To evaluate the effectiveness of chest physical therapy (CP) in reducing the clinical score in infants with acute viral bronchiolitis (AVB).
Randomized controlled trial of 30 previously healthy infants (mean age 4.08 SD 3.0 months) with AVB and positive for respiratory syncytial virus (RSV), evaluated at three moments: at admission, then at 48 and 72 hours after admission. The procedures were conducted by blinded assessors to each of three groups: G1 - new Chest Physical therapy- nCPT (Prolonged slow expiration - PSE and Clearance rhinopharyngeal retrograde - CRR), G2 - conventional Chest Physical therapy- cCPT (modified postural drainage, expiratory compression, vibration and percussion) and G3 - aspiration of the upper airways. The outcomes of interest were the Wang's clinical score (CS) and its components: Retractions (RE), Respiratory Rate (RR), Wheezing (WH) and General Conditions (GC).
The CS on admission was reduced in G1 (7.0-4.0) and G2 (7.5-5.5) but was unchanged in G3 (7.5-7.0). We observed a change 48 hours after hospitalization in G1 (5.5-3.0) and G2 (4.0-2.0) and in 72 hours, there was a change in G1 (2.0-1.0).
The CP was effective in reducing the CS in infants with AVB compared with upper airway suction only. After 48 hours of admission, both techniques were effective and nCPT techniques were also effective in the 72 hours after hospitalization compared with cCPT techniques.
评估胸部物理治疗（CP）对降低急性病毒性细支气管炎（AVB）婴儿临床评分的有效性。
对30名先前健康的患有AVB且呼吸道合胞病毒（RSV）检测呈阳性的婴儿（平均年龄4.08±3.0个月）进行随机对照试验，在三个时间点进行评估：入院时、入院后48小时和72小时。评估由对三个组不知情的评估人员进行：G1组——新的胸部物理治疗-nCPT（延长缓慢呼气-PSE和鼻咽喉逆行清理-CRR），G2组——传统胸部物理治疗-cCPT（改良体位引流、呼气压迫、振动和叩击），G3组——上呼吸道抽吸。感兴趣的结果是王式临床评分（CS）及其组成部分：凹陷（RE）、呼吸频率（RR）、喘息（WH）和一般状况（GC）。
入院时，G1组（7.0-4.0）和G2组（7.5-5.5）的CS降低，但G3组（7.5-7.0）未变。我们观察到住院48小时后G1组（5.5-3.0）和G2组（4.0-2.0）有变化，72小时时G1组有变化（2.0-1.0）。
与仅进行上呼吸道抽吸相比，CP对降低AVB婴儿的CS有效。入院48小时后，两种技术均有效，与cCPT技术相比，nCPT技术在住院72小时后也有效。
