Filter by:Preeclampsia/eclampsia is part of a spectrum of multi-systemic pregnancy disorder that contributes substantially to maternal and perinatal morbidity and mortality, especially in low resource setting. This study was done in Abakaliki, Ebonyi State, Southeast Nigeria. To compare the efficacy of loading dose of magnesium sulphate with that of the Pritchard regimen in the prevention of eclampsia in severe preeclampsia and recurrent fits in eclampsia in a low resource setting. A prospective, single blinded randomized controlled study of loading dose versus Pritchard regimens of MgSO4 at the Teaching Hospital Abakaliki. One hundred and twenty patients were recruited 60 to each arm using computer-generated numbers. Sociodemographic characteristics, efficacy and adverse effects of the drug on the mother and baby were noted.
Two hundred patients with severe PE were admitted prepartum to the ICU to stabilize blood pressure. They were randomly assigned to one of two groups (100 in each group): Group N received nitroglycerine intravenous infusion in a concentration of 1 mg/ml, thus 1µg/Kg/min equals to 4.8 ml/hr for an 80 Kg patient. Group L received labetalol intravenous infusion in a concentration of 10 mg/ ml, thus 50 mg/ml equals to 5 ml/hr. The starting infusion rate of the antihypertensive medication was 5 ml/hr. The infusion rate was titrated to stabilize systolic blood pressure (SBP) at 130-140 mmHg and diastolic blood pressure (DBP) at 80-90 mmHg (study end point) by adjusting the infusion rate as required either by maintaining the same infusion rate or by changing its infusion rate by 1 ml/hr up or down according to the clinical condition every 10 minutes. On any abrupt reduction in blood pressure below 120 mmHg for SBP or 80 mmHg for DBP, the infusion was immediately discontinued, and a bolus of 150 ml lactate ringer was given.

Acid/base imbalances are not well understood in pre-eclamptics, and better tools are needed to allow a thorough and meaningful evaluation. Disorders of electrolytes and albumin are common findings [13, 14], and the impact of such disorders on acid-base homeostasis has increasingly been acknowledged [4, 15]. The purpose of this prospective case-control study is to evaluate acid-base status in 100 women with mild or severe pre-eclampsia and 25 healthy controls by applying the Stewart Fencl's physicochemical acid-base model. We hypothesize that several simultaneous, and possibly offsetting, metabolic acid-base disorders will be identified and quantified, and that these may be useful to guide clinicians in their medical management and indication for delivery. Intermediate and long-term goals are to evaluate the ability of the Stewart Fencl's physicochemical acid-base model to guide fluid management and predict maternal and neonatal outcomes.
Preeclampsia is a pregnancy-specific, multisystem disorder that complicates approximately 5 % of pregnancies. Tracheal intubation in the women with severe pre-eclampsia is usually associated with exaggerated transient increases in blood pressure, heart rate and maternal plasma catecholamine concentrations. These changes may lead to maternal cerebral oedema, haemorrhage, left ventricular failure, pulmonary oedema or mortality, and reduce uterine blood flow which may adversely affect the neonatal wellbeing. Therefore, the attenuation of the haemodynamic responses to tracheal intubation in this unique group of patients is demanding for the best of both mother and foetus. The use of single remifentanil boluses of 0.5 to 1 µg/kg reduces effectively the haemodynamic and catecholamine responses to laryngoscopy and tracheal intubation in severe pre-eclamptics during Cesarean delivery under general anesthesia. Unfortunately, the use of 1 µg/kg doses are associated with more maternal hypotension and neonatal respiratory depression requiring resuscitation. Moreover, the use of preinduction remifentanil bolus of 0.5 µg/kg followed by a continuous infusion at 0.15-0.2 µg/kg/min is associated with significant attenuation of the maternal stress response to tracheal intubation with variable degree of neonatal depression in non-pre-eclamptic women. Whereas, the use of infusion rates of 0.1 µg/kg/min or less is less likely to produce neonatal depression. In our previous study, we demonstrated that the preoperative administration of dexmedetomidine 0.4 and 0.6 µg/kg/h, a specific alpha 2-adrenoceptor agonist, blunts the maternal haemodynamic and hormonal responses to Caesarean delivery under sevoflurane anaesthesia without adverse neonatal effects. However the use of 0.6 µg/kg/h doses is associated with higher postoperative sedation scores.
