Low-risk women were identified as the patients having no underlying medical problems (diabetes, hypertension, cardiac disease, coagulopathy, etc.), preeclampsia, selleck placenta previa, abruptio placenta, chorioamnionitis, previous myomectomy/septum resection, myoma uteri.6 Hemorrhage was defined as a decrease in hemoglobin concentration of 30% or greater which estimated blood loss greater than 1500 ml.7 The patients with antenatal or any history of severe bleeding and preoperative Hb levels below 10 g/dl

and women who had elective or eventful cesarean sections were excluded. Detailed chart review was conducted to collect demographic data, assess intraoperative factors and analyze postoperative courses. A total of 87 women during April to see more August 2011 underwent unplanned and uneventful

cesarean section in our clinic. The mean age of subjects was 28.2 ± 5.2 year in range of 17–42 years. General anesthesia was used for all cases. Routine Hb and Hct measurement and blood-type sampling and screening test were performed just prior to surgery and Hb measurement was repeated 12 h after the surgery. None of the patients showed any subjective symptoms of anemia, pulse rate above 95 beats/min and blood pressure under 95/65 mmHg. The mean preoperative hemoglobin was 12.4 ± 0.95 g/dl, whereas it was 11.8 ± 1.08 g/dl, postoperatively and the mean preoperative hematocrit was 37.5 ± 2.5%, whereas it was 35.8 ± 2.8% postoperatively (P < 0.001). Demographic and laboratory data are shown in Tables 1 and 2. None of cases had Hb dropped more than 30%. About 75% of the patients who experienced a decline, the hemoglobin levels dropped less than 10%

of the preoperative value and in 15%, Hb level decrease was between 10 and 20% and just in two cases were more than 20% that one Thymidine kinase of them had 42 years and five parity and the other was 35 years and had two parity and history of two abortion. Also 7.5% had no change in their Hb concentration. Maternal age, number of gestation, previous delivery, abortion and type of blood groups showed no statistically significant difference (P > 0.05). There was no blood transfusion among the 87 subjects. Reduction of unnecessary and unneeded laboratory tests could result decreasing the costs of health-care without affecting the quality of it. Combs et al reported that women undergoing cesarean delivery experienced only a mean drop of 4.0–4.2% in Hct whereas 17% had no decline.4 Another study by Kaplan et al on usefulness of preoperative laboratory screening found that blood types and screen testing are unnecessary and suggested to be eliminated since they did not contribute to treatment8 and in the similar study published by Larsen et al, the result revealed that frequency of blood transfusion related to unplanned and uneventful cesarean section was 0%.
