Reference limits for osteocalcin in infancy and early childhood: A longitudinal birth cohort study.

OBJECTIVE: The longitudinal variations in serum levels of the hormone osteocalcin is largely unknown during infancy and early childhood. Our aim was to establish reference limits for total serum osteocalcin during specific time points from birth until 5 years of age and present those in the context of sex, breastfeeding practices and gestational age (GA). DESIGN: Blood samples from 551 Swedish children were analysed at birth, 4, 12, 36 and 60 months of age. Total serum osteocalcin was measured using the IDS-iSYS N-MID Osteocalcin assay technique. Information about the mother, birth, anthropometrics and a food diary were collected. RESULTS: Sex-specific and age-specific reference limits were established for the five time points. The median osteocalcin levels over time were 40.8, 90.0, 67.8, 62.2 and 80.9 µg/L for boys and 38.1, 95.5, 78.3, 73.9 and 92.6 µg/L for girls. Lower GA was associated to higher osteocalcin at birth, and ongoing breastfeeding was associated to higher osteocalcin levels. CONCLUSION: Osteocalcin followed a wavelike pattern with low levels in the umbilical cord and a postnatal peak during the first year which then declined and rose again by the age of five. Knowledge of this wavelike pattern and association to factors as sex, breastfeeding and GA may help clinicians to interpret individual osteocalcin levels and guide in future research.

Neonatal healthcare professionals' experiences of intact cord resuscitation in the mother´s bed- an interview study.

BACKGROUND: Intact cord resuscitation in the first three minutes of life improves oxygenation and Apgar scores. The practise of intact cord resuscitation implies the umbilical cord still being connected to the placenta for at least one minute while providing temperature control and equipment for resuscitation. Healthcare professionals described practical challenges in providing intact cord resuscitation. This study aimed to explore neonatal healthcare professionals' experiences of providing intact cord resuscitation in the mother's bed. METHOD: An interview study with an inductive, interpretative approach was chosen and analysed according to reflexive thematic analysis by Braun & Clarke. An open interview guide was used and 20 individual interviews with neonatal healthcare professionals were performed. The study was conducted at five level I-III neonatal care units. In Sweden, resuscitation is performed either in or outside the labour room. RESULTS: The results contributed insight into the participants' experiences of prerequisites for providing neonatal care in intact cord resuscitation. The sense of the mother's vulnerability was noticeable, as the participants reported reducing the risk of exposure to protect and preserve the mother's integrity. The practical challenges in the environment involved working in a limited space. The desire for multi-professional team training comprised education and training as well as debriefing to manage intact cord resuscitation. CONCLUSION: The result of the present study highlights the fact that neonatal healthcare professionals' experiences of providing ICR in the mother's bed were positive and had significant benefits for the neonate, namely zero separation between the neonate and parents and better physical recovery for the neonate. However, the fact that ICR in the mother's bed can be challenging in several ways, such as emotionally, managing environmental circumstances and ensuring effective team collaboration. Therefore, it is of the utmost importance that healthcare professionals are given the opportunity to reflect and train together as a team. Future recommendations are to summarize evidence-based knowledge to design guidelines for ICR situation.

Bilirubin Levels in Neonates ≥35 Weeks of Gestation Receiving Delayed Cord Clamping for an Extended Time-An Observational Study.

