Purpose: The purpose of this study was to investigate the effects of a breastfeeding support program (BSP) on the prevalence of exclusive breastfeeding and growth in late-preterm infants. Methods: A quasi-experimental study was conducted. The participants were 40 late preterm infants (LPIs), of whom 20 were assigned to the experimental group and 20 to the control group. For the mothers in the experimental group, a BSP was provided prior to the LPIs' discharge and reinforced once a week for 4 weeks. Information on the feeding type was collected by observation and the LPIs' body weight was measured. Results: There were significant differences in feeding type by group and time. Exclusive breastfeeding was 5.18 times more common in the experimental group than in the control group (odds ratio=5.18, 95% confidence interval=1.11~16.70). However, weekly weight gain did not show a significant relationship with group and time (F=0.40, p=.712). Conclusion: The BSP was helpful for increasing the rate of exclusive breastfeeding in LPIs. Furthermore, the LPIs in the experimental group, which had a higher likelihood of being exclusively breastfed, showed an equivalent amount of weight gain as the LPIs in the control group, in which infants were more likely to be formula-fed.

Purpose: A quasi-experimental study was performed to investigate the effects of a home visiting discharge education program on the maternal self-esteem, attachment, postpartum depression and family function in 35 mothers of neonatal intensive care unit (NICU) infants. Methods: Twenty-three mothers in the intervention group received the home visiting discharge education while 12 mothers in the control group received the routine, hospital discharge education. Baseline data was collected in both groups one day after delivery. The intervention group received the home visiting discharge education while the control group did the routine hospital-based discharge education. The questionnaire including the data on maternal self-esteem, attachment, postpartum depression and family function were collected within 1 week after the discharge by mail. Results: The scores of maternal self-esteem, and attachment were significantly increased, and the postpartum depression and the family function score were decreased after the home visiting discharge education in intervention group. There were no changes in these variables before and after the routine hospital-based discharge education in control group. Conclusion: These results support the beneficial effects of home visiting discharge education on the maternal role adaptation and family function of the mothers of NICU infants.

Purpose:　The purpose of this study was to investigate the effects of Yakson therapy conducted by mother of preterm infants on the maternal attachment and attachment behavior. Method: A quasi experimental pre-post test design was used. The data were collected from January, 2005 to October, 2005. The participants were 30 mothers of preterm infants hospitalized in a neonatal intensive care unit (15 in the Yakson therapy group and 15 in control group). Yakson therapy consists of three phases: laying a hand, caressing by hand, and laying a hand again taking 5 minutes for each phase. Yakson therapy was provided to infants in the experimental group for 15-minutes 5 times for 15 days. Data were analyzed using the SAS program with x2-test, repeated measures ANOVA, and Fisher's exact test. Result: Compared to the control group, the experimental group had significantly higher scores in maternal attachment (F=5.54, p=.0258). And the attachment behavior of the experimental group was higher than that of the control group. Conclusion: The results suggest that Yakson therapy can be used to improve maternal attachment and attachment behavior.

Purpose: This study examined the effects of a breastfeeding coaching program for mothers on growth and neonatal jaundice in late preterm infants (LPIs). Methods: This was a quasi-experimental study (non-randomized intervention) with a time-series design. The study was conducted among 40 LPIs who were admitted to the neonatal intensive care unit of a university hospital in Daegu, South Korea. In the order of admission, the first 21 infants were assigned to the experimental group, and 19 were assigned to the control group. The intervention program consisted of home- based and web-based practical breastfeeding support education for mothers across a total of 5 sessions. Infant growth was measured using body weight, length, and head circumference, and neonatal jaundice was assessed using transcutaneous bilirubin levels. Results: The likelihood of breastfeeding for infants in the experimental group at 4 weeks after discharge was the same as on the day of discharge, whereas it steadily decreased in the control group. There were significant differences in head circumference between the groups. However, weight, length, and transcutaneous bilirubin levels did not show a significant group-time interaction. Conclusion: A formal breastfeeding coaching program should be considered in clinical settings and at home within the first few weeks postpartum.

Purpose: This study was conducted to evaluate the effect of breast milk olfactory stimulation on physiological responses, oral feeding progression, and body weight in preterm infants. Methods: A repeated measures design with nonequivalent control group was used. The participants were healthy, preterm infants born at a gestational age of 28~32 weeks; 12 in the experimental group and 16 in the control group. Data were collected prospectively in the experimental group, and retrospectively in the control group, by the same methods. Breast milk olfactory stimulation was provided 12 times over 15 days. The data were analyzed using the chi-square test, Mann-Whitney U test, Wilcoxon signed rank test and linear mixed models using SPSS 19. Results: The gastric residual volume (GRV) of the experimental group was significantly less than that of the control group. The heart rate, oxygen saturation, respiration rate, transition time to oral feeding, and body weight were not significantly different between the two groups. Conclusion: These findings indicate that breast milk olfactory stimulation reduces GRV and improves digestive function in preterm infants without inducing distress.

