Abstract:
Objective:To observe any effect of oscillating positive expiratory pressure training on the airway clearing ability of postoperative esophageal cancer patients after neoadjuvant chemotherapy.Methods:Forty postoperative esophageal cancer patients undergoing neoadjuvant chemotherapy were enrolled and randomized into a control group and an experimental group, each of 20. Both groups received conventional postoperative rehabilitation starting on the first postoperative day, while the experimental group additionally underwent oscillating positive expiratory pressure training (3 sets/day, 30 breaths/set) for five consecutive days. Peak cough flow was measured using a peak flow meter before and 1, 3 and 5 days after the operation. Forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), and peak expiratory flow (PEF) were also measured on the 5th day after the operation using spirometry. Any postoperative pulmonary complications were recorded.Results:On the 1st day after the operation, peak cough flow had decreased significantly in both groups compared to preoperative levels. However, it had increased significantly on days 3 and 5 in both groups, with the average increase in the experimental group significantly greater than in the control group. On day 5 the average FEV1, forced vital capacity and PEF in both groups were significantly lower than the preoperative values, while the experimental group demonstrated significantly higher average FEV1s (2.22±0.51L) and PEFs (5.09±1.26L/s) compared to the control group.Conclusions:Early postoperative oscillating positive expiratory pressure training can improve the peak cough flow and airway clearing ability of esophageal cancer patients after neoadjuvant chemotherapy, promoting the recovery of their lung function.
