Umbilical cord clamping practices of U.S. obstetricians

Thermoregulation-Focused Implementation of Delayed Cord Clamping among <34 Weeks' Gestational Age Neonates

OBJECTIVE

 Delayed cord clamping (DCC) is recommended for all neonates; however, adapting such practice can be slow or unsustainable, especially among preterm neonates. During DCC neonates are exposed to a cool environment, raising concerns for neonatal hypothermia. Moderate hypothermia may induce morbidities that counteract the potential benefits of DCC. A quality improvement project on a thermoregulation-focused DCC protocol was implemented for neonates less than 34 weeks' gestational age (GA). The aim was to increase the compliance rate of DCC while maintaining normothermia.

STUDY DESIGN

 The DCC protocol was implemented on October 1, 2020 in a large Level III neonatal intensive care unit. The thermoregulation measures included increasing delivery room temperature and using heat conservation supplies (sterile polyethylene suit, warm towels, and thermal pads). Baseline characteristics, the compliance rate of DCC, and admission temperatures were compared 4 months' preimplementation and 26 months' postimplementation RESULTS:  The rate of DCC increased from 20% (11/54) in preimplementation to 57% (240/425) in postimplementation (p < 0.001). The balancing measure of admission normothermia remained unchanged. In a postimplementation subgroup analysis, the DCC cohort had less tendency to experience admission moderate hypothermia (<36°C; 9.2 vs. 14.1%, p = 0.11). The DCC cohort had more favorable secondary outcomes including higher admission hematocrit, less blood transfusions, less intraventricular hemorrhage, and lower mortality. Improving the process measure of accurate documentation could help to identify implementation barriers.

CONCLUSION

 Performing DCC in preterm neonates was feasible and beneficial without increasing admission hypothermia.

KEY POINTS

· Thermoregulation-focused DCC protocol was implemented to increase DCC while maintaining normothermia.. · DCC rate increased from 20 to 57% while admission normothermia rate remained the same.. · DCC practice on preterm neonates is safe and feasible while maintaining normothermia..

[A cross-sectional survey of delivery room transitional care management for very/extremely preterm infants in 24 hospitals in Shenzhen City]

OBJECTIVES

To investigate the current status of delivery room transitional care management for very/extremely preterm infants in Shenzhen City.

METHODS

A cross-sectional survey was conducted in November 2022, involving 24 tertiary hospitals participating in the Shenzhen Neonatal Data Network. The survey assessed the implementation of transitional care management in the delivery room, including prenatal preparation, delivery room resuscitation, and post-resuscitation management in the neonatal intensive care unit. Very/extremely preterm infants were divided into four groups based on gestational age: <26 weeks, 26-28+6 weeks, 29-30+6 weeks, and 31-31+6 weeks. Descriptive analysis was performed on the results.

RESULTS

A total of 140 very/extremely preterm infants were included, with 10 cases in the <26 weeks group, 45 cases in the 26-28+6 weeks group, 49 cases in the 29-30+6 weeks group, and 36 cases in the 31-31+6 weeks group. Among these infants, 99 (70.7%) received prenatal counseling, predominantly provided by obstetricians (79.8%). The main personnel involved in resuscitation during delivery were midwives (96.4%) and neonatal resident physicians (62.1%). Delayed cord clamping was performed in 52 cases (37.1%), with an average delay time of (45±17) seconds. Postnatal radiant warmer was used in 137 cases (97.9%) for thermoregulation. Positive pressure ventilation was required in 110 cases (78.6%), with 67 cases (60.9%) using T-piece resuscitators and 42 cases (38.2%) using a blended oxygen device. Blood oxygen saturation was monitored during resuscitation in 119 cases (85.0%). The median time from initiating transitional care measures to closing the incubator door was 87 minutes.

CONCLUSIONS

The implementation of delivery room transitional care management for very/extremely preterm infants in the hospitals participating in the Shenzhen Neonatal Data Network shows varying degrees of deviation from the corresponding expert consensus in China. It is necessary to bridge the gap through continuous quality improvement and multicenter collaboration to improve the quality of the transitional care management and outcomes in very/extremely preterm infants.

Umbilical Cord Milking Versus Delayed Cord Clamping in Infants 28 to 32 Weeks: A Randomized Trial

OBJECTIVES

To determine whether rate of severe intraventricular hemorrhage (IVH) or death among preterm infants receiving placental transfusion with UCM is noninferior to delayed cord clamping (DCC).

METHODS

Noninferiority randomized controlled trial comparing UCM versus DCC in preterm infants born 28 to 32 weeks recruited between June 2017 through September 2022 from 19 university and private medical centers in 4 countries. The primary outcome was Grade III/IV IVH or death evaluated at a 1% noninferiority margin.

