Background: Hypertensive disorders represent the most common medical complication of pregnancy affecting between 7 to 15 percent of all gestation and account for approximately a quarter of all antenatal admission. In Bangladesh, the incidence of this killer disease is still high and it is the third major cause of maternal death in our country.

Objective: To evaluate pregnancy outcomes in severe preeclampsia.

Methods: The data were collected through the active participation of the patients' interviews by the performed proforma of data collection sheet and then data were gathered, decorated, and tabulated after data cleaning and edition. Then the results were found and they were tested by the Student's unpaired t-test (quantitative data) and chi-square test (qualitative data) to see their level of significance i,e p-value which was set as the cutoff level at <0.05. So if the p-value is >0.05 the results are not significant.

Results: The data analysis of 30 patients yielded the following results. The mean age of 30 mothers was 27.65 (± 5.85) years. The maximum 19 (63.33%) patients were from the 20-34 years age group. Among the 30 mothers with severe preeclampsia, 12(40%) were primiparous and the rest 18 (60%) were multiparous. To ensure safe delivery 14(46.67%) mothers adopted LSCS whereas 10(33.33%) adopted vaginal delivery with episiotomy. The rest 6 (20%) underwent VD. Regular ANC ensured only 6 (20%) respondents whereas the rest 80% replied that they were either irregular ANC or no ANC. The most common complications mothers faced were abruptio placenta (28.57%) followed by convulsion (14.28%) and HELLP syndrome (9.52%). Among the babies, 5% showed APGAR score above 7 at 1st minute whereas 58% showed the same score at 5 minutes.

Conclusion: In conclusion, it may be assumed that though various fetal and maternal morbidities may occur in the case of severe preeclampsia mortality is seen only in the case of neonates. Maternal mortality has almost disappeared from our perspective in the case of severe pre-eclampsia.

Introduction

Pre-eclampsia is a series of multi-system abnormalities usually occurring after 20 weeks of gestation with an ensuring diagnosis of new-onset hypertension (blood pressure at or above 140/90 mmHg) on two occasions at least 4 hours apart with significant proteinuria (a finding of protein in urine > 300 mg over a 24 hrs period) in a previous normotensive and nonproteinuric patient. Globally, each year more than four million women develop preeclampsia and approximately 100,000 women will have an eclamptic convulsion with over 90% occurring in developing countries[1].

It results in 12% of maternal deaths globally, up to 40% of maternal deaths in some countries and is responsible for the occurrence of up to 13% of stillbirths and 20% of early neonatal deaths [2]. Approximately 10-15% of maternal deaths in developing countries are associated with preeclampsia leading to eclampsia[3].

There is no concrete data found on the incidence of preeclampsia in our country, but calculated from the US Census Bureau, International Data Base, 2004, the extrapolated annual incidence of preeclampsia in Bangladesh is 76,032[4]. Our neighbouring country, India has incidence of preeclampsia, as recorded from hospital statistics, varying widely from 5 to 15% [5].

Bangladesh, the most densely populated country in South East Asia has high maternal mortality as well as perinatal mortality rate [6]. According to WHO severe preeclampsia accounts for 16.1% of maternal deaths in developed countries over the past 2 decades [7].

In pre-eclampsia, the normal endovascular invasion of cytotrophoblast into the spiral arteries fails to occur beyond the decidua-myometrial junction. As a result, the musculoelastic media in the myometrial segment remains responsive to vasoconstrictor stimuli resulting in decreased blood flow. There is acute atherosis of spiral arteries with obliteration of the lumen. Maternal illness varies from mild asymptomatic hypertension to neurological, renal, and cardiopulmonary compromise.

Concomitantly, some fetuses are healthy, while others experience severe intrauterine growth restriction. The maternal and perinatal mortality is thought to be <1% and 1% to 2% respectively.

While preeclampsia has the potential for serious complications, most cases of preeclampsia are mild and require minimal clinical treatment like increased maternal and fetal surveillance, blood pressure control and seizure prophylaxis, but ultimately delivery of the infant is the definitive treatment.

