RESUMO

Newborns exposed to birth asphyxia transiently experience deficient blood flow and a lack of oxygen, potentially inducing hypoxic-ischaemic encephalopathy and subsequent neurological damage. Immunomodulatory components in plasma may dampen these responses. Using caesarean-delivered pigs as a model, we hypothesized that dietary plasma supplementation improves brain outcomes in pigs exposed to birth asphyxia. Mild birth asphyxia was induced by temporary occlusion of the umbilical cord prior to caesarean delivery. Motor development was assessed in asphyxiated (ASP) and control (CON) piglets using neonatal arousal, physical activity and gait test parameters before euthanasia on Day 4. The ASP pigs exhibited increased plasma lactate at birth, deficient motor skills and increased glial fibrillary acidic protein levels in CSF and astrogliosis in the putamen. The expression of genes related to oxidative stress, inflammation and synaptic functions was transiently altered in the motor cortex and caudate nucleus. The number of apoptotic cells among CTIP2-positive neurons in the motor cortex and striatal medium spiny neurons was increased, and maturation of preoligodendrocytes in the internal capsule was delayed. Plasma supplementation improved gait performance in the beam test, attenuated neuronal apoptosis and affected gene expression related to neuroinflammation, neurotransmission and antioxidants (motor cortex, caudate). We present a new clinically relevant animal model of moderate birth asphyxia inducing structural and functional brain damage. The components in plasma that support brain repair remain to be identified but may represent a therapeutic potential for infants and animals after birth asphyxia.

RESUMO

Unintentional misinterpretation of research in published biomedical reports that is not based on statistical flaws is often underrecognized, despite its possible impact on science, clinical practice, and public health. Important causes of such misinterpretation of scientific data, resulting in either false positive or false negative conclusions, include design-associated errors and hidden (or latent) variables that are not easily recognized during data analysis. Furthermore, cognitive biases, such as the inclination to seek patterns in data whether they exist or not, may lead to misinterpretation of data. Here, we give an example of these problems from hypothesis-driven research on the potential seasonality of neonatal seizures in a rat model of birth asphyxia. This commentary aims to raise awareness among the general scientific audience about the issues related to the presence of unintentional misinterpretation in published reports.

RESUMO

In the management of shoulder dystocia, it is often recommended to start with external maneuvers, such as the McRoberts maneuver and suprapubic pressure, followed by internal maneuvers including rotation and posterior arm delivery. However, this sequence is not based on scientific evidence of its success rates, the technical simplicity, or the related complication rates. Hence, this review critically evaluates the success rate, technique, and safety of different maneuvers. Retrospective reviews showed that posterior arm delivery has consistently higher success rates (86.1%) than rotational methods (62.4%) and external maneuvers (56.0%). McRoberts maneuver was thought to be a simple method, however, its mechanism is not clear. Furthermore, McRoberts position still requires subsequent traction on the fetal neck, which presents a risk for brachial plexus injury. The 2 internal maneuvers have anatomic rationales with the aim of rotating the shoulders to the wider oblique pelvic dimension or reducing the shoulder width. The techniques are not more sophisticated and requires the accoucher to insert the correct hand (according to fetal face direction) through the more spacious sacro-posterior region and deep enough to reach the fetal chest or posterior forearm. The performance of rotation and posterior arm delivery can also be integrated and performed using the same hand. Retrospective studies may give a biased view that the internal maneuvers are riskier. First, a less severely impacted shoulder dystocia is more likely to have been managed by external maneuvers, subjecting more difficult cases to internal maneuvers. Second, neonatal injuries were not necessarily caused by the internal maneuvers that led to delivery but could have been caused by the preceding unsuccessful external maneuvers. The procedural safety is not primarily related to the nature of the maneuvers, but to how properly these maneuvers are performed. When all these maneuvers have failed, it is important to consider the reasons for failure otherwise repetition of the maneuver cycle is just a random trial and error. If the posterior axilla is just above the pelvic outlet and reachable, posterior axilla traction using either the accoucher fingers or a sling is a feasible alternative. Its mechanism is not just outward traction but also rotation of the shoulders to the wider oblique pelvic dimension. If the posterior axilla is at a higher sacral level, a sling may be formed with the assistance of a long right-angle forceps, otherwise, more invasive methods such as Zavanelli maneuver, abdominal rescue, or symphysiotomy are the last resorts.