RESULTS

Among 1019 infants (UCM n = 511 and DCC n = 508), all completed the trial from birth through initial hospitalization (mean gestational age 31 weeks, 44% female). For the primary outcome, 7 of 511 (1.4%) infants randomized to UCM developed severe IVH or died compared to 7 of 508 (1.4%) infants randomized to DCC (rate difference 0.01%, 95% confidence interval: (-1.4% to 1.4%), P = .99).

CONCLUSIONS

In this randomized controlled trial of UCM versus DCC among preterm infants born between 28 and 32 weeks' gestation, there was no difference in the rates of severe IVH or death. UCM may be a safe alternative to DCC in premature infants born at 28 to 32 weeks who require resuscitation.

Knowledge gaps in optimal umbilical cord management at birth

In 2014 the World Health Organisation recommended providing placental blood to all newborn infants by waiting for at least one minute before clamping the umbilical cord. Mounting evidence supports providing a placental transfusion at the time of birth for all infants. The optimal time before clamping and cutting the umbilical cord is still not yet known, and debate exists around other cord management issues. The newborn's transition phase from intra- to extra-uterine life and the effects of blood volume on the many necessary adaptations are understudied. How best to support these adaptations guides our suggested research questions. Parents' perceptions of enrolling their unborn infant into a study play important parts in the conduct of such trials. This article aims to address these topics and suggest research questions for further studies.

Umbilical cord management - the first opportunity to improve healthcare disparities

This review focuses on iron deficiency and iron deficiency anemia in women and children in the United States. These are common, fixable problems that disproportionally affect minority populations. There are many opportunities for successful screening and management. The knowledge and awareness for identification and treatment of our populations' commonest deficiency is crucial.

Integrating Implementation Science with Quality Improvement to Improve Perinatal Outcomes

Implementation science is an interdisciplinary field that seeks to contribute generalizable knowledge that can improve the translation of clinical evidence in routine care. To promote the integration of implementation science approaches with health care quality improvement, the authors offer a framework that links the Model for Improvement with implementation strategies and methods. Perinatal quality improvement teams can leverage the robust frameworks of implementation science to diagnose implementation barriers, select implementation strategies, and assess the strategies' contribution to improving care. Partnerships between implementation scientists and quality improvement teams could accelerate efforts by both groups to achieve measurable improvements in care.

Midwifery and nursing: Considerations on cord management at birth

Mounting evidence overwhelmingly supports the practice of the return of an infant's placental blood volume at the time of birth. Waiting just a few minutes before clamping the umbilical cord can provide health benefits to infants of all gestational ages. Despite the robust evidence, uptake of delayed cord clamping (DCC) into mainstream obstetrical practice is moving slowly. The practice of DCC is influenced by various factors that include the setting in which the birth takes place, the use of evidence-informed guidelines and other influences that facilitate or hinder the practice of DCC. Through communication, collaboration, and unique disciplinary perspectives, midwives and nurses work with other members of their respective care team to develop strategies for best practice to improve an infant's well-being through optimal cord management. Midwifery has been practiced for centuries throughout the world and midwives have supported DCC since the beginning of recorded history. An important tenet of midwifery philosophy is watchful waiting and non-intervention in normal processes. Nurses are vital to care of birthing families in- and out-of-hospitals as well as in prenatal and postpartum ambulatory care. Nurses and midwives are positioned to be involved in the process of adapting to the mounting evidence for DCC. Strategies to increase better utilization of the practice of DCC have been proposed. For all, teamwork and collaboration among disciplines participating in maternity care are essential for adapting to the new evidence. Involving midwives and nurses as partners in an interdisciplinary approach to plan, implement and sustain DCC at birth increases success.

Evaluating the evidence behind umbilical cord clamping practices in at-risk neonatal populations

Umbilical cord clamping practices impact nearly 140 million births each year. Current evidence has led professional organizations to recommend delayed cord clamping (DCC), as opposed to early cord clamping (ECC), as the standard of care in uncomplicated term and preterm deliveries. However, variability remains in cord management practices for maternal-infant dyads at higher risk of complications. This review examines the current state of evidence on the outcomes of at-risk infant populations receiving differing umbilical cord management strategies. Review of contemporary literature demonstrates members of high-risk neonatal groups, including those affected by small for gestational age (SGA) classification, intrauterine growth restriction (IUGR), maternal diabetes, and Rh-isoimmunization, are frequently excluded from participation in clinical trials of cord clamping strategies. Furthermore, when these populations are included, outcomes are often underreported. Consequently, evidence regarding optimal umbilical cord management in at-risk groups is limited, and further research is needed to guide best clinical practice.

Integrated review of the knowledge, attitudes, and practices of maternity health care professionals concerning umbilical cord clamping

BACKGROUND

Umbilical cord clamp timing has implications for newborn health, which include increased iron stores up to 6 months of age. National and International cord clamping guidelines differ as do health professionals' practices. The rationale for differences in cord clamping practice is unclear.