OBJECTIVE: To describe bilirubin levels in neonates ≥350/7 gestational weeks, receiving delayed cord clamping (CC), in relation to the updated Bhutani nomogram. STUDY DESIGN: This was a retrospective, observational study based on data from medical records and local data sheets. Singleton neonates, born vaginally at a gestational age ≥350/7, and with a registered time to CC and at least one registered bilirubin, were included. We excluded neonates with positive direct antiglobulin test or hemolytic disorders. Adjusted analyses were performed using ANOVA and linear or logistic regression. RESULTS: We analyzed 558 neonates, mean gestational age (SD) 39.9 (1.3) weeks. CC was performed at a median (IQR) time of 6 (5-8) minutes. The dataset contained 1330 bilirubin measurements. Median (IQR) age at bilirubin measurement was 37 (22-54) hours. Bilirubin percentiles in neonates with CC time ≥2 minutes were similar, or lower, compared with the Bhutani nomogram between 12 and 72 hours, but with greater 95th percentile at later hours of age. Phototherapy was initiated in 13 (2.3 %) of the neonates. We found no association between time to CC and hyperbilirubinemia (ß = -0.05, P = .07). Need for phototherapy was marginally greater in neonates with shorter time to CC. CONCLUSIONS: Bilirubin levels were not correlated to time to CC. Our findings indicate that CC beyond 2 minutes can be performed without additional monitoring for jaundice.

Stabilisation and resuscitation with intact cord circulation is feasible using a wide variety of approaches; a scoping review.

AIM: This scoping review identified studies on approaches to intact cord resuscitation and/or stabilisation (ICR/S) for neonates delivered by Caesarean section (C-section). METHODS: A systematic literature search was carried out using the PubMed, Web of Science, Scopus, Cochrane and CINAHL databases to identify papers published in English from inception to 14 November 2022. RESULTS: We assessed 2613 studies and included 18 from 10 countries, covering 1-125 C-sections: the United States, the United Kingdom, Australia, India, Italy, China, France, The Netherlands, New Zealand and Taiwan. The papers were published from 2014 to 2023, and the majority were randomised controlled trials and observational studies. Different platforms, equipment and staff positions in relation to the operating table were described. Options for resuscitation and stabilisation included different bedding and trolley approaches, and maintaining aseptic conditions was mainly addressed by the neonatal team scrubbing in. Hypothermia was prevented by using warm surfaces, polythene bags and radiant heaters. Equipment was kept easily accessible by mounting it on a trolley or a separate mobile pole. CONCLUSION: We could not reach definitive conclusions on the optimal method for performing ICR/S during a C-section, due to study variations. However, a number of equipment and management options appeared to be feasible approaches.

A hybrid type I, multi-center randomized controlled trial to study the implementation of a method for Sustained cord circulation And VEntilation (the SAVE-method) of late preterm and term neonates: a study protocol.

BACKGROUND: An intact umbilical cord allows the physiological transfusion of blood from the placenta to the neonate, which reduces infant iron deficiency and is associated with improved development during early childhood. The implementation of delayed cord clamping practice varies depending on mode of delivery, as well as gestational age and neonatal compromise. Emerging evidence shows that infants requiring resuscitation would benefit if respiratory support were provided with the umbilical cord intact. Common barriers to providing intact cord resuscitation is the availability of neonatal resuscitation equipment close to the mother, organizational readiness for change as well as attitudes and beliefs about placental transfusion within the multidisciplinary team. Hence, clinical evaluations of cord clamping practice should include implementation outcomes in order to develop strategies for optimal cord management practice. METHODS: The Sustained cord circulation And Ventilation (SAVE) study is a hybrid type I randomized controlled study combining the evaluation of clinical outcomes with implementation and health service outcomes. In phase I of the study, a method for providing in-bed intact cord resuscitation was developed, in phase II of the study the intervention was adapted to be used in multiple settings. In phase III of the study, a full-scale multicenter study will be initiated with concurrent evaluation of clinical, implementation and health service outcomes. Clinical data on neonatal outcomes will be recorded at the labor and neonatal units. Implementation outcomes will be collected from electronic surveys sent to parents as well as staff and managers within the birth and neonatal units. Descriptive and comparative statistics and regression modelling will be used for analysis. Quantitative data will be supplemented by qualitative methods using a thematic analysis with an inductive approach. DISCUSSION: The SAVE study enables the safe development and evaluation of a method for intact cord resuscitation in a multicenter trial. The study identifies barriers and facilitators for intact cord resuscitation. The knowledge provided from the study will be of benefit for the development of cord clamping practice in different challenging clinical settings and provide evidence for development of clinical guidelines regarding optimal cord clamping.

