reserved for select cases.
• No single adjunctive measure has definitively proven effective in randomized controlled trials.

Conclusions:

• Lung-protective ventilation is crucial for reducing mortality in ARDS.
• An optimized combination of therapeutic interventions, rather than isolated measures, shows promise for improving ARDS patient outcomes.
• Further research is needed to validate the effectiveness of combined therapeutic strategies in ARDS management.