The decision to transfer women with preeclampsia for management and delivery elsewhere can create social hardship and may introduce morbidity risk for the infant. The challenge to clinicians lies in identifying patients who will suffer subsequent adverse outcomes from preeclampsia to intervene appropriately while minimizing unnecessary and potentially harmful interventions in patients who do not require them.

Severe preeclampsia and eclampsia are not distinct disorders but are differentiated according to their clinical syndrome. Although seizures define the condition of eclampsia, other neurological findings may be observed earlier in the continuum of preeclampsia. In preeclampsia, hypertension and proteinuria are present and when convulsions occur in addition to these signs, the condition is referred to as eclampsia [8]. The main aim of this study was to evaluate pregnancy outcomes in severe preeclampsia.

Materials and Methods

Study design: Observational cross-sectional study.

Place of study: The study was conducted among the admitted patients in the Department of Obstetrics &Gynaecology at BSMMU, Dhaka, Bangladesh.

Study population: The study was conducted among patients with severe preeclampsia admitted to the Department of Obstetrics & Gynaecology, BSMMU, Bangladesh.

Period of study: March 2015 to August 2015.

Sample size: 30 patients were selected by purposive sampling.

Inclusion Criteria

  • Pregnant women between 20-40 weeks of gestation.
  • Blood pressure ≥160/110mm of Hg with proteinuria.
  • Single intrauterine pregnancy.

Exclusion Criteria

  • Pregnant women <20 weeks and >40 weeks of gestation.
  • Gestational Hypertension.
  • Chronic Hypertension.
  • Antepartum Hemorrhage.
  • Presence of Diabetes mellitus.
  • Heart diseases.
  • Renal diseases.
  • HELLP syndrome.
  • Babies with Congenital Malformations.

Methodology: The interviews of the mothers were taken through a pre-structured questionnaire. The mothers were clinically assessed and supporting investigations were done to confirm the presence of medical and obstetrical risk factors contributing to severe preeclampsia. All the data were gathered, edited, decorated and finalized in figure and table form. As there was no hypothesis to be tested no statistical test was performed. The table and figure were plotted according to age, educational status, socio-economic status, BMI, mode of delivery, medical and obstetrical risk factors, APGAR score, perinatal outcome, neonatal death and their interval. The individual categorizations are given on the next page as the observations and results of this study. As the total sample size is 30 in this study the number of patients also manifests the percentage of patients here.

Main outcome variables studied: Preeclampsia- maternal outcome, perinatal age, parity, severity, mode of delivery, maternal complications and maternal mortality, perinatal outcome, birth weight, APGAR score, NICU admission, perinatal complications and perinatal mortality.

Procedures of data analysis and interpretation: After collection, data editing and clearing were done manually and prepared for data entry and analysis by using SPSS version 17. Student t-tests were done to compare the groups. P values <0.05 will be considered as significant.

Results

Out of 30 patients, the maximum number of patients were from the age group 20-34 years category.

The number was 19 (63.33%). Out of 30 mothers, 14 were nulliparous which was about 46.67% of the total study population.

The minimum number of pre-eclamptic mothers was grand multiparous (table-1& fig-I).

Discussion

This observational cross-sectional study was conducted in the Department of Obstetrics and Gynaecology, BSMMU during 6 months to evaluate pregnancy outcomes of severe preeclampsia. For this purpose, 30 pregnant women were purposively selected according to inclusion and exclusion criteria.

This study showed maximum patients (63.30%) were age group of 20 to 34 years and the mean age of the total study population was 27.65±5.85years. These figures indicate that younger women were more affected by severe preeclampsia. This corresponds with the studies of Moodley and Mashioane where the mean age was 28 years and also similar to Brown MA and Buddle ML [9].

Half of the severe pre-eclamptic women in this study were multiparous. Conde-Aguedelo and Belizam JM also found a similar pattern of risk factors among nulliparous and multiparous women [10]. Among the 17 (56.67%) multiparous women 13 (76.47%) had pregnancy-induced hypertension in their previous pregnancy. The presence of gestational hypertension in a previous pregnancy is a known risk factor for gestational hypertension in a subsequent pregnancy [11].