Cord clamping beyond 3 minutes: Neonatal short-term outcomes and maternal postpartum hemorrhage.

BACKGROUND: Delaying cord clamping (CC) for 3-5 minutes reduces iron deficiency and improves neurodevelopment. Data on the effects of CC beyond 3 minutes in relation to short-term neonatal outcomes and maternal risk of postpartum hemorrhage are scarce. METHODS: This was a prospective observational study performed in two delivery departments. Pregnant women with vaginal deliveries were included. Time to CC, estimated postpartum blood loss, and perinatal data were recorded. Spearman's correlation analysis and comparisons between newborns clamped before and after 3 minutes were performed. RESULTS: In total, 904 dyads were included. The mean gestational age ± standard deviation was 40.1 ± 1.2 weeks. CC was performed at a median time of 6 minutes (range 0-23.5). Apgar scores at 5 and 10 minutes were positively correlated with time to CC (correlation coefficient .140, P < .001 and .161, < .001). There was no correlation between CC time and bilirubin level (correlation coefficient .021, P = .54). The median postpartum blood loss was 300 mL (70-2550 mL), with a negative correlation between CC time and postpartum blood loss (-0.115, P = .001). The postpartum blood loss was larger in the group clamped at ≤3 minutes (median [interquartile range] 400 mL [300-600] vs 300 mL [250-450], [P = .003]]. CONCLUSIONS: Umbilical CC times beyond 3 minutes in vaginal deliveries were not associated with negative short-term outcomes in newborns and were associated with a smaller maternal postpartum blood loss. Although CC time as long as 6 minutes could be considered as safe, further research is needed to decide the optimal timing.

Serum osteocalcin levels at 4 months of age were associated with neurodevelopment at 4 years of age in term-born children.

AIM: The hormone osteocalcin influenced neurodevelopment and cognition in mice models; this human study explored potential associations between total serum levels in human infants and neurodevelopment at 4 years of age. METHODS: The data were based on two Swedish birth cohorts from 2008 to 2009. We followed 158 healthy full-term vaginal births (51% girls) by measuring serum osteocalcin in cord blood and at 4, 12 and 36 months. The values were compared with neurodevelopment tests at 4 years of age. RESULTS: There was an association between osteocalcin at 4 months and later full-scale intelligence quotient (IQ; r2 0.031, p < 0.05). Children with osteocalcin levels in the highest quartile scored 5.6 (95% confidence interval [1.3, 9.9]) points higher than those in the lowest quartile, with mean scores of 118.8 ± 8.8 and 113.2 ± 9.2 (p < 0.05). They also scored higher on gross motor skills (p < 0.05) and showed greater ability during the drawing trail test (p < 0.005). Cord levels of osteocalcin were negatively associated with processing speed and fine motor development at 4 years, but levels at 12 and 36 months were not associated with later neurodevelopment. CONCLUSION: Osteocalcin levels in infancy appeared to be associated with later IQ and motor development, but more research is needed.

Challenges imposed by the COVID-19 pandemic on the Obstetrics and Gynecology residency program: a mixed-methods Swedish survey in the COPE Staff cohort study.

