Effects of IMT After Lung Cancer Surgery, a Randomized Controlled Trial

Effects of Inspiratory Muscle Training After Lung Cancer Surgery, a Randomized Controlled Trial 

This study is currently in the process of recruiting participants, and we won’t see the study completed until July 2014, 7 months after the final data has been collected for primary outcome measure.

The Responsible Party is Barbara C. Brocki, Aalborg University Hospital, with collaborators from University Hospital Orebro, Orebro University, Sweden and Katholieke Universiteit Leuven.

The purpose of the study is to evaluate the effects of postoperative inspiratory muscle training on the recovery of respiratory muscle strength in high risk patients referred for lung cancer surgery. Furthermore, to assess longitudinal changes in respiratory muscle strength, physical capacity and health-related quality of life after lung cancer surgery.

For the study the POWERbreathe K3 is being used for inspiratory muscle training (IMT).

The POWERbreathe K3 will be able to offer pressure threshold training with:

  • Advanced electronic variable load training
  • Auto-optimising IMT technology
  • Graphical history result (36 sessions)
  • Single breath test
  • Automatic warm-up and cool-down sessions

Primary Outcome Measure will be:

  • Change in inspiratory muscle strength [ Time Frame: Before surgery, 5.postoperative day, 2 weeks after surgery ]

Secondary Outcome Measures will be:

  • Change in expiratory muscle strength [ Time Frame: Before surgery, 5 th postoperative day and 2 weeks after surgery ]
  • Incidence of postoperative pulmonary complications [ Time Frame: 2 weeks after surgery ]

Other Outcome Measures can be found on the Clinical Trials website for the study: Effects of Inspiratory Muscle Training After Lung Cancer Surgery, a Randomized Controlled Trial

Detailed Description:

Advances in early detection and treatment improve life expectancy after surgery for lung cancer, but living with lung cancer is frequently associated with symptoms as dyspnoea, decreased physical capacity and fatigue several years after treatment. Lung cancer surgery is associated with a high incidence of postoperative pulmonary complications, having a negative impact on recovery. Although the causes of postoperative pulmonary complications are multifactorial, respiratory muscle dysfunction has been proposed to be associated with the development of postoperative pulmonary complications, explained by changes in respiratory muscle mechanics - and function due to surgery. There is scarcity of literature on the impact of respiratory muscle dysfunction on surgical and functional outcomes after lung cancer surgery.

Aims:

To describe longitudinal changes in respiratory muscle strength in patients undergoing lung cancer surgery and identify associations between respiratory muscle strength and functional capacity. Furthermore, to evaluate the effect of inspiratory muscle training on the recovery of respiratory muscle strength in high risk patients referred for lung cancer surgery.
