A Study Of Incidence Of Pre-Eclampsia In Relation To Parity

The glory of attaining motherhood is often associated with shadows of life threatening dangers to the mother and the unborn child, even though pregnancy and childbirth is purely a physiological process. 
Pre-eclampsia is one of the complication of pregnancy and contributes significantly maternal as well as perinatal morbidity and mortality(1,2). This disorder is characterised by involvement of cardiovascular, coagulation, renal and hepatic system(3,4). This is a life threatening complication of pregnancy and is characterised by high blood pressure and proteinuria(5). 
Extensive studies have been made to detect the aetiology and pathogenesis of the condition. But despite decade of research, the aetiology of PIH has remained elusive and no definite and universally accepted conclusion has been reached(6). During normal pregnancy, renal blood flow and glomerular filtration increases appreciably. With the development of pre-eclampsia renal perfusion and glomerular filtration are reduced, resulting in impairment of renal function. The main characteristic feature of pre-eclampsia i.e. edema, proteinuria and hypertension are due to renal involvement. There occurs renal vasospasm which eventually produce endothelial damage, proteinuria and hypertension(7,8,9). 
So considering the mater related to our country an attempt has been made to study the incidence of pre-eclampsia in relation to parity.
