Purpose: Preterm infants frequently require red blood cell (RBC) transfusions in neonatal intensive care units (NICU). Storage RBCs undergo many changes during storage periods. We aimed to compare the hemoglobin (Hb) correction effect according to the period of RBC storage and investigate the factors influencing Hb correction. Methods: This retrospective study reviewed the medical records of 289 patients who received RBC transfusion more than once in the NICU of Kosin University Gospel Hospital between February 2006 and March 2016. The subjects were classified into two storage groups: short-term (${\leq}7days$, n=88) and long-term (>7 days, n=201), according to the period of RBC storage. We checked Hb levels by complete blood cell count tests conducted within 2 days before and 5 to 9 days after the first transfusion. We compared the Hb difference between the two groups and analyzed the factors influencing Hb correction. Results: Excluding the use of an invasive ventilator, there was no significant difference between the two groups in terms of clinical characteristics. There was no significant difference in the Hb correction effect between the two groups (P=0.537). Birth weight greater than 1,500 g, higher weight at transfusion, and larger volume of transfusion were significant prognostic factors affecting greater changes in Hb. In addition, surgery experience, higher Hb level at transfusion, and additional blood tests were found to be significantly associated with less changes in Hb. Conclusion: The RBC storage period did not affect the Hb correction effect. The Hb correction effect may be diminished in infants with lower birth weight and lower weight at transfusion under unstable clinical conditions.

Purpose: The purpose of this study was to examine the paternal stress and nursing support as perceived by fathers of high risk infants admitted to Neonatal Intensive Care Units (NICU). Methods: The study participants included 88 fathers of high risk infants in NICUs. Their parental stress and nursing support were measured using a self-report questionnaire. Results: The parental stress level of the fathers was 3.57 of a possible 5. Among the parental stress items, 'Relationship with infant and parental role' had the highest scores. The perceived nursing support level was a relatively high, 3.90 on a 5-point scale. The lowest score was for the item 'showed concern about my well-being.' The parental stress was lower in fathers with low income, higher in fathers in nuclear families and when the infants' condition was serious. Conclusion: The findings indicate that fathers of high risk infants experience intense parental stress. Thus when designing care to provide support for these fathers and their infants, it is necessary to encourage the fathers' engagement, provide information on how to respond to the baby, and include supportive care to the fathers.

목적 : 본 연구에서는 신생아중환자실 내 로타바이러스 감염의 발생 현황과 임상 양상을 분석하고 타 병원에서 전원된 신생아의 로타바이러스 감염이 신샹아 중환자실 내 로타바이러스 감염의 발생에 미치는 영향을 알아보고자 하였다. 방법 : 2001년 1월부터 2006년 12월까지 고려대학교 부속 안산병원 신생아중환자실에 입원한 환아 중 대변 검체에서 로타바이러스 감염을 진단받은 94명을 대상으로 의무 기록을 후향적으로 분석하였다. 로타바이러스 감염의 진단을 환아의 대변 검체를 이용한 로타바이러스 항원 검사에서 양성일 경우로 정의하였다. 통계학적으로는 SPSS 프로그램에서 Student's t-test, chi-square test와 time series analysis를 이용하였으며 유의수준 <0.05로 검증하였다. 결과 : 연구 기간 동안 신생아중환자실에 입원한 1,501명 중 94명(6.3%)이 로타바이러스 감염으로 진단되었으며 1,000 재원일수 당 4.9건이 발생하는 것으로 확인되었다. 연구 기간 중 타 병원에서 전원된 신샹아 223명 중 24명(10.8%)이 입원 시 시행한 검사에서 로타바이러스 감염으로 진단되었다. 로타바이러스 감염의 주된 증상은 황달의 악화 및 발생이 33례(35.1%)였고 설사를 포함한 붉은 변 24례(25.5%), 구토 15례(16.0%)를 보였으며 그 밖에 발열 9례(9.6%), 무호흡 5례(5.3%), 보챔 5례(5.3%), 경련( 5례(5.3%), 끙끙거림 4례(4.3%), 위 잔류량 증가 3례(3.2%) 등을 보였다. Stage II이상의 신샹아 괴사성 장염으로 진단된 환아는 3례(3.2%)이었다. 미숙아군(n=44)과 만삭아군(n=50)의 비교에서 황달의 악화 및 발생이 미숙아군에서 유의하게 많았으며 경련이 만삭아군에서, 신생아 괴사성 장염이 미숙아군에서 많이 발생하는 경향을 보였으나 통계적으로 유의하지 않았다. 타 병원에서 전원된 신생아의 입원 1개월 후 기존의 샌생아중환자실 입원 환아에서 로타바이러스 감염의 빈도가 증가하는 것을 확인할 수 있었다. l이러한 로타바이러스 감염은 2내지 4개월 후에 그 발생빈도가 감소하는 것도 확인할 수 있었다. 결론 : 신생아중환자실 내 로타바이러스 감염은 드물지 않으며 황달의 악화 및 발생, 무호흡, 경련 등의 비전형적 증상이 상대적으로 많았다. Stage II 이상의 신샹아 괴사성 장염도 3.3%에서 발생하였으며 로타바이러스 감염을 지닌 환아가 신생아중환자실에 전원됨으로써 신생아중환자실 내 감염의 급증이 일어날 수 있으므로 로타바이러스 감염에 대한 상시적인 검사와 엄격한 관리가 필요하리라 생각된다.