RESUMO

OBJECTIVE: To determine the incidence and sociodemographic and clinical risk factors associated with birth asphyxia and the immediate neonatal outcomes of birth asphyxia in Nigeria. DESIGN: Secondary analysis of data from the Maternal and Perinatal Database for Quality, Equity and Dignity Programme. SETTING: Fifty-four consenting referral-level hospitals (48 public and six private) across the six geopolitical zones of Nigeria. POPULATION: Women (and their babies) who were admitted for delivery in the facilities between 1 September 2019 and 31 August 2020. METHODS: Data were extracted and analysed on prevalence and sociodemographic and clinical factors associated with birth asphyxia and the immediate perinatal outcomes. Multilevel logistic regression modelling was used to ascertain the factors associated with birth asphyxia. MAIN OUTCOME MEASURES: Incidence, case fatality rate and factors associated with birth asphyxia. RESULTS: Of the available data, 65 383 (91.1%) women and 67 602 (90.9%) babies had complete data and were included in the analysis. The incidence of birth asphyxia was 3.0% (2027/67 602) and the case fatality rate was 16.8% (339/2022). The risk factors for birth asphyxia were uterine rupture, pre-eclampsia/eclampsia, abruptio placentae/placenta praevia, birth trauma, fetal distress and congenital anomaly. The following factors were independently associated with a risk of birth asphyxia: maternal age, woman's education level, husband's occupation, parity, antenatal care, referral status, cadre of health professional present at the birth, sex of the newborn, birthweight and mode of birth. Common adverse neonatal outcomes included: admission to a special care baby unit (SCBU), 88.4%; early neonatal death, 14.2%; neonatal sepsis, 4.5%; and respiratory distress, 4.4%. CONCLUSIONS: The incidence of reported birth asphyxia in the participating facilities was low, with around one in six or seven babies with birth asphyxia dying. Factors associated with birth asphyxia included sociodemographic and clinical considerations, underscoring a need for a comprehensive approach focused on the empowerment of women and ensuring access to quality antenatal, intrapartum and postnatal care.

RESUMO

BACKGROUND: Peripartum asphyxia is one of the main causes of neonatal morbidity and mortality. In moderate and severe cases of asphyxia, a condition called hypoxic-ischemic encephalopathy (HIE) and associated permanent neurological morbidities may follow. Due to the multifactorial etiology of asphyxia, it may be difficult prevent, but in term neonates, therapeutic cooling can be used to prevent or reduce permanent brain damage. The aim of this study was to assess the significance of different antenatal and delivery related risk factors for moderate and severe HIE and the need for therapeutic hypothermia. METHODS: We conducted a retrospective matched case-control study in Helsinki University area hospitals during 2013-2017. Newborn singletons with moderate or severe HIE and the need for therapeutic hypothermia were included. They were identified from the hospital database using ICD-codes P91.00, P91.01 and P91.02. For every newborn with the need for therapeutic hypothermia the consecutive term singleton newborn matched by gender, fetal presentation, delivery hospital, and the mode of delivery was selected as a control. Odds ratios (OR) between obstetric and delivery risk factors and the development of HIE were calculated. RESULTS: Eighty-eight cases with matched controls met the inclusion criteria during the study period. Maternal and infant characteristics among cases and controls were similar, but smoking was more common among cases (aOR 1.46, CI 1.14-1.64, p = 0.003). The incidence of preeclampsia, diabetes and intrauterine growth restriction in groups was equal. Induction of labour (aOR 3.08, CI 1.18-8.05, p = 0.02) and obstetric emergencies (aOR 3.51, CI 1.28-9.60, p = 0.015) were more common in the case group. No difference was detected in the duration of the second stage of labour or the delivery analgesia. CONCLUSIONS: Smoking, induction of labour and any obstetric emergency, especially shoulder dystocia, increase the risk for HIE and need for therapeutic hypothermia. The decisions upon induction of labour need to be carefully weighed, since maternal smoking and obstetric emergencies can hardly be controlled by the clinician.

