| Learning Objective #1: find if swaddling to preterm infant could stabilize their physiological indicators during the suction period. |
| Learning Objective #2: find if swaddling to preterm infant could conserve their energy during the suction period. |
Background: Suctioning was a necessary procedure to ventilated preterm infants. Yet it was negative impacts on physiological indicators, which would deplete the energy of preterm infants and affect their growth and development. Purpose: to investigate the effectiveness of swaddling on indicators of heart rate, respiratory rate, O2 saturation, blood pressure and energy expenditure of preterm-infants while suctioning compared to non-swaddling. Method: This was quasi-experimental, cross-over, and repeated measurement design. Seventeen subjects whose birth weights were under 2000gm and ventilated preterm-infants were tested in a medical center. Randomized sequencing, there were 10 for swaddling first then nonswaddling, and 7 for nonswaddling first then swaddling. Used SPSS for Window 12.0 and SAS (9.1)/GEE to analyzed these data. Results: Preterm infants’ mean heart rates were more stable 9.18 beats/min while swaddling compared to non-swaddling before and after suctioning, and showed significant statistic difference (Z=-2.91, P=0.004). However, after control the times’ interaction, there were no difference between swaddling and non-swaddling in variations on heart rate. The other physiological indicators such as respiratory rate, O2 saturation and blood pressure were no group difference, and had no group and time interaction during suction stimulating to preterm-infants. Conclusion: The hypothesis of preterm infant with swaddling could stabilize their physiological indicators while suctioning period was not proved. So, it was difficult to stabilize the physiological indicators by non-pharmacological intervention during the suctioning process. But the energy was conserved because the HR > 140 beats/min in experimental groups during the suction period was less than the control groups. Implication: Although swaddling could not stabilize the physiological indicators in preterm infants during the suctioning process, their energy was conserved. The swaddling intervention was suggested to apply in the suction process for the preterms.
