Neonatal and Maternal Outcomes of Immediately versus Delayed Umbilical Cord Clamping in Full Term Caesarean Delivery

Maternal and neonatal outcomes after delayed vs early cord clamping at cesarean delivery: a systematic review and meta-analysis.

Background: Recent interest has focused on the influence of obstetric anesthesia types on the immediate neonatal and maternal outcome. Aim of the work: The study was intended to assess the immediate neonatal and maternal outcome in relation to the maternal anesthesia type during cesarean section.Patients and methods: the present study included 200 full term neonates whose mothers underwent elective cesarean section (CS). They were grouped according to type of anesthesia given to mothers into group 1: included 100 newborns whose mothers had general anesthesia and group 2: included 100 newborns whose mothers had spinal anesthesia. Each newborn evaluated for short-term outcome including Apgar score, need for NICU admission and blood gas analysis. Mothers assessed for postoperative outcome. Results: No significant differences were discovered between the types of anesthesia used in regard to the general maternal characteristics. Neonatal outcomes on the other hand showed no significant differences as regard Apgar score (P=0.33) and NICU admission (P= 0.57), PaCO2, HCO3, Na and K; while PH and PaO2 were significantly lower with spinal anesthesia (P= 0.02 and 0.008 respectively). Additionally, spinal anesthesia was associated with rapid recovery of bowel and less need for postoperative analgesia. Conclusion: The type of anesthesia used in mothers undergoing full term elective cesarean deliveries does not seem to affect the immediate neonatal outcome. Both may be safely used in full term elective cesarean deliveries. However, spinal anesthesia had the advantage of lower need for postoperative analgesia with rapid recovery of bowel

Policies for timing of cord clamping vary, with early cord clamping generally carried out in the first 60 seconds after birth, whereas later cord clamping usually involves clamping the umbilical cord more than one minute after the birth or when cord pulsation has ceased. The benefits and potential harms of each policy are debated. To determine the effects of early cord clamping compared with late cord clamping after birth on maternal and neonatal outcomes We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (13 February 2013). Randomised controlled trials comparing early and late cord clamping. Two review authors independently assessed trial eligibility and quality and extracted data. We included 15 trials involving a total of 3911 women and infant pairs. We judged the trials to have an overall moderate risk of bias. Maternal outcomes: No studies in this review reported on maternal death or on severe maternal morbidity. There were no significant differences between early versus late cord clamping groups for the primary outcome of severe postpartum haemorrhage (risk ratio (RR) 1.04, 95% confidence interval (CI) 0.65 to 1.65; five trials with data for 2066 women with a late clamping event rate (LCER) of ~3.5%, I(2) 0%) or for postpartum haemorrhage of 500 mL or more (RR 1.17 95% CI 0.94 to 1.44; five trials, 2260 women with a LCER of ~12%, I(2) 0%). There were no significant differences between subgroups depending on the use of uterotonic drugs. Mean blood loss was reported in only two trials with data for 1345 women, with no significant differences seen between groups; or for maternal haemoglobin values (mean difference (MD) -0.12 g/dL; 95% CI -0.30 to 0.06, I(2) 0%) at 24 to 72 hours after the birth in three trials. Neonatal outcomes: There were no significant differences between early and late clamping for the primary outcome of neonatal mortality (RR 0.37, 95% CI 0.04 to 3.41, two trials, 381 infants with a LCER of ~1%), or for most other neonatal morbidity outcomes, such as Apgar score less than seven at five minutes or admission to the special care nursery or neonatal intensive care unit. Mean birthweight was significantly higher in the late, compared with early, cord clamping (101 g increase 95% CI 45 to 157, random-effects model, 12 trials, 3139 infants, I(2) 62%). Fewer infants in the early cord clamping group required phototherapy for jaundice than in the late cord clamping group (RR 0.62, 95% CI 0.41 to 0.96, data from seven trials, 2324 infants with a LCER of 4.36%, I(2) 0%). Haemoglobin concentration in infants at 24 to 48 hours was significantly lower in the early cord clamping group (MD -1.49 g/dL, 95% CI -1.78 to -1.21; 884 infants, I(2) 59%). This difference in haemoglobin concentration was not seen at subsequent assessments. However, improvement in iron stores appeared to persist, with infants in the early cord clamping over twice as likely to be iron deficient at three to six months compared with infants whose cord clamping was delayed (RR 2.65 95% CI 1.04 to 6.73, five trials, 1152 infants, I(2) 82%). In the only trial to report longer-term neurodevelopmental outcomes so far, no overall differences between early and late clamping were seen for Ages and Stages Questionnaire scores. A more liberal approach to delaying clamping of the umbilical cord in healthy term infants appears to be warranted, particularly in light of growing evidence that delayed cord clamping increases early haemoglobin concentrations and iron stores in infants. Delayed cord clamping is likely to be beneficial as long as access to treatment for jaundice requiring phototherapy is available.

