Infant crying: nature, physiologic consequences, and select interventions

Effects of hydrotherapy and tactile-kinesthetic stimulation on weight gain of preterm infants admitted in the Neonatal Intensive Care Unit

OBJECTIVE

The present study aimed to evaluate the effects of hydrotherapy and tactile-kinesthetic stimulation on the birth weight of preterm infants admitted in the Neonatal Intensive Care Unit.

METHOD

It was a randomized controlled trial, without blinding, in which 44 preterm infants of both sexes with gestational age between 32 and 34 weeks were included into two groups: hydrotherapy group (n = = 22) and tactile-kinesthetic stimulation group (n = 22). Weight gain was the parameter assessed daily.

RESULTS

In the tactile-kinesthetic stimulation group there was a variation in weight gain, but without significant difference (p = 0,43). However, in the hydrotherapy group, it was observed that increased weight gain started from the 2nd day (p < 0,001).

CONCLUSIONS

Hydrotherapy group presented significantly increased weight after the interventions, indicating that this technique can interfere with weight gain in preterm infants.

Effectiveness of Sucrose Used Routinely for Pain Relief and Neonatal Clinical Risk in Preterm Infants: A Nonrandomized Study

BACKGROUND

Preterm infants (PI) requiring the neonatal intensive care unit are exposed to early repetitive pain/distress. Little is known about how pain relief strategies interact with infants' clinical health status, such as severity of illness with pain responses. This study aimed to examine main and interactive effects of routine sucrose intervention and neonatal clinical risk (NCR) on biobehavioral pain reactivity-recovery in PI during painful blood collection procedures.

METHODS

Very low birth weight PI (<1500 g; n=104) were assigned to low and high clinical risk groups, according to the Clinical Risk Index for Babies. Sucrose group (n=52) received sucrose solution (25%; 0.5 mL/kg) 2 minutes before the procedures and control group received standard care. Biobehavioral pain reactivity-recovery was assessed according to the Neonatal Facial Coding System, sleep-wake state scale, crying time, and heart rate at 5 phases (baseline, antisepsis, puncture (P), recovery-dressing, and recovery-resting [R]). Repeated measure ANOVA with mixed-design was performed considering pain assessment phases, intervention group, and NCR.

RESULTS

Independent of NCR, sucrose presented main effect in decreasing neonates' facial activity pain responses and crying time, during P and R. Independent of NCR level or routine sucrose intervention, all neonates displayed activated state in P and decreased biobehavioral responses in R phase. Although no sucrose or NCR effects were observed on physiological reactivity, all neonates exhibited physiological recovery 10 minutes after P, reaching the same heart rate patterns as the baseline.

CONCLUSIONS

Independent of NCR level, sucrose intervention for pain relief during acute painful procedures was effective to reduce pain intensity and increase biobehavioral regulation.

The Effects of Contingent Lullaby Music on Parent-Infant Interaction and Amount of Infant Crying in the First Six Weeks of Life

PURPOSE

The purpose of this study was to examine the effect of a live music intervention provided by the mother on full term infants' amount of crying and parent-infant interaction in the first six weeks of life.

DESIGN AND METHODS

A randomized posttest-only experimental/no-contact control group design was used for this study. A sample of 66 mothers with healthy, newborn infants were recruited. The researcher wrote an original lullaby with each mother in the experimental group and gave instructions as to how to use the lullaby as reinforcement for infant quiet, non-crying behavior. Mother-infant dyads were assessed over a six-week period for infant crying amounts and parent-infant interaction behaviors. Demographic variables, postpartum depression, and value of music were assessed as well to detect associations between variables and groups.

RESULTS

Results indicated that there were significant differences between groups for mean crying time per week and mother-infant interaction behaviors. Analysis by demographic variables such as mother parity, socioeconomic status, and marital status showed no significant group differences on infant crying or interaction scores. Mothers who used the contingent music intervention were more motivated to sing and valued the use of music with their infants more than mothers in the control group.

CONCLUSIONS

The outcomes of this study demonstrate importance of parental singing for mother-infant bonding.

PRACTICE IMPLICATIONS

Implementing early intervention services, such as music therapy in the postpartum unit, can provide new mothers useful music applications that can enhance mother-infant interaction, especially mothers living in high stress or negative environments.

