A new type of swaddling clothing improved development of preterm infants in neonatal intensive care units

Effects of the use of a cocoon on the autonomic, motor, and regulatory systems in preterm newborns: Randomized clinical trial

INTRODUCTION

The wrapping of the newborn in an orthopedic tubular mesh, simulating a cocoon, can allow the infant to regain the feeling of security and stability experienced in the uterus given that the movement of one of the parts of the body exerts tactile and pressure variation in others.

OBJECTIVE

We aimed to evaluate the influence of an orthopedic tubular mesh, simulating a cocoon, in therapeutic positioning, on the variables of the autonomous, motor, and regulatory systems of preterm newborns.

METHODS

A controlled and randomized clinical trial was conducted with preterm newborns positioned in dorsal decubitus and divided into two groups: (a) cocoon - newborns covered with an orthopedic tubular mesh, and (b) control - newborns positioned according to the sector's routine and without the use of an orthopedic mesh. During the follow-up, each newborn was placed in the position for 30 min and was recorded for a total of 2 min, once at the beginning and again at the end of the observation period. Variables related to the autonomous system (heart rate, respiratory rate, and peripheral oxygen saturation), motor system (general movements), and regulatory system (Neonatal Infant Pain Scale) were evaluated before and after the intervention. The videos were evaluated by a researcher blind to the purpose of the study, and the resulting data were analyzed using SPSS.

RESULTS

Of the 40 preterm newborns evaluated (32.5 ± 1.83 weeks), 21 were female, and 20 were allocated to the cocoon group. The variables related to the autonomous, motor, and regulatory systems remained unchanged following the positioning in the cocoon, as compared to the typical positioning employed in the neonatal unit.

CONCLUSION

The simulation of a cocoon, utilizing an orthopedic tubular mesh, when applied to preterm newborns admitted to a neonatal intensive care unit can contribute to maintaining low levels of stress, without altering variables of the autonomous, motor, and regulatory systems.

Early full-day leg movement kinematics and swaddling patterns in infants in rural Guatemala: A pilot study

BACKGROUND

Tools to accurately assess infants' neurodevelopmental status very early in their lives are limited. Wearable sensors may provide a novel approach for very early assessment of infant neurodevelopmental status. This may be especially relevant in rural and low-resource global settings.

METHODS

We conducted a longitudinal observational study and used wearable sensors to repeatedly measure the kinematic leg movement characteristics of 41 infants in rural Guatemala three times across full days between birth and 6 months of age. In addition, we collected sociodemographic data, growth data, and caregiver estimates of swaddling behaviors. We used visual analysis and multivariable linear mixed models to evaluate the associations between two leg movement kinematic variables (awake movement rate, peak acceleration per movement) and infant age, swaddling behaviors, growth, and other covariates.

RESULTS

Multivariable mixed models of sensor data showed age-dependent increases in leg movement rates (2.16 [95% CI 0.80,3.52] movements/awake hour/day of life) and movement acceleration (5.04e-3 m/s2 [95% CI 3.79e-3, 6.27e-3]/day of life). Swaddling time as well as growth status, poverty status and multiple other clinical and sociodemographic variables had no impact on either movement variable.

CONCLUSIONS

Collecting wearable sensor data on young infants in a rural low-resource setting is feasible and can be used to monitor age-dependent changes in movement kinematics. Future work will evaluate associations between these kinematic variables from sensors and formal developmental measures, such as the Bayley Scales of Infant and Toddler Development.

Multisensory stimulation bundles on sleep and neurobehavioral development in the first year after birth in very preterm infants: a randomized crossover controlled study protocol

BACKGROUND

Disrupted sleep is believed to contribute to short- and long-term neurodevelopmental problems in very preterm infants (VPIs). This study presents a protocol for an evaluator-blinded, randomized crossover trial. It aims to assess the sleep efficiency of hospitalized VPIs by providing multisensory stimulation bundles. Furthermore, it aims to observe the intervention impacts on sleep during hospitalization of the VPIs and their sleep and neurodevelopmental outcomes during the first year of post-discharge follow-up.

METHODS

The study will be conducted in the neonatology department of a tertiary pediatric teaching hospital. All the eligible VPIs will undergo two types of care in random order: "standard care" (2 weeks) and "standard care plus multisensory stimulation bundles," each lasting 2 weeks. A generated list of random numbers will be used for case sequence allocation. Sleep outcomes will be evaluated using the Actiwatch-2 Actigraph. Moreover, the amplitude-integrated electroencephalography and the Griffiths Mental Development Scales will be used to measure the neurodevelopmental outcomes during hospitalization and in the first year of follow-up of the VPIs.

DISCUSSION

The intervention protocol of this study differs from that of other traditional interventions by producing precise and consistent supportive stimulations, similar to maternal tactile, auditory, posture, and visual effects for hospitalized VPIs. This protocol could be an effective measure to facilitate sleep and early neurodevelopment of VPIs. The expected outcomes will help confirm the implementation and generalization of the multisensory stimulation bundles' care protocol in neonatology departments. We expect that the study will positively impact hospitalized VPIs, especially in their sleep and early neurodevelopmental outcomes. It will also provide a new perspective regarding parent and infant interaction strategies, particularly for newborn intensive care units that limit visits because of the global spread of COVID-19.

