Over a 3 year period, 10 premature infants with less than 37 weeks of gestational age underwent ductal ligation for patent ductus arteriosus. No patient died during operations which were done at a mean age of 30 days. One late death at 2 months after operation was not directly attributed to operative procedure. Follow-ups were done in 9 survived patients from 2 to 26 months. Results suggest that surgical ligation is a feasible and effective method for treating symptomatic premature infants with patent ductus arteriosus.

Purpose: This study was aimed to evaluate the effects of Labor Support Behaviors (LSB) one-to-one application and partner's delivery participation on the delivery satisfaction and delivery results among mothers who delivered premature birth and low birth weight infant. Methods: The data were collected from 30 mothers in the experimental group and 27 in the control group from April 23, 2009 to April 22, 2010. The collected data were analyzed using percentage, mean, standard deviation, $x^2-test$ (Fisher's exact test) and t-test with SPSS. Results: The satisfaction levels of the experimental group and the control group women were $3.73{\pm}0.43$ and $3.72{\pm}0.34$ as mean values, respectively, showing not statistically different (t=0.07, p=.945). None showed less than 7 point of Apgar score at 1 minute in the experimental group while 5 out of 27 did (18.5%) in the control group, which was statistically meaningful. Also, the emergent cesarian section cases were 3 out of 33 (9.1%) in the experimental group and 5 out of 32 (15.6%) in the control group, demonstrating lower emergency cesarian section rate in the experimental group than the control group, but showing not statistically different ($x^2=0.643$, p=.475). Conclusion: The results of this study show that LSB one-to-one application and partner's participation has affirmative effects on 1 minute Apgar scores of newborns.

Purpose: The purpose of this study was to identify the noise level and frequency experienced by premature infants receiving incubator care in the neonatal intensive care unit (NICU). Methods: The participants were 20 premature infants receiving incubator care in the NICU of a university hospital in Daejeon Metropolitan city. The noise level was measured using a professional sound-level meter (ET-958, FLUS, Shenzhen, China) based on a noise classification table developed by the author. The data were analyzed with descriptive statistics, the t-test, analysis of variance, and Pearson correlation coefficients using SPSS for Windows version 22.0. Results: The average noise level experienced by premature infants receiving incubator care in the NICU was 51.25 dB (range: 45.0~81.7 dB). The frequency of noises was highest for factors related to nursing activities (40.3%), followed by human factors (29.1%), machine alarm sounds (20.1%), incubator operation (6.6%), and internal environmental factors (3.9%). Conclusion: According to the above results, the noise level experienced by premature infants receiving incubator care in the NICU exceeded the recommendations of the American Academy of Pediatrics. Therefore, it is necessary to develop an interventional program to reduce noise in the NICU, and to conduct follow-up studies to verify its effectiveness.

Purpose: The research was conducted to investigate the experience of maternal role attainment of mothers of premature infants admitted in NICU and to conceptualize the phenomena. Method: The grounded theory method was utilized for data collection and analysis. 8 mothers of premature infants were selected and in-depth interview was performed. Paradigm model was utilized for data analysis and presentation. Result: The central category was 'unstable maternal identity'. The properties of the core phenomena was 'ambivalent feeling to baby' 'negative emotion' 'commitment to baby'. The loss of control due to premature delivery was the causal condition. contextual condition was the 'perceived threats' due to severity of the premature infant and uncerainty of the baby's life. The mother's health status, economic status, and familial and social support was recognized as intervening conditions during the process of maternal role attainment. The strategic action/interactions were emotion-focused coping, reappraisal of the situation, problem-focused coping, and information seeking. The consequence was the maternal role attainment with competence and expectation. Conclusion: The process of maternal role attainment was affected by threats due to severity of the baby and intervening factors and interaction strategy. Further research is recommended to develop adequate intervention method during the process of maternal role attainment.

Purpose: This study was done to investigate the effects of a massage program on the growth of premature infants and on the mothers' confidence and satisfaction in the mothering role. Methods: The participants were 29 mothers of premature infants hospitalized in a neonatal intensive care unit at CNU Hospital (14 in the massage program group and 15 in control group). Massage was done for 10-15 minutes, 2-3 times a day for 4 weeks. The data were using the SAS PC+ program. Result: Significant differences were found in the ratios of weight gain (Z=2.24, p=.013), grow in length (Z=2.50, p=.006) and increase in head circumference (Z=1.91, p=.028) between the massage program group and the control group. Confidence in the mothering role was significantly higher for mothers in the massage program group compared to those in the control group (Z=2.69, p=.004), but there was no significant difference in satisfaction with the mothering role between the two groups (Z=.88, p=.191). Conclusion: These results suggest that the massage program enhances growth of premature infants as well as enhancing the mother's confidence in her role as mother. Therefore, the massage program for premature infants can be use as an effective nursing intervention.

