Does prone or supine position influence pain responses in preterm infants at 32 weeks gestational age?
OBJECTIVE: The purpose of this study was to examine the influence of prone and supine position in preterm infants during acute pain of blood collection. SETTING: Level III Neonatal Intensive Care Unit (NICU). STUDY DESIGN: Thirty-eight preterm infants (birthweight 1339 [590-2525] g, GA 29 [25- 32] wks) were in 2 groups depending on their position in the isolette prior to and during heel lance at 32 weeks post-conceptional age. The study design was a comparison between groups (Prone, Supine) during 2 events (Baseline, Heel lance). OUTCOME MEASURE: Pain measures were multidimensional, including behavioral (sleep-wake state and facial activity) and physiological (heart rate) responses measured continuously prior to (Baseline) and during blood collection (Lance). RESULTS: Both groups of infants displayed statistically significant shifts in sleep-wake state to greater arousal, and increased facial activity and heart rate, from Baseline to Lance. Prone position was associated with significan
