Individualized PEEP Improves Lung and Brain Outcomes
- A study published in BMC Cancer in 2025 investigates individualized positive end-expiratory pressure (PEEP) settings in patients undergoing rectal cancer surgery.
- Research explores tailored PEEP's effects on pulmonary function, cerebral blood flow, and cognitive recovery post-surgery.
- The study enrolled 100 patients, comparing PEEP strategies based on driving pressure versus pulmonary dynamic compliance.
- Lung ultrasound scoring reflected better alveolar stability with compliance-based PEEP settings compared to driving pressure-focused ones.
- Cdyn group exhibited lower driving pressures, indicating reduced lung injury risks and potential postoperative respiratory benefits.
- Despite fluctuations in airway pressures, compliance-driven PEEP showed a complex impact on ventilation and oxygen delivery.
- Lower cerebral perfusion in the Cdyn group was associated with improved cognitive function postoperatively.
- The study suggests that personalized PEEP strategies may shield the brain from perioperative insults and improve patient outcomes.
- No baseline differences between groups emphasize the significance of compliance-guided PEEP in influencing study outcomes.
- This research highlights the potential of tailored ventilation strategies to enhance perioperative care and patient outcomes in complex surgeries.
