Purpose Our aim was to describe the changes observed by ultrasonography in uterine dimensions during the early puerperium among women who experienced an uncomplicated puerperium. Additionally, the influence of parity, mode of delivery, breastfeeding and birth weight on uterine involution was evaluated. Methods Ninety-one patients underwent an ultrasound examination on days 1 (D1), 2 (D2) and 7 (D7) of the postpartum period. The longitudinal, anteroposterior and transverse uterine diameters were measured, and the uterine volume was calculated by the formula: longitudinal diameter (LD) X anteroposterior diameter (APD) X transverse diameter (TD) X 0.45. The thickness and length of the uterine cavity were also measured. Results The uterine volume and the LD, APD and TD decreased by 44.8%, 20.9%, 11.8% and 20.0% respectively. The uterine cavity thickness was reduced by 23%, and the length of the cavity was reduced by 27.2% on D7. Uterine involution was correlated inversely with parity when the day of the postpartum period was not taken into account (p = 0.01). However, when the uterine involution was correlated to parity separately, with D1, D2 or D3, no correlations were found. A significant difference occurred at D2, when it was found that the uterus had a smaller volume following cesarean section compared with vaginal delivery (p = 0.04). The high birth weight and breastfeeding were significantly related to uterine involution (p ≤ 0.01 and p = 0.04). Conclusion The sonographic evaluation of the uterus in the early puerperium should consider birth weight, breastfeeding and parity, as well as the delivery route on D2, to identify abnormalities related to uterine involution.

Abstract Background The Covid-19 pandemic response is influencing maternal and neonatal health care services especially in developing countries. However, the indirect effects of Covid-19 on pregnancy outcomes remain unknown. The aim of the present study was to compare pregnancy outcomes before and after the beginning of the Covid-19 pandemic in Iran. Methods We performed a retrospective analysis of the medical records of 2,503 pregnant women with singleton pregnancies, admitted to the maternity department of a women’s hospital in Tehran, Iran, during the pre-Covid-19 pandemic (February 19 to April 19, 2019) and the intra-Covid- 19 pandemic (February 19 to April 19, 2020) period. Results We included 2,503 women admitted to the hospital; 1,287 (51.4 %) were admitted before the Covid-19 lockdown and 1,216 (48.6 %) during the Covid-19 lockdown. There were no significant differences in stillbirth rates (p = 0.584) or pregnancy complications (including preeclampsia, pregnancy-induced hypertension and gestational diabetes) (p = 0.115) between pregnant women in the pre- and intra-pandemic periods. However, decreases in preterm births (p = 0.001), and low birth weight (p = 0.005) were observed in the pandemic period compared to the pre-pandemic period. No significant difference in the mode of delivery, and no maternal deaths were observed during the two time periods. Conclusions In our study we observed a decrease in preterm births and low birth weight, no change in stillbirths, and a rise in the admission rates of mothers to the ICU during the initial Covid-19 lockdown period compared to pre-Covid-19 lockdown period. Further research will be needed to devise plan for immediate post-pandemic care and future health care crises.

Background: The transition from a fetus to a newborn is the most complex adaptation that occurs in human experience. This study assessed three physiological parameters viz. temperature (core and peripheral), oxygen saturation and heart rate so as to avoid the delay in normal transitional adaptation.Methods: This cross-sectional observational study was done at Narayana Medical College Hospital, Nellore, Andhra Pradesh, India. A total of 150 neonates born from June 2017 to February 2018 were monitored for heart rate, oxygen saturation, core and peripheral temperature from birth to 60 minutes.Results: Most of the mother’s (45.33%) were aged between 22 to 25 years and the mean age was 23.75±3.64 years. History of consanguineous marriage was noted in 33.33%. The mode of delivery was vaginal in 70.67% of the babies. The mean gestational age was 38.74±1.36 weeks. The birth weight among 62% of the babies was between 2.5 to 3.49 Kgs and mean birth weight was 2.81±0.49 kgs. The meconium stained liquor and requirement of resuscitation was noted in 9.33% and 10.67% respectively.Conclusions: Significant difference was noted with regard to heart rate in babies with active resuscitation, low birth weight (<2.5 kg), meconium stained liquor and warmer care compared to normal babies. There was variation in oxygen saturation in babies who required resuscitation and warmer care, and those who had low birth weight. The mean peripheral and core temperature were different in babies with abdominal care compared to warmer care.