Purpose: This study was performed to develop a valid and reliable Korean Patient Classification System for Neonatal care nurses (KPCSN). Methods: The study was conducted in tertiary and general hospitals with 1~2 grade according to nursing fee differentiation policy for NICU (neonatal intensive care unit) nurse staffing. The reliability was evaluated for the classification of 218 patients by 10 nurse managers and 56 staff nurses working in NICUs from 10 hospitals. To verify construct validity, 208 patients were classified and compared for the type of stay, gestational age, birth weight, and current body weight. Nursing time was measured by nurses, nurse managers, and nurse aids. For the calculation of conversion index (total nursing time divided by the KPCSN score), 426 patients were classified using the KPCSN. Data were collected from September 5 to October 28, 2015, and analyzed using t-test, ANOVA, intraclass correlation coefficient, and non-hierarchial cluster analysis. Results: The final KPCSN consisted of 11 nursing categories, 71 nursing activities and 111 criteria. The reliability of the KPCSN was r=.83 (p<.001). The construct validity was established. The KPCSN score was classified into four groups; group $1:{\leq}57points$, group 2: 58~80 points, group 3: 81~108 points, and group $4:{\geq}109points$ in the KPSCN score. The conversion index was calculated as 7.45 minutes/classification score. Conclusion: The KPCSN can be utilized to measure specific and complex nursing demands for infants receiving care in the NICUs.

In effort to conduct comparative study on the caregiving environment of Neonatal Intensive Care Unit(NICU) in both U. S and Korea, this study was been conducted first in the U.S. Purpose : The purpose of this study is to identify the physical environment and direct caregiving practices to lowbirth weight infants in NICU in the US. It also aims to examine the NICU outcome status and behavioral reponses of lowbirth weight infants. Methods : A study design using descriptive and inferential statistics was been conducted through an observational, field method. A sample of 15 preform infants admitted to NICU were recruited for the study. The subjects were those with birth weight between 1,000 gm to 1,500 gm, born at the gestation period of 27 to 33 weeks, and without any chromosomal or other genetic anomalies, major congenital infections, or maternal illness. Thirty minutes observation(three times of ten minutes of continuous observation)of the infant's behavior and physiological status, and an four-hour observation of the physical environment and direct care giving procedures were been conducted on the 3rd and 10th day after birth, and on the day of discharge from the NICU or at 34weeks postconception. The data to be collected were in four areas : the demograghic characteristics of the infants, the physical environment and care giving procedures, the frequency of the infant's designated behavior and physiological response, and NICU outcome variables. A descriptive analysis and Kruskal-Wallis, Pearson r were been applied according to variable characteristics. Results : 1. Mother's mean age was 29.47. The sample consisted of 6 males and 9 females. Mean gestational ages were 29.17 weeks. Mean birth weight was 1236.33g. Mean Apgar scores at one minute were 6.6, and 7.8 at five minutes. 2. The location for the incubator was in the distance from the light, X-ray screens and nursing station, in proximity to side-lamp, telephone and faucet on the third day after birth. The location for the incubator was in the distance from the light and radio on the tenth day and in proximity to nursing station on the day of dischage from the NICU or at 34weeks postconception. 3. Nesting was the most applying aids to the infants. And foot roll, shielding and plastic frame were frequently using by nurses for facilitating well modulated restful posture. 4. There were statistically significant changes in the patterns of physical environment included locating the infant's incubator and bedding, specific aids to self regulation on the 3rd and 10th day after birth, and on the day of discharge from the NICU or at 34weeks postconception. 5. Statistically significant changes were not appeared in the patterns of direct caregiving procedure to the infants included stress inducing or reducing manipulations on the 3rd and 10th day after birth, and on the day of discharge from the NICU or at 34weeks postconception. 6. The stress response of the infants in NICU were significantly reduced as the infants grow older. 7. There were not statistically significant correlation between the physical envronment and the stress responses of the infants in NICU. 8. There were statistically significant correlation between the direct caregiving procedure to the infants and the stress response of the infants in NICU in the second and third observation on the day three. 9. Average weight gain per day from birth to discharge was 38.73g, number of days in the hospital was 42.60, number of days before bottle feeding was 3.6. Postconception age starting bottle feed ing was 31/sup +5/ weeks. Number of days on mechanical ventilator was average 7.64, 11.42 was an average number of days of oxygen need. Conclusion : It, thus, appears that to minimize the sensorymotor stimulation for the low birthweight preterm infant in NICU, manipulation of care giving practices to the babies whatever the stress inducing or reducing procedures, have to be limited in the immediate early stage after birth. And it needed to be reexamine to identify the appropriate and specific physical environment and the patterns of direct caregiving to the low birthweight preform infant as the infants grow older in NICU.