The Effect of Short Duration Skin to Skin Contact on Premature Infants' Physiological and Behavioral Outcomes: A Quasi-Experimental Study

PURPOSE

This study aimed at assessing the effect of short duration Skin to skin contact (SSC) (5 days) on premature infants' short-term physiological and behavioral outcomes.

DESIGN AND METHODS

A quasi-experimental control group design was utilized. 89 stable premature infants were allocated to either an interventional or control group.

RESULTS

Results showed that in comparison to the control group, newborns in the SSC group demonstrated higher weight gain (g/day) from day 3-5 of practicing SSC (53.7 g Vs. 32.6 g; P < .05), experienced significantly fewer numbers of apneas (48% Vs. 33.3%; P = .001), and were less likely to use formula feeding (60% Vs. 90%) and more likely to use mixed feeding (formula and breastfeeding) at discharge (33.3% Vs. 10%). Significant differences were also found in the crying, and sleeping patterns of the infants; infants of mothers who practiced SSC were less likely to cry in a continuous pattern and more likely to experience good sleep than infants in the control group.

CONCLUSIONS

The study highlights the importance of the early and short duration of SSC for premature infants.

PRACTICE IMPLICATIONS

The initiation of SSC in the first few days of life may have a significant influence on the newborn's short-term outcomes.

Impact of infant crying on mothers with a diagnosis of borderline personality disorder: A qualitative study

Mothers with borderline personality disorder (BPD) and their infants often have compromised relationships. To further understand the complexities, this study explored (a) the experiences of mothers with BPD in response to infant crying and (b) how these parenting responses impact on mothers' interpersonal functioning with significant others. Six mothers with clinical BPD were recruited from a mother-baby psychiatric unit and interviewed using an interpretative phenomenological analysis (IPA) approach. Transcripts of the semistructured interviews were coded for themes and subthemes. Dominant themes revealed that mothers with BPD entered motherhood in a psychologically fragile state, hypersensitive to experiencing intense physiological-emotional pain and cognitive chaos in response to infant crying. Automatic maladaptive flight-fright responses including suicide attempts were common. A novel theme revealed some mothers' split identity, and only the "mother" part could attend to infant crying. Finally, the data provided an understanding of the detrimental domino effect on close family. Mothers also highlighted gaps in accessibility of current mental health services and parenting programs, and their desire to prevent the intergenerational transmission of attachment problems and BPD symptoms to offspring. Clinical implications include antenatal BPD screening, psychoeducation about infant crying, and greater access for programs supporting the whole family to improve outcomes.

Olfactive stimulation interventions for managing procedural pain in preterm and full-term neonates: a systematic review protocol

BACKGROUND

While hospitalized in the NICU, preterm neonates undergo many painful procedures. This may be the same for full-term neonates when longer hospitalization is required. Untreated and repeated pain has short-term as well as long-term consequences for these neonates. Pharmacological pain management methods have many limitations in their applications for both preterm and full-term neonates. A combination of different non-pharmacological methods is recommended for pain management. The effect of olfactive stimulation as a non-pharmacological pain management method was investigated by a few studies in the past years with premature and term neonates, but no systematic review has been conducted. The objective of this systematic review is to evaluate the effect of olfactive stimulation intervention on the pain response of preterm and full-term neonates during painful procedures.

METHODS

An electronic search will be conducted in various databases such as PubMed (1946 to date), MEDLINE (1946 to date), CINAHL (1981 to date), Embase (1947 to date), PsycINFO (1806 to date), Web of Science (1945 to date), CENTRAL and Scopus (1960 to date), and Proquest, without restriction for the year of publication. Only studies published in English or French will be included. The search will be conducted using the following three concepts: pain, odors, and neonates. Selection of articles, data extraction, and assessment of risk of bias will be conducted by two independent researchers. A third researcher will intervene in case of disagreement. According to the availability of studies and data homogeneity, the results will be combined to perform a meta-analysis, or they will be described by a narrative synthesis.

DISCUSSION

This systematic review will provide light on the current state of knowledge on the effectiveness of olfactive stimulation interventions for managing pain in preterm and full-term neonates. This review will guide clinical practice as well as research to improve preterm and full-term neonates' pain management and prevent short-term and long-term complications caused by pain.

Pilot study demonstrates that salivary oxytocin can be measured unobtrusively in preterm infants

Aim

This study assessed the feasibility and obtrusiveness of measuring salivary oxytocin in preterm infants receiving Kangaroo care, because this is a period of maximal bonding or co‐regulation. We also analysed possible influential determinants, including maternal oxytocin.