AIMS AND OBJECTIVE

Studies on the knowledge, attitudes, and practices of maternity health care professionals about cord clamp timing were synthesized. Similarities and differences between professional groups and understanding of the optimal timing of cord clamp timing for term newborns were compared.

METHODS

An integrative review was undertaken. PubMed, Scopus, MIDIRS, CINAHL, and Google Scholar were searched. Publication date limits were set between January 2007 and December 2020. Quality appraisal was undertaken using the Critical Appraisal Skills Program (CASP) tools.

RESULTS

Eighteen studies met inclusion criteria, as they included primary research studies that investigated maternity health care professionals' knowledge, attitudes, and practices about umbilical cord clamping, and were written in English. Four main subject areas were identified: a) knowledge of optimal cord clamp timing; b) attitudes and perceptions of early vs deferred cord clamping; c) cord clamping practice; and d) rationale for cord clamping practice.

CONCLUSIONS

Different attitudes and practices were identified between midwifery and medical professionals in relation to cord clamp timing together with health professional knowledge and practice gaps pertaining to optimal cord clamp timing. Contemporary evidence should inform guidelines for clinical practice and be embedded into maternity health professional curricula and professional development programs.

Delayed cord clamping practice at birth: A narrative review of literature

BACKGROUND

Anaemia in infants is a major public health concern particularly in low and middle-income countries. Delayed cord clamping (DCC) has been advocated as a strategy to decrease iron deficiency anaemia in infants because of the benefits that come with placental transfusion. Despite the documented benefits of delayed cord clamping in preventing anaemia the current practices of delayed cord clamping by midwives and obstetricians across countries and in different contexts is unclear. This narrative review assesses the literature on delayed cord clamping practices published from 2013 to February 2022, in order to examine current practice in birth units globally, and with a focus in low and middle-income countries (LMICs).

METHOD

A search of four bibliographic databases Medline, Scopus (Elsevier), ProQuest, CINAHL and two network and search engines, Wiley and Google Scholar, was undertaken from 2013 to February 2022 using key terms related to delayed cord clamping and immediate cord clamping. A snowball method as well as backward and forward reference checking was also undertaken.

RESULTS

The search strategy identified 10 studies on umbilical cord clamping practices by midwives and obstetricians. Only two studies were conducted in low and middle-income countries.

CONCLUSION

Despite the potential benefits of DCC in reducing anaemia, particularly in low and middle-income countries where the burden of anaemia is a public health concern, there is a paucity of literature on current DCC practices by obstetricians and midwives. Research to establish current DCC practices in these countries is needed to address this gap in the literature.

A Survey on Current Practices of Umbilical Cord Clamping in Malaysia

Background

Delayed cord clamping (DCC) has been demonstrated to have significant benefits in reducing the incidence of intraventricular hemorrhage, blood transfusion and neonatal mortality in preterm neonates and improving hemodynamic and long-term neurodevelopment among term infants. There is no clear guideline on umbilical cord clamping (UCC) practices in Malaysia.

Objective

The aim of this survey was to assess the knowledge and practice of DCC among obstetric doctors and midwives in Malaysia, and pediatric colleagues who witness the delivery.

Method

This is a cross-sectional survey conducted in childbirth facilities in Malaysia from October 2020 to January 2021. A convenient snowball sampling was adopted. A validated questionnaire was disseminated to practicing obstetric and pediatric doctors and midwives electronically via email and WhatsApp using Google Form. The data were analyzed using descriptive and analytical statistics.

Results

A total of 327 respondents completed the questionnaires, comprising 206 obstetric doctors, 72 pediatric doctors and 49 midwives. The majority of respondents were specialists or higher in rank (53.2%). Only 29% reported the existence of guidelines on UCC in their place of work. Midwives (P = 0.003) and staff of lower ranks and level of education (P < 0.001) appeared to be more aware of the existence of a UCC guideline. Most respondents had positive knowledge of DCC for both term and preterm neonates. A large proportion (82%) of respondents agreed that DCC helped increase neonatal iron stores, and was good for both preterm (70.7%) and term (76.2%) neonates not requiring positive pressure ventilation. Doctors, specialists, those who are 40 years old and above, and those who have been in service for at least 10 years were found to have better knowledge regarding DCC (P < 0.05).

Conclusion

The awareness and practice of obstetric, pediatric and midwifery staff of guidelines on UCC were less than satisfactory. Even though most respondents have good knowledge and positive perception regarding benefits of DCC, these were not translated into their routine practice. Hence, a national guideline emphasizing the benefits of DCC should be made available in all childbirth facilities.

Epidemiological Investigation on the Current Practice of Umbilical Cord Clamping in China

OBJECTIVE

Despite known benefits, the timing of and method used for umbilical cord clamping (UCC) in neonates remain controversial in China, as well as internationally. The objective of this study was to assess knowledge, attitudes, and practice of UCC amongst health care providers in China, as recommended by medical professional organizations.

