“…All of the infants were sedated. [27][28][29] Heart rate and oxygen saturation were monitored, and an experienced neonatologist was always present. Standard T1-and T2-weighted spin-echo and often diffusion-weighted images were obtained.…”

BACKGROUND AND PURPOSE:Brain imaging is an integral part of the diagnostic work-up for metabolic disorders, and the bedside availability of cranial ultrasonography (cUS) allows very early brain imaging in symptomatic neonates. Our aim was to investigate the role and range of abnormalities seen on cUS in neonates presenting with metabolic disorders. A secondary aim, when possible, was to address the question of whether brain MR imaging is more informative by comparing cUS to MR imaging findings.

“…They are exposed to gravity before their bodies can deal with it and are forced to live and cope in an environment different from the protected environment in the uterus. They do not exhibit adequate flexor tone, which is normally exhibited by full-term infants, and even when they reach their full-term, they often show extended posture 3,4) . Full-term infants experience non-nutritive sucking as they are tucked in the flexion posture in the uterus.…”

The Influence of Positioning on Spontaneous Movements of Preterm Infants

Abstract. [Purpose] In this study, we quantitatively evaluated how the positioning program influenced the movement patterns of preterm infants in the neonatal intensive care unit (NICU). [Subjects and Methods] Spontaneous movements of 12 low-risk preterm infants were video-recorded at 38 or 39 postmenstrual weeks of age (PMA). Six of them (positioning group) received a positioning program from birth to 35-36 weeks of PMA while the other 6 (non-positioning group) did not. We attached reflective markers on the infant's wrists and ankles in the supine position and filmed them from above. By using a two-dimensional image analysis system, we digitized the wrist and ankle trajectories and analyzed the data by calculating several statistics.[Results] Infants in the positioning group brought their hands to the midline or crossed their hands over the midline and showed more variation in velocity of movements than those in the nonpositioning group. We also noticed that infants in the positioning group exhibited and maintained a movement pattern similar to that of full-term infants at 1 month after the positioning program was terminated.[Conclusions] These results suggest that appropriate positioning of preterm infants facilitates flexion posture and movement patterns toward the centre of the body similar to foetuses in the uterus.

“…PNBs at term do not exhibit the same development patterns as term newborns do. This impairment manifests itself in the newborns' incapacity to perform postural adjustments, owing to their low muscle tone and the immaturity of their organization systems [4][5][6] . Another important item that distinguishes PNBs at term from term newborns is their primitives reflexes responses.…”

“…Procedures This is a prospective neonatal study, using the SDS 8 to assess and describe the first neurological examination of the selected PNBs. The SDS assesses neurological patterns by [1] evaluating states of awareness classified as sleepiness, provoked wakefulness, spontaneous wakefulness, alternating wakefulness and sleep, and sedation; [2] assessing bed posture; [3] evaluating motor and neonatal reflexes through the assessment of cardinal point reflexes, finger squeezes, Moro reflexes, cross extensions reflexe and the automatic walking reflexes; [4] resistance to passive movements through of popliteal, foot-leg, and heel-to-ear angles; and [5] assessing active muscle tone through the evaluation of spontaneous movements, lower limbs straightenings, head straightenings, and the examination of neck flexor muscles (traction maneuver). During the application of the SDS, the head circumference (HC) was measured.…”

Objective: To describe the maturational development of 20 (aged 32-36 weeks) premature newborns (PNBs) without clinical or neurological complications from birth until term. Method: The Saint-Anne Dargassies Scale was applied every two weeks until the age of 37 weeks. Results: The PNBs showed normal Apgar and the growth in head circumference was adequate for postmentrual age. The Friedman ANOVA test found a significant difference only for the heel-to-ear angles from birth until term. The Saint-Anne Dargassies Scale detected changes in 11 PNBs and the most altered reflexes were: cardinal points, Moro, cross extension reflexe and automatic walking. These changes were found in the first 48 hours of life and in subsequent weeks until term. Conclusion: This finding alone justifies the neurological examination of PNBs, even if they show no clinical/neurological complications in the perinatal period and the importance of neuromotor assessment in preterm infants, as it enables detection and appropriate intervention. Key words: preterm newborn, Saint-Anne Dargassies Scale, neonatal neurological examination.O exame neurológico de recém-nascidos prematuros não complicados do nascimento ao termo pela escala de Saint-Anne Dargassies RESUMO Objetivo: Descrever a evolução maturacional de prematuros sem complicações clínicas ou neurológicas (RNP) do nascimento até atingir o termo. Método: A escala de SaintAnne Dargassies foi aplicada a cada duas semanas até atingir a idade de 37 semanas, considerado termo pela autora. Resultados: Os recém-nascidos prematuros apresentaram APGAR normal após a reanimação não invasiva e o crescimento do perímetro cefálico foi adequado à idade concepcional. O teste de Friedman ANOVA detectou diferenças significativas apenas para o ângulo calcanhar-orelha do nascimento ao termo. A escala de Saint-Anne Dargassies detectou 11 RNP com alterações nos reflexos: dos pontos cardinais, Moro, alargamento cruzado e o de marcha automática. Estas alterações foram encontradas nas primeiras 48 horas de vida e nas semanas subseqüentes até atingir o termo. Conclusão: Este achado por si justifica o exame neurológico de RNP mesmo que eles não apresentem complicações clínicas/neurológicas no período peri-natal, e mostra que é importante a avaliação neuromotora nos prematuros, pois isso viabiliza a detecção e intervenção adequadas. Palavras-chave: recém-nascidos prematuros, escala de Saint-Anne Dargassies, exame neurológico neonatal.