RESUMO

BACKGROUND: Birth asphyxia is the main cause of neonatal mortality and morbidity worldwide. Some studies indicate intimate partner violence during pregnancy is a risk factor for birth asphyxia. In Ethiopia, intimate partner violence during pregnancy is reported to be high. Despite this high prevalence, there is a lack of data about the association of birth asphyxia and intimate partner violence. The aim of this study was to assess the prevalence of intimate partner violence during pregnancy and its associated factors with birth asphyxia in health facilities in the Tigray region of northern Ethiopia. METHODS: This was an institutional-based cross-sectional study conducted at select health facilities in the Tigray region of Ethiopia. Random sampling technique was employed to select health facilities and systematic sampling was used to select 648 study participants. Data was entered by using Epi info version 3.5.1 and was analyzed using SPSS version 20. Bivariate and multivariate analysis was done to assess the association between exposure to intimate partner violence during pregnancy and birth asphyxia after adjusting for possible confounders. RESULTS: The prevalence of intimate partner violence during pregnancy was 47(7.3%). Eighty two (12.7%) babies were delivered with birth asphyxia. Intimate partner violence during pregnancy had a significant association with birth asphyxia, AOR (95% CI) = 4.4(2-9.8). In addition to this, other factors that were associated with birth asphyxia include place of residence [ AOR (95% CI) = 2.7(1.55-4.8)], age > 19 [AOR (95% CI) = 2.9(1.29-6.5)], age 20-35 [AOR (95% CI) = 3.1(1.06-9.3)], gestational age < 37 weeks [AOR(95% CI) = 7.2(3.5-14.8)] and low birth weight [AOR(95% CI) = 3.9(2.1-7.3)]. CONCLUSIONS: The prevalence of birth asphyxia in this study is high and is further increased by intimate partner violence during pregnancy. Health care providers and policy makers should take measures aimed at preventing intimate partner violence during pregnancy to reduce harm to the mother and adverse birth outcomes.

RESUMO

Birth asphyxia is a potential cause of death that is also associated with acute and chronic morbidities. The traditional and immediate approach for monitoring birth asphyxia (i.e., arterial blood gas analysis) is highly invasive and intermittent. Additionally, alternative noninvasive approaches such as pulse oximeters can be problematic, due to the possibility of false and erroneous measurements. Therefore, further research is needed to explore alternative noninvasive and accurate monitoring methods for asphyxiated neonates. This study aims to investigate the prominent ECG features based on pH estimation that could potentially be used to explore the noninvasive, accurate, and continuous monitoring of asphyxiated neonates. The dataset used contained 274 segments of ECG and pH values recorded simultaneously. After preprocessing the data, principal component analysis and the Pan-Tompkins algorithm were used for each segment to determine the most significant ECG cycle and to compute the ECG features. Descriptive statistics were performed to describe the main properties of the processed dataset. A Kruskal-Wallis nonparametric test was then used to analyze differences between the asphyxiated and non-asphyxiated groups. Finally, a Dunn-Sidák post hoc test was used for individual comparison among the mean ranks of all groups. The findings of this study showed that ECG features (T/QRS, T Amplitude, Tslope, Tslope/T, Tslope/|T|, HR, QT, and QTc) based on pH estimation differed significantly (p < 0.05) in asphyxiated neonates. All these key ECG features were also found to be significantly different between the two groups.

RESUMO

OBJECTIVE: To compare the effect of intact cord versus clamped cord resuscitation on the physiologic transition of neonates receiving positive-pressure ventilation (PPV) at birth. STUDY DESIGN: This open-label, parallel-group, randomized controlled superiority trial was conducted in a tertiary care hospital in India. Neonates born at ≥34 weeks of gestation after a complicated pregnancy or labor were randomized just before birth to receive resuscitation according to the Neonatal Resuscitation Program algorithm with either an intact cord (intact cord resuscitation group) or after early cord clamping (early cord clamping resuscitation group). The allocated study intervention was administered if the neonate needed PPV at birth. The primary outcome was expanded Apgar score at 5 minutes after birth. RESULTS: Birth weight, gestational age, and the incidence of pregnancy complications were similar in the 2 study groups. The proportion of neonates who received PPV was lower in the intact cord resuscitation group (28.7% vs 36.5%, P = .05; relative risk, 0.79; 95% CI, 0.61-1.01). Among neonates who received PPV, the expanded Apgar score at 5 minutes was significantly higher in the intact cord resuscitation group (median, 15 [IQR, 14-15] vs 14 [IQR, 13-15]; P < .001). The expanded Apgar score at 10 minutes, Apgar scores at 5 and 10 minutes, and oxygen saturation at 1, 5, and 10 minutes were also higher in the intact cord resuscitation group. CONCLUSION: In late preterm and term neonates, resuscitation with an intact cord results in better postnatal physiologic transition than the standard practice of resuscitation after immediate cord clamping.