STUDY DESIGN

A web-based questionnaire on cord clamping practices was administered to midwives, obstetricians, and neonatologists in 126 hospitals from 16 provinces. The provinces were selected from seven different regions of China.

RESULTS

A total of 5,005 (60.5% of eligible respondents) health care providers returned completed questionnaires. The awareness rates for immediate cord clamping (ICC) and delayed cord clamping (DCC) were over 85%, but the implementation rate for DCC was relatively low (ICC 58.3% vs. DCC 41.6%). Most neonates were placed below the introitus (92.8%) during cord clamping and this correlated with the route of delivery. The choice of UCC was impelled by different factors. Benefits for neonates influenced the choice of ICC (50%) and promoting a larger blood volume to stabilize systemic circulation influenced the choice of DCC (92.3%). Majority (91.5%) of respondents acquiesced that it was necessary to develop national clinical guidelines for UCC.

CONCLUSION

The majority of obstetricians, neonatologists, and midwives who participated in this study had a positive perception of DCC. However, this did not translate to daily practice. The practice of UCC is variable and there are no standard guidelines.

KEY POINTS

· The first large-scale epidemiological investigation of umbilical cord ligation is in China.. · The survey included three commonly used umbilical cord clamping methods.. · The respondents included neonatologists..

Factors associated with umbilical cord clamping in term newborns

OBJECTIVE

To identify factors associated with umbilical cord clamping in term newborns and to compare the recording of clamping time in the medical record with what was observed.

METHOD

Cross-sectional study, with 300 mothers-infants, in a university hospital. Clamping time and medical records were observed, and a structured questionnaire was applied to postpartum women for sociodemographic variables. Bivariate analysis, multivariate Poisson Regression model, and Kappa concordance test were performed.

RESULTS

The percentage of late/optimal clamping observed was 53.7%. The associated factors were skin-to-skin contact in the delivery room (PR = 0.76; 0.61-0.95; p = 0.014), position of the newborn below the vaginal canal (PR = 2.6; CI95%: 1.66-4.07; p < 0.001), position of the newborn at the vaginal level (PR = 2.03; CI95%: 1.5-2.75; p < 0.001), and need for newborn resuscitation in the delivery room (PR = 1.42; CI95%; 1.16-1.73; p = 0.001). Kappa concordance level of the professionals, records compared to the observation was: nurse 0.47, obstetrician 0.59, and pediatrician 0.86.

CONCLUSION

the identification of associated factors and the comparison between recording and observing the clamping time can help in the planning and implementation of improvements for adherence to good practices at birth.

Assessing Implementation of Helping Babies Breathe Program Through Observing Immediate Care of Neonates at Time of Delivery

BACKGROUND

Training in neonatal resuscitation has been shown to reduce deaths related to intrapartum asphyxia. Helping Babies Breathe (HBB) is a simulation-based program focusing on training healthcare providers (HCPs) in immediate neonatal care including stimulation, initiating bag mask ventilation (BMV) in the absence of breathing by 1 min of life, and delayed (30-60 s after birth) umbilical cord clamping (DCC). Data on implementation of HBB posttraining are limited.

OBJECTIVE

To determine time from birth to spontaneous breathing, cord clamping, and initiation of BMV in a setting where the majority of HCPs are HBB trained.

METHODS

Two research nurses observed deliveries conducted in two referral hospitals. Timing included the onset of breathing, cord clamping, and initiation of BMV. Deliveries were grouped according to the mode of delivery.

RESULTS

In total, 496 neonates were observed; 410 (82.7%) neonates cried or had spontaneous breathing (median time 17 s) soon after birth, 25/86 (29%) of neonates not breathing responded to stimulation, 61 (12.3%) neonates required BMV, and 2 (0.4%) neonates required chest compression and/or adrenalin. Neonates delivered by cesarean section (CS) took longer to initiate first breath than those delivered vaginally (median time 19 vs. 14 s; p = 0.009). Complete data were available in 58/61 (95%) neonates receiving BMV, which was initiated in 54/58 (93%) cases within 60 s of life (the "Golden Minute"). Median time to cord clamping was 74 s, with 414 (83.5%) and 313 (63.0%) having cord clamped at ≥ 30 and ≥ 60 s, respectively. Factors associated with BMV were CS delivery [odds ratio (OR) 29.9; 95% CI 3.37-229], low birth weight (LBW) (birthweight < 2,500 g) (OR 2.47; 95% CI 1.93-5.91), and 1 min Apgar score < 7 (OR 149; 95% CI 49.3-5,021). DCC (≥ 60 s) was less likely following CS delivery (OR 0.14; 95% CI 0.02-0.99) and being LBW (OR 0.43; 95% CI 0.24-0.77).

CONCLUSION

Approximately 83% of neonates initiated spontaneous breathing soon after birth and 29% of neonates not breathing responded to physical stimulation. BMV was initiated within the Golden Minute in most neonates, but under two-thirds had DCC (≥60 s). HBB implementation followed guidelines, suggesting that knowledge and skills taught from HBB are retained and applied by HCP.

