Protective ventilation strategies are crucial for obese surgical patients. Recommendations include low tidal volumes, lung recruitment with PEEP, and judicious oxygen use to prevent pulmonary complications.
Area of Science:
- Anesthesiology
- Critical Care Medicine
- Pulmonology
Background:
- Obesity presents unique challenges for mechanical ventilation in surgical patients.
- Increased adiposity, respiratory comorbidities, and postoperative risks necessitate specialized ventilation strategies.
Purpose of the Study:
- To review and recommend perioperative protective ventilation strategies for surgical patients with obesity.
- To address challenges in mechanical ventilation due to obesity and surgical factors.
Main Methods:
- Literature review summarizing existing evidence on perioperative ventilation in obese patients.
- Analysis of recommendations for tidal volume, PEEP, recruitment maneuvers, and oxygen use.
Main Results:
- Low tidal volumes (8 mL/kg predicted body weight) are recommended to prevent volutrauma.
- Lung recruitment using PEEP (8-15 cmH2O) and maneuvers are advised to combat atelectasis.
- Judicious oxygen use (<0.8 FiO2) is suggested to prevent hypoxemia and atelectasis.
Conclusions:
- Obesity complicates protective ventilation, especially during one-lung ventilation.
- Postoperative strategies should focus on preventing hypoventilation, atelectasis, and hypoxemia.
- Further research is needed to optimize strategies and assess perioperative outcomes.
