ABSTRACT
Hemolytic diseases in fetus and newborn were known for years; the principle of these pathologies is defined Basically entrance of fetal blood cells to maternal circulation results in these ranges of diseases. Risk factor determination, early diagnosis of F.M H and adequate dosage of Anti - D Ig administration will be attempted to prevent subsequent adverse outcome on fetus and newborn. The quantification of fetal cells in the maternal circulation post - curettage miscarriage remains an important goal to prevent active immunization in mother. In this cross sectional study, during six months, from April 2004, one hundred patients post - abortion therapeutic curettage enrolled, in Ghaem Hospital, Mashhad University. Maternal age, gestational age, maternal blood group and Rh, gravidity, severity of maternal hemorrhage, HcT, BP and duration of vaginal bleeding were recorded. The KB test was done in all patients amount of FIMIH and Rh IgG dosage in positive KB patients were calculated. Data were analyzed with SPSS [Ver. 10] software. The KB test was positive in 35% of the patient. Gestational age, maternal H.ct, pain and severity of hemorrhage had significant relation to K.B test positive. F.M.H was 0.1-5 cc in 17 patients and in 18 it was less. Lower gestational age in abortion time decreases FMH risk the usual Rh - IgG dosage [50 micro gr] sounded to be adequate for Rh Immunization after post - abortion therapeutic curettage
