Study & Design

Study Type: interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Pain level in the Neonatal Infant Pain Scale (NIPS) Behavioral checklist. Timepoint: The researcher will filming neonatal behavioral changes with a video camera each time for 1 minute in 3 steps, including 5 minutes before and after intervention, during which time (during blood sampling time) and 5 minutes after the completion of blood sampling. Method of measurement: Neonatal Infant Pain Scale (NIPS) Behavioral checklist.

Secondary Outcome Measures

Name	Time	Method
Mean score of physiological indices including heart rate and hemoglobin saturation from oxygen. Timepoint: Each time for 1 minute in 3 steps including 5 minutes before and after the intervention, during it (during the bleeding time) and 5 minutes after the completion of blood sampling. Method of measurement: For measuring physiological parameters of pain including heart rate and hemoglobin saturation of oxygen, a calibrate pulse oximetry device, the model NOVAMETRIX will be used.
