Infant Distress

Reducing toxic stress in the neonatal intensive care unit to improve infant outcomes

In 2011, the American Academy of Pediatrics (AAP) published a technical report on the lifelong effects of early toxic stress on human development, and included a new framework for promoting pediatric health: the Ecobiodevelopmental Framework for Early Childhood Policies and Programs. We believe that hospitalization is a specific form of toxic stress for the neonatal patient, and that toxic stress must be addressed by the nursing profession in order to substantially improve outcomes for the critically ill neonate. Approximately 4% of normal birthweight newborns and 85% of low birthweight newborns are hospitalized each year in the highly technological neonatal intensive care unit (NICU). Neonates are exposed to roughly 70 stressful procedures a day during hospitalization, which can permanently and negatively alter the infant's developing brain. Neurologic deficits can be partly attributed to the frequent, toxic, and cumulative exposure to stressors during NICU hospitalization. However, the AAP report does not provide specific action steps necessary to address toxic stress in the NICU and realize the new vision for pediatric health care outlined therein. Therefore, this paper applies the concepts and vision laid out in the AAP report to the care of the hospitalized neonate and provides action steps for true transformative change in neonatal intensive care. We review how the environment of the NICU is a significant source of toxic stress for hospitalized infants. We provide recommendations for caregiving practices that could significantly buffer the toxic stress experienced by hospitalized infants. We also identify areas of research inquiry that are needed to address gaps in nursing knowledge and to propel nursing science forward. Finally, we advocate for several public policies that are not fully addressed in the AAP technical report, but are vital to the health and development of all newborns.

A Systematic Review of Behavioral and Environmental Interventions for Procedural Pain Management in Preterm Infants

PROBLEM

Current research suggests behavioral and environmental interventions to prevent neonatal pain prior to an invasive procedure are rarely administered and seldom documented. The aim of this study was to systematically review findings from published randomized controlled trials that tested the effects of behavioral and environmental procedural pain management interventions on behavioral pain response in preterm infants.

ELIGIBILITY CRITERIA

Randomized controlled trials examining the effects of behavioral and environmental pain management interventions on behavioral pain response in preterm infants were identified. Articles accepted for inclusion met the following criteria: English language, original, peer refereed, randomized controlled clinical trials published within the past 5 years, study sample: preterm infants, setting: neonatal intensive care units, study intervention behavioral and environmental, outcome pain measurement score from valid and reliable pain scale.

SAMPLE

Fourteen randomized controlled trials from a literature search of PubMed and Medline databases were included in this review.

RESULTS

Across all age groups, facilitated tucking, oral sucrose, and kangaroo care decreased behavioral and physiologic pain response alone and in combination with other behavioral and environmental interventions.

CONCLUSION

Among preterm infants, facilitated tucking, oral sucrose, and kangaroo care significantly mitigates biobehavioral pain response associated with acutely painful procedures.

IMPLICATIONS

Evidence suggests that behavioral and environmental interventions can decrease biobehavioral pain response associated with acutely painful procedures in preterm infants. This review highlights the need for rigorous studies to help healthcare providers to build a tailored pain treatment plan for preterm infants.

Uncertainty of Parents With Children Undergoing Herniorrhaphy

This study reports the association between parental uncertainty and characteristics of 123 parent-child dyads prior to the child's herniorrhaphy. A cross-sectional study design and Mishel's Parents' Perception of Uncertainty Scale (PPUS) were used. Parent participants were married (98%), had a university degree (45%), identified with a religion (77%), and worked (69%). More boys (76%) than girls (23%) underwent herniorrhaphy (average age = 2.26 years); 60% were the first-born child and 25% were premature. More children presented with unilateral (63.4%; right = 44.7%, left = 18.7%) than bilateral (36.6%) hernias and most were primary (98%). Overall uncertainty was perceived as moderate and ambiguity had the highest score. Religion, birth order (first child), and hernia site (bilateral) explained 20.6% of total variance of uncertainty. Providing information about postoperative symptom and pain management is important for all parents, particularly for parents identified with a religion and whose first-born child had bilateral hernias.

Perception of pain and distress in intubated and mechanically ventilated newborn infants by parents and health professionals

Background

An understanding of perceptions of parents and health caregivers who assist critically ill neonates is necessary to comprehend their actions and demands. Therefore this study aim to analyze the agreement among parents, nurse technicians and pediatricians regarding the presence and intensity of pain and distress in mechanically ventilated and intubated newborn infants.

Methods

Cross-sectional study comprising 52 infants and 52 trios of adults composed of one parent, one nurse technician, and one pediatrician who all observed the same infant. All infants were intubated and under mechanical ventilation and were not handled during the observations. Each newborn was simultaneously observed by the trio of adults for 1 minute to evaluate the presence of pain and distress. The intensity of pain and distress that the adults believed was felt by the infants was marked in a visual analogical scale. Adults’ agreement about the simultaneous presence of pain and distress in each infant was analyzed by marginal homogeneity and Cochran tests. The agreement about the intensity of pain and distress in each infant was studied by Bland-Altman plot and intraclass correlation coefficient (ICC).

Results

The assessments of pain and distress were heterogeneous in all three investigated groups of adults as determined by the results of a Bland-Altman plot. The presence of distress was more frequently reported compared with pain (marginal heterogeneity, p < 0.01). The pain and distress scores in each adult group were not correlated as shown by ICC [parents, 0.36 (95% CI: 0.01-0.63); nurses 0.47 (0.23-0.66); pediatricians, 0.46 (0.22-0.65)].

Conclusions

Adults systematically underscore pain in comparison to distress in mechanically ventilated newborns, without recognizing the association between them.
