- ItemOpen AccessAetiology of stillbirths and adverse newborn outcomes at Queen Elizabeth central hospital, Blantyre, Malaw(2017-07-01) Chilinda, George KassimDeath of an infant in utero or at birth is a devastating experience for the mother and of concern in clinical practice. Developing countries struggle to provide comprehensive care to pregnant mothers and the new born. Stillbirths are common in poor countries that their occurrence is perceived inevitable. We aimed to characterize factors associated with stillbirth in our referral hospital population.Intrapartum birth asphyxia is a major contributor of high perinatal mortality in resource limited countries like Malawi. In low and middle income countries, about 59 % of the stillbirths are intrapartum unlike in developed countries where it is significantly lower than 10%. Studies done in Malawi have shown that birth asphyxia is a common cause of stillbirth. Furthermore, babies born with asphyxia may have increased long-term morbidity such as cerebral palsy, hence the need to identify new-borns at risk. The analysis of umbilical cord blood gases has been shown to be the gold standard for diagnosis of near-birth metabolic acidosis. Lactate has emerged as the preferred marker of acidosis in clinical practice. To determine the aetiology of stillbirths and adverse new-born outcomes among women delivering at Queen Elizabeth Central Hospital (QECH), Blantyre, Malawi This was a cross-section study done in two phases. In the first phase, data on all stillbirths that occurred at QECH between 1st August 2016 and 31st September 2016 was collected from the labour ward and Chatinkha operating theatre registries and patients’ files. All mothers of stillborn babies during the study period gave informed consent to participate in the study and have their blood samples collected and tested for VDRL, malaria, haemoglobin and fasting blood sugar on the bedside using point of care syphilis testing kit (Determine), malaria rapid diagnostic testing kit, Hemacue and glucometer respectively. The stillbirths were classified using the RECODE system The second phase was undertaken during April 2017. Data on all 401 births that occurred at QECH were collected from the labour ward and operating theatre registries and patients’ files. For all live births, umbilical arterial blood was drawn from a double clamped segment into heparinised plastic syringes. Lactate concentration in Umbilical cord arterial blood was analysed using Nova biomedical point of care devices within 15 minutes. All mothers had their blood samples collected and tested for VDRL, malaria, haemoglobin and fasting blood sugar at the bedside using point of care syphilis testing kit (Determine), malaria rapid diagnostic testing kit, Hemacue and glucometer respectively. During the first phase of the study, there were 54 stillbirths among 2149 deliveries translating to 25.1/1000births with 61% fresh stillbirths and 35% macerated stillbirth. 34% of the stillbirths were delivered through Caesarean section that was done after more than an hour from decision to undertake the procedure. Common relevant conditions at delivery were anaemia (52%), asphyxia (40%), hypertensive disorders (29%), placenta abruption ix (27%), HIV (25%) and syphilis (15%). None of the mothers had malaria or diabetes Mellitus. In phase two, the perinatal mortality was 44.9/1000births. The leading documented cause of nursery admission was birth asphyxia (41.7%). Shortage of theatre space accounted for all delays to do emergency Caesarean sections. Hyperlactatemia was associated with emergency caesarean sections, meconium stained liquor and vertex vaginal deliveries. There was no association between Hyperlactatemia and antepartum haemorrhage, gestational age, multiple gestation, PPROM, anaemia or malaria. Logistic regression modelling revealed that the odds of a composite adverse outcome (early neonatal death or admission to the neonatal unit) were significantly elevated in the presence of maternal hypertension (OR=2.9, P=0.019(95% C.I. 1.19-7.26)) after adjusting for the degree of hyperlactatemia. The study highlighted the risk factors for stillbirths at QECH. The risk factors for stillbirths at QECH include; preeclampsia, abruption placenta, anaemia, syphilis, and asphyxia. Poor intrapartum care attributed to lack of theatre capacity was the single most important cause of fresh stillbirths. None of the participating mothers had diabetes mellitus or malaria contrary to findings from other studies where both conditions were associated with increased risk of stillbirth. The ANC coverage was adequate, however, the quality of care provided in the centres needs improvement especially with regard to blood pressure testing and syphilis screening. Birth asphyxia is the most common cause of admission to the nursery and high perinatal mortality. The Apgar score at one minute is a good predictor of hyperlactatemia, however, x it over-diagnoses acidosis. Hypertensive mothers had 19% higher risk of having poor neonatal outcome for any given level of umbilical cord arterial lactate so additional attention to intrapartum and newborn monitoring for hypertensive mothers is required
- ItemOpen AccessAudit of maternal near misses at Queen Elizabeth central hospital, Chatinkha maternity unit(2017-07-01) Mvula, Priscilla Precious MwenechoMaternal near miss is an event in which a pregnant or recently delivered woman comes close to maternal death but does not die, due to either timely intervention or by pure chance. Evaluation of maternal near misses has been noted, in more developed countries, to aid in assessing the quality of obstetric care in a maternity unit and to formulate strategies to reduce the number of maternal deaths. It has been noted that up to 9 million women suffer from severe obstetric complications every year. This audit was done to determine the frequency of maternal near misses, to determine the proportion of near misses to maternal deaths, to assess the implementation of key evidence based interventions in women experiencing severe maternal morbidity. This was a prospective observational folder review where data was collected on standardized forms, from all admissions to the Chatinkha Maternity Unit at Queen Elizabeth Central Hospital between the months of July and December 2016. Data was entered into Epi Info and analyzed using Microsoft Excel and Epi Info. During this study period there were a total of 5463 deliveries in the unit, of which 5337 were live births. There were a total of 303 severe maternal complications. Using the WHO criteria, there were a total of 80(26.4%) near miss cases whilst 216(71.3%) fit the Haydom near misses criteria. There were 19 maternal deaths that occurred in the study vii period making a maternal mortality ratio of 356 per 100 000 live births. The leading cause of maternal near miss was obstetric haemorrhage (33.8%) followed by hypertensive disorders in pregnancy (32.9%), whilst pregnancy related infection (26.3%) was the commonest cause of maternal mortality. Maternal near misses are a common occurrence in our setting, and the main causes mirror those that cause maternal deaths. Obstetric haemorrhage and hypertensive disorders remains a big problem in our set up and there is need to be more diligent in preventing and treating these conditions.
