Avaliação das características clínicas de lactentes submetidos a terapia oscilatória de alta frequência na parede torácica: estudo piloto

Abstract

Introduction: High Frequency Oscillatory Chest Wall Therapy (HFCWO) is one of the therapies used to mobilize secretions in people with respiratory diseases. The Expector® kangaroo version was developed in Brazil to offer this therapy to infants. Objective: To analyze the clinical signs of infants submitted to the use of HFCWO through the Expector® kangaroo device. Methodology: This is a case series, prospective and quantitative. Approved by the UFRN/FACISA Research Ethics Committee (Opinion No. 5,636,504) and registered with REBEC (No. RBR-5r8v8qz). The sample consisted of healthy infants, aged 3 to 6 months, divided into 3 groups (2 experimental and 1 control). The control group (CG) used the deactivated equipment. The experimental groups used Expector® in different configurations (G2 and G3). The participants were evaluated before, during and after its use. The outcomes assessed were alertness, pain (Children and Infant's Postoperative Pain Scale - CHIPPS), respiratory (RR) and heart rate (HR) and peripheral oxygen saturation (SpO2). Data were analyzed by descriptive statistics using the Microsoft Excel® program. Results:The study included 10 infants with a mean age of 4±0.73 months, 6 (60%) female, with a mean weight of 5850±895.4 grams and mean trunk size of 34.5±3.6 cm. Two (20%) infants were allocated to the control group, 4 (40%) to G2, 4 (40%) to G3. There was an increase in HR in only one infant at the end of the intervention, an increase in RR in three infants between the beginning and the end of the intervention, and an increase in pain mainly during the reassessment. Only three infants were asleep during the intervention. One of the infants had regurgitation. Conclusion: The kangaroo version of Expector® promotes an intervention without significant clinical changes. However, greater observation is recommended regarding signs of pain and the adjustment of the oximeter used.
