Purpose: This study was done to develop a video discharge education program focusing on mother-infant interaction to facilitate the development of maternal role confidence for mothers of premature infants. Methods: The process of the program was based on the Network-based Instructional System Design suggested by Jung (1999). For the content of the program, needs and concerns of mothers of premature infants found on web sites and existing literature were analyzed. Based on this content, the scenario and the video were developed. Nurses and mothers of premature infants participated in the process of testing the content validity, scenario development, and evaluation of final video production. The final video has two parts and lasts 21 minutes. The first part focuses on mother-premature infant interaction and the second part focuses on health management of infants. Results: Eleven mothers of premature infants participated in the evaluation of the appropriateness of the video as a teaching method and for educational content. They reported that the content on mother-infant interaction, maternal sensitivity, and maternal role confidence was especially beneficial. Conclusion: The findings indicate that video program is effective for education on maternal-premature infant interaction and the use of video in practical settings is strongly recommended.

Purpose : The purpose of this study was to investigate the effect of sensorimotor stimulation on the development of infant with low birth weight premature. Methods : Ten infants with low birth weight premature and ten normal infants participated in this study. We carried out test TIMP(Test of Infants Motor Performance) according pre intervention, post 3 weeks, PCA 40 week and normal infants. The intervention of sensorimotor stimulation applied to infants with low birth weight premature four times a week and fifteen minutes a once time. There was no intervention for normal infants. The collected dada were analyzed by ANOVA using by SPSS/PC 17.0 ver. program. Results : There was significant difference among three differential test period to improved developmental value in infants with low birth weight premature. According over time, numbers of observed items presented significant difference among test period, and elicited total score and total raw score was significant value(p=.00). There was no significant value that means sensorimotor stimulation affected on development of infants with low birth weight premature. Conclusions : In conclusion, sensorimotor stimulation had affects on the development of infants with low birth weight premature.

Recently, the survival of the high-risk population of preterm infants has steadily improved, and the severity of prematurity is a growing threat of gestational-age-related fatal conditions. Posthemorrhagic hydrocephalus (PHH) is the most common but serious neurological complication in premature infants, which can have life-threatening consequences during the acute phase in the neonatal period and life-long psychomotor and cognitive sequelae in their later life. Although neonatologists, pediatric neurologists, and pediatric neurosurgeons have investigated a diversified strategy for several decades, a consensus on the best management of PHH in premature infants still must be reached. Several approaches have tried to reduce the incidence of intraventricular hemorrhage (IVH) and mitigate the effect of IVH-related hydrocephalus. This paper reviews and discusses the clinical feature of PHH in premature infants, general/nonsurgical management of prematurity for IVH prevention, and posthemorrhagic management, and how and when to intervene.

Purpose: This study investigated predictive factors for severe neonatal thrombocytopenia, which greatly increases the need for intensive care and is associated with a high mortality rate in premature infants. Factors adopted for prompt identification of at-risk newborns include blood test results and birth history. This study analyzed the relationship between the presence of severe neonatal thrombocytopenia and the mortality rate. The causes of thrombocytopenia in premature infants were also examined. Methods: This retrospective study evaluated 625 premature infants admitted to the neonatal intensive care unit (NICU) at Chung-Ang University Medical Center. The neonates were classified into 3 groups according to the severity of thrombocytopenia: mild ($100{\times}10^9/L{\leq}platelet<150{\times}10^9/L$), moderate ($50{\times}10^9/L{\leq}platelet<100{\times}10^9/L$), or severe (platelet<$50{\times}10^9/L$). Analysis of blood samples obtained at the onset of thrombocytopenia included platelet count, white blood cell (WBC) count, hemoglobin level, hematocrit level, absolute neutrophil count, and high-sensitivity C-reactive protein level. Results: Of the 625 premature infants admitted to our NICU, 214 were detected with thrombocytopenia. The mortality rate in thrombocytopenic neonates was 18.2% (39/214), whereas a mortality rate of only 1.0% was observed in non-thrombocytopenic neonates. The major causes of thrombocytopenia were perinatal insufficiency and sepsis in premature infants. Severe thrombocytopenia was noted more frequently in premature infants with higher WBC counts and in those with a younger gestational age. Conclusion: Platelet count, WBC count, and gestational age are reliable predictors for severe neonatal thrombocytopenia. The major causes of thrombocytopenia were perinatal insufficiency and sepsis in premature infants.