RESUMO

BACKGROUND: Developing a prediction model that incorporates several risk factors and accurately calculates the overall risk of birth asphyxia is necessary. The present study used a machine learning model to predict birth asphyxia. METHODS: Women who gave birth at a tertiary Hospital in Bandar Abbas, Iran, were retrospectively evaluated from January 2020 to January 2022. Data were extracted from the Iranian Maternal and Neonatal Network, a valid national system, by trained recorders using electronic medical records. Demographic factors, obstetric factors, and prenatal factors were obtained from patient records. Machine learning was used to identify the risk factors of birth asphyxia. Eight machine learning models were used in the study. To evaluate the diagnostic performance of each model, six metrics, including area under the receiver operating characteristic curve, accuracy, precision, sensitivity, specificity, and F1 score were measured in the test set. RESULTS: Of 8888 deliveries, we identified 380 women with a recorded birth asphyxia, giving a frequency of 4.3%. Random Forest Classification was found to be the best model to predict birth asphyxia with an accuracy of 0.99. The analysis of the importance of the variables showed that maternal chronic hypertension, maternal anemia, diabetes, drug addiction, gestational age, newborn weight, newborn sex, preeclampsia, placenta abruption, parity, intrauterine growth retardation, meconium amniotic fluid, mal-presentation, and delivery method were considered to be the weighted factors. CONCLUSION: Birth asphyxia can be predicted using a machine learning model. Random Forest Classification was found to be an accurate algorithm to predict birth asphyxia. More research should be done to analyze appropriate variables and prepare big data to determine the best model.

RESUMO

BACKGROUND: Birth asphyxia is of significant concern because it impacts newborn health from low to severe levels. In Thailand, birth asphyxia remains a leading cause of delayed developmental health in children under 5 years old. The study aimed to determine the maternal, fetal and health service factors contributing to birth asphyxia. METHODS: A case-control design was conducted on a sample of 4256 intrapartum chart records. The samples were selected based on their Apgar scores in the first minute of life. A low Apgar score (≤ 7) was chosen for the case group (852) and a high Apgar score (> 7) for the control group (3408). In addition, a systematic random technique was performed to select 23 hospitals, including university, advanced and secondary, in eight health administration areas in Thailand for evaluating the intrapartum care service. Data analysis was conducted using SPSS statistical software. RESULTS: The odds of birth asphyxia increases in the university and advanced hospitals but the university hospitals had the highest quality of care. The advanced and secondary hospitals had average nurse work-hours per week of more than 40 h. Multivariable logistic regression analysis found that intrapartum care services and maternal-fetal factors contributed to birth asphyxia. The odd of birth asphyxia increases significantly in late-preterm, late-term pregnancies, low-birth weight, and macrosomia. Furthermore, maternal comorbidity, non-reassuring, and obstetric emergency conditions significantly increase the odd of birth asphyxia. In addition, an excellent quality of intrapartum care, a combined nursing model, low nurse work-hours, and obstetrician-conducted delivery significantly reduced birth asphyxia. CONCLUSION: Birth asphyxia problems may be resolved in the health service management offered by reducing the nurse work-hours. Excellent quality of care required the primary nursing care model combined with a team nursing care model. However, careful evaluation and monitoring are needed in cases of comorbidity, late-preterm, late-term pregnancies, low-birth weight, and macrosomia. Furthermore, increasing the obstetrician availability in obstetric emergencies and non-reassuring fetal status is important.

RESUMO

BACKGROUND: Umbilical cord blood gases are routinely used by midwives and obstetricians for quality assurance of birth management and in clinical research. They can form the basis for solving medicolegal issues in the identification of severe intrapartum hypoxia at birth. However, the scientific value of veno-arterial differences in cord blood pH, also known as ΔpH, is largely unknown. By tradition, the Apgar score is frequently used to predict perinatal morbidity and mortality, however significant inter-observer and regional variations decrease its reliability and there is a need to identify more accurate markers of perinatal asphyxia. The aim of our study was to investigate the association of small and large veno-arterial differences in umbilical cord pH, ΔpH, with adverse neonatal outcome. METHODS: This retrospective, population-based study collected obstetric and neonatal data from women giving birth in nine maternity units from Southern Sweden from 1995 to 2015. Data was extracted from the Perinatal South Revision Register, a quality regional health database. Newborns at ≥37 gestational weeks with a complete and validated set of umbilical cord blood samples from both cord artery and vein were included. Outcome measures included: ΔpH percentiles, 'Small ΔpH' (10th percentile), 'Large ΔpH' (90th percentile), Apgar score (0-6), need for continuous positive airway pressure (CPAP) and admission to neonatal intensive care unit (NICU). Relative risks (RR) were calculated with modified Poisson regression model. RESULTS: The study population comprised of 108,629 newborns with complete and validated data. Mean and median ΔpH was 0.08 ± 0.05. Analyses of RR showed that 'Large ΔpH' was associated with a decreased RR of adverse perinatal outcome with increasing UApH (at UApH ≥7.20: RR for low Apgar 0.29, P = 0.01; CPAP 0.55, P = 0.02; NICU admission 0.81, P = 0.01). 'Small ΔpH' was associated with an increased RR for low Apgar score and NICU admission only at higher UApH values (at UApH 7.15-7.199: RR for low Apgar 1.96, P = 0.01; at UApH ≥7.20: RR for low Apgar 1.65, P = 0.00, RR for NICU admission 1.13, P = 0.01). CONCLUSION: Large differences between cord venous and arterial pH (ΔpH) at birth were associated with a lower risk for perinatal morbidity including low 5-minute Apgar Score, the need for continuous positive airway pressure and NICU admission when UApH was above 7.15. Clinically, ΔpH may be a useful tool in the assessment of the newborn's metabolic condition at birth. Our findings may stem from the ability of the placenta to adequately replenish acid-base balance in fetal blood. 'Large ΔpH' may therefore be a marker of effective gas exchange in the placenta during birth.

