State systems development in high-risk newborns in the neonatal intensive care unit: identification and management of sleep, alertness, and crying

The effect of cognitive-behavioral counseling with or without Citrus aurantium essential oil on sleep quality in pregnant women: a randomized controlled trial

Sleep disorder is very common during pregnancy. Non-pharmacological treatments are a priority to improve the sleep pattern. This study aimed to determine the effect of cognitive-behavioral counseling with or without Citrus aurantium essential oil on sleep quality (primary outcome) and anxiety and quality of life (secondary outcomes). This randomized controlled trial was performed on 75 pregnant women in Tabriz, Iran. Participants were randomly assigned to the intervention and control groups. The first intervention group received 8 sessions of cognitive-behavioral counseling and aromatherapy with Citrus aurantium essential oil 15-20 min before bedtime. The second intervention group received cognitive-behavioral counseling and aromatherapy with placebo and the control group received only routine prenatal care. Pittsburgh Sleep Quality Index, Pregnancy-Specific Quality of life Questionnaire, and Pregnancy-Specific Anxiety Scale were completed before and after intervention. After the intervention based on ANCOVA test and by adjusting the baseline score, the mean score of anxiety in the intervention group 1 (AMD: - 4.54; 95% CI - 6.79 to - 2.28) and intervention group 2 (AMD: - 3.30; 95% CI - 5.60 to - 0.97) was significantly lower than the control group. Also, the mean score of quality of life in intervention group 1 (AMD: 2.55; 95% CI 0.45-4.65) and intervention group 2 (AMD: 2.72; 95% CI 0.60-4.83) was significantly higher than the control group, but there was no statistically significant difference between the study groups in terms of sleep quality (P > 0.05). Also, there was no statistically significant difference between the two intervention groups after the intervention in terms of anxiety (P = 0.379) and quality of life (P = 0.996). Cognitive-behavioral counseling reduced anxiety and improved quality of life. However, further trials are required to reach a definitive conclusion.

Survey of Neonatal Intensive Care Unit Nurses' Use of a Motion/Sound Infant Seat

BACKGROUND

Perinatal substance exposure is an increasing concern in infants being cared for in neonatal intensive care units. Current recommendations support nonpharmacologic treatments for this population of infants. Multimodal (motion, sound) seats are often employed to soothe infants.

PURPOSE

The purpose of this study was to survey neonatal intensive care unit nurses on their practices regarding the use of a motion/sound infant seat.

METHODS

Sixty-six nurses (52% of 126 total nurses) completed the survey about their self-disclosed practices that included (1) reasons for use; (2) rationale for choice of settings of motion and sound; (3) duration of time infants spent in seat in one session; (4) perception of positive infant response; (5) who places infants in the seat; and (6) nursing instructions dispensed prior to use.

RESULTS

Chief reasons for use were infant state, lack of persons to hold infants, and a diagnosis of neonatal abstinence syndrome. Rationale for choice of motion and sound settings included trial and error, prior settings, personal preferences/patterns, assumptions, and random selection. Nurse responses regarding the amount of time the infant was placed in the seat in a single session ranged from 10 to 360 minutes, with determining factors of infant cues, sleeping, feeding, and someone else to hold the infant.

IMPLICATIONS FOR PRACTICE

As nonpharmacologic treatments evolve, nurses need guidelines for safe, effective interventions to care for infants.

IMPLICATIONS FOR RESEARCH

Further research is necessary to ascertain the responses of withdrawing infants and to establish guidelines and education for use of the motion/sound infant seat.

Nurturing the preterm infant brain: leveraging neuroplasticity to improve neurobehavioral outcomes

An intrinsic feature of the developing brain is high susceptibility to environmental influence-known as plasticity. Research indicates cascading disruption to neurological development following preterm (PT) birth; yet, the interactive effects of PT birth and plasticity remain unclear. It is possible that, with regard to neuropsychological outcomes in the PT population, plasticity is a double-edged sword. On one side, high plasticity of rapidly developing neural tissue makes the PT brain more vulnerable to injury resulting from events, including inflammation, hypoxia, and ischemia. On the other side, plasticity may be a mechanism through which positive experience can normalize neurological development for PT children. Much of the available literature on PT neurological development is clinically weighted and focused on diagnostic utility for predicting long-term outcomes. Although diagnostic utility is valuable, research establishing neuroprotective factors is equally beneficial. This review will: (1) detail specific mechanisms through which plasticity is adaptive or maladaptive depending on the experience; (2) integrate research from neuroimaging, intervention, and clinical science fields in a summary of findings suggesting inherent plasticity of the PT brain as a mechanism to improve child outcomes; and (3) summarize how responsive caregiving experiences situate parents as agents of change in normalizing PT infant brain development.