Background: Neonatal hypoglycemia is a common metabolic problem especially in cases like prematurity, sepsis and small gestational age. Episodes of asymptomatic hypoglycemia may occur due to many risk factors. The present study aimed to evaluate the incidence of asymptomatic hypoglycemia in term new born babies weighing more than 2 kg, to study the plasma sugar level at various time points during first 48 hours of life and to study the effect of maternal factors like parity, mode of delivery, glucose infusion during labour, and time since last feed on plasma sugar level.Methods: A hospital based longitudinal study was conducted over a period of one year from April 2005 to March 2006 in Kilpauk Medical College Hospital, Chennai. 400 babies born of consecutive deliveries were included in the study. Their plasma glucose levels were assessed in cord blood, 3 hr, 12 hr and 36 hr of life. Plasma glucose levels were analysed with regards to distribution, variables like parity, mode of delivery, dextrose infusion during labour and time since last feed. The plasma glucose levels were statistically analysed by paired student ‘t’ test, multiple analysis of variance (ANOVA), chi- square test using SPSS (version 7.5) statistical package.Results: The overall incidence of hypoglycemia was seen in 20% of the neonate’s in which 29.7% in small gestational age (SGA) and 16.7% in appropriate gestational age (AGA) babies. A significant (p <0.01) association between hypoglycemia and birth weight was observed. The association between hypoglycemia with parity, mode of delivery, sex of the baby and glucose infusion received by the mother was studied, but no significant association was found. A significant difference in plasma glucose based on birth weight at 3rd hour, 12th hour and 36th hour was observed (p <0.05). None of the infants showed any clinical signs of hypoglycemia.Conclusions: The incidence of hypoglycemia was noted in 20% of the neonates. Low birth weight was considered as risk factor. A significant association was also observed between plasma glucose, mode of delivery and time since last fed.

Abstract Background Preterm birth with its complications is one of the leading causes of perinatal morbidity and mortality, as well as maternal morbidity, especially in low and middle-income countries. Cervical cerclage is a well-established preventive tool in women at high risk of preterm birth; however, subclinical maternal infection might still cause failure of this method. Thus, adding prophylactic antibiotics, namely macrolides, could prevent preterm birth. Patients and methods This was a randomized controlled clinical trial involving two groups of women who underwent vaginal cerclage at Ain Shams University Maternity Hospital. One group received azithromycin 500mg one tablet orally once daily for 3 days every month from 14th week to 34th week gestation, in addition to routine antenatal care; while the other group received usual antenatal care without antibiotic prophylaxis after cerclage. Follow-up was done and we compared the outcomes in each group: gestational age at delivery, birth weight, mode of delivery, maternal complications, and perinatal complications. ClinicalTrials.gov Identifier NCT04278937. Results Gestational age at delivery was significantly higher in the azithromycin group (36.8weeks vs 34.1weeks; P = 0.017), with significant prolongation of gestation in the azithromycin group (23.7weeks vs 21.1weeks; P = 0.005). As regards birth weight, it was significantly higher in the azithromycin group (2932.6gm vs 2401.8gm; P = 0.006); however babies with low birth weight (birth weight &lt;2500gm) were non-significantly less frequent in the azithromycin group (3cases vs 7cases; P = 0.165). There was no significant difference between the two groups as regards other outcomes (miscarriage, stillbirth, neonatal intensive care unit admission, antepartum hemorrhage, postpartum pyrexia, need for blood transfusion). Conclusion Adding azithromycin as antenatal prophylaxis in women undergoing vaginal cerclage prolongs pregnancy and reduces risk of PTB, with slight increase in birth weight. However, there was no clear effect on incidence of low birth weight, or perinatal morbidity/mortality.

