Effect of high-frequency chest wall oscillation on pulmonary function after pulmonary lobectomy for non-small cell lung cancer
Critical Care Medicine, 08/21/2012
Park H et al. – High–frequency chest wall oscillation therapy after pulmonary lobectomy resulted in significantly improved immediate postoperative pulmonary function recovery compared to conventional physiotherapy, without any significant adverse effects. These results suggest that high–frequency chest wall oscillation therapy may be a valuable tool in the postoperative care of non–small cell lung cancer patients with lobectomy.Methods
- Sixty–six patients were enrolled in the study.
- Patients in the control group had routine postoperative percussive chest physiotherapy four times a day.
- Participants in the high–frequency chest wall oscillation group received three sessions of high–frequency chest wall oscillation treatment every 8hrs for 15mins starting 4hrs after surgery.
- All the treatments and measurements were performed by randomly assigned nursing staff who had received standardized education for respiratory care and who were not aware of the details of the study.
- The primary outcome was postoperative change of forced expiratory volume for 1sec, and secondary outcomes were changes in arterial oxygen partial pressure and saturation.
- Safety outcomes and pain scores were also investigated.
- Patients in the high–frequency chest wall oscillation group experienced significantly improved recovery of pulmonary function as assessed by forced expiratory volume for 1sec on the third and fifth postoperative days (p=.03) and improved oxygenation on the first postoperative day (p<.01).
- There were no significant differences in pain score or analgesic requirements.
