High-frequency jet ventilation (HFJV) allows for control of oxygenation in the open airways; nevertheless, there is a paucity of data to support its benefits versus cross-field ventilation.  Herein, we aimed to investigate the efficacy of HFJV on intraoperative oxygen saturation compared with cross-field ventilation in patients undergoing carinal surgeries.


 We conducted a retrospective analysis of 82 adults who underwent carinal resection and reconstruction (CRR) for benign or malignant diseases and received cross-field ventilation or HFJV at Shanghai Chest Hospital between January 2018 and September 2021.  Patients were excluded when they had emergency surgeries or critical airway stenosis requiring extracorporeal life support, or limited resection without the need for cross-field ventilation or HFJV.  Patients were classified into two groups based on the airway approach: cross-field ventilation group and HFJV group.  Thirty-two patients were included in the final analysis, with 22 patients in cross-field ventilation group and 10 patients in HFJV group.  The median (IQR) AUC of SpO2 below 90% was 21.92 (4.28, 54.48) min in cross-field ventilation group and 28.93 (10.78, 199.89) min in HFJV group.  The cumulative time of SpO2 <90% was 16.67 (4.46, 37.11) min in cross-field ventilation group and 19.32 (7.50, 121.24) min in HFJV group, without statistical difference between groups (P>0.05).  This retrospective case series demonstrates that HFJV can be adopted to maintain oxygenation in CRR, without the interruption of surgical procedure.
