RESUMO
Objective: To compare the effect of Delayed Cord Clamping (DCC) to Immediate Cord Clamping (ICC) on phototherapy treatment in a cohort of cesarean-delivered newborns with AB0-alloimmunization. Study Design: In a retrospective cohort study neonates with Gestational Age (GA) ≥ 35 weeks and diagnosed with AB0-alloimmunization before implementation of DCC (ICC group) were compared with neonates born after implementation (DCC group). The primary outcome was the need for phototherapy. Secondary outcomes included hospital stay, readmission rate, need for extra intravenous fluids, maximum bilirubin concentration, and hours of life at bilirubin peak. We used regression models to adjust for weight loss, type of feeding, birth weight, and gestational age. Results: In total 336 neonates were included, of which 192 neonates in the ICC group and 144 in the DCC group. There were no differences in basic characteristics between the two groups except for birth weight (ICC 3193 ± 468 g vs. DCC 3053 ± 446 g, p = 0.01) and GA (ICC 38.2 ± 1 weeks of GA, vs. DCC 37.9 ± 1 weeks of GA; p = 0.01). When adjusted for confounding factors, after implementation of DCC, significantly more infants with AB0 alloimmunization needed phototherapy (22.4% vs. 36.8%, RR 1.61 CI: 1.15-2.28; p = 0.006; Number Needed to Harm 7), needed to stay longer in hospital (20.3% vs. 30.5%, RR 1.53 CI: 1.05-2.23; p = 0.03). The maximum bilirubin was higher (11.4 ± 4.0 mg/dl vs. 12.9 ± 3.5 mg/dl, p < 0.001) and occurred later [74 (67-92) hours vs. 84 (70-103) hours; p = 0.04]. There was no difference in the need for intravenous fluids (1.6% vs. 4.9%; not significant) and readmissions (1.6% vs. 3.5%; not significant). Conclusion: Infants with AB0 alloimmunization needed more often phototherapy and were admitted longer after implementation of DCC policy. Further studies are needed to see whether the benefit of DCC outweighs the increased morbidity, admission days, and related hospital costs.
RESUMO
OBJECTIVE: To assess the accuracy of pulse oximetry screening for critical congenital heart defects (CCHDs) in a setting with home births and early discharge after hospital deliveries, by using an adapted protocol fitting the work patterns of community midwives. STUDY DESIGN: Pre- and postductal oxygen saturations (SpO2) were measured ≥1 hour after birth and on day 2 or 3. Screenings were positive if the SpO2 measurement was <90% or if 2 independent measures of pre- and postductal SpO2 were <95% and/or the pre-/postductal difference was >3%. Positive screenings were referred for pediatric assessment. Primary outcomes were sensitivity, specificity, and false-positive rate of pulse oximetry screening for CCHD. Secondary outcome was detection of noncardiac illnesses. RESULTS: The prenatal detection rate of CCHDs was 73%. After we excluded these cases and symptomatic CCHDs presenting immediately after birth, 23 959 newborns were screened. Pulse oximetry screening sensitivity in the remaining cohort was 50.0% (95% CI 23.7-76.3) and specificity was 99.1% (95% CI 99.0-99.2). Pulse oximetry screening was false positive for CCHDs in 221 infants, of whom 61% (134) had noncardiac illnesses, including infections (31) and respiratory pathology (88). Pulse oximetry screening did not detect left-heart obstructive CCHDs. Including cases with prenatally detected CCHDs increased the sensitivity to 70.2% (95% CI 56.0-81.4). CONCLUSION: Pulse oximetry screening adapted for perinatal care in home births and early postdelivery hospital discharge assisted the diagnosis of CCHDs before signs of cardiovascular collapse. High prenatal detection led to a moderate sensitivity of pulse oximetry screening. The screening also detected noncardiac illnesses in 0.6% of all infants, including infections and respiratory morbidity, which led to early recognition and referral for treatment.