Structured Educational Intervention Leads to Better Infant Positioning in the NICU

PURPOSE

The purpose is to test the effectiveness of an educational intervention in improving infant positioning because positioning may interfere with neuromotor development.

METHODS

A quality improvement (QI) project was initiated to increase knowledge and improve the compliance of nurses and physicians in infant positioning using the Infant Positioning Assessment Tool (IPAT). The project was part of Neonatal Individualized Developmental Care Assessment Program (NIDCAP) training. It included informal discussion and practice about infant positions.

MAIN OUTCOME VARIABLES

Staff knowledge, IPAT score.

RESULTS

Fifty-two pediatric residents and 39 NICU nurses participated in this project. The mean knowledge assessment test score improved significantly for both nurses (p < .0001) and residents (p < .0001) postintervention; IPAT scores increased significantly from 3.4 (±2. 5) to 8.1 (±2.7) (p < .001).

CONCLUSION

Nurses' education with hands-on practice improved infant positioning in the NICU; this may lead to fewer positional deformities and possibly an improved developmental outcome.

Infant born preterm have delayed development of adaptive postural control in the first 5 months of life

Infants born preterm are at increased risk of developmental disabilities, that may be attributed to their early experiences and ability to learn. The purpose of this paper was to evaluate the ability of infants born preterm to adapt their postural control to changing task demands.

METHODS

This study included 18 infants born at 32 weeks of gestation or less whose posture was compared in supine under 2 conditions, with and without a visual stimulus presented. The postural variability, measured with root mean squared displacement of the center of pressure, and postural complexity, measured with the approximate entropy of the center of pressure displacement were measured longitudinally from 2.5 to 5 months of age.

RESULTS AND DISCUSSION

The infants looked at the toys in midline for several months prior to adapting their postural variability in a manner similar to full term infants. Only after postural variability was reduced in both the caudal cephalic and medial lateral direction in the toy condition did the infants learn to reach for the toy. Postural complexity did not vary between conditions. These findings suggest that infants used a variety of strategies to control their posture. In contrast to research with infants born full term, the infants born preterm in this study did not identify the successful strategy of reducing movement of the center of pressure until months after showing interest in the toy. This delayed adaptation may impact the infants ability to learn over time.

Behavioral observation differentiates the effects of an intervention to promote sleep in premature infants: a pilot study

PURPOSE

Sleep and ongoing cycling of sleep states are required for neurosensory processing, learning, and brain plasticity. Many aspects of neonatal intensive care environments such as handling for routine and invasive procedures, bright lighting, and noise can create stress, disrupt behavior, and interfere with sleep in prematurely born infants. The study empirically investigated whether a 30-minute observation of infant sleep states and behavior could differentiate an intervention to promote sleep in premature infants with feeding difficulties relative to conventional care (standard positioning, standard crib mattress [SP]). We included an intervention to determine the ability of the method to discriminate treatments and generate a benchmark for future improvements. The intervention, a conformational positioner (CP), is contoured around the infant to provide customized containment and boundaries. To more fully verify the 30-minute observational sleep results, standard polysomnography was conducted simultaneously and sleep outcomes for the 2 modalities were compared.

SUBJECTS

In a randomized crossover clinical trial, 25 infants, 31.5 ± 0.6 weeks' gestational age and 38.4 ± 0.6 weeks at the study, with gastrointestinal conditions or general feeding difficulties used each intervention during an overnight neonatal intensive care unit sleep study.

METHODS

Infant sleep states and behaviors were observed during two 30-minute periods--that is, on the positioner and mattress--using the naturalistic observation of newborn behavior. Two certified developmental care nurses assessed sleep state, self-regulatory, and stress behaviors during 2-minute intervals and summed over 30 minutes. Sleep characteristics from standard polysomnography were measured at the time of behavior observations.

RESULTS

Infants on CP spent significantly less time in alert, active awake, or crying states by observation compared with SP. Surgical subjects spent more time awake, active awake, or crying and displayed a higher number of behavior state changes than the nonsurgical infants. The percentage of time in observed deep sleep and quiet sleep was correlated with both percentage sleep efficiency (r = 0.78) and fewer state shifts per hour (r = -0.65) from electroencephalogram (EEG). Sleep efficiency by EEG was greater on CP versus SP.

CONCLUSIONS

The CP enabled sleep compared with the standard mattress (SP) over 30-minute observation periods. Sleep status from behavioral observation was verified by standard EEG-based sleep techniques. Behavioral observation of sleep states may be a useful strategy for measuring the effectiveness of strategies to facilitate sleep in premature infants. Surgical subjects may benefit from additional interventions to promote sleep.

