By Hao M, Zhang B, Han Y and 3 others.
Abstract
Aim
To evaluate the association between Cdyn-guided PEEP during one-lung ventilation (OLV) and nursing activities in the post-anaesthesia care unit (PACU) among infants undergoing thoracoscopic surgery under general anaesthesia: DESIGN: Retrospective observational cohort study.
Methods
A retrospective analysis was conducted on clinical data from infants with congenital pulmonary airway malformation (CPAM) who underwent thoracoscopic lobectomy at a Children's Hospital Affiliated to Shandong University between January 2022 and February 2025. Patients were classified according to the recorded intraoperative PEEP strategy actually delivered during OLV: Group P was managed with Cdyn-guided individualized PEEP; Group C was managed with fixed PEEP of 5 cmH2O. The primary outcome was PACU Nursing Activities Score (NAS). Baseline clinical characteristics, postoperative outcomes (incidence of delirium, pain scores), PACU observation time, and adverse events were compared between the two groups.
