OBJECTIVES: The objectives of this exploratory study were to describe the safety, comfort, and effects of applying a weighted blanket to restrict anterior chest movement on oxygenation, and regional ventilation in clinically stable, nonventilated infants, and children hospitalized with lower respiratory tract infections (LRTIs). Our hypothesis is that the application of a weighted blanket would not adversely affect comfort levels or oxygenation in nonventilated infants and children with LRTIs.
METHOD: A prospective, exploratory interventional pilot study of nonventilated children and infants aged 2 months to 9 years of age admitted to hospital for the management of a LRTI. Comfort and pain scores, vital signs (heart rate [HR], respiratory rate [RR], oxygen saturation, and blood pressure), and electrical impedance tomography (EIT) measurements were captured at baseline, immediately and at 5 min, 10 min, and 30 min after application of the blanket.
RESULTS: Thirty children (median interquartile range [IQR] 8.31 months old [2.46-22.27]; 16 [53.30%] males), received the intervention, and were included in the analysis. Just over half of the children recruited were admitted with a clinical diagnosis of pneumonia (n = 17; 56.70%). No adverse events were recorded during the study intervention. Overall, oxygen saturation increased from median (IQR) 97% (91-100) to 100% (93-100) (p < 0.001); COMFORT-B score improved from median (IQR) 13 (6-14) to 11 (6-16) (p = 0.02) from baseline to 30 min postintervention and there was no significant change in the faces, legs, activity, cry, and consolability (FLACC) pain scale.
CONCLUSION: The application of a weighted blanket in nonventilated infants and children with mild LRTI was well tolerated, with no adverse effects and was associated with improvements in comfort levels and SpO2.
