Protocol summary

Study aim
Determining the effectiveness of prophylactic administration of fibrinogen in reducing bleeding during cesarean section
Design
Clinical trial with control group, with parallel groups, double-blind, randomized with dice tose, phase 2 on 105 patients.
Settings and conduct
After obtaining informed consent, all candidates for elective cesarean section in the operating room of Imam Hossein Hospital in Tehran, patients with uncontrolled underlying disease, previous surgical history in the current operation field, substance abuse, and recent history of coagulation disease or use of anticoagulants prior to hospitalization will be excluded from the study. In the fibrinogen group, patients receive 1 gram of this drug in 50 ml of distilled water through an infusion pump over ten minutes. In the control group, 50 ml of distilled water will be used in the same way as above. An anesthesia technician selects one of the syringes containing fibrinogen or placebo for the patient without informing the anesthesiologist and the patient. The questionnaire is delivered to the first technician.
