Clinical outcomes of mild to moderate coronavirus disease 2019 patients treated with Regdanvimab in delta-variant outbreak: Retrospective cohort study.

Regdanvimab is a novel neutralizing antibody agent used for the treatment of coronavirus disease 2019 (COVID-19). However, the effectiveness of regdanvimab in delta-variant patients has rarely been investigated. We examined the clinical outcomes and adverse events in COVID 19 patients treated with regdanvimab in the delta-variant era. Data were collected from laboratory-confirmed COVID-19 hospitalized patients who received regdanvimab in 2021 and categorized into pre-delta and delta variant groups. The primary outcome was the need for oxygen therapy. Rescue therapy, clinical improvement, and adverse events were analyzed. Among 101 patients treated with regdanvimab, 31 (30.7%) were delta patients and 49 (48.5) were pre-delta patients. 64.4% were male, the mean age was 60.3 years, and 70 patients (69%) had at least one underlying disease. The median interval from symptom onset to injection was 4 days. Twenty-three patients (23%) needed oxygen therapy, including 9 (29%) in the delta and 8 (16.3%) in the pre-delta group. (P = .176) The risk of early oxygen supplement was higher in the delta group (adjusted hazard ratio (aHR), 6.75; 95% confidence interval(CI), 1.53-29.8). The in-hospital survival rate was 100%, and no patients were admitted to the intensive care unit. Adverse events occurred in 43% of patients:13 (42%) delta patients and 23 (47%) pre-delta patients had any adverse events (P = .661). Patients treated with regdanvimab 4 days after symptom onset showed a favorable prognosis (aHR, 0.26; 95% CI, 0.26-0.91). We found that the high-risk mild to moderate COVID-19 patients treated with regdanvimab showed similar disease progression in delta-variant patients and pre-delta variants; however, we need to be more closely observed delta-variant patients than those in the pre-delta group despite regdanvimab treatment due to rapid disease aggravation.

Survey of Korean daycare personnel on safe sleep practices related to sudden unexplained infant death: a cross-sectional exploratory study.

PURPOSE: Safe sleep practices (SSP) are among the main strategies to reduce sleep-related sudden unexplained infant death (SUID). Daycare personnel must be knowledgeable and trained in SSP related to SUID. This study explored the experience, knowledge, and confidence regarding SSP associated with SUID of daycare personnel. METHODS: A cross-sectional survey was conducted with 395 staff members at 61 daycare centers to measure their experience related to SSP (10 items), related to sleep position and location, bedding materials, and other topics; knowledge of SSP (18 items); and confidence in SSP (1 item) related to SUID. RESULTS: A substantial proportion (23.6%) of respondents used the lateral or prone positions for infant sleep. On average, 4.5 bedding materials were used for infant sleep. Participants showed a lack of knowledge about SSP as indicated by a 56.6% knowledge of SSP related to SUID correct answer rate. Personnel who received SUID education were more knowledgeable and had more confidence regarding SSP than those who did not. More knowledge and confidence related to SSP were associated with better adherence to SSP. CONCLUSION: Standard SSP guidelines should be developed based on South Korea's culture of childcare for educating both childcare professionals and parents at home.

Cultural variation in factors associated with sudden infant death during sleep.

BACKGROUND: Despite the significant reduction decades ago in sudden unexpected death in infancy (SUDI), decline of rates has slowed and stalled in some countries, including the USA. This led to an appreciation of ethnic variations in SUDI rates and the need to increase cultural sensitivity regarding sleep practices and circumstantial factors of SUDI. The study explored SUDI-related factors, in journal articles from two geo-cultural regions (Asian and Western countries), particularly for factors related to infant sleep practices. METHODS: A systematic review was conducted to identify SUDI-related factors in articles from PubMed, Scopus, and the Korean Citation Index from January 1992 to April 2019. From each article, SUDI-related factors were retrieved and categorized through the identification, aggregation, and categorization of factors into the areas of the triple risk model (TRM) of SUDI by their meanings and commonality. Significant trends in the frequency of factors were analyzed across time and between the two geo-cultural regions (Asian and Western countries) of article. RESULTS: From a review of 218 articles (38 Asian and 180 Western articles), 84 SUDI-related factors were identified: 39 factors for TRM 1, 44 factors for TRM 2, and one factor for TRM 3. Four of the top-ranked 10 factors were found in both cultural zones: sleep position, male sex, bed-sharing, and genetics. Both cultural zones identified sleep position (44.0%), bed-sharing (22.0%), and rooming-in (16.5%) as the three most important sleep-related factors for SUDI. Variations between the cultural zones were observed in the place of SUDI occurrence, overheating, swaddling or bedding standards, and smoking. CONCLUSIONS: Regardless of the urgent need to identify SUDI-related factors in low-SUDI societies, Asian cultures showed a significant lack of articles on SUDI. Several sociocultural issues were recognized such as the meaning of bed-sharing and rooming-in, along with residential styles and traditional health beliefs on sleep-related SUDI factors. Particularly little attention towards smoking was found in Asian articles in terms of frequency, suggesting the need to enhance SUDI reduction strategies by incorporating gender-sensitive smoking cessation interventions. This review of SUDI factors requests child health professionals to be alert to sociocultural variations in sleep practices and SUDI factors.