Purpose: To investigate the degree and sources of stress which fathers of infants in NICU experience. Method: Eighty-five fathers of NICU infants at 5 university hospitals in Seoul volunteered to complete the Parental Stressor Scale for NICU (PSS: NICU) from September 1, to October 15, 2002. Result: Total perceived stress was 3.50±0.76. The highest score were in Parental Role Alteration (3.76±0.83) and Appearance and Behavior (3.65±1.04). The total perceived stress score (PSS), correlated significantly with method (t=3.50, p=.01), and route (F=5.30, p=.00) of feeding. Light & Sound correlated significantly with birth weight (F=3.39, p=.02), medical diagnosis(F=2.30, p=.03), plan of operation(t=2.50, p=.01), operation (t=3.80, p=.02), method (F=4.90, p=.003), and route (F=4.70, p=.00) of feeding. Infant Appearance and Behavior correlated significantly with birth weight (F=5.12, p=.01), plan of operation (t=2.50, p=.01), method (F=3.50, p=.01), and route (F=7.80, p=.00) of feeding. Parental Role Alteration correlated significantly with care of incubator (t=-.68, p=.03), method of feeding (F=2.80, p=.04) and education level of father (F=3.00, p=.05). Conclusion: Father with NICU infants were concerned mostly with parental role alteration and infant appearance. Nursing intervention should include fathers of NICU infants.

Purpose: To investigate factors that may affect the method of feeding among preterm infants at 4 weeks after discharge. Methods: This study included 222 mother-infant dyads born before a gestational age of 37 weeks. The feeding method and general medical characteristics of the participants were assessed at 4 weeks after discharge using a structured questionnaire. Multinomial logistic regression analysis was used to examine which factors were associated with breastfeeding at home. Results: Of the 222 infants who qualified for the study, 71 (32.9%) continued to receive breastmilk at 4 weeks post-discharge. Multinomial logistic regression analysis showed that breastfeeding at 4 weeks post-discharge was associated with higher breastfeeding self-efficacy, vaginal delivery (experience), direct breastfeeding in the neonatal intensive care unit (NICU), gestational age between 30 and 34 weeks, and breastmilk consumption in the NICU. The following factors were associated with mixed feeding at 4 weeks post-discharge: being employed, having higher breastfeeding self-efficacy, and direct breastfeeding in the NICU. Conclusion: NICU nurses should provide opportunities for direct breastfeeding during hospitalization and support breastfeeding to enhance breastfeeding self-efficacy. These factors may help to ensure the continuation of breastfeeding after discharge. Moreover, factors that affect breastfeeding should be considered when providing interventions.

Purpose: Maintaining body temperature is a key vital function of human beings, but little is known about how body temperature of highrisk infants is sustained during early life after birth. The aim of this study was to describe hypothermia in high-risk infants during their first week of life and examine demographic, environmental, and clinical attributors of hypothermia. Methods: A retrospective longitudinal study was done from January 1, 2013 to December 31, 2015. Medical records of 570 high-risk infants hospitalized at Neonatal Intensive Care Units (NICU) of a university affiliated hospital were examined. Body temperature and related factors were assessed for seven days after birth. Results: A total of 336 events of hypothermia (212 mild and 124 moderate) occurred in 280 neonates (49.1%) and most events (84.5%) occurred within 24 hours after birth. Logistic regression analysis revealed that phototherapy (aOR=0.28, 95% CI=0.10-0.78), Apgar score at 5 minute (aOR=2.20, 95% CI=1.17-4.12), and intra-uterine growth retardation or small for gestational age (aOR=3.58, 95% CI=1.69-7.58) were statistically significant contributors to hypothermia. Conclusion: Findings indicate that high-risk infants are at risk for hypothermia even when in the NICU. More advanced nursing interventions are necessary to prevent hypothermia of high-risk infants.