BACKGROUND: To outline how the training program and work situation of residents in Obstetrics and Gynecology (OB-GYN) was affected by the pandemic and to illuminate how residents experienced these changes. METHODS: As part of the COVID-19 in Pregnancy and Early Childhood Staff (COPE Staff) cohort study, between January and May 2021, all participating residents were invited to answer a 28-question online Resident Survey focusing on their specialist education, work situation and experiences during the COVID-19 pandemic. Descriptive statistics were given in percentages for categorical variables and means and standard deviations (SD) for continuous variables. Univariate comparative analyses were performed with the use of the Pearson's Chi-2-test for dichotomous data. The association between residents' worry about the quality and length of their specialist training, with extra clinical hours and transfer to other healthcare institutions were assessed by multivariate logistic regression. Free text responses were analyzed by content analysis. RESULTS: Of the 162 participating OB-GYN residents, 69% expressed concern that the pandemic would have a negative impact on their training. Ninety-five (95%) reported cancellation/postponement of educational activities, 70% performed fewer surgeries and 27% had been transferred to other healthcare institutions where about half reported having gained more general knowledge as a physician. Working extra clinical hours was reported by 69% (7.4 ± 5.3 hours per week) and 14% had considered changing their profession due to the pandemic. Senior residents, compared to junior residents, more often experienced cancelled/postponed clinical rotations (30% vs 15%, P=0.02) and reported performing fewer surgeries (P=0.02). The qualitative analysis highlighted the lack of surgical procedural training as a major concern for residents. CONCLUSION: The COVID-19 pandemic has strongly impacted the training program and work situation of OB-GYN residents in Sweden. Residents were concerned over the negative impact of the pandemic on their training program and senior residents reported more missed educational opportunities as compared to junior residents. Program directors, head of institutions and clinical supervisors can use the problem areas pinpointed by this study to support residents and compensate for missed educational opportunities. While hands-on-training and operating time cannot be compensated for, the authors hope that the findings of the study can help develop new strategies to minimize the negative impact of the current and future pandemics on resident education and work situation.

Hepcidin is a relevant iron status indicator in infancy: results from a randomized trial of early vs. delayed cord clamping.

BACKGROUND: We aimed to evaluate whether serum hepcidin is a useful indicator of iron status in infants. METHODS: Term infants (n = 400) were randomized to delayed (≥180 s) or early (≤10 s) cord clamping (CC). Iron status was assessed at 4 and 12 months. In all cases with iron depletion or iron deficiency (ID) (as defined in "Methods") (n = 30) and 97 randomly selected iron-replete infants, we analyzed hepcidin and explored its correlation to the intervention, iron status, and perinatal factors. RESULTS: Serum hepcidin concentrations were significantly lower in the early CC group at both time points and in ID infants at 4 months. Median (2.5th-97.5th percentile) hepcidin in non-ID infants in the delayed CC group (suggested reference) was 64.5 (10.9-142.1), 39.5 (3.5-157.7), and 32.9 (11.2-124.2) ng/mL in the cord blood and at 4 and 12 months, respectively. The value of 16 ng/mL was a threshold detecting all cases of iron depletion/ID at 4 months. No similar threshold for ID was observed at 12 months. The strongest predictor of hepcidin at both ages was ferritin. CONCLUSIONS: Hepcidin is relevant as iron status indicator in early infancy and may be useful to detect ID. Levels <16 ng/mL at 4 months of age indicates ID. IMPACT: Serum hepcidin is a relevant indicator of iron status in early infancy. Normal reference in healthy infants is suggested in this study. Serum hepcidin may be useful in clinical practice to detect iron deficiency.

Neurodevelopmental outcomes of a randomised trial of intact cord resuscitation.

AIM: It has been suggested that intact cord resuscitation can reduce the risk of brain damage. We investigated the effects on neurodevelopment at two years of age. METHODS: This study was performed in Kathmandu, Nepal. In 2016, 231 late preterm and term infants born vaginally and not breathing were randomised to resuscitation with an intact cord or the standard practice of early cord clamping (CC). At two years of age, the World Health Organization's Infant and Young Child Development tool was used to assess the child's neurodevelopment, during telephone interviews with caregivers. RESULTS: We followed up 138 infants (59.7%) at a mean age of 24.8 ± 0.8 months. A significant difference was seen in the development for age Z-score, between the group resuscitated with an intact umbilical cord and the group resuscitated with early CC. The median (range) scores were 1.0 (0.1-2.1) vs 0.9 (-2.0 to 1.8), respectively (P = .04). There was no difference in the motor, language-cognitive and socio-emotional domains. CONCLUSION: Neurodevelopment improvements were observed at two years of age in infants resuscitated with an intact rather than early clamped umbilical cord. No definitive conclusions could be drawn due to protocol violations and a low follow-up rate. More research is needed.