Dysplasia Of The Hip

Abstract Aims Developmental Dysplasia of the Hip (DDH) has been linked to high birth weight and packaging disorders, though the evidence is limited. This has implications on screening strategies. The aim of this study was to establish whether birth weight was truly associated with the incidence of DDH. Patients and Methods This cohort study analysed the birth weights of all babies born at our institution over a 24 month period, between 01/01/2017 and 01/01/2019. Babies with DDH and those without DDH were compared. Babies were excluded if born before 38 weeks, had incomplete data or were a non-singleton pregnancy. Sub-analysis was performed for DDH severity (dysplastic versus subluxed/dislocated hips), breech presentation, gestational age, gender and ethnicity. Statistical analysis was performed using SPSS. Results There were 10,113 babies born at our institution during the selected timeframe, of which 884 were excluded for prematurity, 336 for being non-singleton and 19 for incomplete data. This left 8874 for analysis, of which 95 babies had confirmed DDH. Both the Non-DDH and DDH data sets had normal distribution (Shapiro-Wilkes, p = 0.308 and 0.629, respectively), with mean birth weights of 3477.7 g with DDH and 3492.8 g without DDH. No difference in birth weight was found (Independent T test, p = 0.789). Females had a lower birth weight than males (3293.1 g versus 3416.6 g (p < 0.001)) yet have a higher incidence of DDH (ratio 6:1 in this dataset). No significant difference was found between birth weights of females with and without DDH (p = 0.068), nor between males with and without DDH (p = 0.513). There were no significant differences in birth weights even when only displaced hips were analysed (p = 0.543), nor according to breech presentation (p = 0.8). Longer gestation babies weighed more (p < 0.00001), yet showed no increase in DDH incidence (p = 0.64). Conclusion This study discredits the belief that DDH may be related to higher birth weight, thus casting doubt on the link to DDH being a packaging problem in utero. This, therefore, allows future research to prioritise the investigation of alternative aetiologies.

Pregnancy induced Hypertension (PIH) is strongly associated with intrauterine fetal growth restriction (IUGR), low birth weight (LBW) and admission to NICU. PIH is not by itself an indication for caesarean delivery. However, the incidence of caesarean is high because of the development of complications in mother and the need to deliver prematurely. To compare the immediate morbidity and survival advantage of LBW vertex presenting babies with the mode of delivery in hypertensive disorders complicating pregnancies. This was a comparative cross-sectional study done on women admitted to the labour ward during the study period with PIH delivering a baby through either a vaginal delivery or a caesarean section with a birthweight of &#60;2.5kgs. A detailed history taking and clinical examination was done. Babies were followed up for one week following delivery to note down the early neonatal outcome. In this study, over all there was no statistically significant difference in neonatal outcome in both vaginal delivery and caesarean section groups. However, there was slight increased incidence of prematurity (68% vs 64%), Birth Asphyxia (14% vs 8%), Sepsis (8% vs 6%), IVH (6% vs 2%) and Hyperbilirubinemia (16% vs 14%) in vaginal delivery group. While, RDS (20% vs 14%) and NEC (4% vs 2%) had higher incidence in caesarean delivery group. Overall, prematurity and IUGR resulting in LBW, contributed to these neonatal complications. Caesarean delivery offers no short-term survival advantage compared with vaginal delivery for LBW vertex presenting foetuses in PIH patients. Neonatal outcomes are not worsened by spontaneous or induced vaginal delivery in women with hypertension with good control and also decreases morbidity due to caesarean section to the mother.