Behaviors and Attitudes of Obstetricians in Turkey Related to Cord Clamping, Cord Milking, and Skin-To-Skin Contact

Objective This study was planned to evaluate obstetricians' practices of umbilical cord clamping, milking, and skin-to-skin contact applications and to determine the related variables. Material and methods A total of 522 obstetricians participated in the study. Participants were reached via the internet and a 15-item questionnaire was applied about umbilical cord clamping, cord milking, and skin-to-skin contact. Mann-Whitney U test and Student's t-test were used for continuous data and Chi-square test or Fisher's exact test for categorical data in determining the difference between groups. For the multivariate analysis, the possible factors identified with univariate analyses were entered into the logistic regression analysis to determine further independent predictors of delayed clamping. Statistical analysis was performed using the SPSS software (version 20, IBM Corp, Armonk, USA). Results It was determined that 234 (44.8%) of the participants clamped the umbilical cord early whereas 288 (55.2%) clamped it late. It was found that the delayed clamping rates of physicians working in public hospitals were significantly lower than those working in private (p<0.001). It was observed that 132 of the participants (25.3%) did not milk the cord and 180 (34.5%) of them applied it continuously, and no significant difference was found between physicians working in the public and private sectors (p=0.130). It was observed that 384 (73.6%) physicians applied skin-to-skin contact. In the multivariate regression analysis, it was determined that working status in a private hospital with a 3.6 odds ratio (OR) (95% CI = 2.0-6.3) and a low number of patients examined daily with a 1.2 OR (95%CI= 1.0-1.4) were the most important independent factors affecting the choice of delayed clamping. Conclusion It is seen that the most important parameter affecting the birth practices of physicians in our country is the employment status in public or private institutions. The age and professional experience of the physicians who clamp the umbilical cord late were found to be higher. Obstetricians are at the key point in obstetrics practice, and the experience of physicians and the type of institution they work with affect these practices.

Effects of Umbilical Cord Milking on Term Infants Delivered by Cesarean Section

OBJECTIVE

Umbilical cord milking (UCM) is an efficient way to achieve optimal placental transfusion in term infants born by cesarean section (CS). However, it is not frequently performed due to concern for short-term adverse effects of increased blood volume, such as polycythemia and hyperbilirubinemia. The aim of this study is to evaluate the short-term effects of UCM on term infants delivered by CS.

STUDY DESIGN

We conducted a pre- and postimplementation cohort study comparing term infants delivered by CS who received UCM five times (141 infants, UCM group) during a 6-month period (August 1, 2017 to January 31, 2018) to those who received immediate cord clamping (ICC) during the same time period (105 infants, postimplementation ICC) and during a 3-month period (October1, 2016 to December 31, 2016) prior to the implementation of UCM (141 infants, preimplementation ICC).

RESULTS

Mothers were older in UCM group compared with both ICC groups. There were no significant differences in other maternal or neonatal characteristics. Although this study was not powered to detect differences in outcomes, the occurrence of hyperbilirubinemia needing phototherapy, symptomatic polycythemia, NICU admissions, or readmissions for phototherapy was similar between the groups.

CONCLUSION

UCM intervention was not associated with increased incidence of phototherapy or symptomatic polycythemia in term infants delivered by CS.

A Questionnaire Assessing Utilization of Delayed Cord Clamping

OBJECTIVE

 The study aimed to assess the practice of delayed cord clamping (DCC) and the awareness of its benefits for newborns between Obstetric (OB) and neonatal physicians. We examined if provider characteristics including years of experience, level of training, familiarity of the American College of Obstetricians and Gynecologists (ACOG)/American Academy of Pediatrics (AAP) recommendations, institutional policy, and the racial and ethnic background of patient population were associated with implementation of DCC.

STUDY DESIGN

 This research is a cross-sectional online questionnaire study.

RESULTS

 975 questionnaires were returned. Overall, the awareness of ACOG versus AAP recommendations was 94 versus 86% (p < 0.01). 86 versus 78% of OB and neonatal physicians practiced or witnessed DCC >50% of the time, respectively (p < 0.01). An equal number of OB and neonatal physicians believed in the benefits to newborns of DCC. Physicians with >10 years of practice were less likely to acknowledge DCC benefits. Physicians with a majority of non-White patients were less likely to practice/witness DCC (p < 0.05).

CONCLUSION

 There continues to be room for improvement in the practice of DCC. Institutional policies and awareness of ACOG/AAP recommendations impact the understanding of the benefits of DCC and the likelihood of the practice. There is a significant difference in the practice of DCC among patients with different racial backgrounds. Hospital leadership may consider investing in the education and implementation of updated guidelines to ensure DCC is routinely practiced.

KEY POINTS

· Knowledge of AAP/ACOG and institutional policies improved the practice of DCC.. · There is racial disparity in the practice of DCC.. · Physicians in practice for >10 years were less likely to know the benefits of DCC to full-term neonates..