Maternal and perinatal outcomes with COVID-19: A systematic review of 108 pregnancies.

INTRODUCTION: The pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has exposed vulnerable populations to an unprecedented global health crisis. The knowledge gained from previous human coronavirus outbreaks suggests that pregnant women and their fetuses are particularly susceptible to poor outcomes. The objective of this study was to summarize the clinical manifestations and maternal and perinatal outcomes of COVID-19 during pregnancy. MATERIAL AND METHODS: We searched databases for all case reports and series from 12 February to 4 April 2020. Multiple terms and combinations were used including COVID-19, pregnancy, maternal mortality, maternal morbidity, complications, clinical manifestations, neonatal morbidity, intrauterine fetal death, neonatal mortality and SARS-CoV-2. Eligibility criteria included peer-reviewed publications written in English or Chinese and quantitative real-time polymerase chain reaction (PCR) or dual fluorescence PCR-confirmed SARS-CoV-2 infection. Unpublished reports, unspecified date and location of the study or suspicion of duplicate reporting, cases with suspected COVID-19 that were not confirmed by a laboratory test, and unreported maternal or perinatal outcomes were excluded. Data on clinical manifestations, maternal and perinatal outcomes including vertical transmission were extracted and analyzed. RESULTS: Eighteen articles reporting data from 108 pregnancies between 8 December 2019 and 1 April 2020 were included in the current study. Most reports described women presenting in the third trimester with fever (68%) and coughing (34%). Lymphocytopenia (59%) with elevated C-reactive protein (70%) was observed and 91% of the women were delivered by cesarean section. Three maternal intensive care unit admissions were noted but no maternal deaths. One neonatal death and one intrauterine death were also reported. CONCLUSIONS: Although the majority of mothers were discharged without any major complications, severe maternal morbidity as a result of COVID-19 and perinatal deaths were reported. Vertical transmission of the COVID-19 could not be ruled out. Careful monitoring of pregnancies with COVID-19 and measures to prevent neonatal infection are warranted.

Prelabour caesarean section and neurodevelopmental outcome at 4 and 12 months of age: an observational study.

BACKGROUND: With prelabour caesarean section rates growing globally, there is direct and indirect evidence of negative cognitive outcomes in childhood. The objective of this study was to assess the short-term neurodevelopmental outcomes after prelabour caesarean section as compared to vaginally born infants. METHODS: We conducted a prospective, observational study of infants delivered by prelabour caesarean section at the Hospital of Halland, Halmstad, Sweden and compared their development with an historical group of infants born by non-instrumental vaginal delivery. RESULTS: Infants born by prelabour caesarean section were compared with a group of vaginally born infants. Follow-up assessments were performed at 4 and 12 months. Prelabour caesarean infants (n = 66) had significantly lower Ages and Stages Questionnaire, second edition (ASQ-II) scores in all domains (communication, gross motor, fine motor, problem solving and personal-social) at 4 months of age with an adjusted mean difference (95% CI) of - 20.7 (- 28.7 to - 12.6) in ASQ-II total score as compared to vaginally born infants (n = 352). These differences remained for gross-motor skills at the 12 month assessment, adjusted mean difference (95% CI) -4.7 (- 8.8 to - 0.7), n = 62 and 336. CONCLUSIONS: Adverse neurodevelopmental outcomes in infants born by prelabour caesarean section may be apparent already a few months after birth. Additional studies are warranted to explore this relationship further.

Delayed cord clamping was not associated with an increased risk of hyperbilirubinaemia on the day of birth or jaundice in the first 4 weeks.

