Details and patient eligibility

About

This study will assess physical and respiratory capacity, diaphragmatic mobility and quality of life. Healthy children and children who have undergone Fontan surgery will participate. Some children in the late postoperative period of Fontan surgery will be randomized to a group of inspiratory muscle training that will last for 2 months. Children after Fontan surgery will be evaluated twice, once at the beginning and again after two months of follow-up.

Full description

This study aims to evaluate physical capacity through cardiopulmonary testing, submaximal physical capacity testing by the 6-minute walk test, respiratory capacity by spirometry, respiratory muscle strength by manovacuometry, diaphragmatic mobility by ultrasound, quality of life by the AUQEI questionnaire. There are three groups, a healthy control group, a Fontan control group and a Fontan intervention group. The intervention will be done by respiratory muscle training using the Power Breath device.

45 participants in 3 patient groups

Control Group

No Intervention group

Description:

The control group consisted of 18 healthy children. These children underwent cardiopulmonary testing, spirometry, chest ultrasound to assess the diaphragm, 6-minute walk test, respiratory muscle strength and quality of life. These tests were performed to assess the results of these tests in patients without previous illnesses.

Fontan Training Group

Active Comparator group

Description:

The Fonta training group consisted of 14 children in the late postoperative period of Fontan surgery. These children underwent cardiopulmonary testing, spirometry, chest ultrasound to assess the diaphragm, 6-minute walk test, respiratory muscle strength and quality of life. These tests were performed at the initial stage and after two months of inspiratory muscle training to assess the results of these in postoperative patients and what changes the training could bring. The training was performed with the Power Breath device, the carda was quantified at 40% of the force exerted at maximum inspiratory pressure by manovacuometry. The patient was asked to perform 3 sets of 20 repetitions twice over the course of 7 days of the week. Monitoring was done in person and virtually, and the carda was increased according to the evaluator's perception of the ease of the exercise or if the patient reported it to be easy. The training lasted 2 months.

Other: Fontan Training Group

Fonta Control Group

No Intervention group

Description:

The Fonta Control Group consisted of 13 children in the late postoperative period of Fontan surgery. These children underwent cardiopulmonary testing, spirometry, chest ultrasound to assess the diaphragm, 6-minute walk test, respiratory muscle strength and quality of life. These tests were performed at the initial stage and after two months to assess the results of these tests in postoperative patients and whether there was any normal behavior.
