| Abstract: | Contact-heel percussion and cupping (with a Laerdal Face Mask) are two common modified percussion techniques performed by local physiotherapists in their management of preterm neonates with respiratory problems. This study was a clinical randomized, repeated treatment design which aimed to compare the effects of these 2 different percussion techniques by the weight of sputum aspirated after each treatment, as well as the heart rate (HR) and oxygen saturation (SpO2), measured by pulse oximetry, in neonates. Fourteen neonates (8 males, 6 females) with mean birth weight of 1582 grams, and mean gestation of 30.56 weeks, presented with sputum retention, were recruited from the Neonatal Intensive Care Unit (NICU) of the Queen Elizabeth Hospital (QEH) as subjects. Informed consent was obtained from either of the parents. Each subject was exposed to all 3 study protocols in a random order on the same day. In each protocol, the subject was positioned in a tilted head-up position. Two minutes of contact-heel percussion, cupping or no percussion (control) was performed twice, and each was followed by suctioning. The weight of sputum aspirated in a suction catheter was measured by a beam balance scale, whereas HR and SpO2 were measured by a pulse oximeter. Data were recorded every 30 seconds from 5 minutes before treatment to 15 minutes after treatment. Non-parametric tests were employed for analysis of the data from the small sample size. Results showed that the weight of sputum aspirated in both percussion groups were greater than that of the control group (p< 0.05, Kruskal-Wallis 1-way analysis of variance by ranks). Chest physiotherapy programme (CPT) with contact-heel percussion resulted in an increase in HR (p < 0.05, Wilcoxon signed-ranks test). No significant difference in SpO2 was found in both percussion groups. During and after treatment, HR and SpO2 measured in both percussion groups laid within safety limits. It was concluded that a CPT which included both contact-heel percussion and cupping techniques, together with suctioning, could enhance the clearance of pulmonary secretions: A further large scale study was suggested so as to support evidenced-based clinical practice. |
