Outcome Measures

Primary Outcomes (3)

  • Maximum static respiratory pressures

    This measurement was made at mouth level by using a properly calibrated manovacuometer (GERAR ®, São Paulo, Brazil), with graduation ranging from 0 to ± 300 cmH2O, connected to a rigid plastic tube.

    post-operative days 2, 7, 14, and 30

  • Inspiratory muscular endurance test

    This measurement was performed by using the Threshold® IMT device (Health Scan Products, USA), at 80% maximal inspiratory pressure, in sitting position.

    post-operative days 2, 7, 14, and 30.

  • Spirometric measurements

    Spirometry was performed according to norms of the American Thoracic Society (ATS) (1994)19 by using a previously calibrated spirometer (Respiradyne II Plus®, Sherwood Medical, St. Louis, USA).

    post-operative days 2, 7, 14, and 30.

Secondary Outcomes (3)

  • Maximum static respiratory pressures

    post-operative days 2, 7, 14, and 30

  • Inspiratory muscular endurance test

    post-operative days 2, 7, 14, and 30

  • Spirometric measurements

    post-operative days 2, 7, 14, and 30.

Study Arms (2)

control group

PLACEBO COMPARATOR

In placebo muscular training group the respiratory exercise was used a linear pressure resistance device (Threshold ® IMT - Health Scan Products; USA) no load.

Device: control group

trained group

ACTIVE COMPARATOR

In trained group the respiratory exercise used a linear pressure resistance device (Threshold ® IMT - Health Scan Products; USA)the load was initially set at 40% of the maximal inspiratory pressure.

Device: inspiratory muscle training

Interventions

This daily respiratory exercise was performed from the 2nd day following surgery by using a linear pressure resistance device (Threshold ® IMT - Health Scan Products; USA)was initially set at 40% of the maximal inspiratory pressure, obtained in the 2nd post-operative day, being adjusted to every new maximal inspiratory pressure measurement.

Also known as: respiratory training
trained group

In placebo muscular training the daily respiratory exercise was performed from the 2nd day following surgery by using a linear pressure resistance device (Threshold ® IMT - Health Scan Products; USA)no load until the 30th post-operative day.
