Immature sucking patterns in infants of mothers with diabetes.

OBJECTIVE: To evaluate immaturity of sucking patterns of infants of mothers with diabetes. STUDY DESIGN: Term infants born to mothers with gestational diabetes mellitus (16 mothers managed with insulin and 31 with diet alone) were compared with 55 matched healthy infants (control group). Sucking patterns were recorded and analyzed for number of sucks and bursts and averages maximum suck pressure, number of sucks per burst, suck width, and time between bursts. The measurements were made for feedings of 5 minutes duration with Kron's Nutritive Sucking Apparatus on the third day of life. RESULTS: Relative to the control group, newborns of the insulin-treated mothers averaged 5.2 fewer bursts and 42 fewer sucks (P = .013 and P = .04, respectively). No differences were noted for other variables tested. There were no differences in sucking patterns between newborns of diet-managed mothers and control newborns. CONCLUSION: Poorer sucking patterns were found among infants of insulin-managed mothers with diabetes. The present findings indicate some degree of neurologic immaturity during the early neonatal period.

Comparison of sucking patterns at introduction of oral feeding and at term in Israeli and American preterm infants.

BACKGROUND: It has been hypothesized that early initiation of oral feeding in premature infants may enhance the maturation of sucking patterns. AIM: To compare preterm infant sucking characteristics in urban level III neonatal care units in the USA and Israel. The two hospitals have different practices regarding the introduction of oral feeding. METHODS: Infants were assessed at 34-35 wk postconceptional age (PCA) and at term. Sucking parameters were assessed with the Kron's Nutritive Sucking Apparatus. RESULTS: 70 infants (38 Americans and 32 Israelis) participated in the study. Oral feedings were initiated earlier (32.6 +/- 4.3 vs 34.5 +/- 1.8 wk PCA, p < 0.01) and full oral feedings were reached earlier (35.4 +/- 2.8 vs 36.5 +/- 2.5 wk PCA, p < 0.05) in the USA infants. American preterm infants produced significantly more sucks (p < 0.001), had a higher suck rate (p < 0.001), more sucks per burst (p < 0.05), and a shorter interburst width (p < 0.01) at 34 wk PCA than Israeli infants. At term, American infants produced significant more sucks (p < 0.001), higher suck rate (p < 0.001), shorter intersuck width (p < 0.001), and a shorter interburst width (p < 0.05) than the Israeli infants of the same PCA. CONCLUSION: Different practices in the care of preterm infants, such as postconceptional age at introduction of oral feeding, may play a role in the development of feeding and feeding organization at term.

Feeding patterns of full-term and preterm infants at forty weeks postconceptional age.

Little research exists that addresses the differences in feeding skills between preterm (PT) infants at term and full-term (FT) infants. The purpose of this study was to quantify and examine the differences in sucking abilities of PT infants when measured at 40 weeks postconceptional age (PCA) and newly born FT infants. The sample consisted of 213 infants who were divided into three groups on the basis of their gestational age at birth (24-29 wk, 30-32 wk, and 38-42 wk). The Kron Nutritive Sucking Apparatus (KNSA) was used to examine the microstructure of sucking and feeding behaviors. There were significant differences among the three groups in several of the sucking variables: number of bursts (p = .005), intersuck interval (p = .0212), sucks per burst (p = .0003), suck width (p < .0001), intersuck width (p < .0001), mean maximum pressure (p < .0001), and intersuck width/interburst width (p = .02). The findings from this study demonstrate the importance of both maturation at birth and experience as factors influencing feeding behaviors.

Temperament characteristics of premature infants in the first year of life.

Parenting preterm infants in the first months after hospital discharge is challenging. Although preterm infants are considered to be difficult, preterm temperament at less than 3 months is unknown empirically. The purpose of this analysis was to investigate the 6-week temperament characteristics of preterm infants in comparison with standardized norms of full-term infants. The sample of 74 infants with gestational ages at birth between 24 and 32 weeks were enrolled in a study of preterm infant neurobehavioral outcomes. Mothers rated temperament at 6 weeks, 6 months, and 12 months of age (adjusted for prematurity). At 6 weeks the premature infants were significantly less rhythmic (regular), more distractible (soothable), less approaching (more withdrawing), and less intense than standardized norms for full-term infants. From these data we conclude that premature infants may be initially more challenging to parent. Temperament moderated over time but remained significantly lower in persistence at 12 months. Considerable change in temperament in the first 12 months of life may be influenced by biological and environmental factors common to the premature birth experience.

