OBJECTIVES: OCT(Point-of-Care Test), often translated as "Bedside laboratory", is a testing method used in most developed countries to conduct medical research. It is known to extract rapid results that can be applied in the intensive care unit. This study was conducted to investigate the correlation of the i-STAT(TM) POCT analyzer with the traditional test in the neonatal intensive care units. METHODS: 60 babies(birth weight > or =1.0kg) who were admitted to neonatal intensive care unit from June, 2000 to June, 2001 at Asan Medical Center requiring blood samples for the testing of arterial blood gas analysis(ABGA), electrolytes, hemoglobin(Hb), hematocrit(Hct), were included in the study. Blood samples were taken simultaneously to be tested by the traditional laboratory method and by i-STAT(TM) (i-STAT Co. USA) POCT analyzer. The data used for comparison analyzation included pH, pCO2, pO2, HCO3, Na, K, Hb, and Hct. RESULTS: 245 measurements of ABGA and 195 measurements of Na, K, Hb, Hct from 60 babies were used for comparison. Good correlation of data was found between i-STAT(TM) POCT analyzer and traditional laboratory method obtained from the central laboratory(correlation coefficient: pH 0.954, pCO2 0.944, pO2 0.941, HCO3 0.880, Na 0.713, K 0.860, Hb 0.864, Hct 0.880). CONCLUSION: This study showed that i-STAT(TM) POCT analyzer provided accurate analytic results when compared with traditional laboratory method used in the neonatal intensive care units.

2.Neonatal Nurse's Professional Self-concept and Behavior to Protect Patient Privacy.
Journal of Korean Academy of Nursing Administration 2012;18(4):424-433
PURPOSE: With the rapid increase in information technology in the medical environment, protection of patient's privacy is a crucial issue to hospital nurses. The purpose of this study was to determine neonatal nurses' perception and performance of behavior to protect patient privacy, and professional self-concept, and to investigate the relationships among these variables. METHODS: The participants in this descriptive correlation study were 182 nurses in nursery and neonatal intensive care units using EMR or OCS in November, 2011. RESULTS: Perception and performance averaged 4.61 and 4.04 (out of 5) respectively, and the average score for professional self-concept was 2.73 (out of 4). There was a significant difference between perception and performance. The performance of behaviour to protect patient privacy had a positive correlation with perception and professional self-concept. Multiple regression analysis showed that the key determinants of performance were recognition of necessity of patient privacy education, professional self-concept and perception, and these explained 36% of the total variance of performance. CONCLUSION: Study results indicate a need to establish policy to protect privacy of neonates and their families, and to develop educational programs to enhance neonatal nurses' perception and performance.

3.The Effects of Massage on Stress Hormone in Premature Infants.
Korean Journal of Child Health Nursing 2005;11(1):125-131
PURPOSE: This study was done to evaluate the effects of massage on the level of stress hormone in the urine in preterm infants. METHOD: The design was a nonequivalent control group pretest-posttest design quasi experimental study. Fifty-eight preterm infants were assigned to the experimental(31) or control group(27). The data were collected from March 2002 to August 2003. The massage stimulation was provided to infants in the experimental group for 15-minutes twice a day for 10 days. On day 1 and day 10 of the study, a 24 hour-urine sample was collected for norepinephrine, epinephrine, and cortisol assays. In data analysis, SPSSWIN 10.0 program was utilized for descriptive statistics, ANOVA and t-test. RESULTS: General characteristics of the two groups showed no significant differences, thus the two groups were found to be homogenous. The 24 hour-urine cortisol of the massage group (t=4.61, p=.000) was significantly reduced compared to the control group after 10 days. CONCLUSIONS: The results suggest that the massage stimulation can be used to reduce 24 hour-urine cortisol in preterm infants. Therefore, massage provided in the incubator is recommended for reduction of stress in preterm infants who are hospitalized in neonatal intensive care units.

BACKGROUNDTo investigate the incidence and risk factors of retinopathy of prematurity (ROP) in two Neonatal Intensive Care Units in North and South of China, respectively.
METHODSWe studied data concerning 472 infants with gestational age (GA) ≤ 34 weeks or birth weight (BW) ≤ 2000 g who were admitted to the Zhujiang Hospital of Southern Medical University and the Fourth Hospital of Shijiazhuang between January 1, 2011 and December 31, 2011. Clinical information about perinatal neonates was collected and was confirmed by reviewing medical charts. The incidence and severity of ROP were assessed in the screened population. Main outcome measures are the incidence and severity of ROP. The relationship of clinical risk factors and the development of ROP were analyzed.
RESULTSThe overall incidence of ROP was 12.7%, and the overall incidence of type 1 ROP was 2.3%; 9.4% of infants in Zhujiang Hospital had ROP compared to 15.0% infants in the Fourth Hospital of Shijiazhuang developed ROP, and the difference is statistically significant. ROP was significantly associated with GA (odds ratio [OR]: 0.77 [0.62-0.95], P = 0.015), BW (OR: 0.998 [0.996-0.999], P = 0.008), maternal supplemental oxygen administration before and during delivery (OR: 4.27 [1.21-15.10], P = 0.024) and preeclampsia (OR: 6.07 [1.73-21.36] P = 0.005). The risk factors for ROP are different in two hospitals. In Zhujiang Hospital, BW is the independent risk factors for ROP while GA, BW and preeclampsia in the Fourth Hospital in Shijiazhuang Conclusions: Retinopathy of prematurity incidence is different based on area. Incidence of ROP is still high in China. More efforts need to prevent ROP.