Newborn infants, including premature infants, are high-risk patients susceptible to various microorganisms. Catheter-related bloodstream infections are the most common type of nosocomial infections in this population. Regular education and training of medical staffs are most important as a preventive strategy for central line-associated bloodstream infections (CLABSIs). Bundle approaches and the use of checklists during the insertion and maintenance of central catheters are effective measures to reduce the incidence of CLABSIs. Chlorhexidine, commonly used as a skin disinfectant before catheter insertion and dressing replacement, is not approved for infants <2 months of age, but is usually used in many neonatal intensive care units due to the lack of alternatives. Chlorhexidine-impregnated dressing and bathing, recommended for adults, cannot be applied to newborns. Appropriate replacement intervals for dressing and care sets are similar to those recommended for adults. Umbilical catheters should not be used longer than 5 days for the umbilical arterial catheter and 14 days for the umbilical venous catheter. It is most important to regularly educate, train and give feedback to the medical staffs about the various preventive measures required at each stage from before insertion to removal of the catheter. Continuous efforts are needed to develop effective and safe infection control strategies for neonates and young infants.

Objectives: Parents of a premature baby feel a pressure on their baby's growth and they are highly in need for proper education. However, the lack of proper education can cause the difficulty of follow-up care and rehospitalization. Currently, methods of education among each nurse are based on verbal explanation and can be often different. Therfore, it is true that the psychological burden is great during education. Hence, by enforcing discharge education activities, we intend to provide information; induce participation of parents; promote the level of performance; standardize education program; and increase the job satisfaction of nurses. Methods: NICU conducted a questionnaire survey of the demand and satisfaction for discharge education among mothers that left hospital. And before and after the improvement activity, the satisfaction level of mothers and nurses were studied, and rehospitalization rate were analyzed. Results 1)The survey results of the satisfaction level of mothers towards education program as followes: The level of understanding of content, general babysitting, special situation, education method, and educator attitude showed statistically significant increase. 2)The survey results of the satisfaction level of nurses towards education program as followes: While, the need for education program decreased, the adequacy of education content and method, consistency of education, understanding of learner, and learner's performance increased. All the factors except for the need for education program and the adequacy of education content showed statistically significant difference. 3)Rehospitalization rate of premature babies decreased. According to analysis of the cause of rehospitalization, breast-feeding related apnea turned out to be the highest. Conclusion: Through QI, satisfaction of mothers and nurses improved more than 10%. And rehospitalization rate of premature babies decreased by the same amount as well. Therefore, with the help of the standardized discharge education program, mothers who is not easy to take care of after leaving hospital can be seen to significantly affect their healthy growth and development.

A descriptive exploratory design was used in this study to evaluate the effects of sponge bathing on physiological(heart rate, heart period, vagal tone, oxygen saturation, respiration) and behavioral responses in newly born 40 preterm infants from intensive care unit of S University Hospital in Seoul. Data has been collected from October, 1997 to March, 1999. The infants were between 27-33 weeks gestational age at birth, and were free of congenital defects. The subjects entered the protocol when they were medically stable (determined by initiation of feeding and discontinuation of all respiratory support) but still receiving neonatal intensive care. The infants' physiologic parameters were recorded a 10 - minute before, during, and after bathing. Continuous heart rate data were recorded on a notebook computer from the infant's EKG monitor. The data were digitized off-line on software(developed by Lee and Chang in Wavelet program) which detected the peak of the R wave for each heart beat and quantified sequential R-R intervals in msec(i.e. heart periods). Heart period data were edited to remove movement artifact. Heart period data were quantified as : 1) mean heart period; 2) vagal tone. Vagal tone was quantitfied with a noninvasive measure developed by Porges(1985) in Mxedit software. To determine behavioral status, tools were developed by Scafidi et al(1990) were used. Collected data were analyzed with the SPSS program using paried t-test, ANOVA, and Pearson correlation. The result were as follow. 1. The results of the ANOVAs indicated that vagal tone were signifcantly lower during bathing than baseline and post-bathing. There were significant differences in heart period and heart rate levels across the bathing. But the mean oxygen saturations and respirations were no differences. Also, there were no significant differences on behavioral sign, motor activity, behavioral distress, weight changes, morbidity, and hospitalization period. 2. To evaluate the relation between vagal tone and subsequent parameters, the two groups (the high group had 19 subjects and low group had 21subjects) were divided by the mean baseline vagal tone. Vagal tone measured prior to bathing were significantly associated with respiration before bathing, vagal tone during bathing, and the magnitude of change in both vagal tone. But, other subsequent reactivities were no differences in two groups. 3. Correlations were also calculated between vagal tone and the subsequent physiological reactivities from baseline through after- bathing. Correlations were significant between baseline vagal tone and baseline heart rate, between baseline vagal tone and baseline heart period, between baseline vagal tone and oxygen saturation after bathing. In summary, the bathing in this study showed a stressful stimulus on premature infants through there was significance in the physiological parameters. In addition, our study represents the documentation that vagal tone reactivity in response to clearly defined external stimulation provides an index of infant's status.