Purpose: This study aimed to examine the health concerns of parents regarding their premature infants and to identify changes in these concerns during perinatal period and after discharge. Methods: This was a retrospective study performed at a single tertiary center that enrolled 119 premature infants who were discharged from the neonatal intensive care unit (NICU) and visited the outpatient pediatrics department between December 2018 and October 2021. Data on the concerns of 176 parents regarding enrolled premature infants' health from before birth to 1 week after NICU discharge were obtained from outpatient records. The t test and with the chi-squared test were used to analyze the data for this study. Results: The consistently greatest focus of parents' health concerns was the respiratory system. The second focus of parents' health concerns before discharge was the central nervous system. However, during the first week after NICU discharge, the gastrointestinal system was the second-most frequent focus of parents' health concerns among parents of infants without diseases related to prematurity and infants with older gestational ages. Conclusion: The results of this study offer insights into the health concerns among parents of premature infants. Parental health concerns about premature infants vary over time, from before birth to post-discharge, necessitating supportive interventions to enhance parental understanding of their child's health status.

Purpose : This study aimed to evaluate the usefulness of Korean Infant Development Screening Test in predicting delayed development in premature infants. Methods : A total of 74 children with histories of prematurity, who visited the pediatric neurology clinic of Korean University Ansan Hospital from August, 2002 to July, 2004, were examined, using the Korean Infant Development Screening Test. They were divided into two groups; a normal group and a patient(neurologically compromised) group. Results : At 7 months of conceptional age, the normal and patient groups differed significantly in the fine motor, cognitive-adaptive sections. At 12 months of conceptional age both group, differed significantly in the gross motor, fine motor, personal-social, language and cognitive-adaptive sections. At 18-24 months, the group, differed significantly in gross motor, fine motor, personal-social, language and cognitive-adaptive sections. Conclusion : The Korean Developmental Screening Test was useful in predicting developmental delay in premature infants.

Cronobacter species have been associated with disease outbreaks and sporadic infections, particularly in premature and immunocompromised infants. Cronobacter species can cause foodborne infections such as neonatal meningitis, septicaemia and necrotising enterocolitis. Accordingly, there is an urgent need to control and monitor the Cronobacter species in food, especially in powdered infant formula (PIF) and other baby foods. Therefore, in this review, the isolation and prevalence of Cronobacter species in infant food including PIF and the recent advance of detection methods are discussed for the better understanding on the current research status of Cronobacter species.

Cytomegalovirus (CMV) is one of the most commonly encountered viral pathogens in newborn infants and is found in 0.3-2.4% of all live births. It has been demonstrated that 40-96% of seropositive mothers shed the virus via their breast milk. Breast milk containing CMV can cause almost one-third of CMV infections occurring in infants. A case of postnatal CMV infection in an extremely premature infant (gestational age $24^{+5}$ weeks, birth weight 750 g) transmitted via breast milk is presented. For neonatal intensive care unit (NICU) management of severe thrombocytopenia, anemia, and sepsis syndrome, the infant received repeated transfusions of platelets; intravenous (IV) immunoglobulins; and gamma- irradiated, filtrated packed red cells and was fed her mother's breast milk since the second week of life. CMV infection was diagnosed with positive CMV immunoglobulin M (IgM) and positive urine CMV culture at the second month of life. Considering the negative CMV IgM and urine CMV culture at birth, postnatally-acquired CMV infection was suspected and confirmed with completely identical nucleotide sequence alignments of the infantile blood isolate and the maternal breast milk isolate. To our knowledge, this is the first case of proven postnatal CMV infection transmitted via breast milk in an extremely premature infant in Korea.

Prematurity is the main cause for respiratory distress syndrome (RDS) in neonates. The goal in the treatment of RDS is to maintain respiration with adequate oxygenation. ETS needs to be performed to remove lung secretions in the ventilated premature infants with RDS. Oxygen saturation(SpO$_2$) and heart rate(HR) were compared in 22 premature infants with RDS using two types of ETS : open ETS versus close ETS. The results showed there was no significant difference in the SpO$_2$ and HR responses between open ETS and close ETS. The SpO$_2$ and HR returned to the baseline within 1 minute after suctioning. But in some case, there was a significantly greater incidence in the decrease of SpO$_2$ below 90% occured in the open ETS than in the close ETS. It implies that closed ETS may be beneficial to the premature infants who tend to develop desaturation easily.