OBJECTIVE:
To study the results of TEOAE and AABR hearing screening and follow-up in NICU.
METHOD:
Total 574 cases in NICU were included in this study, all cases received both TEOAE and AABR hearing screening while admission and rescreening when one-month-old. The cases that were abnormal on either test in rescreening were asked to return for diagnostic tests at 3 moths old. The patients who didn't return as required in 3 months were surveyed by call and analyzed.
RESULT:
Among 574 cases, 472 cases passed both TEOAE and AABR hearing screening while admission. While 102 cases had abnormal test results in either screening test. Thirty-three cases returned for follow-up, 13 of which passed rescreening test one month after discharge, the other 20 cases had ABR diagnostic tests after 3 months. Among them, 8 cases had normal hearing, 12 cases had various degree of hearing loss. Sixty-nine cases lost follow-up. The reason of lost follow-up was as follows, parents changed phone number/contact information, parents didn't understand the screening results, parents believe that their children having no need for further testing; parents had retest in other hospitals, parents didn't pay attention to hearing loss because of other severe complicated comorbidities.
CONCLUSION
The passing rate (normal) of TEOAE and AABR hearing screening in NICU was 82.2%, non- passing rate wass 17.8%, and the prevalence of hearing loss was high in those followed cases. Hyperbilirubinemia was the main risk factors of hearing loss in our NICU patients. We reviewed the reason for high rate (67.6%) of losing follow-up.

Journal of Korean Academy of Nursing 2006;36(5):691-700
PURPOSE: This study was done to analyze variations in unit staffing and recommend policies to improve nursing staffing levels in intensive care units (ICUs). METHOD: A cross-sectional study design was used, employing survey data from the Health Insurance Review Agency conducted from June-July, 2003. Unitstaffing was measured using two indicators; bed-to-nurse (B/N) ratio (number of beds per nurse), and patient-to-nurse (P/N)ratio (number of average daily patients per nurse). Staffing levels were compared according to hospital and ICU characteristics. RESULT: A total of 414 institutions were operating 569 adult and 86 neonatal ICUs. Tertiary hospitals (n=42) had the lowest mean B/N (0.82) and P/N (0.76) ratios in adult ICUs, followed by general hospitals (B/N: 1.34, P/N: 0.97). Those ratios indicated that a nurse took care of 3 to 5 patients per shift. Neonatal ICUs had worse staffing and had greater variations in staffing ratios than adult ICUs. About 17% of adult and 26% of neonatal ICUs were staffed only by adjunct nurses who had responsibility for a general ward as well as the ICU. CONCLUSION: Stratification of nurse staffing levels and differentiation of ICU utilization fees based on staffing grades are recommended as a policy tool to improve nurse staffing in ICUs.

PURPOSE: The aims of this study were to determine the factors affecting the outcome of patent ductus arteriosus ligation in very low birth weight infants (VLBWI) and demonstrate the safety of PDA ligation in VLBWI performed in the neonatal intensive care unit (NICU). MATERIALS AND METHODS: From October 1994 to July 2006, medical records of 94 VLBWI weighing < 1,500g who underwent PDA ligation in the NICU of Samsung Medical Center were reviewed retrospectively. Factors affecting the final outcome of PDA ligation were evaluated by dividing the infants into 3 groups according to mortality and major morbidities as follows: mortality group (Mo), major morbidity group (Mb), and no major morbidity group (NM). RESULTS: In the Mo group, birth weight was significantly lower and the preoperative mean FiO(2) and mean dopamine dose were significantly higher than those in the other 2 groups. There was no significant difference in gestational age, incidence of RDS, number of courses of indomethacin, surgery-related factors, including weight and age at surgery, perioperative vital signs, and complications after surgery between the 3 groups. During surgery in the NICU, there were no significant hemodynamic instability or serious acute complications. CONCLUSION: The factors affecting the outcome of surgery in VLBWI are not the factors related to surgery but the preoperative conditions related to the underlying prematurity. PDA ligation of VLBWI performed in the NICU is safe without serious complications.