Introduction: Birth weight is an important determinant of infant morbidity and mortality. Its effect extends upto adult life and may explain some non-communicable diseases that may occur in adult life. In general, males weigh more than females. Birth weight is categorised into three levels, viz., low, normal and high. This study analysed the relationship between gender and the categories of birth weights. Materials and Methods: Data on babies’ gender and birth weights from 961 term life deliveries in a private general practice hospital were analysed. Test on equality of the mean weight of males and females at the three categorical levels were done using z test and t-tests, as necessary. Results: Mean birth weight was found to be 3.30 ± 0.495 kg. Males weighed significantly heavier than females at mean weights of 3.343 ± 0.495 kg and 3.258 ± 0.490 kg, respectively. In the low birth weight category, males weighed 1.844 ± 0.297 kg and females weighed 1.992 ± 0.397 kg. There was no significant difference. Similarly, the mean weight of males and females in the high birth weight category were 4.462 ± 0.343 kg and 4.342 ± 0.219 kg, respectively with no significant difference. In the normal weight category, males weighed significantly more than the females with the mean weight of 3.30 ± 0.359 kg and 3.248 ± 0.392 kg, respectively. Conclusion: Male babies weighed more than female babies only in the normal birth weight category. The factor that selectively affected the birth weight of male babies must be acting under the category of normal birth weight only. More studies are necessary to identify the factors and the reasons, for which they act only at the level of the normal birth weight.

Background: Oxygen saturation measures the quantity of haemoglobin in the blood that is saturated with oxygen. Hemoglobin is a component of red blood cells that binds oxygen and transports it to outlying tissues. Oxygen is commonly used throughout the world in neonatal units. Injudicious use of Oxygen may not maintain appropriate oxygen status rather can lead to hypoxemia or hyperoxemia, both of the conditions are injurious to neonatal health. Objective: To assess the oxygen saturation in neonate after birth.Methods:A cross-sectional study conducted in the Department of Neonatology BSMMU, Shahbag, Dhaka, Lab Aid Specialized Hospital, Dhaka, Bangladesh from October 2013 to March 2014. A total 317 patients were selected according to selection criteria. The parents were interviewed with a specific pre-designed and pre-tested questionnaire and some information were gathered by document review. All neonate both term and late preterm (˃34weeks) who would not be anticipated for resuscitation was included.Results:A total 317 neonate were selected according to selection criteria. Among the study subjects more than half were male (57.1%). Rests were female (42.9%). Average gestational age of the study subjects was 37.47± 1.16 (SD) with the range of 34-40. On the other hand average birth weight was 2.88±0.46 (SD) with the minimum birth weight 2.0 kg and maximum weight 4.2 kg. Illustrates the median (IQR) heart rate from one to ten min for preterm versus term births. At one to three minutes and at five minutes after birth preterm infants had significantly lower SpO2 measurements. From six to 10 minutes after birth and four minutes after birth there was no significant difference between SpO2 measurements for mode of delivery. Paired sample t test showed that average SpO2 was less in 1 minute[88.42±4.8(SD)] than in 5 minute [94.25±3.5(SD)] and statistically this differences were highly significant (t=24.44, p=0.000). Pearson correlation showed high positive correlation (p=0.000) and correlation co-efficient r=0.479. Correlation was significant at the 0.01 level.Conclusion:It is “normal” to have low oxygen saturation measurements in the first minutes after birth. It takes time for infants to reach oxygen saturation levels described as “normal” in the later postnatal period. Oxygen saturation increased with time i.e., it was more in 5 minutes than in 1 minute and similarly more in 10 minutes than in 5 minutes. Conversely heart rate was found more in one minute than to five and ten minutes. Oxygen saturation was ≥ 90% within 3 to 4 minutes. Significant changes were found in Oxygen saturation by mode of delivery in three minutes & in heart rate by two minutes after birth. At one to ten minutes after birth preterm infants had lower SpO2 measurements.