Comparing Inhaler Use Technique Based on Inhaler Type in Elderly Patients with Respiratory Disease.

BACKGROUND: The aim of this study was to investigate inhaler device handling in elderly patients. Inhaler devices with respect to misuse and error correction were also compared. METHODS: Inhaler use technique was assessed using standardized checklists at the first visit and 3-month follow-up visit after retraining. The primary outcome was difference in the acceptable use ratio among inhaler devices. Secondary outcomes included differences in error correction, the most common step of misuse, and factors affecting the accuracy of inhaler use. RESULTS: A total of 251 patients (mean age, 76.4 years) were included. The handling of 320 devices was assessed in the study. All patients had been trained before. However, only 24.7% of them used inhalers correctly. Proportions of acceptable use for Evohaler, Respimat, Turbuhaler, Ellipta, and Breezhaler/Handihaler were 38.7%, 50.0%, 61.4%, 60.8%, and 43.2%, respectively (p=0.026). At the second visit, the acceptable use ratio had increased. There were no significant differences among inhaler types (Evohaler, 63.9%; Respimat, 86.1%; Turbuhaler, 74.3%; Ellipta, 64.6%; and Breezhaler/Handihaler, 65.3% [p=0.129]). In multivariate analysis, body mass index, Turbuhaler, and Ellipta showed positive correlations with acceptable use of inhalers, whereas Chronic Obstructive Pulmonary Disease Assessment Test score showed a negative correlation. CONCLUSION: Although new inhalers have been developed, the accuracy of inhaler use remains low. Elderly patients showed more errors when using pressurized metered-dose inhalers than using dry powder inhalers and soft-mist inhalers. However, there were no significant differences in misuse among inhaler devices after individual training. Results of this study suggests that repeat training is more important than inhaler type.

Development of a Nursing Guideline for Improving Skin Integrity in High-Risk Infants.

BACKGROUND: High-risk infants are highly susceptible to skin impairment caused by invasive procedures, radiant warmers, and phototherapy, in addition to their intrinsic vulnerability. This leads to a vicious cycle that aggravates the risk of skin infections. Concerns have been raised that neonatal nurses may lack knowledge regarding feasible guidelines to improve skin integrity of high-risk newborns. METHOD: A clinical guideline was developed for neonatal skin care practices based on skin physiology, and its educational effects on the knowledge and confidence of neonatal nurses was evaluated. A booklet was developed on skin care practice guidelines divided into topics determined through a nationwide survey. RESULTS: Using a quasi-experimental design with 46 neonatal nurses, education with this booklet improved nurses' knowledge of skin care practices but not their confidence. CONCLUSION: These findings highlight the importance of implementing a tailored systematic program rather than a single educational session on skin care in high-risk infants for neonatal nurses.

Risk Factors for Sudden Infant Death Syndrome and Sleeping Practices in Korea.

Sudden infant death syndrome (SIDS) in Korea remains a poorly-understood subject for both professionals and the public. Recent reports have emphasized ethnic differences in SIDS rates, suggesting that making adjustments in child-rearing practices may contribute substantially to SIDS reduction. Two of the three major risk factors for SIDS-vulnerability of the infant and exogenous factors-need to be understood in particular depth due to their broad scope and sociocultural grounding. This paper presents substantial issues regarding preterm birth and male gender on infants' vulnerability to SIDS in Korea. Practices of caring for healthy infants are addressed in the context of sleeping practices, including sleeping position, bedding arrangements, sleeping on the floor, the back-to-sleep position, high indoor temperatures and ondol floor heating, and swaddling. Professional and social awareness about how to reduce SIDS should be raised by promoting a better understanding of risk factors in the context of ethnic and cultural variations in child-rearing practices.