RESUMO

AIM: Hypoxic-ischaemic encephalopathy (HIE) is one of the leading causes of neonatal deaths and neurological impairment with the highest impact in resource-limited settings. This study aimed to determine the incidence of poor in-hospital outcomes and related factors among newborns with HIE in Tanzania. METHODS: A prospective observational study in which 170 newborns with HIE (diagnosed using the Thompson clinical score) were followed from 1 September 2020 to 28 February 2021 at the neonatal ward of Dodoma Regional Referral Hospital in Dodoma, central Tanzania, until discharge or death. Clinical parameters were recorded. Multinomial logistic regression analysis was applied to determine factors associated with adverse outcomes. RESULTS: Out of 170 newborns, 44.7% (76/170) had poor outcomes (death 27.1% (46/170); neurological deficits 17.6% (30/170)). Severe HIE (Thompson score > 14) (p < 0.0001), history of aspiration (adjusted odds ratio (AOR) = 3.06, 95% confidence interval (CI) [1.170, 8.014], p = 0.0226) and 5th-min APGAR of <7 (AOR = 2.88, 95% CI [1.133, 7.310], p = 0.0262) were associated with mortality. Severe HIE, delivery at other facilities (AOR = 3.106 CI [1.158, 8.332], p = 0.0244) and abnormal heart rate (<100 or ≥160 beats/min) on admission (AOR = 3.469 [1.200, 10.030], p = 0.0216) predicted neurological impairment at discharge. CONCLUSION: Hypoxic-ischaemic encephalopathy is associated with a high incidence of poor outcomes in resource-limited settings. To improve outcomes newborns with severe HIE, history of aspiration, referred from other facilities, 5th-min APGAR score of <7 and abnormal heart rate need improved quality of neonatal care.

RESUMO

AIM: The aim of this study was to investigate how individual markers for birth asphyxia, so-called A criteria, were associated with the probability of receiving therapeutic hypothermia. METHODS: This population-based cohort study included 1336 live-born singleton term infants with any A criterion in the Stockholm-Gotland Region, Sweden during 2008 to 2014. The Swedish Neonatal Quality Register and National Patient Register were used for data collection. Results were presented as adjusted odds ratios (aORs) with 95% confidence intervals (CIs). RESULTS: There were 89 infants, 44 boys and 45 girls with mean gestational age 40.5 weeks, who received therapeutic hypothermia. Low Apgar score, aOR 12.44 (95% CI 5.99-25.86), and resuscitation, aOR 9.18 (95% CI 3.77-22.34), were strongly associated with therapeutic hypothermia. A pH <7.0 was less associated with the outcome, aOR 2.02 (95% CI 1.02-4.0). No infant who received therapeutic hypothermia fulfilled the criteria of base deficit ≥16 mmol/L only. CONCLUSION: A low Apgar score of and/or a need for resuscitation is more relevant for identifying infants eligible for therapeutic hypothermia, compared to other A criteria. This knowledge could be used clinically to identify cases for review and avoid unnecessary monitoring of infants.