BACKGROUND Corona virus disease 2019 (COVID 19) outbreak have evolved rapidly throughout the world. The knowledge on severe acute respiratory disease-corona virus-2 (SARS-CoV-2) infection in pregnant women and newborn is incomplete. Understanding the impact of COVID 19 in pregnancy in terms of morbidity mortality, perinatal and neonatal outcome is essential to propose a strategy for the management of pregnant women with COVID 19 infection. METHOD It is a prospective study of all pregnant women who have delivered in the period of April 2020 to December 2020 at Government T.D. Medical College, Alappuzha. In this study, the mode of delivery, neonatal outcome, maternal mortality, morbidity were evaluated. The outcome of pregnancies includes vaginal delivery, caesarean delivery, vacuum delivery and intrauterine fetal demise. RESULTS A total of 265 pregnant women infected with COVID 19 delivered during the period. Out of these, 49.4 % was full term caesarean delivery, 3.8 % was preterm caesarean delivery, 39.3 % was full term vaginal delivery and 4.9 % was preterm vaginal delivery. Moreover, 1.1 % of the total pregnant women had intrauterine fetal demise on admission. Among 265 new-borns, 2.3 % babies became COVID 19 positive, of this, 83.3 % were mothers who delivered within 7 days of COVID 19 infection. 0.75 % needed resuscitative emergency caesarean delivery for COVID 19 pneumonia. 0.38 % maternal mortality occurred during the period due to COVID 19 infection. CONCLUSIONS Obstetric outcome in most COVID 19 infected term pregnant patients is comparable to non-COVID 19 pregnant women except for a higher incidence of caesarean delivery. Most of the neonates who became positive were born to mothers delivered within 7 days of COVID 19 infection. Severe morbidity among COVID 19 pregnant women were seen only in a small proportion complicated by COVID 19 pneumonia, who required ventilator support.

Birth at early term (37+0-38+6 completed gestational weeks [GW] and additional days) is associated with adverse neonatal outcomes compared with waiting to ≥39 GW. Most studies report outcomes after elective cesarean section or a mix of all modes of births; it is unclear whether these adverse outcomes apply to early-term babies born after induction of labor (IOL). We aimed to determine, in women with a non-urgent induction indication (elective/planned >48 h in advance), if IOL at early and late term was associated with adverse neonatal and maternal outcomes compared with IOL at full term. An observational cohort study as a secondary analysis of a multicenter randomized controlled trial of 1087 New Zealand women with a planned IOL ≥37+0 GW. Multivariable logistic regression was used to analyze neonatal and maternal outcomes in relation to gestational age; 37+0-38+6 (early term), 39+0-40+6 (full term) and ≥41+0 (late term) GW. Neonatal outcome analyses were adjusted for sex, birthweight, mode of birth and induction indication, and maternal outcome analyses for parity, age, body mass index and induction method. The primary neonatal outcome was admission to neonatal intensive care unit (NICU) for >4 hours; the primary maternal outcome was cesarean section. Among the 1087 participants, 266 had IOL at early term, 480 at full term, and 341 at late term. Babies born following IOL at early term had increased odds for NICU admission for >4 hours (adjusted odds ratio [aOR] 2.16, 95% confidence intervals (CI) 1.16-4.05), compared with full term. Women having IOL at early term had no difference in emergency cesarean rates but had an increased need for a second induction method (aOR 1.70, 95% CI 1.15-2.51) and spent 4 h longer from start of IOL to birth (Hodges-Lehmann estimator 4.10, 95% CI 1.33-6.95) compared with those with IOL at full term. IOL for a non-urgent indication at early term was associated with adverse neonatal and maternal outcomes and no benefits compared with IOL at full term. These findings support international guidelines to avoid IOL before 39 GW unless there is an evidence-based indication for earlier planned birth and will help inform women and clinicians in their decision-making about timing of IOL.

To evaluate the risks of neonatal and maternal adverse outcomes in individuals with low-risk, singleton, term breech presentation associated with vaginal compared with cesarean delivery in a contemporary cohort in the United States. We conducted a propensity score analysis to evaluate adverse neonatal and maternal outcomes associated with mode of delivery among individuals with breech presentation at term. We used U.S. vital statistics data, which included information on all live births from 2015 to 2020. The eligible cohort was restricted to individuals who delivered a liveborn singleton, nonanomalous neonate at term. The treatment was vaginal or cesarean delivery. Composite neonatal and maternal outcomes were examined using a propensity score analysis to create groups based on mode of delivery with a 5-to-1 match of cesarean to vaginal deliveries. The composite neonatal outcome included neonatal mortality, 5-minute Apgar score less than 4, seizures or serious neurologic dysfunction, neonatal intensive care unit admission, or assisted ventilation 6 hours or longer. The composite maternal outcome included uterine rupture, maternal transfusion, intensive care unit admission, unplanned hysterectomy, or perineal lacerations. Of 23,118,953 singleton births, 375,500 term, nonanomalous, breech live births were identified. Of these, 5.1% (95% CI, 5.0-5.2; n=19,256) were vaginal deliveries. After propensity score matching, the final cohort comprised 96,095 patients, including 17,558 vaginal deliveries and 78,537 cesarean deliveries. The risks of the composite adverse neonatal outcome were 7.2% in the vaginal delivery group, compared with 6.3% in the cesarean delivery group (risk difference [RD] 1.0; 95% CI, 0.9-1.2; doubly robust odds ratio 1.14; 95% CI, 1.06-1.22). The primary contributor to neonatal morbidity within the vaginal breech cohort was 5-minute Apgar score less than 4 (RD 1.6; 95% CI, 1.4-1.9). Other neonatal outcomes were not different. Neonatal mortality rates were 0.4% (n=67) for vaginal births and 0.1% (n=102) for cesarean births (RD 0.3; 95% CI, 0.2-0.4). The risk of the composite adverse maternal outcome (excluding perineal lacerations) was 0.3% for vaginal births and 0.5% for cesarean breech births (RD -0.4, 95% CI, -0.5 to -0.3). Although term vaginal breech delivery was associated with slightly higher odds of the composite adverse neonatal outcome compared with cesarean delivery, the absolute risk remains low. Short-term maternal outcomes were better for individuals who underwent vaginal delivery compared with cesarean delivery, after exclusion of perineal lacerations.