[Glucose Variations in the First Day of Life of Newborns under Observational Surveillance]. / 관찰감시를 요하는 ì €ìœ„í—˜ì‹ ìƒì•„ì˜ 생후 초기 혈당변이 탐색.

PURPOSE: Nursing protocols for glucose management are well known for both healthy term newborns and high-risk newborns. However, for less risky newborns who are under only observation surveillance, hypoglycemia could be overlooked unless clinical symptoms develop. METHODS: A retrospective study was performed to explore factors influencing variations in glucose levels in 91 newborns who did not require any interventions, but were under nursing surveillance, at a level II neonatal intensive care unit. Data were retrieved from electrical medical records on glucose levels, demographic characteristics, and other clinical characteristics of newborns in their first day of life from January 2016 to May 2019. RESULTS: Glucose levels tended to stabilize within the normal range (60~80 mg/dL) as time passed during the first day of life. Cesarean section, multiple gestation, abnormal growth, and later preterm birth were associated with low glucose levels in the first 2 hours of life. Thirty-one newborns experienced a hypoglycemic episode (< 45 mg/dL) during the first 24 hours of life. CONCLUSION: The findings of this study support the active encouragement of early feeding within 2 hours of birth and urgent adoption of a structural protocol for glucose surveillance in newborns with potential health problems immediately after birth.

Knowledge on sudden unexplained infant death-related safe sleep practices and infant cardiopulmonary resuscitation in pediatric nurses.

PURPOSE: Sudden unexplained infant death (SUID) is a major contributor to infant mortality, and pediatric nurses have the responsibility to educate parents on SUID-reducing strategies. This study was conducted to measure pediatric nurses' knowledge of SUID-related safe sleep practices (K-SSSP) and infant cardiopulmonary resuscitation (K-ICPR). METHODS: In total, 136 pediatric nurses were administered a survey including K-SSSP (13 items), K-ICPR (5 items), confidence in K-SSSP education (1 item; 5 points), and other factors relating to SUID experiences or education. RESULTS: The correct answer rates of the K-SSSP and K-ICPR were 62.6% and 62.5%, retrospectively. The mean score for confidence in K-SSSP education was 2.6±0.9. Only 18 nurses (13.2%) responded that they educated parents on the content of the K-SSSP, while 76 nurses had received education on SUID. Positive relationships were observed between K-SSSP scores and higher education, between K-ICPR scores and having own child(ren) and clinical experience, and between confidence in K-SSSP education and higher education or having one's own child(ren). Nurses caring for newborns performed more SUID education than nurses working in other units. CONCLUSION: There is a profound need to implement a systemic educational program on SUID and strategies to reduce SUID for pediatric nurses.

[Cognitive Ability and Related Factors in Preschoolers Born Prematurely]. / 미숙아로 출생한 í•™ë ¹ì „ê¸° 아동의 ì¸ì§€ëŠ¥ë ¥ê³¼ 영향요인.

PURPOSE: This study was conducted to evaluate cognitive ability in preschoolers born prematurely and to investigate related factors. METHODS: A prospective, longitudinal study was conducted with 64 children at 5-6 years of corrected age (CA) (second follow-up) among 76 children who had been assessed at 2.0~3.5 years of CA (first follow-up) from a sample of 343 preterm infants born from 2008 to 2010. To evaluate each child's cognitive ability, during a home visit, we used the Kaufman Assessment Battery for Children-II (KABC-II) at the second follow-up. To explore factors related to cognitive ability, we measured children's hemoglobin level at the second follow-up and used the data collected in our previous study, including the Bayley Scale of Infant Development-II (BSID-II) at the first follow-up. RESULTS: The mean total KABC-II quotient was 117.0±14.4. The 5-minute Apgar score (ß=.29, p=.006), hemoglobin level (ß=.22, p=.032), and the mental development index quotient of the BSID-II (ß=.51, p<.001) were statistically significant predictors of the KABC-II quotient in multiple linear regression analysis. CONCLUSION: The cognitive function of young children born prematurely was influenced by early neurodevelopment and factors reflecting their health status, such as anemia and a low 5-minute Apgar score.

Development of a questionnaire for the assessment of quality of life in korean children with allergic rhinitis.