Sub uterine involution is one of the pathological symptoms of the postpartum period, which causes complications. This is indicated by the size of the fundus uterine, which is greater than the normal size and elongated outflow of lochia. One of the non-pharmacological methods for preventing sub uterine involution is postpartum yoga which focuses on physical and breathing exercises, strengthening of the pelvic floor muscles, and relaxation of autosuggestions. The study aimed to analyze the effectiveness of postpartum yoga on uterine involution. A quasi-experimental, pre-test and post-test with the control group was applied in this study. Thirty-eight postpartum women received postpartum yoga as the intervention group. The control group was comprised of 19 women. The gain score of uterine involution in the intervention group was 9.14 ± 1.27 and in the control group 7.20 ± 1.11. The Cohen’s effect size test is 1.63. The result of the mann whitney test showed that there was a significant difference between the intervention group and the control group with p value 0,000. The result of determination (R Square), postpartum yoga had an effect of 40.3% on uterine involution after being controlled simultaneously with parity, frequency of breastfeeding, and anxiety. Postpartum yoga is effective to strengthen the uterine muscles, facilitate blood circulation, and stimulate neurohormonal so it could accelerate uterine involution. Further studies could measure of fundus uterine daily. Future researchers can develop postpartum yoga research with other variables such as anxiety, urinary incontinence, quality of life for postpartum women, and hormonal variables including oxytocin, endorphins, and cortisol.

Abstract Introduction Foetal macrosomia is associated with various obstetrical complications and is a common reason for inductions and primary or secondary Caesarean sections. The objective of this study is the generation of descriptive data on the mode of delivery and on maternal and foetal complications in the case of foetal macrosomia. The causes and consequences of foetal macrosomia as well as the rate of shoulder dystocia are examined in relation to the severity of the macrosomia. Patients The study investigated all singleton births ≥ 37 + 0 weeks of pregnancy with a birth weight ≥ 4000 g at the Charité University Medicine Berlin (Campus Mitte 2001 – 2017, Campus Virchow Klinikum 2014 – 2017). Results 2277 consecutive newborns (birth weight 4000 – 4499 g [88%], 4500 – 4999 g [11%], ≥ 5000 g [1%]) were included. Maternal obesity and gestational diabetes were more common in the case of newborns weighing ≥ 4500 g than newborns weighing 4000 – 4499 g (p = 0.001 and p < 0.001). Women with newborns ≥ 5000 g were more often ≥ 40 years of age (p = 0.020) and multipara (p = 0.025). The mode of delivery was spontaneous in 60% of cases, vaginal-surgical in 9%, per primary section in 14% and per secondary section in 17%. With a birth weight ≥ 4500 g, a vaginal delivery was more rare (p < 0.001) and the rate of secondary sections was increased (p = 0.011). Women with newborns ≥ 4500 g suffered increased blood loss more frequently (p = 0.029). There was no significant difference with regard to the rate of episiotomies or serious birth injuries. Shoulder dystocia occurred more frequently at a birth weight of ≥ 4500 g (5 vs. 0.9%, p = 0.000). Perinatal acidosis occurred in 2% of newborns without significant differences between the groups. Newborns ≥ 4500 g were transferred to neonatology more frequently (p < 0.001). Conclusion An increased birth weight is associated with an increased maternal risk and an increased rate of primary and secondary sections as well as shoulder dystocia; no differences in the perinatal outcome between newborns with a birth weight of 4000 – 4499 g and ≥ 4500 g were seen. In our collective, a comparably low incidence of shoulder dystocia was seen. In the literature, the frequency is indicated with a large range (1.9 – 10% at 4000 – 4499 g, 2.5 – 20% at 4500 – 5000 g and 10 – 20% at ≥ 5000 g). One possible cause for the low rate could be the equally low prevalence of gestational diabetes in our collective. A risk stratification of the pregnant women (e.g. avoidance of vacuum extraction, taking gestational diabetes into account during delivery planning) is crucial. If macrosomia is presumed, it is recommended that delivery take place at a perinatal centre in the presence of a specialist physician, due to the increased incidence of foetal and maternal complications.