Short-term efficacy of umbilical cord milking in preterm infants: systematic review and meta-analysis

BACKGROUND

To systematically evaluate short-term efficacy of UCM versus other interventions in preterm infants.

METHODS

Six engines were searched until February 2020 for randomized controlled trials (RCTs) assessing UCM versus immediate cord clamping (ICC), delayed cord clamping (DCC), or no intervention. Primary outcomes were overall mortality, intraventricular hemorrhage (IVH), and patent ductus arteriosus (PDA); secondary outcomes were need for blood transfusion, mean blood pressure (MBP), serum hemoglobin (Hb), and ferritin levels. Random-effects meta-analyses were used.

RESULTS

Fourteen RCTs (n = 1708) were included. In comparison to ICC, UCM did not decrease mortality (RR 0.5, 95% CI 0.2-1.1), IVH (RR 0.7, 95% CI 0.5-1.0), or PDA (RR 1.0, 95% CI 0.7-1.5). However, UCM reduced need of blood transfusion (RR 0.5, 95% CI 0.3-0.9) and increased MBP (MD 2.5 mm Hg, 95% CI 0.5-4.5), Hb (MD 1.2 g/dL, 95% CI 0.8-1.6), and ferritin (MD 151.4 ng/dL, 95% CI 59.5-243.3). In comparison to DCC, UCM did not reduce mortality, IVH, PDA, or need of blood transfusion but increased MBP (MD 3.7, 95% CI 0.6-6.9) and Hb (MD 0.3, 95% CI -0.2-0.8). Only two RCTs had high risk of bias.

CONCLUSIONS

UCM did not decrease short-term clinical outcomes in comparison to ICC or DCC in preterm infants. Intermediate outcomes improved significantly with UCM.

IMPACT

In 14 randomized controlled trials (RCTs), umbilical cord milking (UCM) did not reduce mortality, intraventricular hemorrhage, or patent ductus arteriosus compared to immediate (ICC) or delayed cord clamping (DCC). UCM improved mean blood pressure and hemoglobin levels compared to ICC or DCC. In comparison to ICC, UCM reduced the need for blood transfusion. We updated searches until February 2020, stratified by type of control, and performed subgroup analyses. There was low quality of evidence about clinical efficacy of UCM. Most of RCTs had low risk of bias. UCM cannot be recommended as standard of care for preterm infants.

Transfusion in Neonatal Patients: Review of Evidence-Based Guidelines

Transfusion of red blood cells, platelets, and fresh frozen plasma in neonatal patients has not been well characterized in the literature, with guidelines varying greatly between institutions. However, anemia and thrombocytopenia are highly prevalent, especially in preterm neonates. When transfusing a neonatal patient, clinicians must take into consideration physiologic differences, gestational and postnatal age, congenital disorders, and maternal factors while weighing the risks and benefits of transfusion. This review of existing literature summarizes current evidence-based neonatal transfusion guidelines and highlights areas of current ongoing research and those in need of future studies.

Variations in umbilical cord clamping practices in the United States: a national survey of neonatologists

OBJECTIVE

Since the first publication of the American College of Obstetricians and Gynecologists committee opinion in 2012, and following the update in 2017, multiple institutions in the United States (US) adopted the practice of delayed cord clamping (DCC) and/or umbilical cord milking (UCM) in preterm and term infants. However, there have been variations reported in practices with regard to method of placental transfusion, timing of cord clamping and gestational age thresholds. Furthermore, the optimal cord clamping practice in situations of depressed infants needing resuscitation or in higher-risk delivery situations, such as placental abruption, intrauterine growth restriction, multiple gestation, chorioamnionitis, maternal human immunodeficiency virus syndrome/hepatitis or maternal general anesthesia is often debated. An evaluation of these variations and exploration of associated factors was needed to optimally target opportunities for improvement and streamline research activities. The objective of this survey, specifically aimed at neonatologists working in the US was to identify and describe current cord clamping practices and evaluate factors associated with variations.

STUDY DESIGN

The survey was distributed electronically to the US neonatologists in August 2019 with a reminder email sent in October 2019. Clinicians were primarily identified from Perinatal Section of AAP, with reminders also sent through various organizations including California Association of Neonatologists, Pediatrix and Envision national groups. Descriptive variables of interest included years of experience practicing neonatology, affiliation with a teaching institution, level of the neonatal intensive care unit (NICU) and practicing region of the US. Questions on variations in cord management practices included information about center specific guideline/protocol, cord clamping practices, gestational age threshold of placental transfusion, performance of UCM and practice in higher-risk delivery situations.