AIM: Our aim was to investigate the effects of timing of cord clamping on the risk of hyperbilirubinaemia. METHODS: We recruited 540 normal vaginal deliveries at the Paropakar Maternity and Women's Hospital in Kathmandu, Nepal, from October 2 to November 21, 2014. They were randomised into two groups: 257/270 were cord clamped within 60 seconds and 209/270 after 180 seconds. Transcutaneous bilirubin was measured at discharge and 24 hours. At 4 weeks, 506 mothers were successfully contacted by phone, and the health status of the baby and their history of jaundice and treatment was recorded. RESULTS: Based on transcutaneous bilirubin at discharge, 22/261 (8.4%) in the early group and 25/263 (9.5%) in the delayed group (P = 0.76) were at high risk of subsequent hyperbilirubinemia. At the 4-week follow-up, jaundice was reported in 13/253 (5.1%) in the early and 17/253 (6.7%) in the delayed group (P = 0.57) and 3/253 (1.2 %) of the early and 1/253 (0.4%) of the delayed group (P = 0.62) received treatment. All analyses were based on intention-to-treat. CONCLUSION: Delayed cord clamping was not associated with an increased risk of hyperbilirubinaemia during the first day of life or risk of jaundice within 4 weeks compared with the early group.

When age really matters; ferritin reference intervals during infancy revisited.

Infants are at risk for iron deficiency. Despite research advances, assessing iron stores during infancy remains a challenge to the clinician. Ferritin is the first-choice laboratory marker for measuring iron stores but it is today still unclear how to evaluate reference intervals among infants. We have studied Swedish infants (n = 456), born at term after normal pregnancies. Ferritin was measured at birth (umbilical cord sample), 48-72 h, 4 months and 12 months. Lower and upper reference interval limits were constructed as the 2.5th and 97.5th percentiles. By a large study population, we were able to use more stringent measures to avoid interference from the acute phase response than previous reports on ferritin reference intervals. When we used mathematical transformation we furthermore avoided potential information loss in precision and confirmed earlier reports of sex differences. At the lower reference interval limits there were small differences between sexes. For the higher limits, the differences were more pronounced in the older infant. At 0-3 d of age we observed a difference between the sexes of only 5% at the upper limits. The differences peaked at 12 months, where the boys' upper 97.5th percentile was 56% compared to girls.

Reference intervals for reticulocyte hemoglobin content in healthy infants.

OBJECTIVES: Iron deficiency anemia in childhood is a serious public health problem worldwide. Reticulocyte hemoglobin content (Ret-He) is a novel biomarker of iron deficiency adopted for adults but there is a lack of reference intervals for Ret-He in infants. The aim of this study was to provide data from healthy infants. METHODS: Swedish infants (n = 456), born at term after normal pregnancies were included. Ret-He was measured at birth (umbilical cord sample), 48-72 h, 4 months, and 12 months. Reference intervals were calculated as ±2 standard deviations from the mean of Ret-He. RESULTS: Reference intervals for newborn Ret-He were 27.4 to 36.0 pg/L (N = 376) in the cord sample, 28.1-37.7 pg/L (N = 253) at 48-72 h, 25.6-33.4 pg/L (N = 341) at four months and 24.9-34.1 pg/L (N = 288) at 12 months. Ret-He was significantly lower among iron-deficient infants, at 4 months mean difference (95% CI) -4.2 pg/L (-6.1 to -2.4) and at 12 months mean difference (95% CI) -3.4 pg/L (-5.0 to -1.8). CONCLUSIONS: This longitudinal study presents Ret-He reference intervals based on non-anemic and non-iron-deficient infants and constitutes a step towards standardizing Ret-He as a pre-anemia biomarker of iron deficiency in children.

Effect of timing of umbilical cord clamping on anaemia at 8 and 12 months and later neurodevelopment in late pre-term and term infants; a facility-based, randomized-controlled trial in Nepal.

