Evaluation of a Skilled Birth Attendant pilot training program in Bangladesh.

OBJECTIVES: An evaluation of the pilot project of the Skilled Birth Attendant (SBA) training program has been undertaken to assess the strengths and weaknesses of the training program, the after training performances of the selected SBAs and to ascertain the sustainability of the program. METHODS: The study was conducted in three phases adopting both qualitative and quantitative methods: assessment of training program; evaluation of after training performances of SBAs; and evaluation of performance of providers in non-SBA areas. RESULTS: During the post-training period it was observed that on an average the SBAs performed 3-4 deliveries per month. They were able to perform different life saving skills. In the areas served by the SBAs, they performed 29% deliveries and 47% were performed by the TBAs. In control areas TBAs performed 61% deliveries. CONCLUSION: Overall, the study points to the efficacy of SBAs over traditional hands and the societal need for SBAs.

Verbal autopsy for maternal death.

This cross sectional study was done in Gopalganj district from September 1997 to August 1998. To ascertain the magnitude and causes of maternal deaths and perinatal and neonatal outcome of the babies. Two hundred five in maternal deaths occurring from 1994 to 1997 were investigated by verbal autopsy. Teenager mothers had more deaths in first pregnancy. Maternal deaths increased with gravidity above 30 years. Haemorrhage and eclampsia were common causes of death. Eclampsia was prominent in primigravids <20 years while haemorrhage occurred more in multigravidas between 25-35 years of age (P = 0.029 for age, P = <0.001 for gravidity). Nearly 64% of maternal deaths occurred in postpartum period. Among live births, 45.6% babies died before their first birth day. The findings support the need of increasing the age of marriage and first childbirth, through strengthened family planning programme and ensuring skilled birth attendance during delivery. It also stresses need for communication on danger signs of pregnancy and childbirth.

Increased concentrations of plasma neuropeptide Y in patients with eclampsia and preeclampsia.

OBJECTIVE: Epinephrine and norepinephrine are associated with the hyperstimulation of the sympathetic nervous system. Neuropeptide Y is a potent vasoconstrictive substance that is released in response to sympathetic nerve stimulation. STUDY DESIGN: The concentrations of plasma neuropeptide Y in pregnant patients with eclampsia (n = 8), preeclampsia (n = 8), and normotension (n = 8) were measured by radioimmunoassay on admission and 6 days after delivery. Correlations between plasma concentration of neuropeptide Y and mean arterial blood pressure were also evaluated in these patients on admission and 6 days after delivery. RESULTS: The plasma level of neuropeptide Y in women with eclampsia (P <.001) and preeclampsia (P <.003) was found to be significantly elevated with respect to that in normotensive pregnant women. At 6 days after delivery the concentration of plasma neuropeptide Y was significantly decreased in women with eclampsia, women with preeclampsia, and women with normotensive pregnancies compared with the value measured on admission (P <.0001, P <.0001, and P <.002, respectively). At admission the plasma neuropeptide Y level was positively correlated with mean arterial blood pressure in women with eclampsia and preeclampsia. However, no significant correlations were observed between plasma neuropeptide Y concentration and mean arterial blood pressure both at admission and 6 days after delivery in normotensive pregnant women and 6 days after delivery in women with eclampsia and preeclampsia. CONCLUSION: We have concluded that the level of neuropeptide Y in plasma is increased in women with eclampsia and preeclampsia. Elevated plasma neuropeptide Y levels may play a key role in the development of eclampsia and preeclampsia.