RESULTS

The response rate was 14.8%. Among 517 neonatologists whom responded, majority (85.5%) of the practices had a guideline and performed (81.7%) DCC in all gestational ages. The cord clamping practice was predominantly DCC and it was categorized as reporting clamping times <60 s in 46.6% and ≥60 s in 48.7% of responses. A significant association was detected between time of delay in cord clamping and region of practice. The Northeast region was more likely to clamp the cord in <60 s than other regions in the US. More than half of the providers responded not performing any UCM (57.3%) in their practice. Significant associations were detected between performance of UCM and all queried demographic variables independently. Clinicians with >20 years of experience were more likely from institutions performing UCM compared to the providers with fewer years of experience. However, teaching hospitals were less likely to perform UCM compared to non-teaching hospitals. Similarly, practices with level IV NICUs were less likely to perform UCM compared to practices with level III units. Hospitals in the Midwest region of US were less likely to perform UCM compared to hospitals in the Western region. Significant variations were also noticed for not providing placental transfusion in higher-risk deliveries. Demographic and professional factors were noted to be associated with these differences.

CONCLUSION

Although the majority of practices have a guideline/protocol and are performing DCC in all gestational ages, there are variations noted with regard to timing, method, and performance in higher-risk deliveries. Demographic and professional factors play an important role in these variations. Future research needs to focus on the modifiable factors to optimize the procedure and impact of DCC.

A Comparison of Strategies for Managing the Umbilical Cord at Birth in Preterm Infants

OBJECTIVE

To evaluate the rates of practice, and the associations between different cord management strategies at birth (delayed cord clamping [DCC], umbilical cord milking [UCM], and early cord clamping [ECC]) and mortality or major morbidity, rates of blood transfusion, and peak serum bilirubin in a large national cohort of very preterm infants.

STUDY DESIGN

We retrospectively studied preterm infants <33 weeks of gestation admitted to the Canadian Neonatal Network between January 2015 and December 2017. Patients who received ECC (<30 seconds), UCM, or DCC (≥30 seconds) were compared. Multiple generalized linear/quantile logistic regression models were used.

RESULTS

Of 12 749 admitted infants, 9729 were included; 4916 (50.5%) received ECC, 394 (4.1%) UCM, and 4419 (45.4%) DCC. After adjustment for potential confounders identified between groups in univariate analyses, the odds of mortality or major morbidity were higher in the ECC group when compared with UCM group (aOR, 1.18; 95% CI, 1.03-1.35). Mortality and intraventricular hemorrhage were associated with ECC as compared with DCC (aOR, 1.6 [95% CI, 1.22-2.1] and aOR, 1.29 [95% CI, 1.19-1.41], respectively). The odds of severe intraventricular hemorrhage were higher with UCM compared with DCC (aOR, 1.38; 95% CI, 1.05-1.81). Rates of blood transfusion were higher with ECC compared with UCM and DCC (aOR, 1.67 [95% CI, 1.31-2.14] and aOR, 1.68 [95% CI, 1.35-2.09], respectively), although peak serum bilirubin levels were not significantly different.

CONCLUSIONS

Both DCC and UCM were associated with better short-term outcomes than ECC; however, the odds of severe intraventricular hemorrhage were higher with UCM compared with DCC.

Randomized Study of Delayed Cord Clamping of 30 to 60 Seconds in the Larger Infant Born Preterm

In a randomized study of infants born preterm (gestational age 28-34 6/7 weeks), we evaluated delayed cord clamping for 30 (n = 50) vs 60 (n = 55) seconds. The primary outcome of initial hematocrit differed by 2.8% (P = .006), being greater with 60 seconds. There were no differences in secondary outcomes and no adverse consequences between groups. These findings should serve as a stimulus to many centers that are reluctant to implement delayed cord clamping in this targeted larger premature population.

Maternity health professionals' perspectives of cord clamp timing, cord blood banking and cord blood donation: a qualitative study

Background

Parents today have several options for the management of their infant’s cord blood during the third stage of labour. Parents can choose to have their infant’s cord clamped early or to have deferred cord clamping. If the cord is clamped early, cord blood can be collected for private cord blood banking or public cord blood donation for use later if needed. If cord clamping is deferred, the placental blood physiologically transfuses to the neonate and there are physiological advantages to this. These benefits include a smoother cardiovascular transition and increased haemoglobin levels while not interfering with the practice of collecting cord blood for gases if needed. The aim of this study is to explore Australian maternity health professionals’ perspectives towards cord clamp timing, cord blood banking and cord blood donation.

Methods

Fourteen maternity health professionals (midwives and obstetricians) from both private and public practice settings in Australia participated in semi-structured interviews either in person or by telephone. Interviews were transcribed and data analysed using thematic analysis.

Results

Overall there was strong support for deferred cord clamping, and this was seen as important and routinely discussed with parents as part of antenatal care. However, support did not extend to the options of cord blood banking and donation and to routinely informing parents of these options even when these were available at their birthing location.

Conclusion

Formalised education for maternity health professionals is needed about the benefits and implications of cord blood banking and cord blood donation so that they have the confidence to openly discuss all options of cord clamp timing, cord blood banking and cord blood donation to facilitate informed decision-making by parents.

