Brief Summary

This study evaluates the effects of the breath stacking technique in patients after upper abdominal surgery. Half of the patients receive routine physical therapy associated with the Breath Stacking technique, while the other half will receive only routine physical therapy.

Detailed Description

This randomized controlled study aims to evaluate the effects of the Breath Stacking technique in patients undergoing upper abdominal surgery on clinical, physiological and cardiopulmonary variables. These individuals were randomized to compose the control group (CG) and the intervention group (GBS). The routine physical therapy was performed in both groups and in the GBS two daily sessions of up to 20 minutes of Breath Stacking technique were applied. To verify the effect of this intervention, before and after the protocol, patients underwent the following evaluations: algometry, cirtometry in the axillary line , umbilical line and the xiphoid process, ventilometry, spirometry and manovacuometry.

Conditions

Abdominal Surgery

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

Breath Stacking technique

The intervention group will receive routine physical therapy associated with the Breath Stacking technique in 2 daily sessions of up to 20 minutes.

The technique consists of an Instrument composed of a one-way valve coupled to a face mask to promote the accumulation of successive inspiratory volumes.

Group Type: EXPERIMENTAL

Breath Stacking

Intervention Type: DEVICE

The patients will perform the maneuver through successive inspiratory efforts for 20 s. Subsequently, the expiratory branch will be unobstructed to allow expiration. This maneuver will be repeated 5 times in each series, with intervals of 30 seconds between them. The technique will be performed with the trunk inclined 30º in relation to the horizontal plane, in 3 series, with interval of 2 min completing 15 min of therapy.

Routine physical therapy

The control group will receive only routine physical therapy. Routine physiotherapy consists of breathing exercises, using techniques bronchial hygiene and pulmonary reexpansion, and motor physiotherapy through exercise passive, active-assisted or active mobilization, stretching, training activities of daily living, positioning and removal of the bed and guidelines for post-discharge.

Group Type: NO_INTERVENTION

No interventions assigned to this group