BACKGROUND: Delayed cord clamping at birth has shown to benefit neonates with increased placental transfusion leading to higher haemoglobin concentrations, additional iron stores and less anaemia later in infancy, higher red blood cell flow to vital organs and better cardiopulmonary adaptation. As iron deficiency in infants even without anaemia has been associated with impaired development, delayed cord clamping seems to benefit full term infants also in regions with a relatively low prevalence of iron deficiency anaemia. In Nepal, there is a high anaemia prevalence among children between 6 and 17 months (72-78 %). The objective of the proposed study is to evaluate the effects of delayed and early cord clamping on anaemia (and haemoglobin level) at 8 and 12 months, ferritin at 8 and 12 months, bilirubin at 2-3 days, admission to Neonatal Intensive Care Unit (NICU) or special care nursery, and development at 12 and 18-24 months of age. METHODS/DESIGN: A randomized, controlled trial comparing delayed and early cord clamping will be implemented at Paropakar Maternity and Women's Hospital in Kathmandu, Nepal. Pregnant woman of gestational age 34-41 weeks who deliver vaginally will be included in the study. The interventions will consist of delayed clamping of the umbilical cord (≥180 s after delivery) or early clamping of the umbilical cord (≤60 s). At 8 and 12 months of age, infant's iron status and developmental milestones will be measured. DISCUSSION: This trial is important to perform because, although strong indications for the beneficial effect of delayed cord clamping on anaemia at 8 to 12 months of age exist, it has not yet been evaluated by a randomized trial in this setting. The proposed study will analyse both outcome as well as safety effects. Additionally, the results may not only contribute to practice in Nepal, but also to the global community, in particular to other low-income countries with a high prevalence of iron deficiency anaemia.

Midwives' Experiences of Intact Cord Resuscitation in Nonvigorous Neonates After Vaginal Birth in Sweden.

OBJECTIVE: To describe midwives' experiences of intact cord resuscitation close to the mother for nonvigorous neonates after vaginal birth. DESIGN: Descriptive qualitative. SETTING: Four labor wards in Sweden. PARTICIPANTS: Midwives (N = 13) currently or previously employed in labor wards where the Sustained Cord Circulation and Ventilation (SAVE) study was conducted. METHODS: We analyzed semistructured interviews using reflexive thematic analysis. RESULTS: Participants' experiences are presented in an overarching theme: Midwives balance knowledge with doing the right thing in a challenging work environment during intact cord resuscitation. Three primary themes emerged: A New Workflow, Zero Separation: The Big Advantage, and The Midwife: Guardian of Childbirth. CONCLUSION: The participants were keen to keep the umbilical cord intact even for nonvigorous neonates. They wanted to work with the neonate close to the mother to facilitate zero separation and family participation. Ventilation with an intact umbilical cord was considered a routine to be implemented in the future, but the participants identified certain difficulties with the design of the SAVE study.

Effects of delayed compared with early umbilical cord clamping on maternal postpartum hemorrhage and cord blood gas sampling: a randomized trial.

OBJECTIVE: To investigate the effect of delayed cord clamping (DCC) compared with early cord clamping (ECC) on maternal postpartum hemorrhage (PPH) and umbilical cord blood gas sampling. DESIGN: Secondary analysis of a parallel-group, single-center, randomized controlled trial. SETTING: Swedish county hospital. POPULATION: 382 term deliveries after a low-risk pregnancy. METHODS: Deliveries were randomized to DCC (≥180 seconds, n = 193) or ECC (≤10 seconds, n = 189). Maternal blood loss was estimated by the midwife. Samples for blood gas analysis were taken from one umbilical artery and the umbilical vein, from the pulsating unclamped cord in the DCC group and from the double-clamped cord in the ECC group. Samples were classified as valid when the arterial-venous difference was -0.02 or less for pH and 0.5 kPa or more for pCO2 . Main outcome measures. PPH and proportion of valid blood gas samples. RESULTS: The differences between the DCC and ECC groups with regard to PPH (1.2%, p = 0.8) and severe PPH (-2.7%, p = 0.3) were small and non-significant. The proportion of valid blood gas samples was similar between the DCC (67%, n = 130) and ECC (74%, n = 139) groups, with 6% (95% confidence interval: -4%-16%, p = 0.2) fewer valid samples after DCC. CONCLUSIONS: Delayed cord clamping, compared with early, did not have a significant effect on maternal postpartum hemorrhage or on the proportion of valid blood gas samples. We conclude that delayed cord clamping is a feasible method from an obstetric perspective.