Umbilical Cord Practices of Members of the American College of Nurse-Midwives

INTRODUCTION

Mercer et al surveyed members of the American College of Nurse-Midwives (ACNM) about their umbilical cord clamping practices in 2000. Over the last 20 years, a significant body of research supporting delayed cord clamping (DCC) has been published. The purpose of this study was to learn how midwives today manage the umbilical cord at birth.

METHODS

To better understand the current practices of midwives, in 2017, a national online survey of ACNM members was conducted. A total of 24 questions were asked about DCC, cord milking, specific clinical circumstances, and the presence of policies or guidelines.

RESULTS

A total of 5306 surveys were sent with 1106 responses. After applying inclusion criteria, 1050 were available for analysis. Respondents practiced in all settings: home, birth centers, and hospitals. Compared with 2000, a 46% increase in the practice of DCC was identified. In this study, 98% of the participants reported facilitating DCC for full-term vaginal births as compared with 67% in 2000. In addition, 25% practiced DCC for near-term and 65% for preterm neonates. Cord milking was practiced by 37% of participants. When asked about barriers to practicing DCC, 54% of participants identified time pressures to hand off the newborn as the greatest detriment. It was challenging to practice DCC in situations wherein the newborn needed resuscitation or in breech births. Far fewer midwives practice cord milking compared with DCC.

DISCUSSION

The survey results suggest there has been an increase in the practice of DCC over the last 20 years. Cord milking is not as widely practiced as DCC, and respondents were less likely to be convinced by the evidence for cord milking. This speaks to the opportunity for more education for midwives. There is also a need for clinical guidelines that address umbilical cord management when challenging circumstances arise such as breech birth, shoulder dystocia, and the need for resuscitation.

Variability and associated factors in the management of cord clamping and the milking practice among Spanish obstetric professionals

Clinical practice guides recommend delayed clamping of the umbilical cord. If this is not possible, some authors suggest milking as an alternative. The objective of this study was to determine the variability in professional practice in the management of umbilical cord clamping and milking and to identify factors or circumstances associated with the different methods. An observational cross-sectional study done on 1,045 obstetrics professionals in Spain in 2018. A self-designed questionnaire was administered online. The main variables studied were type of clamping and use of milking. Crude odds ratios (OR) and adjusted odds ratios (ORa) were estimated using binary logistic regression. 92.2% (964) performed delayed clamping. 69.3% (724) clamped the cord when it stopped beating. 83.8% (876) had heard of milking, and 55.9% (584) had never performed it. Professionals over 50 were less likely to perform delayed clamping, with an ORa of 0.24 (95% CI: 0.11–0.52), while midwives were more likely to perform delayed clamping than obstetricians, with an ORa of 14.05 (95% CI: 8.41–23.49). There is clinical variability in the management of umbilical cord clamping and the use of milking in normal births. Part of this variability can be attributed to professional and work environment factors.

Strategies for implementing placental transfusion at birth: A systematic review

BACKGROUND

Enhanced placental transfusion reduces adverse neonatal outcomes, including death. Despite being endorsed by the World Health Organization in 2012, the method has not been adopted widely in practice.

METHODS

We performed a systematic literature search and included quality improvement projects on placental transfusion at birth and studies on barriers to implementation. We extracted information on population, methods of implementation, obstacles to implementation, and strategies to overcome them.

RESULTS

We screened 99 studies out of which 18 were included in the review. The preferred methods of implementation were protocol development (86% of studies) reinforced by targeted education (64% of studies) and multidisciplinary team involvement (43% of studies). Barriers to implementation were mentioned in 12 studies and divided into four categories: general factors such as lack of staff awareness (5 studies) and professional resistance to change (5 studies); obstetrician-specific concerns, including the impact during cesarean (3 studies) and the risk of postpartum hemorrhage (3 studies); pediatrician-specific concerns, including the need for resuscitation (5 studies), risk of jaundice (3 studies), and polycythemia (2 studies); and logistical difficulties. The main strategies to facilitate placental transfusion at birth included effective multidisciplinary team collaboration, protocol development, targeted education, and constructive feedback sessions.

CONCLUSIONS

Placental transfusion implementation requires a multidisciplinary approach, with obstetricians, midwives, nurses, and pediatricians central to adoption of the practice. Understanding the obstacles to implementation informs strategies to increase placental transfusion adoption of practice worldwide. We suggest a stepwise approach to implementation and enhancement of placental transfusion into practice.

Umbilical Cord Milking: A Review

This is a review of umbilical cord milking, a controversial technique where the umbilical cord is squeezed several times before it is clamped an cut. While not physiological or natural for newborns, the question lies as to whether it is useful in certain circumstances, namely the depressed newborn. Here we review the literature and discuss why it could be considered as an alternative for the current practice of delayed cord clamping.