RESUMO

BACKGROUND: Birth asphyxia is one of the leading causes of neonatal mortality worldwide. In Uganda, it accounts for 28.9% of all neonatal deaths. With a view to inform policy and practice interventions to reduce adverse neonatal outcomes, we aimed to determine the prevalence and factors associated with birth asphyxia at two referral hospitals in Northern Uganda. METHODS: This was a cross-sectional study, involving women who gave birth at two referral hospitals. Women in labour were consecutively enrolled by the research assistants, who also attended the births and determined Apgar scores. Data on socio-demographic characteristics, pregnancy history and care during labour, were obtained using a structured questionnaire. Participants were tested for; i) malaria (peripheral and placental blood samples), ii) syphilis, iii) white blood cell counts (WBC), and iv) haemoglobin levels. The prevalence of birth asphyxia was determined as the number of newborns with Apgar scores < 7 at 5 min out of the total population of study participants. Factors independently associated with birth asphyxia were determined using multivariable logistic regression analysis and a p-value < 0.05 was considered statistically significant. RESULTS: A total of 2,930 mother-newborn pairs were included, and the prevalence of birth asphyxia was 154 [5.3% (95% confidence interval: 4.5- 6.1)]. Factors associated with birth asphyxia were; maternal age ≤ 19 years [adjusted odds ratio (aOR) 1.92 (1.27-2.91)], syphilis infection [aOR 2.45(1.08-5.57)], and a high white blood cell count [aOR 2.26 (1.26-4.06)], while employment [aOR 0.43 (0.22-0.83)] was protective. Additionally, referral [aOR1.75 (1.10-2.79)], induction/augmentation of labour [aOR 2.70 (1.62-4.50)], prolonged labour [aOR 1.88 (1.25-2.83)], obstructed labour [aOR 3.40 (1.70-6.83)], malpresentation/ malposition [aOR 3.00 (1.44-6.27)] and assisted vaginal delivery [aOR 5.54 (2.30-13.30)] were associated with birth asphyxia. Male newborns [aOR 1.92 (1.28-2.88)] and those with a low birth weight [aOR 2.20 (1.07-4.50)], were also more likely to develop birth asphyxia. CONCLUSION: The prevalence of birth asphyxia was 5.3%. In addition to the known intrapartum complications, teenage motherhood, syphilis and a raised white blood cell count were associated with birth asphyxia. This indicates that for sustained reduction of birth asphyxia, appropriate management of maternal infections and improved intrapartum quality of care are essential.

RESUMO

BACKGROUND: Birth asphyxia is the inability of a newborn to start and conserve breathing immediately after birth. Globally, 2.5 million infants die within their first month of life every year, contributing nearly 47% of all deaths of children. It is the third cause of neonatal deaths next to infections and preterm birth. Ethiopia is one of the countries with the highest neonatal mortality and high burden of birth asphyxia in the world. The state of birth asphyxia is about 22.52% in Ethiopia, with incidence of 18.0% in East Africa Neonatal mortality incidence ratio was 9.6 deaths per 1000 live births among which 13.5% of neonatal mortality cases were due to birth asphyxia in southern Ethiopia. The effect of birth asphyxia is not only limited to common clinical problems and death; it also has a socio-economic impact on the families. Therefore, this study is aimed to identify determinants of birth asphyxia among newborn live births in public hospitals Southern Ethiopia. METHODS: An Institution based unmatched case-control study was conducted among newborn live births in public hospitals of Gamo & Gofa zones, with a total sample size of 356 (89 cases and 267 controls, 1:3 case to control ratio) from March 18 to June 18, 2021, after obtaining ethical clearance from Arba Minch University. Cases were selected consecutively and controls were selected by systematic random sampling method. Data were collected using an adapted pretested semi-structured questionnaire through face-to-face interviews and record reviews using an extraction checklist for intrapartum & neonatal-related information. The collected data were entered into Epi data version 4.4 and exported to STATA version 14 for analysis. Finally, bi-variable and multivariable logistic regression analyses were performed to identify determinants of birth asphyxia. Statistical significance was declared at p-value ≤ 0.05 along with corresponding 95% CI of AOR used to declare statistical significance. RESULTS: Anemia during pregnancy [AOR = 3.87, 95% CI (1.06- 14.09)], breech presentation [AOR = 3.56, 95% CI (1.19-10.65)], meconium stained amniotic fluid [AOR = 6.16, 95% CI (1.95-19.46)], cord prolapse [AOR = 4.69, 95%CI (1.04-21.05)], intrapartum fetal distress [AOR = 9.83, 95% CI (3.82-25.25)] and instrumental delivery [AOR = 5.91, 95% CI (1.51-23.07)] were significantly associated with birth asphyxia. CONCLUSION: The study revealed that anemia during pregnancy, breech presentation, meconium-stained amniotic fluid, cord prolapse, intrapartum fetal distress, and instrumental delivery were identified as determinants of birth asphyxia. Therefore, health professional and health institutions should give emphasis on care of mother and the newborn in actively detecting and managing asphyxia.