Methods

The saliva of preterm infants and their mothers was collected prior to, and during, Kangaroo care using cotton swabs and pooled into vials until sufficient volumes were obtained to measure oxytocin levels using a radioimmunoassay. The obtrusiveness of the infants’ collections was measured with a Likert scale.

Results

Saliva was collected unobtrusively prior to, and during, 30 Kangaroo care sessions in 21 preterm infants. This resulted in three vials with sufficient volumes of before‐Kangaroo care saliva and three with during‐Kangaroo care saliva. Oxytocin was detectable in all six vials. The Kangaroo care duration and the intensity of the mother–infant interaction before and during Kangaroo care seemed to be the most important determinants, and these should preferably be standardised in any future trials.

Conclusion

Oxytocin was measured unobtrusively in the pooled saliva of preterm infants both before and during Kangaroo care and could therefore be investigated as a biomarker in future studies.

Infant and toddler crying, sleeping and feeding problems and trajectories of dysregulated behavior across childhood

Infant and toddler regulatory problems (RPs) including crying, sleeping and feeding, are a frequent concern for parents and have been associated with negative behavioral outcomes in early and middle childhood. Uncertain is whether infant and toddler RPs predict stable, trait-like dysregulated behavior across childhood. We addressed this gap in the literature using data from the Avon Longitudinal Study of Parents and Children (ALSPAC). RPs at 6, 15-18, & 24-30 months and childhood dysregulated behavior at 4, 7, 8, & 9.5 years were assessed using mother report. Latent Class Growth Analysis (LCGA) indicated that trajectories of childhood dysregulated behavior were stable over time. All single RPs (i.e., crying, sleeping & feeding problems) were significantly associated with childhood dysregulated behavior. For example, crying problems at 6 months after controlling for confounders (Odds Ratios; 95% Confidence Intervals): Moderate dysregulated behavior: OR = 1.50, 95% CI [1.09 to 2.06], high dysregulated behavior: OR = 2.13, 95% CI [1.49 to 3.05] and very high dysregulated behavior: OR = 2.85, 95% CI [1.64 to 4.94]. Multiple RPs were especially strongly associated with dysregulated behavior. For example, the RP composite at 15-18 months: 1 RP, very high dysregulated behavior: OR = 2.79, 95% CI [2.17 to 3.57], 2 RPs, very high dysregulated behavior: OR = 3.46, 95% CI [2.38 to 5.01], 3 RPs, very high dysregulated behavior: OR = 12.57, 95% CI [6.38 to 24.74]. These findings suggest that RPs in infants and toddlers predict stable dysregulated behavior trajectories across childhood. Interventions for early RPs could help prevent the development of chronic, highly dysregulated behavior.

Normal sizes of internal jugular veins in children/adolescents aged birth to 18 years at rest and during the Valsalva maneuver

OBJECTIVES

We aimed to establish normal ultrasonographic (US) values of internal jugular vein (IJV) sizes in children/adolescents aged birth to 18 years and to determine the correlation of US measurements with age, height, weight and body surface area (BSA) of children in different age groups.

METHODS

Two hundred and thirty-six healthy children (0-18 years) were divided into four groups according to their age (0-2, 3-6, 7-12, and 13-18 years). US measurements (transverse, anteroposterior diameter, and cross-sectional area at rest and during the Valsalva maneuver) of bilateral IJVs were taken at the level of cricoid cartilage.

RESULTS

Our study gives information about the reference values in children between birth to 18 years of age. There were significant differences between measurements taken at rest and during the Valsalva maneuver in all age groups. Moderate to strong correlations (clinically significant) between age, height and BSA of the subjects and IJV measurements were detected only in the 0-2 years age group. The strength of the correlations decreased with increasing age. Pearson's correlation revealed that height had the strongest and weight had the weakest correlation with US measurements. 'Height' was an independent variable on the right, and 'age' on the left side, except for rest CSA, when a regression analysis was performed for clinically significant correlations.

CONCLUSIONS

Determination of normal reference values for US measurements of the IJV and knowledge of correlation with age, height, weight and BSA might be valuable during interventional procedures and for the diagnosis of phlebectasia in children/adolescents.

