Study population: Women undergoing lipoabdominoplasty who meet the eligibility criteria for the search.

Brief summary: Background: The lipoabdominoplasty can lead to respiratory complications in the postoperative period becoming critical early clinical and functional evaluation of respiratory muscles, seeking to direct a more effective treatment, which can result in shorter hospital stays and lower spending on health in patients undergoing such procedures. Objective: To evaluate the correlation of regional distribution of ventilation system with thoracoabdominal diaphragmatic mobility in women undergoing surgery lipoabdominoplasty comparing preoperative, 10 ° and 30 ° DPO DPO. Methods: This is a prospective cohort study, which will be evaluated 30 women aged 25 to 55 years undergoing lipoabdominoplasty surgery without respiratory or prior cardiac comorbidities and body mass index (BMI) ≤ 30 kg / cm2. women smokers are deleted and / or a history of smoking more than 10 years and unable to understand the commands to perform the proposed methods. For evaluation of diaphragmatic mobility will be used high-resolution ultrasound with convex 3.5 MHz transducer. The evaluation of the regional distribution of ventilation thoracoabdominal system will be made using the optoelectronic plethysmograph (POE). The strength of the inspiratory and expiratory muscles is measured through a digital manometer connected to a nozzle with an orifice of 2 mm to reduce the closing pressure of the glottis. A portable spirometer is used for assessment of pulmonary function and evaluation of dyspnea will be used modified Borg scale. The data will be evaluated in the preoperative period, 10 days and 30 days postoperatively. Hypotheses: Patients undergoing surgery lipoabdominoplasty have decreased diaphragmatic mobility, strength and respiratory function, in addition to presenting changes in the pattern of regional ventilation distribution in torocoabdominal system in the postoperative period when compared to the preconditions surgery.

Detailed description: Introduction:

The lipoabdominoplasty can lead to respiratory complications in the postoperative period becoming critical early clinical and functional evaluation of respiratory muscles, seeking to direct a more effective treatment, which can result in shorter hospital stays and lower spending on health in patients subjected to this type of procedure.

hypotheses: Patients undergoing lipoabdominoplasty surgery with muscular plication, have decreased diaphragmatic mobility, strength and respiratory function, in addition to presenting changes in the regional distribution pattern of ventilation in torocoabdominal system in the postoperative period when compared to the preconditions surgery .

Goal:

To evaluate the correlation of regional distribution of ventilation system with thoracoabdominal diaphragmatic mobility in women undergoing surgery lipoabdominoplasty comparing preoperative, 10 ° and 30 ° DPO DPO.

Hypothesis:

Patients undergoing surgery lipoabdominoplasty have decreased diaphragmatic mobility, strength and respiratory function, in addition to presenting changes in the pattern of regional ventilation distribution in torocoabdominal system in the postoperative period when compared to the preconditions surgery.

Materials and methods:

This is a prospective cohort study, which will be evaluated 30 women between 30 and 50 years underwent surgery lipoabdominoplasty without respiratory or prior cardiac comorbidities and body mass index (BMI) ≤ 30 kg / cm2. women smokers are deleted and / or a history of smoking greater than 10 years, FEV1 \<80% predicted, FEV1 / FVC \<70% of predicted and unable to understand the commands to perform the proposed methods. For evaluation of diaphragmatic mobility and thickness will be used high-resolution ultrasound with a convex transducer of 3.5 MHz and 7.5 MHz linear transducer, respectively. The assessment of the regional distribution of ventilation thoracoabdominal system will be made using the optoelectronic plethysmograph (POE). The strength of the inspiratory and expiratory muscles is measured through a digital manometer connected to a nozzle with an orifice of 2 mm to reduce the closing pressure of the glottis. A portable spirometer is used for assessment of pulmonary function and evaluation of dyspnea will be used modified Borg scale. The data will be evaluated in the preoperative period, 10 days and 30 days postoperatively.

Eligibility criteria: Inclusion Criteria:

* women will be included between 25 and 55 years underwent surgery lipoabdominoplasty without respiratory or prior cardiac comorbidities and body mass index (BMI) ≤ 30 kg / cm2.

Exclusion Criteria:

* women smokers will be deleted and / or a history of smoking more than 10 years; FEV1 \<80% predicted and FEV1 / FVC \<70% of predicted; unable to understand the commands to perform the proposed methods.