Association Between Interpregnancy Interval and Adverse Neonatal and Maternal Outcomes Stratified by Gestational Age in Previous Pregnancy in China

To estimate the incidence of gestational diabetes mellitus (GDM) according to The International Association of the Diabetes and Pregnancy Study Groups (IADPSG) criteria and the pregnancy complications in women fulfilling these criteria but who are not considered diabetic according to the Canadian Diabetes Association criteria. We estimated the rate of GDM according to the IADPSG criteria from November 2008 to October 2010. Then, we conducted a chart review to compare maternal and neonatal outcomes between women classified as GDM according to the IADPSG criteria but not by the Canadian Diabetes Association criteria (group 1; n=186) and nondiabetic women according to both criteria (group 2; n=372). Results were expressed as crude (odds ratio [OR]) or adjusted OR and 95% confidence interval (CI). The study has a statistical power of 80% to detect a difference between 16% and 8% in large for gestational age newborns (α level of 0.05; two-tailed). The rate of GDM using the IADPSG criteria was 27.51% (95% CI 25.92-29.11). Group 1 presented similar rates of large-for-gestational-age newborns (9.1% compared with 5.9%, adjusted OR 1.58, 95% CI 0.79-3.13; P=.19), delivery complications (37.1% compared with 30.1%, OR 1.37, 95% CI 0.95-1.98; P=.10), preeclampsia (6.5% compared with 2.7%, adjusted OR 2.40, 95% CI 0.92-6.27; P=.07), prematurity (6.5% compared with 2.7%, OR 1.10, 95% CI 0.53-2.27; P=.85), neonatal complications at delivery (13.4% compared with 9.7%, OR 1.45, 95% CI 0.84-2.49; P=.20), and metabolic complications (10.8% compared with 14.2%, OR 0.73, 95% CI 0.42-1.26; P=.29) compared with group 2. Women classified as nondiabetic by the Canadian Diabetes Association Criteria but considered GDM according to the IADPSG criteria have similar pregnancy outcomes as women without GDM. More randomized studies with cost-effectiveness analyses are needed before implementation of these criteria. II.

Timing of cord clamping in very preterm infants: more evidence is needed

Are increased fetal movements during pregnancy a predictor of neonatal adverse outcomes?

Background: Recent protocol proposed by the World Health Organization to manage the third stage of labour replaced the early cord clamping by deferred cord clamping to induce numerous neonatal benefits. But this practice is still resisted in most of the Arab countries. The aim of this study was to evaluate the effectiveness of deferred versus early umbilical cord clamping on maternal and neonatal outcomes. Methods: A quasi experimental research design was utilized. The study was conducted at labour unit in Damanhour National Medical Institute. Sample: A convenience sample of 150 parturient women undergoing normal vaginal delivery were randomly divided in two groups; deferred cord clamping (n= 75) and early cord clamping (n= 75). Tools: Three tools were used for data collection; 1) Structured interview schedule to collect data about the women' demographic characteristics and reproductive history. 2) Maternal outcomes assessment sheet. 3) Neonatal outcomes assessment sheet to assess the immediate and late neonatal outcomes. Results: There were no statistically significant differences (P > 0.05) between deferred and early cord clamping groups in relation to the maternal risk for post-partum hemorrhage, duration of third stage of labour and the need for manual removal of the placenta. Furthermore, a highly statistically significant differences (p Conclusion: The study concluded that deferred umbilical cord clamping did not increase the risk of maternal post-partum hemorrhage, duration of third stage of labour or the need for manual removal of the placenta. Also, deferred cord clamping significantly increased neonatal hemoglobin, hematocrit, and red blood cells level without serious elevation in the total bilirubin level as it was still in the low intermediate risk or below 75th percentile. Recommendation: Institutionalization of deferred cord clamping in all governmental hospitals and medical educational settings through providing policies, procedures and guidelines regarding this practice. This could significantly improve the intra-natal care for the neonate without harmful consequences for the mother.