PURPOSE: Korean children have their own unique lifestyle based on their living environment and culture. This study aimed to develop a questionnaire to evaluate the quality of life in Korean children with allergic rhinitis. METHODS: After a preliminary survey, an initial questionnaire was developed. Questions were modified to be easily understood by young children aged 6 to 7 years. The modified questionnaire was tested on children aged 6 to 12 years old. Item scores, defined as the proportion of children whose answer score was 1 point or higher was multiplied by the average answer score of each question, were used to identify questions that have practical application to the quality of life in Korean children with allergic rhinitis. Differences in answer scores between children with allergic rhinitis and those who were healthy were assessed by a Wilcoxon rank-sum test. The relationship between nasal index scores and quality of life scores was determined by a Spearman rank order test. RESULTS: An initial questionnaire was composed of 21 items. We identified 19 questions with item scores above 0.5 in children with allergic rhinitis, many of which were related to nasal symptoms and 10 questions that were different between the allergic rhinitis group and the control group. The final questionnaire included the 10 questions that had both high item scores and a significant difference in the answer scores between the two groups. CONCLUSIONS: The developed questionnaire is essential and practical for assessing discomfort related to the symptoms felt by Korean children with allergic rhinitis.

[Evaluation of mental status in high-risk neonates using infants coma scale].

PURPOSE: This was a cross sectional descriptive study to introduce the Infants Coma Scale (ICS), describe mental status of high risk infants using ICS and explore the relationships between ICS and clinical variables in infants hospitalized in a neonatal intensive care unit of a university hospital in Korea. METHODS: After ICS was developed and tested by the authors, a research nurse evaluated the mental status of the infants using the English version of ICS and obtained clinical information on the infants from their medical records. RESULTS: Data from 88 infants were analyzed. About 60% were male, 90% were preterm births, and 40% had pathologic abnormalities. Their mean gestational age was 32.4 (+/-3.50) weeks and the mean birth weight was 1,842 (+/-728.6) grams. The Cronbach's alpha for the ICS was .78. There was a statistically significant positive correlation between ICS total score and five clinical variables including gestational age, birth weight, 1 and 5 min Apgar scores and respiration status. CONCLUSION: Mental status is an important parameter in nursing assessment. ICS is a valid and reliable instrument, which clinicians can easily use to evaluate the mental status of high risk infants.

[Comparison in weight, height, degree of obesity and body mass index among different methods for body shape classification in school-age children].

PURPOSE: The study was conducted to describe body shapes of school age children using the degree of obesity index (DOI) and body mass index obesity index classified by the Ministry of Education, Science and Technology (M-BOI) and Seoul Metropolitan Office of Education (S-BOI). METHODS: In this cross sectional descriptive study health screening data for school children collected in 2007 was used. RESULTS: Data were analyzed for 2,193 4th-6th grade boys (52%) and girls who attended 4 schools in rural areas. DOI determined that only 44.3% of students had average weight. This proportion was much lower than the results of other methods (74.3-77.6%). All three methods defined girls (51.3-61.8%) as skinnier than boys. Skinny and average body shaped children classified by DOI and obese children classified by S-BOI were heavier and taller and presented higher degrees of obesity (DO) and BMI scores than by other methods. M-BOI and S-BOI presented statistically significant positive correlations with weight, height, DO and BMI, while DOI was not correlated with height. CONCLUSION: BMI based body shape classifications provide a more rigorous classification of body shape which are favorable for school health professionals with limited resources and policy makers for internationally comparable references.

Parental Perception of Neonates, Parental Stress and Education for NICU Parents.

PURPOSE: The purpose of this study was to conduct a comparative analysis between the perception of parents with premature infants in the NICU and parents with full-term newborns, and in the process to evaluate the effects of NICU educational support on parents with regard to their perception of neonate and parental stress. METHODS: A mixed quantitative design was employed to compare parental perception of neonates using the Neonatal Perception Index (NPI) between the parents of 26 full-term infants (full-term group) and the parents of 22 premature infants in the NICU (NICU group), and also to evaluate the effect of NICU educational support on NPI and parental stress using the Parental Stress Scale (PSS) between the mothers and fathers in the NICU group. RESULTS: NICU mothers showed the lowest NPI score among full-term and NICU parents. However, no difference in direction of NPI scores was observed between parents in either the full-term or NICU group. NICU education improved NPI and decreased PSS in fathers but not in mothers. CONCLUSION: Environmental modifications of the nursery setting, particularly its remote location to the NICU, could improve mothers' perception of full-term neonates. NICU mothers, as the principal care- givers, may suffer from culturally-grounded, psychoemotional disturbances after giving birth to a sick infant, which may not be applicable to fathers. The quality of family-centered care in the NICU environment, parental role alteration, and the condition of infants need to be improved to decrease parental stress in the NICU. Fathers may have significant potential in caring for mothers and sick infants during the transition to parenthood. Education for NICU parents should be done for both mothers and fathers in the acute postpartum period.