PIP: This study investigated the plasma concentrations of neuropeptide Y associated with the pre-eclamptic and eclamptic conditions. Subjects included patients in the third trimester of pregnancy admitted at Dhaka Medical College Hospital, Bangladesh, from January 1996 to March 1998 with untreated eclampsia (n = 8), pre-eclampsia (n = 8), and normotensive pregnancy (n = 8). Nonpregnant healthy volunteer women (n = 8) were also enrolled. Blood samples were collected and the concentrations of plasma neuropeptide Y were measured by radioimmunoassay on admission and 6 days after delivery. The correlations between plasma concentration of neuropeptide Y and mean arterial blood pressure were also evaluated in these patients. The findings showed that the plasma level of neuropeptide Y in women with eclampsia (P 0.001) and pre-eclampsia (P 0.003) was significantly elevated in comparison with normotensive pregnant women. At 6 days after delivery the concentration of plasma neuropeptide Y was significantly decreased in women with eclampsia, women with pre-eclampsia, and women with normotensive pregnancies compared with the value measured on admission (P 0.0001, P 0.0001, and P 0.002, respectively). At admission the plasma neuropeptide Y level was positively correlated with mean arterial blood pressure in women with eclampsia and pre-eclampsia. However, no significant correlations were observed between plasma neuropeptide Y concentration and mean arterial blood pressure both at admission and 6 days after delivery in normotensive pregnant women and 6 days after delivery in women with eclampsia and pre-eclampsia. The study concluded that the level of neuropeptide Y in plasma is increased in women with eclampsia and pre-eclampsia.

Increased concentrations of plasma epinephrine and norepinephrine in patients with eclampsia.

We measured plasma catecholamine concentrations on admission (after eclamptic fit) and after 6 days of delivery in 21 eclamptic patients and on admission in 15 normotensive pregnant women in Bangladesh. Plasma epinephrine and norepinephrine concentrations in eclamptic patients were significantly higher on admission than those of normotensive pregnant women (P < 0.0001). Plasma catecholamine concentrations and mean arterial blood pressure had return to be almost normal as normotensive pregnant women after 6 days of delivery, resulting in no correlation between mean arterial blood pressure and plasma catecholamines. On admission (after eclamptic fit) mean arterial blood pressure was positively correlated with plasma epinephrine (r = 0.626, P < 0.002) and norepinephrine (r = 0.553, P < 0.008) concentrations in patients with eclampsia. The amount of proteinuria was also significantly correlated with plasma epinephrine (r = 0.515, P < 0.02) and norepinephrine (r = 0.606, P < 0.003) concentrations. Number of convulsions was significantly correlated with concentrations of plasma epinephrine (r = 0.514, P < 0.02), norepinephrine (r = 0.521, P < 0.01) and mean arterial blood pressure (r = 0.535, P < 0.01). A positive correlation was found between time passed after convulsion with plasma epinephrine (r = 0.515, P < 0.02) and norepinephrine (r = 0.570, P < 0.006) concentrations. These suggested that the increased plasma levels of epinephrine and norepinephrine in eclamptic patients were well correlated with the severity of the clinical features of eclampsia.

Correlated plasma elastase and sera cytotoxicity in eclampsia. A possible role of endothelin-1 induced neutrophil activation in preeclampsia-eclampsia.

The activation of neutrophils was studied in preeclampsia (n = 10) and eclampsia (n = 20) compared to normotensive controls (n = 10) and nonpregnant essential hypertensives (n = 10). Plasma elastase levels were raised in preeclampsia (0.53 +/- 0.32 microgram/mL, P < .002) and eclampsia (1.26 +/- 0.8 microgram/mL, P < .001) respectively compared to normal pregnancies (0.032 +/- 0.009 microgram/mL). The plasma elastases were more elevated in eclamptic cases compared to essential hypertensive (0.53 +/- 0.27 microgram/mL; P = .01) patients. We analyzed the correlation among elastase values, systolic (SBP), mean blood pressures (MBP), endothelin-1 (ET-1) levels and sera cytotoxicity (as measured by fura-2 release from human umbilical venous endothelial cell culture) in eclamptic cases. SBP and MBP were significantly correlated with plasma elastase levels in preeclampsia (r = 0.67, 0.63, respectively; P < .03) and eclampsia (r = 0.49, 0.49, respectively; P < .02). ET-1 levels were correlated with SBP (P = .003) and MBP (P = .001) and corresponding elastase levels (r = 0.606, P < .003) in eclamptic patients. Doses of 10, 25, and 50 pmol/mL of ET-1 increased elastase release in human neutrophil cultures dose and time dependently. Cytotoxicity of eclamptic sera correlated (P < .001) to the corresponding plasma elastase values. Therefore, this study suggests that neutrophil activation and ET-1 induced neutrophil activation occurs in this disease.

