Purpose: This study aimed to evaluate vitamin D status at birth in very-low-birth-weight infants (VLBWIs: <1,500 g) and to determine the association between vitamin D level and respiratory morbidity. Methods: A retrospective study was conducted at Soonchunhyang University Bucheon Hospital between November 2013 and November 2017. We collected blood samples and data on respiratory morbidity from 230 VLBWIs on the first day of life. Patients who were transferred to other hospitals (n=19), died before 36 weeks of gestational age (n=18), or whose blood samples were not collected immediately after birth (n=5) were excluded. Finally, 188 patients were enrolled. VLBWIs with different vitamin D levels were compared with respect to demographic features, maternal diseases, respiratory morbidities, and other neonatal diseases. Results: The mean serum vitamin D level, as measured by 25-hydroxyvitamin D (25(OH)D), was $13.4{\pm}9.3ng/mL$. The incidence of vitamin D deficiency (<20 ng/mL) was 79.8%, and 44.1% of preterm infants had severe vitamin D deficiency (<10 ng/mL). Logistic analysis shows that a low serum 25(OH)D level (<20 ng/mL) was a risk factor for respiratory distress syndrome (odds ratio [OR], 4.32; P=0.010) and bronchopulmonary dysplasia (OR, 4.11; P=0.035). Conclusion: The results showed that 79.8% of preterm infants in this study had vitamin D deficiency at birth. Low vitamin D status was associated with respiratory morbidity, but the exact mechanism was unknown. Additional studies on the association between vitamin D level and neonatal morbidity are required.

Background: This study was conducted to investigate the epidemiological features, clinical courses, and diagnoses of neonates who are transferred to neonatal intensive care unit of Yeungnam University Hospital due to tachypnea soon after birth. Methods: Based on medical records, we performed a retrospective study of neonatal intensive care unit admissions due to tachypnea from January 2010 to December 2013. Results: A total of 311 neonates were included in this study. The patient characteristics showed male predominance at 2.65:1. Among the 311 neonates with tachypnea, 127 (40.8%) neonates needed oxygen supply, and 54 (17.4%) neonates needed assisted mechanical ventilation. Transient tachypnea of the newborns (TTN) (158, 50.8%) showed the highest incidence, followed by pneumonia (63, 20.3%), extrapulmonary infection (37, 11.9%), respiratory distress syndrome (21, 6.8%), air leak (16, 5.1%), meconium aspiration syndrome (12, 3.9%), congenital heart disease (5, 1.6%), metabolic acidosis (3, 1%), primary pulmonary hypertension of newborns (2, 0.6%) and anemia (2, 0.6%). Conclusion: Although the neonates with tachypnea showed no other respiratory distress symptom, clinicians should be aware of the possibility of other pulmonary diseases as well as TTN and their extra-pulmonary causes. If tachypnea does not improve within a few hours, the clinician should consider further evaluation and management as soon as possible.

We report a case of successful treatment of congenital syphilis in an extremely preterm baby. A 1,395 g female infant was born by emergency Caesarean section due to preterm labor and breech presentation at gestational age at 29 weeks and 3 days with an Apgar score of 2 and 4 at 1 minute and 5 minutes, respectively. The mother of the newborn, an illegal immigrant who did not receive any antenatal care, was diagnosed as active syphilis infection by reactive rapid plasma regain (RPR) (titer 1:128) just before the delivery. Upon birth, the newborn presented with various clinical manifestations, including severe respiratory distress syndrome, persistent pulmonary hypertension of the newborn, disseminated intravascular coagulopathy, desquamation and scaling of the whole body, and osteolytic changes of long bone ends. Results of laboratory tests showed signs of early congenital syphilis, including positive syphilis reagin test (12.7 R.U.), reactive with RPR titer of 1:64, and positive for immunoglobulin (Ig) M and IgG fluorescent treponemal antibody absorption test. However, after completion of penicillin G treatment for two weeks, laboratory results dramatically improved, showing a negative syphilis reagin test (0.5 R.U.) and non-reactive in RPR. In conclusion, the incidence of congenital syphilis is prone to be resurgent in South Korea, neonatologists should be fully aware of the clinical features of congenital syphilis because early diagnosis and prompt treatment are essential in order to reduce the social and economic burden due to congenital syphilis.

