“…In summary, no changes in vital signs or heart rate variability could be observed in this study where an intervention comprising of the use of a swaddling device during Kangaroo care as opposed to routine Kangaroo care was analysed. In other studies, the sounds of heartbeats were reported to have a calming effect during caregiving procedures as measured by vital signs . Perhaps the stimuli employed by the swaddling device might have been of an insufficient intensity to overcome the background noise or olfactory stimuli of the NICU .…”

“…Dieter [77] and Harrison [78] suggested that systematic gentle human touch may stimulate peripheral nerves that activate the vagus nerve, thus promoting infant comfort and reducing stress, resulting in positive immediate and long term outcomes. In addition, KC compared to the incubator condition provides stimulation through the infant's prone positioning [79-83], maternal warmth [84], containment and swaddling [85-87], maternal heart sounds [88, 89], vestibular movement (mother's chest respiratory movement) [90], maternal body odor [91-93], and mother's voice [94]. Infants are apparently familiar with their mothers' odor, voice, respiratory and heart beat rhythm from the uterine environment [92] and these have soothing effects on infants.…”

Background Heel stick is the most common painful procedure for preterm infants in neonatal intensive care units. Resultant pain causes adverse physiological effects in major organ systems. Kangaroo Care (KC), involving mother-infant skin-to-skin contact is a promising analgesic for infant pain; however, the effect of KC on the autonomic nervous system's response to pain is unknown. Aim To determine if KC results in improved balance in autonomic responses to heel stick pain than the standard method where infants remain in an incubator care (IC) for the heel stick. Study Design A randomized cross-over trial. Subjects Fourteen preterm infants, 30-32 weeks gestational age and less than 9 days postnatal age. Outcome Measures Infant behavioral state, heart rate, heart rate variability (HRV) indices including low frequency (LF) and high frequency (HF) power, and the LF/HF ratio measured over Baseline, Heel Warming, Heel Stick, and Recovery periods in KC and IC conditions. Results HRV differences between KC and IC were that LF was higher in KC at Baseline (p<.01) and at Heel Stick (p< .001), and HF was higher in KC at Baseline than in the IC condition (p< .05). The LF/HF ratio had less fluctuation across the periods in KC than in IC condition and was significantly lower during Recovery in KC than in IC (p< .001). Conclusions Infants experienced better balance in response in KC than IC condition as shown by more autonomic stability during heel stick. KC may be helpful in mediating physiologic response to painful procedures in preterm infants.

“…Infants show increased magnitude of behavioral and physiologic responses to increasingly invasive procedures, and even very prematurely born infants respond to pain and differentiate stimulus intensity. 44 The duration, origin, and location of the painful stimulus and the context within which the painful stimulation occurs, such as the environment 78 and sound, 79 can also influence infant pain responses. Most research with preterm infants has focused on the responses to acute pain caused by a single noxious stimulus, but pain commonly occurs over a prolonged period or is recurrent and, as such, makes pain assessment more difficult to differentiate.…”

Pain assessment and measurement are the cornerstones of pain management. Pain assessment connotes a comprehensive multidimensional description. Conversely, pain measurement provides a numeric quantitative description of each factor illustrating pain qualities. Pain scales provide a composite score used to guide practice and research. The type of infant pain instrument chosen is a significant factor in guiding pain management practice. The purpose of this review was to summarize current infant pain measures by introducing a conceptual framework for pain measurement. Although more than 40 infant pain instruments exist, many were devised solely for research purposes; several of the newly developed instruments largely overlap with existing instruments. Integration of pain management into daily practice remains problematic. Understanding how each instrument measures infant pain allows clinicians to make better decisions about what instrument to use with which infant and in what circumstances. In addition, novel new measurement techniques need further testing.
