简要总结
The aim of this study is to examine the effect of SSC compared to sucrose on pain induced activity in the preterm infant brain using: a) series of low intensity experimental stimuli (PinPrick);and b) medically required heel lance. Secondary objectives include determining: a) differences between behavioral pain response and pain response during heel lance; and b) rate of adverse events across groups.
详细描述
Hospitalized preterm infants undergo an average of 12 painful procedures daily, with less than half receiving pain relief. Poorly treated early pain can have long lasting negative effects that impact later learning, development, and reaction to future pain, stress, and emotional experiences. While sweet tasting solution (sucrose) is considered the standard of care for reducing behavioral responses to acute procedural pain in preterm infants, some evidence that sucrose may not similarly reduce pain related brain activity raises concerns regarding the degree of pain relieving effect. This concern is especially relevant as the use of sucrose to manage repeated acute pain has not been found to prevent heightened later pain associated with this exposure. Strong evidence suggests that maternal infant skin-to-skin contact (SSC) is effective in reducing behavioral responses to pain. Given the multi-sensory benefits of SSC, it is highly likely that SSC provided during pain in early life may reduce pain induced brain activity.
Infants ( n=126) (32 to 36 completed weeks gestational age) admitted to the Neonatal Intensive Care Unit, and their mothers within the first seven days of age will be randomly assigned to receive: i) SSC or ii) 24 % oral sucrose. Each baby will receive both the PinPrick and heel lance, following a no treatment baseline period. The primary outcome is pain related brain activity measured using an electroencephalogram (EEG) pain-specific event-related potential. Secondary outcomes include pain intensity measured using a behavioural infant pain assessment tool (Premature Infant Pain Profile-Revised) and rate of adverse events.
This will be the first study to examine the effect of SSC on pain induced brain activity in the preterm infant brain during experimental and clinical pain stimuli, measured using EEG. Given the negative neurodevelopmental outcomes associated with unmanaged pain, it is imperative that preterm infants receive the most effective pain relieving treatments to improve their health outcomes.

盲法说明
Two research assistants (RA1, RA2) who are blinded to the intervention condition will be hired to complete facial coding and calculation of infant PIPP-R scores. Each research assistant will only code data for preterm infants in the skin to skin condition (RA1) or the sucrose condition (RA2) and will not be aware of whether they are watching preterm infant responses to noxious or non-noxious stimulation. To minimize observer bias, research assistants will not be informed of the study design, will not be permitted to attend data collection sessions, and will not share datasets or communicate with the other research assistant regarding the study. During data collection, up close video recording of only the preterm infants face will be completed to attempt to keep coders blind to the nature of the intervention.

研究组 & 干预措施
Skin-to-skin contact
Infants will be placed in full ventral skin-to-skin with their mother at least fifteen minutes prior to heel lance to allow time to settle and recover following transfer. Positioning will be determined based on individual maternal preference in order to optimize comfort as well as facilitate ease of access to the infant's foot for blood collection, while also attempting to minimize disruption of continuous EEG, heart rate, oxygen saturation, and video recording. Skin to skin contact will continue until the procedure is completed.
In addition, infants will be offered non-nutritive sucking using a gloved finger or pacifier (based on parental preference) during SSC. Whether infants are actively sucking during the procedure will be recorded by the research coordinator.
干预措施: Skin-to-skin contact (Behavioral)
24% Oral sucrose
Infants will be placed in a cot or in an incubator, depending on their gestational age, for the duration of the blood collection. Administration of 0.12mls (0.04mls per drop) of 24 percent oral sucrose will occur two minutes prior to the heel lance.
The infants will be offered non-nutritive sucking using a gloved finger or pacifier (based on parental preference) immediately following administration of the complete 24 percent oral sucrose dose. Whether infants are actively sucking during the procedure will be recorded by the research coordinator.
干预措施: 24% oral sucrose (Drug)
结局指标
主要结局
Pain-specific event related potential
时间窗: Isolated within the one-minute window post-procedure at lead CZ
The primary outcome measure will be pain-specific brain activity measured using a dense array neonatal electroencephalogram (EEG) recording that is time-locked to a medically required heel lance. Infant EEG activity will be recorded from a HydroCel Geodesic Sensor Net positioned according to the modified international 10/20 electrode placement system on a 128 Channel Geodesic EEG SystemTM 400 MR series (Electrical Geodesics Incorporated, Eugene, Oregon, USA). Pain-specific event related potentials will specifically be examined and isolated at electrode sites Cz, as previous research has reported pain-specific activity at this site in both infants and adults.
次要结局
- Premature Infant Pain Profile-Revised(Composite pain scores with be averaged over 30 second epochs and reported at 30, 60, 90, 120 seconds post heel lance)
- Recovery(The point at which the preterm infant's heart rate reaches baseline levels and is sustained for no less than five to seven beats following the heel lance, time will vary across patients but will be anticipated to be no longer than 5 minutes)
- Maternal acceptability: questionnaire(Immediately post-procedure)