목적 본 연구의 목적은 간호대학생을 대상으로 신생아 중환자실에 입원한 호흡곤란증후군 환아 사례의 시뮬레이션 학습 시나리오를 개발하여 지식 적용-기술 수행, 문제 해결 능력, 학습만족도를 파악하는 데 있다. 방법 단일군 사후설계를 적용하였으며, 고위험 아동간호학을 수강하고 있는 간호학과 4학년 55명을 대상으로 총 17개조를 구성하여 매주 3개조(4-5명/조)로 시뮬레이션 운영 후 디브리핑을 60분간 실시하였으며, 자신의 실습 수행에 대한 문제해결능력과 학습만족도를 평가하였다. 결과 시나리오는 간호진단을 포함하여 6단계로 구성하였으며, 20분의 운영 시간 내에 호흡곤란 증후군 환아에 대한 지식 적용 및 기술 수행 능력, OSCE 수행 능력을 평가할 수 있도록 개발하였다. 지식 적용-기술 수행 평가에서 간호진단을 제외한 5개의 범주 중 평가 단계가 지식 적용과 기술 수행 모두 가장 높게 나타났다. 지식 적용에서 가장 높은 평균 점수를 보인 항목은 사정 단계에서 산소포화도 관찰, 평가 단계에서 산소분압과 산소포화도 확인이었고, 기술 수행에서는 중재 단계의 호흡곤란 완화 간호가 높았다. 사정 단계의 검사 확인은 지식 적용 및 기술 수행 영역에서 모두 낮게 나타났다. OSCE 수행 평가에서는 흡인 수행 능력에서는 사용한 물품 정리 및 수행 후 손씻기, 산소 공급에서는 급습기 멸균증류수 확인이 가장 부족한 것으로 나타났으며, 잘 수행된 항목보다 수행되지 못한 항목이 흡인과 산소 공급 모두 많은 것으로 나타나 기본간호술기의 중요성을 확인할 수 있었다. 문제 해결 능력과 학습 만족도는 양의 상관관계가 있는 것으로 나타나 문제 해결 능력이 높을수록 학습만족도가 높은 것으로 나타났다. 결론 시뮬레이션 교육 시행 후 문제 해결 능력에 따라 학습 만족도가 높으므로 문제 해결 능력을 높일 수 있도록 아동간호영역에서 다양한 시뮬레이션 교육 프로그램이 개발될 필요가 있으며, 기본간호술기 수행 능력을 증진할 수 있는 교육 프로그램이 더욱 활발히 운영되어야 한다고 생각된다.

Spontaneous gastric perforation in the newborn is a rare disease that requires early diagnosis and prompt surgical treatment. Between 1988 and 2001 at the Department of Pediatric Surgery. Kyungpool National University Hospital, 9 cases of spontaneous gastric perforation were treated. Seven were males and two females. The mean gestational age and birth weight were 36.7 weeks and 2,455 g respectively. All patients presented with severe abdominal distention and pneumoperitoneum on cross table lateral film of the abdomen. Perforations were located on the anterior wall along the greater curvature of the stomach in six and on the posterior wall along the greater curvature in two. One case showed two sites of perforation on the anterior and posterior wall along the greater curvature. Six patients were managed with debridement and primary closure and the others with debridement and partial gastrectomy. Peritoneal drainage was not performed. There were four deaths; two from sepsis due to leakage from the anastomotic site, one as a result of acute renal failure, and the other by associated respiratory distress syndrome. Spontaneous gastric perforation in the newborn is usually located along the greater curvature. Elevated intragastric pressure is a possible cause of the perforation. Poor prognosis is related to associated diseases and prematurity.

