Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Patients in the Fontan group were randomized into the Fontan Training Group (FTG) and Fontan Control Group. The FTG performed inspiratory muscle training with the Power Breth device with an initial load of 40% of the maximum inspiratory pressure obtained by measuring the maximum inspiratory pressure by manovacuometry. The training lasted 2 months. The patient was asked to perform the training every day with 3 series of 20 breaths. The training was monitored in person and remotely by videoconference; the load was increased gradually when it was perceived that it was already easy or reported by the child.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Control Group

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.

Group Type NO_INTERVENTION

No interventions assigned to this group

Fontan Training Group

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.

Fonta Control Group

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.