OBJECTIVES: To assess the feasibility of pulse oximetry (PO) screening in settings with home births and very early discharge. We assessed this with an adapted protocol in The Netherlands. STUDY DESIGN: PO screening was performed in the Leiden region in hospitals and by community midwives. Measurements were taken ≥ 1 hour after birth and on day 2 or 3 during the midwife visit. Primary outcome was the percentage of screened infants with parental consent. The time point of screening, oxygen saturation, false positive (FP) screenings, critical congenital heart defects (CCHDs), and other detected pathology were registered. RESULTS: In a 1-year period, 3625 eligible infants were born. Parents of 491 infants were not approached for consent, and 44 refused the screening. PO screening was performed in 3059/3090 (99%) infants with obtained consent. Median (IQR) time points of the first and second screening were 1.8 (1.3-2.8) and 37 (27-47) hours after birth. In 394 infants with screening within 1 hour after birth, the median pre- and postductal oxygen saturations were 99% (98%-100%) and 99% (97%-100%). No CCHD was detected. The FP prevalence was 1.0% overall (0.6% in the first hours after birth). After referral, important noncritical cardiac and other noncardiac pathology was found in 62% of the FP screenings. CONCLUSIONS: PO screening for CCHD is feasible after home births and very early discharge from hospital. Important neonatal pathology was detected at an early stage, potentially increasing the safety of home births and early discharge policy.

OBJECTIVE: to evaluate the feasibility of using pulse oximetry (PO) for evaluating infants born in community-based midwifery care. DESIGN: a prospective, observational study of infants born after midwifery supervised (home) births. SETTING: 27 midwives from seven practices providing primary care in (home) births used PO at birth or the early puerperal period over a ten-month period. Data were obtained on the effect of PO on outcome, interventions and decision-making. Midwives were surveyed about applicability and usefulness of PO. PARTICIPANTS: 153 infants born in primary midwifery care. FINDINGS: all births were uncomplicated except for one infant receiving supplemental oxygen and another was mask ventilated. In 138/153 (90%) infants PO was successfully used and 88% of midwives found PO easy to use. In 148/153 (97%) infants PO did not influence midwives' clinical judgment and referral policy. In 5/153 (3%) infants, midwives were uncertain of the infant's condition, but PO measurements were reassuring. In case of suboptimal neonatal condition or resuscitation, 100% of midwives declared they would use PO again. KEY CONCLUSIONS: it is feasible to use PO in community based midwifery care, but not considered an important contribution to routine evaluation of infants. Midwives would like to have PO available during suboptimal neonatal condition or when resuscitation is required. IMPLICATIONS FOR PRACTICE: PO can be applied in community based midwifery care; it does not lead to insecurity or extra referral. Further research on a larger group of infants must show the effect of PO on neonatal outcomes.

BACKGROUND: Despite limited data, international guidelines recommend the use of intravenous immunoglobulin (IVIg) in neonates with rhesus hemolytic disease. OBJECTIVE: We tested whether prophylactic use of IVIg reduces the need for exchange transfusions in neonates with rhesus hemolytic disease. DESIGN AND SETTING: We performed a randomized, double-blind, placebo-controlled trial in neonates with rhesus hemolytic disease. After stratification for treatment with intrauterine transfusion, neonates were randomly assigned for IVIg (0.75 g/kg) or placebo (5% glucose). The primary outcome was the rate of exchange transfusions. Secondary outcomes were duration of phototherapy, maximum bilirubin levels, and the need of top-up red-cell transfusions. RESULTS: Eighty infants were included in the study, 53 of whom (66%) were treated with intrauterine transfusion(s). There was no difference in the rate of exchange transfusions between the IVIg and placebo groups (7 of 41 [17%] vs 6 of 39 [15%]; P = .99) and in the number of exchange transfusions per patient (median [range]: 0 [0-2] vs 0 [0-2]; P = .90) or in duration of phototherapy (4.7 [1.8] vs 5.1 [2.1] days; P = .34), maximum bilirubin levels (14.8 [4.7] vs 14.1 [4.9] mg/dL; P = .52), and proportion of neonates who required top-up red-cell transfusions (34 of 41 [83%] vs 34 of 39 [87%]; P = .76). CONCLUSIONS: Prophylactic IVIg does not reduce the need for exchange transfusion or the rates of other adverse neonatal outcomes. Our findings do not support the use of IVIg in neonates with rhesus hemolytic disease.