Neonatal neurobehavior effects following buprenorphine versus methadone exposure

AIM

To determine the effects of in utero exposure to methadone or buprenorphine on infant neurobehavior.

DESIGN

Three sites from the Maternal Opioid Treatment: Human Experimental Research (MOTHER) study, a double-blind, double-dummy, randomized clinical trial participated in this substudy.

SETTING

Medical Centers that provided comprehensive maternal care to opioid-dependent pregnant women in Baltimore, MD, Providence, RI and Vienna, Austria.

PARTICIPANTS

Thirty-nine full-term infants.

MEASUREMENTS

The Neonatal Intensive Care Unit (NICU) Network Neurobehavioral Scale (NNNS) was administered to a subgroup of infants on postpartum days 3, 5, 7, 10, 14-15 and 28-30.

FINDINGS

While neurobehavior improved for both medication conditions over time, infants exposed in utero to buprenorphine exhibited fewer stress-abstinence signs (P < 0.001), were less excitable (P < 0.001) and less over-aroused (P < 0.01), exhibited less hypertonia (P < 0.007), had better self-regulation (P < 0.04) and required less handling (P < 0.001) to maintain a quiet alert state relative to in utero methadone-exposed infants. Infants who were older when they began morphine treatment for withdrawal had higher self-regulation scores (P < 0.01), and demonstrated the least amount of excitability (P < 0.02) and hypertonia (P < 0.02) on average. Quality of movement was correlated negatively with peak NAS score (P < 0.01), number of days treated with morphine for NAS (P < 0.01) and total amount of morphine received (P < 0.03). Excitability scores were related positively to total morphine dose (P < 0.03).

CONCLUSION

While neurobehavior improves during the first month of postnatal life for in utero agonist medication-exposed neonates, buprenorphine exposure results in superior neurobehavioral scores and less severe withdrawal than does methadone exposure.

The Opioid dependent mother and newborn dyad: non-pharmacologic care

Opioid dependent pregnant and post-partum women and their infants are a complex and vulnerable population requiring individualized, comprehensive and multidisciplinary treatment. Though methadone maintenance in the setting of comprehensive service provision during pregnancy significantly improves pregnancy outcomes for opioid dependent women, its use has implications for the infant, most notably the Neonatal Abstinence Syndrome (NAS). NAS is comprised of physiologic signs and behaviors that indicate a dysfunctional regulation of the central and autonomic nervous systems, and is variable in its expression in affected infants. The disorganized rather than adaptive behaviors displayed by each infant undergoing the effects of in-utero opioid exposure may impair basic functions such as feeding, sleeping, and the ability to be alert and communicate clear cues to caregivers. Understanding and responding to neurobehavioral dysfunction of the newborn may help to promote the infant's self-organization and self-regulating abilities. However, the substance abusing mother's physical and psychological wellbeing may be debilitated in the perinatal period, and her ability to recognize and respond to the newborn's cues may be limited. A multi-tiered comprehensive assessment and intervention of the methadone-maintained mother, her child, and the mother/infant dyad can improve early maternal nurturing interactions, a crucial component of early infant development, particularly in this vulnerable population. The purpose of this article is to review the contribution of maternal opioid dependency to the difficulties experienced by the mother-infant dyad and their treatment providers in the postnatal period, and the non-pharmacological treatment of the infants with suggestions for practical measures with emphasis on the treatment of the mother and baby as an interactional dyad.

Individual and gender differences matter in preterm infant state development

OBJECTIVE

To further understand state development of preterm infants throughout hospitalization and the effects of selected infant characteristics on state development.

DESIGN

Secondary data analysis of a 2-group, experimental design study.

SETTING

Two nurseries in a Northwest medical center.

PARTICIPANTS

Ninety-seven hospitalized, medically stable, preterm infants. Fifty-one subjects were females.

METHODS

Two hundred and eighty-five real-time video recordings of infants performed during 4 hour interfeeding intervals. Sleep-wake states were coded at 15 second intervals.

RESULTS

Active sleep was the dominant state across postmenstrual ages. Although not statistically significant, preterm infants showed developmental changes in state organization with increased quiet sleep, drowsy, and awake, decreased active sleep, and more defined and less diffuse states over age. A significant gender effect was found, with males having less active sleep (p=.012), more drowsy (p=.03), more awake (p=.043), less defined (p=.002), and more diffuse (p=.001) states compared with females.

CONCLUSION

The predominance of active sleep during the preterm period reflects level of brain maturation. The results emphasize individual variations in state organization influenced by endogenous and environmental factors. Gender differences are potential sources of individual variation.
