SUMMARY:

Introduction: Congenital heart defects represent the most common congenital anomalies and frequently require surgical intervention within the first year of life. In the postoperative period, infants present a high risk of respiratory complications resulting from surgical trauma and extracorporeal circulation, which can compromise respiratory mechanics and prolong ventilatory support. Although respiratory physiotherapy is widely used in this context, evidence on the isolated effects of specific techniques is still limited. Objective: To evaluate the feasibility of conducting a clinical trial comparing the Thoracoabdominal Rebalancing Method (RTA) and Assisted Autogenic Drainage (AAD) in infants in the postoperative period following surgery for congenital heart disease. Method: Feasibility clinical trial, controlled and randomized with Public and Patient Involvement (PPE). The sample will consist of 20 infants, randomly allocated into two intervention groups (RTA or AAD), receiving a single 10-minute session of the proposed technique. The feasibility outcomes of eligible patient recruitment rate per month, adverse events, and mean time to complete the protocol will be evaluated. Clinical and functional outcomes will be assessed before, immediately after, and 30 minutes after the intervention: pain (FLACC), respiratory distress (BSA), vital signs (HR, RR, BP, SpO2), diaphragmatic excursion and velocity (ultrasound), and amount of secretion removed. This study was approved by the UFRN/FACISA Ethics Committee (opinion: 8.283.082) and registered in the Brazilian Registry of Clinical Trials (ReBEC). Partial results: To date, 6 infants have been included in the study. The protocol demonstrated good operational feasibility in the pediatric ICU, with a high adherence rate, no refusals from legal guardians, and a total mean protocol application time of 25.7 minutes, consistent with the unit's care routine. During the assessments, vital signs remained stable and pain and respiratory discomfort scores remained low, in addition to a trend of increased peripheral oxygen saturation and ultrasound measurements of diaphragmatic excursion and contraction velocity after the physiotherapy interventions. No adverse events associated with the interventions were recorded, demonstrating good initial safety and feasibility of the proposed clinical trial.