Pulmonary surfactant (PS) therapy in premature infants has a remarkable impact on improving survival and outcomes in neonatal respiratory distress syndrome (RDS). Early PS therapy involves instillation of PS upon delivery of very premature infants or if there is evidence of RDS, such as an increased requirement of oxygen 2 hours after birth, especially in infants <30 weeks gestation. Early PS treatment in very premature infants results in a significant reduction in the severity of RDS, mortality, and incidence of pneumothorax, pulmonary interstitial emphysema, and bronchopulmonary dysplasia in comparison with late PS treatment. According to European and American consensus guidelines on the management of neonatal RDS, early PS instillation should be considered for infants <30 weeks gestation, infants with a birth weight <1,250 g, or if the mother has not received antepartum corticosteroids. We suggest that the Korean health insurance policy on RDS be modified so that PS can be used for better clinical outcomes of very premature infants.

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:　The purpose of this study is to identify how regular stimulation affects apnea of a premature infant. Method: This study was used a within-subjects design with repeated measure using GEE (General Estimating Equation) and had been conducted from July 1, 2003 to March 12, 2004. The subjects consisted of 11 apneic premature infants who had showed apnea more than twice for 12 hours. A regularly vibrating test lung was provided to the subjects to find how regular stimulation affects apnea. Result: From the result of regular stimulation for apneic premature infants, both the lowest SaO2 and the lowest heart rate at experimental period were found to be increased significantly. However, the decreased frequency of the apnea cases was not statistically effective. Conclusion: These findings indicate that regular stimulation for apneic premature infants could be effective on increasing both SaO2 and heart rate. Therefore, we suggest regular stimulation to be used clinically to heal apnea of premature infants.

Purposes: The purposes of this study are to describe the health problems experienced by VLBW premature infants and their health care services utilization during the first year of life Method: Eighteen mothers of VLBW premature infants completed a survey questionnaire, asking socioeconomic/demographic information, health/developmental problems experienced by their infants, and their use of health care services. Results: Of the 18 infants, 78% experienced respiratory problems such as cold/running nose and wheezing during the first year and 33% experienced gastrointestinal problems such as vomiting, diarrhea and constipation. Twelve (67%) infants visited the emergency department at least one time and 10 infants (56%) were hospitalized at least once during their first year of age. Interestingly, infants without chronic lung disease visited the emergency department more than infants without chronic lung disease (p=.213). Infants living in non-disadvantaged neighborhoods were hospitalized more than infants living in disadvantaged neighborhoods (p=.000). Conclusions: Health care providers should initiate educating mothers, particularly those living in disadvantaged neighborhoods, about post-NICU discharge health care needs of their VLBW premature infants while their infants were still in the NICU so that unnecessary visits to the emergency department and rehospitalizations can be possibly prevented.

Purpose: The purpose of this study was to compare the result of one-way ANOVA with that of cross-correlation time series analysis in order to evaluate physiologic responses of premature infants to human voices. Methods: Four premature infants born prior to 32 weeks gestational age were included in the study. The Gould 4000TA Recording System recorded the preterm infant's heart and respiratory rate while they were listening to a pre-recorded voice recording. Each infant listened to both male and female voices (1 min each) at each testing session. Results: The results of both one-wayANOVA and cross-correlation time series analysis using heart and respiratory rate data were not consistent in some of premature infants. A cross-correlation time series analysis revealed that the responses of premature infant to vocal stimulation occurred at a varying number of seconds after the stimulus was presented and lasted for over 20-30 sec. Conclusion: The results indicate that a time series analysis can provide more detailed information on the rapidly changing physiologic status of premature infant to the auditory stimulus. In addition, the results provide an insight into an auditory responsitivity of premature infants to a naturally occurring sound, the human voice, in the neonatal intensive care unit.

Purpose: This study was conducted to monitor the development of Korean premature infant at six-month age and to explore factors related to developmental status of the premature infants. Methods: Participants were 58 premature infants whose corrected age was six-months old and their mothers. The developmental states of infants were followed-up with the Korean Prescreening Developmental Questionnaire (KPDQ-II). Clinical characteristics of the infants were identified from the medical records. Other characteristics including Edinburgh Postnatal Depression Scale, husband's support, social support, and mother-infant attachment were assessed using self-report questionnaires from the mothers. Results: Forty three percent of the infants were in the group of questionable status of development on the KPDQ-II. There were significant differences between the premature infants with normal developmental status and those with questionable developmental status depending on gender ($x^2$=5.03, p=.034), gestational age (t=2.59, p=.012), hospital stay (p=.013), revised Neurobiologic Risk Score (p=.005) and mother-infant attachment score (t=2.12, p=.040). Conclusion: Mother-infant attachment, as well as physiological state of premature infants, is an important variable in early development. Therefore, early monitoring for the development has to be done for physiologically vulnerable premature groups. Also, providing proper nursing support to improve maternal attachment needs to be considered.