Pain assessment and measurement in neonates: an updated review

Pain assessment and measurement are the cornerstones of pain management. Pain assessment connotes a comprehensive multidimensional description. Conversely, pain measurement provides a numeric quantitative description of each factor illustrating pain qualities. Pain scales provide a composite score used to guide practice and research. The type of infant pain instrument chosen is a significant factor in guiding pain management practice. The purpose of this review was to summarize current infant pain measures by introducing a conceptual framework for pain measurement. Although more than 40 infant pain instruments exist, many were devised solely for research purposes; several of the newly developed instruments largely overlap with existing instruments. Integration of pain management into daily practice remains problematic. Understanding how each instrument measures infant pain allows clinicians to make better decisions about what instrument to use with which infant and in what circumstances. In addition, novel new measurement techniques need further testing.

Spontaneous cries can alter the physiological well-being and cerebral oxygenation of very preterm infants

INTRODUCTION

Infant crying is a major expression of distress and can occur without any exogenous stimulation. Little is known, however, about the effects of crying on physiological homeostasis in very preterm infants (VPIs).

METHODS

Environmental, behavioral (video and audio recording) and physiologic (heart rate [HR], respiratory rate [RR], and systemic [SaO(2)] and regional cerebral oxygenation [rSO(2)]) parameters were prospectively evaluated over 10h in 18 VPIs (median gestational age, 28 [27-31] weeks). Only episodes of "spontaneous" and isolated cries were analyzed. Changes in parameters were compared over 5-second periods between baselines and 40s following the onset of crying. Two periods were distinguished: 0-20s (a) and 20-40s (b). Minimal and/or maximal values in these periods were also compared to the baseline.

RESULTS

Of the 18 VPIs initially studied, 13 (72%) presented crying episodes (CE). They experienced 210 "spontaneous" and isolated CE, with a median of 9 [range, 1-63] CEs per child. Physiological values varied significantly from the baseline with mainly a mean decrease in HR of -4.8±5.3 beats/min (b) after an initial mean increase of +2.6±2.0 beats/min (a); a mean decrease in RR of -3.8±4.8 cycles/min (a), followed by a mean increase of +5.6±7.3 cycles/min (b) and mean unidirectional decreases in SaO(2) and rSO(2) (minimal values) of -1.8±2.3% and -2.5±3.0%, respectively.

CONCLUSION

Spontaneous cries can alter the homeostasis of VPIs. Their possible adverse consequences and high occurrence emphasize the need for better prevention and response to them.

Prospective clinical audit of chloral hydrate administration practices in a neonatal unit

AIM

Chloral hydrate is generally considered a safe and effective single dosing procedural sedative for neonates in the clinical setting. However, its safety profile as a repetitive dosing maintenance sedative is largely unknown. This study aimed to document current administration practices of chloral hydrate in the Neonatal Unit, Royal Children's Hospital, Melbourne, Australia, over a 6-month period.

METHODS

Patients who had been prescribed chloral hydrate during the specified audit period were recruited into the study and prospectively followed for a period of 28 days, or until they were discharged from the unit. Demographic data were collected on recruitment, and daily documentation of chloral hydrate administration was recorded.

RESULTS

A total of 238 doses of chloral hydrate were administered to a cohort of 32 patients during the study period. The majority of the audited doses (84%) were ordered as repeating doses. Doses were more likely to be given at night than during the day, and the median dosage for repetitive dosing was found to be above the study site's recommended dosing range. Pre-dose and/or post-dose assessment of distress/agitation accompanied dosage approximately half of the time. The audit did not reveal any recognisable pattern of sedation maintenance or weaning process for patients who received multiple doses.

CONCLUSIONS

Health-care professionals caring for hospitalised infants should be made aware of the potential risks of chloral hydrate as a repetitive dosing sedative, and of the importance of systematically evaluating the appropriateness and effectiveness of utilising such pharmacological intervention for managing and treating distress.

Early skin-to-skin contact for mothers and their healthy newborn infants

BACKGROUND

Mother-infant separation postbirth is common in Western culture. Early skin-to-skin contact (SSC) begins ideally at birth and involves placing the naked baby, head covered with a dry cap and a warm blanket across the back, prone on the mother's bare chest. According to mammalian neuroscience, the intimate contact inherent in this place (habitat) evokes neurobehaviors ensuring fulfillment of basic biological needs. This time may represent a psychophysiologically 'sensitive period' for programming future physiology and behavior.