In my study 22 (73.33%) were urban residents among them 15 patients came from low-income families with poor nutritional status. The maximum number of mothers in this study did not undergo regular antenatal check-ups. The cause behind this unwanted scenario revealed a lack of knowledge, low socio-economic condition, lack of awareness, ignorance of family and lack of knowledge about the health facilities around them. Patients with severe eclampsia present with various symptoms but the commonest were headache, headache with visual disturbance, epigastric pain, and epigastric pain with vomiting.

The mode of delivery was chosen caesarean section in the case of 14 (46.67%) severe preeclampsia mothers for better perinatal outcomes whereas 10(33.33%) mothers delivered vaginally with episiotomy and 6(20%) delivered vaginally. The results were consistent with a report presented by Nabila et al. [12].

Abruptio placenta was observed as the maximal maternal complication (28.58%) in this study. This result is similar to that of Lee and his colleagues' report where 32% of the pre-eclamptic women had the same maternal complication [13]. The commonest complications in this study were abruptio placenta, convulsion and HELLP syndrome. These complications were similar to the findings of Murphy DJ and Stirrat GM [14] Abruptio placenta was the commonest maternal complication in our study which was also observed in the study of Al-Mulhim and his colleagues [15].

Regarding APGAR score this study found that 95% of neonates achieved a <7 score at 1 minute after birth and 58% achieved a>7 score 5 minutes after birth. 62% of babies required resuscitation and 45% of babies required admission to the neonatal ward. In another study, Nabila reported that in her study 58% of new newborns required resuscitation and 40% required neonatal support. McGarvey [16] found almost the same results that are consistent with our study results. Eighteen (60.0%) neonates had a birth weight of less than 2500gm with severe preeclampsia. These mean birth weights correspond to the mean gestational age of the different categories of preeclampsia. The observed trend of birth weight was also similar to those of other studies [17].

The lower birth weight observed in this study corresponds to that of Xiong X and Fraser WD's study where the birth weights were significantly lower in women with severe preeclampsia[18]. Preeclampsia is responsible for the occurrence of more than 40% of premature deliveries around the globe [19].

This was also observed in this study where 30% of mothers gave birth to premature babies with small for date and more than 10% of babies were given birth as premature but not small for date in this study. The results of this study showed no maternal death within the study period. The neonatal mortality rate was also low compared to the neonatal mortality of the Khomas region [20].

Conclusion

The absence of maternal mortality during the study period was encouraging. However, important findings indicate that the care given to pre-eclamptic women was not totally in line with international or regional guidelines for the management of preeclampsia. Expectant management of severe preeclampsia was not followed, as the same management was observed for mild preeclampsia in the same hospital as severe preeclampsia.

Interestingly, the caesarean section rate was very high the rate of prematurity and neonatal ICU admission was very high all pre-eclamptic women were treated with anti-hypertensive drugs irrespective of the severity of the disease. In the end, we may conclude here that though there are various fetal complications including LBW, IUGR, hyperbilirubinemia, birth asphyxia, neonatal septicemia etc. in the case of severe preeclampsia; no maternal mortality was seen.

Four neonates out of 30 died after birth proclaimed that we are still struggling to make neonatal death ZERO in case of severe preeclampsia. But it can be said boldly that modern diagnostic and treatment facilities help us to stop already maternal mortality in case of severe preeclampsia. We are hopeful that within the near future, we can prevent neonatal mortality in such maternal clinical conditions.

Recommendations

  • A case-control or cohort study is recommended.
  • A multicentered double-blinded study in the divisional/ tertiary hospitals of the whole of Bangladesh can reveal the real picture of fetomaternal complications in severe pre-eclampsia.
  • The study period should be long with more representative samples to get more precise results.
  • Multi-disciplinary approach to research work can make a study precise & more authentic in this regard.
  • The whole country patient's conditions should be recorded so that we can generate a protocol as a national guideline for effective prevention & management of high-risk pregnancies.

What does the study add to existing Knowledge: A high-risk pregnancy registry can prevent the serious complications of the perinatal period by regular follow-up.