Nutritive sucking research: from clinical questions to research answers.

Nutritive sucking and feeding behaviors have the potential to predict developmental outcomes. Research is beginning to connect nutritive sucking behaviors and neurodevelopmental outcomes, providing an important understanding of how infants develop during the first year of life. A program of research has evolved using sucking behaviors as the primary indices of both maturation and development in preterm infants. Clinical questions were the guiding force behind 5 funded grants from the National Institutes of Health and many small grants from foundations and professional organizations. Three of the National Institutes of Health studies were research based and 2 were for development of the feeding instrumentation. These cumulative grants have generated a significant volume of data; highlights and clinical implications of this work are presented in this article.

Development of preterm infants: feeding behaviors and brazelton neonatal behavioral assessment scale at 40 and 44 weeks' postconceptional age.

The purpose of this study was twofold: (1) to explore potential changes in the Brazelton Neonatal Behavioral Assessment Scale (BNBAS) from 40 to 44 weeks postconceptional age (PCA) and (2) to determine the relationship between the BNBAS scores and feeding behaviors in preterm infants at 40 and 44 weeks PCA. The BNBAS and sucking behavior measurements were completed on 104 preterm infants at 40 and 44 weeks PCA. The Orientation (p = .001), Motor (p = .001), Range of State (p = .001), Autonomic Regulation (p = .01), and Reflexes (p = .00) clusters were significantly more mature at 44 weeks PCA than at 40 weeks. Infants that were extremely early born (n = 24) had a significantly larger change in BNBAS scores over time as compared to the more mature preterm infants (n = 77), largely catching up with their more mature preterm counterparts. At 40 and 44 weeks PCA, the BNBAS cluster scores for orientation (p = .02), motor (p = .048), range of state (p = .048), and regulation of state (p < .001) were significantly related to the average maximum pressure, adjusted for gestational age and weeks PCA. Significant neurobehavioral maturation takes place between 40 and 44 weeks PCA in preterm infants, with the greatest changes occurring in the most preterm infants. These findings highlight the relationship between neurobehavioral maturation and feeding behaviors.

The AWHONN Near-Term Infant Initiative: a conceptual framework for optimizing health for near-term infants.

In June 2005, the Association of Women's Health, Obstetric and Neonatal Nurses launched a multiyear initiative to address the unique physiologic and developmental needs of near-term infants (NTIs) defined as those born between 34 and 37 weeks post-menstrual age. The Optimizing Care for the Near-Term Infant Conceptual Model integrates the concepts of neonatal physiologic functional status, nursing care practices, care environment, and the essential role of the family both in the hospital and beyond. The elements of the model will serve to guide program and resource development within the Near-Term Infant Initiative. Goals of the initiative are to raise awareness of the NTI population's unique needs, emphasize the need for research, encourage development and adoption of evidence-based guidelines to promote safe care, and provide resources that assist nurses and other health care professionals in risk-based assessment of NTIs.

What are the responses & needs of mothers of infants diagnosed with congenital heart disease?

This article addresses the needs of families of newborns with congenital heart disease (CHD). Approximately 40,000 infants are born with a congenital heart defect each year; a large percentage survive due to technological advances in treatment, resulting in an increasing number of families who have a child living with a chronic illness. While both parents are significantly affected by a diagnosis of CHD, much of the available literature discusses the experience of mothers. The mother's experiences after learning her child's diagnosis include grief, loss of her imagined healthy child, lack of knowledge of the disease, anger, and difficulty in caregiving, among other issues. Support and encouragement at the time of diagnosis and throughout each stage of the illness are essential. This article describes various strategies that nurses can use to assist these families through their difficult journey.
