Abstract

The purposes of this study were to explore (1) the effect of but tock care (BC) on premature infant heart rate (HR) and oxygen saturation (SpO2), and (2) the effect of but tock lifting angle during BCs on HR and SpO2. The study used a repeated measure design. A convenience sample of 11 premature infants in the neonatal intensive care unit (NICU) of a medical center were studied during 30 BC events. The subjects were of a gestational age of less than and 37 weeks, and postnatal age of less than one month, with out known congenital abnormalities and with out having been treated with sedatives during the study. Infant HR and SpO2 were measured at a 30-second interval 10 min utes before and during, and 15 minutes after BC. Maximal lifting angles of BCs during the procedure were recorded. Based on the infant's individual responses to BC, 63.3% of BCs induced an increase in HR and a decrease in SpO2, defined as the change in HR and SpO2 greater than two standard deviations from the base line. In addition, 30% of BCs resulted in cardiac decelerations. The extent of the difference found in these change patterns in HR or SpO2 were all significant (p <.01) and their mean recovery times were longer than 10 minutes. More HR acceleration events occurred as the BC lifting angle exceeded ≤ 30°, and more HR deceleration events were found as the angle > 30° (p =.035).But tock care can have a significant impact on premature infant physiological stability. The BC lifting angle may play an important role in HR acceleration or deceleration. Careful observation before and after BC for premature infants is recommended.
