Item Open Access A longitudinal analysis of the development of infant facial expressions in responses to acute pain: Immediate and regulatory expressions(Pain, 2012) Ahola Kohut, Sara; Pillai Riddell, Rebecca; Flora, David; Oster, HarrietFacial expressions during infancy are important to examine as infants do not have the language skills to describe their experiences. This is particularly vital in the context of pain where infants depend solely on their caregivers for relief. The objective of the current study was to investigate the development of negative infant facial expressions in response to immunization pain over the first year of life. Infant facial expressions were examined longitudinally using a subsample of 100 infants that were each videotaped during their 2-, 4-, 6-, and 12-month routine immunization appointments. Infant facial expressions were coded using BabyFACS for the first minute after a painful needle prick. Facial expressions were examined with a catalogue of the most commonly occurring facial expressions. Results demonstrated that clear differences were seen over ages. Infants display a variety of facial expressions with some of the components of adult pain expressions immediately after the needle and abate shortly after. However, infants did not display adult expressions of discrete negative emotions. Instead, infants display a variety of generalized pain and distress faces aimed at gaining caregiver aid. The development of non-verbal communication in infants, particular facial expressions, remains an important area of inquiry. Further study into accurately measuring infant negative emotions, pain, and distress is warranted.Item Open Access Chronic Pain in Hospitalized Infants: Health Professionals' Perspectives(2009) Pillai Riddell, Rebecca; Stevens, Bonnie; McKeever, Patricia; Katz, Joel; Asztalos, Liz; Din, Laila; Ahola Kohut, Sara; Gibbins, SharynPotentially significant numbers of infants hospitalized in Neonatal Intensive Care Units (NICUs) and Pediatric Intensive Care Units (PICUs) experience chronic pain. However, the phenomenon of chronic pain in infancy has neither been defined nor described adequately by researchers. To stimulate and focus further work in the area, the purpose of this study was to explore expert opinions on definitional and assessment parameters of infant chronic pain. Forty-five health care professionals, with a median of 17 years of clinical experience, were recruited from 4 tertiary-level, university-affiliated institutions. Individual (n=24) and group (n=21) interviews were conducted by trained interviewers. Qualitative data were analyzed using a standard descriptive method. Health care professionals were able to offer preliminary definitions of chronic pain in infants. The most contentious definitional issue was whether iatrogenically prolonged pain (pain induced and maintained by medical procedures) should be considered chronic pain. Possible indicators for chronic pain included inability to settle, social withdrawal, constant grimacing, tense body, hypo- or hyper-reactions to acute pain, and dysregulated sleep or feeding patterns. These indicators differed significantly from those traditionally used to measure acute pain.Item Open Access Non-pharmacological management of infant and young child procedural pain: An abridged Cochrane review(Pain and Research Management, 2011) Pillai Riddell, Rebecca; Racine, Nicole; Turcotte, Kara; Uman, Lindsay; Horton, Rachel; Ahola Kohut, Sara; Din Osmun, Laila; Hillgrove-Stuart, Jessica; Stevens, Bonnie; Lisi, DianaBACKGROUND: Acute pain and distress during medical procedures are commonplace for young children. OBJECTIVE: To assess the efficacy of nonpharmacological interventions for acute procedural pain in children up to three years of age. METHODS: Study inclusion criteria were: participants <3 years of age, involved in a randomized controlled or crossover trial, and use of a ‘no-treatment’ control group (51 studies; n=3396). Additional studies meeting all criteria except for study design (eg, use of active control group) were qualitatively described (n=20). RESULTS: For every intervention, data were analyzed separately according to age group (preterm-born, term-born neonate and older infant/young child) and type of pain response (pain reactivity, immediate pain-related regulation). The largest standardized mean differences (SMD) for pain reactivity were as follows: sucking-related interventions (preterm: −0.42 [95% CI −0.68 to −0.15]; neonate −1.45 [CI −2.34 to −0.57]), kangaroo care (preterm −1.12 [95% CI −2.04 to −0.21]), and swaddling/facilitated tucking (preterm −0.97 [95% CI −1.63 to −0.31]). For immediate pain-related regulation, the largest SMDs were: sucking-related interventions (preterm −0.38 [95% CI −0.59 to −0.17]; neonate −0.90 [CI −1.54 to −0.25]), kangaroo care 0.77 (95% CI −1.50 to −0.03]), swaddling/facilitated tucking (preterm −0.75 [95% CI −1.14 to −0.36]), and rocking/holding (neonate −0.75 [95% CI −1.20 to −0.30]). The presence of significant heterogeneity limited confidence in nonsignificant findings for certain other analyses. CONCLUSIONS: Although a number of nonpharmacological treatments have sufficient evidence supporting their efficacy with preterm infants and healthy neonates, no treatments had sufficient evidence to support efficacy with healthy older infants/young children.
