Implication

A randomized controlled trial demonstrates EIT-guided PEEP improves lung scores in metabolic bariatric surgery patients, indicating better respiratory function.

Key Points

Investigate the impact of EIT-guided personalized PEEP on early postoperative lung aeration in patients undergoing metabolic bariatric surgery.
Single-center, randomized controlled trial
Enrolled 120 patients scheduled for metabolic bariatric surgery
Divided participants into EIT-guided PEEP group and standard PEEP group (5 cmH2O)
Measured lung ultrasound scores preoperatively and post-extubation
Analyzed postoperative oxygenation index and respiratory mechanics
EIT-guided PEEP group showed a greater improvement in lung ultrasound score (1.68 vs 1.25)
Higher postoperative oxygenation index in EIT group (407.58 mmHg vs 393.15 mmHg)
Increase in dynamic lung compliance in the EIT group
No significant differences in postoperative pulmonary complications or hemodynamic safety parameters
