Active Cycle of Breathing Technique: A Respiratory Modality to Improve Perioperative Outcomes in Patients With Lung Cancer

BACKGROUND: Cancer and surgery put a physiologic and psychological burden on patients with lung cancer. The active cycle of breathing technique (ACBT) has been considered as an effective airway clearance method for patients with lung diseases. Its effectiveness on perioperative outcomes in patients with lung cancer warrants study. OBJECTIVES: This prospective study explored the effects of the ACBT on patients with lung cancer undergoing surgical resection. METHODS: Patients were randomly allocated to the intervention (N = 34) or control group (N = 34). The intervention group received the ACBT, and the control group received usual pre-/postoperative breathing exercises. Outcomes included dyspnea, exercise capacity, anxiety, depression, and postoperative pulmonary complications. Intention-to-treat analysis was also performed. FINDINGS: Dyspnea, anxiety, depression, and postoperative pulmonary complications were significantly improved at discharge for patients in the intervention group.