Plasma P selectin (GMP-140) and glycocalicin are elevated in preeclampsia and eclampsia: their significances.

OBJECTIVE: We measured the concentrations of plasma P selectin (or GMP-140) and glycocalicin in preeclamptic and eclamptic women. Correlations between these two parameters and blood pressures, platelet counts, or plasma thrombin-antithrombin complex values were evaluated. STUDY DESIGN: By use of enzyme-linked immunosorbent assays we measured the plasma GMP-140 and glycocalicin levels in normal pregnancies (n = 10) and preeclamptic (n = 10) and eclamptic (n = 20) pregnancies. The glycocalicin index was calculated as follows: (glycocalicin x [250 x 10(6)/ml])/(Individual platelet counts). Correlations between plasma GMP-140, glycocalicin, glycocalicin index values, blood pressures, platelet counts, and plasma thrombin-antithrombin complex values were analyzed. RESULTS: Plasma GMP-140 levels were found to be significantly elevated in preeclamptic (p < 0.0005) and eclamptic cases (p < 0.0001) compared with normotensive controls. Plasma glycocalicin (p = 0.01, 0.007) and glycocalicin index (p = 0.005, 0.002) values were also markedly elevated in preeclamptic and eclamptic patients compared with normal pregnant patients. Significant correlations between platelet counts or plasma thrombin-antithrombin complex levels and their corresponding plasma GMP-140 and glycocalicin and glycocalicin index values have been found in preeclamptic and eclamptic cases. However, blood pressures had correlations with GMP-140, glycocalicin, and glycocalicin index values in eclamptic cases. CONCLUSIONS: We demonstrated an elevation of plasma GMP-140 and platelet glycocalicin in preeclampsia and eclampsia. This study also reflects the usefulness of glycocalicin as a marker of platelet activation or turnover and endothelial dysfunction in these diseases.

Blood coagulation and fibrinolysis in eclamptic patients and their correlation with the clinical signs.

We studied the impact of blood coagulation and fibrinolysis on the clinical features of eclamptic patients (n = 20) in Bangladesh. The variables used were edema, proteinuria, blood pressure, number of convulsions, level of consciousness at the time of admission, thrombin antithrombin complexes (TAT), antithrombin (AT) III (%) activity and antigen, D dimer fibrin degradation product and alpha 2-plasmin inhibitor-plasmin complex (PIC) in plasma. Canonical correlation analysis was made to obtain clinical index, eclampsia index and two coagulation indices. On admission, the mean values of coagulation parameters were AT III activity: 83.2% (range 57-108), TAT complex: 47.6 ng/ml (range 11.5-60), D dimer: 1,693 ng/ml (range 417-8,276) and PIC 1.4 mg/ml (range 0.4-3.3). We found a significant correlation between the eclampsia index and clinical index (r = 0.601; p = 0.01). Gestosis index, clinical index, and eclampsia index have also a strong correlation with the coagulation index (r = 0.695, p < 0.005; r = 0.871, p < 0.0001 and r = 0.805, p < 0.0001, respectively). Coagulation and fibrinolysis were markedly activated in eclampsia. The correlation between the clinical status and coagulation status in this study suggested a close relation between the coagulation and the development and progression of the disease.

Maternal mortality: national versus hospital situation.

A retrospective analysis of the causes of maternal mortality in two academic hospitals of Dhaka city over a 2-year period was carried out and compared with national figures. These are the country's chief referral institutions, where only the critically ill are admitted. Currently, the national maternal mortality ratio (MMR) is 5.6/1000 live births, while in Dhaka Medical College Hospital the case fatality ratios (CFR) were 24.4 and 17.2 in 1992 and 1993, respectively. In Mitford Hospital the CFR was 11.1 and 5.4/1000 live births, during the same periods. The most common cause of maternal death at the national level was postpartum hemorrhage and at medical college hospitals it was eclampsia. If we can strengthen emergency obstetric care at all levels, we can reduce maternal mortality bolh at the national level and at the referral hospitals.
