Methods:A double-blind, randomized placebocontrolledstudy was undertaken of preeclamptic singleton women undergoing elective or emergency lower-segment CS atKasrAlainy during the period from September 2019 toFebruary 2020. Patients were randomly assigned (1:1) using computer-generated random numbers to receive either 1 g TA or 5% glucose over 15 minutes before surgery. Preoperative and postoperative complete blood count, hematocrit values, and maternal weight were used to calculate the estimated blood loss (EBL) during CS. Main outcome measures: EBL during and after CS in preeclamptic patients. Results: Analyses included 35 women in each group. Mean EBL was significantly higher in the placebo group (819 ± 172 mL) than in the TA group(383.3 ± 140.7 mL)(P < 0.001). Mean EBL was significantly lower in mild than in severe preeclampsia.There were no reports of thromboembolic events postoperatively. Conclusions: Preoperative administrationof TA in preeclampticpatients safely and effectively reduces blood loss during elective or emergency lower-segment CS without any recorded adverse effects. Blood loss is significantly lower in mild than severe preeclampsia after TA administration ER -