OBJECTIVES

To assess the effects of early SSC on breastfeeding, physiological adaptation, and behavior in healthy mother-newborn dyads.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 November 2011), made personal contact with trialists, and consulted the bibliography on kangaroo mother care (KMC) maintained by Dr. Susan Ludington.

SELECTION CRITERIA

Randomized controlled trials comparing early SSC with usual hospital care.

DATA COLLECTION AND ANALYSIS

We independently assessed trial quality and extracted data. Study authors were contacted for additional information.

MAIN RESULTS

Thirty-four randomized controlled trials were included involving 2177 participants (mother-infant dyads). Data from more than two trials were available for only eight outcome measures. For primary outcomes, we found a statistically significant positive effect of early SSC on breastfeeding at one to four months postbirth (13 trials; 702 participants) (risk ratio (RR) 1.27, 95% confidence interval (CI) 1.06 to 1.53, and SSC increased breastfeeding duration (seven trials; 324 participants) (mean difference (MD) 42.55 days, 95% CI -1.69 to 86.79) but the results did not quite reach statistical significance (P = 0.06). Late preterm infants had better cardio-respiratory stability with early SSC (one trial; 31 participants) (MD 2.88, 95% CI 0.53 to 5.23). Blood glucose 75 to 90 minutes following the birth was significantly higher in SSC infants (two trials, 94 infants) (MD 10.56 mg/dL, 95% CI 8.40 to 12.72).The overall methodological quality of trials was mixed, and there was high heterogeneity for some outcomes.

AUTHORS' CONCLUSIONS

Limitations included methodological quality, variations in intervention implementation, and outcomes. The intervention appears to benefit breastfeeding outcomes, and cardio-respiratory stability and decrease infant crying, and has no apparent short- or long-term negative effects. Further investigation is recommended. To facilitate meta-analysis, future research should be done using outcome measures consistent with those in the studies included here. Published reports should clearly indicate if the intervention was SSC with time of initiation and duration and include means, standard deviations and exact probability values.

The effect of a familiar scent on the behavioral and physiological pain responses in neonates

There are adverse physiologic effects of pain in neonates, and effective pain management must be an essential aspect of neonatal care. In this study we assessed the effect of a nonmaternal familiar scent on the neonatal pain responses. This study included 135 neonates randomly assigned to one of three groups. During arterial puncture, one group was exposed to a vanillin scent on a gauze pad held next to their nose. They were familiarized with it the night before blood sampling by a scented gauze pad placed in the incubator next to their head for an average duration of 8.65 hours. The second group was not familiarized with the scent but was exposed to it during the procedure. The third group was neither familiarized nor exposed to the scent. The duration of crying in the familiar scent group was significantly lower than in the two other groups. Comparison of the physiologic parameters showed less variation in oxygen saturation level during arterial puncture in the familiar scent group. In this study, a familiar scent could reduce crying and oxygen consumption during arterial puncture.

Randomized crossover trial of kangaroo care to reduce biobehavioral pain responses in preterm infants: a pilot study

Kangaroo care (KC), skin-to-skin contact between mother and infant, is a promising method for blunting pain responses. This crossover pilot tested KC effects on biobehavioral responses to heel stick in preterm infants (30-32 weeks' gestational age, 2-9 days old) measured by Premature Infant Pain Profile (PIPP) and salivary and serum cortisol. Mother-infant dyads were randomly assigned to KC heel stick (KCH) first or incubator heel stick (IH) first. Study 1 (80-min study, N = 18) tested the effect of 80 min of KC before and throughout the heel stick procedure versus incubator care. Study 2 (30-min study, N = 10) tested 30 min of KC before and throughout the heel stick versus incubator care. KCH and IH began during a premeasurement phase and continued through four data collection phases: baseline, heel warming, heel stick, and recovery. PIPP responses were measured every 30 s during data collection; salivary cortisol was measured at the end of baseline and recovery; and serum cortisol was measured during heel stick. Study 1 showed no differences between KCH and IH. Study 2 showed lower PIPP scores at four time points during recovery (p < .05 to p < .001), lower salivary cortisol at the end of recovery (p < .05), and lower serum cortisol during heel stick for the KCH condition (p < .05) as well as clinically lower PIPP scores in the KCH condition during heel stick. Thirty minutes of KC before and throughout the heel stick reduced biobehavioral responses to pain in preterm infants.