BACKGROUNDGlobally, the proportion of child deaths that occur in the neonatal period remains a high level of 37-41%. Differences of cause in neonate death exist in different regions as well as in different economic development countries. The specific aim of this study was to investigate the causes, characteristics, and differences of death in neonates during hospitalization in the tertiary Neonatal Intensive Care Unit (NICU) of China.
METHODSAll the dead neonates admitted to 26 NICUs were included between January l, 2011, and December 31, 2011. All the data were collected retrospectively from clinical records by a designed questionnaire. Data collected from each NICU were delivered to the leading institution where the results were analyzed.
RESULTSA total of 744 newborns died during the 1-year survey, accounting for 1.2% of all the neonates admitted to 26 NICUs and 37.6% of all the deaths in children under 5 years of age in these hospitals. Preterm neonate death accounted for 59.3% of all the death. The leading causes of death in preterm and term infants were pulmonary disease and infection, respectively. In early neonate period, pulmonary diseases (56.5%) occupied the largest proportion of preterm deaths while infection (27%) and neurologic diseases (22%) were the two main causes of term deaths. In late neonate period, infection was the leading cause of both preterm and term neonate deaths. About two-thirds of neonate death occurred after medical care withdrawal. Of the cases who might survive if receiving continuing treatment, parents' concern about the long-term outcomes was the main reason of medical care withdrawal.
CONCLUSIONSNeonate death still accounts for a high proportion of all the deaths in children under 5 years of age. Our study showed the majority of neonate death occurred in preterm infants. Cause of death varied with the age of death and gestational age. Accurate and prompt evaluation of the long-term outcomes should be carried out to guide the critical decision.

9.The Effects of Auditory and Vestibular Stimulation on Stress Hormones in Preterm Infants.
Journal of Korean Academy of Fundamental Nursing 2004;11(2):203-212
PURPOSE: This study was done to determine whether providing auditory and vestibular stimulation to preterm infants would have an effect on stress hormones. METHODS: The design was a nonequivalent control group pretest-posttest design in a quasi-experimental study. Seventy-nine preterm infants were assigned either one of two experimental groups or to a control group: 27 in the auditory stimulation group, 25 in the vestibular stimulation group and 27 in the control group. The criteria for inclusion in this study were 1) gestational age of less than 37 weeks, 2) birth weight of less than 2,500g, 3) the absence of congenital anomalies or specific diseases, 4) recovering physiological weight loss, and 5) weaned from ventilatory assistance or oxygen. The data were collected from March 2002 to May 2003. The auditory stimulation, a music audiotape, was provided 20 minutes twice a day for 10 days and the vestibular stimulation, an infant waterbed, was provided for 10 days. On day 1 and day 10 of the study, 24 hour urine sample was collected for norepinephrine, epinephrine, and cortisol assays. In the data analysis, SPSSWIN 10.0 program was utilized for descriptive statistics, ANOVA and t-test. RESULTS: General characteristics of the three groups showed no significant differences, thus three groups were found to be homogenous. The 24 hour urine cortisol for the auditory (t=3.489, p=.001) and for the vestibular (t=2.638, p=.013) stimulation group were significantly reduced compared to the control group after 10 days. CONCLUSION: The results suggest that auditory and vestibular stimulation can be used to reduce 24 hour urine cortisol in preterm infants. Therefore, music audiotapes and waterbeds provided in incubator are be recommended for reduction of the stress in preterm infants who are hospitalized in neonatal intensive care units.

BACKGROUNDMany studies have shown a relationship between birth weight discordance and adverse perinatal outcomes. This study aimed to investigate the perinatal risk factors and neonatal complications of discordant twins who are admitted to the neonatal intensive care unit.
METHODSA total of 87 sets of twins were enrolled in this retrospective study, of which 22 sets were discordant twins and 65 sets were concordant twins. Binary Logistic regression analysis was used to identify the risk factors associated with the occurrence of discordant twins. The common neonatal complications of discordant twins were also investigated.
RESULTSMultivariate analysis showed that the use of assisted reproductive techniques, pregnancy-induced hypertension, and unequal placental sharing were risk factors for the occurrence of discordant twins. The incidence of small for gestational age infants and very low birth weight infants of discordant twins was significantly higher, while the birth weight of discordant twins was significantly lower than those of concordant twins. The duration of hospitalization of discordant twins was longer than that of concordant twins. The incidence of several neonatal complications, such as neonatal respiratory distress syndrome and intracranial hemorrhage, was higher in discordant twins than that in concordant twins. The percentage of those requiring pulmonary surfactant and mechanical ventilation was significantly higher in discordant twins than that in concordant twins.
CONCLUSIONSUse of assisted reproductive techniques, pregnancy-induced hypertension, and unequal placental sharing are perinatal risk factors of discordant twins who are admitted to the neonatal intensive care unit. These infants are also much more likely to suffer from various neonatal complications, especially respiratory and central nervous system diseases. It is important to prevent the occurrence of discordant twins by decreasing these risk factors and timely treatment should be given to discordant twins.
