Purpose: To identify trends in causative bacterial organisms for neonatal sepsis and antimicrobial susceptibilities over 10 years in one neonatal intensive care unit. Methods: We retrospectively reviewed the cases of culture-proven neonatal sepsis between January 1998 and December 2007. The 10-year period was divided into two phases (phase I, 1998-2002; phase II, 2003-2007) to distinguish the differences during the entire period. Results: Total 350 episodes of neonatal sepsis were identified in 315 neonates. The common pathogens of early-onset sepsis were S. epidermidis, S. aureus, P. aeruginosa, and E. cloacae in phase I, and S. epidermidis and E. cloacae in phase II. In cases of late-onset sepsis, coagulase negative Staphylococcus, S. aureus, and K. pneumoniae were isolated frequently in both phases. The incidence of sepsis caused by multi-drug resistant organisms decreased with strict infection control. Gram positive organisms showed 0-20% susceptibility to penicillin, ampicillin, and cefotaxime in both phases. Sensitivity to amikacin for Enterobacter spp. increased, whereas P. aeruginosa showed decreased sensitivity in phase II. Between 50% and 60% of other gram negative bacteria, except P. aeruginosa, were susceptible to cefotaxime in phase II in contrast to phase I. Greater than 80% of gram negative bacteria were sensitive to imipenem except P. aeruginosa and ciprofloxacin in both phases. Conclusion: The trend in causative microorganisms and antimicrobial susceptibilities can be used as a guideline for selection of appropriate antibiotics. A particular attention should be paid to infection control, especially to reduce sepsis caused by multi-drug resistant organisms.

This study was Performed to understand Pediatric Pain management status and nurses' knowledge and attitudes toward it. In addition. it aimed to provide basic data in order to establish effective nursing intervention strategies by confirming the barriers of effective pain management in practice. The subjects were 195 nurses working in pediatric units(general pediatric unit. oncology unit, neonatal unit. neonatal ICU, Pediatric ICU) of 8 university hospitals and one general hospital. Data was collected by the questionnaire from the 3rd of August to the 20th of September in 1999. The instrument developed by Sanna(1999) to measure nurses' knowledge and their attitudes and the other tool by Cleeland(1984) to evaluate barriers in effective Pain management was used. Results of this study are summarized as follows 1. Most nurses learn about the pain management knowledges from through regular curriculum of nursing school(62.0%) And almost nurses(90.8%) don't used to utilize pain assessment tool, but the 'Faces Rating Scale' is the most frequently used by nurses. 2. The use of pain medication(65.6%) is most frequently taken by nurses as pain management and is followed by massage (55.9%) , distraction(27.7%). 3. Nurses' knowledge level is moderate (Mn=3.07). Nurses don't seem to understand pediatric Physical development (Mn = 2.86), psychological development(Mn=2.94) well, meanwhile they seem relatively Quite knowledgeable about the way pain emerges. 4. Nurses' attitudes toward pain is based on behavioral and physiological responses to Pain. They believe 'changes in behavior are a way of assessing pain in child' and 'acute pain increases the number of respiration' Nurses are ready to accept pediatric pain, but are not positive in adopting pain intervention in practice. 5. The barriers of effective pain management are inadequate assessment of pain and pain relief(81.5%), ineffective incorporation among health professionals(80%), and lack of equipment or skills(80.0%).

Purpose : With the development of neonatal intensive care and the increased use of systemic antibiotics, candida sepsis has become one of the most important causes of neonatal morbidity and mortality. The purpose of this study was to investigate the prevalence rate and its associated risk factors. Methods : We retrospectively reviewed medical records of 28 cases with candida sepsis who were admitted in the neonatal intensive care unit(NICU) of Chonnam University Hospital from July 1995 to June 2001. Twenty-nine patients without candida sepsis were enrolled for the control group to verify the risk factors. Results : The overall incidence of candida sepsis was 0.61% for all NICU admissions and 3.68% for all very low birth weight infants with the gradual increase of the annual prevalance rate over time. The endotracheal intubation, percutaneous central vein catheter(PCVC), umbilical vein catheter, total parenteral nutrition, intralipid and dopamine were more applied than the control group (P<0.01 for all). The durations of mechanical ventilator care, central catheter appliance, nothing per os, and admission were also significantly longer than the control group(P<0.01 for all). Ampicillin/ sulbactam, ceftazidime, amikacin, netilmicin, teicoplanin and imipenem/cilastatin were significantly more used than the control group(P<0.05). The durations of ampicillin/sulbactam, ceftazidime, netilmicin and imipenem/cilastatin administration were also proved to be significant as the risk factors(P<0.01). Conclusion : The average annual prevalence rate of candida sepsis in NICU for six years was 0.61% with gradual increasing tendency over time. The elimination of the above risk factors is important in decreasing neonatal morbidity and mortality associated with candida sepsis.