RESUMO

BACKGROUND: Birth asphyxia is the major public health problem in the world. It is estimated that around 23% of all newborn deaths are caused by birth asphyxia worldwide. Birth asphyxia is the top three causes of newborn deaths in sub-Saharan Africa and more than one-third of deaths in Ethiopia. Therefore, the aim of this study was to identify determinants of birth asphyxia which can play a crucial role to decrease the death of newborns. METHODS: Unmatched case-control study design was implemented among 276 (92 cases and 184 controls) newborns from January 1st to March 30th, 2020. A systematic sampling technique was used to select the study participants. Data were collected by using a semi-structured interviewer-administered questionnaire and document review by trained nurses and midwives who work at the delivery ward of the hospitals. Bivariate logistic regression analysis was done to identify determinants of birth asphyxia. Adjusted odds ratios with 95% confidence intervals and p-value less than and equal to 0.05 were used to assess the level of significance. RESULTS: In this study, maternal education of being can't read & write [AOR = 4.7, 95% CI: (1.2, 11.9)], ante-partum hemorrhage [AOR = 7.7, 95% CI: (1.5, 18.5)], prolonged labor [AOR =13.5, 95% CI: (2.0, 19.4)], meconium stained amniotic fluid [AOR = 11.3, 95% CI: (2.7, 39.5)], breech fetal presentation [AOR = 4.5, 95% CI: (2.0, 8.4)] and preterm birth [AOR: 4.1, 95% CI: (1.8, 9.2)] were factors which showed significantly associated with birth asphyxia among newborns. CONCLUSIONS: In this study, maternal education can't read & write, antepartum hemorrhage, prolonged labor, stained amniotic fluid, breech fetal presentation, preterm birth were significantly associated with birth asphyxia. So, educating mothers to enhance health-seeking behaviors and close monitoring of the labor and fetus presentation were recommended to reduce birth asphyxia.

RESUMO

BACKGROUND: The leading cause of neonatal death worldwide is birth asphyxia. Yearly, in the first month of life, 2.5 million children died around the world. Birth asphyxia is a major problem, particularly in developing nations like Ethiopia. The goal of this study was to determine the magnitude of birth asphyxia and the factors that contributed to it among neonates delivered at the Aykel Primary Hospital in north-central Ethiopia. METHODS: From August 1 to August 31, 2021, a hospital-based cross-sectional study was conducted on 144 live births. An Apgar score less than 7 in the fifth minute of birth authorized the diagnosis of birth asphyxia. Variable contention (P < 0.250) for multivariable analysis was determined after data examination and cleaning. Then, to identify important factors of birth asphyxia, a multivariable logistic regression model with a p-value of 0.05 was developed. Finally, a significant relationship between a dependent variable and independent factors was defined as a p-value less than 0.05 with a 95% confidence interval. RESULTS: The majority of the mothers, 71.53%, received at least one Antenatal care visit, and more than half of the newborns were male (62.50%). The percentage of neonates that had asphyxia at delivery was 11.11% (95% CI: 6.3 -16.9%). Male newborns were 5.02 times more probable than female newborns to asphyxiate [AOR: 5.02, 95% CI (1.11-22.61)]. Mothers who have not had at least one Antenatal Care visit were 3.72 times more likely to have an asphyxiated newborn than those who have at least one Antenatal Care visit [AOR: 3.72, 95%CI (1.11-12.42)]. Similarly, mothers who had an adverse pregnancy outcome were 7.03 times more likely to have an asphyxiated newborn than mothers who had no such history [AOR: 7.03, 95% CI (2.17-22.70)]. CONCLUSION: Birth asphyxia in newborn has come to a standstill as a major public health issue. The sexual identity of the newborn, Antenatal Care visits, and a history of poor pregnancy outcomes were all found to be significant risk factors for birth asphyxia. These findings have great importance for various stakeholders who are responsible for reducing birth asphyxia; in addition, policymakers should establish and revise guidelines associated to newborn activities and workshops.