[The relationship between early neo-maternal exposure, and maternal attachment, maternal self-esteem and postpartum depression in the mothers of NICU infants].

PURPOSE: This study was performed to investigate the quantities of three neo-maternal exposures; visiting frequency, auditory contact and physical contact, and to examine the relationship between the quantities of each exposure and maternal attachment, maternal self-esteem and postpartum depression in 40 mothers of NICU babies during the first week in the NICU. METHOD: Each neo-maternal exposure was counted at every mother's visit to the newborn and maternal attachment, maternal self-esteem and postpartum depression were measured using the maternal attachment inventory, the maternal self-report inventory and Edinburgh Postpartum Depression Scale (EPDS) on the first and seventh day in the NICU. RESULT: The Mean of each neo-maternal exposure was 8.77(2.81) for the visiting frequency, 5.82(3.66) for the auditory contact and 5.60(2.89) for the physical contact during 7 days in the NICU. No significant changes were found in the scores of maternal attachment, maternal self-esteem and postpartum depression between the first and the seventh day in the NICU. The quantities of neo-maternal exposures were positively related to the scores of maternal attachment and maternal self-esteem but not related to postpartum depression. CONCLUSION: The results of the study suggest the lack of early neo-maternal exposure in cases of NICU hospitalization negate its beneficial effects on maternal psychological well-being in increasing maternal attachment and self-esteem. More efforts are needed for the neo-maternal interaction and the reevaluation of NICU visitation hours in order to promote maternal-infant interaction.

[Concept analysis of endotracheal suctioning (ETS)].

PURPOSE: Concept analysis was performed on the behavioral concept of endotracheal suctioning (ETS), to identify the goal, to develop a standardized clinical protocol, to identify the antecedents and consequences, and to differentiate the improper use of ETS. METHOD: Walker & Avant's concept analysis was employed using clinical guidelines, books and review articles in which the procedures of ETS were written in detail and published in Pubmed within the last 20 years. RESULT: The macro-goal of ETS was to remove accumulated respiratory secretions. Three defining attributes of ETS were identified; catheter, suctioning and asepsis. Each attribute involved empirical referents, such as the size and depth of the catheter, the suction pressure, duration and method for suctioning. The antecedents of ETS were identical to the clinical evidences for the need of ETS such as the nursing assessment data. The consequences of ETS serve as an evaluation criteria on the effects of ETS based on the goal of ETS. CONCLUSION: The concept analysis of ETS demonstrates an example of considering a specific nursing protocol of ETS as a behavioral concept, applying concept analysis to it to identify it's key behavioral components as defining attributes and empirical referents and then developing and applying the standard ETS protocol.

[Coincidence analysis of keywords of the Journal of Korean Academy of Nursing with MeSH].

PURPOSE: We try to disclose how much the keywords of the papers from the Journal of the Korean Academy of Nursing coincide with MeSH terminologies and to understand the major subjects of the recent nursing research in Korea from keywords. METHODS: Keywords of journals were extracted and compared with MeSH terms. The frequency of the appearance of each keyword was sorted by a descending order. RESULTS: Coincidence rate of 1,235 keywords with MeSH terms was 51.6%. Out of them, depression, elderly, stress, self efficacy, quality of life, exercise, middle-aged women, and women appeared most frequently in descending order. CONCLUSION: Coincidence rate of the keywords with MeSH terms was at an acceptable level, however to improve it, the education of submitters and editorial board members are required, as well as the copy editor, to take a role in checking keywords. To infer the subjects of the research from keywords might well represent the recent topics of research work.

[The effects of the systemic follow up health care program on the health promotion and the risk reduction in premature infants and their mothers].

