OBJECTIVES. The purpose of this study was to compare the efficiency and safety of exchange transfusion by using peripheral arteries and veins with that of conventional exchange transfusion via the umbilical vein in treating neonatal pathologic hyperbilirubinemia.PATIENTS AND METHODS. We retrospectively reviewed the medical charts of all neonates who had undergone exchange transfusion at our institution from January 1995 to December 2006. Causes of jaundice, efficiency of exchange transfusion in lowering serum bilirubin concentrations, adverse events, and outcomes were recorded. Data were compared between neonates who had undergone exchange transfusion via the peripheral arteries and veins method and those who had undergone exchange transfusion via the umbilical vein method. Data were also compared between stable neonates (body weight > 1500 g without medical problems other than jaundice) and unstable neonates.RESULTS. A total of 123 exchange-transfusion procedures were performed in 102 neonates in the 12-year study period: 24 were performed via the umbilical vein method and 99 via the peripheral vessels method. A total of 87 procedures were performed in 75 stable neonates and 36 in 27 unstable neonates. There was no significant difference in reduction of serum bilirubin level from circulation or the duration of procedures between the 2 methods. Eight neonates died before discharge, but none of the deaths seem to have been attributable to the exchange-transfusion procedure. Severe adverse events occurred more commonly in the umbilical vein group than the peripheral arteries and veins group in the stable neonates. All of the severe and minor events resolved completely without noticeable sequelae before discharge.CONCLUSIONS. Exchange transfusion using peripheral arteries and veins is efficient and effective in reducing serum bilirubin from circulation and is associated with few adverse events. This method should be considered for all neonates requiring exchange transfusion for treatment of neonatal hyperbilirubinemia.

Objectives: Few studies have reported on the relative ratio between the depths to which acupuncture needles are inserted in therapy (therapeutic depth) and safety depth (the distance from the surface of the skin of the acupoint to the transverse fascia). This ratio may be of clinical importance because it may have an impact on the safety and the therapeutic effectiveness of acupuncture. Design: We retrospectively studied children aged 7 to 15 years who underwent abdominal computed tomography (CT) at our hospital during the period January 1997–March 2006. Twelve (12) abdominal acupuncture points (CV-3, CV-4, CV-6, CV-10, CV-12, CV-14, KI-12, ST-24, ST-25, SP-15, LV-13, and LV-4) were measured directly on the CT images. The ratio between the therapeutic depth and safe depth of the 12 abdominal acupoints with factors sex, body weight, age, and waist girths were analyzed by one-way analysis of variance and multiple linear regression analysis. Results: A total of 204 patients were included in this study. There was no significant difference in the therapeutic depth over safety depth ratio (T/S ratio) between genders. The T/S ratio of these 12 acupuncture points ranged from 0.67 to 0.88 and increased significantly with body weight, age, and waist girth (p < 0.001). Conclusions: The therapeutic depth of abdominal acupoints is closer to the safe depth in overweight and in older children aged 7 to 15 years old. There was no significant difference between genders.

Various risk factors are associated with neonatal sepsis; however, its relationship to maternal postpartum fever is unknown. This study aimed to determine the relationship between maternal postpartum fever and neonatal sepsis. Full-term and late preterm stable infants born from January 2019 to June 2021 and whose mothers developed intra- or post-partum fever were included in the study. After the newborns were transferred to the nursery, laboratory assessments were performed. Based on clinical conditions and data, the newborns were divided into unlikely sepsis and probable/proven sepsis groups. Maternal fever onset, duration, and maximum body temperature were recorded. We included 1059 newborns whose mothers developed fever intra-partum (n = 192), post-partum (n = 844), and intra- and post-partum (n = 23). The newborns were grouped into those with unlikely sepsis (n = 550) and those with probable/proven sepsis (n = 509). The incidence of intrapartum fever was higher in the probable/proven sepsis group than in the unlikely sepsis group (27.9% vs. 13.3%, p < 0.001). The incidence of postpartum fever was lower in the probable/proven sepsis group than in the unlikely sepsis group (74.7% vs. 88.5%, p < 0.001). Development of maternal fever within 1.8 h postpartum and a newborn respiratory rate of >60 breaths/min were positive predictors (91.6%) for neonatal probable/proven sepsis.

Objectives: To investigate the survival rate of hydrops fetalis after fetal interventions and neonatal intensive care. Methods: We reviewed the medical records of patients diagnosed with hydrops fetalis from January 2009 to December 2019 at Changhua Christian Children’s Hospital. All cases had abnormal fluid accumulation in at least two body compartments during pre- and postnatal examination. The primary outcome measure was the mortality rate. We also collected information regarding disease etiology, duration of hospital stay, Apgar score, gestational age at birth, initial hydrops fetalis diagnosis, fetal intervention, first albumin and pH levels, and maternal history. Results: Of the 42 cases enrolled, 30 survived and 12 died; the mortality rate was 28.6%. Furthermore, 22 cases received fetal intervention, while 20 cases did not; there was no significant difference in their survival rates (75% and 68%, respectively). Survival rate was associated with gestational age at birth, initial diagnosis time, birthweight, Apgar score, initial albumin and pH levels, and gestational hypertension. Only one case was immune-mediated. Among the nonimmune-mediated cases, the three most common etiologies were lymphatic dysplasia (12/42), idiopathic disorders (10/42), and cardiovascular disorders (5/42). Conclusions: Overall, hydrops fetalis was diagnosed early, and fetal intervention was performed in a timely manner. Preterm births were more frequent, and birthweight was lower in the cases that underwent fetal intervention than in those that did not, but there was no significant between-group difference in mortality. The initial diagnosis time, gestational age at birth, birthweight, Apgar score, and first albumin and pH levels were independently associated with mortality.

Metabolic bone disease (MBD) predominantly affects preterm infants, particularly very-low-birth-weight (VLBW) infants weighing <1500 g. However, there are limited reports on MBD and neurodevelopmental outcomes. This study aimed to analyze the risk factors for MBD and understand its impact on neurodevelopmental outcomes at 2 years of corrected age. Overall, 749 VLBW infants weighing <1350 g at birth were enrolled. Exclusion criteria were major congenital abnormalities, chromosomal abnormalities, and loss of follow-up on the Bayley Scales of Infant Development, Third Edition (BSID-III) test at 24 months of corrected age. Infants were retrospectively assessed by a trained case manager using the BSID-III test at 6, 12, and 24 months old. Infants were categorized as with or without MBD according to radiographic signs. Of those enrolled, 97 VLBW infants were diagnosed with MBD, compared to 362 VLBW infants without MBD. The proportion of infants that completed three follow-ups was 86%. At the assessment at 2 years of age, infants with MBD had lower and more significant differences in motor, language, and cognitive composites. MBD is associated with poor neurodevelopmental outcomes in cognitive, motor, and language composites for VLBW infants at 24 months of corrected age.
