Objective This study aimed to assess risk for fetal acidemia, low Apgar scores, and hypoxic ischemic encephalopathy based on decision-to-incision time interval in the setting of emergency cesarean delivery. Study Design This unplanned secondary analysis of the Maternal–Fetal Medicine Units prospective observational cesarean registry dataset evaluated risk for hypoxic ischemic encephalopathy, umbilical cord pH ≤7.0, and Apgar score ≤4 at 5 minutes based on decision-to-incision time for emergency cesarean deliveries. Cesarean occurring for nonreassuring fetal heart rate monitoring, bleeding previa, nonreassuring antepartum testing, placental abruption, or cord prolapse was classified as emergent. Decision-to-incision time was categorized as <10 minutes, 10 to <20 minutes, 20 to <30 minutes, 30 to <50 minutes, or ≥50 minutes. As secondary outcomes umbilical cord pH ≤7.1, umbilical artery pH ≤7.0, and Apgar score ≤5 at 5 minutes were analyzed. Results Of 5,784 women included in the primary analysis, 12.4% had a decision-to-incision interval ≤10 minutes, 20.2% 11 to 20 minutes, 14.9% 21 to 30 minutes, 18.2% 31 to 50 minutes, and 16.5% >50 minutes. Risk for umbilical cord pH ≤7.0 was highest at ≤10 and 11 to 20 minutes (10.2 and 7.9%, respectively), and lowest at 21 to 30 minutes (3.9%), 31 to 50 minutes (3.9%), and >50 minutes (3.5%) (p < 0.01). Risk for Apgar scores ≤4 at 5 minutes was also higher with decision-to-incision intervals ≤10 and 11 to 20 minutes (4.3 and 4.4%, respectively) compared with intervals of 21 to 30 minutes (1.7%), 31 to 50 minutes (2.1%), and >50 minutes (2.0%) (p < 0.01). Hypoxic ischemic encephalopathy occurred in 1.5 and 1.0% of women with decision-to-incision intervals of ≤10 and 11 to 20 minutes compared with 0.3 and 0.5% for women with decision-to-incision intervals of 21 to 30 minutes and 31 to 50 minutes (p = 0.04). Risk for secondary outcomes was also higher with shorter decision-to-incision intervals. Conclusion Shorter decision-to-incision times were associated with increased risk for adverse outcomes in the setting of emergency cesarean. Key Points

Objectives: To determine relationship between immediate postpartum umbilical cord pH, fetal distress and neonatal outcome Methods: This descriptive cross-sectional study was conducted in the department of Gynaecology, Lady Reading Hospital Peshawar, Pakistan, from January 2019 to July 2019. This study included 27 full-term pregnant women who had abnormal CTG during the active or latent phase of labour. Data were analyzed by IBM SPSS Statistics for Windows, Version 23.0. Results: Out of 27, most patients 13 (48.14%) were in the age group 20-25 years,11 (40.74%) to 26-30 years and 3 (11.11%) belonged to 31-35 years of age group. CTG abnormalities were severe bradycardia, late deccelerations and persistent variable deccelerations with loss of baseline variability. Of all delivered babies, 21 (77%) babies had birth weight<3.5 kg and 6 (22%) had >3.5 kg birth weight. 20 (74.07%) had acidosis (pH <7.2) at the time of birth, of which one had severe hypoxemia and acidosis with pH 6.85. APGAR score at 0 minutes showed a strong positive correlation (r=0.818, p= <0.001) with cord pH, while APGAR at five minutes was also strongly correlated (r= 773, p=<0.001). Of all babies 18(66.66%) with PH less than 7.2 were admitted in NICU while only 2 babies with PH more than 7.2 were admitted. (p value= 0.005). Conclusion: Low umbilical cord pH values of babies born by cesarean section (for fetal distress) are strongly correlated with low APGAR score at birth and higher rates of NICU admission. doi: https://doi.org/10.12669/pjms.36.7.2536 How to cite this:Syed W, Liaqat N, Qazi Q, Yasmeen S.

Abstract Objective To estimate the reliability of the Apgar score (AS) and umbilical cord pH (UCP) as prognostic tools among very low birth weight (VLBW) infants. Study Design Retrospective study based on data of 1237 VLBW neonates born between 1997 and 2013 at one tertiary medical center. For each newborn, a complication score (CS) was calculated based on common complications of prematurity. Results The AS at 1 and 5 minutes correlated well with CS (correlation coefficients -0.47 and -0.52, respectively). No significant correlation was found between UCP and CS (correlation coefficient -0.08). Multi regression analysis revealed that the variables with the greatest prognostic contribution were birth weight, gestational age and prenatal steroid administration (beta values 0.277, 0.251 and 0.087, respectively). Conclusion The AS at 1 and 5 minutes, but not UCP, combined with gestational age, birth weight, and prenatal steroids, can be significant parameters for predicting prognosis among VLBW neonates.

Before And After

SummaryThe authors compared the oxygen consumption in platelets from the umbilical cord blood of 36 healthy newborn infants with that of 27 adult subjects, before and after thrombin addition (1.67 U/ml). Oxygen consumption at rest was 6 mμmol/109/min in adult control platelets and 5.26 in newborn infants. The burst in oxygen consumption after thrombin addition was 26.30 mμmol/109/min in adults and 24.90 in infants. Dinitrophenol did not inhibit the burst of O2 consumption in platelets in 8 out of 10 newborn infants, while the same concentration caused a decrease in 9 out of 10 adult subjects. Deoxyglucose inhibited the burst in O2 consumption in newborn infant and adult platelets by about 50%. KCN at the concentration of 10−4 M completely inhibited basal oxygen consumption but did not completely inhibit the burst after thrombin. At the concentration of 10−3 M, it inhibited both basal O2 consumption and the burst in infants and adult subjects.

Delivery Room Management

Approximately 800,000 newborns die annually due to birth asphyxia. The resuscitation of asphyxiated term newly born infants often occurs unexpected and is challenging for healthcare providers as it demands experience and knowledge in neonatal resuscitation. Current neonatal resuscitation guidelines often focus on resuscitation of extremely and/or very preterm infants; however, the recommendations for asphyxiated term newborn infants differ in some aspects to those for preterm infants (i.e., respiratory support, supplemental oxygen, and temperature management). Since the update of the neonatal resuscitation guidelines in 2015, several studies examining various resuscitation approaches to improve the outcome of asphyxiated infants have been published. In this review, we discuss current recommendations and recent findings and provide an overview of delivery room management of asphyxiated term newborn infants.