A systematic review of improved positions and supporting devices for premature infants in the NICU

Background

In the neonatal intensive care unit, nurses often place premature infants in the supine, prone, and lateral positions. However, these positions do not always meet all the physiological needs of premature infants. Thus, many improved positions and various position-supporting devices have been studied to provide infants with a development-friendly and comfortable environment.

Aim

We aimed to help nurses recognize and understand the various improved positions and devices, and to provide nurses with more options in addressing the needs of preterm infants.

Study design

We searched PubMed, Web of Science, and EMBASE from 2012 to 2022 for studies on position management of preterm infants, and screened the search results according to inclusion and exclusion criteria. Then we extracted data and evaluated the quality of the included studies. Finally, we conducted a qualitative summary of the results.

Results

Twenty-one articles were included in this review. Fourteen were studies about improved positions, including hammock position, facilitated tucking position, ROP position, reverse kangaroo mother care position (R-KMC), and supported diagonal flexion position (SDF). Seven were studies on positioning devices, four on cranial deformity prevention, and three on reformative swaddling. They have a positive impact on sleep and flexion maintenance, in addition, they can prevent head deformity and reduce the pain of premature infants.

Conclusion

The position management of premature infants is diversified. Instead of sticking to a single position placement, nurses should adjust the position according to the unique physiological conditions of infants to reduce sequelae and promote their recovery and growth during long-term hospitalization. There should be more studies on position management with large sample sizes in the future.

Design and pilot testing of therapeutic clothing for hospitalized children

PURPOSE

The purpose of this paper is to describe the design and pilot program of a parent designed clothing option for hospitalized infants and children and to better understand the importance and effects of hospital clothing on families. Little research has been done on how clothing a hospitalized child impacts the child's quality of life and their parent's perception of care. Research has been limited to clothing in adults and its relation to infection.

DESIGN AND METHODS

A pediatric outfit (the Georgie) for hospitalized infants and children was designed based on insight from bedside nursing, physicians, parents, and supply chain personnel. The garment was pilot tested on select patients from intensive care units of a large children's hospital. A pre- and post-use questionnaire was disseminated with questions focused on aspects of the child's care, comfort in changing child's clothes/diapers, number of times the Georgie was used and comfort level of using the Georgie. Survey responses were summarized using descriptive statistics.

RESULTS

Parents overall response to the Georgie was positive with great value placed on having their child dressed. All parents (n = 5) responded that too many lines were an obstacle to having their child dressed. Compared to the hospital Johnny, the Georgie (80%, n = 4) was the most preferred when placement and securement of monitoring lines was taken into consideration with one parent preferring a blanket and diaper only. Nurses felt the benefit outweighed the added effort in dressing the patient. The majority of the nurses had a positive initial reaction to the Georgie (80%, n = 4) and felt the lines or external devices were "very secure/secure" (80%, n = 4) when the patient was wearing the Georgie.

PRACTICE IMPLICATIONS

Implementing a new family centered care initiative of dressing critically ill patients in the Georgie may improve patient and family's quality of life while hospitalized. A larger scale study is indicated to assess the importance of dressing hospitalized pediatric patients for their families, to clarify the effect on nursing care, to optimize ability to stabilize lines, and to understand logistical issues.

Early movement restriction leads to maladaptive plasticity in the sensorimotor cortex and to movement disorders

Motor control and body representations in the central nervous system are built, i.e., patterned, during development by sensorimotor experience and somatosensory feedback/reafference. Yet, early emergence of locomotor disorders remains a matter of debate, especially in the absence of brain damage. For instance, children with developmental coordination disorders (DCD) display deficits in planning, executing and controlling movements, concomitant with deficits in executive functions. Thus, are early sensorimotor atypicalities at the origin of long-lasting abnormal development of brain anatomy and functions? We hypothesize that degraded locomotor outcomes in adulthood originate as a consequence of early atypical sensorimotor experiences that induce developmental disorganization of sensorimotor circuitry. We showed recently that postnatal sensorimotor restriction (SMR), through hind limb immobilization from birth to one month, led to enduring digitigrade locomotion with ankle-knee overextension, degraded musculoskeletal tissues (e.g., gastrocnemius atrophy), and clear signs of spinal hyperreflexia in adult rats, suggestive of spasticity; each individual disorder likely interplaying in self-perpetuating cycles. In the present study, we investigated the impact of postnatal SMR on the anatomical and functional organization of hind limb representations in the sensorimotor cortex and processes representative of maladaptive neuroplasticity. We found that 28 days of daily SMR degraded the topographical organization of somatosensory hind limb maps, reduced both somatosensory and motor map areas devoted to the hind limb representation and altered neuronal response properties in the sensorimotor cortex several weeks after the cessation of SMR. We found no neuroanatomical histopathology in hind limb sensorimotor cortex, yet increased glutamatergic neurotransmission that matched clear signs of spasticity and hyperexcitability in the adult lumbar spinal network. Thus, even in the absence of a brain insult, movement disorders and brain dysfunction can emerge as a consequence of reduced and atypical patterns of motor outputs and somatosensory feedback that induce maladaptive neuroplasticity. Our results may contribute to understanding the inception and mechanisms underlying neurodevelopmental disorders, such as DCD.