RESUMO

BACKGROUND: Birth asphyxia leads to profound systemic and neurological sequela to decrease blood flow or oxygen to the fetus followed by lethal progressive or irreversible life-long pathologies. In low resource setting countries, birth asphyxia remains a critical condition. This study aimed to develop and validate prognostic risk scores to forecast birth asphyxia using maternal and neonatal characteristics in south Gondar zone hospitals. METHODS: Prospective cohorts of 404 pregnant women were included in the model in south Gondar Zone Hospitals, Northwest Ethiopia. To recognize potential prognostic determinants for birth asphyxia, multivariable logistic regression was applied. The model discrimination probability was checked using the receiver operating characteristic curve (AUROC) and the model calibration plot was assessed using the 'givitiR' R-package. To check the clinical importance of the model, a cost-benefit analysis was done through a decision curve and the model was internally validated using bootstrapping. Lastly, a risk score prediction measurement was established for simple application. RESULTS: Of 404, 108 (26.73%) (95% CI: 22.6-31.3) newborns were exposed to birth asphyxia during the follow-up time. Premature rupture of membrane, meconium aspiration syndrome, malpresentation, prolonged labor, Preterm, and tight nuchal was the significant prognostic predictors of birth asphyxia. The AUROC curve for birth asphyxia was 88.6% (95% CI: 84.6-92.2%), which indicated that the tool identified the newborns at risk for birth asphyxia very well. The AUROC of the simplified risk score algorithm, was 87.9 (95% CI, 84.0- 91.7%) and the risk score value of 2 was selected as the optimal cut-off value, with a sensitivity of 78.87%, a specificity of 83.26%, a positive predictive value of 63.23%, and a negative predictive value of 91.52%. CONCLUSIONS: We established birth asphyxia prediction tools by applying non-sophisticated maternal and neonatal characteristics for resource scares countries. The driven score has very good discriminative ability and prediction performance. This risk score tool would allow reducing neonatal morbidity and mortality related to birth asphyxia. Consequently, it will improve the overall neonatal health / under-five child health in low-income countries.

RESUMO

BACKGROUND: Helping Babies Breathe (HBB) is an American Academy of Pediatrics neonatal resuscitation program designed to reduce neonatal mortality in low resource settings. The 2017 neonatal mortality rate in Haiti was 28 per 1000 live births and an estimated 85 % of Haitian women deliver at home. Given this, the Community Health Initiative implemented an adapted HBB (aHBB) in Haiti to evaluate neonatal mortality. METHODS: Community Health Workers taught an aHBB program to laypeople, which didn't include bag-valve-mask ventilation. Follow-up after delivery assessed for maternal and neonatal mortality and health. RESULTS: Analysis included 536 births of which 84.3 % (n=452) were attended by someone trained in aHBB. The odds of neonatal mortality was not significantly different among the two groups (aOR=0.48 [0.16-1.44]). Composite outcome of neonatal health as reported by the mother (subjective morbidity and mortality) was significantly lower in aHBB attended births (aOR=0.31 [0.14-0.70]). CONCLUSION: This analysis of the aHBB program indicates that community training to laypersons in low resource settings may reduce neonatal ill-health but not neonatal mortality. This study is likely underpowered to find a difference in neonatal mortality. Further work is needed to evaluate which components of the aHBB program are instrumental in improving neonatal health.

RESUMO

BACKGROUND: Globally more than 650,000 newborns died on their first day of life from birth asphyxia. The outcome of an asphyxiated newborn depends on the quality of care they received at birth. However, the quality of care newborns received at birth may be below the WHO resuscitation standard. The reason for the poor quality of care is unclear. The Donabedian model, according to the World Health Organization (WHO), is an appropriate framework for health care assessment that focuses on improving the quality of care. So this study aims to assess the quality of neonatal resuscitation, outcome, and its associated factors among newborns with birth asphyxia at public hospitals in the East Wollega zone, 2021. METHODS: An institution-based cross-sectional study was conducted to observe 410 asphyxiated newborns using consecutive sampling methods. Data was gathered using a pretested structured questionnaire and checklist. Epi-data version 3.1 was used to enter data, which was subsequently exported to Statistical Package for Social Sciences version 25 for analysis. A logistic regression model was employed to determine the variables associated with the outcome variable. The adjusted odds ratio with a 95% confidence interval was calculated, and all variables associated with the outcome variable with a p-value less than 0.05 in multivariable analysis were determined to be significant factors for the outcome of resuscitated newborns. RESULT: A total of 410 asphyxiated newborns were included in this study with a response rate of 97%. From this 87.6% of resuscitated newborns survived. Keeping baby warm [AOR = 6.9; CI (3.1, 15.6)] is associated significantly with increased chances of survival while meconium presence in the airway [AOR = 0.26; CI (0.1, 0.6)], prematurity [AOR = 0.24; CI (0.12, 0.48)], and presence of cord prolapse [AOR = 0.08; CI (0.03, 0.19)] were factors significantly associated with decreased survival of resuscitated newborns at 1 h of life. CONCLUSION: Newborns who were kept warm were more likely to survive compared to their counterparts. While the presence of meconium in the airway, preterm, and cord prolapse was associated with the decreased survival status of newborns. Facilitating referral linkage in the event of cord prolapse, counseling on early antenatal care initiation to decrease adverse outcomes (prematurity), and neonatal resuscitation refresher training is strongly recommended.
