based on a careful analysis of medical care received before the onset of eclampsia , the following factors were judged to be at least partially responsible for the failure to prevent eclamptic convulsions : physician error ( n = 65 ) , magnesium sulfate failure ( n = 23 ) , late-onset eclampsia ( n = 22 ) , early onset ( less than 21 weeks ) preeclampsia/eclampsia ( n = 5 ) , abrupt onset eclampsia ( n = 32 ) , and failure of patient to start prenatal care before the onset of eclampsia ( n = 34 ) .
