BLEEDING, POSTOPERATIVE COMPLICATIONS
Video‐assisted thoracoscopic surgery (VATS) is widely used because of small incisions, low bleeding, and quick patient recovery.Pressure‐controlled volume‐guaranteed ventilation (PCV‐VG) is a novel ventilation type, combining the advantages of both volume‐controlled ventilation (VCV) and pressure‐controlled ventilation (PCV).This study was conducted to explore the effects of PCV‐VG combined with direction‐changing PEEP on individualized PEEP determination and lung injury in patients with OLV. The results provide a new perspective on optimizing perioperative anesthesia techniques, reducing intraoperative lung injury, decreasing postoperative complications, and promoting early patient recovery.