O contato pele a pele ao nascimento e o choro de recém-nascidos durante vacinação contra Hepatite B

OBJETIVO: Testar a efetividade do contato pele a pele entre mãe e filho após o nascimento na redução do comportamento de estresse/dor manifestado pelo choro do recém-nascido (RN), decorrente do procedimento de vacinação contra a Hepatite B. MÉTODOS: Estudo comparativo quase-experimental abrangendo 40 RN a termo, divididos em dois grupos, com ou sem contato pele a pele com suas mães após o nascimento, e que foram comparados quanto ao tempo de choro durante a vacinação contra Hepatite B. RESULTADOS: Variações no tempo de choro foram observadas nos dois grupos durante as fases desse procedimento. CONCLUSÃO: O efeito do contato na diminuição do tempo de choro dos RN, não foi demonstrado estatisticamente. Clinicamente, a Síndrome do Chamado pelo Estresse foi observada, bem como a efetividade do período de contato, na modulação do comportamento de choro dos neonatos, enquanto estes estiveram sob o momento terapêutico.

Rapid eye movement (REM) in premature neonates and developmental outcome at 6 months

Different aspects of early sleep organization have been associated with subsequent development in premature infants. The aim of the present study was to assess the relations between rapid eye movement (REM) activity in premature neonates and infants' developmental outcomes at 6 months. Participants were 81 premature infants (47 males). Sleep-wake states and REM were observed across 4 consecutive evening hours (7-11 PM) in 10-s frames when infants were between 32 and 36 weeks post-menstrual age. Developmental outcome was assessed at 6 months with the mental development index (MDI) of the Bayley II. Infants with low-REM activity spent more time in less growth-promoting states, including crying and unfocused alert states in the neonatal period and had lower MDI scores at 6 months corrected age compared to infants with high-REM. Differences between the high- and low-REM groups were independent of neonatal medical risk. Low-REM activity may serve as an indicator of developmental risk among premature neonates.

Kangaroo Care (skin contact) reduces crying response to pain in preterm neonates: pilot results

Crying commonly occurs in response to heel stick and adversely affects the infant's physiologic stability. Minimal crying in response to pain is desired. "Kangaroo Care," skin contact between mother and infant, reduces pain and may reduce crying in response to pain. The purpose of this pilot study was to test Kangaroo Care's effect on the preterm infant's audible and inaudible crying response to heel stick. Inaudible crying has not been previously studied. A prospective randomized cross-over study with 10 preterm infants 2-9 days old (30-32 weeks' postmenstrual age) was conducted. Infants were randomly assigned to two sequences (sequence A: day 1 heel stick in Kangaroo Care [after 30 min of prone skin contact upright between maternal breasts] and day 2 heel stick in incubator [inclined, nested and prone]; or sequence B: opposite of sequence A) was conducted. Videotapes of baseline, heel warming, heel stick, and recovery phases were scored for audible and inaudible crying times. Audible and inaudible crying times for each subject in each phase were summed and analyzed by repeated-measures analysis of variance. Subject characteristics did not differ between those in the two sequences. Crying time differed between the study phases on both days (p <or= .001). When in Kangaroo Care compared with the incubator, crying time was less during the heel stick (p = .001) and recovery (p = .01) phases, regardless of sequence. Because Kangaroo Care reduced crying in response to heel stick in medically stable preterm infants, a definitive study is merited before making recommendations.

Interação mãe-bebê pré-termo e mudança no estado de humor: comparação do Método Mãe-Canguru com visita na Unidade de Terapia Intensiva Neonatal

OBJETIVO: avaliar mudanças nos estados de humor de mães de bebês pré-termo em função do tipo de contato com o seu filho: Método Mãe-Canguru (MMC) e visita ao filho na incubadora da Unidade de Terapia Intensiva Neonatal. MÉTODOS: foi aplicada a Escala Analógica de Humor em 60 mães divididas em 2 grupos: mães que participam do Método Mãe-Canguru (GC) e mães que acompanharam o bebê na incubadora (GI). Os grupos foram pareados em função da idade das mães, número de gestações e tipo de parto. As mães foram avaliadas antes e depois de uma das visitas ao filho na incubadora ou sessão de MMC. RESULTADOS: as mães do GC melhoraram o humor, relatando: sentirem-se mais calmas, fortes, com idéias claras, ágeis, dinâmicas, satisfeitas, tranqüilas, perspicazes, relaxadas, atentas, competentes, alegres e amistosas. As mães do GI não apresentaram melhora no estado de humor em nenhum item, mas pioraram no item "sentindo-se desajeitada". CONCLUSÕES: o Método Mãe-Canguru mostrou-se eficaz na melhora nos estados de humor de mães de bebês pré-termo, contribuindo assim para a minimização dos efeitos negativos da internação neonatal.

