Cycle Ergometer Exercise in Phase I of Cardiac Rehabilitation After Cardiac Surgery

28 januari 2021 bijgewerkt door: Ada Clarice Gastaldi, University of Sao Paulo
The prevalence of heart diseases has increased significantly in recent years and it is a health public problem due to an increased risk of death by several reasons. A cardiac surgery is an alternative of treatment for critical injuries heart valves and coronaries arteries. Changes in respiratory system resulting from cardiac surgery are well established and include a reduced functional capacity due post-surgical pain, causing increased respiratory function and increased oxygen consumption . The exercises with the cycle ergometer in phase I of cardiac rehabilitation can improve peripheral muscle strength, functional capacity and perception of dyspnea when used postoperatively and there are speculations if an earlier carried out can contribute to a better postoperative evolution of patients, but these benefits in phase I of the Rehabilitation Cardiac are not well defined in the literature. Objective: To evaluate the exercises effects with ergometer cycle in the postoperative course of patients undergoing cardiac surgery. Method: Patients will be recruited the cardiac surgery service of Polyclinic Pato Branco in the city of Pato Branco in state of Paraná, of both sexes, appropriate for the inclusion criteria, which will be evaluated by pulmonary function tests (strength of respiratory muscles, submaximal exercise test, dyspnea scales, laboratories tests and radiological exam). All patients will be randomly assigned for one of two groups: the control group (Conventional treatment) and rehabilitation group (conventional treatment +cycle ergometer), for about 7 days at postoperative period. Patients will be reevaluated on the third postoperative day and at discharge. Clinical evolution data will be collected from the records and notes of the medical staff and monitoring physiotherapist.

Gedetailleerde beschrijving

The research will be a randomized controlled clinical trial. The study will be conducted at the Polyclinic Pato Branco, in the city of Pato Branco Parana - Brazil and this study already approved by the Ethics Committee Clinical Hospital and Faculty of Medicine, University of São Paulo and all participants sign the consent form informed. For the implementation of research wil be recruited patients heart surgery who fit the inclusion criteria and do not show any characteristics of the exclusion criteria, which agree to participate and sign the consent form free and informed. The equipment and tests are already included in routine admissions of patients, approved by the hospital and the Brazilian Public Health System (SUS).

Primaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
Change of six-minute walk test (6MMWT) distance
Tijdsspanne: Before surgery ,third and seventh postoperative day
The six-minute walk test will be conducted with monitoring blood pressure, HR, RR and SpO2 in a hall plan, with distances previously marked. The patient will be accompanied by the researcher and encouraged by constant verbal stimulation, walking as fast as possible, if the patient stop walking the timer will keep triggered. Will use the oximeter with the sensor on the third finger of the right hand, and a certain reading after the signal stabilization and at the same time we get the heart rate. Will be used to calculate the expected value, and reference to distance in the 6MWT, the equations proposed by Enright and Sherrill (1998) determining the percentage of predicted for each test performed by patient.
Before surgery ,third and seventh postoperative day

Tijdsspanne
Change of spirometric values
Tijdsspanne: Before surgery ,third and seventh postoperative day
Spirometry will be performed according to criteria of the American Thoracic Society and the Brazilian Consensus Spirometry. Values will be observed from CVF, VEF1 e PEF.
Before surgery ,third and seventh postoperative day

Maatregel Beschrijving
Tijdsspanne
Change of respiratory muscle strength - Mouth pressure measurements
Tijdsspanne: Before surgery ,third and seventh postoperative day
Manovacuometry will be performed with the patient seated with nasal clip, the display scale with intervals of 4 cmH2O and variation +/- 120 cmH2O. The highest value obtained during the two maneuvers will be compared to the table described by Neder et al (1999), which predicts expected values for the Brazilian population according to gender and age.
Before surgery ,third and seventh postoperative day
Change of perceived dyspnea
Tijdsspanne: Before surgery ,third and seventh postoperative day
The perceived effort is used the Borg Scale modified scored from 0 to 10. And dyspnea scale will be scored from 0 to 4 according to the intensity of dyspnea and is based on used the scale of the Medical Research Council (MRC).
Before surgery ,third and seventh postoperative day
Change of body mass index
Tijdsspanne: Before surgery and postoperative seventh day
The BMI will be calculated using the classical formula: BMI = current weight (kg) / A2 (m). The following lower limits of normal were considered: BMI <21 for age group 35-44 years; <22 for 45-54 years; <23 for 55 -64 years and <24 to 65 above years.

Tijdsspanne: Before surgery ,third and seventh posoperative day
Cirtometry will be held in myocardial revascularization of patients who use the saphenous and waist hip will be performed in all patients. Will be used a tape measure.
Before surgery ,third and seventh posoperative day
Change of peripheral muscle strength
Tijdsspanne: Before surgery ,third and seventh postoperative day
The peripheral muscle strength assessment test will be the end of the test the foot, the patient will be instructed to stay barefoot with his right hand resting on the front wall and with a semi elbow flexion to aid maintenance balance. Prior to testing, the participant will be oriented make a plantar flexion to the point of support of the joints metatarsophalangeal and this time will be marked by the examiner through a mark on the wall and the patient will be informed that should reach the one marked point. The test itself consisted of time, in seconds, the time it takes to perform five push-ups as plantar soon as possible.
Before surgery ,third and seventh postoperative day
Change in cortisol levels
Tijdsspanne: Before surgery ,third and seventh postoperative day
Laboratory evaluation will be performed by laboratory staff of hospital with a blood sample from the patient, which will be assessed the cortisol levels .
Before surgery ,third and seventh postoperative day
change of radiological assessment
Tijdsspanne: Before surgery ,third and seventh postoperative day
Radiological assessment will be held the day before the surgery, the third post-operative and post-operative seventh, the clinic Radiology Southwest - Pato Branco - Paraná to assess complications lung from surgery.
Before surgery ,third and seventh postoperative day
Adherence evaluation
Tijdsspanne: Third and seventh postoperative day
The questionnaire will be administered at the end of the first contact of the patient the exercises with the cycle ergometer to assess adherence running a differential exercise during your surgical recovery.