PURPOSE: This research was conducted to evaluate the effects of a systemic follow-up care program on health promotion and risk reduction in 64 high-risk infants (HRI) including premature infants and their mothers. METHOD: The intervention consisted of systemic NICU education, tele-counseling and 3 home visits in 6 months. The subjects were divided into either the intervention group or the control group receiving the conventional education without the tele-counseling and home visiting. Infant health promotion was measured using physical assessment, types of health problems, reflexes, OPD visiting history, DDST, immunization, feeding assessment, Infant death rate, etc. Maternal self-esteem, postpartum depression and family function were measured using the maternal self-report inventory (MRI), EPDS, and family apgar score (Fapgar), retrospectively. RESULT: All premature infants in the intervention group were in the normal range of growth and development, and the regular vaccination schedule. The health problems in the intervention group were addressed early so not to develop into adverse effects. The follow-up program for 6 months showed beneficial effects on MRI, EPDS, and Fapgar. CONCLUSION: A systemic follow-up health care program is beneficial on health promotion and risk reduction in 64 HRI including premature infants and their mothers.

The effects of a home-visiting discharge education on maternal self-esteem, maternal attachment, postpartum depression and family function in the mothers of NICU infants.

PURPOSE: A quasi-experimental study was performed to investigate the effects of a home visiting discharge education program on the maternal self-esteem, attachment, postpartum depression and family function in 35 mothers of neonatal intensive care unit (NICU) infants. METHODS: Twenty-three mothers in the intervention group received the home visiting discharge education while 12 mothers in the control group received the routine, hospital discharge education. Baseline data was collected in both groups one day after delivery. The intervention group received the home visiting discharge education while the control group did the routine hospital-based discharge education. The questionnaire including the data on maternal self-esteem, attachment, postpartum depression and family function were collected within 1 week after the discharge by mail. RESULTS: The scores of maternal self-esteem, and attachment were significantly increased, and the postpartum depression and the family function score were decreased after the home visiting discharge education in intervention group. There were no changes in these variables before and after the routine hospital-based discharge education in control group. CONCLUSION: These results support the beneficial effects of home visiting discharge education on the maternal role adaptation and family function of the mothers of NICU infants.

[Comparison of maternal self-esteem, postpartal depression, and family function in mothers of normal and of low birth-weight infants].

PURPOSE: The study investigates the degree of maternal self-esteem, postpartal depression, and family function in mothers of normal and of low birth-weight infants. METHOD: A retrospective cohort design was applied to compare the variables of interest between a group of 73 mothers with normal birth weight infants and a group of 45 mothers with low birth-weight infants, using the maternal self-report inventory(MSRV), Edinburgh Postnatal Depression Scale(EPDS) and Family APGAR(FAPGAR). RESULT: The total mean score was 82.57 for MSRV, 8.45 for EPDS, and 6.83 for FAPGAR with no differences between two groups. A positive correlation was found between MSRV and FAPGAR, while a negative correlations between MSRV and EPDS, and FAPGAR and EPDS. Regardless of the direction of the relationship, the degrees of the correlations were stronger in low birth-weight mothers group than in normal group. CONCLUSION: No differences in MSRV, EPDS and FAPGAR between the normal and the low birth-weight group considered as beneficial effects of the follow-up management which low birth-weight group was engaged in. This suggested the early intervention(follow-up) for the family with risk factor(low birth-weight) could reduce negative outcomes such as the impaired maternal self-esteem and family function, and the occurrence of postpartal depression, retrospectively.

[Assessment of neonatal hyperbilirubinemia using a transcutaneous bilirubinometry].

PURPOSE: The purpose of the study is to investigate the relationship between total serum bilirubin(TSB) and transcutaneous bilirubinometry(TcB) in neonates with jaundice. METHOD: TcB from various sites(forehead, sternum, abdomen, buttock, hand, dorsalis-pedia) was measured using a JM-102 in a total of 102 neonate, 42 female and 60 male, with the mean 37.5 gestational week and the mean 2,903 gram of birth weight, as well as TSB from capillary punctures. RESULT: The mean bilirubin was 11.73 in serum, 20.55 on the forehead, 17.23 on the sternum, 16.19 on the abdomen, 18.22 on the buttock, 15.83 on the hand and 15.49 on the dorsalis-pedia. The relationship between TSB and TcBs were formulated by simple regression with 0.406 < r < 0.668(p <.000). A higher relationship was revealed between TSB and TCB at the forehead in infants of full-term, ABO incompatibility, and Hb greater than 16 mg/dl(r = 0.725, 0.790, and 0.717, retrospectively). Phototherapy altered the measurement of TcB per site. CONCLUSION: TcB on the forehead is a reliable, noninvasive and convenient measurement of TSB in normal infants(Institutions need to establish quantitative equations representing the specific relationship between TSB and TCB according to the hemodynamic problems of infants such as ABO incompatibility, or low Hb).
