Effect of Local Fibrinogen Administration on Postoperative Bleeding in Open Prostatectomy Surgery.

Background: Open prostatectomy is still accompanied by some postoperative bleeding. Prescribing fibrinogen to promote clot formation in patients with bleeding is of critical importance. This research studied the effects of local injection of fibrinogen on level of postoperative bleeding in open prostatectomy.

Methods: Overall, 44 patients were randomly entered in a study on open prostatectomy. Patients in the intervention group received local injections of 500 mg fibrinogen (20 mL) dissolved in distilled water, and the control group patients only received 20 mL of normal saline, where the injections were given by the surgeon at the prostatectomy operation site. All patients were tested for hemoglobin, hematocrit, PT, PTT, INR, and fibrinogen level. Also, the amount of blood loss and requirement for blood products were recorded.

Results: The study groups showed no difference regarding baseline variables. One patient in the fibrinogen group (1.66%) and four patients in the control group (6.66%) received blood products (P < 0.05), and the blood drainage tube at 24 hours after operation was 36.50) 18.70 (mL in the fibrinogen group and 151.36) 120.58 (mL in the control group (P = 0.005). There were no differences in hemoglobin, hematocrit, PT, PTT, INR, and serum fibrinogen level between the groups at any time.

Conclusions: The current study demonstrated that using fibrinogen in patients with high bleeding risk may effectively reduce the amount of bleeding and its subsequent blood transfusion requirement, after open prostatectomy surgery.