Dimensions of internal jugular veins in Turkish children aged between 0 and 6 years in resting state and during Valsalva maneuver

OBJECTIVE

We aimed to establish the values of the internal jugular vein (IJV) sizes in Turkish children aged between 0 and 6 years.

METHODS

Ninety-four normal children included in this study. All of the children were imaged by ultrasonography (USG) at the level of the cricoid cartilage. The maximal antero-posterior (AP) and transverse (T) diameters of the IJV were measured during regular breathing and Valsalva maneuver.

RESULTS

The mean transverse diameter of the right and left IJV were 8.11+/-3.01 and 7.64+/-2.68 mm in resting state. These values changed to 12.57+/-4.34 and 10.82+/-3.80 mm in Valsalva state, respectively. The AP diameters were found to be 5.43+/-2.07 for the right and 5.86+/-4.53 mm for the left IJV at rest. During VM, these values changed to 8.70+/-2.40 and 8.30+/-2.90 mm for the right and left IJV, respectively. There was no significant difference on the evaluation of the relationship between the right and left diameters of the IJV. While there were significant differences in sizes between the resting and Valsalva states. Also, the T diameter of the right IJV during Valsalva state was greater than those of the left. There were significant correlations between the diameters of the IJV and the age, weight and height of the children.

CONCLUSION

The results we obtained in this study may be important in an attempt of intravascular intervention to IJV. These values may also be important for the comparison with the IJV sizes of the patients who have phlebectasia.

Natural Parenting — Back to Basics in Infant Care

This review examines an age-old approach to parenting recently rediscovered in Western industrialized societies and known by names such as natural parenting, attachment parenting, and instinctive parenting. Its leading principle is utmost sensitivity to the child's innate emotional and physical needs, resulting in extended breastfeeding on demand, extensive infant carrying on the caregiver's body, and cosleeping of infant and parents. The described practices prevailed during the evolutionary history of the human species and reflect the natural, innate rearing style of the human species to which the human infant has biologically adapted over the course of evolution. An overview of research from diverse areas regarding psychological as well as physiological aspects of early care provides evidence for the beneficial effects of natural parenting. Cross-cultural and historical data is cited to reveal the widespread use of the investigated parenting style. It is concluded that the described approach to parenting provides the human infant with an ideal environment for optimal growth both psychologically and physiologically. It is yet to be determined how much departure from this prototype of optimal human parenting is possible without compromising infant and parental wellbeing. The review also invites a critical reevaluation of current Western childrearing practices.

A review of nursing interventions to foster becoming a mother

OBJECTIVE

To determine the current state of knowledge of nursing interventions that foster the process of becoming a mother.

DATA SOURCES

A literature search was conducted using CINAHL and PubMed electronic databases and other key references.

STUDY SELECTION

Reports on nursing intervention research published in English that focused on a facet of maternal behavior in the process of becoming a mother during pregnancy or during the first 4 months following birth, or both, were included. Twenty eight reports were found.

DATA EXTRACTION

Studies were reviewed, categorized, and analyzed and interventions synthesized to determine the current knowledge base for fostering becoming a mother. Categories included instructions for infant caregiving, building awareness of and responsiveness to infant interactive capabilities, promoting maternal-infant attachment, maternal/social role preparation, and interactive therapeutic nurse-client relationships.

DATA SYNTHESIS

Interactive therapeutic nurse-client relationships and maternal/social role preparation had greater impact on variables indicating progress in becoming a mother than formal teaching. Instructions without nurse input were ineffective.

CONCLUSIONS

Interactive reciprocal nursing interventions are the most effective in enhancing mother-infant interactions and maternal knowledge about infant care. Evidence is limited on how to foster the mother's feelings about herself in becoming a mother and attachment to her infant.