Purpose: Point-of-care tests (POCTs) have the potential to significantly influence management of neonates. The aim of this study was to assess the clinical usefulness of the POCT chemistry analyzer in a neonatal intensive care unit (NICU). Methods: Blood samples of neonates admitted to the NICU were tested using a POCT chemistry analyzer (Piccolo Xpress Chemistry Analyzer, Abaxis, Union City, CA, USA) and a central laboratory chemical analyzer (Chemistry analyzer 7600-110, Hitachi Ltd., Tokyo, Japan) from March to September, 2010. Correlation of 15 analytes between the POCT and the central laboratory machine was evaluated. For consistency of the POCT, three consecutive samplings were performed. Differences among the three tests were recorded. The causes of performance errors were checked through log files. Results: One hundred of 112 pairs of tests for accuracy performed in 54 neonates showed a high correlation between the two machines. Twelve performance errors occurred during the 112 tests. The most common error was insufficient sample error. Eighteen triplet tests performed in 18 patients for consistency revealed a difference range of 3-10%, which was considered to be acceptable. No error occurred during the 54 tests. Conclusion: The POCT is capable of analyzing multiple analytes with a minimal amount of whole blood in a short time. The few performance errors noted presently are likely preventable. This POCT is concluded to be suitable for use as a simple and rapid diagnostic method in the NICU with a minimal amount of blood collected in a less invasive manner.

Purpose : Acinetobacter baumannii is increasingly recognized as an important cause of nosocomial infection, especially in neonatal intensive care units. But little is known about the clinical significance and hospital epidemiology of Acinetobacter species other than A. baumannii. The objective of this study is to describe the clinical characteristics and epidemiology of septicemia due to Acinetobacter species other than A. baumannii. Methods : We retrospectively reviewed 11 cases of blood culture proven nosocomial infection which occured in our neonatal intensive care unit from $4^{th}$ to $24^{th}$, February, 2004. To establish epidemiological analysis, we performed environmental cultures and an antibiogram was obtained from susceptability tests of isolated Acinetobacter species. Results : Clinical manifestations including fever, poor feeding, abdominal distension, diarrhea, bloody stool passage, vomiting, tachypnea and apnea were similar to other infectious diseases. Benign clinical courses were compared with poor prognose, including a high mortality rate in septicemia due to A. baumannii. The major predisposing factor among our patients was the presence of a peripheral intravascular catheter. Antibiogram was similar, but surveillance cultures of environmental specimens failed to identify the source of infection. Conclusion : Acinetobacter species other than A. baumannii were often considered relatively avirulent bacteria, but could be pathologic organisms if cultured in patients with clinical symptoms.
Purpose: To assess the validity of individual and combined prognostic effects of severe bronchopulmonary dysplasia (BPD), brain injury, retinopathy of prematurity (ROP), and parenteral nutrition associated cholestasis(PNAC). Methods: We retrospectively analyzed the medical records of 80 extremely low birthweight (ELBW) infants admitted to the neonatal intensive care unit (NICU) of the Severance Children's Hospital, and who survived to a postmenstrual age of 36 weeks. We analyzed the relationship between 4 neonatal morbidities (severe BPD, severe brain injury, severe ROP, and severe PNAC) and poor outcome. Poor outcome indicated death after a postmenstrual age of 36 weeks or survival with neurosensory impairment (cerebral palsy, delayed development, hearing loss, or blindness) between 18 and 24 months of corrected age. Results: Each neonatal morbidity correlated with poor outcome on univariate analysis. Multiple logistic regression analysis revealed that the odds ratios (OR) were 4.9 (95% confidence interval [CI], 1.0-22.6; $P$=0.044) for severe BPD, 13.2 (3.0-57.3; $P$<.001) for severe brain injury, 5.3 (1.6-18.1; $P$=0.007) for severe ROP, and 3.4 (0.5-22.7; $P$=0.215) for severe PNAC. Severe BPD, brain injury, and ROP were significantly correlated with poor outcome, but not severe PNAC. By increasing the morbidity count, the rate of poor outcome was significantly increased (OR 5.2; 95% CI, 2.2-11.9; $P$<.001). In infants free of the above-mentioned morbidities, the rate of poor outcome was 9%, while the corresponding rates in infants with 1, 2, and more than 3 neonatal morbidities were 46%, 69%, and 100%, respectively. Conclusion: In ELBW infants 3 common neonatal mornidifies, severe BPD, brain injury and ROP, strongly predicts the risk of poor outcome.