본 연구는 정상 및 호흡곤란 신생아의 혈청내에 존재하는 nitric oxide(NO)의 생성을 관찰하고 erythropoietin (EPO)의 생성을 보기 위하여 정상 신생아 18명과 호흡곤란 신생아 16명으로부터 혈액을 채취하여 혈청내에서의 NO 및 EPO 생성량을 enzyme-linked immunosorbant assay법으로 측정하여 다음과 같은 결과를 얻었다. 1. 정상신생아의 혈청내 nitrite ion은 14.9$\pm$3.2 $\mu$M을 나타냈고 호흡곤란신생아군에서는 12.8$\pm$3.3 $\mu$M을 나타냄으로서 정상 대조군보다 호흡곤란군이 NO생성량이 낮음을 알 수 있었다. 2. 정상신생아의 혈청내 EPO는 16.2$\pm$3.4 mU/ml을 나타냈고 호흡곤란신생아군에서는 21.2 $\pm$5.4 mU/ml을 나타냄으로서 정상 대조군보다 호흡곤란군이 EPO생성량이 많음을 알 수 있었으며 통계학적으로 매우 유의한 차이를 나타냈다. 이상의 결과에서 호흡곤란증후군에서는 정상대조군에 비하여 NO생성이 대체적으로 저하되어 있음을 알 수 있었고 반대로 EPO의 생성은 증가되어 나타남으로서 EPO 상승에 따른 임상증상도 발현될 가능성이 있다하겠다.

조기 양막 파수에 의한 양수 과소증 산모에게서 출생한 미숙아들에게 발생하는 호흡 곤란의 원인으로 폐 저형성증이나 폐고혈압증, RDS, 폐렴 등을 들 수 있다. 이들과 유사한 초기 경과를 보이는 DLS는 이들에 비해 빠른 회복을 보이고 적은 후유증을 남기는 특징을 가져 다른 질환군으로 분류할 수 있다. 본 연구에서는 양수 과소증 산모에게서 출생한 미숙아로 출생 초기심한 호흡 곤란을 보였지만 X-ray 소견이 RDS에 합당하지 않거나 폐 표면 활성제에 반응하지 않았으나 높은 흡기 압력과 NO가스로 치료 후 급속도로 호전되어 DLS로 진단된 2예를 보고하였다. 호흡 곤란을 보이는 미숙아의 치료 시 다른 질환들이 감별되는 경우 DLS를 염두하여 높은 흡기 압력으로 인공 호흡기치료를 하고 심초음파 검사 등을 시행 후 NO 가스의 사용을 적극 고려해야 한다.

In Korea, pulmonary surfactant (PS) replacement therapy in respiratory distress syndrome (RDS) was started in 1991 since when Surfacten$^{(R)}$ was imported from Japan. At the present time, Surfacten$^{(R)}$, Newfactan$^{(R)}$, Curosurf$^{(R)}$, and Infasurf$^{(R)}$ are available in Korea. The governmental health insurance covers the expense for multiple dose treatment since 2002 and the early prophylactic treatment (BW: <1,250 g or GP: <30 wks) since 2011. We undertook a multi-institutional collective study to evaluate the outcomes of PS over past 20 years in Korea (Period-I; 1990/91, P-II; 1996, P-III; 2002, and P-IV; 2007, P-V; 2010). There were 60 RDS neonates with PS treatment in P-I (16 hospitals), 1,179 in P-II (64), 1,595 in P-III (62), 1,921 in P-IV (57), and 3,160 in P-V (72). Decreased mortality rate, defined as the percentage of neonates who died within 28 days of birth, was seen between periods, P-V vs P-I, II, III, and IV (mortality rate: 10.1% vs. 40.0%, 30.0%, 18.7%, and 14.3%). We conclude that PS therapy contributed to improve remarkable outcome in RDS neonates over the last 20 years in Korea. However, more efforts should be made to optimize PS therapy for better outcome. Multiple PS doses for relapse and poor response, early prophylactic use, and better supportive care for pre-term infants are mandatory.

Purpose: The purpose of this study was to explore nursing students' experiences of debriefing after simulation-based learning and to obtain fundamental data to support the development of effective teaching strategies. Methods: Sixty-seven nursing students participated in this study from April to May, 2017. This was a descriptive study analyzing the content of students' descriptions of structured questions in 3 stages (description, analysis, and application) based on recorded videos. Results: The description stage was classified into 3 categories for problem recognition, 4 categories for the nursing plan, and 6 categories for the nursing intervention. The analysis stage was classified into 6 categories for satisfactory practice, 3 categories for experience and 4 categories for what they learned through practice. The application stage was classified into 5 categories, that were to be mastered, and 6 categories, that were important to recognize. Conclusion: This study succeeded in charaterizing learners' experiences of debriefing. During the debriefing, students watched recorded videos, and we found that self-evaluation through structured questionnaires could be a very effective way to strengthen students' core competencies. Our content analysis of the debriefing is expected to contribute to the development of effective strategies in simulation-based education for students and nurses.