Método Mãe-Canguru

Estudo de natureza qualitativa, cujo objetivo é o de identificar o conhecimento que vem sendo produzido e veiculado a respeito do Método Mãe-Canguru (MMC). Foi realizada uma incursão pela literatura, a partir das bases de dados Medline e Lilacs, assim como busca direta aos principais periódicos de enfermagem, durante o período de 1995 a 2004. Foram selecionados 85 artigos, posteriormente catalogados e submetidos à categorização. Após análise dos artigos, foram extraídas quatro categorias sobre a temática. Os resultados levaram à conclusão de que apesar do MMC estar configurando-se como uma mudança paradigmática no cuidado ao recém-nascido, não há total correspondência com a produção teórica, levando a que a prática seja desenvolvida, muitas vezes, sem a devida sustentação teórica. Esta lacuna de conhecimentos dificulta, inclusive, uma adequada avaliação desta prática com relação ao recémnascido e sua família, mas principalmente no que diz respeito à aplicação do MMC junto à equipe neonatal.

Skin-to-Skin Contact (Kangaroo Care) Analgesia for Preterm Infant Heel Stick

The purpose of the study was to compare a heel stick conducted during Kangaroo Care (skin-to-skin contact) with the mother to a heel stick in a warmer in reducing premature infant physiologic and behavioral pain responses. Twenty-four premature infants in a university-based neonatal intensive care unit were recruited and randomized to 2 sequences: sequence A group received 3 hours of Kangaroo Care (with a heel stick in Kangaroo Care) followed by 3 hours in a warmer (with a heel stick in the warmer). Sequence B group had warmer care and a heel stick (in the warmer) before Kangaroo Care and a heel stick (in Kangaroo Care). Heart rate, respiratory rate, oxygen saturation, crying time, and behavioral state were measured before, during, and after heel stick. Repeated measures ANOVA and Mann Whitney U statistics were performed. Heart rate and length of crying in response to pain were significantly reduced during Kangaroo Care and the Kangaroo Care heel stick as compared to when infants were in the warmer and had a heel stick in the warmer. Three infants did not cry at all during the Kangaroo Care heel stick; infants slept more during Kangaroo Care than in the warmer. Kangaroo Care positioning before and during heel stick is a simple and inexpensive analgesic intervention to ameliorate pain in stable premature infants.

Kangaroo Mother Care: 25 years after

The components of the Kangaroo Mother Care (KMC) intervention, their rational bases, and their current uses in low-, middle-, and high-income countries are described. KMC was started in 1978 in Bogotá (Colombia) in response to overcrowding and insufficient resources in neonatal intensive care units associated with high morbidity and mortality among low-birthweight infants. The intervention consists of continuous skin-to-skin contact between the mother and the infant, exclusive breastfeeding, and early home discharge in the kangaroo position. In studies of the physiological effects of KMC, the results for most variables were within clinically acceptable ranges or the same as those for premature infants under other forms of care. Body temperature and weight gain are significantly increased, and a meta-analysis showed that the kangaroo position increases the uptake and duration of breastfeeding. Investigations of the behavioral effects of KMC show rapid quiescence. The psychosocial effects of KMC include reduced stress, enhancement of mother-infant bonding, and positive effects on the family environment and the infant's cognitive development.

CONCLUSION

Past and current research has clarified some of the rational bases of KMC and has provided evidence for its effectiveness and safety, although more research is needed to clearly define the effectiveness of the various components of the intervention in different settings and for different therapeutic goals.

Newborns in adverse conditions: issues, challenges, and interventions

Neonatal mortality is intolerably high in developing countries and in situations of crisis or disaster as a result of inequity, poverty, and lack of health care services. A series of effective, low-cost interventions, based on appropriate technologies can be used to address the main causes of neonatal deaths. Among these interventions, promotion of exclusive breastfeeding and thermal control of the newborn infant are very effective ones. Although the effectiveness of interventions such as kangaroo mother care, newborn resuscitation, and infant massage is not widely recognized, they may have important complementary roles in providing heath care to newborn infants in adverse conditions.

Sleeping beauties: the impact of sedation on neonatal development

Sedatives are frequently administered in neonatal intensive care to induce sleep for diagnostic and radiology procedures, calm irritable infants, manage pain-related agitation, and enhance ventilation. The pharmacology and side effects of sedatives commonly used with neonates will be reviewed and placed within the context of their potential effect on neonatal development. Alternative caregiving strategies to minimize or eliminate the need for sedation will be discussed.