Purpose: The aim of this study was to identify the effects of neonatal developmental intervention program (NDT) in promoting motor development and growth and to determine the usefulness of Hammersmith Neonatal Neurological Examination (HNNE) and Neonatal Behavioral Assessment Scale (NBAS) in premature infants. Methods: We performed NDT on selected premature infants (PI, n=42) and compared them with the full term control group (FC, n=20). NDT protocol and development assessment (HNNE, NBAS) were manipulated by the physical therapist in the neonatal intensive care unit. The data of this study were collected prospectively. Results: The PI with GA <34 weeks (VPI) subgroup showed a more use of mechanical ventilator and surfactant, severe bronchopulmonary dysplasia and intraventricular hemorrhage, and patent ductus arteriosus treated surgically than the PI with GA $\geq$34 weeks but less than 37 weeks (LPI) subgroup. The average scores improved significantly in the PI group between the 1st, 2nd, and 3rd assessment by repeated measure (P=0.000). Also, the PI group showed significantly higher total scores and average score at 40 weeks postmenstrual age, P=0.000, respectively than in the FC group. The LPI subgroup showed more weight gain and change in the head circumference between the 1st and 3rd assessment by repeated measure, respectively, P<0.05. The PI group showed no apnea, bradycardia and late sepsis associated with intervention and assessment. Conclusion: The NDT might be a safe and useful intervention to promote motor and growth outcomes in premature infants. Also, the HNNE and NBAS might be safe and useful tools for assessing neurodevelopment in premature infants.
Purpose: The purposes of this study were in understanding maternal and neonatal risk factors for postpartum depression using Edinburgh Postnatal Depression Scale(EPDS). Methods: Among 788 women, who had delivery include cesarean section in the department of obstetrics and gynecology at OO medical center from May 28th 2008 to October 6st 2009, 72 women filled out EPDS questionnaire sheets. Additional aspects included for the analysis are maternal factors including age, number of children, parity, delivery method, and hemoglobin; and neonatal factors such as weight, sex, gestational age, apgar score, and neonatal intensive care unit admission. Comparison was performed between the women with EPDS score equal or less than 8 and the women with EPDS score equal to or higher than 9 using statistical methods of student t-test for linear variables and chi-square test for non-linear variables. SPSS version 13.0 for windows was used for analysis. Results: Thirty women(41.7%) were included in the postpartum depression risk group (EPDS score ${\geqq}9$). Statistically significant difference(P<0.05) was found in gestational ages of the risk group($36.57{\pm}29.6$ weeks) and the non-risk group ($38.10{\pm}1.97$ weeks). Identified statistically significant risk factors(P<0.05) include cesarean section (OR=3.304 [1.121-9.744]), low birth weight infant(OR =6.500 [1.606-26.314]), preterm delivery(OR=2.857[1.071-7.621]), low apgar score (1minute) after delivery (OR=14.909 [1.750-127.025]). There was no statistically significant difference in maternal age, number of children, parity, hemoglobin, neonatal sex, apgar score (5minutes), NICU admission. Conclusions: Through the results showed, gestational age, delivery method, neonatal weight, apgar score(1minute) were identified as risk factors for postpartum depression. To prevent or minimize postpartum depression, oriental medical intervention is recommended for pregnant women through early detection.
Purpose: This study was done to identify the effectiveness of the 'intervention - mother's recorded song' on low-birth weight infants in an neonatal intensive care unit (NICU). Methods: This study was conducted with a nonequivalent control group pre-posttest quasi-experimental design and the participant group was low-birth weight infants who were admitted to the NICU. Forty-eight infants, 24 in each from two groups, the experimental and control group, participated in the study. Results: For physical response according to vital signs, there were no significant statistical differences in heart rate, respiration rate and pulse oximetry saturation between the experimental group and the control group. For behavioral state, there was a significant statistical difference between the experimental and control group. Conclusion: The study results indicate that the intervention using mother's song had some significance as a nursing intervention with positive impacts. Such an intervention can help pediatric nurses improve infants' stabilization of their vital signs and behavioral states. By showing the effectiveness of such an intervention, the results of this study provide further evidence-based information in developing the practice of pediatric nursing.
Purpose: With feasibility in the diagnoses of congenital heart disease (CHD) in the antenatal period, we suspect changes have occurred in its incidence. No data have been reported about the current incidence of simple forms of CHD in Korea. We have attempted to assess the recent incidence and characteristics of CHD in the neonatal care unit of a secondary referral medical center. Methods: Medical records of 497 neonatal care unit patients who underwent echocardiography in the past 5 years were reviewed. Preterm infants with patent ductus arteriosus and other transient, minimal lesions were excluded from this study. Results: Although the number of inpatients remained stable, the incidence of simple forms of CHD showed a gradual decrease over the 5-year study period; a markedly low incidence of complex forms was seen as well. CHD was observed in 3.7% full-term and 6.8% pre-term infants. CHD was observed in 152 infants weighing >2,500 g (3.5% of corresponding birth weight infants); 65 weighing 1,000 to 2,500 g (9.3%); and 6 weighing <1,000 g (8.0%). The incidence of CHD was higher in the pre-term group and the low birth weight group than in each corresponding subgroup (P<0.001); however, the incidence of complex CHD in full-term neonates was high. The number of patients with extracardiac structural anomalies has also shown a gradual decrease every year for the past 5 years. Conclusion: Findings from our study suggest that the recent incidence and disease pattern of CHD might have changed for both complex and simple forms of CHD in Korea.
