Magnesium Sulphate (MgS04) has been used for decades in obstetrics for the prevention and treatment of seizures in pre-eclamptic and eclamptic parturients. However, the effect of MgSO4 treatment on raised intracranial pressure (ICP) is still unclear.~Clinical signs of raised ICP are not specific and often difficult to interpret, especially during pregnancy and pre-eclampsia. Though the use of invasive devices is considered a gold standard in the measurement of ICP, Ocular sonography is a promising bedside tool, which serves as a noninvasive, readily available, and cost-effective means for indirectly measuring ICP.~Bedside ultrasound can be used as a point-of-care tool for rapidly measuring the optic nerve sheath diameter (ONSD), which is a validated indirect means for measuring ICP. An increase in ICP reflects as a raised ONSD since the optic nerve is surrounded by Dural sheath and cerebrospinal fluid (CSF) containing subarachnoid space, which is distensible in the retrobulbar segment, particularly when CSF pressures rise.
the effect of MgSO4 on ONSD in severely pre-eclamptic parturients has been underestimated. Though this study aims to evaluate the effect of magnesium sulphate on raised ICP in severely pre-eclamptic parturients using ocular ultrasonography to determine ONSD as a measure of ICP.
